This paper presents the proposal for establishing in a parallel way to Flamex project, the compensation in the intermediate tension network for the increment in reactive power supplied to the domestic user. This is due to the following three phenomena that occur in replacing incandescent light bulbs with fluorescent lamps: a) A fluorescent lamp has a power factor of 0.9; consequently it requires the supply of a reactive power of about 50% of its capacity. b) In replacing an incandescent light bulb for a fluorescent lamp, approximately 80% of its capacity is not supplied, this leads to the disappearance of a good deal of the user`s purely resistive load, that will cause that its natural power factor is decreased from 0.91 to 0.86 lagging. c) In decreasing the annual maximum demand in the distribution circuit in a greater proportion than the decrease of the annual consumption, their load factors and the annual losses will be increased and therefore the share of its annual energy losses will be increased in about 18.9%. The above, gives rise to the fact that the compensation of reactive power by means of the installation of capacitor banks in the main leads of the distribution circuit, turns out to be a highly appealing technical-economical solution, with a Benefit/Cost rate of 4, a return time of the investment of 2 years and a net benefit of $4.78/user (Pesos).

Wind energy is nowadays one of the most cost-effective and practical options for electric generation from renewable resources. However, increased penetration of wind generation causes the power networks to be more depend on, and vulnerable to, the varying wind speed. Modeling is a tool which can provide valuable information about the interaction between wind farms and the power network to which they are connected. This paper develops a realistic characterization of a wind generator. The wind generator model is incorporated into an algorithm to investigate its contribution to the stability of the power network in the time domain. The tool obtained is termed dynamic power flow. The wind generator model takes on account the wind speed and the reactive power consumption by induction generators. Dynamic power flow analysis is carried-out using real wind data at 10-minute time intervals collected for one meteorological station. The generation injected at one point into the network provides active power locally and is found to reduce global power losses. However, the power supplied is time-varying and causes fluctuations in voltage magnitude and power flows in transmission lines. [Spanish] La energia eolica es hoy en dia una de las opciones mas efectivas y practicas para la generacion de electricidad a partir de energias renovables. Sin embargo, el incremento de la penetracion de energia eolica provoca que los sistemas de potencia se vuelvan mas dependientes y vulnerables a las variaciones de la velocidad del viento. El modelado es una herramienta que provee informacion valiosa de la interaccion dinamica entre las turbinas eolicas y las redes de potencia a las que se conectan. El presente articulo desarrolla una caracterizacion realista de un modelo de la turbina eolica. El modelo de la turbina eolica se incorpora a un algoritmo para el analisis de su contribucion a la estabilidad de una red electrica en el dominio del tiempo. La herramienta obtenida se conoce como flujos

Full Text Available Desde el siglo XIX Brasil fue adaptando sus estrategias de soft power (poder blando con la meta de afirmar su poderío político y económico en América Latina y en el mundo, en contraposición a otros poderes hegemónicos regionales y mundiales. Sin embargo, sus rivalidades con potencias regionales, como Argentina o Venezuela y, con Estados Unidos, a nivel regional y mundial, nunca llevaron al coloso suramericano a optar por confrontaciones bélicas. Sus estrategias y opciones de política exterior tuvieron siempre en mira la consolidación del país por vía no violenta y a largo plazo. El presente artículo debate la pregunta-problema de si la nación suramericana podrá seguir la línea de poder blando que ha respetado, por siglos, desde su independencia, o será tentada a privilegiar el hard power para lograr, finalmente, ser reconocida como gran potencia en el siglo XXI.

Preliminary risk assessments of the small HTGR

International Nuclear Information System (INIS)

Everline, C.J.; Bellis, E.A.

1985-05-01

Preliminary investment and safety risk assessments were performed for a preconceptual design of a four-module 250-MW(t) side-by-side steel-vessel pebble bed HTGR plant. Broad event spectra were analyzed involving component damage resulting in unscheduled plant outages and fission product releases resulting in offsite doses. The preliminary assessment indicates at this stage of the design that two categories of events govern the investment risk envelope: primary coolant leaks which release some circulating and plate-out activity that contaminates the confinement and turbogenerator damage which involves extensive turbine blade failure. Primary coolant leaks are important contributors because associated cleanup and decontamination requirements result in longer outages that arise from other events with comparable frequencies. Turbogenerator damage is the salient low-frequency investment risk accident due to the relatively long outages being experienced in the industry. Thermal transients are unimportant investment risk contributors because pressurized core heatups cause little damage, and depressurized core heatups occur at negligible frequencies relative to the forced outage goal. These preliminary results demonstrate investment and safety risk goal compliance at this stage in the design process. Studies are continuing in order to provide valuable insights into risk-significant events to assure a balanced approach to meeting user and regulatory requirements

Hybrid power systems for an autonomous power supply are based on different renewable and fossil energy sources. They are considered as a good option for the power supply of remote areas. In these systems an energy storage is a vital necessity and very often this storage will consist of batteries which are generally connected in series and parallel arrays, or both. In Mexico as in other countries, the most extensively use batteries used for this application are the stationary and electric car type deep cycle batteries. However the experience with them in these systems is generally not very good. One way to overcome this problem is to maintain a regular monitoring of installing monitoring equipment, in order to make preventive actions before a developing fault can have serious consequences and in this manner increase the practical lifetime of the batteries. Unfortunately, battery monitoring is not easy task because most of the hybrid power systems are installed in remote areas which makes it difficult and expensive. In Mexico it has been not possible to maintain a regular monitoring of all hybrid power systems installed, due to the high cost of this work and the lack of founds. The hybrid power systems installed in the state of Quintana Roo are the only systems that have been continuously monitored since their installation. This paper gives an overview of the hybrid power systems installed in Mexico, focusing in the battery banks, the way they are being monitored, the main parameters used to detect possible premature problems and the method used to evaluate the battery bank conditions. Finally some results from the battery banks monitoring activities are presented.

The purpose of this study was to measure the acute effect of two explosive strength sessions on mechanical performance. In order to do that, 1 repetition maximum and maximum power load were obtained in 9 men. The experimental procedure begun five days after and it involved two training sessions. 7 bouts of 3 repetitions at maximum power load of bench press were developed in every session with a minimum rest period of three minutes. Power developed at 90% 1RM and at maximum power load were measured before and after every training day. Finally it was carried out a postest measuring. Although repeted-measures ANOVA showed significant differences between measurements at 90% 1RM , statistics analysis did not show significant differences regarding to before-after every sessions contrasts, and between measuring at maximum power load. Also, we did not find significant 1RM correlation with performance differences before-after session. Finally, it was found significant correlation between maximum strength and % 1RM associated to developed maximum power at postest.
KEY WORDS: strength, contrast load, bench press, power.

Full Text Available Aluminium alloys have good mechanical properties (high strength-to-weight ratio, corrosion resistance and good workability. Their applications are growing up, specially in the transportation industry. Weldability is however poorer than in other materials; recent advances in high power YAG lasers are the key to obtain good appearance welds and higher penetration, at industrial production rates. Results of the combination of high power YAG beams with small fiber diameters and specific filler wires are presented. It is also characterized the airborne particulated material, by-product of the laser process: emission rates, size distribution and chemical composition are given for several aluminium alloys.

El uso del Al y sus aleaciones es creciente en la fabricación de vehículos de transporte. Su soldabilidad es menor que la de otros materiales y las aleaciones presentan cierta disminución de propiedades por pérdida de aleantes y/o de su tratamiento térmico.

Full Text Available La emisión de gases efecto invernadero, causadas por el uso de combustibles fósiles y el crecimiento exponencial de la humanidad, vuelca los esfuerzos hacia la búsqueda de fuentes de energía limpia y sostenible, que satisfagan las necesidades energéticas actuales y futuras. Por lo que es imperativo, investigar y desarrollar tecnologías que aprovechen las energías renovables, una de ellas es la Ósmosis por Presión Retardada (PRO, proceso que aprovecha el gradiente de salinidad entre dos soluciones para generar electricidad, ya que la mezcla de una solución salina de concentración alta con agua fresca disipa más de 2,2 MJ/m3 de agua dulce tratada. A escala industrial, se podría aprovechar la diferencia de salinidad entre ríos y mares, cerca de los estuarios. La aplicación, viabilidad y eficiencia del proceso y la tecnología PRO, dependen de las características de la membrana semipermeable, como la potencia por unidad de área, y las propiedades fisicoquímicas y de superficie de esta. En la actualidad, se utilizan membranas de acetato de celulosa, las cuales dan potencias (1W/m2. Sin embargo, se está investigando con membranas de materiales compuestos, como, por ejemplo, las basadas en grafeno, las cuales permiten un mayor flujo de agua y potencias superiores a 5 W/m2.

OBJETIVO: Nosso objetivo foi estudar o comportamento da CPR e seus mecanismos subjacentes em camundongos com infarto do miocárdio. MÉTODOS: Seis semanas após a oclusão coronariana, a contratilidade dos Músculos Papilares (MP obtidos a partir de camundongos submetidos à cirurgia sham (C, n = 17, com infarto moderado (MMI, n = 10 e grande infarto (LMI, n = 14, foi avaliada após intervalos de repouso de 10 a 60 segundos antes e depois da incubação com cloreto de lítio (Li+ em substituição ao cloreto de sódio ou rianodina (Ry. A expressão proteica de SR Ca(2+-ATPase (SERCA2, trocador Na+/Ca2+ (NCX, fosfolambam (PLB e fosfo-Ser (16-PLB foi analisada por Western blotting. RESULTADOS: Os camundongos MMI apresentaram potenciação de CPR reduzida em comparação aos camundongos C. Em oposição à potenciação normal para camundongos C, foram observadas degradações de força pós-repouso nos músculos de camundongos LMI. Além disso, a Ry bloqueou a degradação ou potenciação de PRC observada em camundongos LMI e C; o Li+ inibiu o NCX e converteu a degradação em potenciação de CPR em camundongos LMI. Embora os camundongos MMI e LMI tenham apresentado diminuição no SERCA2 (72 ± 7% e 47 ± 9% de camundongos controle, respectivamente e expressão protéica de fosfo-Ser16-PLB (75 ± 5% e 46 ± 11%, respectivamente, a superexpressão do NCX (175 ± 20% só foi observada nos músculos de camundongos LMI. CONCLUSÃO: Nossos resultados mostraram, pela primeira vez, que a remodelação miocárdica pós-IAM em camundongos pode mudar a potenciação regular para degradação pós-repouso, afetando as proteínas de manipulação de Ca(2+ em miócitos.

2014-01-01

Full Text Available La oferta de aplicaciones y servicios multimedia para terminales móviles se hace principalmente a través de las redes celulares de tercera y cuarta generación (3G/4G existentes. El envío de los datos en este tipo de redes se realiza en modo unicast, es decir, a cada usuario se le dedican recursos de radio (ancho de banda y potencia de transmisión durante toda la sesión. Esto presenta algunos inconvenientes, tales como agotamiento rápido del ancho de banda del operador móvil, alto consumo de potencia de transmisión, incremento de la interferencia, y costos altos del servicio. Los operadores móviles requieren de nuevas tecnologías que optimicen el uso de sus recursos de radio y así lograr un mayor índice de penetración de los servicios. De ahí la necesidad de cambiar de paradigma hacia un modo de transmisión en multicast o broadcast, en el que una misma señal pueda recibirse por varios usuarios simultáneamente, de tal forma que los recursos de radio se puedan compartir. Para ello, la solución técnica sobre redes celulares LTE (Long Term Evolution se dio en la especificación 3GPP Release 6, llamada Servicio Multimedia por Broadcast/Multicast (MBMS, Multimedia Broadcast Multicast Service. La especificación de MBMS permite que una transmisión cambie de modo unicast a modo multicast a partir de un “punto de conmutación”, que determina el momento de hacer el cambio para obtener un ahorro tanto en ancho de banda como en potencia de transmisión. Este artículo presenta una evaluación para determinar los puntos de conmutación de modo de transmisión óptimos en el estándar MBMS para diferentes ambientes de propagación inalámbrica. Además, dado que MBMS se puede utilizar en topologías de Red de Frecuencia Única (SFN, Single Frequency Networks, que tienen la propiedad de “ganancia de red”, también se determina el ahorro de potencia de transmisión adicional que se obtiene en esta configuración.

Since its introduction by Dantzig and Ramser in 1959, vehicle routing problem keeps evolving in theories, applications and variability. The evolution in computing and technology are also important contributors to research in solving vehicle routing problem. The main sectors of interests among researchers and practitioners for vehicle routing problem are transportation, distribution and logistics. However, literature found that concept and benefits of vehicle routing problem are not taken advantages of by researchers in the field of investment. Other methods found used in investment include multi-objective programming, linear programming, goal programming and integer programming. Yet the application of vehicle routing problem is not fully explored. A proposal on a framework of the fund allocation optimization using vehicle routing problem is presented here. Preliminary results using FTSE Bursa Malaysia data testing the framework are also given.

[Spanish] El objetivo principal de esta tesis es el de presentar un modelo de reduccion de redes que pueda ser utilizado en la simulacion de diversos fenomenos que ocurren en la operacion de los Sistemas Electricos de Potencia (SEP). El trabajo muestra el desarrollo y aplicacion del equivalente en estudios de: Flujos de potencia en estado estable, estabilidad transitoria, comportamiento dinamico generalizado y comportamiento de la frecuencia simplificado. Este modelo surge como resultado de la observacion y analisis del comportamiento del SEP, separando efectos de: cargas, generaciones, red electrica y sus elementos en derivacion. El algoritmo utiliza un enfoque alterno a la presentacion tradicional de equivalentes, donde las cargas se ponderan en el proceso de eliminacion a sus nodos vecinos, basados en una reduccion vectorial de las lineas o transformadores que se involucran al nodo eliminado. De igual forma se transfieren los efectos de los elementos en derivacion. Los resultados asi obtenidos tienen un desajuste pequeno en potencia reactiva por lo que es necesario compensar el caso base reducido. La compensacion solo es necesaria en los nodos que fueron vecinos a uno eliminado durante el proceso y esta compensacion se hace considerando las ramas que finalmente resultaron conectadas a dicho nodo. El algoritmo utiliza los voltajes obtenidos en el caso base original para calcular las potencias complejas de salida de cada una de las ramas que conectan al nodo que se compensa. Las sumatorias de potencias resultantes son los ajustes al caso base reducido. El modelo de equivalentes propuesto permite el analisis de contingencias en puntos donde los equivalentes tradicionales no

STAND-ALONE WIND ENERGY CONVERSION SYSTEM WITH MAXIMUM POWER TRANSFER CONTROL SISTEMA AISLADO DE CONVERSIÓN EÓLICA CON CONTROL DE MÁXIMA TRANSFERENCIA DE POTENCIA

Directory of Open Access Journals (Sweden)

Miguel López

2009-12-01

Full Text Available A controlled wind generation system for a stand alone application is presented in this paper. A cascaded step-up/step-down power electronic converters topology is proposed to control the wind power system in the whole wind speed range. For the low wind speed range, the control strategy is aimed to follow the wind turbine’s maximal power coefficient by adjusting the generator’s rotational speed. For high wind speeds, the system power regulation is also made by controlling the generator speed. This control is made by the DC/DC power electronic converter, which modifies its input voltage, changing the machine voltage and consequently varying the generator’s rotor speed. The proposed system is validated by computer simulation. The proposed control system shows a good performance for its application in autonomous wind energy systems.Un sistema de generación eólica para una aplicación aislada es presentado en este artículo. Una topología de convertidores electrónicos de potencia elevador y reductor conectados en cascada es propuesta para controlar la producción eólica en todo el rango de velocidades del viento. Para el rango de vientos suaves, la estrategia de control permite seguir el máximo coeficiente de potencia de turbina eólica mediante el ajuste de la velocidad de rotación del generador. En el rango de vientos fuertes, la regulación de la potencia del sistema se hace igualmente por control de la velocidad de giro del generador. La acción de control es realizada mediante el convertidor DC/DC de potencia el cual modifica su tensión de entrada, cambiando así la tensión en los terminales de la máquina y por consecuencia variando la velocidad de rotación del generador. El sistema propuesto es validado mediante simulación por computador. Los resultados muestran que el sistema de control propuesto actúa de buena manera para su aplicación en sistemas autónomos de generación eólica.

Determinar estos valores a diferentes cargas, es la base para programas ahorro en la industria y los servicios. En este trabajo se presentan procedimientos para la estimación del factor de potencia y la eficiencia a cargas parciales, con una precisión acorde a los propósitos ingenieriles, baja invasividad y sin implicar para el usuario complejidades de equipamiento o de adquisición y procesamiento de datos. Se ofrecen distintas variantes para la estimación del factor de potencia y la eficiencia, según los datos con que se cuente. Se comparan los resultados de los métodos propuestos con la información de catálogos comerciales. Se realiza un análisis con motores de distinta potencia y velocidad, que demuestra que se logra buena precisión para los propósitos señalados. Three phase induction motors are rarely operating at full load and, in consequence, power factor and efficiency are affected. Determining these values for different partial loads is needed for energy saving programs in industrial and service enterprises. In this work, procedures are given for power factor and efficiency estimation at different loads. These procedures are low or not-invasive, have a good precision for engineering purposes, and do not require neither complex equipment nor complicated acquisition and processing data systems Different ways for estimating the before mentioned parameters, depending on the known data, are given. The results of the proposed procedures are compared with those of manufacturer catalogs. A comparative analysis considering motors of different output power and speed is done, and it shows that the results are enough accurate for the established purposes.

