    Individual dietary choices are primarily influenced by such considerations as taste, cost, convenience and nutritional value of foods. The current obesity epidemic has been linked to excessive consumption of added sugars and fat, as well as to sedentary lifestyles. Fat and sugar provide dietary energy at very low cost. Food pricing and marketing practices are therefore an essential component of the eating environment. Recent studies have applied economic theories to changing dietary behavior. Price reduction strategies promote the choice of targeted foods by lowering their cost relative to alternative food choices. Two community-based intervention studies used price reductions to promote the increased purchase of targeted foods. The first study examined lower prices and point-of-purchase promotion on sales of lower fat vending machine snacks in 12 work sites and 12 secondary schools. Price reductions of 10%, 25% and 50% on lower fat snacks resulted in an increase in sales of 9%, 39% and 93%, respectively, compared with usual price conditions. The second study examined the impact of a 50% price reduction on fresh fruit and baby carrots in two secondary school cafeterias. Compared with usual price conditions, price reductions resulted in a four-fold increase in fresh fruit sales and a two-fold increase in baby carrot sales. Both studies demonstrate that price reductions are an effective strategy to increase the purchase of more healthful foods in community-based settings such as work sites and schools. Results were generalizable across various food types and populations. Reducing prices on healthful foods is a public health strategy that should be implemented through policy initiatives and industry collaborations.

    This study examines the importance of food prices and restaurant and food store outlet availability for child body mass index (BMI). We use the 1998, 2000 and 2002 waves of the child-mother merged files from the 1979 cohort of the National Longitudinal Survey of Youth combined with fruit and vegetable and fast food price data obtained from the American Chamber of Commerce Researchers Association and outlet density data on fast food and full-service restaurants and supermarkets, grocery stores and convenience stores obtained from Dun & Bradstreet. Using a random effects estimation model, we found that a 10% increase in the price of fruits and vegetables was associated with a 0.7% increase in child BMI. Fast food prices were not found to be statistically significant in the full sample but were weakly negatively associated with BMI among adolescents with an estimated price elasticity of -0.12. The price estimates were robust to whether we controlled for outlet availability based on a per capita or per land area basis; however, the association between food outlets and child BMI differed depending on the definition. The associations of fruit and vegetable and fast food prices with BMI were significantly stronger both economically and statistically among low- versus high-socioeconomic status children. The estimated fruit and vegetable and fast food price elasticities were 0.14 and -0.26, respectively, among low-income children and 0.09 and -0.13, respectively, among children with less educated mothers.

    Full Text Available The paper summarizes key findings of alternative lines of research on the relationship between food and fuel markets, and identifies gaps between two bodies of literature: one that investigates the relationship between food and fuel prices, and another that investigates the impact of the introduction of biofuels on commodity-food prices. The former body of literature suggests that biofuel prices do not affect food-commodity prices, but the latter suggests it does. We try to explain this gap, and then show that although biofuel was an important contributor to the recent food-price inflation of 2001–2008, its effect on food-commodity prices declined after the recession of 2008/09. We also show that the introduction of cross-price elasticity is important when explaining soybean price, but less so when explaining corn prices.

  8. Food Price Volatility and Decadal Climate Variability

    Brown, M. E.

    2013-12-01

    The agriculture system is under pressure to increase production every year as global population expands and more people move from a diet mostly made up of grains, to one with more meat, dairy and processed foods. Weather shocks and large changes in international commodity prices in the last decade have increased pressure on local food prices. This paper will review several studies that link climate variability as measured with satellite remote sensing to food price dynamics in 36 developing countries where local monthly food price data is available. The focus of the research is to understand how weather and climate, as measured by variations in the growing season using satellite remote sensing, has affected agricultural production, food prices and access to food in agricultural societies. Economies are vulnerable to extreme weather at multiple levels. Subsistence small holders who hold livestock and consume much of the food they produce are vulnerable to food production variability. The broader society, however, is also vulnerable to extreme weather because of the secondary effects on market functioning, resource availability, and large-scale impacts on employment in trading, trucking and wage labor that are caused by weather-related shocks. Food price variability captures many of these broad impacts and can be used to diagnose weather-related vulnerability across multiple sectors. The paper will trace these connections using market-level data and analysis. The context of the analysis is the humanitarian aid community, using the guidance of the USAID Famine Early Warning Systems Network and the United Nation's World Food Program in their response to food security crises. These organizations have worked over the past three decades to provide baseline information on food production through satellite remote sensing data and agricultural yield models, as well as assessments of food access through a food price database. Econometric models and spatial analysis are used

  9. On Food Price Implications from Expanded Bioenergy Production

    Energy Technology Data Exchange (ETDEWEB)

    Bryngelsson, David K.

    2012-07-01

    Bioenergy has been put forward as a solution to energy security and at the same time to climate change. It is, however, dependent on productive agricultural land, which is a limited resource. Introduction of bioenergy on a large scale will thus compete with food production and natural forests for productive land, a competition expected to affect food prices. In this thesis I focus on poverty nourishment issues related to changing food prices and on the mechanisms of land-use competition and how they affect food prices. In the first paper we use two established indicators for poverty and sensitivity to food-price changes, to capture peoples' vulnerability to rising food-prices, in four Sub-Sahara African countries/regions. In contrast to previous studies, we include all food products instead of just one or a few main staples. We found that the vast majority of people are net consumers of food and that the inclusion of more than main staples increases their net position as consumers and thus vulnerability to high food prices. In paper two and three a conceptual and transparent partial equilibrium model of global land-use competition is developed, analyzed and applied. The model is to a large degree analytically explored and price differentials between crops are derived. The model is subjected to a detailed characterization of its mechanisms and parameters in which parameters that are critical to results and conclusions from the model are detected and their impacts depicted. We conclude that the total amount of productive agricultural area is of crucial importance to the price impacts from large-scale introduction of bioenergy. Yields of bioenergy crops are also important since they determine the amount of land required to produce the bioenergy.

  10. PRICE ON THE ORGANIC FOOD MARKET

    Full Text Available The main objective of this paper is to present prices on PAE market (PAE- organic foods market. Prices are analyzed in terms of importance and the main factors that contribute to their establishment (quality of products, distribution channels, certification and eco-labeling system, customer segments and market development stage. This paper is based on the investigation of secondary sources, of specialized literature related to PAE consumers. The paper shows that are used three strategic options of prices: prices with high rigidity located in a low or high level and fluctuating prices, characterized by variations on short periods of time. Price is a very important barrier to market development but this importance can be mitigated through appropriate communication policies with the market, which are essential especially for markets in early stages of development.

    This study aims to describe the prices of food groups consumed in Brazil considering the nature, extent, and purpose of their processing. Data were obtained from the Brazilian Household Budget Survey for 2008-2009. The mean prices of the groups (natural, cooking ingredients, processed, and ultra-processed) and their respective food subgroups were estimated for Brazil according to income, region, and area. Natural products and cooking ingredients showed lower prices per calorie when compared to the other groups, suggesting an economic advantage to preparing meals at home when compared to replacing them with ultra-processed foods. Families with the highest income paid the highest prices for their food, while families in the Northeast and North regions and rural areas paid the lowest. While fresh foods (meat, milk, fruit, and vegetables) tend to cost more than ultra-processed foods, dry grains (like rice and beans) are a more economical alternative for adopting healthy eating practices.

    Importance Fiscal food policies (e.g., taxation) are increasingly proposed to improve population-level health, but their impact on health disparities is unknown. Objective We estimated subgroup-specific effects of fast food price changes on fast food consumption and cardio-metabolic outcomes, hypothesizing inverse associations between fast food price with fast food consumption, BMI, and insulin resistance and stronger associations among blacks (vs. whites) and participants with relatively lower education or income. Design 20-year follow-up (5 exams) in a biracial U.S. prospective cohort: Coronary Artery Risk Development in Young Adults (CARDIA) (1985/86–2005/06, baseline n=5,115). Participants Aged 18–30 at baseline; designed for equal recruitment by race (black/white), educational attainment, age, and gender. Exposures Community-level price data from the Council for Community and Economic Research (C2ER) temporally- and geographically-linked to study participants’ home address at each exam. Main outcome and measures Participant-reported number of fast food eating occasions per week; BMI (kg/m2) from clinical assessment of weight and height; homeostatic model assessment insulin resistance (HOMA-IR) from fasting glucose and insulin. Covariates included individual- and community-level social and demographic factors. Results In repeated measures regression, multivariable-adjusted associations between fast food price and consumption were non-linear (quadratic, p<0.001), with significant inverse estimated effects on consumption at higher prices; estimates varied according to race (interaction term p=0.04), income (p=0.07), and education (p=0.03). For example, at the 10th percentile of price ($1.25/serving), blacks and whites had mean fast food consumption (times/week) of 2.2 (95% CI: 2.1–2.3) and 1.6 (1.5–1.7), respectively, while at the 90th percentile of price ($1.53/serving), respective mean consumption estimates were 1.9 (1.8–2.0) and 1.5 (1.4–1.6).

    Identifying food pricing strategies to encourage purchases of lower-calorie food products may be particularly important for black Americans. Black children and adults have higher than average obesity prevalence and disproportionate exposure to food marketing environments in which high calorie foods are readily available and heavily promoted. The main objective of this study was to characterize effects of price on food purchases of black female household shoppers in conjunction with other key decision attributes (calorie content/healthfulness, package size, and convenience). Factorial discrete choice experiments were conducted with 65 low- and middle-/higher-income black women. The within-subject study design assessed responses to hypothetical scenarios for purchasing frozen vegetables, bread, chips, soda, fruit drinks, chicken, and cheese. Linear models were used to estimate the effects of price, calorie level (or healthfulness for bread), package size, and convenience on the propensity to purchase items. Moderating effects of demographic and personal characteristics were assessed. Compared with a price that was 35% lower, the regular price was associated with a lesser propensity to purchase foods in all categories (β = -0.33 to -0.82 points on a 1 to 5 scale). Other attributes, primarily calorie content/healthfulness, were more influential than price for four of seven foods. The moderating variable most often associated with propensity to pay the regular versus lower price was the reported use of nutrition labels. Price reductions alone may increase purchases of certain lower-calorie or more healthful foods by black female shoppers. In other cases, effects may depend on combining price changes with nutrition education or improvements in other valued attributes.

  14. New Local, National and Regional Cereal Price Indices for Improved Identification of Food Insecurity

    Large price increases over a short time period can be indicative of a deteriorating food security situation. Food price indices developed by the United Nations Food and Agriculture Organization (FAO) are used to monitor food price trends at a global level, but largely reflect supply and demand conditions in export markets. However, reporting by the United States Agency for International Development (USAID)'s Famine Early Warning Systems Network (FEWS NET) indicates that staple cereal prices in many markets of the developing world, especially in surplus-producing areas, often have a delayed and variable response to international export market price trends. Here we present new price indices compiled for improved food security monitoring and assessment, and specifically for monitoring conditions of food access across diverse food insecure regions. We found that cereal price indices constructed using market prices within a food insecure region showed significant differences from the international cereals price, and had a variable price dispersion across markets within each marketshed. Using satellite-derived remote sensing information that estimates local production and the FAO Cereals Index as predictors, we were able to forecast movements of the local or national price indices in the remote, arid and semi-arid countries of the 38 countries examined. This work supports the need for improved decision-making about targeted aid and humanitarian relief, by providing earlier early warning of food security crises.

    In light of proposals to improve diets by shifting food prices, it is important to understand how price changes affect demand for various foods. We reviewed 160 studies on the price elasticity of demand for major food categories to assess mean elasticities by food category and variations in estimates by study design. Price elasticities for foods and nonalcoholic beverages ranged from 0.27 to 0.81 (absolute values), with food away from home, soft drinks, juice, and meats being most responsive to price changes (0.7-0.8). As an example, a 10% increase in soft drink prices should reduce consumption by 8% to 10%. Studies estimating price effects on substitutions from unhealthy to healthy food and price responsiveness among at-risk populations are particularly needed.

    2016-12-01

    Full Text Available This study examines the long and short run relationships between oil price and food price volatility as well as the causal link between them. The study used annual food price volatility index from FAO from 2000 to 2013 and crude oil price from U.S. Energy Information and Administration (EIA from 2000 to 2013. The Johansen and Jesulius co-integration test revealed that there is a long run relationship between oil price and domestic food price volatility. The vector error correction model indicated a positive and significant short run relationship between oil price and food price volatility. The Granger causality test revealed a unidirectional causality with causality running from oil price to food price volatility but not vice versa. It is recommended that policies and interventions that will help reduce uncertainty about food prices such as improved market information, trade policies and investment in research and development among others should be encouraged. Also to reduce the effect of oil price shock, it is recommended that government should subsidise pump price of refined oil, seek alternative sources of energy and there should be less dependence on oil for fertilizer production.

    Full Text Available This study examines the effect of oil price on the volatility of food price in Nigeria. It specifically considers the long-run, short-run, and causal relationship between these variables. Annual data on oil price and individual prices of maize, rice, sorghum, soya beans, and wheat spanning from 2000 to 2013 were used. The price volatility for each crop was obtained using Generalized Autoregressive Conditional Heteroskedascity (GARCH (1, 1 model. Our measure of oil price is the Refiner acquisition cost of imported crude oil. The Augmented Dickey–Fuller and Phillip–Perron unit root tests show that all the variables are integrated of order one, I (1. Therefore, we use the Johansen co-integration test to examine the long-run relationship. Our results show that there is no long-run relationship between oil price and any of the individual food price volatility. Thus, we implement a VAR instead of a VECM to investigate the short-run relationship. The VAR model result revealed a positive and significant short-run relationship between oil price and each of the selected food price volatility with exception of that of rice and wheat price volatility. These results were further confirmed by the impulse response functions. The Granger causality test result indicates a unidirectional causality from oil price to maize, soya bean, and sorghum price volatilities but does not show such relationship for rice and wheat price volatilities. We draw some policy implications of these findings.

    Recent years have seen considerable interest in examining the impact of food prices on food consumption and subsequent health consequences. Fiscal policies targeting the relative price of unhealthy foods are frequently put forward as ways to address the obesity epidemic. Conversely, various food subsidy interventions are used in attempts to reduce levels of under-nutrition. Information on price elasticities is essential for understanding how such changes in food prices affect food consumption. It is crucial to know not only own-price elasticities but also cross-price elasticities, as food substitution patterns may have significant implications for policy recommendations. While own-price elasticities are common in analyses of the impact of food price changes on health, cross-price effects, even though generally acknowledged, are much less frequently included in analyses, especially in the public health literature. This article systematically reviews the global evidence on cross-price elasticities and provides combined estimates for seven food groups in low-income, middle-income and high-income countries alongside previously estimated own-price elasticities. Changes in food prices had the largest own-price effects in low-income countries. Cross-price effects were more varied and depending on country income level were found to be reinforcing, undermining or alleviating own-price effects.

    This purpose of this paper is to investigate price transmission patterns through selected Danish food chains – from primary production to processing, from processing to wholesale and from wholesale to retail prices. Specifically, the study addresses the following research questions: To what extent...... are commodity prices transmitted from one stage to another in the food chain? What is the time horizon in the price transmission? Is price transmission symmetric – in the short run and in the long run? Is the degree of price transmission affected by the degree of concentration in the supply and demand stage...... considered? These questions are analysed theoretically and empirically using econometric analysis. 6 food chains are investigated: pork, chicken, eggs, milk, sugar and apples. Preliminary empirical results suggest that for most commodities, price transmission tends to be upward asymmetric, i.e. stronger...

    Food affordability and quality can influence food choice. This research explores the impact of geographic factors on food pricing and quality in Western Australia (WA). A Healthy Food Access Basket (HFAB) was cost and a visual and descriptive quality assessment of 13 commonly consumed fresh produce items was conducted in-store on a representative sample of 144 food grocery stores. The WA retail environment in 2010 had 447 grocery stores servicing 2.9 million people: 38% of stores the two major chains (Coles® Supermarkets Australia and Woolworths ® Limited) in population dense areas, 50% were smaller independently owned stores (Independent Grocers Association®) in regional areas as well, and 12% Indigenous community stores in very remote areas. The HFAB cost 24% (p<0.0001) more in very remote areas than the major city with fruit (32%, p<0.0001), vegetables (26.1%, p<0.0005) and dairy (40%, p<0.0001) higher. Higher price did not correlate with higher quality with only 80% of very remote stores meeting all criteria for fresh produce compared with 93% in Perth. About 30% of very remote stores did not meet quality criteria for bananas, green beans, lettuce, and tomatoes. With increasing geographic isolation, most foods cost more and the quality of fresh produce was lower. Food affordability and quality may deter healthier food choice in geographically isolated communities. Improving affordability and quality of nutritious foods in remote communities may positively impact food choices, improve food security and prevent diet-sensitive chronic disease. Policy makers should consider influencing agriculture, trade, commerce, transport, freight, and modifying local food economies.

    World food prices hit an all-time high in February 2011 and are still almost two and a half times those of 2000. Although three billion people worldwide use seafood as a key source of animal protein, the Food and Agriculture Organization (FAO) of the United Nations–which compiles prices for other major food categories–has not tracked seafood prices. We fill this gap by developing an index of global seafood prices that can help to understand food crises and may assist in averting them. The fish price index (FPI) relies on trade statistics because seafood is heavily traded internationally, exposing non-traded seafood to price competition from imports and exports. Easily updated trade data can thus proxy for domestic seafood prices that are difficult to observe in many regions and costly to update with global coverage. Calculations of the extent of price competition in different countries support the plausibility of reliance on trade data. Overall, the FPI shows less volatility and fewer price spikes than other food price indices including oils, cereals, and dairy. The FPI generally reflects seafood scarcity, but it can also be separated into indices by production technology, fish species, or region. Splitting FPI into capture fisheries and aquaculture suggests increased scarcity of capture fishery resources in recent years, but also growth in aquaculture that is keeping pace with demand. Regionally, seafood price volatility varies, and some prices are negatively correlated. These patterns hint that regional supply shocks are consequential for seafood prices in spite of the high degree of seafood tradability. PMID:22590598

  9. Local Staple Food Price Indices in the Age of Biofuels

    2012-01-01

    In many poor, food insecure regions, agriculture is a primary source of income and farmers are reliant both on their own production and on purchasing food in the market to feed their families. Large local food price increases over a short time period can be indicative of a deteriorating food security situation and may be the consequence of weather-related food production declines, Dr can simply be the result of price transmission from the international commodity market. Food price indices developed by the United Nations Food and Agriculture Organization (FAO) are used to monitor food price trends at a global level, but largely reflect supply and demand conditions in export markets far from the places where the chronically food insecure live. A much better understanding of how local staple food prices in isolated regions such as West Africa that grow most of the food they eat to better understand the impact of global commodity market transformations on sensitive communities at the margin. This information will also enable improved strategies for these farmers who are extraordinarily sensitive to climate change impacts on agricultural growing conditions.

    Full Text Available Iran has experienced high food prices in recent years. This paper examines the welfare impacts of rising major food groups' prices on Iranian urban households using Quadratic Almost Ideal Demand System (QUAIDS approach. The elasticity coefficients derived from QUAIDS are used to estimate Compensated Variations (CV.The study uses Iranian Household Expenditure and Income Survey (HEIS raw data, encompassing both low and high price periods. Prices of all food and agricultural products increased during the entire survey period of 2004 to 2012. Based on our estimates, the food groups of cereals, dairy products, vegetable and pulses, Potables and Spices are necessary goods, as their budget elasticity is positive and below one at the same time. Meat, edible oils, fruits and dried fruits and Sugary products are luxury goods, with income elasticity above one. We find that the remarkable increases in food prices resulted in severe erosion of purchasing power for the Iranian urban households and they need to be compensated on average about 48% of their initial income for the food price changes they faced during the 2004 and 2012. In addition the high share of cereals in year 2012 implies that urban households shift their consumption to cheaper calorie source. This figure is confirmed with the decline in the share of meat, dairy Products, fruits and dried fruits, vegetables and pulses and potables expenditure.

    Although the 2008 food price crisis presumably plunged millions of households into poverty and food insecurity, the real impact of the crisis has rarely been documented using field data. Our objective was to assess the consequences of this crisis for household food insecurity and dietary diversity in urban Burkina Faso. Two cross-sectional surveys were conducted among randomly selected households in Ouagadougou in July 2007 (n = 3017) and July 2008 (n = 3002). At each round, food insecurity assessed by the Household Food Insecurity Access Scale (HFIAS), the Dietary Diversity Score of an index-member of the household (IDDS = number of food groups consumed in the last 24 h), and food expenditure were collected. Food prices of the 17 most frequently consumed food items were recorded throughout the study area. Food prices at local markets increased considerably between 2007 and 2008, especially those of fish (113%), cereals (53%), and vegetable oil (44%), increasing the household monthly food expenditure by 18%. Thirty-three percent of households were food secure in 2007 and 22% in 2008 (P = 0.02). Individuals consumed fewer fruits and vegetables, dairy products, and meat/poultry in 2008 than in 2007 (mean IDDS = 5.7 ± 1.7 food groups in 2007 vs. 5.2 ± 1.5 in 2008; P crisis.

  15. Food Prices and Climate Extremes: A Model of Global Grain Price Variability with Storage

    Science.gov (United States)

    Otto, C.; Schewe, J.; Frieler, K.

    2015-12-01

    Extreme climate events such as droughts, floods, or heat waves affect agricultural production in major cropping regions and therefore impact the world market prices of staple crops. In the last decade, crop prices exhibited two very prominent price peaks in 2007-2008 and 2010-2011, threatening food security especially for poorer countries that are net importers of grain. There is evidence that these spikes in grain prices were at least partly triggered by actual supply shortages and the expectation of bad harvests. However, the response of the market to supply shocks is nonlinear and depends on complex and interlinked processes such as warehousing, speculation, and trade policies. Quantifying the contributions of such different factors to short-term price variability remains difficult, not least because many existing models ignore the role of storage which becomes important on short timescales. This in turn impedes the assessment of future climate change impacts on food prices. Here, we present a simple model of annual world grain prices that integrates grain stocks into the supply and demand functions. This firstly allows us to model explicitly the effect of storage strategies on world market price, and thus, for the first time, to quantify the potential contribution of trade policies to price variability in a simple global framework. Driven only by reported production and by long--term demand trends of the past ca. 40 years, the model reproduces observed variations in both the global storage volume and price of wheat. We demonstrate how recent price peaks can be reproduced by accounting for documented changes in storage strategies and trade policies, contrasting and complementing previous explanations based on different mechanisms such as speculation. Secondly, we show how the integration of storage allows long-term projections of grain price variability under climate change, based on existing crop yield scenarios.

    Full Text Available Abstract Recent years have seen global food prices rise and become more volatile. Price surges in 2008 and 2011 held devastating consequences for hundreds of millions of people and negatively impacted many more. Today one billion people are hungry. The issue is a high priority for many international agencies and national governments. At the Cannes Summit in November 2011, the G20 leaders agreed to implement five objectives aiming to mitigate food price volatility and protect vulnerable persons. To succeed, the global community must now translate these high level policy objectives into practical actions. In this paper, we describe challenges and unresolved dilemmas before the global community in implementing these five objectives. The paper describes recent food price volatility trends and an evaluation of possible causes. Special attention is given to climate change and water scarcity, which have the potential to impact food prices to a much greater extent in coming decades. We conclude the world needs an improved knowledge base and new analytical capabilities, developed in parallel with the implementation of practical policy actions, to manage food price volatility and reduce hunger and malnutrition. This requires major innovations and paradigm shifts by the global community.

  17. WHAT IMPLICATIONS DOES THE WORLD FOOD PRICE RISE HAVE FOR FOOD SECURITY IN BANGLADESH

    Full Text Available Bangladesh has often been regarded as a country whose food security situation is frequently worsened by price rise of essential foodstuffs. Rice has been the most significant cereal food in Bangladesh because it accounts for around 42 percent of per capita daily energy intake. Food price rise has become the most serious concern of majority of the country’s household as price rise becomes the regular phenomenon in the country. One-third of the country’s total population have been living under the poverty line. Regardless of the domestic rice production, Bangladesh imports around three million tonnes of rice every year which constitutes 17 percent of the country’s total import. Therefore, this empirical paper has attempted to explore how Bangladeshi local rice price is being affected by the world rice price, and how rising rice price affects household food security. In doing so, co-integration model and error correction model were applied to weekly rice price data obtained from the on-line database of the Food Policy Monitoring Unit of the Ministry of Food, Government of Bangladesh. The results confirm that world rice price and Bangladesh local market rice price are co-integrated. Although there has not been any immediate impact of world price shock in Bangladesh due to the influence of short term measures taken by the government, there are long term impacts of such price shock. Logit model has been employed to determine the rice price threshold beyond which households become unable to ensure their food security. For this purpose a sample of 80 poor households whose per capita income was less than $1, was surveyed in order to obtain the required data. The results of the logit model suggest that if rice price goes beyond Tk 34 per kilogram, sample poor households become extremely vulnerable in respect of food security. Finally, some recommendations have been made at the end of this paper based on the empirical findings.

    Children in food-insecure households are more likely to experience poorer health function and worse academic achievement. To investigate the relation between economic environmental factors and food insecurity among children, we examined the relation between general and specific food prices (fast food, fruits and vegetables, beverages) and risk of low (LFS) and very low food security (VLFS) status among low-income American households with children. Using information for 27,900 child-year observations from the Early Childhood Longitudinal Study-Kindergarten Class of 1998-1999 linked with food prices obtained from the Cost of Living Data of the Council for Community and Economic Research, formerly known as the American Chamber of Commerce Researchers' Association, fixed effects models were estimated within stratified income groups. Higher overall food prices were associated with increased risk of LFS and VLFS (coefficient = 0.617; P effect on food security status, even when controlling for general food prices. Thus, although food price changes were strongly related to food security status among low-income American households with children, the effects were not uniform across types of food. These relations should be accounted for when implementing policies that change specific food prices.

    Full Text Available Agricultural product is commodity which tends to fluctuate. Price volatility is caused by the change of agricultural production due to climate change as well as pest and disease. Furthermore, it is also caused by the change of agricultural land and high demand of agricultural products on religious holidays. This study was conducted to examine how volatile some of main food commodities in Banyumas Regency. Secondary data analysis method with quantitative approach was used in this research. Time series data of some food commodity prices (rice IR 64, local soybean, maize, chili red peppers, onion and garlic from January 2008 – December 2013 were utilized. The coefficient of variation was calculated to determine price volatility. The result showed that the price of red chili pepper, onion and garlic was tending to volatile. The coefficient of variation ratio of those commodities was about 20% - 35%. While the price of rice, local soybean and maize was stable. The coefficient of variation ratio of those commodities was less than 9%. This study also includes some policies that can be suggested to prevent price volatility.

    Food and beverage price promotions may be potential targets for public health initiatives but have not been well documented. We assessed prevalence and patterns of price promotions for food and beverage products in a nationwide sample of food stores by store type, product package size, and product healthfulness. We also assessed associations of price promotions with community characteristics and product prices. In-store data collected in 2010-2012 from 8959 food stores in 468 communities spanning 46 U.S. states were used. Differences in the prevalence of price promotions were tested across stores types, product varieties, and product package sizes. Multivariable regression analyses examined associations of presence of price promotions with community racial/ethnic and socioeconomic characteristics and with product prices. The prevalence of price promotions across all 44 products sampled was, on average, 13.4% in supermarkets (ranging from 9.1% for fresh fruits and vegetables to 18.2% for sugar-sweetened beverages), 4.5% in grocery stores (ranging from 2.5% for milk to 6.6% for breads and cereals), and 2.6% in limited service stores (ranging from 1.2% for fresh fruits and vegetables to 4.1% for breads and cereals). No differences were observed by community characteristics. Less-healthy versus more-healthy product varieties and larger versus smaller product package sizes generally had a higher prevalence of price promotion, particularly in supermarkets. On average, in supermarkets, price promotions were associated with 15.2% lower prices. The observed patterns of price promotions warrant more attention in public health food environment research and intervention.

    Full Text Available External shocks have significant effects on China's economy, as energy and agriculture food price. In recent years, the increasing of energy price will promote energy efficiency; also increasing prices of agricultural products will impact on production efficiency and economy. In this study, we make a statistical analysis on the impact of energy and agricultural food prices to domestic economy. The result shows that energy price will influence the energy efficiency in the short time, LnEP at lag 1 period increased one percentage can drive LnEE growth by 0.627 percentage, at the same time, agricultural food price will impact on the production efficiency, LnAFP at lag 1 period and the 2 period increased 1 percentage will drive the LnPE increased by 0.245 and 0.016 percentage respectively. Therefore, agricultural food prices have direct mutual promotion effect. Also, there exist at least one direct co-integration relationship between energy price and energy efficiency, which means that there exist a long-term equilibrium relationship between energy price and energy efficiency.

