comments on the eoq model for deteriorating items with conditional trade credit linked to order quantity in the supply chain management abstract ouyang et al 2009 consider an economic order quantity eoq model for deteriorating items with a partially permissible delay in payments linked to order quantity basically their inventory model is practical but there are some defects from the logical viewpoints of mathematics in this paper the functional behaviors of the annual total relevant costs are explored by rigorous methods of mathematics a complete solution procedure is also developed to make up for the shortcomings of ouyang et al 2009 in numerical examples it is proved that the new solution procedure could avoid making wrong decisions and causing cost penalties

global feminization through flexible labor abstract the emphasis on structural adjustment and labor flexibility in both developing and industrialized economies is rapidly altering the nature of employment women are being substituted for men and many forms of work are being converted into the kinds of jobs traditionally geared to women international data on recent trends in female economic activity reveal that new types of labor data are needed to highlight the mechanisms of control over workers and the actual economic forms of vulnerability to which women are exposed the paper concludes by posing questions that challenge the traditional concerns of donors and policy makers in many developing countries

the optimal ordering policy in a dcf analysis for deteriorating items when trade credit depends on the order quantity abstract in this paper an inventory system for deteriorating items under the conditions of using the discounted cash flows dcf approach to the permissible to delay payment will be considered as a matter of fact the supplier usually is willing to provide the retailer a permissible delay of payments if the retailer orders a large quantity as a result we consider that the delay in payments depends on the quantity ordered that is when the order quantity is less than that at which the delay in payments is permitted the payment for the item must be made immediately otherwise the fixed trade credit period is permitted this paper incorporates all concepts of a dcf approach and the trade credit linked to ordering quantity and develops a new inventory model for deteriorating items to generalize jaggi and aggarwal int j prod econ 34 1994 151

optimal production lot with imperfect production process under permissible delay in payments and complete backlogging abstract the traditional economic production quantity epq model assumes that the production products are all perfect it is not always true in the real production system due to imperfect production process or other factors imperfect quality items may be produced furthermore it is well known that the total production inventory costs can be reduced by reworking the imperfect quality items produced with a relatively smaller additional reworking and holding costs in addition the permissible delay in payments offered by the supplier is widely adopted in the practical business market in this study we explore the effects of the reworking imperfect quality items and trade credit on the epq model with imperfect production processes and complete backlogging a mathematical model which includes the reworking and shortage costs interest earned and interest charged is presented besides an arithmetic geometric mean inequality approach is employed and an algorithm is developed to find the optimal production policy furthermore some numerical examples and sensitivity analysis are provided to demonstrate the proposed model

input demand under yield and revenue insurance previous studies disagree on the effects of insurance on fertilizer application rates the effect of increased fertilizer on the probability of low yields primarily determines whether fertilizer and insurance are substitutes or complements we estimate conditional distributions of corn yields to determine if the technical relationship between yields and fertilizer supports the hypothesis that insurance increases optimal application rates our results indicate no support for this hypothesis at all nitrogen fertilizer rates and reasonable levels of risk aversion nitrogen fertilizer and insurance are substitutes suggesting that those who purchase insurance are likely to decrease nitrogen fertilizer applications

an eoq model with partial backordering and advance payments for an evaporating item abstract in the classic economic order quantity model the purchasing cost of an order is paid at the time of its receipt in some cases retailers ask purchasers to pay all or a fraction of the purchasing cost in advance and may allow them to divide the prepayment into several equal sized parts in this paper an economic order quantity model for an evaporating item with partial backordering and partial consecutive prepayments is developed with a real case study of a gasoline station real numerical examples illustrate the proposed model and the solution method

financial crisis gender and power an analytical framework abstract this paper begins to remedy the neglect of gender aspects of financial crises by exploring a suggestive microfoundational model of unequal gender power and cost bearing in a borrower household this model shows that financial market liberalization can assess women s access to formal sector employment and encourage the growth of household credit both for a household enterprise and for the acquisition of labor saving household assets the price of these gains however is greater household risk because of greater cash flow dependence and financial fragility a financial crisis can force the household to bear heavier adjustment costs than would otherwise be felt and these costs may well be borne disproportionately by women who become more economically vulnerable as a result