2009-01-01

The influence that grandparents have on the life history traits of their descendants has been studied extensively. However, no attention has been paid to the potential influence a grandparent's own reproductive history has on the investment they make in their grandchildren. We use data from 658 Swiss grandchildren and 591 of their grandparents to investigate whether grandparents' reproductive scheduling and family size influence the amount of investment grandparents make in a focal grandchild (shared contacts, occasions to meet, activities, discussions, interests, and important roles the grandparent plays). Grandparents who were younger when they had their first child had more children and grandchildren; this relationship strengthened after controlling for grandparental age, sex, lineage, and education (all P children or grandchildren was associated with reduced levels of grandparental investment. After adjustment for a wide range of factors known to influence investment, having more children or grandchildren and having a first child or grandchild at a younger age were associated with reduced investment in 14 of 24 analyses (all P family size. Interestingly, these relationships were only present in data reported from the grandchild's point of view, not the grandparent's. This analysis provides preliminary evidence that grandparents' reproductive strategies have consequences for the amount of investment they make in their grandchildren. These results are examined in terms of the trade-offs between current and future reproduction and offspring quality and quantity. 2009 Wiley-Liss, Inc.

Full Text Available This study aims to explore the reasons for the ineffectiveness of tax holiday policy implementation in Indonesia as well as the government’s strategies to improve the investment climate. This research uses exploratory study type which does not test theory or hypothesis by using preliminary survey method, conducting direct or indirect interview via e-mail to certain informant by giving questionnaire and direct observation passively observing the field and related websites supporting statistical data in this study in depth. In testing the validity of research data used source triangulation and method triangulation. The progress that has been achieved to date in the implementation of tax holiday policy is to provide ease of bureaucracy administration and simplicity of licensing services in investing by improving coordination among government to improve foreign investors' confidence when investing in Indonesia. So technically, the implementation of tax holiday policy is quite effective in attracting foreign direct investment because it can perform the right obligations according to the regulations. In the investment point of view, tax holiday policy is not effective in attracting foreign direct investment or not becoming the main factor of investor's goal in investment. The cause of the ineffectiveness of the tax holiday policy in attracting foreign direct investment in Indonesia is another indicator that becomes an assessment among others the ease of investment licensing, infrastructure, electricity supply, investor protection, minority and tax administration. Indonesian government's strategy to improve the investment climate is through deregulation, debureaucracy, law enforcement and business certainty for investors.

Investment Decision Support for Engineering Projects Based on Risk Correlation Analysis

Directory of Open Access Journals (Sweden)

Yan Liu

2012-01-01

Full Text Available Investment decisions are usually made on the basis of the subjective judgments of experts subjected to the information gap during the preliminary stages of a project. As a consequence, a series of errors in risk prediction and/or decision-making will be generated leading to out of control investment and project failure. In this paper, the variable fuzzy set theory and intelligent algorithms integrated with case-based reasoning are presented. The proposed algorithm manages the numerous fuzzy concepts and variable factors of a project and also sets up the decision-making process in accordance with past cases and experiences. Furthermore, it decreases the calculation difficulty and reduces the decision-making reaction time. Three types of risk correlations combined with different characteristics of engineering projects are summarized, and each of these correlations is expounded at the project investment decision-making stage. Quantitative and qualitative change theories of variable fuzzy sets are also addressed for investment risk warning. The approach presented in this paper enables the risk analysis in a simple and intuitive manner and realizes the integration of objective and subjective risk assessments within the decision-makers' risk expectation.

Luis David Avendaño Valencia

2007-09-01

Full Text Available En este artículo se presenta el desarrollo de un filtro para la reducción de la interferencia de línea de potencia en señales electrocardiográficas (ECG, basado en estimación dual de parámetros y de estado, empleando la filtración Kalman, en el cual se consideran modelos independientes entre la interferencia de línea de potencia y la señal ECG. Ambos modelos son combinados para simular la señal ECG medida sobre la que se realiza la estimación de estado para separar la señal de la interferencia. El algoritmo propuesto es sintonizado y comparado en un conjunto de pruebas realizadas sobre la base de datos QT de electrocardiografía. Inicialmente se hacen pruebas de sintonización del algoritmo para el rastreo de la señal ECG limpia, cuyos resultados son utilizados después para las pruebas de filtrado. Luego se llevan a cabo pruebas exhaustivas sobre la base de datos QT en la filtración de interferencia de línea de potencia, la cual ha sido introducida artificialmente en los registros, para una relación de señal a ruido (SNR dada, obteniendo así curvas del desempeño del algoritmo, que permiten a su vez comparar con el desempeño de otros algoritmos de filtración, a saber, un filtro notch recursivo de respuesta infinita al impulso (IIR y un filtro de Kalman, basado en un modelo más simple para la señal ECG. Como resultado, se demuestra que el algoritmo de filtrado obtenido es robusto a los cambios de amplitud de la interferencia; además, conserva sus propiedades para los diferentes tipos de morfologías de señales ECG normales y patológicas.

Evaluation and tuning of control algorithms for power system stabilizers; Evaluacion y sintonizacion de algoritmos de control para el estabilizador de sistemas de potencia

Energy Technology Data Exchange (ETDEWEB)

Ramirez Gonzalez, Miguel

1998-08-01

A procedure based on the phase compensation technique for tuning satisfactorily lead-lag power system stabilizers (PSS) is presented in this work. This procedure can be applied to standard models of PSS`s (with two phase compensation stages) where rotor speed deviation or an equivalent rotor speed signal is used as input. An analysis of several state of the art advanced control schemes is also presented, which are proposed for overcoming the limitations of conventional fixed parameters PSS`s. The advantages and drawbacks in designing certain types of PSS`s which are based on adaptive control, fuzzy logic and neural networks techniques are investigated. Based on this study, and taking into account the highly complex and non-linear nature of power systems, a fuzzy logic PSS is designed. In order to have good damping characteristics, speed deviation ({Delta}{omega}) of a machine and its acceleration ({Delta}{omega}) are chosen as the input signals to the fuzzy stabilizer of that particular machine. The performance of the lead-lag PSS and fuzzy stabilizer are validated through the simulation of two case studies: a single machine-infinite bus system, and a multimachine power system. All simulations were performed using a tool based on algorithms developed in MATLAB for the study of power system stability. [Espanol] Se presenta un procedimiento basado en la tecnica de compensacion de fase para ajustar en forma satisfactoria los parametros de los estabilizadores de sistemas de potencia (ESP) del tipo de adelanto-atraso. Este procedimiento es aplicable a modelos estandar de ESP`s (con dos redes de compensacion de fase) que utilizan como senal de entrada la velocidad del rotor del generador en cuestion, o una senal de velocidad equivalente. Por otra parte, se realiza un estudio de diversos esquemas de control avanzado del ESP que se proponen en la literatura actual para superar las limitantes de los estabilizadores convencionales. Basicamente, se analizan las ventajas y

The model was robust, addressing concerns about multivariate assumptions and other measures on the goodness of fit. It was found that the number of natural resources of economic importance plays a large role in the GDP performance. Thus, the preliminary symptom of Dutch disease continues to manifest for as long as each country aims for development, with their resources as ultimate enticing factors for foreign direct investment (FDI. In addition, economic growth is so far observed to be associated with the vulnerability of the country to climate change. Finally, economic growth was found to be linked to the negative impacts argued by the dependency theory. Implication on governance was discussed.

Full Text Available The article studies investment strategy and efficiency of investment activity of European insurance companies. In particular, it analyses the share of investments of insurance companies of Europe in GDP, investment portfolio of European insurers and its structure, contribution of insurance companies – leaders of investment activity – into the European investment portfolio. It studies influence of the financial crisis upon investment strategy of European insurers and analyses efficiency of investment activity of European insurers in risk insurance and life insurance. The article proves that investment business models of insurance companies are capable of resisting crisis phenomena more efficiently than other financial institutions. It marks out that measures of insurance companies that are directed at increase of profitability of investments require from them both significant expenditures on creation of the system of investment risk management and open access to different categories of financial assets and markets, which influences the general risk level, taken upon by an insurance company. The author draws a conclusion that, taking into account recent developments, European insurers should focus on equity and investment risk management, finding new possibilities for their (investments growth and also adaptation of new systems and operations for solution of these important tasks.

Investors are a heterogeneous group, they may be large or small, rich or poor, expert or lay man and not all investors need equal degree of protection (Mayya, 1996). An investor has three objectives while investing his money, namely safety of invested money, liquidity position of invested money and return on investment. The return on investment may further be divided into capital gain and the rate of return on investment as interest or dividend. Among all investment options available, securities are considered the most challenging as well as rewarding. Securities include shares, debentures, derivatives, units of mutual funds, Government securities etc. An investor may be an individual or corporate legal entity investing funds with a view to derive maximum economic advantage from investment such as rate of return, capital appreciation, marketability, tax advantage and convenience of investment.The Capital market facilitates mobilization of savings of individuals and pools them into reservoir of capital which can be used for the economic development of a country. An efficient capital market is essential for raising capital by the corporate sector of the economy and for the protection of the interest of investors in corporate securities. There arises a need to strike a balance between raising of capital for economic development on one side and protection of investors on the other. Unless the interests of investors are protected, raising of capital, by corporates is not possible. Like, the primary objective of a senior citizenís asset allocation is the generation of regular income.

Foreign Direct Investment versus Portfolio Investment : A Global Games Approach

OpenAIRE

Yamin Ahmad; Pietro Cova; Rodrigo Harrison

2004-01-01

We present a model of investment under uncertainty about fundamentals, using a global games approach. Goldstein & Razin (2003) show that there is an information based trade-off between foreign direct investment (FDI) and portfolio investment (PI) which rationalizes some well known stylised facts in the literature - the relative volatility and reversibility of foreign direct investment versus portfolio investment. We extend their result and show that uncertainty about fundamentals does not imp...

Investments in the Quebec energy sector: Increase of 27% in 1991 and forecast rise of 9% in 1992

International Nuclear Information System (INIS)

Anon.

1992-01-01

A compilation is presented of the sums invested in 1991 and the projected investments for 1992 in the Quebec energy sector. Historical data back to 1982 are also included. In 1991, the total investment rose to $4,328 million, or 27% more than in 1990. The year 1992 is expected to see a more modest 9% increase in energy investments. The relative value of energy investments compared to total Quebec investments was 15.6% in 1991 and is forecast to attain 16.9% in 1992. The large increase in energy investment is largely due to investments in the electric power sector, which receives ca 93% of Quebec energy investment. In the petroleum sector, preliminary data indicate that total investment in 1991 and 1992 will be $192.5 million and $203.1 million respectively, mostly for refining and distribution. In the natural gas sector, the historical data show a large peak at 1983 of $424 million, descending to the $50-70 million level starting in 1987. Natural gas investments in 1991 rose to $101.6 million, most of which went towards extending the distribution network. For 1992, $68.5 million is forecast to be invested. In the electric power sector, total 1991 investment was ca $4 billion, a 29% increase over 1990; 1992 investment is forecast at $4.46 billion. In 1991, the investment in electricity production totalled ca $2 billion and investment in power transmission $970 million, the latter mainly dedicated to construction of a 450 kV dc power line and to a network improvement program. Investment in power distribution was $567 million, while other investments such as communications, buildings, and technological activities amounted to $450 million. 4 figs., 5 tabs

Antonio Martínez-García

2005-03-01

Full Text Available Las producciones de régimen continuo, como las empresas de níquel, requieren del trabajo estable de los Sistemas Eléctricos de Potencia (SEP frente a las averías, por lo que la instalación de protecciones que actúen u operen solo cuando éstas ocurran, desconectando rápidamente la zona o equipo averiado, se hace necesaria para evitar la propagación del daño por todo el SEP. El funcionamiento inadecuado de las protecciones incrementa los costos de producción en una industria; para garantizar el buen funcionamiento de las mismas se requieren herramientas como los simuladores digitales de protección. Este artículo trata de la modelación y simulación de las protecciones eléctricas que utilizan los transformadores de potencia en dos industrias niqueleras cubanas. Mediante el empleo de una Biblioteca Virtual de Protecciones Eléctricas creada en MATLAB/SIMULINK, se analiza el comportamiento de los sistemas de protecciones instalados en ambas industrias, se detectan deficiencias y se ofrecen las soluciones adecuadas para evitar tanto el aumento de los costos de mantenimiento como las desconexiones inoportunas u operaciones incorrectas.

The Architecture of Investment Climate Surveillance and the Space for Non- Orthodox Policy

Directory of Open Access Journals (Sweden)

Håvard Haarstad

2012-03-01

Full Text Available The purpose of this article is to take preliminary steps towards a critical theory of what is termed an ‘architecture of investment climate surveillance’. The paper outlines the contours of this architecture, which it suggests is made up of various private and publicagents that have authoritative positions in the market for evaluating investment opportunities and risks. By way of illustrating basic linkages and mechanisms, it examines the way in which these agents ‘read’ the implementation of a piece of non-orthodox policy: Bolivia’s nationalisation of gas. Though not unproblematic, Bolivia’s policy of nationalisation has significantly increased state revenue and allowed new social spending on poverty reduction. Yet despite these positive developmental effects, readings of this policy shift within the investment community have been highly critical, illustrating the investor-centred values on which these evaluations are based. The article concludes bysuggesting that scholars of globalisation must pay more attention to whether and how such discursive responses are able to delimit the space for non-orthodox policy in the global South.

GREEN INVESTMENT: A STRATEGY FOR SUSTAINABLE ECONOMIC GROWTH AND INVESTMENT

Directory of Open Access Journals (Sweden)

Jaya Shukla

2014-01-01

Full Text Available Sustainable economic development has become an important area of concern due to climatic change with its long term effects. Climatic change has posed several challenges for economic sustainability of economies. Now major development projects have to comply with international environmental norms. Failure to do so may result in the delay of a project, fines including penalties for environmental damage or charges for remedial action, that affect the viability of a project or the value of any security taken. This paper investigates with help of secondary date using descriptive statistical technique opportunities and challenges of green investment. Here it is developed into suitable model for developing economies for successfully adopting green investment without much cost to their economies. The paper concludes that green investment involving direct investment and portfolio investment in firms adopting and following environmental protection norms will lead to sustainable growth and investment for economy.

Methodology The work is based on a studying of the practice of investments in structured investment products, detection and investigation of sources of market risk of structured investment products. Results Structured investment products, as any other investment product, has a significant set of risks that could affect to a large extent on its evaluation and determine the behavior of the investor. Financial engineers have the ability to control most of these risks, as well as to limit their impact. Thus, the structured investment product, unlike most classic investment instruments can provide investors with highly transparent mechanism to determining the ratio of investment risk and potential income. Practical implications The results can be used in a scientific investigation of the phenomenon of structured investment products, as well as practical work on the formation of the structured products by investment banks and brokerage firms.

Full Text Available En el paradigma actual de la cosmología, el modelo que goza de mayor aceptación, dadas las pruebas observacionales, es conocido co- mo ΛCDM (Cosmic Microwave Background. Este modelo está dominado principalmente por dos constituyentes de los cuales la física sabe muy poco de ellos. La energía oscura, con un 70 %, es la principal componente y la causante de la expansión acelerada del Universo, mientras que la materia oscura, con un 25 % aproximadamente, es la componente principal de las estructuras auto-gravitantes. En mucho menos proporción se tiene la com- ponente bariónica, la principal constituyente de las estrellas y por ende de la parte luminosa de las galaxias. Otras especies con menor proporción son las constituyentes relativistas entre las cuales se tienen los neutrinos y fotones. Después del periodo de expansión acelerada del universo, de- nominado periodo inflacionario, debido a las altas temperaturas el plasma primordial constituído de especies relativistas fué el componente dominante en el Universo. En dicho plasma, la materia bariónica se encuentra ionizada y se acopla a la radiación via dispersión de Compton. Tal plasma caliente desarrolla inestabilidades manifiestas en ondas de sonido y rarefacciones. Estas perturbaciones son soportadas hasta cuando el Universo en su ex- pansión se ha enfriado lo suficiente para formar materia neutra. Después de esta recombinación, la radiación se desacopla formando el mar de fotones de CMB. Junto con perturbaciones métricas colocadas por inflación en el potencial de la materia oscura, las oscilaciones del plasma quedaron im- presas tanto en la temperatura de CMB como en el espectro de potencias de materia. Aquí se muestra como el Weak Lensing puede ser usado para estudiar estas oscilaciones.

Development and application of a methodology for the classification of the operating conditions of power transformers; Desarrollo y aplicacion de una metodologia para la clasificacion del estado operativo de transformadores de potencia

Energy Technology Data Exchange (ETDEWEB)

Lara Covarrubias, Hector

2004-05-15

This thesis work shows the development of a classification model that allows the user to assess the operative condition of power transformers. The proposed model includes the following steps: Relative weights assignation for each IEEE-62-1995 required test. Those relative weights are obtained from test results and standardized and experience based limits obtained by Comision Federal de Electricidad (CFE). Once the relative weights have been assigned, three states, green, yellow and red were defined. Each state was then ranked with a weight number (1, 2 or 3). Specific weights were assigned for each test included in the model. Test score assignation takes into account the product of the relative value and the specific weight of each test. Transformer risk assessment uses the total score obtained from the sum of the tests partial scores. Transformer risk assessment was then classified in three categories. Total score causes the system to issue maintenance or substitution recommendations. The described model will improve maintenance scheduling according the transformer risk assessment and it is fully applicable to the complete CFE power transformer population. Further, smart investment and substitution plans, can be easily obtained from the model, preventing catastrophic failures that may cause logistic and economical problems to the Mexican Power System operation. As an example, the results obtained from the model application to two transformer banks installed in a CFE hydroelectric power plant were discussed and analyzed.

2009-01-01

Parametric cost models are routinely used to plan missions, compare concepts and justify technology investments. However, great care is required. Some space telescope cost models, such as those based only on mass, lack sufficient detail to support such analysis and may lead to inaccurate conclusions. Similarly, using ground based telescope models which include the dome cost will also lead to inaccurate conclusions. This paper reviews current and historical models. Then, based on data from 22 different NASA space telescopes, this paper tests those models and presents preliminary analysis of single and multi-variable space telescope cost models.