    Full Text Available In this study, we study the impact of money supply changes on food prices by using VAR model. The model set and test are based on the rigorous analysis of co-integration relationship between money supply and food prices, then we make empirical analysis to study the impact of money supply changes to food prices. The result shows that there is a long-term stable relationship between money supply and food price. The money supply and output shocks have different impacts on food prices: the effect of money supply on food price is obvious. Also, the increase of money supply will promote the food price sustained growth in the long time. On the other hand, the increase of GDP will lead to the decline in food prices and make price level tends to be stable.

    Availability and price of healthy foods in food stores has the potential to influence purchasing patterns, dietary intake, and weight status of individuals. This study examined whether demographic factors of the store neighborhood or store size have an impact on the availability and price of healthy foods in sample of grocery stores and supermarkets. The Nutrition Environment Measures Study-Store (NEMS-S) instrument, a standardized observational survey, was utilized to evaluate food stores (N = 42) in a multi-site (Vermont and Arkansas) study in 2008. Census data associated with store census tract (median household income and proportion African-American) were used to characterize store neighborhood and number of cash registers was used to quantify store size. Median household income was significantly associated with the NEMS healthy food availability score (r = 0.36, P store size (r = 0.27, P = 0.09) were significantly related to the Availability score. Larger store size (r = 0.40, P Price scores, indicating more favorable prices for healthier items; neither racial composition nor median household income were significantly related to the Price score (P's > 0.05). Even among supermarkets, healthier foods are less available in certain neighborhoods, although, when available, the quality of healthier options did not differ, suggesting that targeting availability may offer promise for policy initiatives. Furthermore, increasing access to larger stores that can offer lower prices for healthier foods may provide another avenue for enhancing food environments to lower disease risk.

    2016-01-01

    BACKGROUND Although several studies have assessed the price of different food groups in developed countries, there is scarce evidence regarding developing countries. Also, there is no report regarding the price of cardioprotective compared with unhealthy foods. The aim of this study was to determine the trend of food cost across different food groups (cardioprotective vs. unhealthy) and to assess the association between food cost and nutritional quality of foods in Iran. METHODS A list of foods consumed frequently by Iranian population was provided. Nutritional quality of foods was assessed by energy density and nutrient rich foods (NRF) index. Food groups were defined according to the US Department of Agriculture (USDA) MyPlate food groups. The price of food groups was reported as kcal/price and price/serving. RESULTS Although a positive association between different types of nutrient rich foods, nutrient content of foods and food price was observed, there was an inverse relationship between food price and energy density. The kcal/price of "oils" was less than "whole grains" and "refined grains". "Sugar, sweets and beverages" and "beans and legumes" food groups had equal kcal/price media. Among healthy foods for cardiovascular system, nuts had the highest price/serving. On the other hand, among unhealthy foods for cardiovascular system, processed meat had the highest price/serving. The price/serving of healthy oils was similar to saturated and trans fatty acids rich oils. Also, the price/serving of low-fat (healthy) vs. high fat (unhealthy) dairy was not different. Similar finding was observed for white meat vs. red meat. CONCLUSION Our findings revealed that the pattern of food price in Iran is different from developed countries. Also, we found that Iranians can consume a cardioprotective diet without any economic pressure. PMID:28149312

    Infection caused by HIV and malnutrition have a complex interaction and often coexist geographically. Malnutrition has synergistic immune effects and HIV affects nutritional status. HIV care and treatment programs are compelled to confront this dual burden to optimize HIV outcomes. In this article, we review the published literature concerning intervention studies in adults and children and the effect of food prices on HIV treatment programs. While the evidence base is relatively incomplete for specific macronutrient interventions in the context of HIV treatment, it is clear that a new standard of care is needed, guided by experience, rationale, and existing data, in which malnourished patients may easily access nutritional therapies within HIV treatment. From this clinical foundation, we may both treat patients and evaluate novel therapies. Some HIV care and treatment programs provide food-based supplements; however, rising food costs and economic instability may jeopardize the success of these programs. HIV treatment programs may struggle to meet the needs of patients with potential increased rates of malnutrition and food insecurity in the setting of high food prices.

    2016-01-01

    The rapid growth of population in urban areas is jeopardizing the mobility and air quality worldwide. One of the most notable problems arising is that of traffic congestion which in turn affects air pollution. With the advent of technologies able to sense real-time data about cities, and its public distribution for analysis, we are in place to forecast scenarios valuable to ameliorate and control congestion. Here, we propose a local congestion pricing scheme, hotspot-pricing, that surcharges vehicles traversing congested junctions. The proposed tax is computed from the estimation of the evolution of congestion at local level, and the expected response of users to the tax (elasticity). Results on cities' road networks, considering real-traffic data, show that the proposed hotspot-pricing scheme would be more effective than current mechanisms to decongest urban areas, and paves the way towards sustainable congestion in urban areas.

  20. The effects of agricultural trade openness on food price transmission in Latin American countries

    Full Text Available Trade of agricultural commodities has grown significantly in most Latin American countries (LAC over the last two decades. However, after the international food price surges in 2006-08 and 2011-12 concerns about food access of the poor arose. Within a panel framework containing six LAC (Argentina, Brazil, Chile, Colombia, Mexico and Peru, we used a single equation error correction model to identify possible cointegrating relationships between the food consumer price index (CPI and a set of trade related and domestic variables. The main focus of the study was to examine how different levels of trade openness impact international food price transmission to domestic markets. Our results confirm that deeper market integration increases global price transmission elasticities. In other words, more agricultural trade openness proves to elevate food CPIs during global price spikes. Thus, for poor consumers world price shocks can be deteriorating in the short-run and domestic food prices will slowly converge to a higher long-run equilibrium. Especially in increasingly integrated economies, effective policies to buffer food price shocks should be put in place, but must be carefully planned with the required budget readily available. We also found that exchange rate appreciations can buffer price shocks to a certain extent and that monetary policies seem to be an appropriate means for stabilizing food prices to safeguard food access of the poor population.

    2007-04-01

    When adjusting product prices, marketers wish information concerning consumers' price perceptions. The present study aimed to develop an optimal pricing framework for food products by applying Weber's Law and Stevens' Power Law in psychophysics. The first phase attempted to measure the differential thresholds when magnitudes of prices were raised and lowered. The second phase was conducted to establish the psychophysical function representing perceived changes. Analysis showed consumers' differential thresholds were positively correlated with the initial price, consistent with Weber's Law. Further, participants' perceived change differed for increased and decreased prices. Products were perceived as cheaper only when medium-and low-priced products dropped dramatically in price. However, small reductions for the high-priced products were perceived as cheaper. Regardless of price changes, participants perceived products were more expensive when prices dropped by a small

    Yoo, E.-H.; Kyriakidis, P. C.

    2009-12-01

    This paper proposes a geostatistical hedonic price model in which the effects of location on house values are explicitly modeled. The proposed geostatistical approach, namely area-to-point Kriging with External Drift (A2PKED), can take into account spatial dependence and spatial heteroskedasticity, if they exist. Furthermore, this approach has significant implications in situations where exhaustive area-averaged housing price data are available in addition to a subset of individual housing price data. In the case study, we demonstrate that A2PKED substantially improves the quality of predictions using apartment sale transaction records that occurred in Seoul, South Korea, during 2003. The improvement is illustrated via a comparative analysis, where predicted values obtained from different models, including two traditional regression-based hedonic models and a point-support geostatistical model, are compared to those obtained from the A2PKED model.

  8. UPDATE February 2012 - The Food Crises: Predictive validation of a quantitative model of food prices including speculators and ethanol conversion

    CERN Document Server

    Lagi, Marco; Bertrand, Karla Z; Bar-Yam, Yaneer

    2012-01-01

    Increases in global food prices have led to widespread hunger and social unrest---and an imperative to understand their causes. In a previous paper published in September 2011, we constructed for the first time a dynamic model that quantitatively agreed with food prices. Specifically, the model fit the FAO Food Price Index time series from January 2004 to March 2011, inclusive. The results showed that the dominant causes of price increases during this period were investor speculation and ethanol conversion. The model included investor trend following as well as shifting between commodities, equities and bonds to take advantage of increased expected returns. Here, we extend the food prices model to January 2012, without modifying the model but simply continuing its dynamics. The agreement is still precise, validating both the descriptive and predictive abilities of the analysis. Policy actions are needed to avoid a third speculative bubble that would cause prices to rise above recent peaks by the end of 2012.

    Full Text Available Most governments in Africa implement policies aiming to stabilize the prices of staple foods, which often include building up grain reserves, besides other trade measures insulating their domestic market from the world market. The mechanism should ideally work as follows, grains should be bought and stored from areas, during the surplus seasons (after harvest so as to assure fair prices to producers and should be distributed during deficit seasons, in deficit areas besides in cases of emergencies. However, ideal approaches are not necessarily followed in many developing countries due to different constraints and situations. The Strategic Reserve Corporation (SRC is an institution that is established ten years ago to play such a role in Sudan. This paper tries to assess the performance of the SRC against the overall goals and to study the related obstacles if any. We use a sample of 112 respondents from the SRC staff, related and grain farmers as our data source. Results of the research revealed numerous financial and administrative constraints that obstruct SRC from playing the intended role, which need to be considered so as to contribute to price stability and food security in Sudan.

    Prices of four low fat foods were reduced about 25% and prices of three high fat foods were increased about 10% to determine the impact on food purchases in a Midwestern suburban high school cafeteria to explore the impact of price on purchases. Low fat foods averaged about 13% of total sales. Sensitivity analysis was used to estimate that low fat foods would probably have averaged about 9% of total sales without the reduced price.

    Introduction A food allergy is a group of symptoms occurring in the organism and resulting from consuming some food, where the problems are conditioned by immunological mechanisms. The symptoms may become apparent first in adulthood and they may be an initial manifestation of a latent allergy. Typical symptoms of a food allergy occur in different organs, thus not only in the digestive system, but also in the skin, respiratory system and circulatory system. Aim To assess the frequency of food allergy onset in rural areas of the Lublin region as well as to determine which factors induce such allergies. Material and methods A survey was conducted, involving the participation of 340 inhabitants of rural areas. The study monitored the knowledge and situation of the disease, concerning allergens, allergy symptoms, methods of treatment and opinions regarding such treatment. Results The analysis focused on 124 people with diagnosed allergies. Conclusions Introducing a diet did not result in a statistically significant difference regarding elimination of the symptoms, as compared to the patients who did not follow any diet. On the other hand, pharmacological treatment causes statistically worse results than using other methods or not being treated at all. The patients in whom allergy symptoms disappeared were more convinced about the positive character of their diet than those in whom the symptoms were not eliminated. The age when the allergy becomes evident does not affect its duration, yet it matters as to the time of its later elimination. The more symptoms were experienced by a patient, the longer the duration of the allergy was. PMID:27605899

  16. The Effect of Food Prices on Inflation in the Republic of Serbia

    2015-05-01

    Full Text Available In the Republic of Serbia, food accounts for a significant share in the consumer price index through which the inflation is statistically expressed. Therefore, in considerations of the basic factors of increase in the general price level, a special emphasis is placed on the specific features of the market of agricultural-food products. The aim of this research is to peruse the effect of the characteristics of the food market in Serbia on the inflation rate. High volatility of food prices is present because of the instability of this market, mainly due to seasonal fluctuations of supply and the effect of natural factors. Bearing in mind that the increase in food prices is the main determinant of the increase in the inflation rate, the indirect state control is very important so as to maintain price stability. Special importance is attached to the following instruments of economic policy: commodity reserves, storage policy, and fiscal and foreign trade policy.

    Full Text Available The impact of resources on social unrest is of increasing interest to political leaders, business and civil society. Recent events have highlighted that (lack of access to critical resources, including food, energy and water, can, in certain circumstances, lead to violent demonstrations. In this paper, we assess a number of political fragility indices to see whether they are good indicators of propensity to food riots. We found that the most accurate is the Political Instability and Absence of Violence Indicator of the Worldwide Governance Indicators by the World Bank. We compute a likelihood of experiencing a food riot for each quartile of this index. We found that the self-sufficiency of food does not seem to affect the likelihood of the occurrence of food riots, but that the level of political stability of a country does have a role. In addition, we identify a monthly and annual threshold for the Food and Agriculture Organisation Food Price Index, above which food riots in fragile states are more likely to occur.

    2016-09-01

    A propitiously timed household survey carried out in Mozambique over the period 2008/2009 permits us to study the relationship between shifts in food prices and child nutrition status in a low income setting. We focus on weight-for-height and weight-for-age in different survey quarters characterized by very different food price inflation rates. Using propensity score matching techniques, we find that these nutrition measures, which are sensitive in the short run, improve significantly in the fourth quarter of the survey, when the inflation rate for basic food products is low, compared to the first semester or three quarters, when food price inflation was generally high. The prevalence of underweight, in particular, falls by about 40 percent. We conclude that the best available evidence points to food penury, driven by the food and fuel price crisis combined with a short agricultural production year, as substantially increasing malnutrition amongst under-five children in Mozambique.

    The growth of corn-based ethanol production and soybean-based bio-diesel production following the increase in the oil prices have significantly affect the world agricultural grain productions and its prices. The main purpose of this paper is to investigate the relationships between the crude oil price and the global grain prices for corn, soybean, and wheat. The empirical results show that the change in each grain price is significantly influenced by the changes in the crude oil price and other grain prices during the period extending from the 3rd week in 2005 to the 20th week in 2008 which implies that grain commodities are competing with the derived demand for bio-fuels by using soybean or corn to produce ethanol or bio-diesel during the period of higher crude oil prices in these recent years. The subsidy policies in relation to the bio-fuel industries in some nations engaging in bio-fuel production should be considered to avoid the consequences resulting from high oil prices. (author)

    Fast food consumption is a dietary factor associated with higher prevalence of childhood obesity in the United States. The association between food prices and consumption of fast food among 5th and 8th graders was examined using individual-level random effects models utilizing consumption data from the Early Childhood Longitudinal Study, Kindergarten Class of 1998-99 (ECLS-K), price data from American Chamber of Commerce Researchers Association (ACCRA), and contextual outlet density data from Dun and Bradstreet (D&B). The results found that contextual factors including the price of fast food, median household income, and fast food restaurant outlet densities were significantly associated with fast food consumption patterns among this age group. Overall, a 10% increase in the price of fast food was associated with 5.7% lower frequency of weekly fast food consumption. These results suggest that public health policy pricing instruments such as taxes may be effective in reducing consumption of energy-dense foods and possibly reducing the prevalence of overweight and obesity among US children and young adolescents.

  9. Speculation on commodities futures markets and destabilization of global food prices: exploring the connections.

    Ghosh, Jayati; Heintz, James; Pollin, Robert

    2012-01-01

    In December 2010, the United Nations Food and Agriculture Organization's Food Price Index surpassed its previous peak of June 2008, and prices remained at this level through September 2011. This pattern is creating justified fears of a renewal or intensification of the global food crisis. This paper reviews arguments and evidence to inform debates on how to regulate commodity futures markets in the face of such price volatility and sustained high prices. We focus on the relationship between market liquidity and price patterns in asset markets in general and in commodities futures markets in particular, as well as the relationship between spot and futures market prices for food. We find strong evidence supporting the need to limit huge increases in trading volume on futures markets through regulations. We find that arguments opposing regulation are not supported. We find no support for the claim that liquidity in futures markets stabilizes prices at "fundamental" values or that spot market prices are free of any significant influence from futures markets. Given these results, the most appropriate position for regulators is precautionary: they should enact and enforce policies capable of effectively dampening excessive speculative trading on the commodities markets for food.

    World food prices have increased dramatically in recent years. We use panel data from 2006 to examine the impact of these increases on the consumption and nutrition of poor households in two Chinese provinces. We find that households in Hunan suffered no nutrition declines. Households in Gansu experienced a small decline in calories, though the decline is on par with usual seasonal effects. The overall nutritional impact of the world price increase was small because households were able to substitute to cheaper foods and because the domestic prices of staple foods remained low due to government intervention in grain markets.

  12. Medium- to long-run implications of high food prices for global nutrition.

    Science.gov (United States)

    Webb, Patrick

    2010-01-01

    The combined food, fuel, and financial crises of 2007-2009 had severe and widespread negative impacts around the world. Two key questions challenging governments were: how long would the high prices last and with what effects on food security and nutrition over the longer run? This paper considers the drivers of the crisis and explores if, unlike past shocks, the recent price increases reflect structural changes in food price formation that will have lasting global implications. New cross-commodity relationships allowed prices to spike, although there was no shortage of food at the global level nor indeed a significant downturn in recent yields. Yet recent record levels of farm production were also mirrored by growing numbers of people chronically undernourished and/or micronutrient deficient. The gap between supply and need was underpinned by growing urban demand, consumption of processed and higher-value foods (including meat), biofuel policy, and purchasing power erosion, but also by short-term market-distorting policies implemented by governments responding to perceived shortages of food. Thus, the impact of future food price crises will depend largely on what policymakers chose to do in response to the peaks and what they do not do during the troughs. Appropriate investments are urgently needed not just in smallholder developing country agriculture, but in effective food policies and targeted programming that can reverse the recent negative trends in nutrition and that support access globally to improved diet quality as well as food quantity.

    2006-09-01

    The aim of this study was to know the price changes of foods and nutriments in México during the last three decades. To this end, two sets of data were analyzed: the National Consumer Prices Index for 1973 to 2003, and quotations of food prices for 1990, 1995, 2000 and 2004. Cost estimates were calculated for 100 kcal, 10 g of saturated fat, 100 mg of cholesterol, 10 g of fiber and 1 mg of iron. Regression models were used to analyze the association between nutrient and energy's costs and energetic and nutrimental densities. Our results lead to infer that that in M6xico, the structure of foods prices differed between the eighties and the nineties decades. In the former, vegetables and corn and wheat derived foods had the lowest price increment, whereas their price had the largest increment in the following decade. On the other hand, the prices of fresh meat of cattle and pig, and of fish and seafood rose during the eighties but became cheaper during the nineties. The differences in prices of the meat are inversely related to their energy density and nutrimental value: lean meat became more expensive that those with more fat (i.e., more energy and cholesterol). Canned fish (tuna and sardine), eggs and poultry became cheaper at the turn of the eighties. The prices of the majority of oils and fats have increased less than the inflation of the group of food. Processed and industrialized foods became cheaper than the fresh ones. The energy density of the foods is negatively correlated to their cost. The implications of our results are discussed in terms of public policies.

    2013-12-01

    The public health literature suggests that the cheapness of energy-dense foods is driving the obesity epidemic. We examined food purchases in low-income families and its relationship to the price of food and availability of funds. In-depth interviews were conducted with 22 parents with children less than 15 years of age whose major source of income was a government pension. A photo taxonomy, where participants sorted 50 photos of commonly purchased foods, was used to explore food choice. The most common food groupings used by the participants were: basic, emergency, treat and comfort. The process of food purchase was described by participants as weighing up the attributes of a food in relation to price and money available. Shoppers nominated the basic unit of measurement as quantity per unit price and the heuristic for food choice when shopping as determining "value for money" in a process of triage relating to food purchase decisions. Participants stated satiation of hunger to be the most common "value" relative to price. Given that the foods nominated as filling tended to be carbohydrate-rich staples, we suggest that public health initiatives need to acknowledge this triage process and shape interventions to promote nutrition over satiation.

    Full Text Available The study of alcohol abuse is relatively new in Brazil. Government estimates suggest that 11.2% of the Brazilian population is alcohol dependent. Problems associated with alcohol dependence include domestic violence, increased risk of traffic accidents, poor self-esteem and weak academic performance. A factor known to correlate with alcohol abuse in 12-17 year olds is to have the money necessary to purchase alcoholic beverages. No data is available, however, on the price of alcoholic beverages. The objective of the present study was to provide data on price and to compare the price of alcoholic beverages to basic food items in the Brazilian diet. We also had interest in studying a population in the northeast region of Brazil. This region is the poorest in Brazil, has the highest percentage of alcohol dependency and is seldom the focus of research on dependency. We report that the prices of many alcoholic beverages are less than the price of basic food items. Prices of alcoholic beverages including beer, wine and spirits were compared to the prices of select food items as represented in the Food Pyramid. Food items were selected from the categories of Grain, Dairy, Fruit, Meat and Vegetable. Data was gathered from 32 supermarkets in 8 cities in the northeast state of Paraiba. The price of alcohol is generally less expensive than most basic food group items, especially brands of cachaça (a spirit distilled from sugar cane and beer. Data on price should be considered in any alcohol dependency program in Brazil.

    Full Text Available BACKGROUND: Targeted food pricing policies may improve population diets. To assess their effects on inequalities, it is important to determine responsiveness to price changes across income levels and ethnic groups. OBJECTIVE: Our goal was to estimate price elasticity (PE values for major commonly consumed food groups in New Zealand, by income and ethnicity. PE values represent percentage change in demand associated with 1% change in price of that good (own-PE or another good (cross-PE. DESIGN: We used food expenditure data from national household economic surveys in 2007/08 and 2009/10 and Food Price Index data from 2007 and 2010. Adopting an Almost Ideal Demand System approach, own-PE and cross-PE estimates were derived for 24 food categories, household income quintiles, and two ethnic groups (Māori and non-Māori. RESULTS: Own-PE estimates (with two exceptions ranged from -0.44 to -1.78. Cross-PE estimates were generally small; only 31% of absolute values were greater than 0.10. Excluding the outlier 'energy drinks', nine of 23 food groups had significantly stronger own-PEs for the lowest versus highest income quintiles (average regression-based difference across food groups -0.30 (95% CI -0.62 to 0.02. Six own-PEs were significantly stronger among Māori; the average difference for Māori: non-Māori across food groups was -0.26 (95% CI -0.52 to 0.00. CONCLUSIONS: Food pricing policies have potential to improve population diets. The greater sensitivity of low-income households and Māori to price changes suggests the beneficial effects of such policies on health would be greatest for these groups.

    2014-01-01

    Full Text Available There is persistent instability of consumer prices for most agricultural commodities in Nigeria. This is occasioned by factors such as season, input price changes, production and marketing technologies and consumer taste, among others. The market price variations often affect the level of consumer demand and food security status of the households. This study therefore examined the synergy between the agricultural commodity prices, consumer demand and food security status of the consuming households in Nigeria. A total of 360 foodgrains consumers were randomly sampled for this study from the 6 geo-political zones in the country. Results indicated that despite the various policies on agricultural prices, the market prices of foodgrains remain unstable. Specifically, the level of consumer demand and satisfaction got reduced while a large proportion of the consumers were food insecure. Major factors that are responsible for unstable consumer demand and household insecurity in the consumption of foodgrains among Nigerians include insufficient household income, increasing household size, consumer preference, market price and lack of standard measurement. With increased discipline in the style of implementation of the various price policies on agricultural commodities, it is hoped that the level of consumer demand and foodgrains security status of Nigerians will improve.

  20. Interdependencies between Biofuel, Fuel and Food Prices: The Case of the Brazilian Ethanol Market

    Directory of Open Access Journals (Sweden)

    Deborah Bentivoglio

    2016-06-01

    Full Text Available Brazil is currently the world’s largest sugar producer and exporter, as well as the world’s largest producer and consumer of sugarcane ethanol as a transportation fuel. The growth of this market originates from a combination of government policies and technological change, in both the sugarcane ethanol processing sector and the manufacture of flex-fuel vehicles. In recent years however, ethanol production has been questioned due to its possible impact on food prices. The present paper aims to explore the impact of Brazilian ethanol prices on sugar and gasoline prices. The relationships between a times series of these prices are investigated using a Vector Error Correction Model (VECM, supported by Granger Causality tests. In addition, Impulse Response Functions (IRFs and Forecast Error Variance Decompositions (FEVD are computed in order to investigate the dynamic interrelationships within these series. Our results suggest that ethanol prices are affected by both food and fuel prices, but that there is no strong evidence that changes in ethanol prices have an impact on food prices.

  1. Distributional impacts of the 2008 global food price spike in Vietnam

    DEFF Research Database (Denmark)

    McKay, Andy; Tarp, Finn

    Agriculture and food cultivation production remains a key sector in the Vietnamese economy in terms of productive activities, income generation, and national export earnings. Higher world market prices should therefore in principle have a beneficial impact on rural farmers. This is based however...... on the assumption that world prices are transmitted and that farmers have the capacity to respond. In addition, many poorer farm households may be net consumers. Using data from the Vietnam Access to Resources Household Survey (VARHS) and the Vietnam Household Living Standard Survey (VHLSS) combined with available...... macro-data, this paper investigates how global price changes appear to have impacted on rural welfare in Vietnam during 2006-12. In this paper we study the case of rice in Vietnam, in the context of the 2008 food price spike. We analyse the responses of domestic producer and consumer prices, and discuss...

  3. Maternal and young child nutrition adversely affected by external shocks such as increasing global food prices.

    2010-01-01

    Rising food prices, resulting from the ongoing global economic crisis, fuel price volatility, and climate change, have an adverse impact upon the poor, especially those in food-importing, resource-limited countries. The conventional approach by large organizations has been to advocate for increased staple crop yields of mainly cereals. High food prices are predicted to continue to at least 2015. Past shocks and their known impacts upon nutrition were reviewed. Price instability and increases have long been an existing global problem, which has been exacerbated by recent macroeconomic shocks such as acute emergencies due to war and civil strife, acute climatic events, increase in food prices, fuel price volatility, dysfunction of the global financial systems, long-term climate change, and the emergence of failed states. The FAO estimated that there were 815 million "hungry" people in 2006, with a now additional 75-135 million with increased vulnerability, and currently it is estimated that there are one billion people at risk of food insecurity. The shocks initially compromise maternal and child nutrition, mainly through a reduction in dietary quality and an increase in micronutrient deficiencies and concomitant increases in infectious disease morbidity and mortality. A further reduction in the quantity of diet may follow with greater underweight and wasting. Recent macroeconomic shocks have greatly increased the number of people who are vulnerable to hunger in developing countries. Nutritional surveillance systems need to be strengthened and expanded to inform policy decisions.

  4. Afforestation to mitigate climate change: impacts on food prices under consideration of albedo effects

    Ambitious climate targets, such as the 2 °C target, are likely to require the removal of carbon dioxide from the atmosphere. Afforestation is one such mitigation option but could, through the competition for land, also lead to food prices hikes. In addition, afforestation often decreases land-surface albedo and the amount of short-wave radiation reflected back to space, which results in a warming effect. In particular in the boreal zone, such biophysical warming effects following from afforestation are estimated to offset the cooling effect from carbon sequestration. We assessed the food price response of afforestation, and considered the albedo effect with scenarios in which afforestation was restricted to certain latitudinal zones. In our study, afforestation was incentivized by a globally uniform reward for carbon uptake in the terrestrial biosphere. This resulted in large-scale afforestation (2580 Mha globally) and substantial carbon sequestration (860 GtCO2) up to the end of the century. However, it was also associated with an increase in food prices of about 80% by 2050 and a more than fourfold increase by 2100. When afforestation was restricted to the tropics the food price response was substantially reduced, while still almost 60% cumulative carbon sequestration was achieved. In the medium term, the increase in prices was then lower than the increase in income underlying our scenario projections. Moreover, our results indicate that more liberalised trade in agricultural commodities could buffer the food price increases following from afforestation in tropical regions.

  5. An agent-based approach to modelling the effects of extreme events on global food prices

    Science.gov (United States)

    Schewe, Jacob; Otto, Christian; Frieler, Katja

    2015-04-01

    Extreme climate events such as droughts or heat waves affect agricultural production in major food producing regions and therefore can influence the price of staple foods on the world market. There is evidence that recent dramatic spikes in grain prices were at least partly triggered by actual and/or expected supply shortages. The reaction of the market to supply changes is however highly nonlinear and depends on complex and interlinked processes such as warehousing, speculation, and export restrictions. Here we present for the first time an agent-based modelling framework that accounts, in simplified terms, for these processes and allows to estimate the reaction of world food prices to supply shocks on a short (monthly) timescale. We test the basic model using observed historical supply, demand, and price data of wheat as a major food grain. Further, we illustrate how the model can be used in conjunction with biophysical crop models to assess the effect of future changes in extreme event regimes on the volatility of food prices. In particular, the explicit representation of storage dynamics makes it possible to investigate the potentially nonlinear interaction between simultaneous extreme events in different food producing regions, or between several consecutive events in the same region, which may both occur more frequently under future global warming.

    2014-11-01

    Full Text Available In the food industry, price is an influential and a key factor in product brand positioning. This importance is even greater as the market analyzed is that of Romania. Since it is at the beginning of its relations with foreign markets compared to other countries, whether they are in the European Union or in Northern America, until a few years ago by Romanian consumers used to choose food products only based on the price and generally just buy the cheapest product, without taking into account other selection criteria. Now the market has developed, however, and there were many changes in behavior. This paper is a theoretical analysis on the influence of prices in the food market, the evolution of its importance due to the effects of the recession, the repercussions of changes in price and variation in behavior due to promotions. Preliminary results show that price is the main benefit by which consumers position food in their mind and that price promotions have an impact on positioning.

