  1. Limitations of Certification and Supply Chain Standards for Environmental Protection in Commodity Crop Production

    OpenAIRE

    Kurt B. Waldman; John M. Kerr

    2014-01-01

    Motivated by recent increases in water pollution in major US agricultural watersheds and by the shortcomings of government programs to control non–point source pollution, this paper examines the prospects for using product certification (ecolabeling) and business-to-business supply chain standards for environmental protection in commodity crop production. We introduce the sources of demand for certification and supply chain standards and the political and economic context in which they have e...

  2. From Public to Private Standards for Tropical Commodities: A Century of Global Discourse on Land Governance on the Forest Frontier

    Directory of Open Access Journals (Sweden)

    Derek Byerlee

    2015-04-01

    Full Text Available Globalization and commodity exports have a long history in affecting land use changes and land rights on the tropical forest frontier. This paper reviews a century of social and environmental discourse around land issues for four commodities grown in the humid tropics—rubber, cocoa, oil palm and bananas. States have exercised sovereign rights over land and forest resources and the outcomes for deforestation and land rights of existing users have been quite varied depending on local institutional contexts and political economy. In the current period of globalization, as land use changes associated with tropical commodities have accelerated, land issues are now at center stage in the global discourse. However, efforts to protect forests and the rights of local communities and indigenous groups continue to be ad hoc and codification of minimum standards and their implementation remains a work in progress. Given a widespread failure of state directed policies and institutions to curb deforestation and protect land rights, the private sector, with the exception of the rubber industry, is emphasizing voluntary standards to certify sustainability of their products. This is an important step but expectations that they will effectively address concerns about the impact of tropical commodities expansion might be too high, given their voluntary nature, demand constraints, and the challenge of including smallholders. It is also doubtful that private standards can more than partially compensate for long standing weaknesses in land governance and institutions on the forest frontier.

    2008-01-01

    To explain the value added along the coffee commodity chain we propose and estimate a theoretical model of the coffee commodity chain. The theoretical model consists of four markets and five agents in the coffee commodity chain and predicts that prices in the coffee commodity chain move together but are also influenced by income, technology and production. A vector error correction model is used to test the theoretical predictions. In addition to the theoretical conclusions the empirical mode...

  9. Strategic pricing of commodities

    OpenAIRE

    Jörnsten, Kurt; Ubøe, Jan

    2006-01-01

    In this paper we will consider a setting where a large number of agents are trading commodity bundles. Assuming that agents of the same type have a certain utility attached to each transaction, we construct a statistical equilibrium which in turn implies prices on the different commodities. Our basic question is then the following: Assume that some commodities come out with prices that are socially unacceptable. Is it possible to change these prices systematically if a new type of agents is p...

  10. Commodities Inventory Effect

    OpenAIRE

    Carpantier, Jean-Francois; DUFAYS, Arnaud

    2013-01-01

    Does commodity price volatility increase when inventories are low? We are the first ones to document this relationship. To that aim, we estimate asym- metric volatility models for a large set of commodities over 1994-2011. Since inventories are hard to measure, especially for high frequency data, we use positive return shocks as a new original proxy for inventories and find that asymmetric GARCH models reveal a significant inventory effect for many commodities. The results look robust. They h...

  13. Financialization of commodities

    Directory of Open Access Journals (Sweden)

    Michał Falkowski

    2011-12-01

    Full Text Available The basic theory of price formation tells us how the price of a particular asset will change based on the adjustment to its supply and demand. However, values of assets are also determined by other business fundamentals, company’s and world events, human psychology, and investors’ belief about the possible future profit. In recent history that lead to an increase of individual and institutional investors’ interest in allocating their resources in commodity markets. With a large inflow of capital commodities’ prices started to rise making them attractive components to effective investment portfolios. The presented paper addresses the issue of so called commodities ‘financialization’ process. It looks at the main factors standing behind commodities’ price movements and to what extent financial market participants contributed to commodities price volatility in recent years. Based on the data examined it distinguishes the involvement of both commercial and non-commercial traders in short and long term periods of time. As well as explaining the impact of growing investors’ interest in commodity markets it defines other market forces - like currency appreciations and emerging markets - as being part of increased volatility in raw and soft commodity markets. Along with market examination the paper focuses on possible future outcomes in attempts to regulate commodities derivatives markets and potential effects of those efforts.

    This paper argues that transparency-boosting measures specifically tailored to commodity and commodity derivatives markets are much needed. In particular, encouraging the creation of a clearing infrastructure for OTC commodity and commodity derivatives markets would be desirable. Moreover, EU regulators should consider setting up a new, more effective market abuse regime aimed at preventing manipulation in both the physical and financial commodities markets. Finally, in cooperation with the G...

  15. UNCTAD commodity yearbook 1990

    International Nuclear Information System (INIS)

    The Commodity Yearbook is intended to provide disaggregated data at the world, regional and country levels for trade and consumption in selected agricultural primary commodities and minerals, ores and metals. Production series have been included for the latter group of commodities, since comprehensive diaggregated data are unavailable elsewhere. Basic tables have been designed, from both the commodity and the country point of view, to serve as background material to international commodity discussions and negotiations in the United Nations Conference on Trade and Development. The classification of countries and territories by region has been adopted for statistical convenience only, and follows that employed by the Statistical Office of the United Nations. Four main regions are defined: Developed market economy countries, Countries of Eastern Europe, Socialist countries of Asia and Developing countries and territories. For developed and developing countries and territories, the main regions have been further subdivided (e.g., EEC, EFTA, Africa, etc.) to provide additional information. The exact composition of each region is shown in section V of the general notes

  16. Cross-commodity hedges

    International Nuclear Information System (INIS)

    Energy risk management is the principal topic of this paper. Four major subjects are examined: cross-commodity trading objectives (reduce the risk of an underlying exposure in another commodity); portfolio risk reduction (an Alberta power distributor exposed to high pool prices could protect against high pool prices through a fixed price purchase of Alberta natural gas); tailoring pricing to customer needs (sell power to the gas producer indexed to the price of gas); and (4) reducing insurance costs (rather than purchasing downside protection (puts) individually against oil and gas prices, a producer could purchase a basket option). Since the key issue in cross-commodity transactions is the estimation of correlation, it is important to be prepared to alter correlation assumptions. 1 tab., 2 figs

  18. CHAOS IN ECONOMY (COMMODITIES

    Directory of Open Access Journals (Sweden)

    A. Bonatto

    2015-06-01

    Full Text Available Chaos is based on nonlinear phenomena occurring everywhere, but it brings stability and its own structure. Many are the linear realities, but there are phenomena to which mathematical systems do not describe acceptably. Charting these relationships is challenging to obtain a representative model of reality. In the chaos, a small disturbance will amplify, and initially close trajectories diverge. The instability leads to new aspects. This helps in the process of modeling for the study of simulations that are applied in the financial and economic fields, showing that the market continues to disorder in an organized manner. Research in the last 25 years focus on the risk and volatility of the behavior of commodity prices. The analysis and forecast of price behavior in commodity markets are relevant both for producers, cooperatives and industries and for global financial markets. These applications aim to enable projections of future commodity prices, improving decision-making in the future. In modeling commodity time series we must take into account several factors such as seasonality in prices due to fluctuations in supply and demand during periods of crop and season. The analysis of the behavior of prices of an asset is important for predicting future revenue, past behavior analysis of a series of prices and study of the historical price of a product. That's one reason the applicability of chaos theory: the ability to identify and explain fluctuations in the markets that appear to be random, but actually are not.

  19. Mineral Commodity Summaries 2008

    U.S. Geological Survey

    2008-01-01

    Each chapter of the 2008 edition of the U.S. Geological Survey (USGS) Mineral Commodity Summaries (MCS) includes information on events, trends, and issues for each mineral commodity as well as discussions and tabular presentations on domestic industry structure, Government programs, tariffs, 5-year salient statistics, and world production and resources. The MCS is the earliest comprehensive source of 2007 mineral production data for the world. More than 90 individual minerals and materials are covered by two-page synopses. National reserves and reserve base information for most mineral commodities found in this report, including those for the United States, are derived from a variety of sources. The ideal source of such information would be comprehensive evaluations that apply the same criteria to deposits in different geographic areas and report the results by country. In the absence of such evaluations, national reserves and reserve base estimates compiled by countries for selected mineral commodities are a primary source of national reserves and reserve base information. Lacking national assessment information by governments, sources such as academic articles, company reports, common business practice, presentations by company representatives, and trade journal articles, or a combination of these, serve as the basis for national reserves and reserve base information reported in the mineral commodity sections of this publication. A national estimate may be assembled from the following: historically reported reserves and reserve base information carried for years without alteration because no new information is available; historically reported reserves and reserve base reduced by the amount of historical production; and company reported reserves. International minerals availability studies conducted by the U.S. Bureau of Mines, before 1996, and estimates of identified resources by an international collaborative effort (the International Strategic Minerals

  3. Commodity-Free Calibration

    Science.gov (United States)

    2008-01-01

    Commodity-free calibration is a reaction rate calibration technique that does not require the addition of any commodities. This technique is a specific form of the reaction rate technique, where all of the necessary reactants, other than the sample being analyzed, are either inherent in the analyzing system or specifically added or provided to the system for a reason other than calibration. After introduction, the component of interest is exposed to other reactants or flow paths already present in the system. The instrument detector records one of the following to determine the rate of reaction: the increase in the response of the reaction product, a decrease in the signal of the analyte response, or a decrease in the signal from the inherent reactant. With this data, the initial concentration of the analyte is calculated. This type of system can analyze and calibrate simultaneously, reduce the risk of false positives and exposure to toxic vapors, and improve accuracy. Moreover, having an excess of the reactant already present in the system eliminates the need to add commodities, which further reduces cost, logistic problems, and potential contamination. Also, the calculations involved can be simplified by comparison to those of the reaction rate technique. We conducted tests with hypergols as an initial investigation into the feasiblility of the technique.

  5. Outlook '98 - Commodity markets

    International Nuclear Information System (INIS)

    Canadian oil and natural gas producers'' participation in commodity and foreign exchange markets to alter the pricing characteristics of their commodity portfolios was reviewed. It was concluded that through the various risk management structures available from financial and physical market participants, Canadian oil and gas producers retain the ongoing ability to design, pro-actively, their desired exposure to oil and gas prices. Various industry-wide re-examination of risk management programs have taken place during the past two years. Based on these studies, the industry anticipates material volatility in West Texas Intermediate (WTI) oil and Alberta natural gas prices throughout 1998. Furthermore, there is considerable uncertainty surrounding the price differentials between WTI crude and Canadian oil streams, and between Alberta gas prices and other North American regional gas markets. Against this background of uncertainty, it is reasonable to predict that companies will use risk management strategies in an effort to outperform industry average prices, thereby ensuring that pro-active risk management activity will continue throughout 1998

  7. Negotiating commodity price risk

    International Nuclear Information System (INIS)

    A review of the negotiations that led to PrimeWest's acquisition of Northstar's Grand Forks property at the end of 1997 was presented as an example of dealing with commodity price risk in an asset purchase. The paper described the pricing environment at the time of negotiations, the oil price collar, and the closing results. In 1998 PrimeWest drilled nine out of ten successful wells which are currently producing at an average production rate of 2776 bpd. In the event, PrimeWest has been able to maintain good value in its Grand Forks property acquisition, despite low oil prices. It is believed that the oil price collar was the main component of value retention. The oil price collar was the mechanism to protect PrimeWest, should oil prices remain below the field price. It is believed that this transaction would not have occurred without the price collar. 5 tabs., 12 figs

  19. Incorporating Agroforestry Approaches into Commodity Value Chains

    Science.gov (United States)

    Millard, Edward

    2011-08-01

    The productivity of tropical agricultural commodities is affected by the health of the ecosystem. Shade tolerant crops such as coffee and cocoa benefit from environmental services provided by forested landscapes, enabling landscape design that meets biodiversity conservation and economic needs. What can motivate farmers to apply and maintain such landscape approaches? Rather than rely on a proliferation of externally funded projects new opportunities are emerging through the international market that buys these commodities. As part of their growing commitment to sustainable supply chains, major companies are supporting agroforestry approaches and requiring producers and traders to demonstrate that the source of their commodities complies with a set of principles that conserves forested landscapes and improves local livelihoods. The paper presents examples of international companies that are moving in this direction, analyzes why and how they are doing it and discusses the impact that has been measured in coffee and cocoa communities in Latin America and Africa. It particularly considers the role of standards and certification systems as a driver of this commitment to promote profitable operations, environmental conservation and social responsibility throughout the coffee and cocoa value chains. Such approaches are already being taken to scale and are no longer operating only in small niches of the market but the paper also considers the limitations to growth in this market-based approach.

  6. "Pricing Average Options on Commodities"

    OpenAIRE

    2010-01-01

    This paper proposes a new approximation formula for pricing average options on commodities under a stochastic volatility environment. In particular, it derives an option pricing formula under Heston and an extended lambda-SABR stochastic volatility models (which includes an extended SABR model as a special case). Moreover, numerical examples support the accuracy of the proposed average option pricing formula.

  8. A study on the systematization of commodity classification

    International Nuclear Information System (INIS)

    International community is trying to prevent the spread of WMD (Weapons of Mass Destruction), especially nuclear weapons. These efforts result in the declaration of UNSC Resolution 1540 in 2004, which made export controls the international norms for all nations in the world. Korea enacted Foreign Trade Act in 1989 to adhere to the export control standards worldwide. Export control system in Korea consists of commodity classification system and export license system. The commodity classification system is used to identify strategic commodity. The Export License system is used to verify that exports have met the conditions required by the international export control system. NSG guidelines, the NSG handbook and Public Notice on Trade of Strategic Items are used to classify items and technology However, some items or technology in NSG guidelines should be especially designed or prepared (EDP). It is difficult to determine which items or technology is strategic commodity because EDP criteria are qualitative. NSG or participant states don't provide clear criteria to classify items and technology but recommend establishing standards autonomously. Hence the result of deliberation on the same items and technology may be different by reviewer's experience, knowledge and governmental policy. It causes confusion of reviewers and export companies In this research, commodity classification systematization by EDP criteria's clarification was performed to increase consistency and efficiency

  9. Is women's labor a commodity?

    Science.gov (United States)

    Anderson, Elizabeth S

    1990-01-01

    ...A commercial surrogate mother is anyone who is paid money to bear a child for other people and terminate her parental rights, so that the others may raise the child as exclusively their own. The growth of commercial surrogacy has raised with new urgency a class of concerns regarding the proper scope of the market. Some critics have objected to commercial surrogacy on the ground that it improperly treats children and women's reproductive capacities as commodities. The prospect of reducing children to consumer durables and women to baby factories surely inspires revulsion. But are there good reasons behind the revulsion? And is this an accurate description of what commercial surrogacy implies? This article offers a theory about what things are properly regarded as commodities which supports the claim that commercial surrogacy constitutes an unconscionable commodification of children and of women's reproductive capacities.

    2006-01-01

    "Town" and commodity circulation are two closely interrelated concepts.A town is born through the exchange of commodities;it is formed by an increase in trade efficiency.The trade efficiency caused by the density of economy is the standard of rationalization of the town scale.The development of a town promotes the development from simple commodity circulation to developed commodity circulation,while the difference in the level of urbanization is an important reason for differences in the circulation level.Therefore,the strategy of being guided by circulation will be a basic way to push forward urbanization healthily in China.

    Full Text Available Problem statement: Commodity Flow Survey (CFS was launched to collect comprehensive freight flow data throughout the kingdom of Thailand. The survey’s database is the most complete collection of commodity flow data in Thailand. The need to reveal interregional freight characteristics using available data from the CFS led to the objectives of this research. Approach: An origin destination matrix based on province was calibrated using a flexible Box-Cox function form. It used maximum likelihood and the backward method for calibration and Root Mean Square Error (RMSE and Mean Relative Error (MRE to verify the model’s performance. Independent variables were classified into three groups: origin variable, destination variable and geographic variable. The origin variable represented the behavior of the trip as generated at the place of origin. Some consumption occurred at the origin. The employment and the average plant size variables were selected for potential productivity while personal income per capita and total populations were included to explain consumption behavior at the origin. Personal income per capita and total populations were selected for destination variables which act as proxy for final demand at the destination. The third category, distance, was the most conventional friction variable for geographical variables. Results: The calibrated model revealed that origin income, origin average plant size and origin population performed poorly. Therefore these variables were eliminated. The best developed model included four strongly significant variables at a 5% level: origin employment, destination population, destination income per capita and distance. Conclusion: The results showed that the selected variables and the Box-Cox functional form were successful in explaining behavior of interregional freight transportation in Thailand. The developed model was the first interregional freight transportation model to be

    We have implemented a parallel computer architecture based entirely upon commodity personal computer components. Using 16 Intel Pentium Pro microprocessors and switched fast ethernet as a communication fabric, we have obtained sustained performance on scientific applications in excess of one Gigaflop. During one production astrophysics treecode simulation, we performed 1.2 x 10{sup 15} floating point operations (1.2 Petaflops) over a three week period, with one phase of that simulation running continuously for two weeks without interruption. We report on a variety of disk, memory and network benchmarks. We also present results from the NAS parallel benchmark suite, which indicate that this architecture is competitive with current commercial architectures. In addition, we describe some software written to support efficient message passing, as well as a Linux device driver interface to the Pentium hardware performance monitoring registers.

It considers the conceptual and political implications of thinking of essential oils as, in turn, commodities, materials and essences. I argue that both cultural studies and aromatherapy have something to learn from each other. Classic materialist approaches might do well to focus more attention on the material properties and effects of things. Aromatherapy, on the other hand, could benefit from the enriched political understanding associated with classic materialist critique. New materialist strains of cultural studies may also find the vibrancy of matter that underpins many CAM/New Age practices worthy of examination.

    Large scale QCD Monte Carlo calculations have typically been performed on either commercial supercomputers or specially built massively parallel computers such as Fermilab's ACPMAPS. Commodity computer systems offer impressive floating point performance-to-cost ratios which exceed those of commercial supercomputers. As high performance networking components approach commodity pricing, it becomes reasonable to assemble a massively parallel supercomputer from commodity parts. The authors describe the work and progress to date of a collaboration working on this problem

    A number of countries have recently responded to high and volatile commodity prices by setting up commodity funds. In several cases, these funds have proved effective in stabilising government spending and boosting savings, but on the whole they have unfortunately not achieved the hoped-for results.

    In the standard Okishio-Morishima approach, the existence of profits is proved to be equivalent to the exploitation of labour. Yet, it can also be proved that the existence of profits is equivalent to the ‘exploitation’ of any good.

These results are a rejection of the standard competitive model of comm...

  20. Applications of GARCH models to energy commodities

    Science.gov (United States)

    Humphreys, H. Brett

    This thesis uses GARCH methods to examine different aspects of the energy markets. The first part of the thesis examines seasonality in the variance. This study modifies the standard univariate GARCH models to test for seasonal components in both the constant and the persistence in natural gas, heating oil and soybeans. These commodities exhibit seasonal price movements and, therefore, may exhibit seasonal variances. In addition, the heating oil model is tested for a structural change in variance during the Gulf War. The results indicate the presence of an annual seasonal component in the persistence for all commodities. Out-of-sample volatility forecasting for natural gas outperforms standard forecasts. The second part of this thesis uses a multivariate GARCH model to examine volatility spillovers within the crude oil forward curve and between the London and New York crude oil futures markets. Using these results the effect of spillovers on dynamic hedging is examined. In addition, this research examines cointegration within the oil markets using investable returns rather than fixed prices. The results indicate the presence of strong volatility spillovers between both markets, weak spillovers from the front of the forward curve to the rest of the curve, and cointegration between the long term oil price on the two markets. The spillover dynamic hedge models lead to a marginal benefit in terms of variance reduction, but a substantial decrease in the variability of the dynamic hedge; thereby decreasing the transactions costs associated with the hedge. The final portion of the thesis uses portfolio theory to demonstrate how the energy mix consumed in the United States could be chosen given a national goal to reduce the risks to the domestic macroeconomy of unanticipated energy price shocks. An efficient portfolio frontier of U.S. energy consumption is constructed using a covariance matrix estimated with GARCH models. The results indicate that while the electric

  1. Scientific Research: Commodities or Commons?

    Science.gov (United States)

    Vermeir, Koen

    2013-10-01

    Truth is for sale today, some critics claim. The increased commodification of science corrupts it, scientific fraud is rampant and the age-old trust in science is shattered. This cynical view, although gaining in prominence, does not explain very well the surprising motivation and integrity that is still central to the scientific life. Although scientific knowledge becomes more and more treated as a commodity or as a product that is for sale, a central part of academic scientific practice is still organized according to different principles. In this paper, I critically analyze alternative models for understanding the organization of knowledge, such as the idea of the scientific commons and the gift economy of science. After weighing the diverse positive and negative aspects of free market economies of science and gift economies of science, a commons structured as a gift economy seems best suited to preserve and take advantage of the specific character of scientific knowledge. Furthermore, commons and gift economies promote the rich social texture that is important for supporting central norms of science. Some of these basic norms might break down if the gift character of science is lost. To conclude, I consider the possibility and desirability of hybrid economies of academic science, which combine aspects of gift economies and free market economies. The aim of this paper is to gain a better understanding of these deeper structural challenges faced by science policy. Such theoretical reflections should eventually assist us in formulating new policy guidelines.