Fuzzy controller of speed-power of a synchronous micro generator; Controlador difuso de velocidad-potencia de un microgenerador sincrono

Energy Technology Data Exchange (ETDEWEB)

Martinez Alvarado, Raziel

2002-11-01

This thesis shows the design and implementation of a speed-power fuzzy-logic controller. The controller implementation was carried out on the Schrage motor-synchronous generator set. The synchronous alternator is rated 7 kVA, 220 V, 1800 rpm, 60 Hz. Two PI like fuzzy-logic controllers were developed with 9 and 25 rules. The controllers use the speed or power error and its integral as input variables and as an output the control signal from the brush-positioner of the Schrage motor. At the controller design stage, the anfis (adaptive-network-based fuzzy inference system) learning and structure procedure was used for tuning up parameters of the membership functions used on the designed fuzzy controllers. These controllers are first-order Sugeno-type. The designed controllers were tested on the motor-generator set under loaded and no-loaded conditions. It was found that PI-9 rules fuzzy-logic controller had better performance on both operating conditions. [Spanish] En este trabajo de tesis se presenta el diseno e implementacion de un controlador difuso de velocidad-potencia, para un grupo motor Schrage-generador sincrono de 7 kVA, 220 V, 1800 rpm, 60 Hz.

INVESTMENT FUNDS IN ROMANIA

COPIL CRINA ANGELA

2013-07-01

Full Text Available I chose this topic because my goal was to capture in detail all aspects of the evolution of investment funds under the influence of factors leading to globalization of the banking financial market. Main motivation was that I proposed to present in an original manner the concept of investment in mutual funds by the thoroughness of the following points: the different types of investment funds from Romania, the advantages, the risks and the specific costs of the investment in mutual funds and the effects of the financial crisis on the industry of the investment funds on the national level. The financial crisis and the risk of infecting the global economy affected the taste of risk of the investors and their request for the investment fund, determining the orientation of the investors to the funds with a lower risk – the diversified funds, the funds of bonds and the monetary funds. I considered important the theoretical approach of the concept of investments in investment funds because they are a barometer of the macro economical stability, in case the economical increase is positive on the macro economical level the investments in investments funds are increasing too. In Romania the market of the mutual funds is at an incipient level, but with potential and perspectives of development. Due to the bankruptcy of FNI in the beginning of the years 2000 and due to the absence of a clear legislation regarding the calculation of the unitary value of the net asset and the control of the activity developed by the investment funds, the development of the industry of the investment funds had to fight against the crisis of credibility generated by these events. The convergence of the Romanian economy to the European standards will attract also a modification of the structure of the financial investments of the individuals, by an increase of the investments in funds. In the world the investment funds are preferred by the investors for their advantages

Full Text Available The actual deficiency of investment into Russian industry innovative development increases its technological drag from industries of countries with developed markets. Although the rate of investment into real sectors of Russian economics mid 2000 was higher compared to the previous period, annual investment amounts were much lower than in 1990. At present, highest investment amounts are directed to industry extractive branches and to the commerce. Amounts invested to various economy branches do not correspond to their contribution to the country’sGross Added Product; particularly underinvested are manufacturing industry branches. At present, foreign share in the country economy total investment makes 15–18%. Recently, most interesting for foreigners was investment to machine-building branches with overwhelming part (for example, 90% in 2007–2008 of foreign investment into the machine-building industry being directed to creation of new automobile plants. Today, first place in the list of foreign investors’ preferences in Russia is taken by the machine-tool construction sector.

A severe collapse of fixed capital formation distinguished the onset of the Great Depression from other investment downturns between the world wars. Using a model estimated for the years 1890-2000, we show that the expected profitability of capital measured by Tobin's q, and the uncertainty...... surrounding expected profits indicated by share price volatility, were the chief influences on investment levels, and that heightened share price volatility played the dominant role in the crucial investment collapse in 1930. Investment did not simply follow the downward course of income at the onset...

Full Text Available Theoretical and empirical studies have focused on discretionary investments such as research and development (R&D and advertisement as value-creating activities. This empirical research article examines the determinants of the discretionary investment policy of food sector firms in India. The study aims to analyze the impact of financial policies and firm characteristics on the discretionary investment strategy of the food industry firms. The article uses the partial least squares structural equation modeling (PLS-SEM to understand the drivers of discretionary investment policy of food sector firms. The study finds that investment policy of firms is a major determinant of profitability of food sector firms. Higher investments in capital expenditures and working capital result in higher profitability. Management efficiency significantly influences firm profitability. The results suggest that riskier firms in food sector might focus on R&D investments as a strategy to generate more cash flows. Size of firm is negatively related to R&D intensity. Smaller firms in food sector tend to invest more in R&D. The study does not provide evidence to suggest that profitable firms invest more in R&D activities.

Full Text Available The present article aims to analyze the recent behavior of real exchange rate in Brazil and its effects over investment per worker in Brazilian manufacturing and extractive industry. Preliminary estimates presented in the article shows an over-valuation of 48% of real exchange rate in Brazil. The reaction between the level (and volatility of real exchange rate and investment (per worker in Brazil is analyzed by means of a panel data econometric model for 30 sectors of Brazilian manufacturing and extractive industry. The empirical results show that the level and volatility of real exchange rate has a strong effect over investment per worker in Brazilian industry. Finally, we conclude the article presenting a proposal for a new macroeconomic regime that aims to produce an acceleration of economic growth of Brazilian economy and, by that, a catching-up process with developed countries.

Minimal investment risk of a portfolio optimization problem with budget and investment concentration constraints

Science.gov (United States)

Shinzato, Takashi

2017-02-01

In the present paper, the minimal investment risk for a portfolio optimization problem with imposed budget and investment concentration constraints is considered using replica analysis. Since the minimal investment risk is influenced by the investment concentration constraint (as well as the budget constraint), it is intuitive that the minimal investment risk for the problem with an investment concentration constraint can be larger than that without the constraint (that is, with only the budget constraint). Moreover, a numerical experiment shows the effectiveness of our proposed analysis. In contrast, the standard operations research approach failed to identify accurately the minimal investment risk of the portfolio optimization problem.

In the present thesis work the application of identification techniques is investigated based on methods of spectral analysis to the study of the instantaneous characteristics of signals obtained by means of digital simulation of the dynamic behavior of the power system. The study focuses on the perspectives developed from two different approaches of analysis: the use of lineal methods of spectral analysis and the use of methods of non-lineal analysis, based on the concept of an analytical signal. The developed tools are applied to the study of two phenomena of electromechanical origin of different characteristics in complex power systems. A comparison between the results obtained is performed for these techniques and the possibility of its application is discussed for the problem of on-line identification in power systems.

[Are investment activity and backlog in investments risks for university medicine in Germany?].

Science.gov (United States)

Amann, I; Heyder, R; Strehl, R

2009-08-01

University medicine in Germany requires significantly higher funding and investment because its tasks not only include health care but also research and teaching. However, over recent decades less and less funding compared to the development of the turnover has been available. This trend is due to decreasing public funding. The diminishing funding has caused a major backlog of investment at German university hospitals. The first part of the article summarizes the investments policies at university hospitals and other hospitals. The second part describes the investment needs in university medicine and exposes risk factors for research, education and health care due to the process of investment planning and realization. Goal-oriented solutions are shown to facilitate investments. The third part discusses several risks caused by insufficient investments in university medicine. There are special risks for research, teaching, and the capacity for innovation in university medicine besides economical and medical risks. Some policies and financial strategies to overcome the backlog in investments are presented. After a summary, the article concludes with some practical examples of further measures to ensure sustainable funding.

Full Text Available The paper deals with the idea that investment process is important not only for the economic growth, but for the global integration. There is a powerful connection between FDI and domestic investments. As a result, the analysis is focused on FDI flows in EU28 and Euro area. The comparative analysis is followed by regression, in order to point out the disparities between Member States and their trend. The average value of inward and outward FDI flows is analysed using FDI intensity. A distinct part of the paper is focused on domestic investment process and analyses total investment, investment in construction and investment in equipment. The analysis is supported by the latest official statistical data, pertinent diagrams and tables. The main conclusion of the paper is that the economic crisis in Europe led to a decrease in FDI and domestic investment flows.

The deregulation and restructuring undergone by the electrical industry, as well as the tendency at world-wide level of reorganization in generation, transmission and distribution units has brought about, as a consequence, drastic changes in the operation of the electric power systems. The difficulties to construct new transmission power lines and the continuous increase in the electricity consumption are forcing more and more to operate the electric power systems every time nearer their safety limits. Nevertheless, to assure the system reliability without mattering what so plaintiff is the operating condition is a requirement that the electrical companies must satisfy. This panorama has motivated and impelled the use of new technologies for the critical indicators the monitoring that allow the electrical companies to guarantee the system safe operation. In this paper a methodology for the location of Fasorial Measurement Units, better known as FMU for the monitoring of the critical oscillation modes in the electric power systems is presented.

Investment in flood protection measures under climate change uncertainty. An investment decision

Energy Technology Data Exchange (ETDEWEB)

Bruin, Karianne de

2012-11-01

Recent river flooding in Europe has triggered debates among scientists and policymakers on future projections of flood frequency and the need for adaptive investments, such as flood protection measures. Because there exists uncertainty about the impact of climate change of flood risk, such investments require a careful analysis of expected benefits and costs. The objective of this paper is to show how climate change uncertainty affects the decision to invest in flood protection measures. We develop a model that simulates optimal decision making in flood protection, it incorporates flexible timing of investment decisions and scientific uncertainty on the extent of climate change impacts. This model allows decision-makers to cope with the uncertain impacts of climate change on the frequency and damage of river flood events and minimises the risk of under- or over-investment. One of the innovative elements is that we explicitly distinguish between structural and non-structural flood protection measures. Our results show that the optimal investment decision today depends strongly on the cost structure of the adaptation measures and the discount rate, especially the ratio of fixed and weighted annual costs of the measures. A higher level of annual flood damage and later resolution of uncertainty in time increases the optimal investment. Furthermore, the optimal investment decision today is influenced by the possibility of the decision-maker to adjust his decision at a future moment in time.(auth)

Full Text Available Direct foreign investment is one of the most important economic variables in the world. Aspects related to international investment agreements are reaching an outstanding place in economic international diplomacy. Nowadays, in the multilateral level there is not an agreement regarding investment and therefore this study is focused on this particular type of agreement. In order to reach this objective this study shows, first of all, how different attempts have been developed to get a multicultural a agreement regarding investment, and to refuse the general opinion that says that exponential growth of foreign investment flows in recent years has given impulse to launch a multilateral investment agreement. Secondly, this study discusses about regulations related to foreign investment under current WTO regulations, such as investment, measure agreements, and service agreement. Then, it analyzes what has happened inside the WTO from the creation of the investment team at the Singapore Conference to the failed Conference in Cancun. Finally, it analyzes the main arguments against the multilateral agreement and the effects of future possible multilateral negotiations in investment and it ends with some recommendations and conclusions.

On the example of "Agrofirm Brusilov" depth analysis of the agricultural enterprises to evaluate of profitability, liquidity, solvency, financial stability, the timing of the return of invested funds and minimizing investment risks was conducted. To study methods of rating and system analysis were used. To justify the conditions of  increasing investment attractiveness farms method of scoring was used. It was established as a result of the use of integrated evaluation of the financial position one can see problem aspects of financial position of the company and develop measures to enhance liquidity, solvency, identify potential for raising the efficiency of company and prevention of financial crisis. The analysis of financial position showed that the management of the enterprise doesn’t  think  about  financial stability and solvency, does not understand the benefit of borrowed capital. Using research results in practice of agricultural enterprises allows us to give a real evaluation of investment attractiveness and justify ways to improve it. Key words: investments, investment attractiveness, potential business, financial position.

. [Spanish] El comportamiento dinamico de los sistemas de potencia es no lineal y es comprendido por diversos procesos en diferentes escalas de tiempo. El tamano y la complejidad de estos mecanismos han estimulado a la propuesta de metodos que reducen la dimension original preservando caracteristicas esenciales de la naturaleza del sistema. En esta investigacion, se propone un metodo analitico no lineal basado en la teoria de formas normales y tecnicas de perturbacion singular para el analisis de oscilaciones de gran amplitud. Este enfoque permite que el metodo de formas normales alcance su maxima capacidad proporcionando una metodologia general para su aplicacion en una amplia variedad de sistemas no lineales en los diversos campos de la investigacion. Basados en la teoria de formas normales de los sistemas dinamicos, se propone un modelo que preserva la estructura del sistema, las caracteristicas de la red y la carga. Aprovechando la separacion que existe entre la dinamica lenta y rapida, originada por las diferentes escalas de tiempo; una eficiente tecnica basada en perturbaciones singulares, es usada para obtener el comportamiento no lineal de los sistemas de potencia preservando exactamente la estructura de la red. Este metodo no requiere reduccion de ecuaciones por lo que se puede obtener informacion adicional de interes directamente de la red y de la dinamica de la carga del sistema de potencia. En este trabajo son desarrolladas expresiones analiticas que proporcionan una buena aproximacion al comportamiento real del sistema, y ademas se proponen tecnicas para interpretar estas soluciones en terminos de funciones modales para designar areas de control y ubicar dispositivos FACTS; asi tambien se desarrollan criterios para caracterizar los efectos de la red sobre el comportamiento no lineal del sistema. Los procedimientos desarrollados son probados en dos sistemas reales de potencia.

The book wants to show that ecologically oriented and socially responsible investment has so far been underrated as a criterion of choice for finance decisions. Environmental investment funds offer the chance to make important investments into the future and the development of new technologies and methods of production, provided the openness of their claim is appreciated which is to go for anything that will improve our environment. Such confidence in the positive forces of the market is adequately rewarded, as international examples show. Environmental investment funds are a form of finance management for far-sighted investors and who are committed to the environment. The author presents the bases of ethic-ecologically oriented fund investment, reports experience abroad, and gives a current overview of the situation, nationally and internationally, in this sector of the finance market.

Power plants investment decision-making in consideration of investment risk

International Nuclear Information System (INIS)

Oda, Junichiro; Matsuhashi, Ryuji; Yoshida, Yoshikuni; Takashima, Ryuta

2005-01-01

In this paper, we consider the investment risk of nuclear power plants using the real options approach. It is essential that the Japanese society evaluate the investment risk, because nuclear power plants are facing definite uncertainty and Japanese governments intend to promote and assist nuclear power plants through subsidies and policy actions. We assumed that the wholesale market prices of electricity constitute the definite uncertainty and that the wholesale market prices follow the geometric Brownian motion with drift. Using the Bellman equation and a lattice framework, we evaluated the value of investment opportunity, the value of equipment, and the critical prices that are optimal prices to invest in a nuclear power plant in the finite time horizon. This analysis shows that higher volatility of the wholesale market prices would give power companies lower incentive to construct electric power plants, particularly capital-intensive power plants. In order to deliberate and hold the Japanese governments accountable for the economics of nuclear power plants, multifaceted evaluation is needed. (author)

To observe the influence of different investing methods and mold cooling methods on pure titanium castings invested in the self-made investment, and to provide theoretic base for the development for the investment. The influence of investing methods (one-step investing method and two-step investing method) on castability and crown fit of titanium castings were investigated, and the influence of cooling methods on reaction layers, mechanical properties and crown fit of titanium castings were investigated. Both the investing methods exhibited good castability, but only the titanium full crowns by one-step investing method showed clinically acceptable fit. Although the quenching group showed thinner reaction layer(100 microm), lower strength and similar elongation rate, the titanium castings by bench cooling showed clinically acceptable full crown fit with 115 microm thick reaction layer as cast. The one-step investing method and the bench cooling are recommended for the self-made investment.

In order to meet the World's energy requirements for the next 30 years, 16 000 billion dollars will be necessary. Some 60% of this investment will go to the electricity sector and almost half of the total investment must be made in the developing countries. Where fossil fuels are concerned the bulk of the investments will a devoted to exploration and development activities. Transportation and distribution will account for 54 % of the investment in the electricity sector. The financing of these investments is currently the subject of various uncertainties. The conditions for access to resources will be decisive for the oil and gas sectors. The impact of liberalization in the countries of the OECD and the profitability of the investments in developing countries constitute the main challenges for the electricity sector. (authors)

Green investment: Trends and determinants

International Nuclear Information System (INIS)

Eyraud, Luc; Clements, Benedict; Wane, Abdoul

2013-01-01

This paper fills a gap in the macroeconomic literature on renewable sources of energy. It offers a definition of green investment and analyzes the trends and determinants of this investment over the last decade for 35 advanced and emerging countries. We use a new multi-country historical dataset and find that green investment has become a key driver of the energy sector and that its rapid growth is now mostly driven by China. Our econometric results suggest that green investment is boosted by economic growth, a sound financial system conducive to low interest rates, and high fuel prices. We also find that some policy interventions, such as the introduction of carbon pricing schemes or “feed-in-tariffs,” which require use of “green” energy, have a positive and significant impact on green investment. Other interventions, such as biofuel support, do not appear to be associated with higher green investment. - Highlights: • We offer a definition of green investment and review its trend since 2000. • We analyze its determinants from both theoretical and empirical perspectives. • Green investment is boosted by economic growth, interest rates, and fuel prices. • Feed-in-tariffs and carbon pricing schemes impact positively green investment

Financing investment in environmentally sound technologies: Foreign direct investment versus foreign debt finance

International Nuclear Information System (INIS)

Anyangah, Joshua Okeyo

2010-01-01

This paper develops a screening model to examine the relationship between alternative sources of private capital and investment in environmentally sound technologies (ESTs). In the model, a polluter (agent) must secure investment funds from the international financial markets in order to upgrade its production and abatement technology. The requisite capital can be obtained via either market loans (debt finance) or foreign direct investment (FDI). Under debt finance, the foreign financier supplies only capital and the relationship between the two parties is more 'arms-length'. By contrast, under FDI, the investor delivers both capital and managerial skills. We use the model to derive the implications of debt finance for optimal investment decisions and compare them to those obtained under FDI. Investment incentives are more pronounced under debt finance. (author)

To the interior of the Generation of Electrical Equipment (GEE) of the Instituto de Investigaciones Electricas, one of the main activities is the diagnosis of the electrical equipment in service. It is well known that the power equipment represents a strong investment that requires the guarantee that it has been manufactured, installed and operated satisfactorily. The life expectancy of these devices is of thirty years, however, many of them already have surpassed that expectation. The rehabilitation or substitution of the equipment implies new investments that are needed for an evaluation of the real condition of the equipment to carry out such rehabilitation. One of the tools necessary to carry out the diagnosis, is a movable laboratory that facilitates all the necessary tools to perform a meticulous analysis that would allow, the client, to make high cost decisions. The application of the movable laboratory is advisable from the inauguration of the equipment. The electrical mechanisms are factory tested in accordance with standardized protocols; it guarantees the fulfillment of the necessary requirements for a correct operation. Nevertheless, when taking them to the assembly site, these are subjected to a series of processes and mechanical stresses that could alter the equipment conditions and its integrity.