    Full Text Available Fiscal interventions to improve population diet have been recommended for consideration by many organisations including the World Health Organisation and the United Nations and policies such as sugar-sweetened beverage taxes have been implemented at national and sub-national levels. However, concerns have been raised with respect to the differential impact of fiscal interventions on population sub-groups and this remains a barrier to implementation.To examine how personal characteristics (such as socioeconomic status, sex, impulsivity, and income moderate changes in purchases of targeted foods in response to food and beverage price changes in experimental settings.Systematic review.Online databases (PubMed, EMBASE, Web of Science, EconLit and PsycInfo, reference lists of previous reviews, and additional data from study authors.We included randomised controlled trials where food and beverage prices were manipulated and reported differential effects of the intervention on participant sub-groups defined according to personal characteristics.Where possible, we extracted data to enable the calculation of price elasticities for the target foods by personal characteristic.8 studies were included in the review. Across studies, the difference in price elasticity varied from 0.02 to 2.43 between groups within the same study. 11 out of the total of 18 comparisons of own-price elasticity estimates by personal characteristic differed by more than 0.2 between groups. Income related factors were the most commonly considered and there was an indication that own-price elasticity estimates do vary by income but the direction of this effect was not clear.Experimental studies provide an opportunity to examine the differential effects of fiscal measures to improve population diets. Patterns in price sensitivity by personal characteristics are complex. General conclusions pertaining to the effects of personal characteristics on price sensitivity are not supported by

    Unhealthy eating is more prevalent among women and people with a low socioeconomic status. Policies that affect the price of food have been proposed to improve diet quality. The study's objective was to compare the impact of food price policies on the nutritional quality of food baskets chosen by low-income and medium-income women. Experimental economics was used to simulate a fruit and vegetable subsidy and a mixed policy subsidizing healthy products and taxing unhealthy ones. Food classification was based on the Score of Nutritional Adequacy of Individual Foods, Score of Nutrients to Be Limited nutrient profiling system. Low-income (n = 95) and medium-income (n = 33) women selected a daily food basket first at current prices and then at policy prices. Energy density (ED) and the mean adequacy ratio (MAR) were used as nutritional quality indicators. At baseline, low-income women selected less healthy baskets than medium-income women (less fruit and vegetables, more unhealthy products, higher ED, lower MAR). Both policies improved nutritional quality (fruit and vegetable quantities increased, ED decreased, the MAR increased), but the magnitude of the improvement was often lower among low-income women. For instance, ED decreased by 5.3% with the fruit and vegetable subsidy and by 7.3% with the mixed subsidy, whereas decreases of 13.2 and 12.6%, respectively, were recorded for the medium-income group. Finally, both policies improved dietary quality, but they increased socioeconomic inequalities in nutrition.

    2014-04-01

    Full Text Available The world experienced in dramatic price surge of food commodities since mid of 2007 to 2008. It was claimed that the crisis were being mainly for backdrop of global shocks in food and energy price. But how the shocks come to domestic market from external sources is a researchable phenomenon. Surprisingly few attempts have been made to systematically analysis of shock transmission from international to domestic market. The study analyzed the effect of global commodity market factors and domestic exchange rate development on domestic food price in Bangladesh. A bi-variants co-integration approach was applied for the analysis of shock transmission. Finally an error correction model was developed. The overall magnitudes of the pass through suggest that only 46 per cent of the total world shock pass-through in domestic economy.

    The present paper studies the interdependencies between the energy, bioenergy and food prices. We develop a vertically integrated multi-input, multi-output market model with two channels of price transmission: a direct biofuel channel and an indirect input channel. We test the theoretical hypothesis by applying time-series analytical mechanisms to nine major traded agricultural commodity prices, including corn, wheat, rice, sugar, soybeans, cotton, banana, sorghum and tea, along with one weighted average world crude oil price. The data consists of 783 weekly observations extending from January 1994 to December 2008. The empirical findings confirm the theoretical hypothesis that the prices for crude oil and agricultural commodities are interdependent including also commodities not directly used in bioenergy production: an increase in oil price by 1 $/barrel increases the agricultural commodity prices between 0.10 $/tonne and 1.80 $/tonne. Contrary to the theoretical predictions, the indirect input channel of price transmission is found to be small and statistically insignificant. (author)

    Legislation in NYC requires chain restaurants to post calorie information on menu boards in an effort to help consumers make more informed decisions about food and beverage items they are purchasing. While this is a step in the right direction in light of the current obesity epidemic, there are other issues that warrant attention in a fast food setting, namely the pricing of healthy food options, promotional strategies, and access to comprehensive nutrition information. This study focused on a popular fast-food chain in NYC. The study's aims were threefold: (1) to determine the cost differential between the healthiest meal item on the chain's general menu and meal items available specifically on a reduced cost menu for one dollar (US$1.00); (2) to identify and describe the promotions advertised in the windows of these restaurants, as well as the nutrition content of promoted items; and (3) to ascertain availability of comprehensive nutrition information to consumers within the restaurants. We found the healthiest meal item to be significantly higher in price than less nutritious meal items available for $1.00 (t=146.9, ppromotions generally advertised less healthful menu items, which may aid in priming customers to purchase these versus more healthful options. Comprehensive nutrition information beyond calorie counts was not readily accessible prior to purchasing. In addition to improving access to comprehensive nutrition information, advertising more of and lowering the prices of nutritious options may encourage consumers to purchase healthier foods in a fast food setting. Additional research in this area is needed in other geographic locations and restaurant chains.

    2013-10-16

    There is an unresolved debate about the potential effects of financial speculation on food prices and price volatility. Germany's largest financial institution and leading global investment bank recently decided to continue investing in agricultural commodities, stating that there is little empirical evidence to support the notion that the growth of agricultural-based financial products has caused price increases or volatility. The statement is supported by a recently published literature review, which concludes that financial speculation does not have an adverse effect on the functioning of the agricultural commodities market. As public health professionals concerned with global food insecurity, we have appraised the methodological quality of the review using a validated and reliable appraisal tool. The appraisal revealed major shortcomings in the methodological quality of the review. These were particularly related to intransparencies in the search strategy and in the selection/presentation of studies and findings; the neglect of the possibility of publication bias; a lack of objective or rigorous criteria for assessing the scientific quality of included studies and for the formulation of conclusions. Based on the results of our appraisal, we conclude that it is not justified to reject the hypothesis that financial speculation might have adverse effects on food prices/price volatility. We hope to initiate reflections about scientific standards beyond the boundaries of disciplines and call for high quality, rigorous systematic reviews on the effects of financial speculation on food prices or price volatility.

  1. Examining the changing profile of undernutrition in the context of food price rises and greater inequality.

    Nandy, Shailen; Daoud, Adel; Gordon, David

    2016-01-01

    This paper examines how the profile of undernutrition among children in two African countries (Ethiopia and Nigeria) changed over the period of the 2007/08 food, fuel and financial crisis. Using the Composite Index of Anthropometric Failure (CIAF), an indicator which allows for a comprehensive assessment of undernutrition in young children, we examine what changes occurred in the composition of undernutrition, and how these changes were distributed amongst children in different socio-economic groups. This is important as certain combinations of anthropometric failure (AF), especially the experience of multiple failures (dual and triple combinations of AF) are associated with higher morbidity and mortality risks, and are also related to poverty. Our hypothesis is that increases in food prices during the crisis contributed to an increase in inequality, which may have resulted in concurrent increases in the prevalence of more damaging forms of undernutrition amongst poorer children. While both countries witnessed large increases in food prices, the effects were quite different. Ethiopia managed reduce the prevalence of multiple anthropometric failure between 2005 and 2011 across most groups and regions. By contrast, in Nigeria prevalence increased between 2008 and 2013, and particularly so in the poorer, northern states. The countries studied applied quite different policies in response to food price increases, with the results from Ethiopia demonstrating that protectionist public health and nutrition interventions can mitigate the impacts of price increases on poor children.

    Full Text Available It is widely recognized that inflation as a monetary phenomenon is determined by money supply changes. In the short run, however, several factors may lead to inflation rate differentials among different regions in the same country or among different countries in a monetary union. This paper examines the mean reversion attitude of food price inflation rates in the Euro zone, borrowing the concepts and developments from the recent growth literature and using panel unit root tests. Additionally, in order to capture sufficiently the evolving distributional dynamics, nonparametric econometric methods are also implemented. Finally, the comovement of the inflation rates among different food subgroups is also explored. The data consist of monthly observations of the EU harmonized consumer price indices of food and three different food subgroups (meat, bread and cereals, and vegetables for the 12 older member states of the Euro zone, covering the period from 1997 to 2010. The results do not fully support the hypothesis of the food price inflation rates convergence for the whole period under investigation. Mean reversion shows up in different time periods and in different food categories. Moreover, the analysis of distribution dynamics sheds light to different aspects of convergence and highlights processes like club formation and polarization.

    A global economic and financial crisis is engulfing the developing world, coming on top of high food and fuel prices. This paper assesses the impact of the crises on food consumption, nutrition, and health. Several methods were applied, including risk analysis using the cost of the food basket, assessment surveys, simulations, regression analysis using a food consumption score (FCS), reflecting diet frequency and diversity, and a review of the impact of such dietary changes on nutritional status and health. The cost of the food basket increased in several countries, forcing households to reduce quality and quantity of food consumed. The FCS, which is a measure of diet diversity, is negatively correlated with food prices. Simulations show that energy consumption declined during 2006-2010 in nearly all developing regions, resulting potentially in an additional 457 million people (of 4.5 billion) at risk of being hungry and many more unable to afford the dietary quality required to perform, develop, and grow well. As a result of the crises, large numbers of vulnerable households have reduced the quality and quantity of foods they consume and are at risk of increased malnutrition. Population groups most affected are those with the highest requirements, including young children, pregnant and lactating women, and the chronically ill (particularly people with HIV/AIDS and tuberculosis). Because undernutrition during the first 2 y of life has life-long consequences, even short-term price rises will have long-term effects. Thus, measures to mitigate the impact of the crises are urgently required.

  6. The Retail Chain Design for Perishable Food: The Case of Price Strategy and Shelf Space Allocation

    Full Text Available Managing perishable food in a retail store is quite difficult because of the product’s short lifetime and deterioration. Many elements, such as price, shelf space allocation, and quality, which can affect the consumption rate, should be taken into account when the perishable food retail chain is designed. The modern tracking technologies provide good opportunities to improve the management of the perishable food retail chain. In this research, we develop a mathematical model for a single-item retail chain and determine the pricing strategy, shelf space allocation, and order quantity to maximize the retailer’s total profit with the application of tracking technologies. Then the single-item retail chain is extended into a multi-item one with a shelf space capacity and a simple algorithm is developed to find the optimal allocation of shelf space among these items. Finally, numerical experiments and real-life examples are conducted to illustrate the proposed models.

    In many poor countries, the recent increases in prices of staple foods have raised the real incomes of those selling food, many of whom are relatively poor, while hurting net food consumers, many of whom are also relatively poor. The impacts on poverty will certainly be very diverse, but the average impact on poverty depends upon the balance between these two effects, and can only be determined by looking at real-world data.

    The projected rise in food-related greenhouse gas emissions could seriously impede efforts to limit global warming to acceptable levels. Despite that, food production and consumption have long been excluded from climate policies, in part due to concerns about the potential impact on food security. Using a coupled agriculture and health modelling framework, we show that the global climate change mitigation potential of emissions pricing of food commodities could be substantial, and that levying greenhouse gas taxes on food commodities could, if appropriately designed, be a health-promoting climate policy in high-income countries, as well as in most low- and middle-income countries. Sparing food groups known to be beneficial for health from taxation, selectively compensating for income losses associated with tax-related price increases, and using a portion of tax revenues for health promotion are potential policy options that could help avert most of the negative health impacts experienced by vulnerable groups, whilst still promoting changes towards diets which are more environmentally sustainable.

    The land use sector of agriculture, forestry, and other land use (AFOLU) plays a central role in ambitious climate change mitigation efforts. Yet, mitigation policies in agriculture may be in conflict with food security related targets. Using a global agro-economic model, we analyze the impacts on food prices under mitigation policies targeting either incentives for producers (e.g., through taxes) or consumer preferences (e.g., through education programs). Despite having a similar reduction potential of 43-44% in 2100, the two types of policy instruments result in opposite outcomes for food prices. Incentive-based mitigation, such as protecting carbon-rich forests or adopting low-emission production techniques, increase land scarcity and production costs and thereby food prices. Preference-based mitigation, such as reduced household waste or lower consumption of animal-based products, decreases land scarcity, prevents emissions leakage, and concentrates production on the most productive sites and consequently lowers food prices. Whereas agricultural emissions are further abated in the combination of these mitigation measures, the synergy of strategies fails to substantially lower food prices. Additionally, we demonstrate that the efficiency of agricultural emission abatement is stable across a range of greenhouse-gas (GHG) tax levels, while resulting food prices exhibit a disproportionally larger spread.

    2008-12-01

    The recent massive increase in food and energy prices in the past five years, coupled with the awareness of the long term challenges of climate change to small holder agriculture in Africa has brought the issue of food security for the world's poorest people to the forefront once again. Asymmetric and limited integration of local commodity markets in West Africa highlights the weak position of Africa's rural countries in the face of climate change and demographic expansion. This paper will describe the functioning of local informal food markets in West African over the past twenty years and evaluate the impact of their limited integration with each other and with global commodity markets. Satellite remote sensing of vegetation has been used as a proxy for agricultural production in economic models to improve prediction of large swings in prices from year to year due to differences in supply. As demand increases, improvements in market functioning will be necessary to counter likely increases in production variability. Increasing Africa's stability in the face of climate change will require investment in agricultural production and transportation infrastructure in order to ensure an affordable flow of food to people in these extremely poor, landlocked countries.

    Nutrient profiling ranks foods based on their nutrient content. They may help identify foods with a good nutritional quality for their price. This hypothesis was tested using diet modeling with linear programming. Analyses were undertaken using food intake data from the nationally representative French INCA (enquête Individuelle et Nationale sur les Consommations Alimentaires) survey and its associated food composition and price database. For each food, a nutrient profile score was defined as the ratio between the previously published nutrient density score (NDS) and the limited nutrient score (LIM); a nutritional quality for price indicator was developed and calculated from the relationship between its NDS:LIM and energy cost (in euro/100 kcal). We developed linear programming models to design diets that fulfilled increasing levels of nutritional constraints at a minimal cost. The median NDS:LIM values of foods selected in modeled diets increased as the levels of nutritional constraints increased (P = 0.005). In addition, the proportion of foods with a good nutritional quality for price indicator was higher (P quality for their price. Linear programming is a useful tool for testing nutrient profiling systems and validating the concept of nutrient profiling.

    2008-12-01

    Full Text Available Abstract Background Although point-of-purchase calorie labeling at restaurants has been proposed as a strategy for improving consumer food choices, a limited number of studies have evaluated this approach. Likewise, little research has been conducted to evaluate the influence of value size pricing on restaurant meal choices. Methods To examine the effect of point-of-purchase calorie information and value size pricing on fast food meal choices a randomized 2 × 2 factorial experiment was conducted in which participants ordered a fast food meal from one of four menus that varied with respect to whether calorie information was provided and whether value size pricing was used. Study participants included 594 adolescents and adults who regularly ate at fast food restaurants. Study staff recorded the foods ordered and consumed by each participant. Participants also completed surveys to assess attitudes, beliefs and practices related to fast food and nutrition. Results No significant differences in the energy composition of meals ordered or eaten were found between menu conditions. The average energy content of meals ordered by those randomized to a menu that included calorie information and did not include value size pricing was 842 kcals compared with 827 kcals for those who ordered their meal from a menu that did not include calorie information but had value size pricing (control menu. Results were similar in most analyses conducted stratified by factors such as age, race and education level. Conclusion Additional research is needed to better evaluate the effects of calorie labeling and value size pricing on fast food meal choices. Studies in which participants are repeatedly exposed to these factors are needed since long term exposure may be required for behavior change.

  17. Impact of the economic crisis and increase in food prices on child mortality: exploring nutritional pathways.

    2010-01-01

    The current economic crisis and food price increase may have a widespread impact on the nutritional and health status of populations, especially in the developing world. Gains in child survival over the past few decades are likely to be threatened and millennium development goals will be harder to achieve. Beyond starvation, which is one of the causes of death in famine situations, there are numerous nutritional pathways by which childhood mortality can increase. These include increases in childhood wasting and stunting, intrauterine growth restriction, and micronutrient deficiencies such as that of vitamin A, iron, and zinc when faced with a food crisis and decreased food availability. These pathways are elucidated and described. Although estimates of the impact of the current crisis on child mortality are yet to be made, data from previous economic crises provide evidence of an increase in childhood mortality that we review. The current situation also emphasizes that there are vast segments of the world's population living in a situation of chronic food insecurity that are likely to be disproportionately affected by an economic crisis. Nutritional and health surveillance data are urgently needed in such populations to monitor both the impacts of a crisis and of interventions. Addressing the nutritional needs of children and women in response to the present crisis is urgent. But, ensuring that vulnerable populations are also targeted with known nutritional interventions at all times is likely to have a substantial impact on child mortality.

  19. The market value of cultural heritage in urban areas: an application of spatial hedonic pricing

    2014-01-01

    The current literature often values intangible goods like cultural heritage by applying stated preference methods. In recent years, however, the increasing availability of large databases on real estate transactions and listed prices has opened up new research possibilities and has reduced various existing barriers to applications of conventional (spatial) hedonic analysis to the real estate market. The present paper provides one of the first applications using a spatial autoregressive model to investigate the impact of cultural heritage—in particular, listed buildings and historic-cultural sites (or historic landmarks)—on the value of real estate in cities. In addition, this paper suggests a novel way of specifying the spatial weight matrix—only prices of sold houses influence current price—in identifying the spatial dependency effects between sold properties. The empirical application in the present study concerns the Dutch urban area of Zaanstad, a historic area for which over a long period of more than 20 years detailed information on individual dwellings, and their market prices are available in a GIS context. In this paper, the effect of cultural heritage is analysed in three complementary ways. First, we measure the effect of a listed building on its market price in the relevant area concerned. Secondly, we investigate the value that listed heritage has on nearby property. And finally, we estimate the effect of historic-cultural sites on real estate prices. We find that, to purchase a listed building, buyers are willing to pay an additional 26.9 %, while surrounding houses are worth an extra 0.28 % for each additional listed building within a 50-m radius. Houses sold within a conservation area appear to gain a premium of 26.4 % which confirms the existence of a `historic ensemble' effect.

    European Union Regulation 258/97 defines novel foods as food products and food ingredients that have not been consumed to a significant degree in the European Union before May 1997. However, there are new foods that for some reason are not considered as novel foods, though we think that safety of these products is not always a priori established. We defined a 'grey area' which consists of such foods, and the present paper intends to raise awareness of this 'grey area' of unidentified novel foods. The grey area of novel foods is divided into two categories: (1) food products or ingredients for which the current Regulation leaves too much space for different interpretations and (2) food products or ingredients that are not novel according to the current Regulation, because the current Regulation contains gaps. These categories are illustrated by means of products already on the market in The Netherlands. We found about two dozen examples of products that had not been identified as novel foods according the current Regulation, yet could be considered to be classified as novel foods and hence for which a safety evaluation (toxicological and/or nutritional) would be indicated.

    This paper made a VECM-based research using the data of China and world food price from January 2007 to June 2013 , and found out that china food price and world food price is in a long and stable relationship, that world food price has a greater impact on China food prices than vice versa-when China food prices deviates from the equilibrium price level by interference, it is subject to a force in the same direction to make a big adjustment, but when world food price deviates from the equilibrium price level by interference, it is subject to a reverse force to make a small adjustment-and that the world food price shock is an important factor leading to the domestic food price changes. It recommends monitoring the supply and demand of world food market, increasing investment on China’s grain production and expanding the sources of food import to China so as to prevent food inflation risk in China .%基于2007年1月至2013年6月间国内外食品价格数据,利用VECM模型研究发现:国内外食品价格之间存在长期稳定的关系,国际食品价格对国内食品价格的影响比后者对前者的影响更大;我国食品价格受到干扰偏离均衡价格时,将受到一个同向的调整力,调整幅度较大。而当国际食品价格受到干扰偏离均衡价格时,将受到一个反向的调整力,调整幅度较小;国际食品价格冲击是导致国内食品价格变动的重要因素。可从监测国际食品市场供求关系、加大对粮食生产的投资力度和拓宽我国粮食进口来源渠道等方面制订防范我国食品通胀风险的政策。

    International food prices relatively stable in the first half of 2010, the second half of a comprehensive and rapid rise, enter the price kept rising sharply in 2011. In 2012 because of the severe failure of grain and other food exporters suffered a drought, food prices con-tinue to rise. A weaker dollar and global excess liquidity is a major cause of the food price volatility;In addition, the development of agricul-tural machinery, food production, capital speculation, food export restrictions, and development of biomass energy is also important factor. The next year, the international market of wheat, soybean prices may continue to fall, but the average price of corn will from this year will continue to rise, especially rice prices may hit a record high. Therefore, our country should continue to increase support for major grain-pro-ducing areas, strengthen the development of agricultural mechanization, efforts to prepare for food market regulation and control work, we will continue to improve the grain market monitoring function, establish and improve the grain market risk management mechanism.%2010年上半年国际粮食价格相对稳定、下半年出现全面快速上涨,进入2011年价格仍保持大幅上涨态势。2012年因美国粮食出现严重欠收及其他粮食出口大国遭遇干旱,导致粮食价格持续出现上涨局面。美元贬值和全球流动性过剩是粮食价格波动的主因;此外,农业机械化发展、粮食减产、资本投机、粮食出口限制及发展生物质能源等也是重要因素。未来年度,国际市场小麦、大豆价格可能回落,但玉米价格均值将较2013年会继续上涨,尤其大米价格可能创出新高。为此,我国应继续加大对粮食主产区的支持力度,加大农业机械化的发展步伐,努力作好粮食市场调控工作,继续完善粮食市场监测功能,建立健全粮食市场风险管理机制。

    The 17 Sustainable Development Goals (SDGs) call for a comprehensive new approach to development rooted in planetary boundaries, equity, and inclusivity. The wide scope of the SDGs will necessitate unprecedented integration of siloed policy portfolios to work at international, regional, and national levels toward multiple goals and mitigate the conflicts that arise from competing resource demands. In this analysis, we adopt a comprehensive modeling approach to understand how coherent policy combinations can manage trade-offs among environmental conservation initiatives and food prices. Our scenario results indicate that SDG strategies constructed around Sustainable Consumption and Production policies can minimize problem-shifting, which has long placed global development and conservation agendas at odds. We conclude that Sustainable Consumption and Production policies (goal 12) are most effective at minimizing trade-offs and argue for their centrality to the formulation of coherent SDG strategies. We also find that alternative socioeconomic futures—mainly, population and economic growth pathways—generate smaller impacts on the eventual achievement of land resource–related SDGs than do resource-use and management policies. We expect that this and future systems analyses will allow policy-makers to negotiate trade-offs and exploit synergies as they assemble sustainable development strategies equal in scope to the ambition of the SDGs.

    This research examines the larger-scale associations between obesity and food environments in metropolitan areas in the United States (US). The US Census County Business Patterns dataset for 2011 was used to construct various indices of food environments for selected metropolitan areas. The numbers of employees engaged in supermarkets, convenience stores, full service restaurants, fast food restaurants, and snack/coffee shops were standardised using the location quotients, and factor analysis was used to produce two uncorrelated factors measuring food environments. Data on obesity were obtained from the 2011 Behavioral Risk Factor Surveillance System. Individual level obesity measures were linked to the metropolitan area level food environment factors. Models were fitted using generalised estimating equations to control for metropolitan area level intra-correlation and individual level sociodemographic characteristics. It was found that adults residing in cities with a large share of supermarket and full-service restaurant workers were less likely to be obese, while adults residing in cities with a large share of convenience store and fast food restaurant workers were more likely to be obese. Supermarkets and full-service restaurant workers are concentrated in the Northeast and West of the US, where obesity prevalence is relatively lower, while convenience stores and fast-food restaurant workers are concentrated in the South and Midwest, where obesity prevalence is relatively higher. The food environment landscapes measured at the metropolitan area level explain the continental-scale patterns of obesity prevalence. The types of food that are readily available and widely served may translate into obesity disparities across metropolitan areas.

    With the development of the rural economy in China, rural household's consumption behavior in main grain producing area has being changed, which influence the adjustment of Agricultural industrial structure and agricultural industrial policy. In this article,we use Almost Ideal Demand System(AIDS) to estimate the elasticities of demand expenditure and price(own price elasticity and cross-price elasticity) and then to analyze food consumption behavior of rural household in main grain producing area. The results show that foods such as rice, wheat, pork, beef in main grain producing area have the positive elasticities of demand expenditure. According to the cross-price elasticity, the demand for eggs, mutton, beef and pork is more affected by the fluctuation of other food's price, while the demand for the wheat, rice, maize and soybean is less affected by thefluctuation of other food's price. Based on the results, some policy recommendations, such as increasing farmer's income, expanding the animal food production, stabilize food's price, are put forward correspondingly.in the article.

    Taxes and subsidies are increasingly being considered as potential policy instruments to incentivize consumers to improve their food and beverage consumption patterns and related health outcomes. This study provided a systematic review of recent U.S. studies on the price elasticity of demand for sugar-sweetened beverages (SSBs), fast food, and fruits and vegetables, as well as the direct associations of prices/taxes with body weight outcomes. Based on the recent literature, the price elasticity of demand for SSBs, fast food, fruits and vegetables was estimated to be -1.21, -0.52, -0.49 and -0.48, respectively. The studies that linked soda taxes to weight outcomes showed minimal impacts on weight; however, they were based on existing state-level sales taxes that were relatively low. Higher fast-food prices were associated with lower weight outcomes particularly among adolescents, suggesting that raising prices would potentially impact weight outcomes. Lower fruit and vegetable prices were generally found to be associated with lower body weight outcomes among both low-income children and adults, suggesting that subsidies that would reduce the cost of fruits and vegetables for lower-socioeconomic populations may be effective in reducing obesity. Pricing instruments should continue to be considered and evaluated as potential policy instruments to address public health risks.

    Background Little is known about the influence of in-town fast-food availability on family-level fast-food intake in nonmetropolitan areas. Purpose The purpose of the current study was to determine whether the presence of chain fast-food outlets was associated with fast-food intake among adolescents and parents, and to assess whether this relationship was moderated by family access to motor vehicles. Methods Telephone surveys were conducted with 1547 adolescent–parent dyads in 32 New Hampshire and Vermont communities between 2007 and 2008. Fast-food intake in the past week was measured through self-report. In-town fast-food outlets were located and enumerated using an onsite audit. Family motor vehicle access was categorized based on the number of vehicles per licensed drivers in the household. Poisson regression was used to determine unadjusted and adjusted risk ratios (RRs). Analyses were conducted in 2011. Results About half (52.1%) of adolescents and 34.7% of parents consumed fast food at least once in the past week. Adolescents and parents who lived in towns with five or more fast-food outlets were about 30% more likely to eat fast food compared to those in towns with no fast-food outlets, even after adjusting for individual, family, and town characteristics (RR=1.29, 95% CI= 1.10, 1.51; RR=1.32, 95% CI=1.07,1.62, respectively). Interaction models demonstrated that the influence of in-town fast-food outlets on fast-food intake was strongest among families with low motor vehicle access. Conclusions In nonmetropolitan areas, household transportation should be considered as an important moderator of the relationship between in-town fast-food outlets and family intake. PMID:22608373

    Urbanization processes are intertwined with nutritional transition because there is easier access to food of low nutritional quality at reduced prices, changing dietary patterns and leading to an increase of non-communicable chronic diseases. This study aims to understand the perceptions for high blood pressure, obesity, and alcoholism, describing some interactions of these dimensions in the problem of food security in the city of Praia. A qualitative study was carried out under the framework of the research project “UPHI-STAT: Urban Planning and Health Inequalities—moving from macro to micro statistics”. Ten focus groups were conducted in three urban areas with distinct characteristics in the city of Praia, with a total of 48 participants. Participants reported frequent consumption of foods with poor nutritional quality, understanding the potential danger in terms of food security in the city of Praia. Easy access to and high levels of alcohol consumption, and poor quality of traditional drinks were mentioned by participants in the study areas. The impact of the economic situation on the possibility of access to safe and healthy options emerged as a differentiating factor. PMID:27879689

    Full Text Available The price volatility and scarcity have been became a great problem in the distribution system of seasonal staple food produced by agro industry. It has salient supply disparity during the harvest and planting season. This condition could cause disadvantages to the stakeholders such as producer, wholesaler, consumer, and government. This paper proposes a buffer stock model under free trade considerations to substitute quantitative restrictions and tariffs by indirect market intervention instrument. The instrument was developed through buffer stock scheme in accordance with warehouse receipt system (WRS and collateral management system. The public service institution for staple food buffer stock (BLUPP is proposed as wholesaler’s competitor with main responsibility to ensure price stabilization and availability of staple food. Multi criteria decision making is formulated as single objective a mixed integer non linear programming (MINLP. The result shows that the proposed model can be applied to solve the distribution problem and can give more promising outcome than its counterpart, the direct market intervention instrument.