    We present a two-commodity perishable stochastic inventory system under continuous review at a service facility with a finite waiting room. The maximum storage capacity for the i–th item is fixed as Si (i = 1, 2). We assume that a demand for the i–th commodity is of unit size. The arrival instants of customers to the service station constitutes a Poisson process with parameter lambda. The customer demands for these commodities are assumed to be in the ratio p1:p2.

    Endogenous variables in structural models of agricultural commodity markets are typically treated as stationary. Yet, tests for unit roots have rather frequently implied that commodity prices are not stationary. This seeming inconsistency is investigated by focusing on alternative specifications of unit root tests. We apply various specifications to Illinois farm prices of corn, soybeans, barrows and gilts, and milk for the 1960 through 2002 time span. The preponderance of the evidence sugges...

    In a closed economy, a commodity tax drives a wedge between the producer price and the consumer price. In open economies, intercountry differences in commodity taxation can induce two additional distortions: (1) Cross-country differences in consumer marginal rates of substitution (which result in an inefficient allocation of world consumption), which arise when countries levy taxes on goods and services consumed within their borders (the destination principle). (2) Cross-country differences i...

  13. Managing commodity markets: the case of OPEC

    International Nuclear Information System (INIS)

    Since primary commodity producers first took control of their natural resources, they have attempted to utilize production/price management with varying degrees of success. As a tool aimed at regulating, rather than controlling, commodity markets, this type of resource management is an essential means of achieving realistic economic returns, which, in the long run, serves the interests of the producer of the commodity in question, as well as its consumer. By regulating commodity markets in times of stable prices producing countries would benefit from a steady and constant level of export earnings, thus allowing them to achieve a sustainable level of economic development. As far as the oil market is concerned, stable prices, set in a range favourable to both producers and consumers, would give investors the confidence needed for long-term exploration. This is particularly important for a commodity such as oil, at a time when the lead time between exploration starting and actual production getting under way is increasing. Not only would producers benefit from stable export earnings, which are an essential requirement for the planning of their development process, but consuming countries would at the same time benefit in two ways: first, they would gain security of supply; and second, as fluctuations in their expenditure for this commodity are reduced, they would be a position to manage their economies more efficiently.

    ENGLISH ABSTRACT: This article considers a two-commodity continuous review inventory system in which the arriving customers belong to any one of three types, such that type 1 customers demand a single item of the first commodity, type 2 customers demand bulk items of the second commodity, and type 3 customers demand one item of the first commodity and bulk items of the second commodity. The arrivals of all three types of customers are assumed to be a Markovian arrival process (MAP. It is also assumed that the number of items demanded for the second commodity is a random variable. The ordering policy is to place orders for both commodities when the inventory levels are below prefixed levels for both commodities. The lead time is assumed to have a phase type distribution, and the demands that occur during stock out period are assumed to be lost. The joint probability distribution for both commodities is obtained in the steady state case. Various measures of system performance and the total expected cost rate in the steady state are derived. The results are illustrated with numerical examples.

  16. Energy prices and agricultural commodity prices: Testing correlation using copulas method

    International Nuclear Information System (INIS)

    The linear relationships between energy prices and prices for agricultural commodities such as corn and soybeans may have been affected, over the last several years, by policy legislations in the farm sector, the Energy Independence and Security Act of 2007, and the Renewable Fuel Standard Program for 2014. Using high-frequency data and newer methodology, this study investigates dependence between agricultural commodity futures prices and energy futures prices. Results reveal that agricultural commodity and energy future prices are highly correlated and exhibit positive and significant relationship. Findings from this study highlight that an increase in energy price increases the price of agricultural commodities. - Highlights: • Energy policy mandates production of 15 billion gallons of corn ethanol by 2015. • Energy-intensive agriculture has a link between energy sector and crop production costs. • We investigate correlation between energy prices and agricultural commodity prices. • Agricultural commodity and energy future prices are highly correlated. • Increase in energy price increases the price of agricultural commodity

    Directory of Open Access Journals (Sweden)

    B Sivakumar

    2005-12-01

    Full Text Available We present a two-commodity perishable stochastic inventory system under continuous review at a service facility with a finite waiting room. The maximum storage capacity for the i–th item is fixed as Si (i = 1, 2. We assume that a demand for the i–th commodity is of unit size. The arrival instants of customers to the service station constitutes a Poisson process with parameter lambda. The customer demands for these commodities are assumed to be in the ratio p1:p2. An individual customer is issued a demanded item after a random time of service with a negative exponential distribution. The items are perishable in nature and the life time of items of each commodity is assumed to be exponentially distributed. Both commodities are supposed to be substitutable in the sense that at the instant of any zero-stock, the other item may be used to meet the demand. A joint reordering policy is adopted with a random lead time for orders with exponential distribution. The joint probability distribution of the number of customers in the system and the inventory levels are obtained in both the transient and steady states. We also derive some stationary performance measures. The results are illustrated by means of a numerical example.

  20. The influence of biofuels, economic and financial factors on daily returns of commodity futures prices

    International Nuclear Information System (INIS)

    Biofuels production has experienced rapid growth worldwide as one of the several strategies to promote green energy economies. Indeed, climate change mitigation and energy security have been frequent rationales behind biofuel policies, but biofuels production could generate negative impacts, such as additional demand for feedstocks, and therefore for land on which to grow them, with a consequent increase in food commodity prices. In this context, this paper examines the effect of biofuels and other economic and financial factors on daily returns of a group of commodity futures prices using Generalized Autoregressive Conditional Heteroskedasticity (GARCH) family models in univariate and multivariate settings. The results show that a complex of drivers are relevant in explaining commodity futures returns; more precisely, the Standard and Poor's (S and P) 500 positively affects commodity markets, while the US/Euro exchange rate brings about a decline in commodity returns. It turns out, in addition, that energy market returns are significant in explaining commodity returns on a daily basis, while monetary liquidity is not. This would imply that biofuel policy should be carefully monitored in order to avoid excessive first-generation subsidization, which would trigger a fuel vs. food conflict. - Highlights: • The effects of biofuels and other economic and financial factors on daily returns of commodity futures prices are examined. • A GARCH methodology in univariate and multivariate settings is adopted. • The results show that a complex of drivers is relevant in explaining commodity futures returns. • Energy market returns play a significant role in pushing commodity returns. • The increase in monetary liquidity does not contribute to changes in futures returns on a daily basis

  13. Biofuel and Food-Commodity Prices

    Directory of Open Access Journals (Sweden)

    David Zilberman

    2012-09-01

    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.

  14. Expected commodity returns and pricing models

    International Nuclear Information System (INIS)

    Stochastic models of commodity prices have evolved considerably in terms of their structure and the number and interpretation of the state variables that model the underlying risk. Using multiple factors, different specifications and modern estimation techniques, these models have gained wide acceptance because of their success in accurately fitting the observed commodity futures' term structures and their dynamics. It is not well emphasized however that these models, in addition to providing the risk neutral distribution of future spot prices, also provide their true distribution. While the parameters of the risk neutral distribution are estimated more precisely and are usually statistically significant, some of the parameters of the true distribution are typically measured with large errors and are statistically insignificant. In this paper we argue that to increase the reliability of commodity pricing models, and therefore their use by practitioners, some of their parameters — in particular the risk premium parameters — should be obtained from other sources and we show that this can be done without losing any precision in the pricing of futures contracts. We show how the risk premium parameters can be obtained from estimations of expected futures returns and provide alternative procedures for estimating these expected futures returns. - Highlights: • Simple methodology to improve the performance of commodity pricing models • New information about commodity futures expected return is added to the estimation. • No significant effect in pricing futures contracts is observed. • More reliable commodity pricing model's expected returns are obtained. • Methodology is open to any expected futures return model preferred by practitioner

    Reducing post-harvest food losses is becoming increasingly important for sustaining food supplies. Appropriate post-harvest processing, handling, storage and distribution practices are as important as the efforts to increase productivity for improving food security, food safety and international trade in agricultural commodities. Preservation of food by ionizing radiation involves controlled application of energy of ionizing radiation such as gamma rays, X-rays, and accelerated electrons to agricultural commodities, food products and ingredients, for improving their storage life, hygiene and safety. The process employs either gamma rays emitted by radioisotopes such as cobalt-60 or high-energy electrons or X-rays generated from machine sources

Gambier terms, in addition, to use as the name of the plant, is also the trade name of the product produced by the plant, extract of the leaves and young branches of the gambier plant.  In Indonesia, gambier have been subsisted in a golden era and be the prominent commodity.  In the early 19th century, gambier has become one of the commodities traded in Europe.  After World War II, gambier is no longer an important export products that are traded in the international market.  Further, development of gambier plantations in Indonesia are not so obvious information.  At this time in Indonesia, West Sumatra is the center of gambier production, moreover gambier also called as a specific plants of West Sumatra.  Mostly, gambier is produced by small home industries with the traditional tools and use more human labor.  Gambier is cultivated and processed in a unique method, therefore, gambier plant development become complicated. However, gambier development in Indonesia especially in West Sumatera for the future is still promising, considering its various usefulness and the role of Indonesia as the world's major producer.  Along with to the all contributing factors, there are numerous challenges and obstacles in the development for various aspects of this commodity.  Furthermore, intense participation from the stakeholders; government, farmers, researchers, investors, and traders in management ranging from farming techniques, processing, trade, and institutions are necessary. Thus, it could be expected, gambier would be turn around as a foremost commodity in the future.

  6. Will Commodity Properties Affect Seller's Creditworthy: Evidence in C2C E-commerce Market in China

    Science.gov (United States)

    Peng, Hui; Ling, Min

    This paper finds out that the credit rating level shows significant difference among different sub-commodity markets in E-commerce, which provides room for sellers to get higher credit rating by entering businesses with higher average credit level before fraud. In order to study the influence of commodity properties on credit rating, this paper analyzes how commodity properties affect average crediting rating through the degree of information asymmetry, returns and costs of fraud, credibility perception and fraud tolerance. Empirical study shows that Delivery, average trading volume, average price and complaint possibility have decisive impacts on credit performance; brand market share, the degree of standardization and the degree of imitation also have a relatively less significant effect on credit rating. Finally, this paper suggests that important commodity properties should be introduced to modify reputation system, for preventing credit rating arbitrage behavior where sellers move into low-rating commodity after being assigned high credit rating.

    In the present period of instability on financial markets, investments in commodities are the solution for elimination of the consequences of inflation and ensure the yield. When investing in commodities, the use of specifics of commodities compared to other assets. The distribution of commodities we can interpret for agricultural commodities, commodities of energy, precious and other metals, and weather. Therefore, in the framework of the investment portfolio are the commodities. This is the reason why one of the most popular types of investment assets now become commodities. In the interpretation of particular commodities we talk about commodity futures. The reason is that the spot market with commodities is limited storage facilities. The growth of the popularity, which allows a wide range of commodities, has caused that in addition to from institutional investors and speculators for trade may involve even small investors. This development will be supplemented by interpretation of the charts and figers, which will be commented and used for generalization of knowledge. Finally, the article will be interpreted by the further development of the market for commodities as it by article assumes from the results of research.

  10. Valuing embryos as both commodities and singularities.

    Science.gov (United States)

    Legge, Michael; Fitzgerald, Ruth

    2016-03-11

    An argument put forward against gamete and embryo donation, sale and research, is that to do so would treat the gametes or embryos as objects with no intrinsic value as human. Instead, gametes and embryos created and used for donation, sale or research, can be considered more like a commodity created and traded for economic exchange--something that is valuable only for the amount of money or other goods and services that others are willing to exchange. While Kant asserts that humans have dignity rather than object worth, the provision of human gametes and embryos are progressively becoming utilities for resolving childlessness and for certain research investigations. In this paper we discuss the commodity market and the relationship to human reproduction material. PMID:27005877

    During September 2009, we performed a rapid cross-sectional study to investigate the extent of aflatoxin contamination among common Bangladeshi foods. We collected eight common human food commodities (rice, lentils, wheat flour, dates, betelnut, red chili powder, ginger and groundnuts) and poultry feed samples from two large markets in each of three cities in Bangladesh. We quantified aflatoxin levels from pooled subsamples using fluorescence high-performance liquid chromatography. Aflatoxin levels were highest in dates and groundnuts (maximum 623 and 423 ng/g), respectively. Samples of betelnut (mean 30.6 ng/g), lentils (mean 21.2 ng/g) and red chili powder (>20 ng/g) also had elevated levels. The mean aflatoxin level among poultry feed samples was 73.0 ng/g. Aflatoxin levels were above the US maximum regulatory levels of 20 ng/g in five of eight commonly ingested human food commodities tested. PMID:24786620

  12. GENERIC COMMODITY PROMOTION AND PRODUCT DIFFERENTIATION

    OpenAIRE

    John M Crespi

    1999-01-01

    This paper considers whether generic promotion lowers the differentiation among competing brands as claimed in the 1997 Supreme Court case (Wileman et al. v. Glickman). Commodity promotion is modeled as a multi-stage game where products are vertically differentiated. Analytical results show that if the benefits of generic advertising from increased demand are outweighed by the costs from lower product differentiation then high-quality producers will not benefit from generic promotion but prod...

    We investigate the optimal collection and expenditure of funds for agricultural commodity promotion in markets where the processing and distribution sectors may exhibit oligopoly and/or oligopsony power. The conditions that characterize optimal advertising intensity under perfect competition for funds generated from either per-unit or lump-sum taxes do not, in general, hold when marketing is imperfectly competitive. Simulation analyses show that imperfect competition always reduces farmers' o...

  14. Securitization and Commodity Contingency in International Lending

    OpenAIRE

    Ronald W. Anderson; Gilbert, Christopher L.

    1989-01-01

    Securitization of LDC debt would significantly aid the international debt problem by increasing liquidity and expanding the range of investors. Securitization is problematic, however, in large part due to sovereign risks involved. At present sovereign risks, commodity price risks and currency risks remain unbundled in general obligation loan contracts. Using a game theoretic model we illustrate the need to separate sovereign risks from other risks and associate the sovereign default with a th...

    A retailer has different opportunities to advertise in the media: emphasizing the store image or promoting specifically its private label (PL). In the first option, advertising benefits all products sold, whereas in the alternative, only store brands are concerned by image improvement. We analyze the retailer's advertising campaign strategies when its competitor's format is a small commodity store. PL quality is endogenous and chosen according to the competitor's product range.

  16. LNG: a commodity in the making

    International Nuclear Information System (INIS)

    Although still far from being a commodity, LNG is undoubtedly emerging as an essential vector for world gas expansion. The flexibility it procures in terms of supply is of prime importance for future market equilibrium. Despite a number of uncertainties and constraints liable to thwart the realisation of the most optimistic growth prospects, the LNG trade remains wedded to rapid growth of about 7%/year by 2020, boosting its share of world gas trade to some 38% by that horizon.

  3. LDC commodity risk analysis and recommendations

    International Nuclear Information System (INIS)

    Under the current operation of the new competitive electricity market in Ontario, local distribution companies (LDCs) are required to pay the monthly invoice of the Independent Market Operator (IMO) before they collect from end-users for the consumption period covered by the invoice, with no clear guarantee that the recovery will occur. This situation creates a major cash flow problem and financial risk for LDCs and threatens the integrity and stability of the electricity market. This paper described 3 features of Ontario's competitive electricity market that create financial and commodity risk. The first problem is that there is no limit on how high prices can rise. Increases in wholesale commodity prices can result in a situation where the amount of the IMO's invoice is greater than the LDC's ability to pay at the time of receipt. Secondly, the LDC bears a 100 per cent payment obligation to the IMO administrator of the wholesale market. The third problem is that LDCs bear payment default risk from all consumers in the Ontario market, including electricity retailers. This paper presents some specific policy solutions that can protect the market from this threat. It was suggested that in order to protect the integrity of Ontario's electricity market during high prices, a policy must be drafted to address the commodity price financing risk (CPFR) issue. The policy must also define what happens if prices increase past the LDCs financing obligation limit. tabs., figs

    We analyze daily prices of 29 commodities and 2449 stocks, each over a period of $\\approx 15$ years. We find that the price fluctuations for commodities have a significantly broader multifractal spectrum than for stocks. We also propose that multifractal properties of both stocks and commodities can be attributed mainly to the broad probability distribution of price fluctuations and secondarily to their temporal organization. Furthermore, we propose that, for commodities, stronger higher orde...

  2. Towards a Gendered Agro-Commodity Approach

    Directory of Open Access Journals (Sweden)

    Primrose Nakazibwe

    2015-08-01

    Full Text Available Commodity or value chains are the dominant means to channel agro-food products from cultivators to consumers. Direct open markets are either non-existent or insignificant . These chains are also the main mechanisms for integrating underprivileged groups into the world economy. Why do global value chains generate sorrow for many and joy for a few, and why are these outcomes heavily gender biased? To look for answers this article critically reviews the post-2000 and earlier gender literature by proponents and opponents of the mainstream value chain approach. The purpose is to provide a methodological contribution on the integration of gender into the commodity chain approach. Most studies have fo cused on the economic effects of chain dynamics on women in agricultural product and labor markets. Some have extended this reasoning with social and cultural effects. Despite these advances, analytical gaps still exist as most existing research has concentrated on the agricultural nodes of modern, high value chains and lacks a gendered conceptual foundation. Scarce attention has been given to traditional staple crops, non-agricultural nodes, and feed back effects of gender relations on the chain. Our results indicate that an appropriate GCC approach should also consider the gendered impacts of the interaction between the governance structure and the institutiona l embeddedness, as well as the consequences of intra-household division of resources and labor in all stages of the chain. These two conceptual complements will be needed to explain the opportunities and constraints to improve gender equity in traditional and modern agro-commodity chains.

  3. Factor Structure in Commodity Futures Return and Volatility

    DEFF Research Database (Denmark)

    Christoffersen, Peter; Lunde, Asger; Olesen, Kasper Vinther

    Using data on more than 750 million futures trades during 2004-2013, we analyze eight stylized facts of commodity price and volatility dynamics in the post financialization period. We pay particular attention to the factor structure in returns and volatility and to commodity market integration with...... the equity market. We find evidence of a factor structure in daily commodity futures returns. However, the factor structure in daily commodity futures volatility is even stronger than in returns. When computing model-free realized commodity betas with the stock market we find that they were high...... during 2008-2010 but have since returned to the pre-crisis level close to zero. The common factor in commodity volatility is nevertheless clearly related to stock market volatility. We conclude that, while commodity markets appear to again be segmented from the equity market when only returns are...