[Several problems concerning population investment].

Science.gov (United States)

Liu, Z

1982-07-29

Population investment is a major topic in the studies of population and economic relations. In this particular area, numerous theoretical and practical problems are still in need of solution. Concerning the problem of population concept, there are three different approaches: (1) to determine the definition of population investment from the relationship between the population growth and the capital from national income used for investment, including investment in the newly increased population and investment in the entire population; (2) to explain population investment from the economic viewpoint that people are producers; and (3) to explain population investment from the expense needed to change a simple labor force to a skillful labor force. The expenses include educational costs, maintanance spending, wages needed to compensate workers in labor, costs for workers to master and learn modern scientific techniques to be used for production, and the costs of keeping a young labor force in the next generation.

Considering barriers to investment in South Africa

Directory of Open Access Journals (Sweden)

KB Afful

2014-10-01

Full Text Available This paper examines the effect of South Africa’s economic fundamentals on net direct investment and net portfolio investment. The results suggest that the main determinants of investment in South Africa are resource prices, input productivity and the economic performance of the domestic economy. The results illustrate that net direct investment and net portfolio investment are close but not perfect substitutes. In addition, we find that an increase in labour input costs reduces both net direct investment and net portfolio investment. Further, an increase in fixed capital productivity increases net direct investment. Further, also the results illustrate that subsidies increase both net direct investment and net portfolio investment. Moreover, an increase in exports increases both net direct investment and net portfolio investment. Policy recommendations are thus proposed that may increase foreign direct investment in South Africa.

Competition in investment banking

Directory of Open Access Journals (Sweden)

Katrina Ellis

2011-01-01

Full Text Available We construct a comprehensive measure of overall investment banking competitiveness for follow-on offerings that aggregates the various dimensions of competition such as fees, pricing accuracy, analyst recommendations, distributional abilities, market making prowess, debt offering capabilities, and overall reputation. The measure allows us to incorporate trade-offs that investment banks may use in competing for new or established clients. We find that firms who switch to similar-quality underwriters enjoy more intense competition among investment banks which manifests in lower fees and more optimistic recommendations. Investment banks do compete vigorously for some clients, with the level of competition related to the likelihood of gaining or losing clients. Finally, investment banks not performing up to market norms are more likely to be dropped in the follow-on offering. In contrast, firms who seek a higher reputation underwriter face relatively non-competitive markets.

Essays in Investment Theory

International Nuclear Information System (INIS)

Bobtcheff, C.

2006-01-01

This thesis analyzes different aspects of the investment decision. In the first chapter, we consider an economy in which different energy sources may produce electricity. The model focuses first on the optimal use of a hydroelectric dam from which water can be extracted and which is supplied with a random water flow. The presence of constraints on a minimal and on a maximal storage capacity makes electricity consumption smoothing possible only when the quantity of water available to the agent lies in a certain range that we determine. In a second stage, we introduce a second energy source with unlimited supply at some exogenous cost. The marginal propensity to produce hydroelectricity is an increasing function of the second technology cost. The availability at a low cost of the alternative source improves thus time diversification. Finally, the optimal electric park is composed of a number of dams that is increasing with the cost of the second technology. Chapter 2 studies the decision of an investor who wants to undertake an irreversible investment when he has the choice between two mutually exclusive projects that present input price and/or output price uncertainty. We prove that the investor decides not to invest in any project when each investment generates the same payoff independently of its size. Therefore, some inaction region appears in which the investor prefers not to invest whereas an immediate investment would have been optimal if no choice had been available: a 'choice value' is thus created. A key feature of this bidimensional degree of uncertainty is thus that the payoff generated by each project is not a sufficient statistic to make a rational investment. In this context, our analysis provides a new motive for waiting to invest: the benefits associated with the dominance of one project over the other. In chapter 3, we study the investment decision problem of a duo-poly with price competition on a market of finite size driven by stochastic taste

VALUE-ADDED SERVICE INVESTING AND PRICING STRATEGIES FOR A TWO-SIDED PLATFORM UNDER INVESTING RESOURCE CONSTRAINT

Institute of Scientific and Technical Information of China (English)

Guowei Dou; Ping He

2017-01-01

Investing on value-added service (VAS) amplifies users' participation and platform profit.However,the investing resource is usually limited in practice.This paper investigates VAS investing and pricing strategies for a two-sided platform under investing resource constraint.We reveal that with VAS investment,Subsidizing can still be done to enlarge users' demand,even when the investing cost becomes higher.For optimal pricing strategies,the network effect will be the dominating determinant if the gap between two marginal cross-side benefits (i.e.the benefit that users obtain when each new user join the other side of the platform) is large.Interestingly,we show that with the increase of the marginal investing cost,users might either be priced higher or lower.If the marginal investing cost increases to a high level,and the gap between the two marginal cross-side benefits is large,lowering the access fee for users possessing the higher cross-side network effect does not necessarily compensate more profit loss caused by higher cost.Moreover,after VAS is developed,raising the access fee for those whose marginal investing benefit is large does not necessarily generate more profit as well.The opposite strategy further enlarges users' utility,and promotes the investment to benefit more users.

Real Options Analysis of Electricity Investments

Energy Technology Data Exchange (ETDEWEB)

Heggedal, Ane Marte

2012-07-01

This thesis utilizes real options analysis for evaluating investment opportunities in the electricity sector. It also formally tests how investors in hydropower plants have included uncertainty when considering their investment opportunities. The real options method applies financial options theory to quantify the value of management flexibility and is chosen due to three important characteristics of investments in the electricity sector. First; the investment is completely or partially irreversible, second; the investor can choose when to invest in the facility, and third; there is uncertainty in several factors affecting the cash flows of the investments. Factors of uncertainty include the development of electricity prices, policies, technological advances, and macroeconomics measures.Four papers are included in this thesis. Paper 1, Upgrading hydropower plants with storage: Timing and capacity choice, presents a valuation framework for deciding when to upgrade an existing hydropower plant and which capacity to choose. The second paper, Transmission capacity between Norway and Germany: A real options analysis, sheds light on when two electricity markets, in this case Norway and Germany, should be connected through a sub sea cable. The investor can choose when to invest and the capacity of the cable, and may also choose to invest sequentially. Paper 3, Optimal timing and capacity choice for pumped hydropower storage, investigates when investment in a pumped hydropower plant with storage should be undertaken and what the capacity of the facility should be. Whereas the three first papers investigate investment opportunities, Paper 4, Uncertain climate policy decisions and investment timing: Evidence from small hydropower plants, studies when investors in small hydropower plants chose to invest. The analyses disclose whether the net present value approach or the real options method best describe the investment decisions made by the investors. Viewing investment

Full Text Available La regulación de la tensión es el modo más elemental de control de los Sistemas Eléctricos de Potencia que mejora la estabilidad y la estabilidad transitoria. La introducción de reguladores de tensión muy rápidos facilita la capacidad del sistema de generar acciones que conserven su estabilidad (incremento del torque sincronizante. No obstante, estos dispositivos disminuyen el amortiguamiento del sistema. La forma más económica de mejorar el amortiguamiento de las oscilaciones mecánicas de las unidades generadoras se logra con la adición de un control suplementario agregado en el sistema de excitación, que se conoce como estabilizador de potencia (PSS, por sus siglas en inglés Power System Stabilizer. En el presente trabajo se utilizan las posibilidades del paquete PSAT para seleccionar la mejor ubicación y ajustar PSS en un sistema longitudinal sencillo de dos áreas, similar al caso del Sistema Eléctrico de la República de Cuba. Normally, voltage regulation is the primary mode of control, which improves voltage and transient stability. The introduction of generator´s fast voltage regulators improves Electrical Power Systems ability to generate synchronizing torque to maintain stability. These control devices have a negative effect in damping system oscillations. Supplementary control in generator’s voltage regulators (PSS is the most economic solution to improve system damping. This supplementary control is obtained using power system dampers. PSAT abilities are used in order to obtain setting of this supplementary control in a simple longitudinal two areas system, similar to Cuban Electric Power System.

Chinese investments in the EU

Directory of Open Access Journals (Sweden)

Haico EBBERS

2010-12-01

Full Text Available China’s investments in the European Union are much lower than what you may expect given the economic size of both entities. These relatively low investments in Europe are a combination of priority and obstacles. The priority for investments is clearly in Asia, Africa and Latin America. This regional pattern is heavily influenced by the need to solve the resource shortage in the medium and long term. The investments in Europe and the United States are mostly market seeking investments. Research specifically focused on Chinese M&A abroad comes to the same conclusion. The success rate of Chinese M&A abroad is much lower than what we see with respect to American or European investments abroad. In this paper, we examine why Chinese firms are facing more difficulties in the European Union than in other regions. The paper focuses on Chinese M&A as proxy for total foreign direct investments abroad. By looking at the factors that have been documented as influencing the level of M&A abroad, it becomes clear that Chinese firms in Europe are hindered by many factors. For example, the trade between China and the EU is relatively low, the institutional quality is lower compared to the United States, there is less experience with respect to Europe and relatively many deals relate to State Owned Enterprises (SOE which makes the deal sensitive. So it is logical that Chinese investments are not very high in Europe. However, the research makes clear that the obstacles for Chinese investments in Europe are disappearing step by step. In that sense, we expect a strong increase of Chinese investments in Europe in the future.

Interaction between Dynamic Financing and Investments

DEFF Research Database (Denmark)

Dockner, Engelbert J.; Mæland, Jøril; Miltersen, Kristian R.

Debt priority rules, i.e., the rules determining how different classes of debt split the firm's assets after bankruptcy, influence the firm's investment decisions. Existing debt benefits from an investment either because the investment is equity financed or because new debt issued to (partly......) finance the investment has lower priority in the event of bankruptcy as is the case for the commonly used absolute priority rule (APR). This incentivizes equity holders to under invest. If debt priority rules are specified in such a way that existing debt can be exploited by issuing new debt, do equity...... holders have the incentive to over invest. We formulate a dynamic structural model to study the interaction of initial capital structure choice, investment policy, subsequent debt issues, and debt priority rules. We find that priority rules have a substantial impact on investment timing as well...

Investment, regulation, and uncertainty

As with any technological innovation, time refines the technology, improving upon the original version of the innovative product. The initial GM crops had single traits for either herbicide tolerance or insect resistance. Current varieties have both of these traits stacked together and in many cases other abiotic and biotic traits have also been stacked. This innovation requires investment. While this is relatively straight forward, certain conditions need to exist such that investments can be facilitated. The principle requirement for investment is that regulatory frameworks render consistent and timely decisions. If the certainty of regulatory outcomes weakens, the potential for changes in investment patterns increases.   This article provides a summary background to the leading plant breeding technologies that are either currently being used to develop new crop varieties or are in the pipeline to be applied to plant breeding within the next few years. Challenges for existing regulatory systems are highlighted. Utilizing an option value approach from investment literature, an assessment of uncertainty regarding the regulatory approval for these varying techniques is undertaken. This research highlights which technology development options have the greatest degree of uncertainty and hence, which ones might be expected to see an investment decline. PMID:24499745

Investing in river health.

Science.gov (United States)

Bennett, J

2002-01-01

Rivers provide society with numerous returns. These relate to both the passive and extractive uses of the resources embodied in river environments. Some returns are manifest in the form of financial gains whilst others are non-monetary. For instance, rivers are a source of monetary income for those who harvest their fish. The water flowing in rivers is extracted for drinking and to water crops and livestock that in turn yield monetary profits. However, rivers are also the source of non-monetary values arising from biological diversity. People who use them for recreation (picnicking, swimming, boating) also receive non-monetary returns. The use of rivers to yield these returns has had negative consequences. With extraction for financial return has come diminished water quantity and quality. The result has been a diminished capacity of rivers to yield (non-extractive) environmental returns and to continue to provide extractive values. A river is like any other asset. With use, the value of an asset depreciates because its productivity declines. In order to maintain the productive capacity of their assets, managers put aside from their profits depreciation reserves that can be invested in the repair or replacement of those assets. Society now faces a situation in which its river assets have depreciated in terms of their capacity to provide monetary and non-monetary returns. An investment in river "repair" is required. But, investment means that society gives up something now in order to achieve some benefit in the future. Society thus has to grapple wih the choice between investing in river health and other investments--such as in hospitals, schools, defence etc. - as well as between investing in river health and current consumption--such as on clothes, food, cars etc. A commonly used aid for investment decision making in the public sector is benefit cost analysis. However, its usefulness in tackling the river investment problem is restricted because it requires all

BRICS Investment Policies from PFI Perspective

Directory of Open Access Journals (Sweden)

Andrei Sakharov 

2017-12-01

Full Text Available The Organisation for Economic Co-operation and Development (OECD Policy Framework for Investment (PFI contains recommendations and best practices in 12 investment-related policy areas, and is widely regarded as the world’s most comprehensive and authoritative instrument on international investment regulation. The topicality of PFI recommendations for OECD members and other countries, including Russia, is dictated by competition in international investment markets. The instrument’s implementation can significantly boost a national jurisdiction’s attractiveness to investors and thus increase its economic competitiveness. The experience of the BRICS countries as large developing economies involved in collaboration with the OECD could be of great value from the standpoint of PFI implementation in Russia. This article examines investment policies of Brazil, India, China and South Africa from the perspective of PFI recommendations. The analysis is organized around four major themes: the general characteristics of investment regimes and investment stimuli, national investment regulation regimes, trade policies and overcoming structural limitations. The analysis forms the basis for recommendations to improve the investment policy regime in Russia

Energy investments and employment

International Nuclear Information System (INIS)

1993-08-01

A study was conducted to assess the effect that different energy options would have on provincial and regional employment prospects in British Columbia. Current and future economic and employment patterns were examined to develop a more detailed understanding of the skills, age, gender, location, and other characteristics of British Columbia workers. Over 40 previous studies examining the energy/employment relationship were also reviewed. Based on this review and an analysis of the province's economic and labor conditions, the following conclusions are drawn. Investment in non-energy sectors offers better prospects for reducing unemployment than investment in the energy sector, whether for new supply or improving efficiency. Investments in the energy sector provide fewer jobs than investments in most other sectors of the economy. Among the available electricity supply options, large hydroelectric projects tend to produce the fewest jobs per investment dollar. Smaller thermal projects such as wood residue plants produce the most jobs. If and when more energy is needed in British Columbia, the most cost-effective combination of energy supply and efficiency options will also create the most jobs. Compared to traditional energy supply options, investments in energy efficiency would create about twice as many total jobs, create jobs that better match the skills of the province's unemployed and its population distribution, and create jobs that last longer on the average. Construction-related measures such as improved insulation tend to produce more jobs per investment dollar than the substitution of more energy-efficient equipment. 69 refs., 9 tabs

The economic rationale for investing decisions innovative projects rationalization of investments for innovative projects

Full Text Available The article provides a selection of methods for determining the feasibility of an investment-innovative project. Estimated indicators are identified analytically, on their basis a conclusion is made about the economic efficiency and feasibility of the project, which is the basis of its competitiveness. Such growth analytics is necessary, since the social and economic development of the country and the region largely depends on the investment climate, which is facilitated by the legislation of the Russian Federation (the Tax Code of the Russian Federation, the law of the Russian Federation on the regulation of investment activities, etc.. Since competitiveness is also determined by the economic feasibility and financial solvency of innovative projects, modern information and software, as well as the methodology for project appraisal and the corresponding order of their implementation, are needed. In the Russian Federation, a method is used to assess the efficiency of capital investments in capitalist countries, as well as the methodology of economic (competitive analysis of investment-innovative projects. The basis of the method is that reimbursement of investments occurs in two economic forms: net profit and depreciation (net income. Of the numerous methods for assessing the feasibility of investment, the most often used along with discount methods (taking into account the factor of money changes over time, statistical methods with determining the payback period and the average rate of return on investment. Defined indicators: the net present value (NPV and the internal rate of return (IRR. The methodology specified in the article is useful to the investor in order to rationalize investment flows, helps to achieve the maximum IRR. The implementation of the innovative project serves the competitiveness of the manufacturing enterprise by increasing the technical and technological levels of the products.

A government's lack of credibility when promising future taxation and regulation of foreign direct investment is often regarded as an obstacle to foreign investment. As shown in this paper, the total lack of inter-period credibility may not necessarily prevent investments from taking place. Both the government and the investor can benefit from negotiating a series of short-lived agreements in which the investor obtains a share of the revenue generated from previous investments against the undertaking of making new investments. This assumes that intra-period agreements are respected by the parties

Preliminary design of a coffee harvester

Directory of Open Access Journals (Sweden)

Raphael Magalhães Gomes Moreira

2016-10-01

Full Text Available Design of an agricultural machine is a highly complex process due to interactions between the operator, machine, and environment. Mountain coffee plantations constitute an economic sector that requires huge investments for the development of agricultural machinery to improve the harvesting and post-harvesting processes and to overcome the scarcity of work forces in the fields. The aim of this study was to develop a preliminary design for a virtual prototype of a coffee fruit harvester. In this study, a project methodology was applied and adapted for the development of the following steps: project planning, informational design, conceptual design, and preliminary design. The construction of a morphological matrix made it possible to obtain a list of different mechanisms with specific functions. The union between these mechanisms resulted in variants, which were weighed to attribute scores for each selected criterion. From each designated proposal, two variants with the best scores were selected and this permitted the preparation of the preliminary design of both variants. The archetype was divided in two parts, namely the hydraulically articulated arms and the harvesting system that consisted of the vibration mechanism and the detachment mechanism. The proposed innovation involves the use of parallel rods, which were fixed in a plane and rectangular metal sheet. In this step, dimensions including a maximum length of 4.7 m, a minimum length of 3.3 m, and a total height of 2.15 m were identified based on the functioning of the harvester in relation to the coupling point of the tractor.