    The purpose of this report is to present the methodology and results of an analysis of income distribution impacts associated with changes in the Western Area Power Administration (WAPA) marketing program. The focus will be on the distribution of personal income across eleven brackets in each of nine sub-regions of the WAPA market area. Moreover, these results will be translated into an assessment of the number of people who stand to gain or lose as a result of the policies and the size of these income changes. Most economic impact analyses are performed at an aggregate level. The results are typically presented in terms of net benefits, or a listing of changes in employment, output, income, or prices. What is neglected is the distribution of impacts across the affected population. These distributional impacts are important for several reasons. First, there is the normative judgmental issue of distributional justice, or equity. This addresses concerns about income disparities in general, or whether the poor, or any other group, are shouldering a disproportionate share of any burden or are failing to share significantly in any gain.

    Food prices are expected to affect dietary intakes, however, previous findings are mixed and few are based on nationally representative data. We examined the associations of price indices of fast foods (FF-PI) and fruits and vegetables (FV-PI) with dietary intakes and BMI among U.S. children and adolescents using data from the Continuing Survey of Food Intakes by Individuals (CSFII; 1994-1998) for 6759 children (2-9 y) and 1679 adolescents (10-18 y). FF-PI and FV-PI were linked to individuals' CSFII dietary data through city-level geocodes. Main outcomes included intakes of selected nutrients and food groups, a fast food consumption index (FF-CI), diet quality using the 2005 Healthy Eating Index (HEI), and BMI. Among children (2-9 y), a higher FF-PI (by $1) was associated with intakes of lower FF-CI (β ± SE: -0.9 ± 0.3 count/d), higher HEI (6.6 ± 2.5), higher intakes of fiber (2.7 ± 0.7 g/d), calcium (225.7 ± 52.3 mg/d), dairy (172.5 ± 36.2 g/d), and fruits and vegetables (113.3 ± 23.4 cup equivalents/d). FV-PI was inversely related to fiber intake (β ± SE: -3.3 ± 1.5 g/d) and positively associated with BMI (4.3 ± 1.2 kg/m(2)). Less consistent findings were ascribed to FV-PI and among adolescents (10-18 y). Significant associations were almost equally balanced between low and high family income groups, with some significant interactions between food prices and family income observed, particularly among children (2-9 y). Our findings suggest that among U.S. children aged 2-9 y, higher FF-PI is associated with better dietary quality, whereas higher FV-PI is linked to higher BMI and lower fiber intake. Associations varied by family income in children for many dietary intake variables.

Little is known about the biological and psychological (top-down bases that maintain this pathological state. However, Anorexia Nervosa is a biological, psychological and social model where the main behavioral characteristic is the inhibition of eating behavior; not by bottom-up but top-down regulation. Objective: To explore the areas of the brain associated with food appetency through functional magnetic resonance in women with anorexia nervosa. Methods: The subjects include 5 female with Restrictive type of Anorexia Nervosa and five controls female with similar in age and low weigh. The subjects were within the MRI scanner and while took fMRI they saw food images that would generate appetite. The subjects were in fasting state and mentally prepare by instruction “imagine you are eating the food presented in the following images”. Results: Compared differences in the activation between subjects four regions were found significant: the anterior cingulate, left front medial region and the left and right midbrain. Conclusions: The patients with Anorexia Nervosa present different activated cerebral areas to those of the controls during the visual exposition to food in hungry state and with evoke cognitions associated with eat food; those regions may be implicated in reward and self-control.

    Full Text Available This research focuses on social interaction associated with price transmission in a multi-tier rice supply chain. A case study and qualitative methods are employed to examine a well-established supply network in Karawang District in Indonesia. Farmers and traders used their existing network in selling rice crops to traders and adopted a payment scheme for cash-and-carry transactions. Information on the market situation was obtained through personal interviews and observations including text messaging with farmer and trader informants. Evidence reveals that social relationships are vital in transmitting price information among networked actors to maintain the flow of rice, mitigate risk, and avoid losses due to poor quality of the rice product. Findings show that social interaction enables actors in an end-to-end rice supply chain to deal with the assurance of supply rationing.

    Data obtained during a hydrologic study of the Price River basin, Utah, are used to describe seasonal variations of flow of springs, relation between ground water and surface water, hydraulic properties of the ground-water reservoir, ground-water recharge and discharge, flood characteristics of streams, mineralogic composition and depositional rates of sediments, nutrient and inorganic loading in streams and Scofield Reservoir, and water budgets for selected basins. Additional study and monitoring are needed to detect possible hydrologic changes caused by coal mining. Much of the ground-water discharge from the Star Point Sandstone in the Mesaverde Group in the Wasatch Plateau occurs along faults. In the Book Cliffs, where faulting is less extensive, most of the ground-water discharge is from the Flagstaff Limestone. The Flagstaff Limestone is greatly diffusive, has a small storage coefficient, and contains water which is perched. Springs issuing from the Star Point Sandstone in the Mud Creek drainage (Wasatch Plateau) had recession indexes greater than 365 days per log cycle. Springs issuing at higher altitudes from the Colton Formation and the Flagstaff Limestone in the Soldier Creek area (Book Cliffs) have great seasonal variability, with recession indexes ranging from 24 to 115 days per log cycle. Estimated transmissivities in the Soldier Creek area ranged from 0.003 foot squared per day in the lower part of the Castlegate Sandstone to 0.07 foot squared per day in the Price River Formation. Seepage from the Star Point Sandstone is the major contributor to base flow of the stream in Eccles Canyon (Wasatch Plateau). Gains of as much as 230 gallons per minute occurred near a fault zone which crosses Eccles Canyon at the junction with South Fork Canyon. The potentiometric surface of water in the Blackhawk Formation in the Wasatch Plateau (Mud Creek drainage) and the Book Cliffs (Soldier Creek area) generally is above the coal zones, and dewatering will be necessary

We try to determine whether asset prices are useful indicators for determining future inflation rates and we analyze the tensions in the interbank market during the last five years by means of a GARCH (1,1 model. The results show that the interest rate leads to a decrease in the inflation rate, while oil and real estate prices give a positive impulse. Before the crisis, Euribor-Eoniaswap spread had a low volatility. But the intervention of central banks by injecting liquidity into the banking system led to a considerable increase in its volatility. Another explanation for the evolution of this phenomenon is due to the loss of control by the ECB on the MBR and Eoniaswap spread.

    In 2014 an excise tax to non-alcoholic sweetened beverages (SSB) was implemented in Mexico. The objective of this paper is to study whether and to what degree these taxes passed-through onto SSB prices in urban areas overall and by region, type of beverage and package size. Prices were obtained from the National Institute of Statistics and Geography from 2011 to 2014. We applied a pre-post quasi-experimental approach using fixed effects models. In sensitivity analysis we applied other model specifications to test the robustness of the findings and we also present weighted estimations based on household purchases. The dependent variables are real prices of a specific beverage category; the main independent variables are dummies for each month of 2014, and the models adjust for time trends and seasonality. Results suggest that the SSB tax passed along to consumers for all SSBs and we found overshifting for the carbonated SSBs. A greater effect is seen among the small package sizes, and we see heterogeneous effects by region. Estimating the effect of the tax on prices is important to understand the potential effect on consumption.

    More than two centuries ago in his Essay on the Principle of Population, Thomas Malthus famously issued his dire prediction that mankind was doomed to survival at a subsistence level. His concept of population growth expanding to absorb the available food supply has been roundly contradicted by history, thanks in part to a declining birth rate in rich countries. However, economics is still the “dismal science”, as the underlying idea of natural resource scarcity impinging on the prospects for...

    Aiming to investigate the effect of diet and food consumption with regard to health, environment, and economy in light of nutrition ecology, we studied the dimensions of nutrition and food security in urban and rural settings in the region of Chapada dos Veadeiros, Central Brazil. We tracked diet and food consumption through carbon and nitrogen stable isotope ratios in fingernails of these inhabitants together with food intake data as a proxy for their diet patterns. We estimated household food insecurity by using the Brazilian Food Insecurity Scale. Nutrition and food insecurity was observed in both urban and rural areas, but was accentuated in rural settings. The diet pattern had high δ(13)C values in fingernails and low δ(15)N. Both urban and rural areas have diets with low diversity and relying on low-quality processed food staples at the same time that nutrition and food insecurity is quite high in the region.

Traffic congestion is a global epidemic that at time has put cities to a state of paralysis. From a microeconomics point of view, congestion can be approached as a negative externality that merits a Pigovian tax to correct the suboptimal equilibrium. Externalities manifest in delays and wasteful urbanization. While the efficiency of congestion pricing has been well established since the late 1970s, policy adoption and implementation have been delayed due to technological

    Given the limited resources of fossil energy, and the environmental risks of excess fertilizer on crops, it is time to reappraise the potential role of food legume biological nitrogen fixation (BNF) as sources of nitrogen for cropping systems in China. 150 soil samples across 17 provinces and 2 municipalities of China were collected and analyzed. A distribution map of the soil fertilities and their patterns of distribution was constructed. The pH results indicated that soils were neutral to slightly alkaline overall. The soil organic matter (SOM) and the available nitrogen (AN) content were relatively low, while the available phosphorus (AP) and available potassium (AK) contents were from moderate to high. Production areas of food legumes (faba bean, pea, adzuki bean, mung bean and common bean) were clearly separated into 4 soil fertility type clusters. In addition, regions with SOM, AN, AP and AK deficiency, high acidity and high alkalinity were listed as target areas for further soil improvement. The potential was considered for biological nitrogen fixation to substitute for the application of mineral nitrogen fertiliser.

    Vehicle miles traveled (VMT) is the primary determinant of traffic congestion, vehicle crashes, greenhouse gas emissions, and other effects of transportation. Two previous studies have sought to explain VMT levels in urbanized areas. This study updates and expands on previous work with more recent data, additional metrics, and structural equation modeling (SEM) to explain VMT levels in 315 urbanized areas. According to SEM, population, income, and gasoline prices are primary exogenous drivers of VMT. Development density is a primary endogenous driver. Urbanized areas with more freeway capacity are significantly less dense and have significantly higher VMT per capita. Areas with more transit service coverage and service frequency have higher development densities and per capita transit use, which leads to lower VMT per capita. The indirect effect of transit on VMT through land use, the so-called land use multiplier, is more than three times greater than the direct effect through transit ridership.

    Integrated food security covers three aspects: food quantity security, food quality security, and sustainable food security. Because sustainable food security requires that food security must be compatible with sustainable development, the risk assessment of sustainable food security is becoming one of the most important issues. This paper mainly focuses on the characteristics of sustainable food security problems in the major grain-producing areas in China. We establish an index system based on land resources and eco-environmental conditions and apply a dynamic assessment method based on status assessments and trend analysis models to overcome the shortcomings of the static evaluation method. Using fuzzy mathematics, the risks are categorized into four grades: negligible risk, low risk, medium risk, and high risk. A case study was conducted in one of China's major grain-producing areas: Dongting Lake area. The results predict that the status of the sustainable food security in the Dongting Lake area is unsatisfactory for the foreseeable future. The number of districts at the medium-risk range will increase from six to ten by 2015 due to increasing population pressure, a decrease in the cultivated area, and a decrease in the effective irrigation area. Therefore, appropriate policies and measures should be put forward to improve it. The results could also provide direct support for an early warning system-which could be used to monitor food security trends or nutritional status so to inform policy makers of impending food shortages-to prevent sustainable food security risk based on some classical systematic methods. This is the first research of sustainable food security in terms of risk assessment, from the perspective of resources and the environment, at the regional scale.

    As an important measure of ecoenvironmental construction, the process of de-farming in slope farmland is being undertaken gradually in the whole China. Meanwhile, the problem of reducing in food yield in de-farming areas can not be neglected any more. It is especially the case in areas with concentrated slope farmland and inconvenient transportation. In this paper, we analyze the causes of hidden troubles in food security, and the spatial relationship between farmland and slope farmland in the reservoir area of Three Gorges, and unveil the spatial disparity of contradictions between food supply and demand. Finally, combining the accessibility of areas, three different spatial types of food security, food security area, food alert area, and food crisis area, are divided.

    The estimation of price elasticities of alcohol demand is valuable for the appraisal of price-based policy interventions such as minimum unit pricing and taxation. This study applies a pseudo-panel approach to the cross-sectional Living Cost and Food Survey 2001/2-2009 to estimate the own- and cross-price elasticities of off- and on-trade beer, cider, wine, spirits and ready-to-drinks in the UK. A pseudo-panel with 72 subgroups defined by birth year, gender and socioeconomic status is constructed. Estimated own-price elasticities from the base case fixed effect models are all negative and mostly statically significant (pEstimated cross-price elasticities are smaller in magnitude with a mix of positive and negative signs. The results appear plausible and robust and could be used for appraising the estimated impact of price-based interventions in the UK.

    The lack of market variables in fishery systems (i.e., prices and quantities) has often been cited as one reason for the particular difficulty of understanding whole marine ecosystem change and its management under a broader ecosystem perspective. This paper shows the results of efforts to tackle this problem in the South Brazil Bight by compiling and analyzing in-depth an unprecedented 40-year database from the region’s largest wholesale seafood market, based in the megacity of São Paulo. Fishery landings and market values for the period 1968-2007 were analyzed primarily by updated trophic level classes and multispecies indicators including the (1) marine trophic index (MTI), (2) weighted price, and (3) log relative price index (LRPI) which relates prices and trophic levels. Moreover, an inferential analysis of major seafood category statistical trends in market prices and quantities and their positive and negative correlations was undertaken. In general, these market trends contributed substantially to identifying and clarifying the changes that occurred. Considerations of the behavior of demand, supply and markets are included. In particular, while the MTI did not support a “fishing down the marine food web” hypothesis, other indicators did show the continued scarcity of major high trophic level categories and fisheries target species. Overall, the results indicate that the analysis of fishery landings, or of certain other indicators alone, can mask real changes. Rather, a joint ecological-econometric analysis provides better evidence of the direction of ecosystem pressures and stock health. This method for detecting market changes across the food web may be particularly helpful for systems considered data-poor but where fish market data have been archived. This study further elucidates historical changes and fishing impacts in the South Brazil Bight ecosystem.

    Full Text Available Food security has been one of the major developmental objectives in India. Though India has sufficient food production yet the achievement did not percolate down to households.This paper reports on an investigation into the food security status in Vaishali district of Bihar. Data were gathered across 16 administrative divisions in the district and eventually959 farmers’ households were sampled using stratified random sampling techniques. This allowed computing composite food security index to assess the relative status of foodsecurity of the sampled farmers. The findings revealed that 75 % of the sampled households have low food security. Within farmers’ categories, most of the large farmers had high food security. Medium farmers experienced moderate food security while semimedium, small and marginal farmers were having low food security. Bivariate regression analyses between food security and its components of all the farmers shows foodavailability has a major impact on food security as 93 % variation in food security is explained by variation in food availability. The study suggested that priority should be accorded for creating rural employment opportunities, providing infrastructure forincreasing production and creating awareness of education for long term sustainability of food security in the study area.Key words : Food security components, Food security, India

    Full Text Available Achieving food security is still a major problem for households in most rural areas of Nigeria. This study was therefore designed to assess the food security status among farming households in rural areas of Kano state, Nigeria. The study utilized a multistage random sampling technique to +select a sample of 120 rural farm households for interview. Data collected were analysed using percentages, mean score, logistic regression and food security index. Using the food security index approach, the study revealed that 74% of the respondents were food secure while 26% were food insecure. The results of the logistic regression revealed that educational level (p0.05; z = 1.95, sex (p0.05; z = 1.99, household size (p0.05; -4.29 and access to credit (p0.05; z = 2.4 were significant determinants of food security. Also, the major effect of food insecurity on the households include reduction in household income/ savings due to increased expenditure on food (M= 3.58, among others. The perceived coping strategies in cushioning the effects of food insecurity include engaging in off-farm and non-farm jobs to increase household income, (M= 2.77, among others. The study therefore recommends the fast tracking of already established policy measures aimed at reducing food insecurity in the country. Also, efforts aimed at reducing food insecurity among rural farming households should focus on increasing household income and food supply.

    2016-06-01

    Several studies have shown that low-cost foods have an equivalent nutrient composition compared to high-cost foods, but such information is lacking in Switzerland. Thus, we compared the caloric and nutrient content of "best price" (BPF) and brand name foods (BNF) in Switzerland using the version 5.0 (April 2015) of the Swiss Food and Nutrient composition database. Over 4000 processed food items were included and 26 food categories were compared regarding total energy, protein, fat and carbohydrates, saturated fatty acids, sugar, fiber and sodium. BPF, namely core food categories like Bread, Red meat, White meat and Fish products, were 42%, 39%, 42% and 46% less expensive than their BNF equivalents, respectively. No differences were found between BPF and BNF regarding total energy and protein, fat and carbohydrates for most food categories. In the Cheese category, BPF had a lower caloric content than BNF [Median (interquartile range, IQR): 307 (249-355) vs. 365 (308-395) kcal/100 g, respectively, p < 0.001]; BPF also had lower fat and saturated fatty acid content but higher carbohydrate content than BNF (both p < 0.01). In the Creams and puddings group, BPF had lower fat 1.3 (0.9-1.7) vs. 6.0 (3.5-11.0) g/100 g and saturated fatty acid 0.6 (0.6-0.8) vs. 2.9 (2.3-6.0) g/100 g content than BNF (both p < 0.005). In the Tinned fruits and vegetables group, BPF had lower sodium content than BNF: 175 (0-330) vs. 370 (150-600) mg/100 g, p = 0.006. BPF might be a reasonable and eventually healthier alternative of BNF for economically deprived people in Switzerland.

Combining these three components of price dynamics shows that the variation in real prices post-2000 was substantially greater than that in the 1980s and 1990s, and was approximately equal to the extreme volatility in commodity prices that was experienced in the 1970s. Macro policy, exchange rates, and petroleum prices were important determinants of price variability over 2005–2010, highlighting the new linkages between the agriculture-energy and agriculture-finance markets that affect the world food economy today. These linkages contributed in large part to misguided expectations and uncertainty that drove prices to their peak in 2008. The article also argues that there is a long-lasting effect of price spikes on food policy around the world, often resulting in self-sufficiency policies that create even more volatility in international markets. The efforts by governments to stabilize prices frequently contribute to even greater food insecurity among poor households, most of which are in rural areas and survive on the margin of net consumption and net production. Events of 2008—and more recently in 2010—underscore the impact of price variability for food security and the need for refocused policy approaches to prevent and mitigate price spikes.

    This study investigated the food risk perceptions of people living in the Triveneto area (Northeast Italy), a territory characterized by a particular interest in the production of quality foodstuffs, to determine what aspects people associate with food risk and to understand what beliefs underlie these perceptions. Four focus groups were conducted in the major towns of the target area (N = 45). A semi-structured interview was used that focused on beliefs about food risks, the use of information and media sources in relation to food risk, and the behaviours adopted when eating outside the home. A homogeneous view of food risk emerged among the respondents, and a common definition of risky food was identified. The concept of risk was in opposition to the quality and controllability of food, which emerged as major strategies to cope with food risks. Quality was linked to freshness and local origin, whereas controllability reflected a direct (e.g., checking labels, having a relationship with the vendor, cultivating one's own vegetable garden) or indirect (e.g., control guarantees provided by suppliers and the government) means to check the safety and quality of food. Although people seemed quite informed about food risks, a common sense of impotence with regard to one's own protection prevailed, together with a fatalistic sense of incomplete control over risk. The results identified food concerns for consumers living in this specific territory and might represent a starting point for public health authorities to increase compliance with responsible behaviours for risk mitigation and to define successful food policies for this area.

    Full Text Available This paper is one of the few marketing research done in rural areas of attitudes towards green products. Even if the subject is generally treated at the international level, Romania has an important specific is to be taken into account in the European area. Size of agricultural holdings and their degree of technology do not have the desired agricultural economic efficiency of modern economies. But by applying marketing techniques and by approaching customer needs, the agricultural sector in Romania can develop in another direction no longer going through the business model of major West European farmers. We are referring here to transition to a agriculture on small areas, intensively exploited and ecology and a system of distributed in the markets with a big search for such products. But he must know how people in rural areas see these green products and how they are trained to understand the concepts of green marketing and marketing organic products. These issues have been dealt with in the first part of the work. The second part of this paper aims to describe the attitude of small agricultural producers towards organic products and the degree in which they are willing to go to such a production. Research is based on a survey an explorer in two rural areas of Romania one at the mountain and the other in lowlands and shows the degree of adaptation for small producers to new market requirements. Results have been contradictory. Some of them have confirmed the assumptions, namely the opening to such a grown for, and others have shown a much greater degree of the use of chemical compounds in agriculture than expected. Also the degree of taking the initiative in rural areas was an issue that came out at a level lower than expected. This is a worrying conclusion but worth being taken into account. This research gives the image concept in rural areas being the starting point for further research and strategies which to propose turning Romania into a

    Several spatial measures of community food access identifying so called "food deserts" have been developed based on geospatial information and commercially-available, secondary data listings of food retail outlets. It is not known how data inaccuracies influence the designation of Census tracts as areas of low access. This study replicated the U.S. Department of Agriculture Economic Research Service (USDA ERS) food desert measure and the Centers for Disease Control and Prevention (CDC) non-healthier food retail tract measure in two secondary data sources (InfoUSA and Dun & Bradstreet) and reference data from an eight-county field census covering169 Census tracts in South Carolina. For the USDA ERS food deserts measure accuracy statistics for secondary data sources were 94% concordance, 50-65% sensitivity, and 60-64% positive predictive value (PPV). Based on the CDC non-healthier food retail tracts both secondary data demonstrated 88-91% concordance, 80-86% sensitivity and 78-82% PPV. While inaccuracies in secondary data sources used to identify low food access areas may be acceptable for large-scale surveillance, verification with field work is advisable for local community efforts aimed at identifying and improving food access.

  19. Markets, Climate Change and Food Security in West Africa

    Science.gov (United States)

    Brown, Molly E.; Hintermann, Beat; Higgins, Nathaniel

    2009-01-01

    West Africa is one of the most food insecure regions of the world. Sharply increased food and energy prices in 2008 brought the role of markets in food access and availability around the world into the spotlight, particularly in urban areas. The period of high prices had the immediate consequence of sharply increasing the number of hungry people in the region without boosting farmer incomes significantly. In this article, the interaction between markets, food prices, agricultural technology and development is explored in the context of West Africa. To improve food security in West Africa, sustained commitment to investment in the agriculture sector will be needed to provide some protection against global swings in both production and world markets. Climate change mitigation programs are likely to force global energy and commodity price increases in the coming decades, putting pressure on regions like West Africa to produce more food locally to ensure stability in food security for the most vulnerable.

    Full Text Available This study was aimed to determine the profitability of smallholder dairy farmers at the lowland areas of Yogyakarta related to dairy cow performance (milk production to be achieved at various fresh milk market prices. Thirty lactating Holstein cows belonging to the 16 farmers at the lowland areas of Yogyakarta Province selling milk directly to the consumers were drawn as the samples. Profitability was determined by enterprise budgeting (accounting profit and economic profit and break even point. Input and output data were obtained from interview with the farmer samples along with direct observations on the cows performance. The results indicated that under the observed condition of 9.28 liter/day average milk production at IDR 4,700 market price, the accounting profit was found to be IDR 7,758,862/lactating cow/year. The farmers were able to make an economic profit of IDR 1,839,875 with profit margin index of 0.12. If the farmers have to sell the fresh milk to the Cooperatives at the price of IDR 2.800 or IDR 3.200/liter, in order to gain a positive economic profit, milk production must be at least 13.5 or 12.0 liters/day, respectively.

    This paper focuses on a survey of uranium and thorium decay chain radionuclides in food and drinking water from the thorium-rich (monazite-bearing) region of Buena, which is located in the state of Rio de Janeiro, Brazil. The radionuclide concentration values in the food and drinking water from Buena reached values higher than 100-fold the international reference values. The daily intake of radionuclides by the local population is similar to that of another high background radiation area in Brazil, but the intake is higher than that of residents from a normal background radiation area. Approximately 58 % of the food consumed by Buena inhabitants is produced locally. Based on that figure, locally produced food and the dilution of total radionuclides in the diet of residents caused by food importation are both highly relevant to a population's intake of radionuclides. The concentration values for (210)Pb and the radium isotopes in drinking water from Buena are among the highest values to be reported in the literature. (228)Ra is the most important radionuclide ingested with both food and water among the inhabitants of Buena.

    To maintain nutrient homeostasis the central nervous system integrates signals that promote or inhibit eating. The supply of vital amino acids is tuned by adjusting food intake according to its dietary protein content. We hypothesized that this effect is based on the sensing of individual amino acids as a signal to control food intake. Here, we show that food intake was most potently reduced by oral L-arginine (Arg), L-lysine (Lys) and L-glutamic acid (Glu) compared to all other 17 proteogenic amino acids in rats. These three amino acids induced neuronal activity in the area postrema and the nucleus of the solitary tract. Surgical lesion of the area postrema abolished the anorectic response to Arg and Glu, whereas vagal afferent lesion prevented the response to Lys. These three amino acids also provoked gastric distension by differentially altering gastric secretion and/or emptying. Importantly, these peripheral mechanical vagal stimuli were dissociated from the amino acids' effect on food intake. Thus, Arg, Lys and Glu had a selective impact on food processing and intake suggesting them as direct sensory input to assess dietary protein content and quality in vivo. Overall, this study reveals novel amino acid-specific mechanisms for the control of food intake and of gastrointestinal function.

    This report presents a multi-area economic load dispatching control scheme with a combination of spot pricing as a demand-side option and economic power interchange as a supply-side option to keep demand and supply balance. In this study, the dynamic economic load dispatching control (ELD) technique is used with some modifications such as the introduction of a multi-area power interchange and regional spot pricing. To keep demand and supply balance, the region (buyer) that has larger load demand than its maximum generation capacity must control its demand by spot pricing and purchase of interchange power from other regions (sellers) that have excess capacities. We assume that the purchase cost of interchange power is covered by the additional revenue of spot pricing in the buyer. Distribution of interchange power among sellers is determined by the modified economic dispatching rule. Feasibility of the proposed method is shown numerically through simulation studies using a three-area power system model. The following findings are identified: (1) a buyer that has not enough capacity in the peak period can be suppressed its load demand by increasing spot price and then purchases power from some sellers that have excess capacities. This buyer can achieve power balance with this proposed supply and demand measures; (2) the average price of interchange power is lower than regional spot pricing rate under the modified economic dispatching rule for distribution of interchange power among sellers; (3) the regional spot price rate is reduced by the introduction of multi-area power interchange; (4) levels of regional spot price and purchased power price depend heavily on the seller`s generating cost and the level of load demand. 11 refs., 14 figs., 3 tabs.

    Full Text Available Objective: This study aimed to determine the prevalence of food insecurity among schoolchildren living in urban and rural areas of Picos, Piauí associated with the socioeconomic profile of families and their food intake and nutritional status. Methods: Study participants were families with children aged 7-10 years enrolled in municipal schools, totaling 342 families/schoolchildren. The study was conducted at school facilities through interviews with mothers - or guardians - using a questionnaire based on the Brazilian Food Insecurity Scale and socioeconomic variables and food frequency questionnaire. The nutritional status of children was assessed using the following indexes: weight/age, height/age and body mass index/age. Results: The prevalence of food insecurity was high and similar for rural and urban areas, 84.3% and 83.3%, respectively. In general, lower income and consumption of untreated water was associated with greater frequency of food insecurity (p≤0.01. In urban areas, higher percentage of food insecurity was associated to lower educational levels (p≤0.05. Dietary intake and nutritional status of schoolchildren were not associated with food insecurity condition of families. Conclusion: The percentage of families at food insecurity, as well as the food consumption and nutritional status of schoolchildren were similar between urban and rural areas, characterized as a homogeneous population in terms of socioeconomic conditions.

    Full Text Available Mountains of Central Alborz Protected Area hold a big population of brown bear, the largest varnivore species in Iran. Understanding food habits is crucial to understanding the ecology of the species. Diet influences many ecological and life-history traits, such as spatial distribution, social and foraging behavior, body mass and reproduction. Therefore, during Jun 2006 to May 2007 we had a comprehensive study on brown bear food habits, as the largest omnivorous of the country in Central Alborz Protected Area. Our investigation showed that plant materials composed the main proportion of food items of the brown bears in the spring until mid-summer. Insects, especially ants were predominantly eaten in the first half of summer. As approaching to hibernation period in late autumn, fruits played the main role of bear food items having high fat content. We never witnessed bear attack on wild herbivores. Furthermore, we never found remains of wild herbivores except a few livestock remains in brown bear scats during our survey period. Accordingly, we concluded that brown bears were almost herbivorous in the Central Alborz Protected Area. We never found any bear scats or fresh signs in three consecutive years, between first of December until mid of March. Also, no direct sighting of brown bear was reported to us by local people and game keepers within the mentioned period. Accordingly, it can be concluded that the brown bears hibernate for a period of 3-3.5 months in winter in the Central Alborz Protected Area.