  4. The stochastic seasonal behavior of energy commodity convenience yields

    International Nuclear Information System (INIS)

    This paper contributes to the commodity pricing literature by consistently modeling the convenience yield with its empirically observed properties. Specifically, in this paper, we show how a four-factor model for the stochastic behavior of commodity prices, with two long- and short-term factors and two additional seasonal factors, may accommodate some of the most important empirically observed characteristics of commodity convenience yields, such as the mean reversion and stochastic seasonality. Based on this evidence, a theoretical model is presented and estimated to characterize the commodity convenience yield dynamics that are consistent with previous findings. We also show that commodity price seasonality is better estimated through convenience yields than through futures prices. - Highlights: • Energy commodity convenience yields exhibit mean reversion and stochastic seasonality. • We present a model for convenience yields accounting for their observed characteristics. • Commodity price seasonality is better estimated through convenience yields

    We study here numerically the behavior of an ideal gas like model of markets having only one non-consumable commodity. We investigate the behavior of the steady-state distributions of money, commodity and total wealth, as the dynamics of trading or exchange of money and commodity proceeds, with local (in time) fluctuations in the price of the commodity. These distributions are studied in markets with agents having uniform and random saving factors. The self-organizing features in money distribution are similar to the cases without any commodity (or with consumable commodities), while the commodity distribution shows an exponential decay. The wealth distribution shows interesting behavior: gamma like distribution for uniform saving propensity and has the same power-law tail, as that of the money distribution, for a market with agents having random saving propensity.

    Sonstegaard, M.

    1975-01-01

    Large airships may prove feasible as carriers of commodities that move as gases or cryogenic liquids; buoyant gaseous cargo could be ballasted with liquid cargo. Airships are compact in shape, operate in a rarified medium, and hence can be fast and perhaps economic carriers of costly cryogenic tanks. The high-pressure gas pipeline has excessive surface area when carrying hydrogen and excessive fluid density when carrying natural gas, while the cryogenic ocean tanker runs in a dense medium and makes gravity waves. But the airship, despite its fluid dynamic advantages, faces problems of safety, weather, and altitude control.

  10. Voluntary medical male circumcision: logistics, commodities, and waste management requirements for scale-up of services.

    Directory of Open Access Journals (Sweden)

    Dianna Edgil

    2011-11-01

    Full Text Available BACKGROUND: The global HIV prevention community is implementing voluntary medical male circumcision (VMMC programs across eastern and southern Africa, with a goal of reaching 80% coverage in adult males by 2015. Successful implementation will depend on the accessibility of commodities essential for VMMC programming and the appropriate allocation of resources to support the VMMC supply chain. For this, the United States President's Emergency Plan for AIDS Relief, in collaboration with the World Health Organization and the Joint United Nations Programme on HIV/AIDS, has developed a standard list of commodities for VMMC programs. METHODS AND FINDINGS: This list of commodities was used to inform program planning for a 1-y program to circumcise 152,000 adult men in Swaziland. During this process, additional key commodities were identified, expanding the standard list to include commodities for waste management, HIV counseling and testing, and the treatment of sexually transmitted infections. The approximate costs for the procurement of commodities, management of a supply chain, and waste disposal, were determined for the VMMC program in Swaziland using current market prices of goods and services. Previous costing studies of VMMC programs did not capture supply chain costs, nor the full range of commodities needed for VMMC program implementation or waste management. Our calculations indicate that depending upon the volume of services provided, supply chain and waste management, including commodities and associated labor, contribute between US$58.92 and US$73.57 to the cost of performing one adult male circumcision in Swaziland. CONCLUSIONS: Experience with the VMMC program in Swaziland indicates that supply chain and waste management add approximately US$60 per circumcision, nearly doubling the total per procedure cost estimated previously; these additional costs are used to inform the estimate of per procedure costs modeled by Njeuhmeli et al. in

  11. Education: Commodity, Come-On, or Commitment?

    Science.gov (United States)

    Moore, John W.

    2000-07-01

    July 4, and the glass art shown on pages 812-816, remind us that freedom is fragile. Through their governments, citizens of democracies have traditionally made strong commitments to education on grounds that without it individuals would not be able to act responsibly and to make wise decisions in voting booths and public meetings. All citizens have a stake in everyone's education, because a better-educated citizenry benefits all of society. In this country such a commitment has produced a system of public schools and public universities that offers opportunities to many who otherwise could not afford a level of education commensurate with their talents. But there are signs that this commitment to public education is flagging. Many students, teachers, and administrators view education as merely a way to enhance personal prosperity. How often have you heard the statistic that a college education pays for itself through increased earning power, even if it costs $20,000-30,000 per year? Investing in education pays off just as investing in the stock market does, provided you wait long enough. Attending a better school gets you a better job and a better income. In other words, a certified level of education is a commodity-something that is useful and can be turned to commercial advantage. Viewing education as a commodity has several consequences. First, if education is a means to better employment rather than better citizenship, why should anyone pay for it other than the person who benefits? Why should I pay taxes to help someone else get a better job when I could be spending the money for my own benefit? Education as a commodity makes such attitudes reasonable, though not commendable, and the result is lessened support for public education. Second, those who supply education as an economic good should be rewarded, and those who are much better at educating should be rewarded much more. Hence the fear of Arthur Levine, president of Teachers College, Columbia University

A major milestone of food irradiation was reached in the country when Board of Radiation and Isotope Technology, a constituent unit of Department of Atomic Energy had set up 'SPICE PLANT' at Vashi, Navi Mumbai in the year 2000. It was first demonstration plant for radiation processing of spices for hygienisation purpose. For expanding scope of applications in agricultural sector, the next step in this direction was taken by BARC for setting up 'KRUSHAK' plant at Lasalgaon, Nashik. This was the first plant for low dose application of gamma radiation in agricultural commodities i.e. for sprout inhibition in onion and potatoes

  14. From creation to consumption: objects and commodities

    Directory of Open Access Journals (Sweden)

    Angélica Bautista López

    2008-11-01

    Full Text Available Objects, persons and ideas are all merely merchandise in a world that is highly industrialised and utterly superficial. Consumer societies produce a profusion of merchandise. In strictly economic terms, merchandise is whatever has an exchange-value, in  a world where objects are valued for their utility. So goods are whatever is useful, where use can be measured in monetary terms. This perspective impoverishes social relations. People relate only insofar as their value dictates, and that value is merely utilitarian. Moreover, this commercialisation reaches up to impoverish society as a whole. All this is the result of a long process of objectification which, seeing the world as the exchange of goods, ends up treating people just like any other tradable commodity. This article takes a critical look at the processes involved, and proposes an explanation in terms of the social construction of 'utility''.

  15. Caos en el mercado de commodities

    Directory of Open Access Journals (Sweden)

    Espinosa Méndez Christian

    2010-12-01

    Full Text Available Este artículo aplica seis técnicas y herramientas (análisis gráfico, gráfico de recurrencia, entropía de espacio temporal, coeficiente de Hurst, exponente de Lyapunov y dimensión de correlación, a las series de retornos del cobre, oro, petróleo, plata, zinc, aluminio, plomo y níquel, con el fin de corroborar la existencia de un comportamiento caótico en el mercado de commodities. Se encuentra evidencia de que los mercados financieros se comportan de forma caótica en contra de la hipótesis de aleatoriedad. Se contrasta, igualmente, no-normalidad, no-aleatoriedad y no-linealidad. Los resultados encontrados contradicen algunos de los supuestos básicos de la teoría financiera moderna.

  16. Dynamic analysis of policy drivers for bioenergy commodity markets

    International Nuclear Information System (INIS)

    Biomass is increasingly being considered as a feedstock to provide a clean and renewable source of energy in the form of both liquid fuels and electric power. In the United States, the biofuels and biopower industries are regulated by different policies and have different drivers, which impact the maximum price the industries are willing to pay for biomass. This article describes a dynamic computer simulation model that analyzes future behavior of bioenergy feedstock markets given policy and technical options. The model simulates the long-term dynamics of these markets by treating advanced biomass feedstocks as a commodity and projecting the total demand of each industry, as well as the market price over time. The model is used for an analysis of the United States bioenergy feedstock market that projects supply, demand, and market price given three independent buyers: domestic biopower, domestic biofuels, and foreign exports. With base-case assumptions, the biofuels industry is able to dominate the market and meet the federal Renewable Fuel Standard (RFS) targets for advanced biofuels. Further analyses suggest that United States bioenergy studies should include estimates of export demand in their projections, and that GHG-limiting policy would partially shield both industries from export dominance. - Highlights: ► We model a United States bioenergy feedstock commodity market. ► Three buyers compete for biomass: biopower, biofuels, and foreign exports. ► The presented methodology improves on dynamic economic equilibrium theory. ► With current policy incentives and ignoring exports, biofuels dominates the market. ► Overseas biomass demand could dominate unless a CO2-limiting policy is enacted.

    2010-01-01

    In this paper we examine linkages across non-energy commodity price developments by means of a factor-augmented VAR model (FAVAR). From a set of non-energy commodity price series, we extract two factors, which we identify as common trends in metals and a food prices. These factors are included in a FAVAR model together with selected macroeconomic variables, which have been associated with developments in commodity prices. Impulse response functions confirm that exchange rates and of economic ...

  19. A GENERAL APPROACH TO VALUING COMMODITY-LINKED BONDS

    OpenAIRE

    Jin, Yufei; Turvey, Calum G.

    2004-01-01

    The purpose of this paper is to develop a general approach to valuing commodity-linked bonds (CLBs) based on the Heath-Jarrow-Morton (HJM) framework. The model deals with four dimensions of uncertainty: prices of the underlying commodity, the value of firm that issues bonds, interest rates, and convenience yields. A mathematical formula for the price of a commodity-linked bond is derived. The previous results in Black and Scholes (1973), Merton (1973), Schwartz (1982), and Atta-Mensah (1992) ...

  20. Futures trading and the excess comovement of commodity prices

    OpenAIRE

    Le Pen, Yannick; Sévi, Benoît

    2013-01-01

    We empirically reinvestigate the issue of excess comovement of commodity prices initially raised in Pindyck and Rotemberg (1990) and show that excess comovement, when it exists, can be related to hedging and speculative pressure in commodity futures markets. Excess comovement appears when commodity prices remain correlated even after adjusting for the impact of common factors. While Pindyck and Rotemberg and following c ontributions examine this issue using a relevant but arbitrary set of con...

  1. The present value model of rational commodity pricing

    OpenAIRE

    Robert S. Pindyck

    1991-01-01

    The present value model relates an asset's price to the sum of its discounted expected future payoffs. I explore the limits of the model by testing its ability to explain the pricing of storable commodities. For commodities the payoff stream is the convenience yield that accrues from holding inventories, and it can be measured directly from spot and futures prices. Hence the model imposes restrictions on the joint dynamics of spot and futures prices, which I test for four commodities. I find ...

    This article examines a two commodity substitutable inventory system—two different brands of super computers under continuous review. The demand points for each commodity are assumed to form independent Poisson processes. The reordering policy is to place orders for both the commodities when the total net inventory level drops to any one of the prefixed levels with prescribed probability distribution. Lost sales are assumed during the stock out period. The lead time for a reorder is exponen...

    This paper studies the effect of switching from the destination to the origin principle of taxation on non-cooperative commodity tax equilibrium. When taxes are constrained to uniformity across commodities, the switch has no effect. When differentiated taxes are allowed, the effects of the switch depend on whether countries are small or large. In both cases the switch imposes the requirement that taxes must be uniform across commodities within each country. In the second case there are two fu...

  7. Education: Commodity, Come-On, or Commitment?

    Science.gov (United States)

    Moore, John W.

    2000-07-01

    July 4, and the glass art shown on pages 812-816, remind us that freedom is fragile. Through their governments, citizens of democracies have traditionally made strong commitments to education on grounds that without it individuals would not be able to act responsibly and to make wise decisions in voting booths and public meetings. All citizens have a stake in everyone's education, because a better-educated citizenry benefits all of society. In this country such a commitment has produced a system of public schools and public universities that offers opportunities to many who otherwise could not afford a level of education commensurate with their talents. But there are signs that this commitment to public education is flagging. Many students, teachers, and administrators view education as merely a way to enhance personal prosperity. How often have you heard the statistic that a college education pays for itself through increased earning power, even if it costs $20,000-30,000 per year? Investing in education pays off just as investing in the stock market does, provided you wait long enough. Attending a better school gets you a better job and a better income. In other words, a certified level of education is a commodity-something that is useful and can be turned to commercial advantage. Viewing education as a commodity has several consequences. First, if education is a means to better employment rather than better citizenship, why should anyone pay for it other than the person who benefits? Why should I pay taxes to help someone else get a better job when I could be spending the money for my own benefit? Education as a commodity makes such attitudes reasonable, though not commendable, and the result is lessened support for public education. Second, those who supply education as an economic good should be rewarded, and those who are much better at educating should be rewarded much more. Hence the fear of Arthur Levine, president of Teachers College, Columbia University

  11. The output effects of commodity price volatility: Evidence from exporting countries

    OpenAIRE

    Empirical evidence indicates that high oil price volatility has a dampening effect on output in countries that import commodities. Many countries, however, gain important revenues from commodity exports. This paper investigates the output effects of commodity price volatility in commodity exporting countries accounting for both oil and non-oil commodities. To that aim, we construct country specific commodity price indices for a sample of oil and non-oil commodity exporters. We find a signific...

    Commodity price volatility in international markets has been used to justify numerous policy interventions, including the need for buffer stocks and counter-cyclical payments. The common measure of volatility, the standard deviation or coefficient of variation, likely overstates the actual variation faced by economic agents. By making a distinction between its predictable and unpredictable components, volatility is found to be low, suggesting that significant welfare gains may be unattainable...

  19. Live HDR video streaming on commodity hardware

    Science.gov (United States)

    McNamee, Joshua; Hatchett, Jonathan; Debattista, Kurt; Chalmers, Alan

    2015-09-01

    High Dynamic Range (HDR) video provides a step change in viewing experience, for example the ability to clearly see the soccer ball when it is kicked from the shadow of the stadium into sunshine. To achieve the full potential of HDR video, so-called true HDR, it is crucial that all the dynamic range that was captured is delivered to the display device and tone mapping is confined only to the display. Furthermore, to ensure widespread uptake of HDR imaging, it should be low cost and available on commodity hardware. This paper describes an end-to-end HDR pipeline for capturing, encoding and streaming high-definition HDR video in real-time using off-the-shelf components. All the lighting that is captured by HDR-enabled consumer cameras is delivered via the pipeline to any display, including HDR displays and even mobile devices with minimum latency. The system thus provides an integrated HDR video pipeline that includes everything from capture to post-production, archival and storage, compression, transmission, and display.

  20. Commodity chemical growth to slow in 1993

    International Nuclear Information System (INIS)

    In their latest chemical outlook, DRI/McGraw-Hill economists characterize 1992 as a peak year for U.S. commodity chemical demand growth, at 4.2%, tapering off to a compound 2.2% between 1993 and 1995. Just as operating rates begin to reach higher levels in 1995, however, DRI forecasts slowing GNP growth. DRI's Ramunas J. Svarcas expects a decline in exports. Those plastics promising the rosiest consumption outlook include melamine-formaldehyde resin, up 9.9% in 1992, from 155 million lbs in 1991, and projected to grow 8.6%/year through 1995; styrene acrylonitrile resin, up 23% this year, from 58 million lbs last year, and growing 8.2%/year through 1995; and unsaturated polyester, up 11.7% this year, from 1.07 billion lbs in 1991, and increasing at 6.5%/year. Methanol is a bright spot, with consumption growing 4.7%, from 11.2 billion lbs in 1991 and 12%/year thereafter. Ortho-xylene managed an impressive 21% rebound from a depressed 1991 level of 783 million lbs, and is expected to continue its recovery at 7.7%/year

  1. Natural gas : a highly lucrative commodity

    International Nuclear Information System (INIS)

    Exploration and production of natural gas has become highly profitable as natural gas is becoming a leading future commodity. With new technology, high demand and environmental benefits, natural gas is the preferred choice over petroleum as the leading source of energy to heat home and businesses. Canada is the world's third largest producer of natural gas with its Sable Offshore Energy Project being the fourth largest producing natural gas basin in North America. The basin will produce high quality sweet natural gas from 28 production wells over the course of the next 20 to 25 years. The gas will be transported to markets through Nova Scotia, New Brunswick and into the Northeastern United States via the Maritimes and Northeast Pipeline. The 1051 kilometer underground gas pipeline is currently running laterals to Halifax, Nova Scotia and Saint John, New Brunswick. Market studies are being conducted to determine if additional lines are needed to serve Cape Breton, Prince Edward Island and northern New Brunswick. A recent survey identified the following 5 reasons to convert to natural gas: (1) it is safe, (2) it is reliable, (3) it is easy to use, (4) it is cleaner burning and environmentally friendly compared to other energy sources, and (5) it saves the consumer money

  2. OPEC and other commodity cartels: a comparison

    International Nuclear Information System (INIS)

    The economic literature provides specific characteristics for cartels. Although the theory of international cartels in not well developed in the literature, and every cartel is unique, some of these characteristics exist in each cartel. This study investigates the existence of these characteristics in six known commodity cartels including OPEC. In addition, it compares the oil companies' cartel, 'the Seven Sisters', to OPEC, and summarizes the findings of OPEC econometric models developed in the literature in the last 25 years and concludes that the results do not support cartel or competitive models for OPEC. Although other cartels are more successful than OPEC, many books and articles in economics use OPEC as a cartel example. Neither statistical tests nor theory support the popular use of OPEC as a cartel example. Indeed, this article concludes that OPEC is composed of Saudi Arabia, the dominant world producer, plus several distinct sub-groups and that separate models are required to explain the behavior of each. Assigning the power of some OPEC members to OPEC has caused confusion about its behavior. Recent OPEC success is attributed to political, natural, and technical capacity limitations in the oil fields that prevented countries from cheating on their quota. In other words, OPEC adherence to the quota, except for Saudi Arabia, is anything but voluntary. (author)

    2002-11-01

    In order to cost-effectively facilitate mid-scale serial and parallel computations and code development, a number of commodity-based clusters have been built at PPPL. A recent addition is the PETREL cluster, consisting of 100 dual-processor machines, both Intel and AMD, interconnected by a 100Mbit switch. Sixteen machines have an additional Myrinet 2000 interconnect. Also underway is the implementation of a Prototype Topical Computing Facility which will explore the effectiveness and scaling of cluster computing for larger scale fusion codes, specifically including those being developed under the SCIDAC auspices. This facility will consist of two parts: a 64 dual-processor node cluster, with high speed interconnect, and a 16 dual-processor node cluster, utilizing gigabit networking, built for the purpose of exploring grid-enabled computing. The initial grid explorations will be in collaboration with the Princeton University Institute for Computational Science and Engineering (PICSciE), where a 16 processor cluster dedicated to investigation of grid computing is being built. The initial objectives are to (1) grid-enable the GTC code and an MHD code, making use of MPICH-G2 and (2) implement grid-enabled interactive visualization using DXMPI and the Chromium API.