Oleinik Elena

2017-01-01

Full Text Available Modern conditions of economic systems development have necessitated more precise directions of investment process for the economic growth to accelerate. The precipitous fall of oil prices that occurred in the second half of 2014 weighed heavily on foreign direct investment flows to oilexporting countries. The problem of attracting investment is one of the key problems of economic development. The aim of this study is to analyze and evaluate the shifts in the structure of investments, the study of the structure of investments to the Russian economy. Structural changes result from differences in the growth rate of the elements forming an economic system. An integral coefficient has been used for evaluation of structural changes. Multiple regression was used to analyze the impact of various factors on the change in structure of investment. The regression coefficients in the model give quantitative assessment of the pace of change in the structure as it depends on a specific factor. The model estimation shows that the variables “share of investments in manufacturing” (positive influence and “share of investments in the health, physical culture, education” (negative influence have the largest t-values. Hence, these two factors influence the structural changes in investments most strongly The evaluation and analysis of the structural shifts may lead to conclusions regarding the efficiency of the structure investment and adjustment of the economic policy.

[Spanish] Se presenta un metodo para resolver el problema de asignacion de unidades termoelectricas en sistemas electricos de potencia de gran escala. El problema consiste en determinar cuales unidades generadoras deberan ser programadas para entrar o salir de operacion durante los intervalos de horizonte de planeacion, de tal forma que se satisfagan a minimo costo, y en forma confiable la demanda pronosticada de potencia electrica y las restricciones fisicas y operativas de los componentes del sistema de potencia. El metodo esta compuesto por dos etapas: la primera etapa encuentra una solucion inicial factible de unidades termo por medio de metodos heuristicos. La segunda etapa produce una solucion a partir de un estado de asignacion inicial factible. El costo de operacion se reduce aplicando programacion dinamica en aproximaciones sucesivas, de tal forma que el producto de cada interaccion constituye el estado de asignacion de menor costo encontrado hasta esa etapa. El rango de busqueda para la solucion optima es reducido aplicando tecnicas de relajacion lagrangeana para seleccionar unicamente las unidades que tienen el mayor potencial de reducir el costo de operacion. El algoritmo es validado utilizando un sistema representativo del sistema interconectado nacional que consta de 108 unidades termoelectricas agrupadas en 7 grupos de generacion, para un horizonte de planeacion de una semana dividido en intervalos horarios, conteniendo 18,144 variables discretas, 18,144 variables continuas y 39,024 restricciones.

Identifying options for regulating the coordination of network investments with investments in distributed electricity generation

International Nuclear Information System (INIS)

Nisten, E.

2010-02-01

The increase in the distributed generation of electricity, with wind turbines and solar panels, necessitates investments in the distribution network. The current tariff regulation in the Dutch electricity industry, with its ex post evaluation of the efficiency of investments and the frontier shift in the x-factor, delays these investments. In the unbundled electricity industry, the investments in the network need to be coordinated with those in the distributed generation of electricity to enable the DSOs to build enough network capacity. The current Dutch regulations do not provide for a sufficient information exchange between the generators and the system operators to coordinate the investments. This paper analyses these two effects of the Dutch regulation, and suggests improvements to the regulation of the network connection and transportation tariffs to allow for sufficient network capacity and coordination between the investments in the network and in the generation of electricity. These improvements include locally differentiated tariffs that increase with an increasing concentration of distributed generators.

What are community energy companies trying to accomplish? An empirical investigation of investment motives in the German case

International Nuclear Information System (INIS)

Holstenkamp, Lars; Kahla, Franziska

2016-01-01

Community energy has become an increasingly important issue in academia and in energy policy circles worldwide. Citizens jointly investing in and operating renewable energy installations have played an essential role in countries such as Germany or Denmark. Building on and extending previous studies, we collect survey data on investment motives for a stratified random sample of German community energy companies. Structural variables are selected using a socio-ecological-technical systems framework. This study aims to identify differences within the community energy sector to better understand investment behaviour and the effects of policy changes. Despite the small sample coverage at the individual member level, the preliminary results of this study suggest that, first, community energy forms a specific type of social investment and that, second, there are significant differences between community energy companies, especially regarding the assessment of the return motive. This motive plays a more prominent role in limited partnerships than in cooperatives and for community wind than for companies focusing on solar or biomass. While these and other factors are highly interrelated, our data indicate that the social setting and geographical and climatic conditions are the critical ones here. These findings may guide further research. - Highlights: • Community energy companies form a specific part of the impact investment sector. • Differences in the valuation of investments exist mainly regarding the return motive. • There are significant differences between North vs South and cooperatives vs LPs. • The return motive plays a higher role for community energy founded 2009–2011. • These differences have to be taken into account when assessing policy changes.

Evaluation methodology for flood damage reduction by preliminary water release from hydroelectric dams

Science.gov (United States)

Ando, T.; Kawasaki, A.; Koike, T.

2017-12-01

IPCC AR5 (2014) reported that rainfall in the middle latitudes of the Northern Hemisphere has been increasing since 1901, and it is claimed that warmer climate will increase the risk of floods. In contrast, world water demand is forecasted to exceed a sustainable supply by 40 percent by 2030. In order to avoid this expectable water shortage, securing new water resources has become an utmost challenge. However, flood risk prevention and the secure of water resources are contradictory. To solve this problem, we can use existing hydroelectric dams not only as energy resources but also for flood control. However, in case of Japan, hydroelectric dams take no responsibility for it, and benefits have not been discussed accrued by controlling flood by hydroelectric dams, namely by using preliminary water release from them. Therefore, our paper proposes methodology for assessing those benefits. This methodology has three stages as shown in Fig. 1. First, RRI model is used to model flood events, taking account of the probability of rainfall. Second, flood damage is calculated using assets in inundation areas multiplied by the inundation depths generated by that RRI model. Third, the losses stemming from preliminary water release are calculated, and adding them to flood damage, overall losses are calculated. We can evaluate the benefits by changing the volume of preliminary release. As a result, shown in Fig. 2, the use of hydroelectric dams to control flooding creates 20 billion Yen benefits, in the probability of three-day-ahead rainfall prediction of the assumed maximum rainfall in Oi River, in the Shizuoka Pref. of Japan. As the third priority in the Sendai Framework for Disaster Risk Reduction 2015-2030, `investing in disaster risk reduction for resilience - public and private investment in disaster risk prevention and reduction through structural and non-structural measures' was adopted. The accuracy of rainfall prediction is the key factor in maximizing the benefits

Full Text Available Global economy still records a decline in FDI. The main causes are increased economic instability and geopolitical risks. Given the continued negative trend, it is clear that it is necessary to reform the investment policies at the national, regional, bilateral, multilateral and international level, to ensure sustainable economic development. Key elements of the reforms are: to provide instruments to reduce risks, create mechanisms of responsible investment, improve the structural coherence and promote regional investments. Refer to the current dates of the sectors investments (according to the report of UNCTAD from 2015th shows that the services sector recorded double growth compared to the investment in the manufacturing sector in 2012. Also, if we take into consideration the fact that investment in IT sector investment involves three aspects: transactional (minimizing costs, strategic (innovation technologies, achieving competitiveness and information (improving access to information and communications, it may be assumed that the reforms in the investment policies should be directly correlated with investments in information technology.

LaCommare, Kristina [Lawrence Berkeley National Lab. (LBNL), Berkeley, CA (United States); Larsen, Peter [Lawrence Berkeley National Lab. (LBNL), Berkeley, CA (United States); Eto, Joseph [Lawrence Berkeley National Lab. (LBNL), Berkeley, CA (United States)

2017-01-01

Policymakers and regulatory agencies are expressing renewed interest in the reliability and resilience of the U.S. electric power system in large part due to growing recognition of the challenges posed by climate change, extreme weather events, and other emerging threats. Unfortunately, there has been little or no consolidated information in the public domain describing how public utility/service commission (PUC) staff evaluate the economics of proposed investments in the resilience of the power system. Having more consolidated information would give policymakers a better understanding of how different state regulatory entities across the U.S. make economic decisions pertaining to reliability/resiliency. To help address this, Lawrence Berkeley National Laboratory (LBNL) was tasked by the U.S. Department of Energy Office of Energy Policy and Systems Analysis (EPSA) to conduct an initial set of interviews with PUC staff to learn more about how proposed utility investments in reliability/resilience are being evaluated from an economics perspective. LBNL conducted structured interviews in late May-early June 2016 with staff from the following PUCs: Washington D.C. (DCPSC), Florida (FPSC), and California (CPUC).

Precommitted Investment Strategy versus Time-Consistent Investment Strategy for a Dual Risk Model

Directory of Open Access Journals (Sweden)

Lidong Zhang

2014-01-01

Full Text Available We are concerned with optimal investment strategy for a dual risk model. We assume that the company can invest into a risk-free asset and a risky asset. Short-selling and borrowing money are allowed. Due to lack of iterated-expectation property, the Bellman Optimization Principle does not hold. Thus we investigate the precommitted strategy and time-consistent strategy, respectively. We take three steps to derive the precommitted investment strategy. Furthermore, the time-consistent investment strategy is also obtained by solving the extended Hamilton-Jacobi-Bellman equations. We compare the precommitted strategy with time-consistent strategy and find that these different strategies have different advantages: the former can make value function maximized at the original time t=0 and the latter strategy is time-consistent for the whole time horizon. Finally, numerical analysis is presented for our results.

Full Text Available La masiva cantidad de datos biológicos provenientes de las disciplinas "ómicas" y su aprovechamiento en el mejoramiento genético vegetal requiere de nuevos abordajes teóricos y estadísticos que describan de forma satisfactoria principios generales en los genomas. El total de secuencias de los genes de los genomas vegetales de Arabidopsis thaliana y Oriza sativa y del genoma animal Mus musculus fueron extraídas y depuradas de la base de datos pública del Genebank mediante el diseño de algoritmos en lenguaje de programación Python. Se analizaron las distribuciones de las variables frecuencia de uso y tamaño de los genes, exones e intrones por cromosoma y entre genomas. Los resultados señalaron que las variables presentan patrones de comportamiento no lineales en forma de ley de potencia que difieren estadísticamente entre los genomas pero no entre los cromosomas de un mismo genoma. Además, el análisis aportó evidencias respecto al tamaño promedio constante de las secuencias de exones y de los genes simples por cromosoma y entre genomas. Los hallazgos sugieren: primero, que el genoma se auto-organiza de la misma manera en los cromosomas independientemente del tamaño o número de genes que estos contengan, y, segundo, que tanto los cromosomas como sus elementos constituyentes: genes, exones e intrones han evolucionado conjuntamente. El estudio señala que las leyes de potencia cumplen un papel amortiguador en las leyes de variación biológica y proporcionan medidas cuantitativas de la organización de las secuencias de ADN que definen la identidad de un genoma. La regularidad estadística de estas medidas genéticas tiene potenciales aplicaciones en el incremento del valor predictivo de los actuales modelos de mejoramiento genético vegetal.

Policy Uncertainty, Investment and Commitment Periods

Energy Technology Data Exchange (ETDEWEB)

NONE

2007-07-01

Today's investment decisions in key sectors such as energy, forestry or transport have significant impacts on the levels of greenhouse gas (GHG) emissions over the coming decades. Given the economic and environmental long-term implications of capital investment and retirement, a climate mitigation regime should aim to encourage capital investment in climate-friendly technologies. Many factors affect technology choice and the timing of investment, including investor expectations about future prices and policies. Recent international discussions have focused on the importance of providing more certainty about future climate policy stringency. The design of commitment periods can play a role in creating this environment. This paper assesses how the length of commitment periods influences policy uncertainty and investment decisions. In particular, the paper analyses the relationship between commitment period length and near term investment decisions in climate friendly technology.

Alternative approaches to transmission investment

Welch, J.L. [International Transmission Co., Detroit, MI (United States)

2004-07-01

The International Transmission Company (ITC) is an independent power transmission company that owns, operates and maintains the high voltage transmission system in southeastern Michigan. The company's current focus is on investing in the transmission infrastructure to improve reliability, relieve congestion, improve access to generation and reduce energy costs for consumers. There is a need for investment in power transmission. Trends indicate that power transactions are on the rise while transmission investment is lagging because pricing protocols are inadequate and there is no regional tariff mechanism to allocate the benefits of new investment. The presentation reviewed the applicability of FTRs to transmission owners and the pitfalls of participant funding pricing. It also outlined the regional benefit allocation mechanism (RBAM) with an illustrative example. It was concluded that existing pricing policies must be improved to address the growing need for transmission investment. RBAM is needed to help investors recover costs from project beneficiaries. figs.

There is considerable uncertainty in the Nordic electricity system with respect to the long-term development in production capacity. The process towards liberalisation of the electricity sector started with a situation of a large capacity margin, but this margin is gradually vanishing. Since the potential investors in new production capacity are unaccustomed with investments under the new regime, it is unknown if and when investments will take place. The purpose of the present study is to analyze if and when investors choose to invest in new electricity production capacity depending on their existing portfolio of power producing units. Electricity price scenarios generated with a partial equilibrium model (Balmorel) are combined with a model of investment decisions. In this, various scenarios concerning the development in the Nordic power market, such as new transmission lines between neighbouring countries, more installed wind power, and changes in CO 2 emission trading costs, are used to investigate the consequences for investments in a natural gas fired, combined cycle power plant. The main result of the analysis is that new investments are highly sensitive to investors existing power production portfolio, as new production units affect the merit order in the power market, i.e. compete with the existing power plants.

Hospital Capital Investment During the Great Recession.

Choi, Sung

2017-01-01

Hospital capital investment is important for acquiring and maintaining technology and equipment needed to provide health care. Reduction in capital investment by a hospital has negative implications for patient outcomes. Most hospitals rely on debt and internal cash flow to fund capital investment. The great recession may have made it difficult for hospitals to borrow, thus reducing their capital investment. I investigated the impact of the great recession on capital investment made by California hospitals. Modeling how hospital capital investment may have been liquidity constrained during the recession is a novel contribution to the literature. I estimated the model with California Office of Statewide Health Planning and Development data and system generalized method of moments. Findings suggest that not-for-profit and public hospitals were liquidity constrained during the recession. Comparing the changes in hospital capital investment between 2006 and 2009 showed that hospitals used cash flow to increase capital investment by $2.45 million, other things equal.

Four topic areas are considered: (1) The global context for energy investments, (2) Strategic investments in the gas chain, (3) Conventional and changing approaches to investing in gas and power, (4) New areas of opportunity. The presentation considers the challenging global context for investments and the current oil price outlook and more specifically the backdrop to the growth in demand for gas and its increasing availability and the implications of factors such as energy market liberalization. It notes the regional nature of gas and power markets and considers the issue of stranded supply and demand. It identifies an increasing trend towards investments up and down the gas chain by both traditional and new players and explores BP Amoco's own corporate response. The presentation then briefly reviews four major gas investments which BP Amoco has either already taken or is considering. It then discusses investments in gas to power and the growing environmental agenda, which is bringing a range of new and non-traditional investment opportunities

2006-01-01

This article analyzes R & D investment decisions in an asymmetrical case. The investment decisions share three important characteristics. First, the investment is completely irreversible. Second,there are two kinds of uncertainties over the future returns from the investment and over technology in R & D process, respectively. Third, there is strategic competition in the asymmetrical case. This article presents the optimal investment threshold values and the optimal investment rule of high-efficient firm (leader), and shows that the investment threshold values are reduced by competition of two firms.Finally, the mixed investment strategies for two firms, the probability that each firm separately exercises the option to invest, and the probability that two firms simultaneously exercise the option are given in the paper.

Geopolitics and the corporate investment decision

International Nuclear Information System (INIS)

Boulos, A.J.

1996-01-01

The impact of geopolitics in any international oil company's investment decisions, was discussed. Geopolitics in this context was defined as all government policies, be they economic, political strategic or military, that determine national interests, which a company has to take into account in making an investment decision. Geopolitical considerations have taken on added importance with the arrival of the Cold War and its aftermath, to the point where investment decisions based on traditional parameters such as geological productivity, rates of return, net present values, fiscal and contractual provisions frequently take a back seat to investment decisions that were taken with geopolitical impacts foremost in mind. From time to time, geopolitical factors can even pre-empt corporate investment decisions. The nature of geopolitics, its historical antecedents, the emergence of international rivalries following World War I, intensified after World War II, particularly after the formation of OPEC in 1973, the changing forms of resource ownership, and the general impact of geopolitical factors on corporate investment decisions were reviewed

Full Text Available Entre las fuentes de energías alternativas renovables, la más empleada es la eólica debido a que es competitiva desde el punto de vista de los costos y en general sus permisos para la construcción se obtienen más fácilmente. Sin embargo, a pesar de sus ventajas, el aprovechamiento del viento presenta también desventajas siendo las más serias desde el punto de vista de la ingeniería el rendimiento energético de los generadores y el impacto eléctrico perturbador que los parques eólicos provocan sobre el sistema de potencia, particularmente sobre la calidad del producto. La mejora en una de las limitaciones puede afectar negativamente a la otra, por lo que la solución debe hallarse de ambas problemáticas en forma conjunta. Dado este inconveniente planteado, se considera de importancia fundamental el estudio analítico de los esquemas de funcionamiento de los generadores eólicos, a fin de concluir cuales son los que producen la mayor transferencia de energía, mejorando el aprovechamiento del viento y considerando su impacto desde el punto de vista eléctrico.

Optimal investment horizons

Science.gov (United States)

Simonsen, I.; Jensen, M. H.; Johansen, A.