integrating deterioration and lifetime constraints in production and supply chain planning a survey abstract items with short lifetimes that are subject to deterioration are important in the business world research has a long tradition in integrating deterioration and value loss effects into mathematical models for inventory planning and control where such effects are understood as a general loss or shrinkage of inventory however there has been little work in the modeling of lifetime restrictions of items to prevent wastage and disposals especially in a dynamic planning context globalization and other trends extend the consideration of single companies to whole supply chains implying increased coordination and information needs this is important as planning decisions impact lead times and thus the quality of items in the whole supply chain products that exceed their useful lifetime can impose high costs due to inventory loss or the need to rework them this implies increased utilization of scarce resources e g machine time metals and or energy thereby increasing co 2 levels we survey the state of the art regarding depreciation effects and the modeling of lifetime constraints as well as a classification of models following business planning functions of the value chain a critical evaluation of approaches and their limitations is provided highlighting directions for future research

optimal order policy for deteriorating items with inflation induced demand abstract this paper presents the optimal inventory replenishment policy of deteriorating items under inflationary conditions using a discounted cash flow dcf approach over a finite planning horizon a dcf approach permits a proper recognition of the financial implication of the opportunity cost and out of pocket costs in inventory analysis it also permits an explicit recognition of the exact timing of cash flows associated with an inventory system the demand rate is assumed to be a function of inflation shortages are allowed and completely backlogged optimal solution for the proposed model is derived and the effects of deterioration and inflation on the optimal inventory replenishment policy are studied with the help of numerical example

decoupled farm payments and the role of base acreage and yield updating under uncertainty we analyze the coupling effect of expectations about base acreage and yield updating in future farm policy on production decisions in the presence of price yield and policy uncertainty for a risk averse farmer producing a single crop the farmer receives market revenue and government payments using stochastic dynamic programming optimum decisions under present value calculations positively link current acreage and fertilizer decisions to future government payments through expected updates of base acreage and yield in the future regime moving from a zero probability of updating to a probability of one increases optimum acreage and yield by 6 25 and 0 134 respectively copyright 2010 oxford university press

review of inventory systems with deterioration since 2001 abstract this paper presents an up to date review of the advances made in the field of inventory control of perishable items deteriorating inventory the last extensive review on this topic dates back to 2001 goyal s k and giri b c recent trends in modeling of deteriorating inventory european journal of operational research 134 1 16 since then over two hundred articles on this subject have been published in the major journals on inventory control indicating the need for a new review we use the classification of goyal and giri based on shelf life characteristics and demand characteristics contributions are highlighted by discussing main system characteristics including price discounts backordering or lost sales single or multiple items one or two warehouses single or multi echelon average cost or discounted cash flow and payment delay

optimal retailer s replenishment decisions in the epq model under two levels of trade credit policy abstract the main purpose of this paper is to investigate the optimal retailer s replenishment decisions under two levels of trade credit policy within the economic production quantity epq framework we assume that the supplier would offer the retailer a delay period and the retailer also adopts the trade credit policy to stimulate his her customer demand to develop the retailer s replenishment model under the replenishment rate is finite furthermore we assume that the retailer s trade credit period offered by supplier m is not shorter than the customer s trade credit period offered by retailer n m n since the retailer cannot earn any interest in this situation m n based upon the above arguments this paper incorporates both chung and huang k j chung y f huang the optimal cycle time for epq inventory model under permissible delay in payments international journal of production economics 84 2003 307 318 and huang y f huang optimal retailer s ordering policies in the eoq model under trade credit financing journal of the operational research society 54 2003 1011 1015 under above conditions in addition we model the retailer s inventory system as a cost minimization problem to determine the retailer s optimal replenishment decisions then three theorems are developed to efficiently determine the optimal replenishment decisions for the retailer we deduce some previously published results of other authors as special cases finally numerical examples are given to illustrate the theorems obtained in this paper then as well as we obtain a lot of managerial insights from numerical examples