  12. Multiple pathways of commodity crop expansion in tropical forest landscapes

    International Nuclear Information System (INIS)

    Commodity crop expansion, for both global and domestic urban markets, follows multiple land change pathways entailing direct and indirect deforestation, and results in various social and environmental impacts. Here we compare six published case studies of rapid commodity crop expansion within forested tropical regions. Across cases, between 1.7% and 89.5% of new commodity cropland was sourced from forestlands. Four main factors controlled pathways of commodity crop expansion: (i) the availability of suitable forestland, which is determined by forest area, agroecological or accessibility constraints, and land use policies, (ii) economic and technical characteristics of agricultural systems, (iii) differences in constraints and strategies between small-scale and large-scale actors, and (iv) variable costs and benefits of forest clearing. When remaining forests were unsuitable for agriculture and/or policies restricted forest encroachment, a larger share of commodity crop expansion occurred by conversion of existing agricultural lands, and land use displacement was smaller. Expansion strategies of large-scale actors emerge from context-specific balances between the search for suitable lands; transaction costs or conflicts associated with expanding into forests or other state-owned lands versus smallholder lands; net benefits of forest clearing; and greater access to infrastructure in already-cleared lands. We propose five hypotheses to be tested in further studies: (i) land availability mediates expansion pathways and the likelihood that land use is displaced to distant, rather than to local places; (ii) use of already-cleared lands is favored when commodity crops require access to infrastructure; (iii) in proportion to total agricultural expansion, large-scale actors generate more clearing of mature forests than smallholders; (iv) property rights and land tenure security influence the actors participating in commodity crop expansion, the form of land use displacement

We propose five hypotheses to be tested in further studies: (i) land availability mediates expansion pathways and the likelihood that land use is displaced to distant, rather than to local places; (ii) use of already-cleared lands is favored when commodity crops require access to infrastructure; (iii) in proportion to total agricultural expansion, large-scale actors generate more clearing of mature forests than smallholders; (iv) property rights and land tenure security influence the actors participating in commodity crop expansion, the form of land use displacement

  15. Is health care a right or a commodity? Implementing mental health reform in a recession.

    Science.gov (United States)

    Aggarwal, Neil Krishan; Rowe, Michael; Sernyak, Michael A

    2010-11-01

    The Patient Protection and Affordable Care Act, signed into law by President Obama in March 2010, contains elements of two seemingly contradictory positions: health care as a commodity and as a right. The commodity argument posits that the marketplace should govern demand, supply, and costs of care. The law's establishment of state insurance exchanges reflects this position. The argument that health care is a right posits that it is a need, not a choice, and that government should regulate care standards that may be compromised as insurers attempt to minimize costs. The law's requirement for coverage of mental and substance use disorders reflects this position. This Open Forum examines these arguments in light of current state fiscal crises and impending reforms. Despite the federal government's interest in expanding prevention and treatment of mental illness, states may demonstrate varying levels of commitment, based in part on their perception of health care as a right or a commodity. The federal government should outline clear performance standards, with minimum services specified to maximize state commitments to services. PMID:21041355

  16. Modeling Multi-commodity Trade Information Exchange Methods

    CERN Document Server

    Traczyk, Tomasz

    2012-01-01

    Market mechanisms are entering into new fields of economy, in which some constraints of physical world, e.g. Kirchoffs Law in power grid, must be taken into account during trading. On such markets, some of commodities, like telecommunication bandwidth or electrical energy, appear to be non-storable, and must be exchanged in real-time. On the other hand, the markets tend to react at shortest possible time, so an idea to delegate some competency to autonomous software agents is very attractive. Multi-commodity mechanism addresses the aforementioned requirements. Modeling the relationships between the commodities allows to formulate new, more sophisticated models and mechanisms, which reflect decision situations in a better manner. Application of multi-commodity approach requires solving several issues related to data modeling, communication, semantics aspects of communication, reliability, etc. This book answers some of the questions and points out promising paths for implementation and development.

  17. Monetary policy and world commodity markets: 2000-2007

    Directory of Open Access Journals (Sweden)

    Hossein Askari

    2010-01-01

    Full Text Available Expansionary monetary policy in key industrial countries and a rapidly depreciating US dollar sent commodity prices soaring at unprecedented rates during 2003–2007. In contrast, consumer price indices in major OECD countries, a leading indicator for monetary policy, showed almost no inflation. This twin development is a puzzle as the evolution of consumer prices were not responsive to record low interest rates, doubledigit commodity inflation, and a sharp depreciation of the dollar. A common trend, identified as a monetary shock, drives commodity prices. Policymakers face a policy dilemma: maintain expansionary monetary policy stance with persistent commodity price inflation, subsequent severe world recession, and financial disorder, or tighten monetary policy with subsequent sustained economic growth and financial and price stability.

    1994-09-01

    Part of a comprehensive study of fungi occurring in commodities in Thailand, this paper reports results from 276 samples of mung beans, rice, sorghum and soybeans as well as other minor crops. Samples for major commodities were taken from farmers' stocks, middlemen and retail outlets, while those for minor crops were mostly from retail. Each sample was divided into two portions, one being examined in Bangkok and the second at North Ryde. Mycological examinations were carried out by direct plating after surface disinfection in chlorine. Media used were dichloran rose bengal chloramphenicol agar, dichloran 18% glycerol agar, Aspergillus flavus and parasiticus agar and dichloran chloramphenicol peptone agar. Fungi were identified to species level and percentage infection of samples calculated. The dominant fungus found in mung beans was Fusarium semitectum, which was present in 40% of samples and at a high level (18% of all seeds) overall. Aspergillus flavus was also found in 40% of samples, but only in 2% of seeds overall. Lasiodiplodia theobromae was the only other fungus exceeding 1% total infection. The major fungi found in soybeans were A. flavus (67% of samples; 6% overall) and Cladosporium cladosporioides (49% of samples; 9% overall). Storage fungi were more common in soybeans than the other commodities, indicating longer or adverse storage. Paddy rice contained high levels of a wide variety of field fungi, notably Fusarium semitectum, Bipolaris oryzae, and Curvularia, Phoma and Colletotrichum species. However, probably due to the heat generated by milling, milled rice contained very few fungi, which were mostly of storage origin. Only 3% of particles examined contained internal fungi. Infection in sorghum was typical of oilseeds, dominated by Aspergillus flavus, which was present in 86% of samples, with an overall infection rate of 12%. Beans other than soybeans were infected by a wide range of field fungi, but at low levels, with less than half of seeds

To this end, we generalize the model of excess comovement, originated by Pindyck and Rotemberg (1990) and extended by Deb, Trivedi, and Varangis (1996), to develop the smooth-transition dynamic conditional correlation (STDCC) model that can capture long-run trends and short-run dynamics in excess comovements.

    2016-01-13

    A review is made of the statistical generalization of microeconomics by Baaquie (Baaquie 2013 Phys. A 392, 4400-4416. (doi:10.1016/j.physa.2013.05.008)), where the market price of every traded commodity, at each instant of time, is considered to be an independent random variable. The dynamics of commodity market prices is given by the unequal time correlation function and is modelled by the Feynman path integral based on an action functional. The correlation functions of the model are defined using the path integral. The existence of the action functional for commodity prices that was postulated to exist in Baaquie (Baaquie 2013 Phys. A 392, 4400-4416. (doi:10.1016/j.physa.2013.05.008)) has been empirically ascertained in Baaquie et al. (Baaquie et al. 2015 Phys. A 428, 19-37. (doi:10.1016/j.physa.2015.02.030)). The model's action functionals for different commodities has been empirically determined and calibrated using the unequal time correlation functions of the market commodity prices using a perturbation expansion (Baaquie et al. 2015 Phys. A 428, 19-37. (doi:10.1016/j.physa.2015.02.030)). Nine commodities drawn from the energy, metal and grain sectors are empirically studied and their auto-correlation for up to 300 days is described by the model to an accuracy of R(2)>0.90-using only six parameters.

  14. Portfolio Diversification with Commodities in Times of Financialization

    Directory of Open Access Journals (Sweden)

    2015-03-01

    Full Text Available The study concentrates on the benefits of passive commodity investments in the context of the phenomenon of financialization. The research investigates the implications of increase in the correlation coefficients between equity and commodity investments for investors in financial markets. The paper is composed of several parts. First, the attributes of commodity investments and their benefits in the portfolio optimization are explored. Second, the phenomenon of the financialization is described and the research hypothesis is developed. Next, an empirical analysis is performed. I simulate the mean-variance spanning tests to examine the benefits of commodity investments before and after accounting for the impact of financialization. I proceed separate analysis for pre- and post-financialization period. The empirical research is based on asset classes’ returns and other related variables from years 1991-2012. The performed investigations indicate that the market financialization may have significant implications for commodity investors. Due to increase in correlation coefficients, the inclusion of the commodity futures in the traditional stock-bond portfolio appears to be no longer reasonable.

    correlation with 1h data from a Federal Equivalent Method (FEM) beta-attenuation data, prototype instruments performed as well as commercially available equipment costing considerably more, and as well as another reference instrument under similar conditions at the same timescale (R2 = 0.6). Correlations were stronger when 24 h integrating times were used instead (R2 = 0.72). Chapter 4 replicates and extends the results of Chapter 3, showing that similar calibrations may be reasonably exchangeable between near-roadway and background monitoring sites. Chapter 4 also employs triplicate sensors to obtain data consistent with near-field (transport, and may also facilitate timely and empirical verification of interventions to reduce emissions and exposures, in many important contexts (e.g., the provision of improved cookstoves; congestion pricing; mitigation policies attached to infill development; etc.). They also demonstrate that calibrations against continuous reference monitoring equipment could be remotely transferred, within practical tolerances, to reasonably sized and adequately resourced participatory monitoring campaigns, with minimal risk of disruption to existing monitoring infrastructure (i.e., established monitoring sites). Given a collaborator with a short window of access to a reference monitoring site, this would overcome a nominally important barrier associated with non-gravimetric, in-situ calibration of continuous PM2.5 monitors. Progressive and disruptive prospects linked to a proliferation of comparable sensing technologies based on commodity hardware are discussed in Chapter 5.

  16. Processing of food and agricultural commodities with electron beam from microtron

    International Nuclear Information System (INIS)

    A microtron machine source installed by the Centre for Advanced Technology (CAT), Indore, at Mangalore University, was used in the study. The machine was operated at a beam power of 1.8 W, beam energy of 8.6 MeV, and a beam current of 20 mA. After initial standardization, the irradiation of commodities was carried out. The doses employed were 0.06 kGy for onion, 0.10 kGy for potato, 0.25 kGy for rawa, and 8 kGy for spices. The desired dose was delivered by exposing the samples from the two opposite sides of the box. The microbial load in spice samples was determined immediately after the experiment, as well as after six months of storage at the ambient temperature (26±2 degC). Onion and potato samples were stored for a six months period both at ambient temperature and 15 degC for observing the effect of electron beam irradiation on sprouting in these commodities. Rawa samples were stored at ambient temperature for observing the effect of electron beam irradiation on insect disinfestation. The electron beam irradiation at the recommended doses was found to be as effective as gamma radiation in bringing down the microbial load of the tested spices to the desired level, disinfestations of rawa, and inhibition of sprouting in onion. In the case of potato even four-side irradiation of the product box did not inhibit the sprouting completely. This indicated the necessity of standardization of machine parameters for uniform dose distribution in the product box for each commodity. These lab-scale studies showed that electron beam could in principle be used for processing of various food products after standardizing the machine parameters and ensuring uniform dose distribution in the product. Use of this technology on commercial scale would need standardization on larger machines

  17. Budget Constraints Affect Male Rats’ Choices between Differently Priced Commodities

    Kalenscher, Tobias

    2015-01-01

    Demand theory can be applied to analyse how a human or animal consumer changes her selection of commodities within a certain budget in response to changes in price of those commodities. This change in consumption assessed over a range of prices is defined as demand elasticity. Previously, income-compensated and income-uncompensated price changes have been investigated using human and animal consumers, as demand theory predicts different elasticities for both conditions. However, in these studies, demand elasticity was only evaluated over the entirety of choices made from a budget. As compensating budgets changes the number of attainable commodities relative to uncompensated conditions, and thus the number of choices, it remained unclear whether budget compensation has a trivial effect on demand elasticity by simply sampling from a different total number of choices or has a direct effect on consumers’ sequential choice structure. If the budget context independently changes choices between commodities over and above price effects, this should become apparent when demand elasticity is assessed over choice sets of any reasonable size that are matched in choice opportunities between budget conditions. To gain more detailed insight in the sequential choice dynamics underlying differences in demand elasticity between budget conditions, we trained N=8 rat consumers to spend a daily budget by making a number of nosepokes to obtain two liquid commodities under different price regimes, in sessions with and without budget compensation. We confirmed that demand elasticity for both commodities differed between compensated and uncompensated budget conditions, also when the number of choices considered was matched, and showed that these elasticity differences emerge early in the sessions. These differences in demand elasticity were driven by a higher choice rate and an increased reselection bias for the preferred commodity in compensated compared to uncompensated budget

  18. World oil and agricultural commodity prices: Evidence from nonlinear causality

    International Nuclear Information System (INIS)

    The increasing co-movements between the world oil and agricultural commodity prices have renewed interest in determining price transmission from oil prices to those of agricultural commodities. This study extends the literature on the oil-agricultural commodity prices nexus, which particularly concentrates on nonlinear causal relationships between the world oil and three key agricultural commodity prices (corn, soybeans, and wheat). To this end, the linear causality approach of Toda-Yamamoto and the nonparametric causality method of Diks-Panchenko are applied to the weekly data spanning from 1994 to 2010. The linear causality analysis indicates that the oil prices and the agricultural commodity prices do not influence each other, which supports evidence on the neutrality hypothesis. In contrast, the nonlinear causality analysis shows that: (i) there are nonlinear feedbacks between the oil and the agricultural prices, and (ii) there is a persistent unidirectional nonlinear causality running from the oil prices to the corn and to the soybeans prices. The findings from the nonlinear causality analysis therefore provide clues for better understanding the recent dynamics of the agricultural commodity prices and some policy implications for policy makers, farmers, and global investors. This study also suggests the directions for future studies. - Research highlights: → This study determines the price transmission mechanisms between the world oil and three key agricultural commodity prices (corn, soybeans, and wheat). → The linear and nonlinear cointegration and causality methods are carried out. → The linear causality analysis supports evidence on the neutrality hypothesis. → The nonlinear causality analysis shows that there is a persistent unidirectional causality from the oil prices to the corn and to the soybeans prices.

In our view, however, commodity prices are essentially financial asset prices that are set in a forward-looking way, exactly like exchange rates. If both the exchange rate and the commodity prices are based on discounted future...... expectations, one should mostly observe contemporaneous correlations, not one-directional cross-predictability from one variable toward the other. Using three different data sets and various econometric techniques, we do find the contemporaneous correlations as predicted by the financial asset view of...

    We have studied here the self-organising features of the dynamics of a model market, where the agents `trade' for a single commodity with their money. The model market consists of fixed numbers of economic agents, money supply and commodity. We demonstrate that the model, apart from showing a self-organising behaviour, indicates a crucial role for the money supply in the market and also its self-organising behaviour is seen to be significantly affected when the money supply becomes less than ...

  11. ASSESSING THE GOVERNANCE FOR COMMODITY PRICE STABILIZATION - A RETROSPECTIVE LOOK

    Directory of Open Access Journals (Sweden)

    Pop Larisa Nicoleta

    2015-07-01

    Full Text Available The volatility of commodity prices has become once again a matter of profound and controversial debates for both political and academic spheres worldwide in the framework of the global economy severely distressed by the recent economic turbulences. Although commodity markets were already notorious for their price instability, the events the world economy experienced in the years 2000s offered new connotations to this phenomenon. In the first decade of this millennium, the commodity markets have struggled with high volatility, with prices reaching historical peaks just to crash dramatically some months later and very soon to restart their rise. The significant increase in volatility generated many debates about its triggering factors, the implications in terms of risk exposure of economic actors, but also the need for reconfiguring regulatory policy frameworks. The quest for the most appropriate means to deal with commodity price turbulences has known different stages over the years. Decision makers worldwide have sought alternatives, formulated and tested various mechanisms whose central aim was to mitigate price fluctuations. Governments formulate and implement consistent regulatory policies whose international coordination is a ‘sine qua non’ condition for stabilizing these markets. However, the turbulences on commodity markets often generate policy responses that sometimes exacerbate rather than mitigate the price instability. The purpose of this paper is to assess the subject of governance regarding commodity price stabilization, offering a retrospective look at the mechanisms implemented over the years, with a central focus on the International Commodity Agreements – instruments through which in the previous decades the producer and consumer governments worldwide pursued price stabilization for some key commodities like sugar, coffee, cocoa, tin and natural rubber. After analyzing the effectiveness of the International Agreements and

    This paper shows that the response of agricultural commodity prices in the U.S. related to fluctuations in oil prices in the international market may differ greatly depending on whether the increase is driven by demand or supply shocks in the crude oil market. In the long-run, around 2-7 percent of the variability in grains, oilseeds, and cotton prices can be attributed to shocks to aggregate demand for industrial commodities while none can be traced to oil supply shocks.

    2011-03-01

    It is widely known that commodity markets are not totally efficient. Long-range dependence is present, and thus the celebrated Brownian motion of prices can be considered only as a first approximation. In this work we analyzed the predictability in commodity markets by using a novel approach derived from Information Theory. The complexity-entropy causality plane has been recently shown to be a useful statistical tool to distinguish the stage of stock market development because differences between emergent and developed stock markets can be easily discriminated and visualized with this representation space [L. Zunino, M. Zanin, B.M. Tabak, D.G. Pérez, O.A. Rosso, Complexity-entropy causality plane: a useful approach to quantify the stock market inefficiency, Physica A 389 (2010) 1891-1901]. By estimating the permutation entropy and permutation statistical complexity of twenty basic commodity future markets over a period of around 20 years (1991.01.02-2009.09.01), we can define an associated ranking of efficiency. This ranking is quantifying the presence of patterns and hidden structures in these prime markets. Moreover, the temporal evolution of the commodities in the complexity-entropy causality plane allows us to identify periods of time where the underlying dynamics is more or less predictable.

The information is then entered onto computer manually, thus making the process a long and arduous one. With the development of the Haiti Commodity Tracker mobile app, we are able to make this commodity price data recording process more efficient. Officials may use this information for making inferences about the difference in commodity prices and for food distribution during critical time after natural disasters. This information can also be utilized by governments and aid agencies on their food assistance programs. Agronomists record the item prices from several sample sites in a marketplace and compare those results from other markets across the region. Due to limited connectivity in rural areas, data is first saved to the phone's database and then retransmitted to a central server via SMS messaging. The mobile app is currently being field tested by an international NGO providing agricultural aid and support in rural Haiti.

  5. Commodities and Switzerland: Development Policy Challenges and Policy Options

    Full Text Available EDITOR’S NOTEThis paper, written in December 2012, is a contribution to the ‘Policy Debate’ section of the International Development Policy. In this section, academics, policy makers and practitioners engage in a dialogue on global development challenges. Papers are copy-edited but not peer-reviewed. Instead, an initial thematic contribution is followed by critical comments and reactions from different stakeholders. This paper by Werner Thut is followed by reactions and analysis from a non-profit policy institute (Alexandra Gillies, Revenue Watch Institute, New York, ‘Crafting a Strategic Response to the Commodity-Development Conundrum’, a Southern scholar (Prof. Humberto Campodonico, Universidad Nacional Mayor de San Marcos, Lima ‘Going Beyond Transparency and Good Governance’ | ‘Más allá de la transparencia y una buena gobernanza’ and a representative of the trading sector (Stéphane Graber, Secretary General of Geneva Trading & Shipping Association – ‘Reassessing the Merchants’ Role in a Globalized Economy’.PAPER’S ABSTRACTSwitzerland is one of the world’s largest commodity trading hub. The author, senior policy adviser at the Swiss Agency for Development and Cooperation (SDC, reviews experiences and policy options related to commodity trading from a development policy perspective. While this sector has become of strategic importance to Switzerland’s economy, it also entails a number of risks. On the other hand, Swiss development cooperation efforts focus on several resource-rich countries, whose mineral and agricultural commodities are traded via Switzerland. How can Switzerland assist these countries to reap the benefits of their natural resource wealth? This paper looks at development policy aspects of commodity trading in relation to Swiss foreign and domestic policy. It examines ongoing policy debates in Switzerland and discusses development policy options.