    With the increase of global population, grain-popula- tion relationship has attracted great attention worldwide. In China, grain-population relationship has become an increasingly impor- tant economic concern. Of central importance to the food security debate in China is the geography of grain supply and demand. This paper uses a grain demand and supply index (DSR) to analyze the spatial-temporal relationship between population and grain in China from 1949 to 2007 at national and provincial scales. The results are examined in three periods. (1) From 1949 to 2007, with the increase of grain production, the relationship between popula- tion and grain of China improved considerably. (2) Over the past 35 years (1970-2005), on the whole the grain producing areas have had grain surplus and contributed to the nation by providing grain, but the ability to provide sufficient grain is not stable. (3) Over the past 15 years (1990-2005), decreases in planting area brought pres- sure on national grain food security. The paper concludes that the key to providing more food for the main food producing provinces is increasing yield on the basis of steady plant area.

    Because of the major international-level events that have recently been held in Brazil, concerns about the sensory and hygienic-sanitary conditions of food have increased. The objective of this study was to evaluate the implementation of good handling practices in food and beverage areas of hotels, with and without outsourced professional intervention. We evaluated 19 food and beverage areas in hotels in Porto Alegre, Rio do Sul, Brazil, using a checklist that was developed by a municipal surveillance team based on existing laws for good handling practices. The evaluation was done by a skilled professional in the food safety area on two occasions, at the beginning of the study (January to May 2013) and at the end (July to November 2014), and the establishments were classified as good, regular, or poor. After the baseline evaluation, an action plan listing the noncompliance found at each location was given to those responsible for the establishments, and a period of 1 year 6 months was stipulated for improvements to be made. In the repeat evaluation, those responsible for the establishments were asked whether they had hired an outsourced professional to assist them in the improvements. The hotels showed improvement during the repeat evaluation, but a significant increase in the percentage of overall adequacy was seen only in the food and beverages areas of the 12 hotels that used the intervention of an outsourced professional. The better percentage of adequacy in establishments with outsourced professional intervention underlines the importance of an external and impartial view of routine activities in the implementation of good handling practices.

    2015-04-01

    With retail scanner data, we applied hedonic price modeling to explore price premiums for organic, local, and other product attributes of fluid milk in Hawaii. Within the context of revealed preference, this analysis of organic and local attributes, under a single unified framework, is significant, as research in this area is deficient in the existing literature. This paper finds both organic and local attributes delivered price premiums over imported, conventional, whole fluid milk. However, the estimated price premium for organic milk (24.6%) is significantly lower than findings in the existing literature. Likewise, the price premium for the local attribute is estimated at 17.4%, again substantially lower compared with an earlier, stated preference study in Hawaii. Beyond that, we estimated a robust price premium of 19.7% for nutritional benefits claimed. The magnitude of this estimated coefficient reinforces the notion that nutrition information on food is deemed beneficial and valuable. Finally, package size measures the influence of product weight. With each larger package size, the estimate led to a corresponding larger price discount. This result is consistent with the practice of weight discounting that retailers usually offer with fresh packaged food. Additionally, we estimated a fairly high Armington elasticity of substitution, which suggests a relatively high degree of substitution between local and imported fluid milk when their relative price changes. Overall, this study establishes price premiums for organic, local, and nutrition benefits claimed for fluid milk in Hawaii.

    Full Text Available Abstract Background Individuals and families are relying more on food prepared outside the home as a source for at-home and away-from-home consumption. Restricting the estimation of fast-food access to fast-food restaurants alone may underestimate potential spatial access to fast food. Methods The study used data from the 2006 Brazos Valley Food Environment Project (BVFEP and the 2000 U.S. Census Summary File 3 for six rural counties in the Texas Brazos Valley region. BVFEP ground-truthed data included identification and geocoding of all fast-food restaurants, convenience stores, supermarkets, and grocery stores in study area and on-site assessment of the availability and variety of fast-food lunch/dinner entrées and side dishes. Network distance was calculated from the population-weighted centroid of each census block group to all retail locations that marketed fast food (n = 205 fast-food opportunities. Results Spatial access to fast-food opportunities (FFO was significantly better than to traditional fast-food restaurants (FFR. The median distance to the nearest FFO was 2.7 miles, compared with 4.5 miles to the nearest FFR. Residents of high deprivation neighborhoods had better spatial access to a variety of healthier fast-food entrée and side dish options than residents of low deprivation neighborhoods. Conclusions Our analyses revealed that identifying fast-food restaurants as the sole source of fast-food entrées and side dishes underestimated neighborhood exposure to fast food, in terms of both neighborhood proximity and coverage. Potential interventions must consider all retail opportunities for fast food, and not just traditional FFR.

    Lee, Bruce Y; McGlone, Sarah M

    2010-08-01

    New vaccine pricing is a complicated process that could have substantial long-standing scientific, medical, and public health ramifications. Pricing can have a considerable impact on new vaccine adoption and, thereby, either culminate or thwart years of research and development and public health efforts. Typically, pricing strategy consists of the following ten components: 1. Conduct a target population analysis; 2. Map potential competitors and alternatives; 3. Construct a vaccine target product profile (TPP) and compare it to projected or actual TPPs of competing vaccines; 4. Quantify the incremental value of the new vaccine's characteristics; 5. Determine vaccine positioning in the marketplace; 6. Estimate the vaccine price-demand curve; 7. Calculate vaccine costs (including those of manufacturing, distribution, and research and development); 8. Account for various legal, regulatory, third party payer, and competitor factors; 9. Consider the overall product portfolio; 10. Set pricing objectives; 11. Select pricing and pricing structure. While the biomedical literature contains some studies that have addressed these components, there is still considerable room for more extensive evaluation of this important area.

What motivates the analysis is the recent surge in international commodity prices and the controversy over the poverty...... domestic goods. Households prefer the traded good which they substitute towards as their incomes increase, thus exposing themselves to world market price swings. Price transmission from international to domestic markets therefore increases with per capita income but also with income inequality. Model...... using a Bayesian simulation methodology.

The session included business persons involved in growing and selling food, members of the health system, community group members and city government. The purpose was to identify the full range of sectors of society involved in the food system, to identify the perceptions of the food system among the city population, test eight sustainability competency areas developed by MSU faculty as concepts and as they related to urban food systems, and to discover what kinds of decision support tools were needed to foster sustainable food systems in Detroit. The focus group session was video and audio recorded, the tapes transcribed and coded to identify common themes and responses to the competency area concepts. The competency areas presented were: ecological integrity, community well-being/social justice, economic vitality, aesthetic quality, civic responsibility, systems interdependence, critical thinking, and personal growth. Participants indicated that they considered sustainability a value that people in urban agriculture shared, but that people struggled with how to move forward toward sustainability. Focus group participants were able to identify some aspect of each of the eight competency areas that they perceived people in urban agriculture, and the broader city resident population already recognized, or engaged in without recognizing that they were doing something that could lead to more sustainable outcomes. However, participants perceived that a sustainable metropolitan food system remains a somewhat elusive goal to achieve for people engaged in pursuing urban agriculture in Detroit due to a negative perception they expressed that many of the city’s population holds for growing food in the city, and in general for goods produced in the city. Information gained from the focus group and subsequent focus groups

    Using both store-level and aggregated price data from the food away from home component of the Consumer Price Index survey, we show that restaurant prices rise in response to an increase in the minimum wage. These results hold up when using several different sources of variation in the data. We interpret these findings within a model of employment determination. The model implies that minimum wage hikes cause employment to fall and prices to rise if labor markets are competitive but potential...

    Full Text Available AIMS: Inadequate fruit and vegetable (F&V consumption is an important dietary risk factor for disease internationally. High F&V prices can be a barrier to dietary intake and so to improve understanding of this topic we surveyed prices and potential competition between F&V outlet types. METHODS: Over a three week early autumn period in 2013, prices were collected bi-weekly for 18 commonly purchased F&Vs from farmers' markets (FM selling local produce (n = 3, other F&V markets (OFVM (n = 5, supermarkets that neighbored markets (n = 8, and more distant supermarkets (n = 8, (in urban Wellington and Christchurch areas of New Zealand. Prices from an online supermarket were also collected. RESULTS: A total of 3120 prices were collected. Most F&Vs (13/18 were significantly cheaper at OFVMs than supermarkets. Over half of the F&Vs (10/18 were significantly cheaper at nearby compared to distant supermarkets, providing evidence of a moderate 'halo effect' in price reductions in supermarkets that neighbored markets. Weekend (vs midweek prices were also significantly cheaper at nearby (vs distant supermarkets, supporting evidence for a 'halo effect'. Ideal weekly 'food basket' prices for a two adult, two child family were: OFVMs (NZ$76, online supermarket ($113, nearby supermarkets ($124, distant supermarkets ($127, and FMs ($138. This represents a savings of $49 per week (US$26 by using OFVMs relative to (non-online supermarkets. Similarly, a shift from non-online supermarkets to the online supermarket would generate a $13 saving. CONCLUSIONS: In these locations general markets appear to be providing some substantially lower prices for fruit and vegetables than supermarkets. They also appear to be depressing prices in neighboring supermarkets. These results, when supplemented by other needed research, may help inform the case for interventions to improve access to fruit and vegetables, particularly for low-income populations.

    Full Text Available Abstract Background There is a popular belief that out-of-home eating outlets, which typically serve energy dense food, may be more commonly found in more deprived areas and that this may contribute to higher rates of obesity and related diseases in such areas. Methods We obtained a list of all 1301 out-of-home eating outlets in Glasgow, UK, in 2003 and mapped these at unit postcode level. We categorised them into quintiles of area deprivation using the 2004 Scottish Index of Multiple Deprivation and computed mean density of types of outlet (restaurants, fast food restaurants, cafes and takeaways, and all types combined, per 1000 population. We also estimated odds ratios for the presence of any outlets in small areas within the quintiles. Results The density of outlets, and the likelihood of having any outlets, was highest in the second most affluent quintile (Q2 and lowest in the second most deprived quintile (Q4. Mean outlets per 1,000 were 4.02 in Q2, 1.20 in Q4 and 2.03 in Q5. With Q2 as the reference, Odds Ratios for having any outlets were 0.52 (CI 0.32–0.84 in Q1, 0.50 (CI 0.31 – 0.80 in Q4 and 0.61 (CI 0.38 – 0.98 in Q5. Outlets were located in the City Centre, West End, and along arterial roads. Conclusion In Glasgow those living in poorer areas are not more likely to be exposed to out-of-home eating outlets in their neighbourhoods. Health improvement policies need to be based on empirical evidence about the location of fast food outlets in specific national and local contexts, rather than on popular 'factoids'.

    Full Text Available Since the early 1960, farms are one of the alternatively forms of hospitality in few Italian regions located predominately in the north and in the centre of peninsula. In 1985, Italian government promulgated a law in order to regulate this non-conventional form of tourism, by delegating to the regions the direct management of administrative procedures and inspections in farms. Nowadays, Italian agritourist farms represent a good chance to give value in favour of farm by the diversification of agrarian activities and also by holistically promoting local food in a direct connection to local gastronomy, rural heritage and tradition, with positive effects on the endogenous development in rural areas. The aim of the paper was to assess the role of agritourism in raising the socio-economic development of rural space by the diffusion of certified quality food using a quantitative approach and to assess if agritourist and certified quality food were tools able to implement the living conditions in the countryside. The findings have disclosed that tourists from abroad have increased the level of farmer income giving value towards high quality food and farm holidays farms. Instead, the impact of Italian agritourists has been relatively poor because of the economic crisis.

    The assessment of food provisioning services of ecosystems in Three-gorge areas is helpful for better understanding the function of ecosystems in local human well-beings. In this paper, process-based models are used to assess the potential food provisioning services derived from agriculture ecosystems and grassland ecosystems, a modifying model along with normal woodlands and a set of modifying coefficients is built to assess the potential food from woodland ecosystems. A set of power regression models based on environment factors are built to estimate the potential fish production from water ecosystems. Land cover data stemmed from Landsat TM images, as well as other natural and social-economic data in 1km resolution such as temperature, precipitation, and DEM, are used to support these assessment models. It shows that the four ecosystems in Three-gorge areas can provide 85.98×10 12 calories heat, 2.49 billion kilograms protein and 823.4 million kilograms fat. Human carrying capacity model under the balance nutrition pattern is built in this paper, which results in two key findings: ecosystems in Three-gorge areas can feed 45.92 million people under wealthy living standard which is 1.53 times of the current population, and the sustainable population is from 9.69 to 36.23 million under that living standard. Multi-scale population pressure model is built to calculate the population pressure index in Three-gorge areas. The grain for green pressure index, a multivariate linear weighed model, is used to determine the spatial distribution of farmland fit for grain for green and fit for protecting.

    Challenges posed by changes in livestock production in emerging food producing areas and demographic development and climate change require new approaches and responsibilities in the management of food chains. The increasingly recognized role of primary food producers requires the support of the scientific community to instruct effective approaches based on scientific data, tools, and expertise. Mali is an emerging food producing area, and this review covers (i) the dairy farming scenario and its environment, (ii) the role of dairy production in food security, including the greatly different animal rearing systems in the Sahel and tropical regions, (iii) risk management pillars as modern infrastructures, effective farmer organizations, and institutional systems to guarantee animal health and safety of products, and (iv) feasible interventions based on good practices and risk assessment at the farm level (e.g., sustainable use of fertilizers, feeds, veterinary drugs, and pesticides) to protect consumers from food safety hazards. Social innovation based on the empowerment of the primary food producers emerges as crucial for sustainable and safe food production. Sustainable policies should be supported by the mobilization of stakeholders of One Health, which is a science-based approach to linking human health and nutrition with the health and management of food producing animals and environmental safety. In the context of the complex, multifaceted scenario of Mali dairy production, this article presents how a cost-effective animal health and food safety scheme could be established in the dairy production chain. Because milk is a major commodity in this country, benefits could be derived in food security, public health, the resilience of the farming system, animal husbandry, and international trade.

MÉTODOS: Os dados provêm da Pesquisa de Orçamentos Familiares da Fundação Instituto de Pesquisas Econômicas 1998/99, no Município de São Paulo. A influência da renda e do preço dos alimentos sobre a participação de frutas, legumes e verduras no total calórico foi estudada utilizando-se técnicas de análise de regressão para estimação de coeficientes de elasticidade. RESULTADOS: Observou-se aumento da participação de frutas, legumes e verduras no total de calorias adquirido com a diminuição de seu próprio preço, elevação da renda familiar, e aumento do preço dos demais alimentos. Um por cento da diminuição de preço das frutas, legumes e verduras aumentaria em 0,2% sua participação no total calórico; 1% de aumento do preço dos demais alimentos reduziria em 0,07%, a participação; 1% de aumento da renda familiar aumentaria em 0,04% a participação. O efeito dos preços dos demais alimentos perdeu intensidade nos estratos de maior renda, e nos outros dois casos não se identificou um padrão consistente de relação com os estratos de renda.

    Famine early warning organizations use data from multiple disciplines to assess food insecurity of communities and regions in less-developed parts of the World. In this paper we integrate several indicators that are available to enhance the information for preparation for and responses to food security emergencies. The assessment uses a price model based on the relationship between the suitability of the growing season and market prices for coarse grain. The model is then used to create spatially continuous maps of millet prices. The model is applied to the dry central and northern areas of West Africa, using satellite-derived vegetation indices for the entire region. By coupling the model with vegetation data estimated for one to four months into the future, maps are created of a leading indicator of potential price movements. It is anticipated that these maps can be used to enable early warning of famine and for planning appropriate responses.

    The mechanisms affecting housing prices were studied using the equilibrium housing prices based on classic supply/demand theory. The fluctuations of the actual housing prices were then analyzed relative to the equilibrium prices. The equilibrium prices for each area were calculated from economic statistics and housing prices in 35 China metropolitan areas. The fluctuations of the actual prices are then manifested as functions of the equilibrium price, the mean reversion, and the autocorrelation coefficient. The results show that the equilibrium prices are determined by the basic economic conditions in China and that the equilibrium prices greatly affect the fluctuation of the actual prices, which return to the equilibrium price through self-adjustments. The data also shows that the actual prices in China have the trend of continuing to rise in the future.

    Full Text Available Most studies on local rice in Nigeria were centred on increasing production, consumption or competitiveness with very few of them addressing the determinants of the price of rice in an economy. Filling this gap requires a study on the various factors that influence the price of rice. Food price instability is a frequent forerunner of macroeconomic shocks and political turmoil that can discourage long-run investment and curtail growth. In this study, secondary data were employed. The study used descriptive statistics tools to analyse the pattern of price variation over the period of 42 years in the study area. Similarly, various factors affecting price variation of rice were examined. The following recommendations were made: appropriate tax collection measures on producers should be implemented so as to curtail farmers from exploiting the masses by making excessive gains. Since the decrease in export results in an increase in price, the government should keep a balance between import and export to maintain the price of rice at a reasonable level. The price of rice can be reduced by the government when they implement measures to control the inflation rate in the economy. The government should put measures to regulate the quantity of land used by rice producers as well as to control the price of rice, since they both have a positive relationship.

    Food security in Sahelian countries strongly relies on the ability of markets to transfer staplesfrom surplus to deficit areas. Market failures, leading to the inefficient geographical allocation of food,are expected to emerge from high transportation costs and information asymmetries that are commonin moderately developed countries. As a result, important price differentials are observed betweenproducing and consuming areas which damages both poor producers and food insecure consumers. Itis then vital for policy makers to understand how the prices of agricultural commodities are formed byaccounting for the existing market imperfections in addition to local demand and supply considerations. To address this issue, we have gathered an unique and diversified set of data for Senegal andintegrated it in a spatially explicit model that simulates the functioning of agricultural markets, that isfully consistent with the economic theory. Our departure point is a local demand and supply modelaround each market having its catchment areas determined by the road network. We estimate the localsupply of agricultural commodities from satellite imagery while the demand is assumed to be a functionof the population living in the area. From this point on, profitable transactions between areas with lowprices to areas with high prices are simulated for different levels of per kilometer transportation costand information flows (derived from call details records i.e. mobile phone data). The simulated prices are then comparedwith the actual millet prices. Despite the parsimony of the model that estimates only two parameters, i.e. the per kilometertransportation cost and the information asymmetry resulting from low levels of mobile phone activitybetween markets, it impressively explains more than 80% of the price differentials observed in the 40markets included in the analysis. In one hand these results can be used in the assessment of the socialwelfare impacts of the further development of

    The raise in fossil fuels prices and the increase in Greenhouse Gas emissions is leading nations to adopt non-fossil fuels based energy sources. Sugarcane crops for biofuel production are expanding fast in Brazil, mainly through land use change (LUC) processes, in substitution of pasturelands and grain crops plantations. Would these changes affect negatively sustainability assessments of bioethanol production in the future? We estimate the extent of sugarcane cropland needed to produce sufficient ethanol to attend to market demands. This work presents a baseline scenario for sugarcane cropping area in Brazil in 2017, taking into account market forces (supply and demand). We also comment on a policy instrument targetting sustainable sugarcane production in Brazil. The expansion scenarios took into account the demand for ethanol from 2008-2017, produced by the Energy Research Corporation, of Brazil. In order to develop the expansion scenario, we estimated the amount of sugarcane needed to attend the ethanol demand. We then calculated the area needed to generate that amount of sugarcane. The analytical parameters were: 1) one tonne of sugarcane produces an average 81.6 liters of ethanol; 2) the average sugarcane crop productivity varied linearly from 81.4 tons/hectare in 2008 to 86.2 tons/hectare in 2017. We also assumed that sugarcane productivity in 2017 as the current average productivity of sugarcane in the State of São Paulo. The results show that the requirement for 3.5 million ha in 2007 will increase to 9 million ha in 2017. The Sugarcane Agroecologic Zoning (ZAECANA), published by Embrapa (2009), is a tool that not only informs the territory occupation and use policies, but also classifies land as qualified, restricted or non-qualified for the plantation of sugarcane crops. The ZAECANA is based on soil and climate suitability assessments, and is presented in a spatially-explicit format. Adopting the precautionary principle, a national policy was established

From detailed data on many price changes in all the monitoredstores we have evaluated, for example, how often the prices of specific items change or rise or fall, and byhow much on average, how these indicators change during the year, whether downwards price rigidityexists and so on.The average price change frequency for all the selected items came to 0.26, which means that approximatelyone in every four prices was changed compared to the month before. A typical characteristic of theprices of regulated items was that these prices mainly rose and this usually by steps of higher percentagesand mostly at the start of the year. Food prices had a higher frequency of price changes, mainly in the caseof unprocessed foods, which is a consequence of the volatile development of the prices of agricultural commodities.The prices of tradables excluding food and fuels continuously fell for the whole of the monitoredperiod and only had a low price change frequency. The prices of non-regulated non-tradables continuouslyand smoothly rose and, with the exception of hypothetical rent and package holidays, this subgroupdemonstrated the lowest frequency of price changes. The prices of fuels changed most frequently while onaverage these price changes were the lowest in size, as they react relatively quickly to changes in the pricesof raw materials and the koruna exchange rate.

    The potential of ecosystem engineers to modify the structure and dynamics of food webs has recently been hypothesised from a conceptual point of view. Empirical data on the integration of ecosystem engineers and food webs is however largely lacking. This paper investigates the hypothesised link based on a field sampling approach of intertidal biogenic aggregations created by the ecosystem engineer Lanice conchilega (Polychaeta, Terebellidae). The aggregations are known to have a considerable impact on the physical and biogeochemical characteristics of their environment and subsequently on the abundance and biomass of primary food sources and the macrofaunal (i.e. the macro-, hyper- and epibenthos) community. Therefore, we hypothesise that L. conchilega aggregations affect the structure, stability and isotopic niche of the consumer assemblage of a soft-bottom intertidal food web. Primary food sources and the bentho-pelagic consumer assemblage of a L. conchilega aggregation and a control area were sampled on two soft-bottom intertidal areas along the French coast and analysed for their stable isotopes. Despite the structural impacts of the ecosystem engineer on the associated macrofaunal community, the presence of L. conchilega aggregations only has a minor effect on the food web structure of soft-bottom intertidal areas. The isotopic niche width of the consumer communities of the L. conchilega aggregations and control areas are highly similar, implying that consumer taxa do not shift their diet when feeding in a L. conchilega aggregation. Besides, species packing and hence trophic redundancy were not affected, pointing to an unaltered stability of the food web in the presence of L. conchilega.

    Full Text Available Abstract Background Fast food restaurants reportedly target specific populations by locating in lower-income and in minority neighborhoods. Physical proximity to fast food restaurants has been associated with higher obesity rates. Objective To examine possible associations, at the census tract level, between area demographics, arterial road density, and fast food restaurant density in King County, WA, USA. Methods Data on median household incomes, property values, and race/ethnicity were obtained from King County and from US Census data. Fast food restaurant addresses were obtained from Public Health-Seattle & King County and were geocoded. Fast food density was expressed per tract unit area and per capita. Arterial road density was a measure of vehicular and pedestrian access. Multivariate logistic regression models containing both socioeconomic status and road density were used in data analyses. Results Over one half (53.1% of King County census tracts had at least one fast food restaurant. Mean network distance from dwelling units to a fast food restaurant countywide was 1.40 km, and 1.07 km for census tracts containing at least one fast food restaurant. Fast food restaurant density was significantly associated in regression models with low median household income (p Conclusion No significant association was observed between census tract minority status and fast food density in King County. Although restaurant density was linked to low household incomes, that effect was attenuated by arterial road density. Fast food restaurants in King County are more likely to be located in lower income neighborhoods and higher traffic areas.

    Full Text Available The crops that we grow for food need specific climatic conditions to show better performance in view of economic yield. A changing climate could have both beneficial and harmful effects on crops. Keeping the above view in mind, this study is undertaken to investigate the impacts of climate change (viz. changes in maximum temperature, minimum temperature, rainfall, humidity and sunshine on the yield and cropping area of four major food crops (viz. Aus rice, Aman rice, Boro rice and wheat in Bangladesh. Heteroskedasticity and autocorrelation consistent standard error (HAC and feasible generalized least square (FGLS methods were used to determine the climate-crop interrelations using national level time series data for the period of 1972–2010. Findings revealed that the effects of all the climate variables have had significant contributions to the yield and cropping area of major food crops with distinct variation among them. Maximum temperature statistically significantly affected all the food crops’ yield except Aus rice. Maximum temperature also insignificantly affected cropping area of all the crops. Minimum temperature insignificantly affected Aman rice but benefited other three crops’ yield and cropping area. Rainfall significantly benefitted cropping area of Aus rice, but significantly affected both yield and cropping area of Aman rice. Humidity statistically positively contributed to the yield of Aus and Aman rice but, statistically, negatively influenced the cropping area of Aus rice. Sunshine statistically significantly benefitted only Boro rice yield. Overall, maximum temperature adversely affected yield and cropping area of all the major food crops and rainfall severely affected Aman rice only. Concerning the issue of climate change and ensuring food security, the respective authorities thus should give considerable attention to the generation, development and extension of drought (all major food crops and flood (particularly Aman

    2013-11-01

    This paper investigated the role of grocery store prices in structuring food access for low-income households in Portland, Oregon. We conducted a detailed healthful foods market basket survey and developed an index of store cost based on the USDA Thrifty Food Plan. Using this index, we estimated the difference in street-network distance between the nearest low-cost grocery store and the nearest grocery store irrespective of cost. Spatial regression of this metric in relation to income, poverty, and gentrification at the census tract scale lead to a new theory regarding food access in the urban landscape. Food deserts are sparse in Portland, but food mirages are abundant, particularly in gentrifying areas where poverty remains high. In a food mirage, grocery stores are plentiful but prices are beyond the means of low-income households, making them functionally equivalent to food deserts in that a long journey to obtain affordable, nutritious food is required in either case. Results suggested that evaluation of food environments should, at a minimum, consider both proximity and price in assessing healthy food access for low-income households.

    AIM: This paper aims to develop a data-based semiquantitative food frequency questionnaire (SQFFQ) covering both urban and rural areas in the Chaoshan region of Guangdong Province, China, for the investigation of relationships between food intake and lifestyle-related diseases among middle-aged Chinese.METHODS: We recruited 417 subjects from the general population and performed an assessment of the diet, using a 3-d weighed dietary record survey. We employed contribution analysis (CA) and multiple regression analysis (MRA) to select food items covering up to a 90% contribution and a 0.90 R2, respectively. The total number of food items consumed was 523 (443 in the urban and 417 in the rural population) and the intake of 29 nutrients was calculated according to the actual consumption by foods/recipes.RESULTS: The CA selected 233, 194, and 183 foods/recipes for the combined, the urban and the rural areas, respectively,and then 196, 157, and 160 were chosen by the MRA. Finally,125 foods/recipes were selected for the final questionnaire.The frequencies were classified into eight categories and standard portion sizes were also calculated.CONCLUSION: For adoption of the area-specific SQFFQ,validity and reproducibility tests are now planned to determine how the combined SQFFQ performs in actual assessment of disease risk and benefit.

    2014-05-01

    Extreme poverty in Burundi's rural area and tensions between families with limited access to arable land hinder development towards a more stable and peaceful society. Due to these tensions and a rapid population growth, agricultural land is currently subject to increased degradation and low agricultural productivity. A whole range of other limiting factors contributes to this, such as: poor seed quality, poor nutrient management combined with low soil fertility, inadequate agronomic practices, pests and crop diseases, poorly developed supply chains, health problems, difficult access to credit, and insecurity. Solving one of these problems will not solve the chain that eventually leads to low food production; it will simply move the emphasis to the next constraining factor. An integrated rural development approach is therefore required to break this vicious circle. The project Fanning the Spark, a Public-Private-Partnership between Achmea Foundation, Alterra of Wageningen University and Research Centre, and HealthNet-TPO in Burundi started in September 2013 with an intervention in several rural villages in Gitega. The project's objective is to increase food production at village level, by means of investments in crop production, a family (income) insurance package that protects rural families against the financial consequences of catastrophic events (natural and health) and making micro-credits available. This will enhance farmers' workability and generate income from agricultural activities in order to break the poverty cycle and enhance food security. The insurance package comprises agricultural and health insurances, and will be jointly implemented with the sustainable agriculture component. The latter component focuses on Integrated Farm Management and the use of innovative soil management practices. Farmer-to-farmer training and scaling-up are crucial components, and in the first phase of the project "innovative farmer groups" have a central role in the

Effect of economical European crisis in food operators of corridor Tirana-Durres causing slightly increase of unemployment and increase of food prices. Our study has evaluated the unemployment situation and food retail prices using data analyzing methodology for three big food processing companies located in this area. From study results was concluded that unemployment is slightly increased a respectively was evaluated as following. For first company unemployment has been increased with 2, 8%, however for second company it was increased with 2, 1% and for third company it was increased with 1, 8%. Food retail prices produced by these companies are increased referring to food prices evaluated on 2009. Retail food prices are increased respectively for three food kinds. Beer retail prices produced by first company are increased with 3, 8%, dried sausages retail prices produced by second Company are increased with 2.5%. According to study results is confirmed also slightly increase of UHT milk product produced by third company with average value 1, 9%. Even thought there is no big difference between previous values for unemployment and retail prices in 2009 and results found in 2010-2011 confirmed that social impact of crises is evident because of increase of unemployment and food prices cause decrease of incomes for families living in Tirana and in Albania.