using consumption and asset return data to estimate farmers time preferences and risk attitudes the generalized expected utility model is fitted to u s farm data to estimate farm operator s time preferences and risk attitudes the estimated farmer s utility parameters are quite reasonable and exhibit high accuracy the forward looking expected utility model is soundly rejected in favor of the generalized expected utility paradigm importantly the generalized expected utility model is also found to fit the data better than the myopic model typically used to study agricultural production under risk finally u s farmers relative aversion to risk appears to have diminished significantly over time

the effects of policy expectations on crop supply with an application to base updating we develop a dynamic model to assess the effects of policy expectations on crop supply and illustrate the approach with estimates of the effects of base updating in u s crop programs for corn and soybeans in the corn belt the effect of base updating is relatively small because relevant crop alternatives are subject to similar policies and the alternatives are substitutes in production increasing acreage of one program crop to capture future payments from base updating reduces future payments from the alternative crop we also use our model to assess the effect of base updating on acreage response to prices

emerging stock markets portfolio capital flows and long term economie growth micro and macroeconomic perspectives abstract the paper examines two major components of financial liberalization stock market development and portfolio capital flows in the context of less developed countries the paper considers microeconomic and macroeconomic perspectives on their implications for long term development and economic growth it concentrates on 1 a the role of stock markets in financing corporate growth 2 b the implications of stock market volatility for resource allocation and productive efficiency and 3 c the interactions between the foreign exchange and stock markets in the context of economic shocks its policy recommendations are that ldcs should promote bank based systems influence the scale and composition of capital inflows and prevent a market for corporate control from emerging

financial liberalisation stockmarkets and economic development abstract during the 1980s and 1990s many developing countries dcs have been engaged in far reaching reforms of their financial systems liberalising them and making them more market oriented this liberalisation involving inter alia financial de repression has been inspired partly by the work of the mckinnon 1973 and shaw 1973 m s school this paper suggests that in addition to financial de repression there has been a major new element in the development of dc financial systems in recent years the establishment and fast expansion of stockmarkets these markets have played a key role in the internal as well as external financial liberalisation processes in leading dcs further the paper finds that the actual behaviour of these markets in many countries has led to outcomes which undermine the effects of the higher real interest rates arising from financial de repression

modeling the reforms of the common agricultural policy for arable crops under uncertainty the size of the insurance and wealth effects of a change in the common agricultural policy cap for arable crops is estimated the impact of price uncertainty is accounted for in the specific decision making structure of the european union eu arable crop producers under nonlinear mean variance risk preferences a system of output supply input demand and land allocation equations is estimated on a sample of italian specialized arable crop farms the simulation of the impact of the recent reforms confirms that farmers output responses are consistently affected by the size of the insurance and wealth effects

an inventory model with deteriorating items under inflation when a delay in payment is permissible abstract this study develops an inventory model for initial stock dependent consumption rate when a delay in payment is permissible in the inventory model shortages are not allowed the effect of the inflation rate deterioration rate initial stock dependent consumption rate and delay in payment are discussed in the study mathematical models are also derived under two different circumstances i e case i the credit period is less than or equal to the cycle time for settling the account and case ii the credit period is greater than the cycle time for settling the account besides expressions for an inventory system s total cost are derived for these two cases moreover a computational procedure and gino lasdon et al acm transactions mathematical software 4 1978 34 50 are proposed to obtain the optimal order size and cycle time the results can help managers determine the optimal total cost finally a numerical example demonstrates the applicability of the proposed model

international capital flows identifying the gender dimension abstract this paper explores the main issues involved in examining the gender impact of international capital flows to developing countries it argues that at the macroeconomic level women lose more than men from slow and or unstable economic growth financial crises and meltdowns and even more so the longer and deeper the economic downturn because without a social security system the family and women have many additional burdens women should formulate an agenda of their own with respect to international monetary reform and some proposals are outlined in this respect including those involving capital controls