  7. HESTIA Commodities Exchange Pallet and Sounding Rocket Test Stand

    Science.gov (United States)

    Chaparro, Javier

    2013-01-01

    During my Spring 2016 internship, my two major contributions were the design of the Commodities Exchange Pallet and the design of a test stand for a 100 pounds-thrust sounding rocket. The Commodities Exchange Pallet is a prototype developed for the Human Exploration Spacecraft Testbed for Integration and Advancement (HESTIA) program. Under the HESTIA initiative the Commodities Exchange Pallet was developed as a method for demonstrating multi-system integration thru the transportation of In-Situ Resource Utilization produced oxygen and water to a human habitat. Ultimately, this prototype's performance will allow for future evaluation of integration, which may lead to the development of a flight capable pallet for future deep-space exploration missions. For HESTIA, my main task was to design the Commodities Exchange Pallet system to be used for completing an integration demonstration. Under the guidance of my mentor, I designed, both, the structural frame and fluid delivery system for the commodities pallet. The fluid delivery system includes a liquid-oxygen to gaseous-oxygen system, a water delivery system, and a carbon-dioxide compressors system. The structural frame is designed to meet safety and transportation requirements, as well as the ability to interface with the ER division's Portable Utility Pallet. The commodities pallet structure also includes independent instrumentation oxygen/water panels for operation and system monitoring. My major accomplishments for the commodities exchange pallet were the completion of the fluid delivery systems and the structural frame designs. In addition, parts selection was completed in order to expedite construction of the prototype, scheduled to begin in May of 2016. Once the commodities pallet is assembled and tested it is expected to complete a fully integrated transfer demonstration with the ISRU unit and the Environmental Control and Life Support System test chamber in September of 2016. In addition to the development of

  8. Private Governance, Hegemonic Struggles, and Institutional Outcomes in the Transnational Cotton Commodity Chain

    Directory of Open Access Journals (Sweden)

    Amy Quark

    2015-08-01

    Full Text Available Transnational firms have rolled out new forms of private governance at the same time as the rise of new economic powerhouses like China has fomented growing inter-state tensions. This points to critical questions: how does inter-state competition shape private governance of transnational commodity chains and how does private governance shape inter-state rivalries? I explore these questions by tracing the construction and dissolution of sectoral hegemonic coalitions that govern commodity chains. Drawing on the case of cotton quality governance from 2000-2012, I argue that a coalition of the U.S. state and transnational merchants has reconstituted its sectoral hegemony to allow expanded accumulation and accommodate their main rival~China. The U.S. state created standards with Chinese characteristics, while transnational merchants made the authority structure of their institutions more inclusive. However, this reconstituted hegemony remains unstable. Facing continued regulatory competition from China, the U.S. state has constructed new forms of meta-governance that could facilitate a shift to Chinese-led sectoral hegemony but under U.S. oversight. Moreover, these sectoral hegemonic struggles compelled Western transnational merchants to fracture their long-standing relationship with the U.S. state in the hegemonic coalition in order to position their private institutions as geopolitically neutral and thus compatible with the hegemonic leadership of either the U.S. or Chinese states in the sector. By tracing struggles among coalitions of leading firms and states for hegemony over the institutions governing particular commodity chain sectors, we can shed light on possible trajectories within broader world-system level hegemonic struggles that at once constitute and are constituted by these sectoral dynamics.

  10. Limestone - A Crucial and Versatile Industrial Mineral Commodity

    Science.gov (United States)

    Bliss, James D.; Hayes, Timothy S.; Orris, Greta J.

    2008-01-01

    Limestone, as used by the minerals industry, is any rock composed mostly of calcium carbonate (CaCO3). Although limestone is common in many parts of the United States, it is critically absent from some. Limestone is used to produce Portland cement, as aggregate in concrete and asphalt, and in an enormous array of other products, making it a truly versatile commodity. Portland cement is essential to the building industry, but despite our Nation's abundance of limestone, there have been cement shortages in recent years. These have been caused in part by a need to find new areas suitable for quarrying operations. To help manage our Nation's resources of such essential mineral commodities, the U.S. Geological Survey (USGS) provides crucial data and scientific information to industry, policymakers, and the public.

  11. Network governance in electricity distribution: Public utility or commodity

    International Nuclear Information System (INIS)

    This paper addresses the question whether the operation and management of electricity distribution networks in a liberalized market environment evolves into a market driven commodity business or might be perceived as a genuine public utility task. A framework is developed to classify and compare different institutional arrangements according to the public utility model and the commodity model. These models are exemplified for the case of the Dutch electricity sector. It appears that the institutional organization of electricity distribution networks is at the crossroads of two very different institutional development paths. They develop towards commercial business if the system characteristics of the electricity sector remain basically unchanged to the traditional situation. If however innovative technological developments allow for a decentralization and decomposition of the electricity system, distribution networks might be operated as public utilities while other energy services are exploited commercially.

  14. The Role of Incompleteness in Commodity Futures Markets

    Directory of Open Access Journals (Sweden)

    Takashi eKanamura

    2015-10-01

    Full Text Available This paper proposes a convenience yield-based pricing for commodity futures, which embeds incompleteness of commodity futures markets in convenience yields. By using the pricing method, we conduct empirical analyses of the prices of WTI crude oil, heating oil, and natural gas futures traded on the NYMEX in order to assess the incompleteness of energy futures markets. We show that the fluctuation from the incompleteness is partly driven by the fluctuation from convenience yields. In addition, it is shown that the incompleteness of natural gas futures market is more highlighted than the incompleteness of WTI crude oil and heating oil futures markets. We apply the implied market price of risk from the NYMEX data to pricing an Asian call option written on WTI crude oil futures. Finally, we try to apply the market incompleteness analysis to the post-crisis periods after 2009.

  18. DYNAMICS AND NEW CHALLENGES IN THE GLOBAL COMMODITY MARKET

    Directory of Open Access Journals (Sweden)

    MARIA CARTAS

    2015-12-01

    Full Text Available Global economy and particularly the world production of goods depends to a large extent on the supply of raw materials, of resource inputs extracted from the environment as well as an easy access to them. Commodities play an important part in the growth of global production and in the world trade in goods and services. The access to raw materials is vital for sustaining the productive capacity of the economy and also for satisfying domestic demand for industrial goods. On the other side, increasing demand for commodities and the need for assuring a sustainable supply pose great challenges on the world economy. The issue of raw materials supply represents a high - priority theme in the political agenda of the European Union. The Raw Materials Initiative launched in 2008 by the European Commission is based on three main pillars: - to ensure the access to raw materials on world market at undistorted conditions; - to foster sustainable supply of raw materials from European sources; - to reduce the EU's consumption of primary raw materials. (EC, 2008. To this end, EC has started to take action in order to ensure access to resources and avoid supply shortages. A great deal of attention is being paid to the study of recent developments in the global and particular commodity markets, taking into consideration fundamental aspects as supply concentration, governance of producing countries, the pressure of demand and its impact on prices, material's substitutability, stressing the role of resource consumption efficiency, recycling and substitution of vital raw materials and thus providing policy makers and industry with reliable information on how to efficiently manage resource inputs. This paper is dealing with the main developments which occurred during the past decade or so in the global commodity market, a major driver of the world economy, with particular reference to selected key -markets - as: aluminium, copper, nickel; cotton; corn, meat - swine

  6. Predictive performance of the World Bank's commodity price projections

    OpenAIRE

    Warr, Peter G.

    1990-01-01

    The World Bank's commodity price projections are widely used for various planning purposes. Two aspects of the Bank's projections of relative prices are studied in this paper. The first is whether the forecasts make efficient use of the information available at the time the forecast is made. The second JS whether the forecasts predict future prices with greater accuracy than alternative forecasting methods. These matters are studied by comparing the World Bank's past price projections with th...

  7. Commodity Tax Harmonization with Public Goods - An Alternative Perspective

    OpenAIRE

    Lockwood, Ben

    1995-01-01

    This paper investigates whether it is possible to find Pareto-improving commodity tax reforms that harmonize taxes between two countries when governments supply public goods and thus have revenue requirements. To focus on the basic issues, we consider a Ricardian model of trade with elastic factor supply and two traded goods, and suppose that initial taxes are Nash equilibrium ones. This allows a complete characterization of the conditions under which Pareto-improving reforms exist using simp...

    We show that combining momentum and trend following strategies for individual commodity futures can lead to portfolios which offer attractive risk adjusted returns which are superior to simple momentum strategies; when we expose these returns to a wide array of sources of systematic risk we find that robust alpha survives. Experimenting with risk parity portfolio weightings has limited impact on our results though in particular is beneficial to long-short strategies; the marginal impact of ap...

  14. Optimal Nonlinear Pricing, Bundling Commodities and Contingent Services

    International Nuclear Information System (INIS)

    In this paper, we propose to analyze optimal nonlinear pricing when a firm offers in a bundle a commodity and a contingent service. The paper studies a mechanism design where all private information can be captured in a single scalar variable in a monopoly context. We show that to propose the package for commodity and service is less costly for the consumer, the firm has lower consumers' rent than the situation where it sells their good and contingent service under an independent pricing strategy. In fact, the possibility to use price discrimination via the supply of package is dominated by the fact that it is costly for the consumer to sign two contracts. Bundling energy and a contingent service is a profitable strategy for a energetician monopoly practising optimal nonlinear tariff. We show that the rates of the energy and the contingent service depend to the optional character of the contingent service and depend to the degree of complementarity between commodities and services.

  15. Commodity movement tracking (CMT) : bridging operations and commercial transactions

    International Nuclear Information System (INIS)

    Enbridge Pipelines Inc. (EPI) operates a network of interconnected pipelines that facilitate the transport of liquid fuels across North America, with operations centralized in Edmonton, Alberta. This paper addressed the issue of accurately tracking the location of commodities transported on EPI pipelines for billing and payment purposes. The role of integrated information systems in meeting the need for high quality information by customers and by EPI was also addressed. The paper presented the Commodity Movement Tracking (CMT) system that is central to achieving the desired accuracy of commercial and financial transactions. CMT tracks inventories and links products to commercial transactions across the pipeline. Batches are tracked from initial receipt to final delivery, incorporating CMT's operational checks and balances, reconciliation steps, process monitoring, and supervisory control and data acquisition (SCADA) systems data that contribute to inputs equaling outputs. Daily schedules are recorded into the CMT system as events, based on volumetric information derived from the SCADA system. Receipt and delivery events will be electronically recorded into CMT from field flow computers in the near future. CMT modeling considers changes within the line configuration, static pipe diameter changes, as well as packing and draining of the line fill resulting from pressure changes. This paper described the major functional activities of the overall business process, such as nominations, scheduling, commodity movement tracking, leak detection, electronic ticketing, SCADA, and oil accounting. 10 figs.

    Several factors are responsible for difficulties in describing the behaviour of commodity prices. Firstly, there are numerous different categories of commodities. Secondly, some categories overlap with other categories, while others indirectly compete in the market. Thirdly, although essentially commodity prices react to changes in economic conditions or exchange rates, to a large extent these prices depend on supply disturbances. However, in recent years commodity prices co-move, and researc...

    2016-04-01

    The global population currently stands at approximately 7 billion and is expected to increase to between 8.3 and 10.9 billion by 2050. To put this into perspective, today's global population is triple what it was in 1950. Commodities are required for healthy societies, for robust economies and to raise living standards in the developing world. With major increases the population particularly in nations with emerging economies, the demand for commodities such as water, energy and minerals will significantly increase during the next several decades. Among the concerns are clean and available freshwater, expanded energy sources from natural gas and nuclear to renewable energy, and emerging needs for specialty materials that are needed for advanced technology to expanded use of more conventional minerals for agriculture and commerce. The developing world may have the greatest need for these commodities and also be the source of many of them. At the conclusion of the International Year of Planet Earth, a small group was formed to assess the need for a major scientific effort in the geosciences. Under the auspices of the International Union of Geological Sciences (IUGS), the strategic initiatives group met and a broad initiative entitled 'Resourcing Future Generations' (RFG) that was designed to implement a scientific strategy to address the increasing demand for commodities over the next 25 years. The initiative focused on water resources, energy and minerals. The group felt strongly that the minerals component should be the initial emphasis and hoped that other global scientific organizations like IUGS would embrace the water and energy themes. Since this initial effort a number of workshops and presentations have been made including China, the International Geological Congress in Brisbane, the Davos Summit, Berlin, and Namibia amongst others. The strategic initiative planning group identifies 4 challenges to meeting future global mineral needs which are improved

    American scholar Grant Gilmore is deploring " the death of contract". Is it true? The author is trying to work out the "dilemma of individual cases" from three typical self-experienced eases, and analyze the "dilem- ma of integrity" from 30 cases concerning up to 1363 commodity houses purchase and sale, and segregate "legis- lation bewilderment" from the basic, implanting and invalid principles of the current legal system. Both legislation and reality bring problems and troubles of standard clause before us and "the death of contract" is not empty talk at all. How to revive the theory of contract that has survived more than a century and made wonders and prosper- ity but is now close to extinction? Nobody gives a satisfactory answer including "Resurrection of" Contract" wrote by a Japanese scholar. The paper intends to illustrate that jurisprudence principle serves as a premise as well as a foundation for the resurrection of contract and summarizes the nature and three characteristics of standard clause, namely inequality, non-negotiation and unspecific. It establishes such value orientations as freedom of contract and harmonious trade, free trade and nation's macro plan, fair trade and efficiency, contract justice and benefits harmony, basic substance and sustained development. Resurrection of contract calls for collective effort of legisla- tion, administration, and judicature. Standard clause has three prescriptive principles, namely establishment of standard and admission principle and elimination of invalid principle; perfection of investigation system and ille- gally prohibited system; establishment of some regulations concerning absolute and comparative invalidity, exemp- tion and investigation, rights estimation, the scope of obligation, and interpretation of clauses.%以美国学者格兰特·吉尔莫为代表的西方法学界哀叹“契约死亡”!果真如此吗?笔者以亲身经历的3个典型案例反映出“个案困境”,以30起1363件

    Introduction Logistics management information system for health commodities remained poorly implemented in most of developing countries. To assess the status of laboratory logistics management information system for HIV/AIDS and tuberculosis laboratory commodities in public health facilities in Addis Ababa. Methods A cross-sectional descriptive study was conducted from September 2010-January 2011 at selected public health facilities. A stratified random sampling method was used to include a total of 43 facilities which, were investigated through quantitative methods using structured questionnaires interviews. Focus group discussion with the designated supply chain managers and key informant interviews were conducted for the qualitative method. Results There exists a well-designed logistics system for laboratory commodities with trained pharmacy personnel, distributed standard LMIS formats and established inventory control procedures. However, majority of laboratory professionals were not trained in LMIS. Majority of the facilities (60.5%) were stocked out for at least one ART monitoring and TB laboratory reagents and the highest stock out rate was for chemistry reagents. Expired ART monitoring laboratory commodities were found in 25 (73.5%) of facilities. Fifty percent (50%) of the assessed hospitals and 54% of health centers were currently using stock/bin cards for all HIV/AIDS and TB laboratory commodities in main pharmacy store, among these only 25% and 20.8% of them were updated with accurate information matching with the physical count done at the time of visit for hospitals and health centers respectively. Conclusion Even though there exists a well designed laboratory LMIS, keeping quality stock/bin cards and LMIS reports were very low. Key ART monitoring laboratory commodities were stock out at many facilities at the day of visit and during the past six months. Based on findings, training of laboratory personnel's managing laboratory commodities and keeping

  2. An analysis on types of strategic commodities and technologies

    International Nuclear Information System (INIS)

    In the study, Reconsideration of classification cases was carried out and a database was built based on Information of classification requests as features which are necessary for data mining. In this study, two main features of classified documents were organized systematically to apply data mining skills. It will be helpful to discover association rules between documents and to classify documents as they are key factors of strategic commodity classification. In addition, the classification scheme presented in the study helps step-by-step search by adding the auxiliary search criteria. The international community strengthened the export control regime. Accordingly, Korea also needs to fully comply with the export control obligations. Despite International export control regimes are strengthened, the current system to control exports of strategic commodities relies on limited human resource and experience to the situation. Especially, exports of nuclear power plants are related to one thousand kinds more material. Thus, the burden of the government, relevant institutes and enterprises has increased a lot. It is necessary to enhance the ease and efficiency of export control business processes in order to cope with such export control issues. NSSC operates the NEPS system for export control of nuclear items. Technical reviewers can search past cases of strategic commodity classification on NEPS system. However, searching function of NEPS system has limitations because exports to UAE and Jordan increased sharply, but characteristics of classification requests are not systematized. To provide more efficient ways to their decisions, development of the advanced export control system, IXCS (Intelligent eXport Control System) is considered. IXCS will adopt various methods including data mining. Data mining is the computational process of discovering patterns in large data sets. It is an efficient way to find out hidden consideration patterns. However, it needs many kinds of

    Visualization of protein structures using stereoscopic systems is frequently needed by structural biologists working to understand a protein's structure-function relationships. Often several scientists are working as a team and need simultaneous interaction with each other and the graphics representations. Most existing molecular visualization tools support single-user tasks, which are not suitable for a collaborative group. Expensive caves, domes or geowalls have been developed, but the availability and low cost of high-definition televisions (HDTVs) and game controllers in the commodity entertainment market provide an economically attractive option to achieve a collaborative environment. This paper describes a low-cost environment, using standard consumer game controllers and commercially available stereoscopic HDTV monitors with appropriate signal converters for structural biology collaborations employing existing binary distributions of commonly used software packages like Coot, PyMOL, Chimera, VMD, O, Olex2 and others.

    We describe a new 512-CPU Beowulf cluster with Teraflop performance dedicated to problems in computational astrophysics. The cluster incorporates a cubic network topology based on inexpensive commodity 24-port gigabit switches and point to point connections through the second gigabit port on each Linux server. This configuration has network performance competitive with more expensive cluster configurations and is scaleable to much larger systems using other network topologies. Networking represents only about 9% of our total system cost of USD$561K. The standard Top 500 HPL Linpack benchmark rating is 1.202 Teraflops on 512 CPUs so computing costs by this measure are $0.47/Megaflop. We also describe 4 different astrophysical applications using complex parallel algorithms for studying large-scale structure formation, galaxy dynamics, magnetohydrodynamic flows onto blackholes and planet formation currently running on the cluster and achieving high parallel performance. The MHD code achieved a sustained speed of...

  5. Processing of food and agricultural commodities with electron beam from microtron

    International Nuclear Information System (INIS)

    A microtron machine source installed by the Centre for Advanced Technology (CAT), Indore, at Mangalore University, was used to study effects of irradiation on onion, potato, rava, and spices. The microbial load in spice samples was determined immediately after the experiment, as well as after six months of storage at the ambient temperature (26±2 deg C). Onion and potato samples were stored for a six months period both at ambient temperature and 15 deg C for observing the effect of electron beam irradiation on sprouting in these commodities. Rawa samples were stored at ambient temperature for observing the effect of electron beam irradiation on insect disinfestation. The results are discussed in detail in this paper. These lab-scale studies showed that electron beam could in principle be used for processing of various food products after standardizing the machine parameters and ensuring uniform dose distribution in the product.

    Commodity prices are expected to remain weak for the remainder of 2014 and, perhaps through much of 2015. Crude oil has seen one of the sharpest declines, down more than 20 percent to $83/barrel (bbl) on October 15 from this year’s high of $108/bbl in mid-June. Agricultural prices have weakened as well, down 6 percent since June. Metal prices remained relatively stable, from the sharp declines seen in 2011. A slowdown in the Euro area and emerging economies, a strong US dollar, increased oil ...

  15. The changing dynamics between biofuels and commodity markets

    International Nuclear Information System (INIS)

    The recent development of the biofuel industries coincides with significant increases in prices of basic commodities such as food and feed. Against popular perception, it appears that there is not a straightforward causal relationship between the two; there are a number of factors that determine the level and strength of the impact of the biofuels sector on other commodities. For the case of markets of agricultural raw material these factors include the amount of feedstock claimed by the biofuels industry, its relative purchasing power, the responsiveness of the agricultural sector to price incentives and availability of substitutes. For consumer food markets we must additionally consider the relative share of agricultural input costs in the retail food price and the demand elasticity. Based on the analysis of these factors and estimates of other studies that attempted to quantify the price impacts of biofuels on crop prices, we conclude that the impact of biofuels is relatively small, especially when compared with other causes that triggered the recent price increases. We end the paper with a recommendation for future efforts in curbing food price inflations while keeping ambitious biofuel targets and suggest a shift in focus of the debate around the social costs of biofuels

  16. Survey of Alternative Feedstocks for Commodity Chemical Manufacturing

    Energy Technology Data Exchange (ETDEWEB)

    McFarlane, Joanna [ORNL; Robinson, Sharon M [ORNL

    2008-02-01

    The current high prices for petroleum and natural gas have spurred the chemical industry to examine alternative feedstocks for the production of commodity chemicals. High feedstock prices have driven methanol and ammonia production offshore. The U.S. Chemical Industry is the largest user of natural gas in the country. Over the last 30 years, alternatives to conventional petroleum and natural gas feedstocks have been developed, but have limited, if any, commercial implementation in the United States. Alternative feedstocks under consideration include coal from unconventional processing technologies, such as gasification and liquefaction, novel resources such as biomass, stranded natural gas from unconventional reserves, and heavy oil from tar sands or oil shale. These feedstock sources have been evaluated with respect to the feasibility and readiness for production of the highest volume commodity chemicals in the United States. Sources of organic compounds, such as ethanol from sugar fermentation and bitumen-derived heavy crude are now being primarily exploited for fuels, rather than for chemical feedstocks. Overall, government-sponsored research into the use of alternatives to petroleum feedstocks focuses on use for power and transportation fuels rather than for chemical feedstocks. Research is needed to reduce cost and technical risk. Use of alternative feedstocks is more common outside the United States R&D efforts are needed to make these processes more efficient and less risky before becoming more common domestically. The status of alternative feedstock technology is summarized.