    Full Text Available BACKGROUND: Junk food simply means an empty calorie food; it lacks in micronutrients such as vitamins, minerals, or amino acids, and fibre but has high energy (calories. During school - age years, children begin to establish habits for eating and exercise that stick w ith them for their entire lives. If children establish healthy habits, their risk for developing many chronic diseases will be greatly decreased. The family, friends, schools, and community resources in a child’s environment reinforce lifestyle habits rega rding diet and activity. OBJECTIVES: To study the fast food consumptions pattern and fast food preferences among the school going children (9 - 13yrs and some of the determinants related to fast food consumption .

    2015-10-01

    In order to assess the qualitative pattern of food consumption in urban families of Anzoátegui, Venezuela, 300 domestic groups that combined a total of 1 163 people were studied. The domestic dietary pattern was addressed by the method of qualitative frequency of food consumption, which applied a structured survey that yielded the usual frequency of intake of a food or food group over a given period. The information was obtained through an interview with the person responsible for the procurement of food in every home, and included basic data for the socioeconomic and nutritional profile of the families studied. The qualitative analysis of the diet was obtained by comparing the different food groups that constitute the actual consumption pattern of the population studied, with official feeding guidelines suggested for the Venezuelan population. The present study showed that the qualitative pattern of food consumption in the urban population evaluated is characterized by slightly adjusted to the promotion of health and control of diet-related diseases. The family food proved to be far from the guidelines established by the dietary guidelines for Venezuela and consumption patterns are fairly homogeneous in the different socioeconomic strata. The foods most consumed daily were salt, coffee, dressing and precooked corn flour as well as beef, chicken and the higher weekly food consumption pastas. 90% of the food consumed daily is technologically processed. The results contribute to increase knowledge about the food situation of the Venezuelan population, and technically could direct the efforts of the authorities to reconcile the development of the productive sector and food supply, whereas a pattern qualitatively inadequate intake directly affects the individual biological functioning, and results in the collective conditioning of unfavorable health states.

  8. THE PRICE OF ONE SWEET CALORIE

    Sebastien Buttet

    2015-10-01

    Full Text Available We propose a new measure for food prices to further examine the impact of changes in food prices and real income on individuals’ eating decisions and weight. We calculate price per calorie for food consumed away from home and food consumed at home as the dollar amount spent by households on each food category divided by the number of calories consumed. We use our newly constructed time series for price per calorie as an input into a neoclassical model of eating decisions and weight. Our goal is to propose a quantitative explanation for the increase in calories consumed away from home as well as changes in weight for men and women 1971 and 2006. We find that prices determine the allocation of calories across food types, while income determines the total number of calories consumed and thus individuals' weight. Based on our results, we share the view that taxes on food will impact what people eat but will have limited effect on reducing the population body-mass index or the obesity prevalence

With flexible prices, we observe low prices and high quality in competitive (oligopolistic) markets, and high prices coupled with low quality in non-competitive...... (monopolistic) markets. We then introduce a regulated intermediate price above the oligopoly price and below the monopoly price. The effect in monopolies is more or less in line with standard intuition. As price falls volume increases and so does quality, such that overall efficiency is raised by 50%. However...

    Approximately 60% of U.S. children aged five and younger spend time in child-care settings. Such environments increase the risk of diarrheal disease, including diseases caused by enteric pathogens. To describe adherence to sanitation standards in classrooms and food preparation areas in child-care facilities, the authors conducted site visits in 40 North Carolina and South Carolina child-care facilities. Audits in up to two classrooms (rooms providing care for infants and toddlers) and the kitchen were performed using a form similar to a regulatory inspection form. Audit data were used to calculate indices to describe adherence to sanitation standards and were based on state environmental health regulations for child-care centers, the Food and Drug Administration's Food Code 2009, and guidance from food safety experts. Most facilities participating in the authors' study adhered to sanitation standards within the classroom; however, deficiencies with regard to sanitation in food preparation areas and refrigerator operating temperatures were noted. These results provide insight into possible risk factors for enteric disease transmission in child-care facilities.

    Full Text Available Background: Food consumption patterns of young children in China are not well known. Objective: Characterised food groups consumed by infants and young children in urban China using data from the Maternal Infant Nutrition Growth (MING study. Design: One 24-h dietary recall was completed for 1,350 infants and young children (436 infants aged 6–11 months and 914 young children aged 12–35 months, who were recruited from maternal and child care centres in eight cities via face-to-face interviews with the primary caregiver. All foods, beverages and supplements reported were assigned to one of 64 food groups categorised into the following: milk and milk products, grains, vegetables, fruits, protein foods and desserts/sweets. The percentage of infants and young children consuming foods from specific food groups was calculated, regardless of the amount consumed. Results: Less than half of infants consumed breast milk (47%, whereas 59% of infants consumed infant formula and 53–75% of young children consumed growing-up (fortified milk. Rice was the number one grain food consumed after 6 months (up to 88% and the consumption of infant cereal was low. About 50% of infants did not consume any fruits or vegetables, and 38% of young children did not consume any fruits on the day of the recall. Only 40% of all children consumed dark green leafy vegetables and even fewer consumed deep yellow vegetables. Eggs and pork were the most commonly consumed protein foods. Conclusions: The data provide important insight for developing detailed food consumption guidelines for this population group. Mothers of infants should be encouraged to continue breastfeeding after the first 6 months. Parents should be advised to offer a wide variety of vegetables and fruits daily, particularly dark green leafy and deep yellow vegetables and colourful fruits. The consumption of fortified infant cereal should be advocated to improve the iron intake of Chinese infants.

  17. Review of arsenic contamination and human exposure through water food in rural areas in Vietnam

    Energy Technology Data Exchange (ETDEWEB)

    Hahn, Celia

    2016-05-01

    The Red River Delta in Vietnam is one of the regions whose quaternary aquifers are polluted by arsenic. Chronic toxification by arsenic can cause severe illnesses such as cancer, skin lesions, developmental defects, cardiovascular and neurological diseases, and diabetes. In this study, a food processing craft village in the Red River Delta was investigated regarding the potential risk faced by the population due to arsenic. The potential sources of arsenic are the groundwater, the crops grown in the surroundings, and animal products from local husbandry. However, the occurrence of arsenic in nature is variable, and its bioavailability and toxicity depend very much on its specification: trivalent compounds are more toxic and often more mobile than pentavalent compounds, while inorganic species are generally more toxic than organic ones. Local conditions, such as the redox potential, strongly influence its specification and thus potential bioavailability. The introduction to this work elucidates the key factors which potentially cause human exposure to arsenic: the geological setting of the study area, land and water use patterns, and the current state of research regarding the mobilization, bioavailability and plant uptake of arsenic. Although the study area is located in a region where the groundwater is known to be moderately contaminated by arsenic, the level of arsenic in the groundwater in the village had not previously been determined. In this study, water use in the village was examined by a survey among the farmers and by water analyses, which are presented in the following chapters. Four main water sources (rain, river, tube well and a public municipal waterworks) are used for the different daily activities; the highest risk to human health was found to be the bore well water, which is pumped from the shallow Holocene aquifer. The water from the bore wells is commonly used for cleaning and washing as well as to feed the animals and for food processing

    Full Text Available The historical evidence suggests a high correlation between changes in the stock of money per unit of output and changes in prices in the same direction. The goal of this paper is to analyze the correlation between the monetary aggregates and the price stability before, during and after the financial and debt crisis in the European Monetary Union. For this purpose, firstly, the paper includes some basic theoretical aspects, secondly, practical analysis based on the Pearson product-moment correlation coefficient as a degree of the dependence between the monetary aggregate M3 and the harmonized index of consumer prices. The main task of the present paper is, accordingly, to consider, if there is any relationship between these variables, and whether there is any substantial reason for modifying the current mainstream mode of the policy analysis. The data were obtained from the data warehouses of the European Central Bank and the Statistical Office of the European Community (Eurostat. The obtained data were split up into 4 segments by the timetable of the period before the crisis, during the first and the second stage of the crisis and after the crisis. The base for the analysis was the quantitative theory of money, which states that money supply has the direct, proportional relationship with the price level. In general, we were able to identify the existence of very strong dependency between the content of monetary aggregate M3 and the price level measured by HICP, especially in the case when the data were not influenced by the seasonal aspects and within the delay of one month. It means that the transmission of monetary policy of ECB reacted relatively fast. On the other hand, the rapidity of transmission of monetary policy and its effectiveness is still not at the same level as it was in the period before the crisis and the influence of the crisis is still strongly visible.

  19. Higher prices in Jamaica.

    1982-03-01

    Price increases in the Jamaica CSM program went into effect on August 31, 1981. The program began in 1975. While the need for higher prices has been under discussion for the past 3 years, this is the 1st time the requisite approval from the Jamaica Price Commission has been obtained. The Jamaica National Family Planning Board (JNFPB) reports that the Panther 3-pack (condom) is up US$0.15 to US$0.30. Each Perle package (oral contraceptive) was increased by US$0.20. Single cycle Perle now sells for US$0.50, and 3-pack Perle sells for US$1.10. The 6-year price stagnation experienced by the CSM program resulted in a decreasing operational budget as program costs continued to rise. Marketing costs alone during this period escalated by 100-300%. For example, Panther pop-up display cartons cost the project US 16U each in 1975. By 1979 the same product cost US 49U. Newspaper advertisements have increased from the 1975 cost of US$68.00 to nearly $200.00 per placement. The overall inflation rate in Jamaica during the last 5 years has averaged more than 20% annually. In the face of these rising costs, outlet expansion for Perle has been prevented, wholesaler margins have been unavailable, and new retailer training has been discontinued. It is projected that the new prices will result in an annual increased revenues of US$80,000 which will be used to reinstate these essential marketing activities. The JNFPB is also planning to introduce a Panther 12-pack and Panther strips to the CSM product line. According to Marketing Manager Aston Evans, "We believe the public is now ready for this type of packaging" which is scheduled to be available soon. Panther is presently only available in a 3-pack, but annual sales have been steady. The new 12-pack will be stocked on supermarket shelves to provide higher product visibility and wider distribution. The selling price has been set as US$1.20 and is expected to yield a 25% increase in sales during the 1st year. A complete sales promotion

    We studied the composition, density, size distribution and biomass of the food supply for waders in an estuarine area in the Bay of Cádiz (SW Iberian Peninsula), in winter (January-February) and in the pre-migratory period (late March). The estuarine area comprises an intertidal mudflat and an adjacent salina or salt-pan. On the intertidal mudflat, the biomass was 53 and 37 g AFDW .m -2in winter and the pre-migratory period, respectively. The main food source on mudflat was the polychaete Nereis diversicolor (44-54 % of the total biomass). On the other hand, the biomass in the salina was comparatively very poor, ranging from 0.008 to 0.079 g AFDW .m -2in winter and ranging from 0.011 to 0.09 g AFDW in late March. The main source of food in the salina was the crustacean Artemia. The total biomass on the mudflat during the pre-migratory period was 1.4 times lower than in February. This depletion could be caused by wader predation, mainly by Nereis diversicolor consumption. Although the potential food on the mudflats could allow high intertidal densities of waders, the availability of high tide foraging areas in the salina seems to contribute to the maintenance of these high intertidal densities.

    Since 1987, successive framework programmes have contributed to strengthen European food research through the establishment of networks between research institutions, universities and companies from various European countries. In the FAIR programme (1994-1998), 118 research projects comprising nearly 1,000 participants from the European Union and Associated States have been supported in the food area with a European funding of about [symbol: see text] 108 million. Within the Quality of Life and Management of Living Resources programme (1998-2002), food research is mostly supported within the key action 'food, nutrition and health' with a budget of [symbol: see text] 290 million. After the first four deadlines, 735 eligible research proposals have already been received. Further to their evaluation by a panel of independent experts, 108 proposals have been funded or selected for funding representing a total contribution of about [symbol: see text] 168 million. Among those, several clusters of projects are now running on important topics such as probiotics, coeliac diseases, mycotoxins, GMO, safety and food for the elderly. In addition, technology stimulation measures are largely benefiting SMEs to foster their innovation potential. In January 2000, the European Commission adopted a Communication entitled "Towards the European Research Area (ERA)" with the objective to contribute to developing better framework conditions for research in Europe. On 21 February 2001, the Commission adopted proposals to be submitted to the European Parliament and Council for the next framework programme for research and innovation (2002-2006). The new framework programme that is becoming one of the financial instruments of the ERA aims at catalysing the integration of European research by: strengthening of links between the Community research effort and national and regional research policies; concentrating on a limited number of priority fields or research to which activities at the

    Full Text Available Broiler breeders (parents of meat chickens are selected for fast growth and become obese if fed ad libitum. To avoid this and maintain good health and reproductive ability, they are feed restricted to about 1/3 of what they would eat ad libitum.

    In the transitional period of " new normal",the target price is put forward to deepen the reform system of agricultural product price. Egg is the main agricultural product and its price has fluctuated violently in recent years. Setting up a target price for egg will reduce the price fluctuations. This article brings up a three-step agricultural price forecasting model based on EEMD and applies it to the analysis of egg price. It shows that the upward trend can be divided into three stages,and the fluctuation is greater than that of food consumer price in the foreseeable future. The volatility of egg price is bad for the development of the fresh market and stable life of the residents. This article finally puts forward some recommendations.

    Highlights: • Study of waste management in economically and socially deprived high-density housing. • Food waste segregation, prevention and recycling activities investigated. • Study involved a waste audit and household survey of 1034 households. • Populations in such areas are “hard-to-reach”. • Exceptional efforts and additional resources are required to improve performance. - Abstract: A waste audit and a household questionnaire survey were conducted in high-density housing estates in one of the most economically and socially deprived areas of England (Haringey, London). Such areas are under-represented in published research. The study examined source segregation, potential participation in a food waste segregation scheme, and food waste prevention activities in five estates (1034 households). The results showed that: contamination of recyclables containers was low; ca. 28% of the mixed residual waste’s weight was recyclable; food waste comprised a small proportion of the waste from these residents, probably because of their relatively disadvantaged economic circumstances; and the recycling profile reflected an intermittent pattern of behaviour. Although the majority of respondents reported that they would participate in a food waste separation scheme, the response rate was low and many responses of “don’t know” were recorded. Municipalities committed to foster improved diversion from landfill need to recognise that there is no “quick and easy fix”, regardless of local or national aspirations. Lasting and sustained behaviour change requires time and the quality of service provision and associated infrastructure play a fundamental role in facilitating residents to participate effectively in waste management activities that maximise capture of source-segregated materials. Populations in deprived areas that reside in high-rise, high-density dwellings are “hard-to-reach” in terms of participation in recycling schemes and exceptional

    Full Text Available The study simulated effects of paddy price support withdrawal, as an alternative policy, on key variables namely domestic rice supply, domestic rice demand, net import of rice, area planted to paddy and paddy producer price. Time series data (1980-2012 were collected and analyzed using Autoregressive Distributed lag (ARDL. The long run coefficients or elasticities generated were used in scenarios simulation through appropriate simulation technique. The results show that, on the average, paddy price support withdrawal would affect the rice sector by 2020 in the following ways: 13% decline in domestic rice production; 23% increase in net rice import; area planted to paddy decrease in size by 13%; and, paddy producer price reduce by 20%. However, there was no effect on aggregate rice consumption. Since the country is concern about raising farm income and ensuring rice food security, sustaining the paddy support price is worthwhile policy in order to avoid a decline in paddy producer price (income and surge in import bills.

    The objective of this study was to investigate the food habits of a representative sample of 651 rural school-age children from Chile's Metropolitan Region and to carry out a comparative study between 1986-1987 and 1989. Food habits were defined as the frequency of consumption of foods expressed as days per week and were determined through a questionnaire administered to school-age children by the investigators and were compared with Model Allowance, established by Chile's Ministry of Health. Socioeconomic status (SES) was measured through Graffar's modified method. Statistical procedures included analysis of variance and student "t" test for comparison of the means. The frequency of consumption of most food decreased in 1989 compared with 1986-1987. Most consumed foods (above 90%) were bread and potatoes and between 70-75% of the school-age children consumed milk, meat, yoghurt, poultry, eggs, beans, onions, cabbage, squash, lettuce, bananas, oranges, apples, grapes, biscuits, spaghetti, rice, oil, butter, carbonated beverages and juices, candies, sugar and chocolate. Foods most disliked were fresh cheese (69.3%), radish (62.2%), shellfish (59.4%) and chickpeas (48.8%). Males presented a frequency of consumption of beans, chickpeas (p < 0.05), lentil and chard swiss (p < 0.01) significantly higher than females, but these last ones registered a frequency of consumption of apples, cookies, oil (p < 0.05), onions and candies (p < 0.01) significantly higher than males. The frequency of consumption of most foods, especially milk, fish and bread (p < 0.01) decreased with age. SES had no effect on food habits of the school-age children. These results could be useful in the School Feeding Program (PAE) and in nutrition education related to school population.

    Full Text Available Abstract Background Changing lifestyles have recently caused a severe reduction of the gathering of wild food plants. Knowledge about wild food plants and the local environment becomes lost when plants are no longer gathered. In Central Europe popular scientific publications have tried to counter this trend. However, detailed and systematic scientific investigations in distinct regions are needed to understand and preserve wild food uses. This study aims to contribute to these investigations. Methods Research was conducted in the hill country east of Graz, Styria, in Austria. Fifteen farmers, most using organic methods, were interviewed in two distinct field research periods between July and November 2008. Data gathering was realized through freelisting and subsequent semi-structured interviews. The culinary use value (CUV was developed to quantify the culinary importance of plant species. Hierarchical cluster analysis was performed on gathering and use variables to identify culture-specific logical entities of plants. The study presented was conducted within the framework of the master's thesis about wild plant gathering of the first author. Solely data on gathered wild food species is presented here. Results Thirty-nine wild food plant and mushroom species were identified as being gathered, whereas 11 species were mentioned by at least 40 percent of the respondents. Fruits and mushrooms are listed frequently, while wild leafy vegetables are gathered rarely. Wild foods are mainly eaten boiled, fried or raw. Three main clusters of wild gathered food species were identified: leaves (used in salads and soups, mushrooms (used in diverse ways and fruits (eaten raw, with milk (products or as a jam. Conclusions Knowledge about gathering and use of some wild food species is common among farmers in the hill country east of Graz. However, most uses are known by few farmers only. The CUV facilitates the evaluation of the culinary importance of species and

    Statistical methods based on item response theory are applied to experiential food insecurity survey data from 147 countries, areas, and territories to assess data quality and develop methods to estimate national prevalence rates of moderate and severe food insecurity at equal levels of severity across countries. Data were collected from nationally representative samples of 1,000 adults in each country. A Rasch-model-based scale was estimated for each country, and data were assessed for consistency with model assumptions. A global reference scale was calculated based on item parameters from all countries. Each country's scale was adjusted to the global standard, allowing for up to 3 of the 8 scale items to be considered unique in that country if their deviance from the global standard exceeded a set tolerance. With very few exceptions, data from all countries were sufficiently consistent with model assumptions to constitute reasonably reliable measures of food insecurity and were adjustable to the global standard with fair confidence. National prevalence rates of moderate-or-severe food insecurity assessed over a 12-month recall period ranged from 3 percent to 92 percent. The correlations of national prevalence rates with national income, health, and well-being indicators provide external validation of the food security measure.

    Most research into cost systems has focused on their motivational implications. This paper takes a different approach, by developing a model where two oligopolistic firms strategically select their cost-based transfer prices. Duopoly models frequently assume that firms game on their choice of prices. Product prices, however, are ultimately based on the firms' transfer prices that communicate manufacturing costs to marketing departments. It is for this reason that transfer prices will have a s...

  16. Nonlinear Pricing in Energy and Environmental Markets

    Science.gov (United States)

    Ito, Koichiro

    This dissertation consists of three empirical studies on nonlinear pricing in energy and environmental markets. The first investigates how consumers respond to multi-tier nonlinear price schedules for residential electricity. Chapter 2 asks a similar research question for residential water pricing. Finally, I examine the effect of nonlinear financial rewards for energy conservation by applying a regression discontinuity design to a large-scale electricity rebate program that was implemented in California. Economic theory generally assumes that consumers respond to marginal prices when making economic decisions, but this assumption may not hold for complex price schedules. The chapter "Do Consumers Respond to Marginal or Average Price? Evidence from Nonlinear Electricity Pricing" provides empirical evidence that consumers respond to average price rather than marginal price when faced with nonlinear electricity price schedules. Nonlinear price schedules, such as progressive income tax rates and multi-tier electricity prices, complicate economic decisions by creating multiple marginal prices for the same good. Evidence from laboratory experiments suggests that consumers facing such price schedules may respond to average price as a heuristic. I empirically test this prediction using field data by exploiting price variation across a spatial discontinuity in electric utility service areas. The territory border of two electric utilities lies within several city boundaries in southern California. As a result, nearly identical households experience substantially different nonlinear electricity price schedules. Using monthly household-level panel data from 1999 to 2008, I find strong evidence that consumers respond to average price rather than marginal or expected marginal price. I show that even though this sub-optimizing behavior has a minimal impact on individual welfare, it can critically alter the policy implications of nonlinear pricing. The second chapter " How Do

    Full Text Available Introduction: Risk is an essential component in the production and sale of agricultural products. Due to the nature of agricultural products, the people who act in this area including farmers and businesspersons encounter unpredictable fluctuations of prices. On the other hand, the firms that process agricultural products also face fluctuation of price of agricultural inputs. Given that the Canola is considered as one of the inputs of product processing factories, control of unpredictable fluctuations of the price of this product would increase the possibility of correct decision making for farmers and managers of food processing industries. The best available tool for control and management of the price risk is the use of future markets and options. It is evident that the pricing is the main pillar in every trade. Therefore, offering a fair price for the options will be very important. In fact, options trading in the options market create cost insurance stopped. In this way, which can reduce the risks of deflation created in the future, if the person entitled to the benefits of the price increase occurs in the future. Unlike the futures, market where the seller had to deliver the product on time, in the options market, there is no such compulsion. In addition, this is one of the strengths of this option contract, because if there is not enough product for delivery to the futures market as result of chilling, in due course, the farmers suffer, but in the options market there will be a loss. In this study, the setup options of rape, as a product, as well as inputs has been paid for industry. Materials and Methods: In this section. The selection criteria of the disposal of asset base for valuation of European put options and call option is been introduced. That for obtain this purpose, some characteristics of the goods must considered: 1-Unpredictable fluctuations price of underlying asset 2 -large underlying asset cash market 3- The possibility

    Full Text Available OBJECTIVE: To identify the association between food group consumption frequency and serum lipoprotein levels among adults. METHODS: The observations were made during a cross-sectional survey of a representative sample of men and women over 20 years old living in Cotia county, S. Paulo, Brazil. Data on food frequency consumption, serum lipids, and other covariates were available for 1,045 adults. Multivariate analyses adjusted by age, gender, body mass index, waist-to-hip ratio, educational level, family income, physical activity, smoking, and alcohol consumption were performed. RESULTS: Consumption of processed meat, chicken, red meat, eggs and dairy foods were each positively and significantly correlated with LDL-C, whereas the intake of vegetables and fruits showed an inverse correlation. Daily consumption of processed meat, chicken, red meat, eggs, and dairy foods were associated with 16.6 mg/dl, 14.5 mg/dl, 11.1 mg/dl, 5.8 mg/dl, and 4.6 mg/dl increase in blood LDL-C, respectively. Increases of daily consumption of fruit and vegetables were associated with 5.2 mg/dl and 5.5 mg/dl decreases in LDL-C, respectively. Alcohol beverage consumption showed a significant positive correlation with HDL-C. CONCLUSIONS: Dietary habits in the study population seem to contribute substantially to the variation in blood LDL and HDL concentrations. Substantially CHD risk reduction could be achieved with dietary changes.

    Limited literature exists on toxaphene contamination in food worldwide, particularly in mainland China. In this study, three toxaphene congeners, Parlar 26 (B8-1413), Parlar 50 (B9-1679) and Parlar 62 (B9-1025), were analyzed in five different food categories from the Pearl River Delta Area in China using isotope dilution high-resolution gas chromatography/high-resolution mass spectrometry (HRGC/HRMS), and toxaphene levels in food were reported and toxaphene dietary intake by local residents estimated. The results showed that fish contained the highest toxaphene level with a median of 12.87 pg/g wet weight (ww), followed by poultry meat, egg products, livestock meat and vegetable, which had median levels of 5.8, 2.2, 1.89 and 0.67 pg/g ww, respectively. Parlar 50 and Parlar 26 were the predominant characteristic congeners in fish, and Parlar 26 was the predominant congener not only in poultry products and eggs, but also in livestock and vegetable. The estimated average daily intake found by local residents was 35.57 pg/kg body weight/day. Overall toxaphene levels and estimated dietary intake in the Pearl River Delta Area of South China are far lower than the European Maximum Residue Limits (EU MRLs), the German MRL for fish, and other international literature data. Therefore, the risk of adverse health effects from dietary intakes of toxaphene for the local residents is not considerable at the current time, but follow-ups are warranted to study dynamic changes of toxaphene in food in this area.

  11. Health benefits of 'grow your own' food in urban areas: implications for contaminated land risk assessment and risk management?

    LENUS (Irish Health Repository)

    2009-12-21

    Abstract Compelling evidence of major health benefits of fruit and vegetable consumption, physical activity, and outdoor interaction with \\'greenspace\\' have emerged in the past decade - all of which combine to give major potential health benefits from \\'grow-your-own\\' (GYO) in urban areas. However, neither current risk assessment models nor risk management strategies for GYO in allotments and gardens give any consideration to these health benefits, despite their potential often to more than fully compensate the risks. Although urban environments are more contaminated by heavy metals, arsenic, polyaromatic hydrocarbons and dioxins than most rural agricultural areas, evidence is lacking for adverse health outcomes of GYO in UK urban areas. Rarely do pollutants in GYO food exceed statutory limits set for commercial food, and few people obtain the majority of their food from GYO. In the UK, soil contamination thresholds triggering closure or remediation of allotment and garden sites are based on precautionary principles, generating \\'scares\\' that may negatively impact public health disproportionately to the actual health risks of exposure to toxins through own-grown food. By contrast, the health benefits of GYO are a direct counterpoint to the escalating public health crisis of \\'obesity and sloth\\' caused by eating an excess of saturated fats, inadequate consumption of fresh fruit and vegetables combined with a lack of exercise. These are now amongst the most important preventable causes of illness and death. The health and wider societal benefits of \\'grow-your-own\\' thus reveal a major limitation in current risk assessment methodologies which, in only considering risks, are unable to predict whether GYO on particular sites will, overall, have positive, negative, or no net effects on human health. This highlights a more general need for a new generation of risk assessment tools that also predict overall consequences for health to more effectively guide

    2015-03-01

    Full Text Available In this paper we are looking at the cause-effect relationship between the economic, financial, demographic and food crises. Crises are interrelated and need to be viewed together, as the effects of one crisis are or may represent causes for another crisis. The current food crisis translates today in food price increases, in the level of health of the population that does not have enough resources for a balanced diet and in obesity problems of the young generation (Romania ranks third among European countries. All these issues with immediate and direct effects over the population in our country have generated our interest to conduct a rigorous and careful observation on the development of the phenomenon of food crisis. Food crisis, its causes and consequences – aging population, the migration of the active population to other countries (especially from the rural areas and the agglomeration of the disadvantaged population in certain geographical areas, can cause social and economic imbalances.

    2001-09-01

    A survey was conducted through the SECUBA (SEguridad alimentaria en CUba y Buena Alimentación) research program in Cuban healthy smokers living in Guantánamo and in Havana. The aim of the survey was to investigate biological and nutritional factors connected with the occurrence of zero epidemic neuropathy (EN) observed in Guantánamo urban area since the disease emerged in Cuba. Blood riboflavin status and carotenoid and selenium concentrations were higher in Guantánamo than in Havana smokers. Food dietary quantities of plantain banana, pepper (Capsicum spp.), bovine meat and milk products were higher in Guantánamo. Inversely, foods rich in cholesterol, especially eggs, were more consumed in Havana. Through riboflavin, carotenoid and selenium contents and specific antioxidants substances (indoleamines, capsaicin), the foods more consumed in Guantánamo could be considered as EN protective factors. Disease protective effects could be exerted via enhancement of defence mechanisms against free radical damage and related mechanisms focused on redox recycling of glutathione and local protection from carotenoids. Finally, the results of the present study should help Cuba, through a better EN control, to improve long-term food safety and define healthier dietary habits.