2002-06-01

In stochastic finance, one traditionally considers the return as a competitive measure of an asset, i.e., the profit generated by that asset after some fixed time span Δt, say one week or one year. This measures how well (or how bad) the asset performs over that given period of time. It has been established that the distribution of returns exhibits ``fat tails'' indicating that large returns occur more frequently than what is expected from standard Gaussian stochastic processes [1-3]. Instead of estimating this ``fat tail'' distribution of returns, we propose here an alternative approach, which is outlined by addressing the following question: What is the smallest time interval needed for an asset to cross a fixed return level of say 10%? For a particular asset, we refer to this time as the investment horizon and the corresponding distribution as the investment horizon distribution. This latter distribution complements that of returns and provides new and possibly crucial information for portfolio design and risk-management, as well as for pricing of more exotic options. By considering historical financial data, exemplified by the Dow Jones Industrial Average, we obtain a novel set of probability distributions for the investment horizons which can be used to estimate the optimal investment horizon for a stock or a future contract.

In the study we justify the theoretical principles and reveal the essence of the relationship concepts: investment climate, investment attractiveness and investment activity. It is proved that the investment attractiveness should be considered as a sign of factorial and important component of the investment climate in the region, and investment activity as a sign score. In the study we can see a wide range of factors shaping favorable conditions for investment activities. The author focuses on the importance of non-traditional factors shaping the investment attractiveness of such as reducing the time to connect to power grid, information communication, improvement of tax reporting procedures, clarity of customs work, the introduction of regulations for obtaining permits for construction of facilities and reducing the number of required documents. This article analyzes of the indices and the key factors of investment attractiveness of the Voronezh region, which attract investment, exceeding the national average. The main ones are the development of new industrial parks with good transport, engineering, business infrastructure. Investors in the region have favorable conditions to carry on business on the prepared sites with painted communications, junctions, allowing them to reduce production costs, while correspondingly increasing the investment attractiveness of the area. Success of the attracting investment in the Voronezh region is largely due to the introduction standard of the executive bodies of state power, including 15 documents designed to make the

Investment Attractiveness of Food Industries in Ukraine

Directory of Open Access Journals (Sweden)

L. О.

2017-02-01

Full Text Available Effective investment is a factor for long-term company development. As enhancement of investment attractiveness is a required condition for economic growth and improvement of living standards, it needs to be on the agenda at government and company level. The article’s objective is to study investment attractiveness of food industries in Ukraine over 2012–2015. Investment attractiveness of food industries can be measured by indicators of liquidity, financial sustainability, and profit rate. Basically, food industries in Ukraine are attractive for investment, which is demonstrated by assessment of the financial indicators. The investment attractiveness worsened slightly in 2015 compared with 2014. The essential problems faced by food industries are shortage of internal funds and negative profit rate of all the activities, assets and own capital. Official statistical data and software package SPSS are used to build the dendrogram, allowing for dividing food industries by level of investment attractiveness into three groups: industries with high, medium and low level of investment attractiveness. It is found that meat industry is the one with the highest level of investment attractiveness. Also, investors should look positively at food-canning industry, oil and animal fat industry, flour-milling industry, starch and starch products industry, and other foods industry.

A total of 3,019 MW in new offshore wind capacity came online in European waters in 2015, more than double the capacity connected to the grid in 2014. Europe’s total offshore wind capacity now stands at 11,027 MW. A further 3,034 MW of capacity, spread across ten projects, reached final investment decision last year, a twofold increase on 2014. These are some of the main figures contained in “The European offshore wind industry - key trends and statistics 2015”, a report published by EWEA. (Author)

Robust control decentralized by sliding ways of electrical of power multi-machines systems; Control robusto descentralizado por modos deslizantes de sistemas electricos de potencia multimaquinas

Huerta Avila, Hector

2008-09-15

This work deals with the problem of robust decentralized control of multimachine electric power systems. These systems are subject to different perturbations, such as short circuits, connection and/or disconnection of loads, lines generators, mechanical torque variations, etc. Then, it is necessary controllers which guarantee robustness under those perturbations to provide electrical energy to the loads with admissible stability margins. Moreover, the controller must be robust under parametric variations due to model uncertainties, and other physical reasons. The electrical power systems are modeled as complex great scale nonlinear systems. Then, the controller design is a challenging problem. Thus, the decentralized control schemes enable to avoid these problems. This work proposes three novel robust nonlinear techniques. The first one is based on the block control and integral sliding modes. The second obtains a sliding manifold from the Hamiltonian model of a nonlinear system to use this manifold in the integral sliding modes. The third technique enables to apply the sliding mode technique to a nonlinear block controllable system, by using Lyapunov function in each block. Then, four control schemes for electric power systems are designed. The four control schemes are robust under the perturbations of electric power systems mentioned above. The controllers proposed can be implemented in any electric power system with n generators, m lines and k loads. [Spanish] Este trabajo esta dedicado al diseno de esquemas de control robustos descentralizados que sean capaces de responder satisfactoriamente en sistemas electricos de potencia multimaquinas. Estos sistemas estan sujetos a perturbaciones de diferentes tipos, como cortos circuitos, entrada y salida de lineas de cargas o de generadores. Es evidente la necesidad de controladores que puedan rechazar estas perturbaciones para proveer energia de calidad y sin interrupciones a todos los usuarios conectados a la red

Investment under Uncertainty and Financial Crisis

The objective of the paper is to test the stability hypothesis – that foreign investors are relatively insulated from uncertainty and how it spills over on their investment adjustment cost. The Q model (implying that investments are explained by the fundamental value of the firm) is implemented...... with reasonable success for firm level panels in Turkey. Robustness of the results and despite the general obstacle that inflation poses on the study is increased by applying different datasets with different time horizons, different measures of investment and profitability and different problems of attrition...... it is found that the decline in the growth of the investment rate for domestic firms is at least twice as high compared to the decline in the growth of the investment rate among foreign held firms....

Economic growth is always accompanied by economic fluctuation. The target of macroeconomic control is to keep a basic balance of economic growth, accelerate the optimization of economic structures and to lead a rapid, sustainable and healthy development of national economies, in order to propel society forward. In order to realize the above goal, investment control must be regarded as the most important policy for economic stability. Readjustment and control of investment includes not only control of aggregate investment, but also structural control which depends on economic-technology relationships between various industries of a national economy. On the basis of the theory of a generalized system, an optimal investment control model for government has been developed. In order to provide a scientific basis for government to formulate a macroeconomic control policy, the model investigates the balance of total supply and aggregate demand through an adjustment in investment decisions realizes a sustainable and stable growth of the national economy. The optimal investment decision function proposed by this study has a unique and specific expression, high regulating precision and computable characteristics.

Power generation investment in electricity markets

International Nuclear Information System (INIS)

2003-01-01

Most IEA countries are liberalizing their electricity markets, shifting the responsibility for financing new investment in power generation to private investors. No longer able to automatically pass on costs to consumers, and with future prices of electricity uncertain, investors face a much riskier environment for investment in electricity infrastructure. This report looks at how investors have responded to the need to internalize investment risk in power generation. While capital and total costs remain the parameters shaping investment choices, the value of technologies which can be installed quickly and operated flexibly is increasingly appreciated. Investors are also managing risk by greater use of contracting, by acquiring retail businesses, and through mergers with natural gas suppliers. While liberalization was supposed to limit government intervention in the electricity market, volatile electricity prices have put pressure on governments to intervene and limit such prices. This study looks at several cases of volatile prices in IEA countries' electricity markets, and finds that while market prices can be a sufficient incentive for new investment in peak capacity, government intervention into the market to limit prices may undermine such investment

We provide an explicit solution using a robust method for an ambiguity averse firm taking this into account. Ambiguity aversion regarding a common risk factor impacts differently than...... ambiguity aversion regarding investment cost residual risk. Correlation between project value and investment cost matters; ambiguity aversion regarding common risk can decrease the investment probability only if correlation is positive.

US Investment Treaties and Labor Standards

Full Text Available Korea and the United States declared the start of negotiations for the establishment of a free trade agreement. The FTA will include investment chapter. That means the Korea-US BIT (Bilateral Investment Treaty talk, which has been deadlocked since 1998, resumes as a part of FTA negotiations. The FTA investment chapter will be based on the US model BIT, which has been updated in 2004. The updated BIT version includes labor clause which provides that parties should not weaken labor standards in an effort to attract foreign investment. This clause is grounded on the criticism raised by labor groups which asserts that competition among countries to attract foreign investment leads to bidding wars in labor standards. No solid evidence is found in support of the hypothesis that foreign investors favor countries with lower labor standards. Nonetheless, some countries have offered special incentives to investors that limit labor rights in the belief that doing so would help attract foreign investment, especially in export processing or special economic zones. In this regard, the Korea's Act on free economic zones which provides exceptional labor standards to foreign invested enterprise in those zones may become an issue in reaching the FTA. This article contemplates the "not lowering labor standards" provision in the US BIT model and its implications on the FTA talks with the US.

In cooperation with the Triodos Bank, SEV carried out a study on the possibility to invest money from green investment funds at low interest in houses which are designed and built in a sustainable and energy efficient way. By order of the Triodos Bank and SEV others drafted a guideline to assess dwellings and calculated the financial and economical consequences of green investments in sustainable housing. The results of those studies formed the basis of the SEV recommendation to the Dutch State Secretary of Housing and Planning and the Dutch State Secretary of Economic Affairs, April 1996, to expand the planned Green Investment Regulation to the possibility to invest money in sustainable houses. It is expected that the Green Investment Regulation will come into effect September 1996. 2 appendices

Financial Development and Investment-Cash Flow Sensitivity

Directory of Open Access Journals (Sweden)

Jungwon Suh

2007-06-01

Full Text Available Using firm-level data from thirty-five countries around the world, this paper empirically examines whether investment-cash flow sensitivity reflects financial constraints. Recent US studies have raised questions on the prediction that investment-cash flow sensitivity is a measure of financial constraints. Looking at thirty-five countries with varying degrees of financial development, this study tests whether investment-cash flow sensitivity is in fact related to financial constraints. In most countries, the evidence supporting the argument that firms likely facing financially constraints display high investment-cash flow sensitivity is weak. Moreover, the evidence that firms in the absence of developed financial markets display high investment-cash flow sensitivity is also weak. Overall, the results from this international investigation do not support the prediction that investment-cash flow sensitivity reflects financial constraints.

Financial Investing Made for Women: The Economic and Psychological Reasons Why Women Invest Differently Than Men

Directory of Open Access Journals (Sweden)

Carolina M. Reece

2013-07-01

Full Text Available Financial Investing is becoming not only a way to plan for a future source of retirement, but also a method to control a personal financial situation without having to rely on government aid or family member support to survive during the elderly years. Today, individuals cannot depend on social security being available in the future for financial support. It is especially vital for women to become more interested in making long-term investments that will provide a secure and effective approach to money management and financial planning. However, as various studies have concluded, women are less interested than men in managing their finances due to various economic and psychological reasons related to risk aversion, sociopolitical and biological factors, and income. This study reviews previous research findings related to the relationship between women and investments, as well as several economic and psychological reasons behind the gender gap on financial investing are presented. Surveys were used to identify the main reasons for women’s tendency to rely less on financial investments. It was found that women who had some source of financial investment showed confidence in the stock market, as well as in their financial decisions. These results contradict some of the findings shown in previous research.

The economic content of the term “investment attractiveness”

2016-01-01

Full Text Available The article is devoted to the definition of the economic content of the concept of “investment attraction” and the study of the criteria of investment attractiveness. We conducted a retrospective analysis and systematization of the various definitions of “capital”, “investment”, “investment attraction”, given by domestic and foreign authors. A generalized definition of capital is given: “capital’ is an objective economic category, which offers a business entity to carry out its investment activities in order to expand the scope and value of the business, making a profit and improve its investment attractiveness. It is emphasized that the concept of “investment” is broader than the concept of “capital”: it is investment in capital with varying degrees of liquidity for the purpose of subsequent increments and increase the value of the business entity. The author defines the main characteristics of the investment. A distinction of the term “investment attractiveness” of similar concepts, “market attractiveness”, “investment climate”, “investment image”, “investment potential” is made. It is concluded that the investment attractiveness is a component of the investment climate, which is characterized by an objective character and eliminates the subjectivity. Based on the understanding of different approaches to the study of the investment attractiveness and define its criteria the author offers a brief description of the concept of “investment attractiveness”: investment attractiveness is an independent economic category – a set of internal and external factors, as well as qualitative and quantitative indicators of the investment potential of any of the levels of the economic system – state, regional, sectoral, level of economic entities. Evaluation of investment attractiveness at all levels of the economic system is carried out in the current period (current situation analysis and forecast

This report studies the development of criteria for assessing the compatibility of financial investments with the international goal to limit global temperature increase to below 2 C above pre-industrial levels. The findings are intended as a starting point and a key input for a longer term process to develop consensus-based 2 C investing criteria. The focus here is placed on investments in projects and physical assets, in particular of development and climate finance organisations. In order to limit global temperature increase to 2 C, global greenhouse gas (GHG) emissions will have to be reduced significantly, eventually to zero, during the course of this century. This requires shifting capital from high to low carbon investments as well as significant capital mobilisation for investments in 2 C-compatible infrastructure. Given the long lifetime of physical assets, and the urgency of decarbonisation over the coming decades, this needs to begin today. Public financial institutions can play a prominent role in contributing to aligning investment flows with the 2 C limit, as well as in closing the current infrastructure investment gap, responding to their explicit or implicit climate mandates and leadership role in the finance sector. The majority of international financial institutions integrate climate considerations into their finance decisions to some degree, and are familiar with different types of criteria, including positive and negative lists, qualitative and quantitative benchmarks, and the use of shadow carbon pricing. However, current approaches do not link to the 2 C limit. 2 C investment criteria are therefore needed to guide investors in this regard. Such criteria may also support other purposes, including an understanding of climate risks and improved reporting and accountability.

Full Text Available Modernization of the Russian economy and creation of conditions for its economic growth demand activization of investment activity that is possible by means of its financial stimulation. Financial stimulation of investment activity defines the need of changes of the contents, the directions and ways of implementation of the financial relations between subjects of investment activity. Financial stimulation of investment activity is carried out via the mechanism in the context of which these financial relations are settled. For defining the mechanism of financial stimulation of investment activity the authors consider the very concept of financial mechanism. The conclusion is drawn that all elements of the financial mechanism are the integrated unity, they are interdependent and interconnected, and the combination of types, forms, methods of the organization of the financial relations forms “a design of the financial mechanism”. The article specifies the maintenance of the mechanism of financial stimulation of investment activity, and reveals its essence. The structure of the mechanism of financial stimulation of investment activity is presented by the following elements: subjects of financial stimulation of investment activity, the purpose of attraction of investments by them, set of financial methods and tools, sources of means of achievement of goals, standard - legal and information support of financial stimulation of investment activity. It is proved that in the mechanism of financial stimulation of investment activity the leading role is played by the state by means of forms of direct and indirect participation in attraction of investments, each of which is realized by means of specific methods and the corresponding tools. The widespread instrument of financial stimulation of investment activity is the investments which are carried out by the state institutes of development participating in the organization of the process of financial

It is essential for the sustainable operations and the economy of the farm that such investments are successful. In this research, different stages of the investment process of farms were studied as well as the use of information and the success perceived during the investment process. The study was carried out with mail surveys and telephone interviews on the Finnish Farm Accountancy Data Network (FADN farms. The most challenging investments were in animal husbandry buildings and, as to these investments, the comparison of alternatives was the most challenging stage. For most investments, the planning phase was considered more challenging than the implementation. Before making the decision, farmers acquired information from many sources, of which the opinion of the main customer and the experiences of fellow farmers were the most valued. Some of the products considered were so new on the market that it was not easy to get adequate information and, furthermore, the information given by suppliers was not always accurate. Decision-making was supported by calculations, but qualitative factors had a dominating role. Large basic decisions were made relatively quickly, while details needed a longer time to process. In general, farm managers were satisfied with their investments. Improvements in work quality and quantity were especially mentioned and generally qualitative factors were the ones first in mind when evaluating the successfulness of the investment.;

Calculating investment potential in South America

International Nuclear Information System (INIS)

Smith, J.L.

1995-01-01

Taxes and licensing provisions typically increase overall costs for private investors, and therefore impede private investment. In addition, the design and structure of tax systems in each country affect the extent to which financial risks are borne by private investors, rather than by the host government. Tax systems that increase perceived financial risks stemming from unpredictable oil prices, development costs and physical characteristics of undiscovered or undeveloped oil fields raise further impediments to private investment. This analysis focuses on both aspects of the investment climate--risk and return--and the way that investment incentives within three South American countries are influenced by tax and licensing regimes

Micro-energy markets: The role of a consumer preference pricing strategy on microgrid energy investment

2014-01-01

The fragility of the modern electrical grid is exposed during random events such as storms, sporting events and often simply routine operation. Even with these obvious flaws large utilities and governments have been slow to create robust solutions due to the need of large capital investments required to address the issues. In this light creative economic and engineering solutions are desired to finance the needed upgrades. Driven by the requirement to have uninterrupted power that meets customers desires this research focuses on linking consumer preferences to a type of energy source in order to best fulfill stakeholder priorities. This approach is in contrast to the current and prevalent lowest cost methods to producing and consuming energy. This research yields a preliminary ‘micro-energy market’ that consists of an energy network architecture, pricing methodology and mathematical template which quantifies potential economic inefficiencies. If exploited these inefficiencies could be used to fund investment into various energy sources that provide unmet needs such as reduced carbon footprint, renewable, quality, and local production. These inefficiencies can be best exploited within the structure of a microgrid. Identification of opportunities on this smaller scale can provide an incentive for producers to develop a robust set of production facilities of varying size and characteristics to meet the consumer preferences. A stochastic optimization model of a microgrid implementation for a small military installation is used to evaluate the effects of this pricing methodology. The energy production of the resulting microgrid would be optimized to meet consumer preferences and minimize economic inefficiency. - Highlights: • This research focuses on linking consumer preferences to a type of energy source. • Pricing methodology quantifies strategic investments in alternative sources. • Inefficiencies could be used to fund investment into various energy sources

Inconsistent Investment and Consumption Problems

Kronborg, Morten Tolver; Steffensen, Mogens

2015-01-01

In a traditional Black–Scholes market we develop a verification theorem for a general class of investment and consumption problems where the standard dynamic programming principle does not hold. The theorem is an extension of the standard Hamilton–Jacobi–Bellman equation in the form of a system...... of non-linear differential equations. We derive the optimal investment and consumption strategy for a mean-variance investor without pre-commitment endowed with labor income. In the case of constant risk aversion it turns out that the optimal amount of money to invest in stocks is independent of wealth...... of future labor income net of consumption. Using the verification theorem we give a detailed analysis of this problem. It turns out that the optimal amount of money to invest in stocks is given by a linear function of wealth plus the financial value of future labor income net of consumption. The optimal...