In this regard, especially updated become theoretical developments in the field of commodity flows on an international caliber. The article analyzes the interpretations of scholars of various economic scientists of the concept of "commodity flow" explores theoretical approaches for building goods distribution management at the level of international companies. Particular attention is paid to the risks assessment in the process of changing the output of trading companies at the international level. The role of the international net brokers is determining in the logistic system of goods distribution. The front most methods of risk management of major trade companies are highly investigating. The authors conclude that in entering the international markets trading companies are often unable to develop an effective risk management system due to lack of information, difficulty adapting to the new business environment. Many aspects of international goods distribution require further study with the aim of improving the efficiency of inventory management and logistics network trade flows of businesses

  19. Balancing Acts: Culture as Commodity Among Business Consultants

    Directory of Open Access Journals (Sweden)

    Elias Mellander

    2013-09-01

    Full Text Available In this article the authors intend to analyze how the concept of culture is packaged, sold and delivered as a commodity. It is based on an ethnographic study of a Swedish consultancy in the field of cross-cultural communication and the relationship between the company and its clients. The clients were primarily foreign executives working in Sweden or Swedish expatriates, preparing for life abroad. The significance of culture-as-commodity will be explored from the perspective of the company as well as its clients in order to shed light on how the concept of culture can be communicated and what happens to it in the process. The study shows how the company combines theoretical perspectives from anthropology and intercultural communication with the aim to deliver a complex yet accessible understanding of culture to its clients. The analysis shows that these perspectives both clash and synergize, creating contradictions as well as turning culture into an accessible and useful tool for clients. The authors argue that researchers in the field of applied cultural analysis can learn from the example put forth by the balancing act between these two perspectives on culture performed by the company. The authors conclude that although the commodification process reduces and simplifies the meaning(s of culture, the company still manages to put culture on the agenda, demonstrating to its clients how, why, and in what ways it matters to them.

  20. Response of tropical horticultural commodities to insect disinfestation treatments

    International Nuclear Information System (INIS)

    There is a need to develop effective, non-damaging, non-polluting, non-carcinogenic procedures for insect disinfestation and disease control in fresh horticultural products. The loss of ethylene dibromide as a fumigant and the uncertainties of other fumigants, has meant that alternatives are needed. The most likely possibilities include irradiation, heat, cold and controlled atmospheres. Irradiation doses required for sterilization of insects cause only minor physiological changes, while controlled atmospheres appear to require longer periods of exposure than the postharvest life of most tropical fruit. The sensitivity of tropical commodities to temperatures less than 10°C makes cold treatments inappropriate for most tropical commodities. Heat treatments seem to be most promising. For papaya, the requirement is that the fruit core temperature reach 47.2°C, this can occasionally disrupt fruit ripening. The sensitivity to heat is modified by seasonal, variety and rate of heating factors. The sensitivity can be related to the heat shock response and the presence of heat shock proteins. (author)

  2. Analysis of physical flows in primary commodity trade. A case study in China

    International Nuclear Information System (INIS)

    How globalization and international trade affect sustainable development and environment has attracted worldwide attention. Associated with the import and export of primary commodities, ecologically important materials have been exchanged among regions and countries. China, having the largest population in the world and the highest economic growth rate in last decades, may have an important influence on global sustainable development through the trade of primary commodities. Using the data from Almanac of China's Foreign Economic Relations and Trade, we analyzed material flows in the trade of primary commodity in China from 1950 to 2001. Our analysis shows that: (1) China has turned from a net exporter of primary commodities to a net importer; (2) minerals and fuels have been the major imports of primary commodities since 1992, just as well as foods and minerals did in 1980s; (3) most of the net imported primary commodities come from Oceania, Africa and Latin America.

    The human capacity for altering the water cycle has been well documented and given the expected change due to population, income growth, biofuels, climate, and associated land use change, there remains great uncertainty in both the degree of increased pressure on land and water resources and in our ability to adapt to these changes. Alleviating regional shortages in water supply can be carried out in a spatial hierarchy through i) direct trade of water between all regions, ii) development of infrastructure to improve water availability within regions (e.g. impounding rivers), iii) via inter-basin hydrological transfer between neighboring regions and, iv) via virtual water trade. These adaptation strategies can be managed via market trade in water and commodities to identify those strategies most likely to be adopted. This work combines the physically-based University of New Hampshire Water Balance Model (WBM) with the macro-scale Purdue University Simplified International Model of agricultural Prices Land use and the Environment (SIMPLE) to explore the interaction of supply and demand for fresh water globally. In this work we use a newly developed grid cell-based version of SIMPLE to achieve a more direct connection between the two modeling paradigms of physically-based models with optimization-driven approaches characteristic of economic models. We explore questions related to the global and regional impact of water scarcity and water surplus on the ability of regions to adapt to future change. Allowing for a variety of adaptation strategies such as direct trade of water and expanding the built water infrastructure, as well as indirect trade in commodities, will reduce overall global water stress and, in some regions, significantly reduce their vulnerability to these future changes.

    It has been shown in new trade theory that trade taxes/subsidies may be optimal in the case of oligopolistic markets. This result has relevance for international commodity markets because there is growing evidence of imperfect competition in commodity trade. However, it has also been demonstrated that the optimal strategic trade policy depends on whether the market is distinguished by Bertrand (price) or Cournot (quantity) competition. We argue that commodity markets may be characterised by e...

  10. Reconciling biofuels, sustainability and commodities demand. Pitfalls and policy options

    International Nuclear Information System (INIS)

    Increasing fossil fuel prices, energy security considerations and environmental concerns, particularly concerning climate change, have motivated countries to explore alternative energy sources including biofuels. Global demand for biofuels has been rising rapidly due to biofuel support policies established in many countries. However, proposed strong links between biofuels demand and recent years' high food commodity prices, and notions that increasing biofuels production might bring about serious negative environmental impacts, in particularly associated with the land use change to biofuel crops, have shifted public enthusiasm about biofuels. In this context, the ELOBIO project aims at shedding further light to these aspects of biofuel expansion by collecting and reviewing the available data, and also developing strategies to decrease negative effects of biofuels while enabling their positive contribution to climate change, security of supply and rural development. ELOBIO considers aspects associated with both 1st and 2nd generation biofuels, hence analyses effects on both agricultural commodity markets and lignocellulosic markets. This project, funded by the Intelligent Energy Europe programme, consists of a review of current experiences with biofuels and other renewable energy policies and their impacts on other markets, iterative stakeholder-supported development of low-disturbing biofuels policies, model supported assessment of these policies' impacts on food, feed and lignocellulosic markets, and finally an assessment of the effects of selected optimal policies on biofuels costs and potentials. Results of the ELOBIO study show that rapid biofuel deployment without careful monitoring of consequences and implementation of mitigating measures risks leading to negative consequences. Implementing ambitious global biofuel targets for 2020, based on current 1st generation technologies, can push international agricultural commodity prices upwards and increase crop

  13. Boom or bust : developing countries' rough ride on the commodity price rollercoaster

    International Nuclear Information System (INIS)

    Current high commodity prices are driven by strong demand from the emerging economies of China and India in addition to high consumption in the United States. Many developing countries are experiencing massive windfall revenues from high commodity prices. However, commodity prices are highly volatile in the short term, and can vary as much as 50 per cent in a single year. While developed country producers are supported by subsidies and social safety nets, developing countries and smallholder producers feel the extent of commodity price volatility more directly. Many developing countries are becoming locked into the production and export of primary commodities whose volatile prices are declining over the long term, and over which they have very little control. Price volatility makes sound fiscal planning difficult for both countries and producers. Price booms and busts also drive social inequalities, livelihood inequalities, and corruption. Price swings can cause conflict over valuable land and resources, and does not create incentives for sound environmental stewardship. This paper described the impacts of commodity price volatility in developing countries with the aim of promoting discussion about what can be done to help stabilize revenues for countries as well as producers. Price trends and their importance were reviewed, and the theoretical benefits of liberalized commodity markets were examined. Previous attempts to stabilize commodity prices were reviewed. It was concluded that the best long-term solution to the commodity price problem is economic diversification. Recommendations for promoting economic diversification were provided. 43 refs., 1 tab., 2 figs

    2011-11-01

    Developing uniformly formatted, densified feedstock from lignocellulosic biomass is of interest to achieve consistent physical properties like size and shape, bulk and unit density, and durability, which significantly influence storage, transportation and handling characteristics, and, by extension, feedstock cost and quality. A variety of densification systems are considered for producing a uniform format feedstock commodity for bioenergy applications, including (a) baler, (b) pellet mill, (c) cuber, (d) screw extruder, (e) briquette press, (f) roller press, (g) tablet press, and (g) agglomerator. Each of these systems has varying impacts on feedstock chemical and physical properties, and energy consumption. This review discusses the suitability of these densification systems for biomass feedstocks and the impact these systems have on specific energy consumption and end product quality. For example, a briquette press is more flexible in terms of feedstock variables where higher moisture content and larger particles are acceptable for making good quality briquettes; or among different densification systems, a screw press consumes the most energy because it not only compresses but also shears and mixes the material. Pretreatment options like preheating, grinding, steam explosion, torrefaction, and ammonia fiber explosion (AFEX) can also help to reduce specific energy consumption during densification and improve binding characteristics. Binding behavior can also be improved by adding natural binders, such as proteins, or commercial binders, such as lignosulphonates. The quality of the densified biomass for both domestic and international markets is evaluated using PFI (United States Standard) or CEN (European Standard).

  17. Effects of Regulation and Technology on End Uses of Nonfuel Mineral Commodities in the United States

    Matos, Grecia R.

    2007-01-01

    The regulatory system and advancement of technologies have shaped the end-use patterns of nonfuel minerals used in the United States. These factors affected the quantities and types of materials used by society. Environmental concerns and awareness of possible negative effects on public health prompted numerous regulations that have dramatically altered the use of commodities like arsenic, asbestos, lead, and mercury. While the selected commodities represent only a small portion of overall U.S. materials use, they have the potential for harmful effects on human health or the environment, which other commodities, like construction aggregates, do not normally have. The advancement of technology allowed for new uses of mineral materials in products like high-performance computers, telecommunications equipment, plasma and liquid-crystal display televisions and computer monitors, mobile telephones, and electronic devices, which have become mainstream products. These technologies altered the end-use pattern of mineral commodities like gallium, germanium, indium, and strontium. Human ingenuity and people?s demand for different and creative services increase the demand for new materials and industries while shifting the pattern of use of mineral commodities. The mineral commodities? end-use data are critical for the understanding of the magnitude and character of these flows, assessing their impact on the environment, and providing an early warning of potential problems in waste management of products containing these commodities. The knowledge of final disposition of the mineral commodity allows better decisions as to how regulation should be tailored.

    2012-11-01

    Full Text Available With the current pace of growth, India would emerge as a major player in the international market in terms of commodity consumption, production and trade. Going by trade volume and also the possibly as an identifiable influence on the price making process on the essential commodities, the futures and spot markets have shown major variations. Increased volatility in asset prices has been a major reason behind the integration of domestic financial markets with the international financial sector accentuating the demand for the trading in the derivative market. Though organized commodity trading has been in from the nineteenth century in India, the commodity derivative markets in the new form with nationwide electronic trading and access have opened the gates for speculators, hedgers and other market participants to capitalize on the development. The robust growth of the commodity markets can be observed in terms of number of commodities trade volumes and growing number of both the market participants and the commodity exchanges. Liquidity booms reflected by loose monetary policy are responsible for major surge in commodity prices globally in addition to direct tangible impacts of oil prices especially in developing countries with heavy oil imports like India. Futures markets are created to fulfill genuine desires economic functions of hedging and price discovery. But, enormous futures trading observed on the commodity exchanges have raised a host of issues like inflation guided by the fuelling principle implying the direct relationship between volatility and inflation. Huge price volatility in futures segment on the commodity exchanges has therefore raised concerns relating to the market efficiencies, infrastructure and knowledge and also their consequential impact on cash markets. The demand and supply side of the commodity price mechanism is traditionally governed by numerous factors including the climatic conditions, availability of critical

  7. Using commodity-indexed financing to fund OPEC/Alaska's development projects

    International Nuclear Information System (INIS)

    An impediment to the process of economic diversification in OPEC and Alaska is the lack of favourable access to local and international capital markets to finance development projects, particularly mineral resource development. This paper highlights the importance of commodity-indexed bonds, including oil- and gold- indexed bonds, as a financing alternative to supplement the supply shortage of loanable funds from conventional, local and international commercial banks. The indexation concept is discussed, features of different bonds issued to date are contrasted and the benefits and risks for borrowers and investors are highlighted. An analysis is made of the experience of OPEC and Alaska in using commodity-indexed bonds and the feasibility of Alaska and some OPEC countries entering into commodity-linked-financed joint ventures is examined. Future prospects for commodity-linked bonds are explored. Not withstanding the fact that the immediate market timing is unfavourable, the long-term benefits of commodity-indexed securities are recognized. (U.K.)

  8. Construction Method of Display Proposal for Commodities in Sales Promotion by Genetic Algorithm

    Science.gov (United States)

    Yumoto, Masaki

    In a sales promotion task, wholesaler prepares and presents the display proposal for commodities in order to negotiate with retailer's buyers what commodities they should sell. For automating the sales promotion tasks, the proposal has to be constructed according to the target retailer's buyer. However, it is difficult to construct the proposal suitable for the target retail store because of too much combination of commodities. This paper proposes a construction method by Genetic algorithm (GA). The proposed method represents initial display proposals for commodities with genes, improve ones with the evaluation value by GA, and rearrange one with the highest evaluation value according to the classification of commodity. Through practical experiment, we can confirm that display proposal by the proposed method is similar with the one constructed by a wholesaler.

    This crosswalk is based on the premise that there is a connection between the way mineral commodities are used and how this use is reflected in the economy. Raw mineral commodities are the basic materials from which goods, finished products, or intermediate materials are manufactured or made. Mineral commodities are vital to the development of the U.S. economy and they impact nearly every industrial segment of the economy, representing 12.2 percent of the U.S. gross domestic product (GDP) in 2010 (U.S. Bureau of Economic Analysis, 2014). In an effort to better understand the distribution of mineral commodities in the economy, the U.S. Geological Survey (USGS) attempts to link the end uses of mineral commodities to the corresponding North American Industry Classification System (NAICS) codes.

  10. The Effect of Monetary Policy on Commodity Prices: Disentangling the Evidence for Individual Prices

    2014-01-01

    Full Text Available We study the effect of monetary policy shocks on commodity prices. While most of the literature has found that expansionary shocks have a positive effect on aggregate price indices, we study the effect on individual prices of a sample of four commodities. This set of commodity prices is essential to understand the dynamics of the balance of payments in Colombia. The analysis is based on structural VAR models; we identify monetary policy shocks following Kim (1999, 2003 upon quarterly data for commodity prices and their fundamentals for the period from 1980q1 to 2010q3. Our results show that commodity prices overshoot their long run equilibrium in response to a contractionary shock in the US monetary policy and, in contrast with literature, the response of the individual prices considered is stronger than what has been found in aggregate indices. Additionally, it is found that the monetary policy explains a substantial share of the fluctuations in prices.

  11. INTRODUCING SIMPLEX MASS BALANCING METHOD FOR MULTI-COMMODITY FLOW NETWORK WITH A SEPARATOR

    Directory of Open Access Journals (Sweden)

    Ziauddin Ursani

    2015-11-01

    Full Text Available Maximization of flow through the network has remained core issue in the field of optimization. In this paper a new advanced network problem is introduced, i.e., a multi-commodity network with a separator. This network consists of several sub-networks linked through a commodity separator. The objective is to maximize the flow of the commodity of interest from the commodity mixture at the output of the commodity separator, while observing the capacity constraints of all sub-networks. Such networks are present in Oil and Gas development fields. Such networks are also conceptual representation of material flows of many other manufacturing systems. In this paper an algorithm is developed for maximization of flow in these networks. Maximization of flow in such networks has direct practical relevance and industrial application. The developed algorithm brings together two distinct branches of computer science i.e., graph theory and linear programming to solve the problem.

  12. Modelling volatility recurrence intervals in the Chinese commodity futures market

    Zhou, Weijie; Wang, Zhengxin; Guo, Haiming

    2016-09-01

    The law of extreme event occurrence attracts much research. The volatility recurrence intervals of Chinese commodity futures market prices are studied: the results show that the probability distributions of the scaled volatility recurrence intervals have a uniform scaling curve for different thresholds q. So we can deduce the probability distribution of extreme events from normal events. The tail of a scaling curve can be well fitted by a Weibull form, which is significance-tested by KS measures. Both short-term and long-term memories are present in the recurrence intervals with different thresholds q, which denotes that the recurrence intervals can be predicted. In addition, similar to volatility, volatility recurrence intervals also have clustering features. Through Monte Carlo simulation, we artificially synthesise ARMA, GARCH-class sequences similar to the original data, and find out the reason behind the clustering. The larger the parameter d of the FIGARCH model, the stronger the clustering effect is. Finally, we use the Fractionally Integrated Autoregressive Conditional Duration model (FIACD) to analyse the recurrence interval characteristics. The results indicated that the FIACD model may provide a method to analyse volatility recurrence intervals.

  14. Haptic Rendering in Interactive Applications Developed with Commodity Physics Engine

    Directory of Open Access Journals (Sweden)

    Kup-Sze Choi

    2011-04-01

    Full Text Available Availability of commodity physics engines such as PhysX’s nVidia has significantly reduced the effort required for developing interactive applications concerning the simulation of the physical world. However, it becomes a problem when force feedback is needed since the addition of haptic rendering into these applications is non-trivial. The issues include the high haptic update rate and the inaccessibility of force data in the physics engine. In the paper, we tackle the first issue by mediating the update-rate disparity between haptic rendering and other processes by data buffering, and the second issue by calculating the force feedback indirectly using the engine’s collision geometry data. The major benefit of these techniques is that they enable a homogeneous development environment where the same engine can be used for both the physics and haptic simulation. Furthermore, integration of force feedback into physics-engine based applications would not introduce significant changes into developer’s codebase. The proposed techniques have potential to streamline the development of demanding applications such as virtual surgical simulation and immersive computer gaming.

  15. Service Availability Monitoring Framework Based On Commodity Software

    International Nuclear Information System (INIS)

    The Worldwide LHC Computing Grid (WLCG) infrastructure continuously operates thousands of grid services scattered around hundreds of sites. Participating sites are organized in regions and support several virtual organizations, thus creating a very complex and heterogeneous environment. The Service Availability Monitoring (SAM) framework is responsible for the monitoring of this infrastructure. SAM is a complete monitoring framework for grid services and grid operational tools. Its current implementation tailored for a decentralized operation replaces the old SAM system which is now being decommissioned from production. SAM provides functionality for submission of monitoring probes, gathering of probes results, processing of monitoring data, and retrieval of monitoring data in terms of service status, availability, and reliability. In this paper we present the SAM framework. We motivate the need from moving from the old SAM to a new monitoring infrastructure deployed and managed in a distributed environment and explain how SAM exploits and builds on top of commodity software, such as Nagios and Apache ActiveMQ, to provide a reliable and scalable system. We also present the SAM architecture by highlighting the adopted technologies and how the different SAM components deliver a complete monitoring framework.