an eoq model under retailer partial trade credit policy in supply chain abstract the main purpose of this paper is to investigate the retailer s inventory policy under two levels of trade credit to reflect the supply chain management situation in this paper we assume that the retailer has the powerful decision making right so we extend the assumption that the retailer can obtain the full trade credit offered by the supplier and the retailer just offers the partial trade credit to his her customer then we investigate the retailer s inventory system as a cost minimization problem to determine the retailer s optimal inventory policy under the supply chain management two easy to use theorems are developed to efficiently determine the optimal inventory policy for the retailer we deduce some previously published results of other researchers as special cases finally numerical examples are given to illustrate the theorems and obtain a lot of managerial phenomena

what can explain the apparent lack of international consumption risk sharing recent research in international business cycles finds that international consumption comovements do not match the risk sharing predictions of standard complete markets models in this paper i ask whether two different types of explanations can help explain this result 1 nonseparabilities between tradables and nontradable leisure or goods and 2 the effects of capital market restrictions on consumption risk sharing i find that risk sharing cannot be resolved by either explanation alone however when i allow for both nonseparabilities and certain market restrictions risk sharing among unrestricted countries cannot be rejected this evidence suggests that a combination of these two effects may be necessary to explain consumption risk sharing across countries

production incentives from static decoupling land use exclusion restrictions many agricultural support payments are based on past production with restrictions on how land may currently be used when support payments to field crops are analyzed in a static framework they do not directly impact current production decisions however over time as relative profits change these payments affect current output the payments may keep land in less profitable production of program crops through restrictions prohibiting potentially more profitable endeavors such as cultivating fruits and vegetables these payments have the potential to lead to production and trade distortions similar in magnitude to the distortions associated with direct production subsidies

optimal ordering policies under conditions of extended payment privileges this paper develops optimal order quantities for firms that are offered a one time opportunity to delay payment for an order of a commodity such delayed payments result in a reduction of the effective purchase cost which is a function of the return available on alternative investments the number of units of the commodity ordered and the length of the extended period optimal order quantities are developed for extended payment privileges that occur at a reorder point of between reorder points six suppliers extended payment scenarios are evaluated a simulation analysis is conducted to determine the sensitivity of derived models to changes in the various input parameters the simulation with realistic parameter values reveals that the additional discounted order quantity is insensitive to large changes in the ordering cost and unit price sensitive to changes in the carrying cost and return rate of funds but without significantly affecting the total cost and extremely sensitive to the annual demand

a century of evolution from harris s basic lot size model survey and research agenda abstract determining the economic lot size has always represented one of the most important issues in production planning this problem has long attracted the attention of researchers and several models have been developed to meet requirements at minimum cost in this paper we explore and discuss the evolution of these models during one hundred years of history starting from the basic model developed by harris in 1913 up to today following harris s work a number of researchers have devised extensions that incorporate additional considerations the evolution of eoq theory strongly reflects the development of industrial systems over the past century here we outline all the research areas faced in the past by conducting a holistic analysis of 219 selected journal papers and trying to give a comprehensive view of past work on the eoq problem finally a new research agenda is proposed and discussed

how much do decoupled payments affect production an instrumental variable approach with panel data how much decoupled payments such as direct payments in the u s affect agricultural production remains an open empirical question with implications for policy using data from multiple years of the census of agriculture we exploit a provision of the 2002 farm act that departed from previous policy by making oilseeds eligible for direct payments thus increasing payments to areas that historically produced more oilseeds our instrumental variable estimates in contrast to ols estimates suggest that changes in payments over the period 2002 to 2007 had little effect on aggregate production at the zip code level copyright 2012 oxford university press

the effects of farm subsidies on farm exports in the united states we estimate the elasticity of u s farm exports to u s farm subsidies using a gravity model of state level farm exports to 100 major trading destinations for the period 1999 to 2011 our identification strategy exploits the within state variation that is free of endogeneity bias in the levels and trends of farm subsidies and farm exports we find that a 1 decrease in farm subsidies would reduce u s farm exports by 0 40 per annum this equivalently means that the complete abolishment of the farm subsidy program would reduce u s farm exports by approximately 15 3 billion per year importantly we document robust evidence that amber box subsidy programs such as counter cyclical payments and marketing loan gains have the strongest effect on farm exports while green box subsidy payments such as direct payments have negligible effects finally subsidy payments affect exports only in agricultural commodities not in livestock our subsidy elasticity estimates are statistically significant stable and economically meaningful and are vitally needed by u s and global policymakers in the face of critical domestic and international developments