Tehrani, B.S.; Bocquer, J.C.; Tomoda, T.

2014-01-01

While nuclear power may experience a technological breakthrough in Europe with Generation IV nuclear reactors within 2040, several events could question this possibility such as the Fukushima accident, the climate issues and the electricity market liberalization. This paper aims at analyzing investment choices in power generation capacities in the European scope, using simple DSM-inspired approaches. The power company and interacting stake holders in the investment choice process are considered as a complex system, and dependencies between investment drivers associated with each stake holder are studied. Focusing on the value for the power company, the compatibility of each power company with each of considered technologies is assessed through a Domain Mapping Matrix, including not only technical drivers, but also associated policy and market drivers. Technology preferences are modeled for main European companies in a set of scenarios, these preferences being then used to explore trends in generation mix. (authors)

FOREIGN DIRECT INVESTMENTS DURING FINANCIAL CRISES

Directory of Open Access Journals (Sweden)

VINTILA DENISIA MARIANA

2011-12-01

Full Text Available The fundamental idea of International capital flows is that short-term flows can be easily reversed, while flows on a longer time horizon are more stable. Crises are associated with withdrawals of short-term capital flows and growth of the foreign direct investment flows. The current crisis has meant a major decline of international capital flows, also of the foreign direct investment. The analysis in this article tries to establish if and under which conditions foreign direct investments can bring greater stability during the crisis, comparing the evolution of foreign direct investments in the current crisis with their response in previous crises. We show that during previous crises foreign direct investments were stable, behaving differently from other types of capital. Yet, during the current crisis, foreign direct investments have proven to be not so stable and all the components declined, raising questions about the resumption of the positive trend. The stability of foreign direct investments in the past was given by the increase of mergers and acquisitions during the crisis, reflecting fire-sale FDI. This feature is not found in the current crisis as mergers and acquisitions were severe affected by the crises and recorded a major decline.

By probing the processes of exclusion of transsexuals from the political sphere, this article offers contributions to social and political theory through an examination of the processes of exclusion from the category "human." This article considers how the erasure of investment in their own embodied sex constructs a platform from which to blame others for sex/gender variance, as well as to justify that blaming. Bringing together Giorgio Agamben, Georges Bataille, Judith Butler, and Nikolas Rose with transphobia, medicalization in psychiatry, law, and ethopolitics, this article questions whose investment in sexed embodiment counts and why that investment might be seen as "crazy."

Dancing with the Dragon: Canadian Investment in China and Chinese Investment in Canada

Directory of Open Access Journals (Sweden)

Josephine Smart

2012-09-01

Full Text Available While Canadian trade and investment with China is today relatively modest, with China well on track to displace the United States as the world’s largest economy, Canada must make it a priority to prepare for a future characterized by dramatically increased trade and investment between our two countries. This paper sheds light on some the issues and measures Canadian governments will have to consider as they look to establish safe and prosperous relationships with China. To begin with, Canadians choosing to invest in China must be prepared for the risk inherent in that country’s peculiar “capitalism with socialist characteristics.” The Chinese state continues to play an interventionist role in many significant sectors in the economy, and the strategy behind China’s overseas investment in countries such as Canada is specifically aimed at furthering China’s own national security goals and geopolitical influence. Canadians wishing to do business in China will also require great cultural competency. The cultural institution known as guanxi — in which gifts to sway influence are considered an acceptable, even desirable practice — persists in China, with even native Chinese unclear on where to draw the line between “good” guanxi and “bad” corruption. At home, Canadians may soon be forced to confront questions about how much of our own land security and natural resource security we are willing to compromise by permitting Chinese investment to gather up our farmland and key industries. Canadians should decide sooner, not later, how well our own strategic interests are served by permitting unrestricted Chinese investment in our economy. In anticipation of these issues, Canada’s federal and provincial governments should provide increased support for a more comprehensive training and research infrastructure that better prepares Canadians for the growing bilateral trade between our countries. They should also reinvest in the

Security Investment in Contagious Networks.

Hasheminasab, Seyed Alireza; Tork Ladani, Behrouz

2018-01-16

Security of the systems is normally interdependent in such a way that security risks of one part affect other parts and threats spread through the vulnerable links in the network. So, the risks of the systems can be mitigated through investments in the security of interconnecting links. This article takes an innovative look at the problem of security investment of nodes on their vulnerable links in a given contagious network as a game-theoretic model that can be applied to a variety of applications including information systems. In the proposed game model, each node computes its corresponding risk based on the value of its assets, vulnerabilities, and threats to determine the optimum level of security investments on its external links respecting its limited budget. Furthermore, direct and indirect nonlinear influences of a node's security investment on the risks of other nodes are considered. The existence and uniqueness of the game's Nash equilibrium in the proposed game are also proved. Further analysis of the model in a practical case revealed that taking advantage of the investment effects of other players, perfectly rational players (i.e., those who use the utility function of the proposed game model) make more cost-effective decisions than selfish nonrational or semirational players. © 2018 Society for Risk Analysis.

Investing in European market real property through reits

Science.gov (United States)

Adamuscin, A.

2010-03-01

For institutional and private investors, investing in real estate represents an attractive form of the consignment of their money. Real estate provides a regular source of income in the form of the rent from or interest on the credit provided. At the same time, real estate is a good investment instrument, because it provides diversified contributions and security against inflation for investors. In their efforts to diversify risk, investors are expressing growing interest in investing in the whole European Union. The success of Real Estate Investment Trusts (REITs) in the U.S. also opened the door for investing in this market for small investors, which is the reason for the development of this type of investment company in the European arena. One problem concerning the development of European real estate investment funds is the unsolved issue of the harmonization of the legislation and regulatory safety measures, which would enable the creation of a common market for new investment products in Europe.

Work environment investments are important in order to create a healthy and safe workplace. This article presents findings from a seven-step interventions process aimed at examining and following-up work environment investments in small and medium-sized enterprises (SMEs), with a particular focus on air contaminants. Three different cases were analyzed and included in the study: (a) an educational center for welding; (b) a paint station in furniture manufacturing; (c) a joinery in furniture manufacturing. The results show that the work environment investments were highly appreciated by the employees and managers, but at the same time the investment could be optimized through markedly decreased exposure levels for the worker. Factors such as follow-ups of the investment, education and training in how to use the equipment, worker involvement in the process and leadership engagement are important in order to optimize work environment investments.

Investment risks under uncertain climate change policy

2007-01-01

This paper describes results from a model of decision-making under uncertainty using a real options methodology, developed by the International Energy Agency (IEA). The model represents investment decisions in power generation from the perspective of a private company. The investments are subject to uncertain future climate policy, which is treated as an external risk factor over which the company has no control. The aims of this paper are to (i) quantify these regulatory risks in order to improve understanding of how policy uncertainty may affect investment behaviour by private companies and (ii) illustrate the effectiveness of the real options approach as a policy analysis tool. The study analysed firms' investment options of coal- and gas-fired power plants and carbon capture and storage (CCS) technologies. Policy uncertainty is represented as an exogenous event that creates uncertainty in the carbon price. Our findings indicate that climate policy uncertainty creates a risk premium for power generation investments. In the case of gas- and coal-fired power generation, the risk premium would lead to an increase in electricity prices of 5-10% in order to stimulate investment. In the case of CCS, the risk premium would increase the carbon price required to stimulate investment by 16-37% compared to a situation of perfect certainty. The option to retrofit CCS acts as a hedge against high future carbon prices, and could accelerate investment in coal plant. This paper concludes that to minimise investment risks in low carbon technologies, policy-makers should aim to provide some long-term regulatory certainty. (author)

Full Text Available The article deals with investment and business opportunities offered by silver. Silver is the metal used in industry and for investing at financial markets. The main problem related to this real commodity is the issue of “the undervaluation” of its investment options, if compared to gold. If considering silver as the investment option, its investment potential is significantly enhanced by its industrial usage. The aim of this paper is to highlight business and investment opportunities for both professionals and non professional investors at the commodity markets. The price growth of this investment and industrial metal can generate profits for the investors. And on the other hand, industries which cannot do without silver in their production may efficiently utilize the knowledge of setting up its price at the markets.

Investment appraisal concerned with investments in fire safety systems is discussed. Particular attention is directed at evaluating, in terms of the Bayesian decision theory, the risk reduction that investment in a fire safety system involves. It is shown how the monetary value of the change from a building design without any specific fire protection system to one including such a system can be estimated by use of quantitative risk analysis, the results of which are expressed in terms of a Risk-adjusted net present value. This represents the intrinsic monetary value of investing in the fire safety system. The method suggested is exemplified by a case study performed in an Avesta Sheffield factory.

Purpose-The purpose of this paper is to analyze and examine the role of accounting conservatism on firm investment behavior in China.Design/methodology/approach-By combining a developed theoretical framework and empirical study,this paper examines the impacts of accounting conservatism on firm investment.The sample and data are all collected from Wind and CAMAR databases.Findings-The paper finds that the association between accounting conservatism and capital expenditure is significantly positive when inside capital is not enough to use for investment,suggesting that conservatism can expend the level of investment by decreasing information asymmetry and cost of capital;however,the association between accounting conservatism and capital expenditure is significantly negative when inside capital is enough to use for investment,suggesting that conservatism can curtail the level of investment by mitigating the interest conflicts between management and outside shareholders and decreasing agency costs.Additionally,the paper finds that the severity of information asymmetry and agency problem affects the role of accounting conservatism on firm investment behaviour,and the association between accounting conservatism and capital expenditure is weaker for firms with ultimate ownership controller as local government or individuals.Originality/value-This is the first paper to analyze and examine the impacts of accounting conservatism on firm investment in China directly.The findings are also useful to explain the awkward predicament found by prior literature.

The tasks of the system of the national economy investment safety are the following: developing investment potential, creating favourable investment climate, forming mechanisms of stable investment activity in the key branches of economy. At the same time, it should also be noted that the complex approach that would allow sufficiently justifying and practically solve the problems of defining indicators, factors of the investment policy and directions of its assurance in realization of the mechanism of investment policy is not sufficiently developed nowadays. This fact determines research topicality. The issue of assuring investment safety is of a special importance in Ukraine that has to assure market economy development, to overcome deformations in the economy structure, to renew products and production apparatus in the industry, to master new kinds of activities. Methodology. The survey is based on the generalization and development of views of the scientific-economic schools, uses approaches of the international agencies and recommendation and normative materials of Ukraine concerning realization of the state investment policy as a totality of interrelated levels and subsystems that allows establishing main functions of the investment safety system. Results of the survey shows that the mechanism of investment safety includes some kinds, forms and methods of organizing investment relations and investment activity, ways of their quantitative determination and establishing interdependence. The concept of investment policy is based on the complex approach and includes the blocks which are locally structured in such way that they allow forming adequate system of its indicators and conducting monitoring of their changes under the influence of the determined factors.

Inflation Protected Investment Strategies

Directory of Open Access Journals (Sweden)

Mirco Mahlstedt

2016-03-01

Full Text Available In this paper, a dynamic inflation-protected investment strategy is presented, which is based on traditional asset classes and Markov-switching models. Different stock market, as well as inflation regimes are identified, and within those regimes, the inflation hedging potential of stocks, bonds, real estate, commodities and gold are investigated. Within each regime, we determine optimal investment portfolios driven by the investment idea of protection from losses due to changing inflation if inflation is rising or high, but decoupling the performance from inflation if inflation is low. The results clearly indicate that these asset classes behave differently in different stock market and inflation regimes. Whereas in the long-run, we agree with the general opinion in the literature that stocks and bonds are a suitable hedge against inflation, we observe for short time horizons that the hedging potential of each asset class, especially of real estate and commodities, depend strongly on the state of the current market environment. Thus, our approach provides a possible explanation for different statements in the literature regarding the inflation hedging properties of these asset classes. A dynamic inflation-protected investment strategy is developed, which combines inflation protection and upside potential. This strategy outperforms standard buy-and-hold strategies, as well as the well-known 1 N -portfolio.

Full Text Available The notion of investment is extremely complex, perceived with different meanings and significations. The use of investment strategies in the management activity implies the application of scientific techniques and methods. In order to ensure a constant economic growth it is necessary to prepare investment projects. In practice the predominant one is the investment activity based on real investments performed for the modernising of assets, in order to ensure their physical and moral wear and tear.

Foreign investment multinational companies and economic development

Directory of Open Access Journals (Sweden)

Popov Đorđe

2013-01-01

Full Text Available There is no universal answer on the question whether foreign investments stimulate economic development. The positive effect of foreign direct investments will follow when the investments is carried out under normal conditions of competition. That means, above all, low barriers for foreign trade and the low level of restrictions for foreign owned companies. In such circumstances, multinational corporations can assist the economies of penetration to make its businesses more efficient. Foreign investors bring with them brand new types of economic activities and in that way shifting the limits of business opportunities in the countries of penetration. But if the investments are implemented in markets protected with protectionist barriers of various kinds, then they could have negative effects. The negative effects are in particularly reflected in the inefficient use of domestic resources. Foreign investments depend on the macro and micro institutional reforms, low inflation, real exchange rate, and reasonably efficient legal system that protects the property rights and encourages savings and investment. The low level of corruption, together with the foregoing conditions is a prerequisite for the creation of a stimulating environment for foreign investments.

A new Global Investment Framework for Women's and Children's Health demonstrates how investment in women's and children's health will secure high health, social, and economic returns. We costed health systems strengthening and six investment packages for: maternal and newborn health, child health, immunisation, family planning, HIV/AIDS, and malaria. Nutrition is a cross-cutting theme. We then used simulation modelling to estimate the health and socioeconomic returns of these investments. Increasing health expenditure by just $5 per person per year up to 2035 in 74 high-burden countries could yield up to nine times that value in economic and social benefits. These returns include greater gross domestic product (GDP) growth through improved productivity, and prevention of the needless deaths of 147 million children, 32 million stillbirths, and 5 million women by 2035. These gains could be achieved by an additional investment of $30 billion per year, equivalent to a 2% increase above current spending. Copyright © 2014 Elsevier Ltd. All rights reserved.

Leverage, monetary policy, and firm investment

OpenAIRE

Charles X. Hu

1999-01-01

In this paper, I investigate whether the effects of monetary policy on firm investment can be transmitted through leverage. I find that monetary contractions reduce the growth of investment more for highly leveraged firms than for less leveraged firms. The results suggest that the board credit channel for monetary policy exists, and that it can operate through leverage, as adverse monetary shocks aggravate real debt burdens and raise the effective costs of investment.

Crisis will impact investments

International Nuclear Information System (INIS)

2008-01-01

This paper summarizes the content of Capgemini's 10. European Energy Markets Observatory (EEMO) report. The EEMO is an annual report that tracks the progress in establishing an open and competitive electricity and gas market in the 27 European countries, including Norway and Switzerland. This tenth edition is based on 2007 and winter 2007-2008 data sets. A 1 trillion euros infrastructure investment is required to build the plants, electrical lines and gas pipelines needed in Europe over the next 25 years. Although today's credit crunch could severely hurt the investment cycle, analysts also anticipate a difficult period for the European energy markets once the recession is over. The report said that Europe has yet to solve the related issues of responding to its energy demand, while curbing its carbon dioxide (CO 2 ) emissions. In 2007, even at a slower pace than previous years, analysts said European electricity consumption still increased by 0.9% and CO 2 emissions stabilized, instead of decreasing. Despite the mild weather, the electricity security of supply deteriorated, analysts said. The Union for the Coordination of Transmission of Electricity (UCTE) real margin - which takes into account non-usable and unavailable generation capacities - dropped from 7.6% in 2006 to 5.3% in 2007. Analysts said without a significant and vigorous investment program in electricity and gas infrastructures, Europe's energy supply security will be threatened. Since the low point in 2005, utilities started to invest again, but have made energy mix choices that are not moving toward a reduction in CO 2 emissions as the majority (58%) of the planned generation capacities will be fossil-fueled. In 2007, investments in renewable capacities grew fast, wind being the industry's preference, with an addition of 8.3 gigawatt (GW) renewables in Europe. However, analysts said this type of 'non-scheduable' source is not always available during peak hours. This partially explains the security

Output-based allocation and investment in clean technologies

Energy Technology Data Exchange (ETDEWEB)

Rosendahl, Knut Einar; Storroesten, Halvor Briseid

2011-07-01

Allocation of emission allowances may affect firms' incentives to invest in clean technologies. In this paper we show that so-called output-based allocation tends to stimulate such investments as long as individual firms do not assume the regulator to tighten the allocation rule as a consequence of their investments. The explanation is that output-based allocation creates an implicit subsidy to the firms' output, which increases production, leads to a higher price of allowances, and thus increases the incentives to invest in clean technologies. On the other hand, if the firms expect the regulator to tighten the allocation rule after observing their clean technology investment, the firms' incentives to invest are moderated. If strong, this last effect may outweigh the enhanced investment incentives induced by increased output and higher allowance price. (Author)

Solution to the problem of optimum power flows with restrictions of safety by a modified particle optimizer; Solucion del problema de flujos de potencia optimo con restricciones de seguridad por un optimizador de particulas modificado

Energy Technology Data Exchange (ETDEWEB)

Onarte Yumbla, Pablo Enrique

2008-02-15

The power system optimal power flow (OPF) objective is to obtain a start-up and shut-down schedule of generating units to meet the required demand at minimum production cost, satisfying units' and system's operating constraints, by adjusting the power system control variables. Nowadays, the transmission system can be considered as an independent transmission company that provides open access to all participants. Any pricing scheme should compensate transmission companies fairly for providing transmission services and allocate entire transmissions costs among all transmission users. This thesis uses a transmission pricing scheme using a power flow tracing method to determine the actual contributions of generators to each link flow. Furthermore, the power system must be capable to withstand the loss of any component (e.g., lines, transformers, generators) without jeopardizing the system's operation, guaranteeing its security; such events are often termed probable or credible contingencies, this problem is known as optimal power flow with security constrains (OPF-SC). Additionally, constraints in generating units' limits, minimum and maximum up- and down-time, slope-down and slope-up, voltage profile improved and coupling constraints between the pre- and the post-contingency states and transient stability constraints have been taken into account. A particle swarm optimizer with reconstruction operators (PSO-RO) for solving the OPF-SC is proposed. To handle the constraints of the problem, such reconstruction operators and an external penalty are adopted. The reconstruction operators allow that all particles representing a possible solution satisfy the units' operating constraints, while looking for the optimal solution only within the feasible space, reducing the computing time and improving the quality of the achieved solution.