  16. Commodity hardware and open source solutions in FTU data management

    International Nuclear Information System (INIS)

    Frascati Tokamak Upgrade (FTU) data management system underwent several developments in the last year, mainly due to the availability of huge amount of open source software and cheap commodity hardware. First of all, we replaced the old and expensive four SUN/SOLARIS servers running AFS (Andrew File System) fusione.it cell with three SuperServer Supermicro SC-742. Secondly Linux 2.4 OS has been installed on our new cell servers and OpenAFS 1.2.8 open source distributed file system has replaced the commercial IBM/Transarc AFS. A pioneering solution - SGI's XFS file system for Linux - has been adopted to format one terabyte of FTU storage system on which the AFS volumes are based. Benchmark tests have shown the good performances of XFS compared to the classical ext3 Linux file system. Third, the data access software has been ported to Linux, together with the interfaces to Matlab and IDL, as well as the locally developed data display utility, SHOX. Finally a new Object-Oriented Data Model (OODM) has been developed for FTU shots data to build and maintain a FTU data warehouse (DW). FTU OODM has been developed using ROOT, an object oriented data analysis framework well-known in high energy physics. Since large volumes of data are involved, a parallel data extraction process, developed in the ROOT framework, has been implemented taking advantage of the AFS distributed environment of FTU computing system

  17. Residues resulting from fumigation of food commodities with methyl bromide

    International Nuclear Information System (INIS)

    An investigation was undertaken to determine the nature and significance of residues remaining in methyl bromide-fumigated commodities using radiotracer techniques (14C-methyl bromide). Experiments with corn showed that the germ part of the kernel contained nearly half of the total 14C-residue remaining in the seed. Also preliminary tests with granny smith apples revealed that considerable residue may remain in seeds of treated apples with less in skin and the least in the fleshy pulp. In fumigated corn, fractionation revealed that radioactive residues were distributed throughout albumins, globulins, Zein 1, Zein 2 and glutelin with a large part in the aqueous extract (amino acids). Further investigation emphasized the characterization of volatile substances resulting from alkali treatment. It was found that methyl bromide readily methylated methionine and this constitutes a major site of methylation. A component of the volatile fraction was dimethyl sulfoxide, probably a product of oxidation of dimethyl sulphide. Work is in progress to determine whether methyl bromide will methylate purine and pyrimidine components. (author)

    Gellrich, A; Wegner, P; Wittig, H; Hasenbusch, M; Jansen, K

    2003-01-01

    Lattice Gauge Theory is an integral part of particle physics that requires high performance computing in the multi-Tflops regime. These requirements are motivated by the rich research program and the physics milestones to be reached by the lattice community. Over the last years the enormous gains in processor performance, memory bandwidth, and external I/O bandwidth for parallel applications have made commodity clusters exploiting PCs or workstations also suitable for large Lattice Gauge Theory applications. For more than one year two clusters have been operated at the two DESY sites in Hamburg and Zeuthen, consisting of 32 resp. 16 dual-CPU PCs, equipped with Intel Pentium 4 Xeon processors. Interconnection of the nodes is done by way of Myrinet. Linux was chosen as the operating system. In the course of the projects benchmark programs for architectural studies were developed. The performance of the Wilson-Dirac Operator (also in an even-odd preconditioned version) as the inner loop of the Lattice QCD (LQCD)...

    2014-01-01

    Hardware and software design and system integration for an intelligent precision jigging robot (IPJR), which allows high precision assembly using commodity parts and low-precision bonding, is described. Preliminary 2D experiments that are motivated by the problem of assembling space telescope optical benches and very large manipulators on orbit using inexpensive, stock hardware and low-precision welding are also described. An IPJR is a robot that acts as the precise "jigging", holding parts of a local structure assembly site in place, while an external low precision assembly agent cuts and welds members. The prototype presented in this paper allows an assembly agent (for this prototype, a human using only low precision tools), to assemble a 2D truss made of wooden dowels to a precision on the order of millimeters over a span on the order of meters. The analysis of the assembly error and the results of building a square structure and a ring structure are discussed. Options for future work, to extend the IPJR paradigm to building in 3D structures at micron precision are also summarized.

  1. Lattice QCD calculations on commodity clusters at DESY

    International Nuclear Information System (INIS)

    Lattice Gauge Theory is an integral part of particle physics that requires high performance computing in the multi-Tflops regime. These requirements are motivated by the rich research program and the physics milestones to be reached by the lattice community. Over the last years the enormous gains in processor performance, memory bandwidth, and external I/O bandwidth for parallel applications have made commodity clusters exploiting PCs or workstations also suitable for large Lattice Gauge Theory applications. For more than one year two clusters have been operated at the two DESY sites in Hamburg and Zeuthen, consisting of 32 resp. 16 dual-CPU PCs, equipped with Intel Pentium 4 Xeon processors. Interconnection of the nodes is done by way of Myrinet. Linux was chosen as the operating system. In the course of the projects benchmark programs for architectural studies were developed. The performance of the Wilson-Dirac Operator (also in an even-odd preconditioned version) as the inner loop of the Lattice QCD (LQCD) algorithms plays the most important role in classifying the hardware basis to be used. Using the SIMD streaming extensions (SSE/SSE2) on Intel's Pentium 4 Xeon CPUs give promising results for both the single CPU and the parallel version. The parallel performance, in addition to the CPU power and the memory throughput, is nevertheless strongly influenced by the behavior of hardware components like the PC chip-set and the communication interfaces. The paper starts by giving a short explanation about the physics background and the motivation for using PC clusters for Lattice QCD. Subsequently, the concept, implementation, and operating experiences of the two clusters are discussed. Finally, the paper presents benchmark results and discusses comparisons to systems with different hardware components including Myrinet-, GigaBit-Ethernet-, and Infiniband-based interconnects.

    2014-01-01

    Regolith is present on most planetary surfaces such as Earth's moon, Mars, and Asteroids. If human crews and robotic machinery are to operate on these regolith covered surfaces, they must face the consequences of interacting with regolith fines which consist of particles below 100 microns in diameter down to as small as submicron scale particles. Such fine dust will intrude into mechanisms and interfaces causing a variety of problems such as contamination of clean fluid lines, jamming of mechanisms and damaging connector seals and couplings. Since multiple elements must be assembled in space for system level functionality, it will be inevitable that interfaces will be necessary for structural connections, and to pass commodities such as cryogenic liquid propellants, purge and buffer gases, water, breathing air, pressurizing gases, heat exchange fluids, power and data. When fine regolith dust is present in the environment it can be lofted into interfaces where it can compromise the utility of the interface by preventing the connections from being successfully mated, or by inducing fluid leaks or degradation of power and data transmission. A dust tolerant, hand held "quick-disconnect" cryogenic fluids connector housing has been developed at NASA KSC which can be used by astronaut crews to connect flex lines that will transfer propellants and other useful fluids to the end user. In addition, a dust tolerant, automated, cryogenic fluid, multiple connector, power and data interface mechanism prototype has been developed, fabricated and demonstrated by NASA at Kennedy Space Center (KSC). The design and operation of these prototypes are explained and discussed.

    The Computational Plant or Cplant is a commodity-based distributed-memory supercomputer under development at Sandia National Laboratories. Distributed-memory supercomputers run many parallel programs simultaneously. Users submit their programs to a job queue. When a job is scheduled to run, it is assigned to a set of available processors. Job runtime depends not only on the number of processors but also on the particular set of processors assigned to it. Jobs should be allocated to localized clusters of processors to minimize communication costs and to avoid bandwidth contention caused by overlapping jobs. This report introduces new allocation strategies and performance metrics based on space-filling curves and one dimensional allocation strategies. These algorithms are general and simple. Preliminary simulations and Cplant experiments indicate that both space-filling curves and one-dimensional packing improve processor locality compared to the sorted free list strategy previously used on Cplant. These new allocation strategies are implemented in Release 2.0 of the Cplant System Software that was phased into the Cplant systems at Sandia by May 2002. Experimental results then demonstrated that the average number of communication hops between the processors allocated to a job strongly correlates with the job's completion time. This report also gives processor-allocation algorithms for minimizing the average number of communication hops between the assigned processors for grid architectures. The associated clustering problem is as follows: Given n points in {Re}d, find k points that minimize their average pairwise L{sub 1} distance. Exact and approximate algorithms are given for these optimization problems. One of these algorithms has been implemented on Cplant and will be included in Cplant System Software, Version 2.1, to be released. In more preliminary work, we suggest improvements to the scheduler separate from the allocator.

  4. The crucial relationship among energy commodity prices: Evidence from the Spanish electricity market

    International Nuclear Information System (INIS)

    The main purpose of this article is twofold to analyze: (a) the long-term relation among the commodities prices and between spot electricity market price and commodity prices, and (b) the short-term dynamics among commodity prices and between electricity prices and commodity prices. Data between 2002 and 2005 from the Spanish electricity market was used. Econometric methods were used in the analysis of the commodity spot price, namely the vector autoregression model, the vector error correction model and the granger causality test. The co-integration approach was used to analyze the long-term relationship between the common stochastic trends of four fossil fuel prices. One of the findings in the long-term relation is that the prices of fuel and the prices of Brent are intertwined, though the prices of Brent ten to 'move' to reestablish the price equilibrium. Another finding is that the price of electricity is explained by the evolution of the natural gas series. - Highlights: → We model energy commodity prices in the Spanish electricity market. → We examine the short and long-term relationships among commodities prices. → We examine short and long-term relationships using co-integration techniques. → We found that in the long run the prices of fuel and Brent are intertwined. → The evolution of price of electricity is explained by the evolution of price of gas.

  5. Agricultural and oil commodities: price transmission and market integration between US and Italy

    2014-08-01

    Full Text Available Purpose of this article it to get some evidences of market interaction between United States and Italy using the time series analysis of spot prices spanning from January 1999 to May 2012 for crude oil and three ag-commodities: wheat, corn and soybean. These crops have been selected for their relevance in ag-commodity exchanges between US and Italy markets. The integration between US and Italy agricultural markets is hypothesized for the consistent volume of crop traded between these two countries while the price transmission is related to the leading price signals of the CBT (Chicago Board of Trade. The integration between oil and ag-commodity markets is suggested both by the large use of energy intensive inputs, (fertilizer, seed, machinery in production of these ag-commodities, and their use in biofuel production. The results suggest: a for US market the evidence of market integration between crude oil and US ag-commodities; b for Italy the integration with US ag-commodity markets and less evidence of integration with the oil market. These results are valuable information both for the agents and policy makers contributing to improve the information accuracy to predict the price movements used by marketing operators for their strategies and policy makers to set up policies to re-establish conditions of market efficiency and allocate these ag-commodities in alternative market channels.

  6. Development of nuclear technology for improving quality and shelf-life on food commodities

    International Nuclear Information System (INIS)

    The availability and sustain ability food regarding safety, nutritive, and remaining good palatability are the basic needs of human in order to stay alive and keep healthy. The process must follow the existing standard-guidelines (Good Manufacturing Practices/GMP and Good Irradiation Practices/GIP) if ionizing radiation will be implemented for such purposes because of its effectiveness, efficient, and practical in comparison with conventional methods. Nevertheless application of nuclear technique for improving the safety and extending the shelf-life of foods for human consumption, a proper regulation and legalization from the local government is needed. Commercialization of irradiated food in Indonesia has been stipulated under decree of PERMENKES No. 826/MENKES /PER/XII/1987, No.152/MENKES/SK/II/1995 and Food Law of the Republic of Indonesia No.7/1996. Commercially, besides Indonesia, other countries within Asia and the Pacific region such as India, Thailand, and Vietnam have implemented nuclear technique on food commodities for quarantine, sanitation and sterilization purposes both for local consumption and export to European Countries, USA and Australia. Public education should be more conducted in some effective ways and keep on going to avoid misconception about the technology itself. (author)

  7. An equilibrium pricing model for weather derivatives in a multi-commodity setting

    International Nuclear Information System (INIS)

    Many industries are exposed to weather risk. Weather derivatives can play a key role in hedging and diversifying such risk because the uncertainty in a company's profit function can be correlated to weather condition which affects diverse industry sectors differently. Unfortunately the weather derivatives market is a classical example of an incomplete market that is not amenable to standard methodologies used for derivative pricing in complete markets. In this paper, we develop an equilibrium pricing model for weather derivatives in a multi-commodity setting. The model is constructed in the context of a stylized economy where agents optimize their hedging portfolios which include weather derivatives that are issued in a fixed quantity by a financial underwriter. The supply and demand resulting from hedging activities and the supply by the underwriter are combined in an equilibrium pricing model under the assumption that all agents maximize some risk averse utility function. We analyze the gains due to the inclusion of weather derivatives in hedging portfolios and examine the components of that gain attributable to hedging and to risk sharing. (author)

    This study supplements previous regime-switching studies on WTI crude oil and finds two possible volatility regimes for the strategic commodity prices of Brent oil, WTI oil, copper, gold and silver, and the S and P 500 index, but with varying high-to-low volatility ratios. The dynamic conditional correlations (DCCs) indicate increasing correlations among all the commodities since the 2003 Iraq war but decreasing correlations with the S and P 500 index. The commodities also show different volatility persistence responses to financial and geopolitical crises, while the S and P 500 index responds to both financial and geopolitical crises. Implications are discussed.

  14. On the link between oil and commodity prices: a panel VAR approach

    International Nuclear Information System (INIS)

    The aim of this paper is to study the relationships between the price of oil and a large dataset of commodity prices, relying on panel data settings. Using second generation panel co-integration tests, our findings show that the WTI and commodity prices are not linked in the long term. Nevertheless, considering our results in causality tests, we show that short-run relations exist, mainly from the price of crude oil to commodity prices. We thus implement a panel VAR estimation with an impulse response function analysis. Two main conclusions emerge: (i) fast co-movements are highlighted, while (ii) market efficiency is emphasized.

  1. Final Technical/Scientific Report: Commodity Scale Thermostable Enzymatic Transformations

    Energy Technology Data Exchange (ETDEWEB)

    James J. Lalonde; Brian Davison

    2003-08-30

    The conversion of corn starch to high fructose corn-syrup sweetener is a commodity process, producing over 3 billion kg/y. In the last step of the process, an enzyme catalyst is used to convert glucose to the much sweeter sugar fructose. Due to incomplete conversion in the last step, the syrup must be purified using a chromatographic separation technique, which results in equal quantities of water being added to the syrup, and finally the water must be evaporated (up to 1 lb of water/lb of syrup). We have estimated the energy requirement in the evaporation step to be on the order of 13 billion BTU's/y. This process inefficiency could be eliminated if a thermostable form of glucose isomerase (GI), the enzyme catalyst used in the final step, was developed. Our chosen strategy was to develop an immobilized form of the enzyme in which the protein is first crystallized and then chemically cross-linked to form an insoluble particle. This so-called cross-linked enzyme crystal (CLE C(reg. sign)) technology had been shown to be a powerful method for enzyme stabilization for several other protein catalysts. In this work we have developed more than 30 CLEC preparations of glucose isomerase and tested them for activity and stability. We found these preparations to be highly active, with a 10-50 fold rate per gram of catalyst increase over existing commercial catalysts. The initial rates were also higher at higher temperatures as expected, however the efficiency of the CLEC GI preparations unexpectedly rapidly decreased to a low constant value with use at the higher temperatures. At this point, the source of this activity loss is unclear, however during this loss, the catalyst is found to form a solid mass indicating either breakage of the chemical cross-links or simple aggregation of the particles. It is likely that the increased mass transfer resistance due to this agglomeration is a major component of the activity loss. This research suggests that one potentially

  4. Is there co-movement of agricultural commodities futures prices and crude oil?

    International Nuclear Information System (INIS)

    Even though significant attempts have appeared in literature, the current perception of co-movement of commodity prices appear inadequate and static. In particular we focus on price movements between crude oil futures and a series of agricultural commodities and gold futures. A comparative framework is applied to identify changes in relationships through time and various cointegration methodologies and causality tests are employed. Our results indicate that co-movement is a dynamic concept and that some economic and policy development may change the relationship between commodities. Furthermore we show that biofuel policy buffers the co-movement of crude oil and corn futures until the crude oil prices surpass a certain threshold. - Highlights: → We show that co-movement of commodity futures is a temporal concept. → A variation in parallel movement between 2 large periods occurs. → Biofuel policy buffers parallel movement of corn and crude oil futures

  6. Market interdependence among commodity prices based on information transmission on the Internet

    Science.gov (United States)

    Ji, Qiang; Guo, Jian-Feng

    2015-05-01

    Human behaviour on the Internet has become a synchro-projection of real society. In this paper, we introduce the public concern derived from query volumes on the Web to empirically analyse the influence of information on commodity markets (e.g., crude oil, heating oil, corn and gold) using multivariate GARCH models based on dynamic conditional correlations. The analysis found that the changes of public concern on the Internet can well depict the changes of market prices, as the former has significant Granger causality effects on market prices. The findings indicate that the information of external shocks to commodity markets could be transmitted quickly, and commodity markets easily absorb the public concern of the information-sensitive traders. Finally, the conditional correlation among commodity prices varies dramatically over time.

    Directory of Open Access Journals (Sweden)

    Adam Zaremba

    2016-01-01

    Full Text Available The aim of this paper is to investigate the impact of the financialization of commodity markets on the profitability of strategies based on momentum and term structure. The performance of an array of portfolios from double-sorts on non-commercial traders’ participation, historical returns and term spreads are tested against a risk model. The analysis covers the listing of 26 commodities in the period 1986 – 2013. First and foremost, the paper provides a fresh evidence for the validity of strategies based on momentum and term structure investing in commodity markets. Secondly, it proves that term structure strategies generate significantly higher performance results in non-financialized markets. Moreover, it supports the thesis that market financialization adversely affects momentum profits. The results are important in terms of tactical and strategic asset allocation in commodity markets. They imply that investors who implement momentum or term structure based strategies should also consider the composition of market participants.

  8. Regime shift in fertilizer commodities indicates more turbulence ahead for food security.

    Directory of Open Access Journals (Sweden)

    James J Elser

    Full Text Available Recent human population increase has been enabled by a massive expansion of global agricultural production. A key component of this "Green Revolution" has been application of inorganic fertilizers to produce and maintain high crop yields. However, the long-term sustainability of these practices is unclear given the eutrophying effects of fertilizer runoff as well as the reliance of fertilizer production on finite non-renewable resources such as mined phosphate- and potassium-bearing rocks. Indeed, recent volatility in food and agricultural commodity prices, especially phosphate fertilizer, has raised concerns about emerging constraints on fertilizer production with consequences for its affordability in the developing world. We examined 30 years of monthly prices of fertilizer commodities (phosphate rock, urea, and potassium for comparison with three food commodities (maize, wheat, and rice and three non-agricultural commodities (gold, nickel, and petroleum. Here we show that all commodity prices, except gold, had significant change points between 2007-2009, but the fertilizer commodities, and especially phosphate rock, showed multiple symptoms of nonlinear critical transitions. In contrast to fertilizers and to rice, maize and wheat prices did not show significant signs of nonlinear dynamics. From these results we infer a recent emergence of a scarcity price in global fertilizer markets, a result signaling a new high price regime for these essential agricultural inputs. Such a regime will challenge on-going efforts to establish global food security but may also prompt fertilizer use practices and nutrient recovery strategies that reduce eutrophication.

    2004-01-01

    A brief surrey of ongoing research work done for improving and enhancing the properties of commodity polymers by the author and author's colleagues is given in this paper. A series of high performance polymers and polymer nanomaterials were successfully prepared through irradiation and stress-induced reactions of polymers and hydrogen bonding. The methods proposed are viable, easy in operation, clean and efficient.1. The effect of irradiation source (UV light, electron beam, γ -ray and microwave), irradiation dose, irradiation time and atmosphere etc. on molecular structure of polyolefine during irradiation was studied. The basic rules of dominating oxidation, degradation and cross-linking reactions were mastered. Under the controlled conditions, cross-linking reactions are prevented, some oxygen containing groups are introduced on the molecular chain of polyolefine to facilitate the interface compatibility of their blends. A series of high performance polymer materials: u-HDPE/PA6,u-HDPE/CaCO3, u-iPP/STC, γ-HDPE/STC, γ-LLDPE/ATH, e-HDPE, e-LLDPE and m-HDPEfilled system were prepared (u- ultraviolet light irradiated, γ- γ-ray irradiated, e- electron beam irradiated, m- microwave irradiated)2. The effect of ultrasonic irradiation, jet and pan-milling on structure and changes in properties of polymers were studied. Imposition of critical stress on polymer chain can cause the scission of bonds to form macroradicals. The macroradicals formed in this way may recombine or react with monomer or other radicals to form linear, branched or cross-linked polymers or copolymers. About 20 kinds of block/graft copolymers have been synthesized from polymer-polymer or polymer-monomer through ultrasonic irradiation.Through jet-milling, the molecular weight of PVC is decreased somewhat, the intensity of its crystalline absorption bonds becomes indistinct. The processability, the yield strength, strength at break and elongation at break of PVC get increased quite a lot after

    WindowsTM development environments and tools are available and offer a rich set of capabilities, 5. The WindowsTM 2000 provides a stable client platform, Therefore, five studies were proposed, developed, and are in the current process of deployment which dramatically reduces the cost of operations, maintenance, refurbishment, and deployment of a ground system. Restating and refining the basic premise stated earlier, it is possible to enhance operations through the replacement of hardware and software components with commodity based items wherever applicable. This will dramatically reduce the overall lifecycle cost of the project. The first study leveraged the POIF S secure, three-tier, web architecture to replace the client workstations with lower cost PC platforms. A second study initiated a review of COTS products to examine the level of added value of each product. This study included replacement of some COTS products with custom code, deletions, substitutions, and consolidation of COTS products. Studies three and four reviewed the server architectures of the data distribution systems and Enhanced HOSC System (EHS) command and telemetry system to propose migration to new platforms, both software and hardware. The final study reviewed current IP communication technologies, developed an operational model for flight operations, and demonstrated that voice over IP was practical and could be integrated into operations.