feminization of the labor force the effects of long term development and structural adjustment abstract using crosscountry data pooled for 1985 and 1990 we analyze the relationship between women s share of the labor force and the processes of long term economic development and macroeconomic changes associated with structural adjustment we find that the relationship between long term development and women s share of the labor force is u shaped controlling for the feminization u we also find that structural adjustment policies have led to an increase in feminization of the labor force via worsening income distribution and increased openness

are countries with official international restrictions liquidity constrained abstract in this paper i empirically examine consumption smoothing behavior across a broad group of countries using a unique data set that indicates whether residents in a country face an official government restriction i then ask whether the ex ante consumption movements among restricted countries differ from those of unrestricted countries to gauge the departure from standard consumption smoothing i use the campbell and mankiw consumption income and interest rates reinterpreting the time series evidence in o j blanchard and s fischer eds nber macroeconomics annual 1989 mit press cambridge ma 1989 and the response of consumption to income a cross country investigation european economic review 35 723 756 1991 approach of regressing consumption growth on income growth and instrumenting with lagged variables interestingly i find that consumption growth for residents in countries that impose international restrictions have a significantly higher coefficient on income growth than do residents in countries without those restrictions thus a greater proportion of consumers facing international restrictions appear to act as though they are liquidity constrained according to the campbell and mankiw approach i also discuss alternative interpretations that do not depend upon liquidity constraints

long term trends in the world economy the gender dimension abstract this paper considers the implications of long term trends in the international economy for the relative employment and income of men and women in developed and developing countries we find that given a persistent gender division of labor mass unemployment in the north is due to different forces operating on men and women the rate of growth of men s jobs has fallen because of deindustrialization but men have not withdrawn from the labor force at a comparable rate women have been entering the labor force in feminized jobs at a faster rate than they have been created in the south women have largely taken traditionally feminized jobs in the labor intensive export oriented growing manufacturing sectors in latin america entry has been largely in the service sector men have been losing jobs in agriculture and domestic manufacturing the paper proposes that the optimal solution to the mass unemployment problem in the north as well as in the south and the apparent competition for jobs between the north and the south and between men and women lies in achieving a trend increase in the growth rate of oecd and world aggregate demand and output but such a trend rise in the long term rate of growth of demand would only be possible if there were new cooperative institutional arrangements within and between countries in such arrangements women need to have an important independent role

the role of the state in financial markets this paper reexamines the role of the state in financial markets and identifies seven major market failures that provide a potential rationale for government intervention in practice government interventions in capital markets even in industrial countries have been pervasive the paper provides a taxonomy of those interventions with respect to both the objectives they serve and the instruments they employ there is a role for the government in financial markets but the success of government interventions has been mixed it is important that interventions be well designed the paper sets out principles for government regulatory interventions and applies them to prudential regulation it then examines three other areas of intervention directed credit finanical repression and competition policy and identifies circumstances in which some amount of financial repression may actually be beneficial

the effects of the east asian crisis on the employment of women and men the philippine case abstract this paper analyzes the differential employment impacts on women and men brought about by the east asian crisis and the preceeding periods of boom bust cycles and increased openness it is found that the growth period in the second half of the 1980s favored male employment more than female employment the economic decline due to the east asian crisis reversed this process and increased male unemployment more than female unemployment especially in urban areas despite a more rapid displacement of women workers from the manufacturing sector one contributing factor to this is the resilience of the community social and personal services and wholesale and trade sector during the crisis evidence such as increased female labor force participation and longer working hours for women relative to men during the crisis points to increased female employment and work hours in the labor market as a major coping mechanism during the crisis the paper therefore argues that the boom bust cycles in the macroeconomy are not gender neutral and contributes to increasing earnings and labor time disparities between women and men to the detriment of the women