  15. Public attitudes towards pricing policies to change health-related behaviours: a UK focus group study

    Marteau, Theresa M.; Kinmonth, Ann Louise; Cohn, Simon

    2015-01-01

    Background: Evidence supports the use of pricing interventions in achieving healthier behaviour at population level. The public acceptability of this strategy continues to be debated throughout Europe, Australasia and USA. We examined public attitudes towards, and beliefs about the acceptability of pricing policies to change health-related behaviours in the UK. The study explores what underlies ideas of acceptability, and in particular those values and beliefs that potentially compete with the evidence presented by policy-makers. Methods: Twelve focus group discussions were held in the London area using a common protocol with visual and textual stimuli. Over 300 000 words of verbatim transcript were inductively coded and analyzed, and themes extracted using a constant comparative method. Results: Attitudes towards pricing policies to change three behaviours (smoking, and excessive consumption of alcohol and food) to improve health outcomes, were unfavourable and acceptability was low. Three sets of beliefs appeared to underpin these attitudes: (i) pricing makes no difference to behaviour; (ii) government raises prices to generate income, not to achieve healthier behaviour and (iii) government is not trustworthy. These beliefs were evident in discussions of all types of health-related behaviour. Conclusions: The low acceptability of pricing interventions to achieve healthier behaviours in populations was linked among these responders to a set of beliefs indicating low trust in government. Acceptability might be increased if evidence regarding effectiveness came from trusted sources seen as independent of government and was supported by public involvement and hypothecated taxation.

    The variable incidence of primary liver cancer has been shown to be related to the average daily intake of aflatoxin in various parts of the world. This study was made to detect and report strategic points of contamination of foodstuffs in the region with the highest known incidence of liver cancer. Methods of food production, harvesting, storage and preparation were examined, and defects which promote fungus growth on food were found at each stage. Most meals consisted of a single dish with three basic ingredients -- a protein, bulk carbohydrate and green vegetables. Groundnuts were the main source of protein, but were also the main cause of aflatoxin contamination, since casual traditional methods of agriculture are not suited to the production of this exotic crop. Aflatoxin production appears to occur in the main sources of carbohydrate, such as cassava and maize, during storage. Leaves of various kinds provide substitutes for green vegetables and common methods of handling the crop promote fungal growth. Western-type foods had a particularly low aflatoxin content, or were free of it. Education and economic opportunities external to the subsistence economy structure are contributing to the westerisation of some living habits, a process believed to be responsible for the observed decrease in the incidence of primary liver cancer. Current knowledge indicates that a pertinent but simple educational programme could further markedly reduce the incidence of the disease.

    2014-01-01

    Based on the annual sample data on food production in China since the reform and opening up,we select 8 main factors influencing the total food production( growing area,application rate of chemical fertilizer,effective irrigation area,the affected area,total machinery power,food production cost index,food production price index,financial funds for supporting agriculture,farmers and countryside),and put them into categories of material input,resources and environment,and policy factors. Using the factor analysis,we carry out the multi-angle analysis of these typical influencing factors one by one through the time series trend chart. It is found that application rate of chemical fertilizer,the growing area of food crops and drought-affected area become the key factors affecting food production. On this basis,we set forth the corresponding recommendations for improving the comprehensive food production capacity.

    Full Text Available Following the political transformation of Hungary fundamental changes took place in the trading sector as a consequence of privatization. The influx of active capital considerably influenced the economy and due to its multiplying effects new enterprise management systems, new work comprehension, new service background were established to help the economy participants. Chain formation, trade companies and shopping centres having large floor-space moved into the area with their modern equipments and wide commodity assortment, assisted by foreign capital investment. At the same time national retail trade declined, micro enterprises with few employees lost their survival possibilities in the area. The reply of the food trade sector to the entry of well-capitalized enterprises in the area was that the “chain formation” of smaller retailers became more frequent in the last years in Hungary. This type of transformation made them capable of competing with the big companies.

    Reference price systems for prescription drugs have found widespread use as cost containment tools. Under such regulatory regimes, patients co-pay a fraction of the difference between pharmacy retail price of the drug and a reference price. Reference prices are either externally (based on drug...... prices in other countries) or internally (based on domestic drug prices) determined. In a recent study, we analysed the effects of a change from external to internal reference pricing in Denmark in 2005, finding that the reform led to substantial reductions in prices, producer revenues, and expenditures...... for patients and the health insurance system. We also estimated an increase in consumer welfare but the size effect depends on whether or not perceived quality differences between branded and other drugs are taken into account....

  1. Foods, macronutrients and fibre in the diet of blue sheep (Psuedois nayaur) in the Annapurna Conservation Area of Nepal.

    Food resources are often critical regulating factors affecting individual fitness and population densities. In the Himalayan Mountains, Bharal "blue sheep" (Pseudois nayaur) are the main food resource for the endangered snow leopard (Panthera uncia), as well as being preyed upon by other predators. Blue sheep, however, may face a number of challenges including food resource competition with other wild and domestic ungulates, and hunting pressure. Here, we characterized the diet of blue sheep in the Annapurna Conservation Area (ACA) of Nepal and conducted proximate nutritional analysis on a limited number of plants identified as foods. Furthermore, we investigated the macronutrient and fiber balance of these plants using nutritional geometry which is a state-space approach to modeling multidimensional and interactive nutritional aspects of foraging. A total of 19 plant species/genera were identified in blue sheep pellets using microhistological analysis. On average, across seasons and regions of the study area, the two most frequently occurring plants in pellets were graminoids: Kobressia sp. and Carex spp. The macronutrient balance of Kobresia sp. was relatively high in carbohydrate and low in protein, while other plants in the diet were generally higher in protein and lipid content. Analysis of fiber balance showed that the two most consumed plants of blue sheep (i.e., Kobresia spp. and Carex spp.) contained the highest concentration of hemicellulose, which is likely digestible by blue sheep. The hemicellulose and lignin balance of plants ranged relatively widely, yet their cellulose contents showed less variation. Foraging by blue sheep may therefore be a balance between consuming highly digestible high-carbohydrate plants and plants less-digestible but higher in protein and/or lipid.

    Socioeconomic disparities in the food environment are known to exist but with little understanding of change over time. This study investigated the density of takeaway food outlets and presence of supermarkets in Norfolk, UK between 1990 and 2008. Data on food retail outlet locations were collected from telephone directories and aggregated within electoral wards. Supermarket presence was not associated with area deprivation over time. Takeaway food outlet density increased overall, and was significantly higher in more deprived areas at all time points; furthermore, socioeconomic disparities in takeaway food outlet density increased across the study period. These findings add to existing evidence and help assess the need for environmental interventions to reduce disparities in the prevalence of unhealthy food outlets. PMID:25841285

    Polybrominated diphenyl ethers (PBDEs) are one class of brominated flame retardants (BFRs). Although studies have reported the occurrence of PBDEs in freshwater fish species from several locations, to our best knowledge, there was no comprehensive data on PBDEs in foods of animal origin, such as pork, egg, and milk samples from interior areas of China, where pork and eggs are the major constituents of diet. The levels of PBDEs (BDE-28, 47, 99, 100, 153, 154, and 183) were determined in samples of animal-derived foods widely consumed by the population of Hubei in east-central China and the middle reaches of the Yangtze River. Two hundred six samples of animal-derived foods were randomly acquired in 17 sites of Hubei in 2010. The highest medium concentration of ∑7PBDEs was found in chicken eggs (0.191 ng/g wet weight (ww)), followed by duck eggs (0.176 ng/g ww), pork (0.050 ng/g ww), carps (0.047 ng/g ww), and cow milk (0.013 ng/g ww). The estimated dietary intake of Σ7PBDEs for a standard adult of 60 kg body weight based on medium and 95th percentile concentrations with consumption of animal-derived foods in Hubei province were 157.5 and 1960.3 pg/kg body weight/day, respectively. Chicken eggs (65.9 %) and pork (23.4 %) were the largest contributors to dietary intake of ∑7PBDEs through animal-derived foods. The same PBDE sources were exposed in Hubei province via principal component analysis (PCA), and the particular congener profile in samples of animal-derived foods revealed the possible exposure history of octa-BDEs and penta-BDEs in the local region. The large margins of exposure (MOE) calculated following the European Food Safety Authority (EFSA) approach for three important congeners, BDE-47, BDE-99, and BDE-153, indicated that the estimated dietary exposures were unlikely to be a significant health concern to in Hubei.

    Human exposure to brominated flame retardants (BFRs: decabromodiphenyl ether (BDE209), decabromodiphenyl ethane (DBDPE), hexabromobenzene (HBB), pentabromoethylbenzene (PBEB), pentabromotoluene (PBT), 1,2,3,4,5-pentabromobenzene (PBBz), and 2,3,5,6-tetrabromo-p-xylene (TBX)) in a brominated flame retardant production area (Weifang, Shandong Province, China) was estimated. Thirty food samples, 14 air samples, and 13 indoor dust samples were analyzed. BDE209 and DBDPE were the dominant BFRs in all samples. Higher alternative brominated flame retardant (including DBDPE, HBB, PBEB, PBT, PBBz, and TBX) concentrations were found in vegetables than in fish and meat; thus, plant-original foods might be important alternative BFR sources in the study area. The BDE209 and alternative BFR concentrations in air were 1.5×10(4) to 2.2×10(5) and 620 to 3.6×10(4) pg/m3, respectively. Mean total BFR exposures through the diet, inhalation, and indoor dust ingestion were 570, 3000, and 69 ng/d, respectively (16, 82, and 2% of total intake, respectively). Inhalation was the dominant BFR source except for DBDPE, for which diet dominated. BDE209 contributed 85% of the total BFR intake in the study area.

    Full Text Available Cadmium (Cd is ubiquitous in environment and may enter food chain through intense application of phosphate fertilizers to agricultural crops. A cross-sectional study was conducted at Kuala Terla and Blue Valley farming villages, Cameron Highlands to determine cadmium concentration in vegetables and soil and to determine the health risks among respondents. A total of 87 respondents were selected based on inclusive and exclusive criteria. A set of pre-tested questionnaires utilized to obtain socio-demographic information and to predict health risks faced by the respondents based on their vegetable ingestion rate. The Average Daily Dose (ADD and Target Hazard Quotient (THQ were determined in this study. Convenient sampling method was employed to obtain 15 paired soil and vegetable samples. Cadmium concentration in the samples was acid digested prior analysis using Flame Atomic Absorption Spectrophotometer (FAAS. The mean ± standard deviation concentrations of Cd in vegetable samples were 0.13±0.082 mg kg-1, within the acceptable range specified by Malaysia Food Regulation 1985 (1 mg kg-1. For sol samples, the mean ± standard deviation concentration of Cd was 2.78±2.83 mg kg-1. Eight out of 11 soil samples exceed the permissible limit of Cd outlined by The Dutch Standard (1 mg kg-1. The findings on THQ demonstrated that all respondents are within the acceptable non-carcinogenic health risk (THQ<1. The results also exhibit that there is no correlation between cadmium in soils and vegetables. There are unlikely potential adverse health impacts arising from Cd through vegetables consumption in this study. Respondents are advised to have a medical check-up in order to determine Cd body burden thus eliminating the risks of acquiring cadmium related diseases.

  13. Calculating proper transfer prices

    1991-01-01

    This article deals with developing a proper transfer pricing method. Decentralization is as American as baseball. While managers laud the widespread benefits of both decentralization and baseball, they often greet the term transfer price policy with a yawn. Since transfer prices are as critical to the success of decentralized firms as good pitchers are to baseball teams, this is quite a mistake on the part of our managers. A transfer price is the price charged to one division for a product or service that another division produced or provided. In many, perhaps most, decentralized organizations, the transfer pricing policies actually used are grossly inefficient and sacrifice the potential advantages of decentralization. Experience shows that far too many companies have transfer pricing policies that cost them significantly in foregone growth and profits.

Its incidence is increasing among Brazilian adults, including those living in rural areas. Our aim was not only to describe the frequency of MetS in adults with or without MetS but also to compare their food intake pattern as assessed by the healthy eating index (HEI and serum albumin and C reactive protein (CRP levels. METHODS: Men and women (n = 246 living in a small village in Brazil were included. MetS was characterized according to the adult treatment panel (ATP III criteria. Groups were compared by chi-square, student t or Mann-Whitney tests. RESULTS: MetS was diagnosed in 15.4% of the cases. The MetS group showed higher CRP (1.8±1.2 vs. 1.0±0.9 mg/dl and lower albumin (4.3±0.3 vs. 4.4±0.3 g/dl serum levels compared to the control group. Additionally, the MetS group showed lower scores (median[range] in the HEI compared to the control group (53.5[31.2-78.1] vs 58[29.7-89.5], respectively. The MetS group also had decreased scores for total fat and daily variety of food intake. CONCLUSIONS: The results suggest that adults with MetS displayed chronic mild inflammation and a poorer food intake pattern than the control group.

    The extent that neural responsiveness to visual food stimuli is influenced by time of day is not well examined. Using a crossover design, 15 healthy women were scanned using fMRI while presented with low- and high-energy pictures of food, once in the morning (6:30-8:30 am) and once in the evening (5:00-7:00 pm). Diets were identical on both days of the fMRI scans and were verified using weighed food records. Visual analog scales were used to record subjective perception of hunger and preoccupation with food prior to each fMRI scan. Six areas of the brain showed lower activation in the evening to both high- and low-energy foods, including structures in reward pathways (P foods compared to low-energy foods (P food stimuli tended to produce greater fMRI responses than low-energy food stimuli in specific areas of the brain, regardless of time of day. However, evening scans showed a lower response to both low- and high-energy food pictures in some areas of the brain. Subjectively, participants reported no difference in hunger by time of day (F = 1.84, P = 0.19), but reported they could eat more (F = 4.83, P = 0.04) and were more preoccupied with thoughts of food (F = 5.51, P = 0.03) in the evening compared to the morning. These data underscore the role that time of day may have on neural responses to food stimuli. These results may also have clinical implications for fMRI measurement in order to prevent a time of day bias.

  18. Transition from monopoly pricing to competitive pricing

    Energy Technology Data Exchange (ETDEWEB)

    1995-12-31

    The Victorian Government has embarked on a program to restructure the State electricity supply industry, that will be the precursor to reform throughout the whole of Australia. The Government is depending on competition to drive efficiency improvements to both generation and distribution businesses. Retail pricing will be the key determinant to a future assessment of the success or failure of these reforms. The paper examines electricity pricing before and after the restructuring from the viewpoint of a practitioner at the cutting edge of the reform process. Economic rationale is put forward why the Value Proposition will replace the Cost Recovery basis previously used in electricity pricing. It is concluded that limitations of interstate links will temper intestate competition unless innovative solution can be found. The current method of setting market prices based on a `Pool System` is only efficient if the generators bid their marginal price on a regular basis. In essence the pool replaces the `merit order` previously used to load generators and is basically a scheduling mechanism. Serious consideration needs to be given to the question whether this mechanism should be also setting the price of electricity. (author). 5 tabs.

    Full Text Available The paper reports results from an explorative research on the socio-economic opportunity that the presence of pilgrims and tourists along the Tuscan section of the Via Francigena can be for local communities. The aim is to deepen the actual and future opportunities that gastronomy represent for the development of tourism around the Via Francigena, with a special attention to destinations out of the beaten tracks. The research has been carried out merging different sources of information, including scientific literature, news, media, direct observation and personal experience, and performing a dozen of face-to-face interviews to key-informants, selected within socioeconomic actors involved in developing tourism around the course of the Via Francigena in Tuscany. The interviews have been carried out during the last six months, involving farmers, wine producers, restaurant owners, tourism and rural tourism entrepreneurs and local administrative offices. Local communities have already understood the strategic importance to sustain their socioeconomic activities with the development of pilgrimage and tourism along the Via Francigena. The rich variety of local gastronomy can satisfy both frugal needs of pilgrims and those of visitors more interested in gourmandizing. Food and gastronomy could be a strong leverage to increase tourist presences out of the beaten tracks.

    Full Text Available Native Papuans are relied on hunting for subsistence purposes and significantly contributed to traditional cultures. However, in Papua information on hunting is limited and largely restricted to anthropological setting with most observations were done on the forest sites in lowland and highland landscapes. This study focuses on the contribution of hunting on food security along the coastal forests at the Bird’s Head Peninsula. Do people live near coastal sites mostly rely on marine resources as protein source? We gathered data on hunting by the majority of Karon ethnic group in the Abun district of Tambrauw Regency at the Bird’s Head Peninsula of Papua, Indonesia. We used information from in-depth interviews with hunters and households meal survey at four villages of Abun: Waibem, Wau, Warmandi and Saubeba. Reasons for hunting were varies among respondents but mostly conducted for trade. Six species of mammals and three birds were commonly hunted by using six different hunting techniques. Wild pig and rusa deer were the major targets in hunting to meet the demand of meat for both trading and household consumption. Meals containing wildmeat was the most consumed meal, greater than meals containing fish, animal products and vegetables, and noodles.

  3. [The precautionary principle and its legal implications in the area of food safety].

    Science.gov (United States)

    Belvèze, H

    2003-08-01

    The concept of the 'precautionary principle' is not independent of the general principles of risk assessment and cannot be used as a justification for circumventing the legal obligations established at international level by World Trade Organization (WTO) agreements. On the contrary, the principle, which allows policy-makers to act without waiting until all the relevant scientific information is available, is included in the discipline established by the WTO Agreement on the Application of Sanitary and Phytosanitary Measures (SPS Agreement) and confirmed by jurisprudence. Sanitary measures adopted provisionally in a context of scientific uncertainty should nevertheless endeavour to comply with the general principles of risk management established by the SPS Agreement, i.e. they should be appropriate, non-discriminatory, consistent and not more trade-restrictive than required. The Codex Alimentarius has been working for several years to develop a set of principles for the application of risk assessment, including the precautionary principle when information is insufficient or incomplete. These principles will serve as a guide first for the work of the Codex and subsequently for governments. The European Union has made provision for the application of the precautionary principle, in accordance with circumstances, in Community food legislation, while remaining in compliance with the legal obligations stemming from the SPS Agreement.

    Food insecurity continues to be a major challenge in the United States, affecting 49 million individuals. Quantitative studies show that food insecurity has serious negative health impacts among individuals suffering from chronic illnesses, including people living with HIV/AIDS (PLHIV). Formulating effective interventions and policies to combat these health effects requires an in-depth understanding of the lived experience and structural drivers of food insecurity. Few studies, however, have elucidated these phenomena among people living with chronic illnesses in resource-rich settings, including in the United States. Here we sought to explore the experiences and structural determinants of food insecurity among a group of low-income PLHIV in the San Francisco Bay Area. Thirty-four semi-structured in-depth interviews were conducted with low-income PLHIV receiving food assistance from a local non-profit in San Francisco and Alameda County, California, between April and June 2014. Interview transcripts were coded and analysed according to content analysis methods following an inductive-deductive approach. The lived experience of food insecurity among participants included periods of insufficient quantity of food and resultant hunger, as well as long-term struggles with quality of food that led to concerns about the poor health effects of a cheap diet. Participants also reported procuring food using personally and socially unacceptable strategies, including long-term dependence on friends, family, and charity; stealing food; exchanging sex for food; and selling controlled substances. Food insecurity often arose from the need to pay high rents exacerbated by gentrification while receiving limited disability income--​a situation resulting in large part from the convergence of long-standing urban policies amenable to gentrification and an outdated disability policy that constrains financial viability.

    The objective of this study in the framework of the KErguelen Ocean and Plateau compared Study, 2005-2007 (KEOPS) project was to examine the microbial food web structure within a phytoplankton bloom induced by natural iron fertilization. Integrated bacterial production (BP, 0-100 m) varied 12-fold over the study area (23.5-304 mg C m -2 d -1), while bacterial abundance (0-100 m) varied only by a factor of 2.8. Highest bacterial abundances and rates of BP were observed in the center of the diatom-dominated bloom, and substantial decreases in BP towards the later bloom stage were detectable. The abundance of bacterial predators (heterotrophic nanoflagellates, HNF) showed a significant coupling with BP in the high-nutrient low-chlorophyll (HNLC) area only. In the core of the bloom, BP consumed by HNF was 27%, 29%, 52% and 34% during the four consecutive visits that extended over 4 weeks and was much higher (80-95%) in HNLC waters. The relative contribution of the small-sized (important within (224 mg C m -2, 0-100 m) than outside the bloom (30.5 mg C m -2, 0-100 m). This difference was attributable mainly to tintinnids Cymatocyclis spp. accounting for 30-80% of the total ciliate biomass within the Kerguelen bloom but being rare in the HNLC water. Mixotrophic ciliate biomass accounted for 40-60% of the total aloricate ciliate biomass all over the studied area. This was mainly due to the relatively large size of mixotrophic ciliates present in the samples ( Tontonia antarctica, Strombidium spp. and Laboea strobila). Overall, our results suggest a strong response of bacteria, weak response of HNF, and strong controlling effects on ciliates. The weak coupling between heterotrophic bacteria and HNF and the low abundance of ciliates suggest a low transfer of carbon from the microbial to the classical food web within the Kerguelen bloom.

    Full Text Available Populations of European ungulates have grown substantially over recent decades, resulting in considerable environmental and socio-economic impacts. Availability and quality of natural and supplemental food sources are among the main factors driving their population dynamics. Detailed knowledge of food quality of management-targeted species is therefore of primary importance for their successful management. The main aim of this study was to evaluate winter food quality and its variability for an important ungulate species in the Czech Republic - i.e. red deer, using faecal indices (faecal nitrogen, faecal acid detergent fibre, faecal neutral detergent fibre and near infrared reflectance spectroscopy. We compared food quality for red deer and its possible differences between overwintering enclosures (i.e. fenced areas where red deer spend harsh winter conditions and neighbouring unfenced free-ranging areas within two study areas. The results obtained showed that winter food quality and its variability for red deer are of different quality and variability in the overwintering enclosure and neighbouring free-ranging area. The observed differences in concentrations and amounts of variation of faecal indices are most probably related to animal densities at individual study areas. Wildlife managers should therefore keep animals in overwintering enclosures at moderate densities and to provide high quality forage to all individuals in order to balance nutrition of both the individuals inside and outside the enclosures. Nevertheless, further studies are needed in order to provide deeper knowledge on red deer food quality and its variability in space and time.

We compute a measure for target price forecast accuracy that evaluates the ability of analysts to exactly forecast the ex-ante (unknown 12-month stock price. Furthermore, we determine factors that explain this accuracy. Target price accuracy is negatively related to analyst-specific optimism and stock-specific risk (measured by volatility and price-to-book ratio. However, target price accuracy is positively related to the level of detail of each report, company size and the reputation of the investment bank. The potential conflicts of interests between an analyst and a covered company do not bias forecast accuracy.

    2008-01-01

    We study a multi-player one-round game termed Stackelberg Network Pricing Game, in which a leader can set prices for a subset of $m$ priceable edges in a graph. The other edges have a fixed cost. Based on the leader's decision one or more followers optimize a polynomial-time solvable combinatorial minimization problem and choose a minimum cost solution satisfying their requirements based on the fixed costs and the leader's prices. The leader receives as revenue the total amount of prices paid by the followers for priceable edges in their solutions, and the problem is to find revenue maximizing prices. Our model extends several known pricing problems, including single-minded and unit-demand pricing, as well as Stackelberg pricing for certain follower problems like shortest path or minimum spanning tree. Our first main result is a tight analysis of a single-price algorithm for the single follower game, which provides a $(1+\\epsilon) \\log m$-approximation for any $\\epsilon >0$. This can be extended to provide a ...

    Full Text Available This study examined the effects of climate change on food expenditure in rural household of Iran. Food expenditure is investigated as a function of average income of rural households, retail food price index and food expenditure for rural households, agricultural sown area and climate change. Here, the Stata11 software is used and data are from 26 provinces of the country for 10 years. Precipitation, temperature and relative humidity are considered as indicators for climate variables. The results indicated a positive and significant effect of average income of rural households, retail food prices, food expenditure of rural households with a lag and precipitation on the food expenditure of rural households. Agricultural sown area and relative humidity had no effect on the food expenditure of rural households and temperature had a significant and negative effect on the food expenditure of rural households. In the end, due to the impact that each of these variables explicitly have on food expenditure of rural households and implicitly on food security of rural households, suggestions for maintaining and improving food security of rural households is presented.

  18. A Price Hedging Model in Dynamic Market

    Directory of Open Access Journals (Sweden)

    Kuo-Wei Lin

    2012-01-01

    Full Text Available Problem statement: Pricing is a problem when a firm has to set a price for the first time. This happens when the firm develops or acquires a new product, introduces its regular product into a new distribution or geographical area, or enters bids on the new contract work. Many companies try to set the price to maximize current profits. They estimate the demand and costs associated with alternative prices and choose the price that maximizes current profit, cash flow, or rate of return on investment. There are, however, some problems associated with the current profit maximizing approach as it assumes that the firm knows its demand and cost functions; in reality, demand is difficult to estimate and is unpredictable. Approach: Due to demand’s unpredictability, we assume that it follows a lognormal random walk. Based on this, we develop a mathematical pricing processes model by stochastic calculus, which is similar to the financial process mathematical model. From Ito’s lemma, a product’s profit correlates with demand, is also unpredictable and follows a random walk. Such random behavior is the marketing risk. Results: By choosing a price strategy to eliminate randomness, called price hedging, we obtain risk-free profit determined by the Black-Scholes equation. This riskless profit, which is predictable, is the same we would get by putting the equivalent amount of cash in a risk-free interest-bearing account. Conclusion: From price hedging and the Black-Scholes equation, we determine the basic product price, which changes with time and demand.

It is also to identify the contribution of the granary areas in East Coast Economic Region (ECER to the national food security. The important of rice as a staple food crop of Malaysia and is grown on 673,745 ha of land, producing annually 2.6 million tons of paddy grain valued at RM 2 billion, which is contribute with average growth rate of 3.7% of year, in the last five years. However, the current country’s self-sufficiency level for rice production is about 71.4% and the balance imported from countries abroad. Efforts are being undertaken by government to increase the productivity, cropping intensity prediction and crop acreage to cope with the growing demand for the produce. This study examines the various issues of rice production for food security and analyses the challenging of rice production in Malaysia. Various policies, strategies and programmes for rice production will be thoroughly analysed for attaining the study objectives. In the ECER, Kemubu Agricultural Development Authority (KADA, Kemasin Semerak and North Terengganu (KETARA Integrated Agriculture Development Area (IADA is among the granary areas, which emphasised on paddy cultivation to the country. The role of the area is important to enhance the self-sufficiency level of rice in Malaysia. Issues and challenges related to rice production, food security and self-sufficiency are discussed. Various efforts and government intervention have been implemented to ensure that these areas will remain as the important granary area. Several approaches to improve the productivity and stability of food production as well as outlining the agenda to ensure the country food supply are discussed.

    Energy security issues coupled with increased concern over the natural environment are driving factors behind oil price movements. While it is widely accepted that rising oil prices are good for the financial performance of alternative energy companies, there has been relatively little statistical work done to measure just how sensitive the financial performance of alternative energy companies are to changes in oil prices. In this paper, a four variable vector autoregression model is developed and estimated in order to investigate the empirical relationship between alternative energy stock prices, technology stock prices, oil prices, and interest rates. Our results show technology stock prices and oil prices each individually Granger cause the stock prices of alternative energy companies. Simulation results show that a shock to technology stock prices has a larger impact on alternative energy stock prices than does a shock to oil prices. These results should be of use to investors, managers and policy makers. (author)

    A large and growing body of scientific evidence demonstrates that sugar drinks are harmful to health. Intake of sugar-sweetened beverages (SSB) is a risk factor for obesity and type 2 diabetes. Mexico has one of the largest per capita consumption of soft drinks worldwide and high rates of obesity and diabetes. Fiscal approaches such as taxation have been recommended as a public health policy to reduce SSB consumption. We estimated an almost ideal demand system with linear approximation for beverages and high-energy food by simultaneous equations and derived the own and cross price elasticities for soft drinks and for all SSB (soft drinks, fruit juices, fruit drinks, flavored water and energy drinks). Models were stratified by income quintile and marginality index at the municipality level. Price elasticity for soft drinks was -1.06 and -1.16 for SSB, i.e., a 10% price increase was associated with a decrease in quantity consumed of soft drinks by 10.6% and 11.6% for SSB. A price increase in soft drinks is associated with larger quantity consumed of water, milk, snacks and sugar and a decrease in the consumption of other SSB, candies and traditional snacks. The same was found for SSB except that an increase in price of SSB was associated with a decrease in snacks. Higher elasticities were found among households living in rural areas (for soft drinks), in more marginalized areas and with lower income. Implementation of a tax to soft drinks or to SSB could decrease consumption particularly among the poor. Substitutions and complementarities with other food and beverages should be evaluated to assess the potential impact on total calories consumed.