    Full Text Available This study was initiated to achieve the specific objectives as identification of factors that affect market participation decision of households and identification of factors that determine the volume of market supply of pepper. In order to acquire the relevant data, formal and informal methods of data collection were accomplished. To differentiate factors affecting the market participation and the amount of pepper sold, the Heckman Two-Stage econometric model was employed. The result revealed that market participation decision of households and amount of pepper sold were significantly affected by many of the variables hypothesized to have impact on the explained variable. In order to settle price fluctuations and to strengthen the bargaining power of producers, there should be product grading for market standardization. Furthermore, market competitiveness, structure and efficiency can be improved through facilitating pepper market strategies training as it helps producers and other interested bodies better involve in the commodity market. 

  12. Phytosanitary irradiation of fresh tropical commodities in Hawaii: Generic treatments, commercial adoption, and current issues

    International Nuclear Information System (INIS)

    Hawaii is a pioneer in the use of phytosanitary irradiation. The commercial X-ray irradiation facility, Hawaii Pride LLC, has been shipping papaya and other tropical fruits and vegetables to the United States mainland using irradiation for 11 years. Irradiation is an approved treatment to control quarantine pests in 17 fruits and 7 vegetables for export from Hawaii to the US mainland. Hawaiian purple sweet potato is the highest volume product with annual exports of more than 12 million lbs (5500 t). The advent of generic radiation treatments for tephritid fruit flies (150 Gy) and other insects (400 Gy) will accelerate commodity export approvals and facilitate worldwide adoption. Lowering doses for specific pests and commodities can lower treatment costs and increase capacity owing to shorter treatment times, and will minimize any quality problems. Current impediments to wider adoption include the 1 kGy limit for fresh horticultural products, the labeling requirement, and non-acceptance of phytosanitary irradiation in Japan, the European Union, and elsewhere. Irradiation has potential as a treatment for unregulated imports to prevent new pest incursions. - Highlights: ► Irradiation is used to control quarantine insects in exported fresh commodities. ► Hawaii exported 5.7 t of tropical produce using irradiation in 2010. ► Generic radiation treatments will accelerate commodity export approvals. ► Lowering the dose for specific commodities will reduce costs/maintain quality. ► Current issues include the 1 kGy dose limit and labeling requirements.

  13. Determine the optimal carrier selection for a logistics network based on multi-commodity reliability criterion

    Science.gov (United States)

    Lin, Yi-Kuei; Yeh, Cheng-Ta

    2013-05-01

    From the perspective of supply chain management, the selected carrier plays an important role in freight delivery. This article proposes a new criterion of multi-commodity reliability and optimises the carrier selection based on such a criterion for logistics networks with routes and nodes, over which multiple commodities are delivered. Carrier selection concerns the selection of exactly one carrier to deliver freight on each route. The capacity of each carrier has several available values associated with a probability distribution, since some of a carrier's capacity may be reserved for various orders. Therefore, the logistics network, given any carrier selection, is a multi-commodity multi-state logistics network. Multi-commodity reliability is defined as a probability that the logistics network can satisfy a customer's demand for various commodities, and is a performance indicator for freight delivery. To solve this problem, this study proposes an optimisation algorithm that integrates genetic algorithm, minimal paths and Recursive Sum of Disjoint Products. A practical example in which multi-sized LCD monitors are delivered from China to Germany is considered to illustrate the solution procedure.

  14. Techniques for Analyzing the Attractiveness of International Commodity Markets Under Conditions of Economic Globalization

    Directory of Open Access Journals (Sweden)

    Olha Pryhara

    2006-03-01

    Full Text Available This article examines existing techniques and proposes its own for analyzing the attractiveness of international commodity markets in light of the globalization of world economic processes. Taking into account the supranational nature of the world economic environment when examining categories in the attractiveness of international commodity markets, the author introduces a multilevel system of indicators: market attractiveness at the mega-level – global level; market attractiveness at the macro-level national level; market attractiveness at the mezo-level – level of an individual sector. The attractiveness of international commodity markets is considered to be the degree of conformity between market environment factors and the mega-, macro- and mezo-levels of the economic interests of enterprises concerning the entry into and strategies for their activity on the international commodity markets in the short-, medium- and long-term. The author designs a stage-by-stage technique for strategically analyzing the attractiveness of international commodity markets in order to frame efficient market strategies of enterprises. Relying on the proposed techniques, she rates the integrated indicators of market accessibility and the possibility of realizing the economic interests of enterprises in target markets, bringing the index data into a matrix of «market accessibility – opportunity for realizing the economic interests of enterprises.» The analysis of a country’s position in the matrix makes it possible to frame efficient market strategies for enterprises.

  15. Evaluating the damage associated with intentional supply deprivation in multi-commodity network

    International Nuclear Information System (INIS)

    This paper presents a method for evaluating an expected damage associated with nodes deprivation of supply of commodities in multi-commodity networks with a given topology as a result of intentional attack on randomly chosen network links. The method is based on a Monte Carlo simulation approach for evaluating the expected number of nodes deprived of all possible subsets of commodities. It also uses the contest success function that evaluates destruction probability of individual links as a function of per-link attack and defense efforts. It is assumed that the defender has no information about the attacker's actions and the attacker has no information about the network structure. The method allows the analysts to compare different solutions of expected damage reduction under conditions of uncertainty. Illustrative examples are presented

    Full Text Available We present a novel variation of the vehicle routing problem (VRP. Single commodity cargo with pickup and delivery service is considered. Customers are labeled as either cargo sink or cargo source, depending on their pickup or delivery demand. This problem is called a single commodity vehicle routing problem with pickup and delivery service (1-VRPPD. 1-VRPPD deals with multiple vehicles and is the same as the single-commodity traveling salesman problem (1-PDTSP when the number of vehicles is equal to 1. Since 1-VRPPD specializes VRP, it is hard in the strong sense. Iterative modified simulated annealing (IMSA is presented along with greedy random-based initial solution algorithm. IMSA provides a good approximation to the global optimum in a large search space. Experiment is done for the instances with different number of customers and their demands. With respect to average values of IMSA execution times, proposed method is appropriate for practical applications.

    Marcela Lascsáková

    2015-09-01

    Full Text Available In the paper the numerical model based on the exponential approximation of commodity stock exchanges was derived. The price prognoses of aluminium on the London Metal Exchange were determined as numerical solution of the Cauchy initial problem for the 1st order ordinary differential equation. To make the numerical model more accurate the idea of the modification of the initial condition value by the stock exchange was realized. By having analyzed the forecasting success of the chosen initial condition drift types, the initial condition drift providing the most accurate prognoses for the commodity price movements was determined. The suggested modification of the original model made the commodity price prognoses more accurate.

    Filipe Monteiro de Castro Albert

    2014-01-01

    Full Text Available Brazil is one of the world’s largest base materials exporters, and this paper examines through large time series samples whether the Brazilian Real can be characterized as a commodity currency. The Real/US dollar real exchange rate and a real commodity prices index are found to be non-stationary and not cointegrated, while a risk premium appeared to have a large and statistically significant long term relationship with exchange rate movements. Combined first difference models showed that real exchange rate elasticity to risk premium is twice as large as to commodity prices, although both variables have considerable influence. Some specifications outperformed a random walk model with respect to root mean square forecast errors for many horizons, but the latter still better determined the exchange rate in longer terms.

  19. Developing an organized commodity exchange in Ghana: Challenges and economic prospects

    Directory of Open Access Journals (Sweden)

    Mohammed Iddrisu Ngmenipuo

    2015-04-01

    Full Text Available We have examined challenges and economic prospects of establishing an organized Commodity Exchange in Ghana. We find that such a market will result in reduction in post-harvest losses through price stability, improvement in commodity price risk and credit risk management, provision of a transparent and competitive price discovery mechanism, reduction in transaction and marketing costs, and avoidance of making the mistakes of others. However, we also identify the challenges that should be resolved such as lack of laws and regulations specifically pertaining to the commodity exchange; inadequate financial support; lack of trading infrastructure; inadequate volume; liquidity problem; smallholder farms; lack of understanding of trading instruments; and government/political interference to this end. Overall policy implications suggest inadequate infrastructure and capacity building of market participants should be enhanced.

  20. AN OVERVIEW OF MAJOR SOURCES OF DATA AND ANALYSES RELATING TO PHYSICAL FUNDAMENTALS IN INTERNATIONAL COMMODITY MARKETS

    OpenAIRE

    Pilar Fajarnes

    2011-01-01

    The debate on whether price movements in commodity markets are determined by changes in physical supply and demand fundamentals or by the speculative effects of financial investors seems to find some element of agreement on one particular point: the need for increased transparency and improved information on futures markets and physical commodity markets. This discussion paper provides an assessment of the current situation with regard to availability of information on physical commodity mark...

  1. Managing commodity price risks: The cases of cotton in Burkina Faso and Mozambique and coffee in Ethiopia

    OpenAIRE

    Staritz, Cornelia; Tröster, Bernhard; Küblböck, Karin

    2015-01-01

    Price instability is a major concern for commodity producers in developing countries. Commodity derivative markets have become the central pricing mechanism for international commodity trade. This is problematic given the high volatility and increased short-termism of these markets in the context of financialisation. The effects on producers depend on the market structure in producer countries. Burkina Faso and Mozambique have different types of national cotton price stabilization schemes in ...

    2013-01-01

    Commodity price shocks are an important type of external shock and are often cited as a problem for economic growth in sub-Saharan Africa. This paper quantifies the impact of agricultural commodity price shocks using a near vector autoregressive model. The novel aspect of this model is that we define an auxiliary variable that can potentially capture the definition of a price shock that allows us to determine whether the response of per capita Gross domestic product (GDP) growth in sub-Sahara...

  7. A strong argument for using non-commodities to generate electricity

    International Nuclear Information System (INIS)

    An optimal control approach towards generating electricity is used to analyze the trade-off between using of primary sources which are regarded as commodities, such as fossil fuels, biomass and water to generate electricity, and exploiting these sources for their other economic uses (for example, in the petrochemical industry, in the production of fuels, in agriculture, in steelmaking, and so forth). In order to do so, a dynamic model is presented which establishes relationships between economic growth, the fossil fuel, water and biomass sectors, and energy policies, based on the application of the Pontryagin Maximum Principle. Among other results, the analysis establishes that, under the optimal path, the price of commodities for non-energy uses should be twice the price of the energy assets. This indicates that sources which are not commodities such as solar energy, wind energy, and geothermal energy, should be used to generate electricity. - Highlights: • We used an optimal control approach to analyze the trade-off between the multiple uses of energy resource. • We used a dynamic model which establishes relationships between economic growth, the fossil fuel, water and biomass sectors. • The analysis establishes that the price of commodities for non-energy uses should be twice the price of the energy assets

  16. The top 50 commodity chemicals: Impact of catalytic process limitations on energy, environment, and economics

    Energy Technology Data Exchange (ETDEWEB)

    Tonkovich, A.L.Y.; Gerber, M.A.

    1995-08-01

    The production processes for the top 50 U.S. commodity chemicals waste energy, generate unwanted byproducts, and require more than a stoichiometric amount of feedstocks. Pacific Northwest Laboratory has quantified this impact on energy, environment, and economics for the catalytically produced commodity chemicals. An excess of 0.83 quads of energy per year in combined process and feedstock energy is required. The major component, approximately 54%, results from low per-pass yields and the subsequent separation and recycle of unreacted feedstocks. Furthermore, the production processes, either directly or through downstream waste treatment steps, release more than 20 billion pounds of carbon dioxide per year to the environment. The cost of the wasted feedstock exceeds 2 billion dollars per year. Process limitations resulting from unselective catalysis and unfavorable reaction thermodynamic constraints are the major contributors to this waste. Advanced process concepts that address these problems in an integrated manner are needed to improve process efficiency, which would reduce energy and raw material consumption, and the generation of unwanted byproducts. Many commodity chemicals are used to produce large volume polymer products. Of the energy and feedstock wasted during the production of the commodity chemicals, nearly one-third and one-half, respectively, represents chemicals used as polymer precursors. Approximately 38% of the carbon dioxide emissions are generated producing polymer feedstocks.

  10. Using Discrete Event Simulation to Model Integrated Commodities Consumption for a Launch Campaign of the Space Launch System

    Science.gov (United States)

    Leonard, Daniel; Parsons, Jeremy W.; Cates, Grant

    2014-01-01

    In May 2013, NASA's GSDO Program requested a study to develop a discrete event simulation (DES) model that analyzes the launch campaign process of the Space Launch System (SLS) from an integrated commodities perspective. The scope of the study includes launch countdown and scrub turnaround and focuses on four core launch commodities: hydrogen, oxygen, nitrogen, and helium. Previously, the commodities were only analyzed individually and deterministically for their launch support capability, but this study was the first to integrate them to examine the impact of their interactions on a launch campaign as well as the effects of process variability on commodity availability. The study produced a validated DES model with Rockwell Arena that showed that Kennedy Space Center's ground systems were capable of supporting a 48-hour scrub turnaround for the SLS. The model will be maintained and updated to provide commodity consumption analysis of future ground system and SLS configurations.

  11. Global Commodity Chains & World Income Inequalities: The Missing Link of Inequality and the “Upgrading” Paradox

    Directory of Open Access Journals (Sweden)

    Benjamin D. Brewer

    2015-08-01

    Full Text Available This article links key findings from two major research literatures within contemporary development and globalization studies: global commodity/value chains, and world income inequalities. Forging this missing link exposes what I call the “upgrading paradox” within commodity and value chain analysis. The paradox hinges on the disconnect between the global commodity/value chain literature’s focus on the potential for firms and nations to “upgrade” their position within chains and the roots of the global commodity chain construct in world-systems analysis, a theoretical framework that rejects the potential for widespread and generalizable developmental progress. Findings from the world income inequalities literature do indeed confirm the paradoxical nature of the upgrading discourse, so I conclude by discussing two potential paths for a “post-paradox” commodity chain analysis.

    Cosmetics and certain commodities are applied or used by consumers directly on the skin. Creams may remain on the skin for longer periods, hair is dyed multiple times per year, nickel ions can be released from studs and piercings in areas of skin damage or migrate from toy materials into the skin of children. Accordingly, using or handling such products always entails a risk for developing a contact allergy. Moreover, daily usage and repeated contacts to certain cosmetics and commodities might lead to repeated elicitation of contact eczema in people already sensitized against allergenic ingredients. Unfortunately, contact allergy is not curable. For the assessment of the allergenic potential of chemicals, only testing based on animal experiments was available in the past. In 2003, the 7(th) amendment of the Cosmetics Directive 76/768/EWG laid down a ban on animal testing of cosmetic ingredients and from 2013 a general marketing ban of such products as well. Therefore, the development and validation of non-animal methods for assessing the toxicological endpoint sensitization/allergenic potency of chemicals is a major task for the years ahead and remains equally a challenge for industry and regulatory agencies.

In addition to every kind of statuette, bread, plates, knives, forks, tablecloth, furniture, fruit, flowers, and trees that were all said to be so lifelike that is was only when the napkin broke in his hand that the astonished King...

  15. Understanding Grades and Standards: and how to apply them

    2000-01-01

    With the expanding globalization of trade, grades and standards help to set the ‘rules of the game’ and their implications for developing countries are becoming increasingly relevant. While they are clearly important to trade, their formation and utilization is also undergoing a shift from being neutral market lubricants to also being tools of product differentiation. This implies a fundamental shift in the role of standards from just reducing transaction costs of commodity market particip...

  16. Summary report on the use of irradiation as a quarantine treatment of agricultural commodities

    International Nuclear Information System (INIS)

    Considerable data are available to demonstrate that gamma irradiation is an effective quarantine treatment for papaya infested with fruit fly species found in Hawaii. These data are acceptable to the USDA-APHIS as a quarantine treatment for this commodity. However, its practical application can be realized only when FDA approves the use of irradiation, either for this purpose alone or as a process of food preservation. Additional data are needed to develop quarantine treatment schedules for irradiation of other commodities such as citrus, stone fruits, tropical fruits, etc., against these and other insect species. For this reason, a Consultant Meeting was convened at the East-West Center, University of Hawaii, Honolulu, Hawaii from 21 to 23 November, 1983, to evaluate existing data and to define future activities to establish the possible use of irradiation as an acceptable quarantine treatment

  17. Speculation and volatility spillover in the crude oil and agricultural commodity markets: A Bayesian analysis

    International Nuclear Information System (INIS)

    This paper assesses factors that potentially influence the volatility of crude oil prices and the possible linkage between this volatility and agricultural commodity markets. Stochastic volatility models are applied to weekly crude oil, corn, and wheat futures prices from November 1998 to January 2009. Model parameters are estimated using Bayesian Markov Chain Monte Carlo methods. Speculation, scalping, and petroleum inventories are found to be important in explaining the volatility of crude oil prices. Several properties of crude oil price dynamics are established, including mean-reversion, an asymmetry between returns and volatility, volatility clustering, and infrequent compound jumps. We find evidence of volatility spillover among crude oil, corn, and wheat markets after the fall of 2006. This can be largely explained by tightened interdependence between crude oil and these commodity markets induced by ethanol production.

    Kockums Chemical AB, Malmö, Sweden, has developed a biochemical indicator, the i-point TTM (Time-Temperature Monitor). The indicator responds to temperature in much the same way as perishable commodities in which loss of quality is directly related to the combined effects of the degree and the duration of storage temperature. Primary application of such indicators are expected for frozen, refrigerated and fresh food products. The device can be useful in monitoring the handling of various temperature sensitive noon-food products as well. Reacting at a relatively low rate under optimum temperture conditions and at accelerated rates as temperature rises, the indicator chemically integrates and accumulates both the length and degree of all temperature experiences. When pre-selected time-temperature limits have been exceeded a distinct irreversible color change will occur, indicating that action is required--the particular depending upon the use being made of the commodity.

    Recent advances in low-end processor and network technology have made it possible to build a "supercomputer" out of commodity components. We develop simple models of the NAS Parallel Benchmarks version 2 (NPB 2) to explore the cost/performance trade-offs involved in building a balanced parallel computer supporting a scientific workload. By measuring single processor benchmark performance, network latency, and network bandwidth, and using closed form expressions detailing the number and size of messages sent by each benchmark, our models predict benchmark performance to within 30%. A comparison based on total system cost reveals that current commodity technology (200 MHz Pentium Pros with 100baseT Ethernet) is well balanced for the NPBs up to a total system cost of around $ 1,000,000.

  20. The Impact of the Global Commodity and Financial Crises on Poverty in Vietnam

    DEFF Research Database (Denmark)

    Thurlow, James; Tarp, Finn; McCoy, Simon;

    Economic growth in Vietnam has been fairly resilient to the global commodity and financial crises, but it is unclear why. In addition, the impact of the crises on employment and poverty is in dispute. We develop a dynamic computable general equilibrium model to decompose impacts and estimate...... distributional outcomes. Our results indicate that the 2008 commodity crisis increased employment and reduced poverty by favouring labour-intensive exports, especially in agriculture. The 2009 financial crisis reversed these gains. It pushed more than a million workers into unemployment and about 3 million...... people below the US$2-a-day poverty line, with the vast majority of these being rural dwellers. The net effect of the crises left Vietnam.....