Reiter, K L; Smith, D G; Wheeler, J R; Rivenson, H L

2000-01-01

Capital investment decisions are among the most important decisions made by firms. They determine the firm's capacity for providing services and commit the firm's cash for an extended period of time. Interviews with chief financial officers of leading health care systems reveal capital investment strategies that generally follow the recommendations of modern finance theory. Still, there is substantial variation in capital budgeting techniques, methods of risk adjustment, and the importance of qualitative considerations in investment decision making. There is also variation in delegation of investment decision making to operating units and methods of performance evaluation. Health care systems face the same challenges as other organizations in developing and implementing capital investment strategies that use consistent methods for evaluation of projects that have inconsistent aims and outcomes.

LEVERAGE IMPACTS ON AGRO-INDUSTRIAL COMPANY INVESTMENTS

2018-03-01

Full Text Available Agro-industry has an important role in Indonesian economic growth. One of the crucial constraints in agro-industry investments in developing country is due to limited access to investment fund. This research was aimed to analyze the impacts of leverage on the agro-industrial company investments. The research used financial report data of the manufacturing industries on agro-industrial bases registered in Indonesian Stock-Exchange from 2007 to 2016. The data were analyzed using panel data regression analysis. The results of the research showed that the leverage influenced negatively on the agro-industrial companies. Cash flow has a negative impact on the company investments, which shows the existence of financial constraints when the company decide to invest.

Delaying investments in sensor technology: The rationality of dairy farmers' investment decisions illustrated within the framework of real options theory.

Science.gov (United States)

Rutten, C J; Steeneveld, W; Oude Lansink, A G J M; Hogeveen, H

2018-05-02

The adoption rate of sensors on dairy farms varies widely. Whereas some sensors are hardly adopted, others are adopted by many farmers. A potential rational explanation for the difference in adoption may be the expected future technological progress in the sensor technology and expected future improved decision support possibilities. For some sensors not much progress can be expected because the technology has already made enormous progress in recent years, whereas for sensors that have only recently been introduced on the market, much progress can be expected. The adoption of sensors may thus be partly explained by uncertainty about the investment decision, in which uncertainty lays in the future performance of the sensors and uncertainty about whether improved informed decision support will become available. The overall aim was to offer a plausible example of why a sensor may not be adopted now. To explain this, the role of uncertainty about technological progress in the investment decision was illustrated for highly adopted sensors (automated estrus detection) and hardly adopted sensors (automated body condition score). This theoretical illustration uses the real options theory, which accounts for the role of uncertainty in the timing of investment decisions. A discrete event model, simulating a farm of 100 dairy cows, was developed to estimate the net present value (NPV) of investing now and investing in 5 yr in both sensor systems. The results show that investing now in automated estrus detection resulted in a higher NPV than investing 5 yr from now, whereas for the automated body condition score postponing the investment resulted in a higher NPV compared with investing now. These results are in line with the observation that farmers postpone investments in sensors. Also, the current high adoption of automated estrus detection sensors can be explained because the NPV of investing now is higher than the NPV of investing in 5 yr. The results confirm that

ZHANG Ai-hua; ZHAO Lian-qiang; SHU Hua-ying

2007-01-01

This essay analyzes the data of Chinese telecommunication market, telecommunication investments and investment benefits over the past 20 years. On the basis of these data, the essay reviews Chinese changing telecommunication policies and discusses the major events in the course of China's telecommunication development. It is argued that telecommunication policies, regime backgrounds and market demand characteristics have a significant impact on investment decision mode in telecommunication industry. The evolution of network investments decision mode in China's telecommunication has corresponded to the transformation of these key factors. Considering the special events in the development of Chinese telecommunication as divisions, the essay discusses three stages of the evolution of investments decision mode in China's telecommunication. With the firm environment and problems that Chinese telecommunication operators have been facing since 2000 analyzed. it is demonstrated that Chinese telecommunication operators should change their mode of investment decision into the "profit-oriented investment decision mode" in order to achieve a high growth performance in the capital market,. This investment decision mode will result in increase of the investment profit with limited investment capital. The main procedure of profit-oriented investment decision mode is set out, which is abstracted to a mathematical model eventually.

Three Target Sectors for a European Investment Strategy

Janin, Lionel; Douillard, Pierre

2014-11-01

While the president of the European Commission is getting ready to present the 'Juncker package' announced in July 2014, to revive activity in Europe through investment, what are the sectors in which these investments may be concentrated? The overall analysis of investment gaps in the euro zone has confirmed the requirement for a European macro-economic revival effort that involves investment, public or private, undertaken very quickly, even though this diagnosis varies depending on the country. The drivers of a European investment strategy are fiscal, regulatory and financial and are based on the selection of projects for the future. This third 'Note d'analyse' addresses the topic of investment potential in three key sectors: transport, energy and the digital sector, for which the amount of additional investment could reach euro 120 billion per year and thus, over three years, be higher than the forecasts in the Juncker plan. This maximalist amount mainly corresponds to the implementation of an ambitious energy-climate policy. Given current budgetary constraints, carefully selecting the desired investments, for which their social utility must be validated, is imperative: socioeconomic evaluation is the appropriate approach, particularly for taking into account the environmental externalities that now justify significant investments in the ecological transition.

Summary of the World Energy Investment Outlook 2003

International Nuclear Information System (INIS)

2004-01-01

The current edition of the World Energy Investment Outlook published by the International Energy Agency (IEA) focuses on the foreseeable worldwide investment requirement in the energy sector. The study lists these conclusions, among others: -Total investments of U.S. dollar 16,000 billion worldwide are needed for the energy supply infrastructure over the period 2001 to 2030. They are necessary to add to the power supply capacities and to replace existing power systems and power supply systems. - The financial resources available worldwide are sufficient, basically, to finance the energy investments forecast in the study. The framework conditions necessary for this purpose must be established. - The world energy resources are sufficient to meet the projected demand. Mobilizing the investments depends on the ability of the energy sector to hold its own in the competition for capital with other sectors of the economy. - Energy investments will be dominated by the electricity sector. This sector is likely to absorb nearly U.S. dollar 10,000 billion, or 60% of the total investment. - The developing countries, where energy generation and consumption are going to increase at the fastest rate, will take nearly half of the energy investment worldwide. - A major share of these energy investments is needed to keep up the present level of supply. - The largest share of investments into fossil sources of energy will be spent on extraction costs, exploration included, with different shares applying to the different sources of energy.

Developing country governments and aid agencies face difficult decisions on how best to allocate their finite resources. Investments in many different sectors -including education, water and sanitation, transportation, and health- can all reap social and economic benefits. This report focuses specifically on the health sector. It presents compelling evidence of the value of scaling-up health investments. The economic case for increasing these investments in health has never been stronger. Having made progress in reducing maternal and child mortality, and deaths from infectious diseases, it is essential that policymakers do not become complacent. These gains will be quickly reversed without sustained health investments. Scaled-up investments will be needed to tackle the emerging non-communicable disease (NCD) burden and to achieve universal health coverage (UHC). The value of investment in health far beyond its performance is reflected in economic prosperity through gross domestic product (GDP). People put a high monetary value on the additional years of life that health investments can bring -an inherent value to being alive for longer, unrelated to productivity. Policymakers need to do more to ensure that spending on health reflects people's priorities. To make sure services are accessible to all, governments have a clear role to play in financing health. Without public financing, there will be some who cannot afford the care they need, and they will be forced to choose sickness -perhaps even death- and financial ruin; a devastating choice that already pushes 150 million people into poverty every year. In low-income countries (LICs) and middle-income countries (MICs), public financing should be used to achieve universal coverage with a package of highly cost-effective interventions ('best buys'). Governments failing to protect the health and wealth of their people in this way will be unable to reap the benefits of long-term economic prosperity and growth. Public

Direct Spanish Investments in Latin America

Directory of Open Access Journals (Sweden)

Alfredo Arahuetes García

1995-11-01

Full Text Available In the period 1981-1992, the international flow of direct investments witnessed significant changes which affected their magnitude, geographical orientation, sectorial distribution, forms of investment and sources of financing. This happened in such a way that traditional distribution among industrialized and developing countries was modified as was the capacity for attraction of the different areas in development. In this sense, the main contrast could be seen in the growing importance of East and South East Asia and the decline of Latin American countries which traditionally have been the largest receivers of direct investments within the group of developing countries. The expansive phase of direct investments begun in 1986 threatened to exclude Latin American countries but the establishment of a new framework for the treatment of the problem of external debt -the Brady Plan-, the change in the context of theinternational economy in 1990 and the stability and economic growth of the countries of the region favoured, without a doubt, the recovery of the capacity for attraction for new flows of direct investments regarding Latin American countries.In this way, Latin America registered once again a growing participation in the international flow of direct investments. The evolution of direct Spanish investment in Latin America followed a path similar to that of wider international flows and, after the intense absorption of the first years of the Eighties, the rest of the decade registered a discreet attraction for investors which only began to change course from 1989 onwards with the reestablishment of the new phase of the economic cycle in the countries of the region.

Intellectual Capital: Perceptions of Productivity and Investment

Aristides Isidoro Ferreira

2011-03-01

Full Text Available This study focuses on the influence intellectual capital has on employees’ perceptions as related to both company investments and productivity levels. The data was obtained from 440 employees at 13 Portuguese companies. Both ANOVA and Regression Analysis were conducted in order to understand the impact three Intellectual Capital Scale components have on perceptions of investment and organizational productivity. Results show that companies with higher scores of Structural Capital have a lower perception of investment in human resources and research, as well as a higher perception of investment in marketing and sales. Moreover, employees of companies with higher Structural Capital scores also have higher perceptions of productivity. On the other hand, organizations with higher investment in Customer Capital tend to be associated with a lower perception of organizational productivity.

Does Foreign Aid Increase Foreign Direct Investment?

DEFF Research Database (Denmark)

Selaya, Pablo; Sunesen, Eva Rytter

  The notion that foreign aid and foreign direct investment (FDI) are complementary sources of capital is conventional among governments and international cooperation agencies. This paper argues that the notion is incomplete. Within the framework of an open economy Solow model we show...... that the theoretical relationship between foreign aid and FDI is indeterminate. Aid may raise the marginal productivity of capital by financing complementary inputs, such as public infrastructure projects and human capital investment. However, aid may also crowd out productive private investments if it comes...... in the shape of physical capital transfers. We therefore turn to an empirical analysis of the relationship between FDI and disaggregated aid flows. Our results strongly support the hypotheses that aid invested in complementary inputs draws in foreign capital while aid invested in physical capital crowds out...

An analysis is provided of returns for investment in power plants in China and India. Three sample investment scenarios are compared to illustrate the relative merits of each financing arrangement. The best returns would seem to be offered by a mix of debt and equity financing. The potential problem of gradual currency depreciation can be overcome by early cash payments. Foreign investment in China's power generation industry would be more readily forthcoming if easier access to debt finance were available. (UK)

Economic Efficiency and Investment Implementation in Energy Saving Projects

Directory of Open Access Journals (Sweden)

Venelin Terziev

2017-09-01

Full Text Available Investment in building thermoinsulation is a subject to appraisal for efficiency from the position of discounted cash flows taken specifically by energy saving. The appraisal of investment as optimal is attended by achieving the shortest term for investment implementation, the lowest investment outlays, the maximum total net value of energy savings, the shortest investment payback period. The complex application of the dynamic methods for appraising economic efficiency of an investment – net present value, internal rate of return, profitability index and discounted payback period, involves drawing of particular values which comparison definitely will show if this kind of investment is practically “attractive”. However, the question for significance weight of each of these indicators above in decision making for implementation a particular real investment still remains unsolved. This requires working out a system of criteria, priorities that can determine which of the indicators for economic efficiency of specific investment project will have the highest significance.

Forecasting Investment Risks in Conditions of Uncertainty

Andrenko Elena A.

2017-04-01

Full Text Available The article is aimed at studying the topical problem of evaluation and forecasting risks of investment activity of enterprises in conditions of uncertainty. Generalizing the researches on qualitative and quantitative methods for evaluating investment risks has helped to reveal certain shortcomings of the proposed approaches, to note in most of the publications there are no results as to any practical application, and to allocate promising directions. On the basis of the theory of fuzzy sets, a model of forecasting the expected risk has been proposed, making use of the Gauss membership function, which has certain advantages over the multi-angular membership functions. Dependences of investment risk from the parameters characterizing the investment project have been obtained. Using the formulas obtained, the total risk of investing in innovation project depending on the boundary conditions has been defined. As the researched target, index of profitability has been selected. The model provides the potential investors and developers with forecasting possible scenarios of investment process to make informed managerial decisions about the appropriateness of introduction and implementation of a project.

Investment accounting in building industry

Energy Technology Data Exchange (ETDEWEB)

Kuesgen, H.

1982-09-01

The methods of investment accounting are always required if, as it is usual for buildings, payments are not due once but repeatedly within a period of several years. These payments are presented in a payment model from which an informative and reliable total value of all costs and yields can be derived. The report deals nearly exclusively with the so-called dynamic investment accounting method as it records the payment procedures as to time much more exactly than the static investment accounting method. The problem of continually rising amounts of regular payments as e.g. energy prices can be better represented by the dynamic method. Therefore, the static methods have been dealt with only globally.

Renewable energy is one of the ways of reducing greenhouse gas emission. There is need for more investment in this sector. However, lack of stable regulatory framework and change in policy makes it unattractive to investors. International investment laws through its protections in investment agreement can help to mitigate risks considered by investors especially those with Build, Operate and Transfer (BOT) type of contracts.

Considerations on Optimal Financial Invest ment into Infrastructural Facilities

Institute of Scientific and Technical Information of China (English)

无

2002-01-01

The enlargement of government's investment into infrastructural construction is both a help medicine curing economic contraction and an effective measure to accumulate long-term economic growth.. However, the investment by finance into infrastructure also has a problem of optimization and reasonable selection. In view of market economic requirements, the policy direction of financial investment into infrastructural industries must be doing something at the expense of some other things. In the process of the adjustment and optimization of economic structure, state financial investment into infrastructural facilities has to first of all solve the problem of delimitating the best fields and selecting trades. As to the infrastructure facilities producing and selling pure public products, the development must be made by financial investment;As to the production fields of subpublic products, finance should ensure reasonable investment; As to the infrastructural facilities of pure privite production, finance should completely, in principle, pull out and let market supply. On this basis, selections should be made on best capital soureces and investment ways. The capital sources should be mainly from tax and regulational income and direct investment may be made. As to the production fields of most subpublic production, the best capital sources are national debt income and indirect investment may be made. In addition, the optimization of financial investment into infrastructural facilities must reform the managerial system of infrastructural facilities and raise investment efficiency. Only by scientifically selecting and arranging the financing ways and managerial system in investment fields,can the maximum economic efficiency and social welfare results be realized in carrying out financial investment into infrastructural facilities.

This paper investigates investment strategies that exploit the low-beta anomaly. Although the notion of buying low-beta stocks and selling high-beta stocks is natural, a choice is necessary with respect to the relative weighting of high-beta stocks and low-beta stocks in the investment portfolio. Our empirical results for US large-cap stocks show that this choice is very important for the risk-return characteristics of the resulting portfolios and their sensitivities to common risk factors.

Full Text Available The theoretical and methodological principles for assessing the investment attractiveness of the regions are the subject of the research. The aims of the research consist in improving the existing approach for measuring the level of investment attractiveness of territorial systems in the direction of taking into account the possible multicollinearity and determining the share of investment attractiveness factors in the aggregate indicator on the basis of calculated values of determination coefficients, which respectively provide to distinguish the priority directions in the formation of regional investment policy aimed at raising the level of investment attractiveness of regions of Ukraine. Methodology. The article deals with the research of theoretical and methodological approaches to the definition of investment attractiveness of Ukrainian regions by means of general scientific methods of analysis: systematization and generalization, induction, deduction. Results. To assess the investment climate in the regions of Ukraine, an improved existing approach for measuring the level of investment attractiveness of territorial systems is proposed in the direction of taking into account possible multicollinearity and determining the share of factors of investment attractiveness, which is based, in particular, on the selected indicators, in particular: the volume of direct foreign investments per capita (FORINV; per capita net exports (NETEXP; the number of economically active enterprises per 10 000 population (ENTRP; volumes of industrial production (PROM; population income (REV; volume of retail trade turnover per capita (TOV; volume of completed construction work (BUD. It is proved that the priority and intensity of influence on the indicator of investment into fixed capital per capita of factors of investment attractiveness varies for different regions of Ukraine, therefore, according to the conducted analysis, the investment attractiveness of the