  11. Behavioral dimensions of food security.

    2012-07-31

    The empirical regularities of behavioral economics, especially loss aversion, time inconsistency, other-regarding preferences, herd behavior, and framing of decisions, present significant challenges to traditional approaches to food security. The formation of price expectations, hoarding behavior, and welfare losses from highly unstable food prices all depends on these behavioral regularities. At least when they are driven by speculative bubbles, market prices for food staples (and especially for rice, the staple food of over 2 billion people) often lose their efficiency properties and the normative implications assigned by trade theory. Theoretical objections to government efforts to stabilize food prices, thus, have reduced saliency, although operational, financing, and implementation problems remain important, even critical. The experience of many Asian governments in stabilizing their rice prices over the past half century is drawn on in this paper to illuminate both the political mandates stemming from behavioral responses of citizens and operational problems facing efforts to stabilize food prices. Despite the theoretical problems with free markets, the institutional role of markets in economic development remains. All policy instruments must operate compatibly with prices in markets. During policy design, especially for policies designed to alter market prices, incentive structures need to be compatible with respect to both government capacity (bureaucratic and budgetary) and empirical behavior on the part of market participants who will respond to planned policy changes. A new theoretical underpinning to political economy analysis is needed that incorporates this behavioral perspective, with psychology, sociology, and anthropology all likely to make significant contributions.

    Full Text Available The paper investigates the synchronization of price changes in the context of retail tire dealers in São Paulo-Brazil and selected items in supermarkets for cleaning supplies and food in Rio de Janeiro-Brazil. Results indicate similar and non-negligible synchronization for different brands, although magnitudes are distant from a perfect synchronization pattern. We find interesting patterns in inter-firm competition, with similar magnitudes across different tire types. Intra-chain synchronization is substantial, indicating that a common price adjustment policy tends to be sustained for each chain across different products.

    In 1983 Hamilton demonstrated the correlation between the price of oil and gross national product for the U.S. economy. A prolific literature followed exploring the potential correlation of oil prices with other important indices like inflation, industrial production, and food prices, using increasingly refined tools. Our work sheds new light on the role of oil prices in shaping the world economy by investigating the metabolic paths of value across trade between 1960 and 2010, by means of Markov Chain analysis. We show that the interdependence of countries' economies are strictly (anti)correlated to the price of oil. We observed a remarkably high correlation of 0.85, unmatched by any former study addressing the correlation between oil price and major economic indicators.

    Full Text Available Micronutrient deficiencies and imbalanced dietary intake tend to occur during the reproductive period among women in China. In accordance with traditional Chinese culture, pregnant women are commonly advised to follow a specific set of dietary precautions. The purpose of this study was to assess dietary intake data and identify risk factors for nutritional inadequacy in pregnant women from urban and rural areas of Deyang region, Sichuan province of China. Cross-sectional sampling was applied in two urban hospitals and five rural clinics (randomly selected in Deyang region. Between July and October 2010, a total of 203 pregnant women in the third trimester, aged 19–42 years, were recruited on the basis of informed consent during antenatal clinic sessions. Semi-structured interviews on background information and 24-h dietary recalls were conducted. On the basis of self-reported height and pre-pregnancy weight, 68.7% of the women had a pre-pregnancy body mass index (BMI within the normal range (18.5 ≤ BMI < 25, 26.3% were found to be underweight with a BMI <18.5 (20.8% in urban vs. 35.6% in rural areas, while only 5.1% were overweight with a BMI ≥30.

    Peak oil is the phenomenon whereby global oil supplies will peak, then decline, with extraction growing increasingly costly. Today's globalized industrial food system depends on oil for fueling farm machinery, producing pesticides, and transporting goods. Biofuels production links oil prices to food prices. We examined food system vulnerability to rising oil prices and the public health consequences. In the short term, high food prices harm food security and equity. Over time, high prices will force the entire food system to adapt. Strong preparation and advance investment may mitigate the extent of dislocation and hunger. Certain social and policy changes could smooth adaptation; public health has an essential role in promoting a proactive, smart, and equitable transition that increases resilience and enables adequate food for all.

    This study was conducted to investigate the association between consumption of processed foods and esophageal cancer risk. A population-based case-control study was designed. For the present study, 254 patients with esophageal squamous cell carcinoma with pathological diagnoses were selected from Yanting during 2008 and 2010 and 254 community-based controls were selected from the same area, individually matched with cases by age and sex. Data on demographic, lifestyle and dietary factors were collected using food frequency questionnaires. A conditional logistic regression model was used to estimate the odds ratio (OR) with adjustments for potential confounders. Compared to the frequency of 3 times/week of preserved vegetables had a significant association with esophageal cancer (OR = 5.01, 95% confidence interval [CI] 2.07, 12.17). In stratified analyses, the OR of increasing intake of preserved vegetables for esophageal cancer were 2.02 in men (95% CI 1.18, 3.48), 3.15 in women (95% CI 1.28, 7.75), 2.41 (95% CI 1.45 4.01) in the persons <65 years old and 1.28 (95% CI 0.35, 4.65) in persons ≥65 years old. Consumption of pickled vegetables was not associated significantly with esophageal cancer risk. Intake of salted meat with a frequency of ≥1 time/week meant that the OR increased to 2.57 (95%CI 1.02, 6.43), but no significant trend or association in subgroup analysis was observed. Preserved vegetable consumption was associated with increased risk of esophageal cancer, while no association was found with pickled vegetables.

    Full Text Available Problem statement: A review of the tourism history shows that tourism as an industry was virtually unknown in Malaysia until the late 1960s. Since then, it has developed and grown into a major industry, making an important contribution to the country's economy. By allocating substantial funds to the promotion of tourism and the provision of the necessary infrastructure, the government has played an important role in the impressive progress of the Malaysian tourism industry. One of the important factors which can attract tourists to Malaysia is the tourism price. Has the price of tourism decreased? To answer this question, it is necessary to obtain the equilibrium prices as well as the yearly trend for Malaysia during the sample period as it will be useful for analysis of the infrastructure situation of the tourism industry in this country. The purpose of the study is to identify equilibrium tourism price trends in Malaysian tourism market. Approach: We use hotel room as representative of tourism market. Quarterly data from 1995-2009 are used and a dynamic model of simultaneous equation is employed. Results: Based on the result during the period of 1995 until 2000, the growth rate of the equilibrium price was greater than consumer price index and producer price index. Conclusion: In the Malaysian tourism market, new infrastructure during this period had not been developed to keep pace with tourist arrivals.

    As increasingly large volumes of sophisticated options (called derivative securities) are traded in world financial markets, determining a fair price for these options has become an important and difficult computational problem. Many valuation codes use the binomial pricing model, in which the stock price is driven by a random walk. In this model, the value of an n-period option on a stock is the expected time-discounted value of the future cash flow on an n-period stock price path. Path-dependent options are particularly difficult to value since the future cash flow depends on the entire stock price path rather than on just the final stock price. Currently such options are approximately priced by Monte carlo methods with error bounds that hold only with high probability and which are reduced by increasing the number of simulation runs. In this paper the authors show that pricing an arbitrary path-dependent option is {number_sign}-P hard. They show that certain types f path-dependent options can be valued exactly in polynomial time. Asian options are path-dependent options that are particularly hard to price, and for these they design deterministic polynomial-time approximate algorithms. They show that the value of a perpetual American put option (which can be computed in constant time) is in many cases a good approximation to the value of an otherwise identical n-period American put option. In contrast to Monte Carlo methods, the algorithms have guaranteed error bounds that are polynormally small (and in some cases exponentially small) in the maturity n. For the error analysis they derive large-deviation results for random walks that may be of independent interest.

    Many companies are now good at managing costs and wringing out manufacturing efficiencies. The TQM movement and the disciplines of Six Sigma have seen to that. But the discipline so often brought to the cost side of the business equation is found far less commonly on the revenue side. The authors describe how a global manufacturer of industrial equipment, which they call Acme Incorporated, recently applied Six Sigma to one major revenue related activity--the price-setting process. It seemed to Acme's executives that pricing closely resembled many manufacturing processes. So, with the help of a Six Sigma black belt from manufacturing, a manager from Acme's pricing division recruited a team to carry out the five Six Sigma steps: Define what constitutes a defect. At Acme, a defect was an item sold at an unauthorized price. Gather data and prepare it for analysis. That involved mapping out the existing pricing-agreement process. Analyze the data. The team identified the ways in which people failed to carry out or assert effective control at each stage. Recommend modifications to the existing process. The team sought to decrease the number of unapproved prices without creating an onerous approval apparatus. Create controls. This step enabled Acme to sustain and extend the improvements in its pricing procedures. As a result of the changes, Acme earned dollar 6 million in additional revenue on one product line alone in the six months following implementation--money that went straight to the bottom line. At the same time, the company removed much of the organizational friction that had long bedeviled its pricing process. Other companies can benefit from Acme's experience as they look for ways to exercise price control without alienating customers.

  11. The price level and monetary policy

    Charles P. Kindleberger

    2002-03-01

    Full Text Available Most central banks are required to or choose to stabilize a price index, largely by manipulating short term interest rates. A serious problem is which index to choose among the national income deflator, wholesale prices, the cost of living, with or eliminating highly volatile commodities such as food and energy, to produce a core index, plus others such as housing, including or without imputed rent of owner-occupied houses, or assets, whether equities or houses. No obvious and widely agreed index exists. Even if there were a clear choice, there remains a question whether a central bank should carefully consider action in order to achieve other goals: full employment, adjustment of the balance of payments, of the exchange rate, prevention of bubbles in asset prices, or recovery from financial crises. If so, the question of central bank weapons remains: monetary expansion or contraction, credit controls, for overall or for particular purposes, and moral suasion.

    Promotion of healthy eating is an effective public health strategy to prevent chronic disease incidence and progression. However, food prices can impede healthy eating, especially in rural communities. The purpose of this study was to determine whether food costs are associated with nutritional quality, geographic location, and month of year. The Overall Nutritional Quality Index and cost of 92 foods were assessed four times over a 10-month period in the primary grocery stores in four Kentucky counties, two rural and two urban. Repeated measures analysis of variance was used to assess differences in food costs by nutritional quality, county, and month. Among more nutritious food items, costs were lower in urban areas. This was particularly true among foods in the highest quartile of nutritional quality. Across all counties, there was a pattern of highest per-serving costs in the second quartile of nutritional quality, whereas more nutritious foods were less expensive. Strategies that help individuals improve the ability to identify and prepare less costly foods with high nutritional value may be effective in improving dietary habits, particularly in rural, impoverished food deserts.

    Trophic transfer of polybrominated diphenyl ethers (PBDEs) in aquatic ecosystems is an important criterion for assessing their environmental risk. This study analyzed 13 PBDEs in marine organisms collected from coastal area of Bohai Bay, China. The concentrations of total PBDEs (Σ13PBDEs) ranged from 12 ± 1.1 ng/g wet weight (ww) to 230 ± 54 ng/g ww depending on species. BDE-47 was the predominant compound, with a mean abundance of 20.21 ± 12.97% of total PBDEs. Stable isotopic ratios of carbon (δ(13)C) and nitrogen (δ(15)N) were analyzed to determine the food web structure and trophic level respectively. Trophic magnification factors (TMFs) of PBDEs were assessed as the slope of lipid equivalent concentrations regressed against trophic levels. Significant positive relationships were found for Σ13PBDEs and eight PBDE congeners (BDE-28, BDE-47, BDE-49, BDE-66, BDE-85, BDE-99, BDE-100 and BDE-154). Monte-Carlo simulations showed that the probabilities of TMF >1 were 100% for Σ13PBDEs, BDE-47, BDE-85, BDE-99 and BDE-100, 99% for DE-28, BDE-49, BDE-66 and BDE-154, 94% for BDE-153, and 35% for BDE-17.

  3. Trends in prices to commercial energy consumers in the competitive Texas electricity market

    To date, the price of electricity to commercial or business energy consumers has generally increased at greater rates in the areas of Texas where retail competition has been introduced than in areas that do not enjoy competition. Trends in commercial competitive prices have largely mirrored trends in residential prices. Market restructuring has tended to increase the sensitivity of retail electricity prices to changes in the price of natural gas, the marginal fuel used for generation in Texas. Consequently, the rapid increases in the commodity price of natural gas following restructuring led to increases in competitive electric rates which exceeded the increases in areas not exposed to restructuring, where the fuel component of electric rates tend to reflect a weighted average of the utilities' fuel costs. There is some evidence that pricing behavior by competitive retailers changed when the retailers affiliated with the incumbent utilities were permitted some pricing flexibility, resulting in a reduction in prices.

  4. DEMAND AND PRICES

    2014-08-01

    Full Text Available Studying the consumer’s behavior by the ordinal approach of utility with the help of indifference curves allows us to deduce the two “movement laws of demand” in this chapter: the demand for a “normal” good is decreasing function of its price and an increasing function of income. We will use the elasticity concept to measure the intensity of the relation that is established between the demand, on the one hand, and prices or income, on the other hand: elasticity – price, direct and crossed, and elasticity – income. We can classify the goods in many categories, depending on the values that this elasticity takes. The demand elasticity can be determined depending on price and income. It reflects the proportion in which the demand for different products changes with the modification of the consumers’ income, the other factors remaining constant. The elasticity compared to the income is a demonstration of legality from the consumer’s sphere, which determines a certain hierarchy of the needs of each population category in a certain level of income. The movement of prices orients both the options and decisions of producers, namely the most useful productions and the most efficient investments, as well as the consumers’ options and decisions on the most advantageous buying of goods and services that they need. The prices appear as a “signal system” coordinating and making coherence the economic agents’ decisions – producers, consumers and population.

  7. Food inflation in South Africa: some implications for economic policy.

    2011-01-01

    This paper analyses the trends in food price movements in South Africa between 1980 and 2008. There are three main results emanating from the analysis in this paper. Firstly, food price movements have played a large role in generating inflationary episodes in South Africa. Secondly, while external influences do matter, South African food price movements are mainly due to domestic influences. This implies that national policy has an important role to play in taming domestic food price inflation. Thirdly, given the strong second round impacts, food price movements warrant special attention in monetary policymaking. Core measures of inflation that exclude food price movements may not accurately reflect the underlying inflationary pressures in the economy and could compromise the attainment of the goal of price stability.

    Objectives. We examined whether physical proximity to supermarkets or supermarket price was more strongly associated with obesity risk. Methods. The Seattle Obesity Study (SOS) collected and geocoded data on home addresses and food shopping destinations for a representative sample of adult residents of King County, Washington. Supermarkets were stratified into 3 price levels based on average cost of the market basket. Sociodemographic and health data were obtained from a telephone survey. Modified Poisson regression was used to test the associations between obesity and supermarket variables. Results. Only 1 in 7 respondents reported shopping at the nearest supermarket. The risk of obesity was not associated with street network distances between home and the nearest supermarket or the supermarket that SOS participants reported as their primary food source. The type of supermarket, by price, was found to be inversely and significantly associated with obesity rates, even after adjusting for individual-level sociodemographic and lifestyle variables, and proximity measures (adjusted relative risk = 0.34; 95% confidence interval = 0.19, 0.63) Conclusions. Improving physical access to supermarkets may be one strategy to deal with the obesity epidemic; improving economic access to healthy foods is another. PMID:22698052

    Full Text Available Twelve people became ill with vomiting and diarrhoea approximately four hours after eating cake with a cream filling at a birthday party and on the day following. The cake had been prepared by a food handler who had long experience in preparing foods for such functions. Staphylococcus aureus that produced enterotoxin A was isolated from the nose, the fingernails, and a healed infection on the neck of the food handler, and from the cake. Enterotoxin A was detected in the remaining portion of the cake. The cake, while still warm, had been refrigerated for one hour after it was prepared before it was removed for the party; it was refrigerated after the party. The cake was large (6 kg and hence it was not adequately cooled in the hour during wich it was refrigerated before the party. The conclusion is that the cake was accidentally contaminated by the food handler and inadequately cooled before it was eaten.

Variance swaps are similar instruments on future realized variance, the square of future realized volatility. Unlike a plain vanilla option, whose volatility exposure is contaminated by its asset price dependence, volatility and variance swaps provide a pure exposure to volatility alone.

  14. IS THE PRICE RIGHT? PRICING FOR LONG TERM PROFITABILITY

    Directory of Open Access Journals (Sweden)

    Andrea Erika NYÁRÁDI

    2007-01-01

    Full Text Available The way how we choose our pricing strategy has a significant impact on company’s success. Nowadays companies more and more adopt a new way of thinking in pricing, namely pricing for a long term period in order to bring higher profitability, to build an efficient pricing strategy. Marketers have only recently begun to focus seriously on effective pricing. These companies are the so called progressive companies. They have begun doing more than just worrying about pricing. To increase profitability many are abandoning traditional reactive pricing procedures in favor of proactive pricing, making explicit corporate decisions to change their focus to growth in top-line sales to growth in profitability. The long-term implications of price strategies are still under-researched, and managers should be aware of shifts in customer reactions that may result from frequent adoption of certain strategies. The company pricing strategy should be seen in relation to developments in the company variables, internal ones (capital strength, competencies, organizational conditions, efficiency of the work force etc. as well as external ones (customers, competitors, the technological development etc., adopting strategic pricing. In this paper I will present the most effective pricing strategies leading to long term profitability, and also suggest practical conditions for pricing strategies to maximize profit in the long run.

  15. Food web structure of the coastal area adjacent to the Tagus estuary revealed by stable isotope analysis

    Vinagre, C.; Máguas, C.; Cabral, H. N.; Costa, M. J.

    2012-01-01

    The identification of energy sources, pathways and trophic linkages among organisms is crucial for the understanding of food web dynamics. Stable isotopes were used to identify the trophic level of food web components and track the incorporation of organic matter of different origins in the coastal ecosystem adjacent to the Tagus estuary. It was shown that the river Tagus is a major source of organic carbon to this system. Also, the wide difference in δ 13C among the primary consumers allowed the identification of the pelagic and the benthic energy pathways. The maximum trophic level observed was 2.4 for Sepia officinalis. This value is indicative of a short food web. It was concluded that the diet of the upper trophic level species relies directly on the lower food web levels to a considerable extent, instead of relying mostly on intermediate trophic level species. Moreover, the δ 15N values of primary consumers were very close to that of particulate organic matter, probably due to poorly known processes occurring at the basis of the food web. This lowers the trophic length of the whole food web. Reliance on benthic affinity prey was high for all upper trophic level secondary consumers.

    Understanding how genetics influences obesity, brain activity and eating behaviour will add important insight for developing strategies for weight-loss treatment, as obesity may stem from different causes and as individual feeding behaviour may depend on genetic differences. To this end, we examined how an obesity risk allele for the FTO gene affects brain activity in response to food images of different caloric content via functional magnetic resonance imaging (fMRI). Thirty participants homozygous for the rs9939609 single nucleotide polymorphism were shown images of low- or high-calorie food while brain activity was measured via fMRI. In a whole-brain analysis, we found that people with the FTO risk allele genotype (AA) had increased activity compared with the non-risk (TT) genotype in the posterior cingulate, cuneus, precuneus and putamen. Moreover, higher body mass index in the AA genotype was associated with reduced activity to food images in areas important for emotion (cingulate cortex), but also in areas important for impulse control (frontal gyri and lentiform nucleus). Lastly, we corroborate our findings with behavioural scales for the behavioural inhibition and activation systems. Our results suggest that the two genotypes are associated with differential neural processing of food images, which may influence weight status through diminished impulse control and reward processing.

    Multi-sector sticky price models have surprising implications when durable goods have flexible prices. While in actual data the production of virtually all durables exhibits strong negative responses to monetary contractions, in dynamic general equilibrium models a monetary contraction causes the output of flexibly priced durables to expand. Indeed, in the polar case in which only nondurables have sticky prices, the negative comovement of durable and nondurable production exactly offsets and ...

    1993-11-01

    From the analysis of experimental data on radioactive contamination of various fish, it is suggested that predatory fish specimens can be used as bioindicators of radionuclide accumulation in reservoir food chains of the Chernobyl emergency area. The increased content of cesium radionuclides were detected in the muscle tissue of predatory fish collected in various regions of the Chernobyl emergency area. In most of the water bodies studied, maximum contamination levels of predatory fish by radionuclides of cesium occurred in 1987-1988, whereas in 'nonpredatory' fish the concentration of cesium was maximum, as a rule, in the first year following the accident. The exposure doses of fish of various ecological groups and ages are estimated. The exposure doses of various population groups, using fish from contaminated water bodies, are also estimated. When forming the environmental data bank for the Chernobyl accident zone it is suggested that perch, pike-perch and pike be used as bioindicators of radioactive contamination of food chains.

    2012-01-01

    Recent droughts in the midwestern United States threaten to cause global catastrophe driven by a speculator amplified food price bubble. Here we show the effect of speculators on food prices using a validated quantitative model that accurately describes historical food prices. During the last six years, high and fluctuating food prices have lead to widespread hunger and social unrest. While a relative dip in food prices occurred during the spring of 2012, a massive drought in the American Midwest in June and July threatens to trigger another crisis. In a previous paper, we constructed a model that quantitatively agreed with food prices and demonstrated that, while the behavior could not be explained by supply and demand economics, it could be parsimoniously and accurately described by a model which included both the conversion of corn into ethanol and speculator trend following. An update to the original paper in February 2012 demonstrated that the model previously published was predictive of the ongoing pric...

    2004-01-01

    The cross-fertilization between artificial intelligence and computational finance has resulted in some of the most active research areas in financial engineering. One direction is the application of machine learning techniques to pricing financial products, which is certainly one of the most complex issues in finance. In the literature, when the interest rate,the mean rate of return and the volatility of the underlying asset follow general stochastic processes, the exact solution is usually not available. In this paper, we shall illustrate how genetic algorithms (GAs), as a numerical approach, can be potentially helpful in dealing with pricing. In particular, we test the performance of basic genetic algorithms by using it to the determination of prices of Asian options, whose exact solutions is known from Black-Scholesoption pricing theory. The solutions found by basic genetic algorithms are compared with the exact solution, and the performance of GAs is ewluated accordingly. Based on these ewluations, some limitations of GAs in option pricing are examined and possible extensions to future works are also proposed.

    Healthcare providers can learn a variety of pricing lessons from the retail market: For providers, wholesale pricing--"the price to play"--alone is not enough. Once a hospital or health system chooses a market position, the provider creates an expectation that must be met-consistently. Consumer loyalty is fluid, and the price of care or service is not always the motivator for choosing one organization over another; intangibles such as location and level of customer service also drive purchasing decisions.

    Ensuring food security requires food production and distribution systems function throughout disruptions. Understanding the factors that contribute to the global food system’s ability to respond and adapt to such disruptions (i.e. resilience) is critical for understanding the long-term sustainability of human populations. Variable impacts of production shocks on food supply between countries indicate a need for national-scale resilience indicators that can provide global comparisons. However, methods for tracking changes in resilience have had limited application to food systems. We developed an indicator-based analysis of food systems resilience for the years 1992–2011. Our approach is based on three dimensions of resilience: socio-economic access to food in terms of income of the poorest quintile relative to food prices, biophysical capacity to intensify or extensify food production, and the magnitude and diversity of current domestic food production. The socio-economic indicator has a large variability, but with low values concentrated in Africa and Asia. The biophysical capacity indicator is highest in Africa and Eastern Europe, in part because of a high potential for extensification of cropland and for yield gap closure in cultivated areas. However, the biophysical capacity indicator has declined globally in recent years. The production diversity indicator has increased slightly, with a relatively even geographic distribution. Few countries had exclusively high or low values for all indicators. Collectively, these results are the basis for global comparisons of resilience between countries, and provide necessary context for developing generalizations about resilience in the global food system.

  2. Water pricing towards sustainability of water resources: A case study in Beijing

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    The role of water pricing for managing water resources iswidely recognized in many areas of the world because of theincreasing scarcity of water resources, a high competition betweenwater uses and environmental degradation. Based on the analysis ofcost of water, this paper explores which types of cost should bereflected in the water pricing enhancing the sustainability ofwater resources. The principle of full cost pricing in which thecost should include supply cost, opportunity cost and externalitiesis proposed as a means to achieve the sustainability of waterresources. In a case study of Beijing, low water price is analyzedas one reason for unsustainable water consumption. Thus waterpricing justified is necessary and pressing. It is proposed tojustify water price in phased manner and eventually towards fullcost pricing. The assessment of impacts on water resources byraising water price shows water pricing could alleviate the conflict between water supply and demand. This paper concludes thatwater pricing can play an effective role in enhancing thesustainability of water resources in Beijing.

  13. Draft regulatory analysis: Notice of proposed rulemaking for the allocation and pricing of gasohol

    Energy Technology Data Exchange (ETDEWEB)

    None,

    1980-05-01

    The three principal problem areas addressed are: how to price unleaded blend stock and gasohol; how blenders are to obtain unleaded blend stock to blend with ethanol to produce gasohol; and how gasohol suppliers may distribute gasohol to purchasers. The proposed pricing and allocation rules, if adopted as final rules, would be in effect for about a year, because the statutory authority for gasoline price and allocation controls has an expiration date of September 30, 1981. The principal issues addressed are: what volume of ethanol and gasohol production can be expected between now and the end of 1981; what prices these products are likely to reach, independent of the rule and its alternative; what effect the rule and its alternative may have on the price and distribution of ethanol and gasohol; and what effect the rule and its alternative may have on motor vehicle misfueling and competition in the motor gasoline industry. On supply issues, it is concluded that by December, 1981, ethanol and gasohol production should increase by a factor of 3 or 4 above present levels, enough to meet the President's goals, without requiring additional corn acreage or adversely affecting food production. Ethanol production should increase from its present level of about 92 million gallons per year (6062 B/D) to the 3, 4, and 7 hundred million gallons per year levels (20,000, 30,000, and 45,000 B/D) necessaryto produce gasohol at year-end rates of 200,000 B/D in 1980, 300,000 B/D in 1981 and 450,000 B/D in 1982. In 1980 gasohol will represent about 3.2 percent of the total gasoline market, and 7.9 percent of the total unleaded market. Gasohol should help extend, rather than adversely affect, unleaded supplies. 30 references, 8 tables.

    Wanshan mercury mine is the largest mercury deposit in Guizhou Province of China, but there were few reports on mercury toxic effect in the mining area. In order to study the neurotoxicity of food from Wanshan mercury mine area and probe into the effect of food from Wanshan mercury miner area on the changes of brain oxidative damage and expression of c-fos gene. The rats were exposed to mercury contaminated food for 20 d. The content of malondialdehyde (MDA), superoxide dismutase (SOD),GSH-peroxidase (GSH-px) and Glutathione (GSH) in rat brain was measured, and the effect of mercury contaminated rice on the expression of c-fos mRNA in rat brain and the expression of c-FOS protein in cortex, hippocampus were observed using reverse transcription polymerase chain reaction (RT-PCR) and immunocytochemical methods. The results showed the levels of GSH, MDA,SOD and of GSH-dependent enzymes in the rat brain changed between exposure groups and control group; The mercury polluted rice induced significantly the expression of c-fos mRNA; the c-FOS positive cells in hippocampus and cortex of exposure groups were significant different from control group (P<0.01). It could be concluded that oxidative stress signals could contribute to the induction of immediate early genes (IEGs); free radicals and their by-products might not only cause oxidative damage, but also influenced gene expression; IEGs c-fos participated in the toxicity process of brain injury by mercury polluted food.

    There has been surprisingly little research to date on the supply-side role of food manufacturers on equilibrium health outcomes for consumers. In this letter we consider an oligopoly model in which food processors choose the health composition of manufactured food. We show that price competition between food processors leads to unhealthy food composition in the market equilibrium, even under circumstances in which consumers know food composition is unhealthy. Taxes on manufactured food decrease the healthiness of manufactured foods whenever improved consumer health increases the price elasticity of food demand. Copyright © 2016 John Wiley & Sons, Ltd.

    In this paper we derive a space-time model for electricity spot prices. A general spatial Durbin model that incorporates the temporal as well as spatial lags of spot prices is presented. Joint modeling of space-time effects is necessarily important when prices and loads are determined in a network...... of power exchange areas. We use data from the Nord Pool electricity power exchange area bidding markets. Different spatial weight matrices are considered to capture the structure of the spatial dependence process across different bidding markets and statistical tests show significant spatial dependence...

    Full Text Available The real estate market is complex and influenced by too many factors. Real Estate market in Albania has experienced a boom after the 1990. We have inherited from the communist system a very poor market of housing. The number of dwellings in 1990 in Albania was 219 dwellings per 1000 inhabitants and the useful floor space was 5 m² per person, but in Bulgaria number of dwellings per 1,000 people varies 465 and in Romania average useful floor space per person was 37 sq. The data used in this study are derived from the database of the World Bank, the Institute of Statistics, reports of Bank of Albania also from information provided individually on the ground and different sources. In this study is analyzed the relationship that exists between economic growth, remittances and the price of dwellings in Albania. The dependent variable is the average price of housing in major cities of Albania. Independent variables in the model are GDP per capita and the remittances. The Econometric model is a Linear Regress equation and the period are the years from 1998 to 2013. The model used is the statistical program EViews 6.0. Unfortunately the information let the desired, so we do not have an official detailed information on prices of Albanian real estate market. In Albania few researchers have been studying real estate market in Albania.