economic order quantity under conditionally permissible delay in payments abstract within the economic order quantity eoq framework the main purpose of this paper is to investigate the retailer s optimal replenishment policy under permissible delay in payments all previously published articles dealing with optimal order quantity with permissible delay in payments assumed that the supplier only offers the retailer fully permissible delay in payments if the retailer ordered a sufficient quantity otherwise permissible delay in payments would not be permitted however in this paper we want to extend this extreme case by assuming that the supplier would offer the retailer partially permissible delay in payments when the order quantity is smaller than a predetermined quantity under this condition we model the retailer s inventory system as a cost minimization problem to determine the retailer s optimal inventory cycle time and optimal order quantity three theorems are established to describe the optimal replenishment policy for the retailer some previously published results of other researchers can be deduced as special cases finally numerical examples are given to illustrate all these theorems and to draw managerial insights

the optimal retailer s ordering policies for deteriorating items with limited storage capacity under trade credit financing abstract under permissible delay in payments all previously published models implicitly assumed that the supplier would offer the retailer a delay period but the retailer would not offer the trade credit period to his her customer huang 2003 journal of the operational research society 54 1011 1015 developed a retailer s replenishment model to reflect the real life situations by assuming that the retailer also adopts the trade credit policy to stimulate his her customer demand in huang s model it is assumed that the goods are not perishable and the storage capacity is unlimited based upon the above argument we propose a two warehouse inventory model for deteriorating items under permissible delay in payments three theorems are developed to determine the optimal cycle time and numerical examples are given to illustrate these theorems finally the results in this paper generalize the results presented by huang 2003 journal of the operational research society 54 1011 1015

the production effects of agricultural income support policies under uncertainty this analysis decomposes the production impacts of income support programs into wealth insurance and coupling effects under the usual assumptions about preferences the wealth and insurance effects of many support programs increase optimal input levels even for supposedly decoupled programs if the program is coupled in the usual sense then all three effects often act in the same direction it is concluded that studies of trade and domestic policy reform in stochastic environments should consider insurance and wealth effects the derivative conditions required to obtain results are also subjected to scrutiny simulations for an iowa corn producer confirm the comparative statics

optimal trade credit and lot size policies in economic production quantity models with learning curve production costs abstract in reality a seller e g a supplier or a manufacturer frequently offers his her buyers trade credit e g permissible delay in payment trade credit reduces the buyer s holding cost of inventory and hence attracts new buyers who consider it to be a type of price reduction on the other hand granting trade credit also increases the seller s opportunity cost i e the loss of capital opportunity during the credit period and default risk i e the event in which the buyer will be unable to make the required payments on his her debt obligation in addition it is a well known fact of learning by doing that production cost of a new product declines by a factor of from 10 to 50 percent each time the accumulated production volume doubles therefore we propose an economic production quantity model from the seller s prospective to determine his her optimal trade credit period and production lot size simultaneously in which i trade credit increases not only sales but also opportunity cost and default risk and ii production cost declines and obeys a learning curve phenomenon then the necessary and sufficient conditions to obtain the seller s optimal trade credit and order quantity are derived finally we use some numerical examples to illustrate the theoretical results and to provide some managerial insights

portfolio capital flows hot or cold a distinction is often made between short term and long term capital flows the former are deemed unstable hot money and the latter are deemed stable cold money using time series analysis of balance of payments data for five industrial and five developing countries we find that in most cases the labels short term and long term do not provide any information about the time series properties of the flow in particular long term flows are often as volatile as short term flows and the time it takes for an unexpected shock to a flow to die out is similar across flows long term flows are also at least as unpredictable as short term flows and knowledge of the type of flow does not improve the ability to forecast the aggregate capital account copyright 1995 by oxford university press

effects of inflation and time value of money on an inventory model with linear time dependent demand rate and shortages abstract in the present paper an attempt has been made to investigate the effects of inflation and time value of money on an inventory model with linear time dependent demand rate shortages are allowed in this model the model developed in this article is a finite horizon t si policy inventory model to the best of the authors knowledge such type of inventory model has not been considered earlier a numerical example has also been given to illustrate the developed model

the impact of coupled and decoupled government subsidies on off farm labor participation of u s farm operators with the 1996 farm act the united states introduced payments that were designed to be decoupled labor allocation choices are likely to be affected by receipt of payments and income from off farm jobs has been the major source of income for most farm households for sometime this article examines whether the 1996 change has affected the off farm labor participation of farm households we conclude that the observed increase in off farm participation of farm operators who received payments was not the result of the 1996 policy change government payments whether coupled or decoupled have a negative effect on off farm labor participation

do counter cyclical payments in the 2002 us farm act create incentives to produce analytical results in the literature suggest that counter cyclical payments create risk related incentives to produce even if they are decoupled under certainty hennessy d a 1998 the production effects of agricultural income support polices under uncertainty am j agric econ 80 46 57 this paper develops a framework to assess the risk related incentives to produce created by commodity programmes like the loan deficiency payments ldps and the counter cyclical payments ccps in the 2002 us farm act because ccps are paid based on fixed production quantities they have a weaker risk reducing impact than ldps the latter have a direct impact through the variance of the producer price distributions while the impact of ccps is due only to the covariance between the ccp and the producer price distributions the methodology developed by chavas j p holt m t 1990 acreage decisions under risk the case of corn and soybeans am j agric econ 72 3 529 538 is applied to calculate the appropriate variance covariance matrix of the truncated producer price distributions under the 2002 farm act risk premia are computed showing that the risk related incentives created by ccps are significant and do not disappear for levels of production above the base production on which ccps are paid

food vs fiber an analysis of agricultural support policy in turkey the present study evaluates the effects of agricultural policies on farm land allocation the analysis is applied to turkey a country where a persistent gap between rural income and urban income has motivated governments to enact policies that support farm income this paper evaluates two sets of policy instruments output support which increases farm revenue from specific crops and input support which subsidizes particular farm inputs it also investigates the effects of agricultural policy on farmers incentive to produce fiber cotton versus food corn and other foods using farm level data from two regions of turkey the analysis finds that input supports have had stronger effects on land allocation than output supports it also shows the presence of significant substitution effects across crops with the subsidizing of cotton having a significant negative effect on the incentive to grow food crops this provides useful insights into the economic tradeoff between food and fiber in the design of agricultural policy and its effects on a country s food security

an eoq model with deteriorating items under inflation when supplier credits linked to order quantity abstract this study proposes an inventory model under a situation in which the supplier provides the purchaser a permissible delay of payments if the purchaser orders a large quantity shortages are not allowed and the effect of the inflation rate deterioration rate and delay in payment are discussed as well as a result in this paper we establish an eoq model for deteriorating items under inflation when the supplier offers a permissible delay to the purchaser if the order quantity is greater than or equal to a predetermined quantity we then characterize the optimal solution and provide an easy to use algorithm to find the optimal order quantity and replenishment time finally some numerical examples are given to illustrate the theoretical results and made the sensitivity analysis of parameters on the optimal solutions

stackelberg solution in a vendor buyer supply chain model with permissible delay in payments abstract in practice vendors or sellers often offer their buyers a fixed credit period to settle the account the benefits of trade credit are not only to attract new buyers but also to avoid lasting price competition on the other hand the policy of granting a permissible delay adds not only an additional cost but also an additional dimension of default risk to vendors in this paper we will incorporate the fact that granting a permissible delay has a positive impact on demand but negative impacts on both costs and default risks to establish vendor buyer supply chain models then we will derive the necessary and sufficient conditions to obtain the optimal solution for both the vendor and the buyer under non cooperative stackelberg equilibrium finally we will use two numerical examples to show that 1 granting a permissible delay may significantly improve profits for both the vendor and the buyer 2 the sensitivity analysis on the optimal solution with respect to each parameter and 3 the comparisons between nash and stackelberg solutions

capitalization of the single payment scheme into land value generalized propensity score evidence from the eu this paper estimates the capitalization of the single payment scheme sps into land values the theory suggests a nonlinear and discontinuous relationship between the sps and land rents in empirical analysis we employ unique farm level panel data and apply the generalized propensity score matching approach our estimates suggest a 6 to 10 sps capitalization rate on average in the european union the nonfarming landowners gains from the sps are only 4 however there is a large variation in the capitalization rate for different sps levels and between different member states 3 to 94

capital account liberalisation and poverty how close is the link the literature on the theoretical and empirical aspects of the relationship between finance and economic growth is both substantial and extensive the same cannot be said on the relationship between financial development and poverty reduction an equally important aspect in this study we visit the theoretical arguments and conduct an empirical analysis of the relationship between the capital account dimension of financial liberalisation and poverty for developing countries for the period 1985 2005 in particular we employ the system gmm technique to test whether capital account liberalisation has helped alleviate poverty and also whether the extent to which capital account liberalisation affects poverty depends on the quality of institutions we also use ols and iv techniques to verify our findings our findings indicate that there is no statistically significant relationship between the degree of capital account liberalisation during the period and the poverty rate developing countries with higher institutional quality have lower poverty rates but the effect has low statistical significance a higher degree of capital account liberalisation is associated with a lower income share for the poor

supply response to countercyclical payments and base acre updating under uncertainty an experimental study we design an experiment to simulate how people make agricultural production decisions under three policy scenarios each incorporating direct payments dps a price uncertainty without countercyclical payments ccps b price uncertainty with ccps and c price uncertainty ccps and uncertainty regarding base acreage updating results are the ccp program and perceived possibility of future base updating created incentives for subjects to invest more in program base crops despite payments being decoupled from current production decisions those choosing to reduce revenue risk by increasing plantings of base crops may face reduced incomes suggesting the efficiency of crop markets may be diminished

the impact of decoupled payments on farm choices conceptual and methodological challenges abstract in this paper we review the methodological framework for analysing decoupled payments in models of agricultural production market and technological uncertainty farm efficiency credit constraints farm household choices involving extra agricultural decisions policy uncertainty and long run impact of decoupling on investment and land values are the relevant issues that should be pursued by methodological and empirical analysis future research should refine the analysis of decoupled payments mainly trying to provide results that can be useful for policy simulation to bridge the gap between analysis at the individual level and sector policy models

monetization financial liberalization and economic development barter sector in 1954 55 the monetized sector contributed 69 to the net national product of india the share of the monetized sector increased to 78 6 of the net national product by 1974 75 during this period the explicit objective of monetary policy in india was to help accelerate the pace of economic development in an environment of reasonable price stability there are several versions of the financial liberalization hypothesis but the one put forward by ronald mckinnon is chosen here because of its succinctness and easy amenability to empirical verification 2 mckinnon s theory in essence deals with the effect of financial liberalization on the accumulation of capital through a policy of high real interest rates this formulation has been made operational by estimating the response of real demand for money balances and private investment to alternative rates of return under the implicit assumption that these are the only two alternative forms of assets held by the private sector 3 all this is predicated on the assumption that the effective limitation on the rate of real capital formation is the supply of real savings and not the inadequate willingness to invest most underdeveloped countries have a significant barter sector a reduction in the share of the barter sector can help to further accelerate the accumulation of capital in a barter system a good share of the factors of production is tied up in distribution away from production to achieve the double coincidence required in such a system with the

financial development and economic growth views and agenda this critique argues that the preponderance of theoretical reasoning and empirical evidence suggests a positive first order relationship between financial development and economic growth the body of work would push even most skeptics toward the belief that the development of financial markets and institutions is a critical and inextricable part of the growth process and away from the view that the financial system is an inconsequential sideshow responding passively to economic growth many gaps remain however and the paper highlights areas in acute need of additional research

growth and poverty evidence for developing countries in the 1980s abstract measures of consumption poverty for a sample of developing countries in the 1980s respond elastically to changes in mean consumption although there is a high variance in poverty outcomes at a given rate of growth there is no sign of systematic effects of growth on inequality
