the optimal taxation of fiat money in search equilibrium this paper investigates the link between welfare and the taxation of money in the context of a general equilibrium search model where decentralized trading motivates the use of fiat money since buyers with money must invest effort or search intensity to contact sellers with goods a natural trading externality arises given a sufficiently productive economy search efforts will be too low relative to social efficiency this provides a welfare improving role for policies which tax money balances the nature of this role is explored and its implications for optimal monetary policy discussed copyright 1995 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

a theory of commerce abstract the theory of commerce advanced here captures prominent features of retail trade large employment congestion effects anonymous posted prices and quantity discounts this theory is built around a directed search model where buyers preferences are private information the analytical solution is easily inserted in a neoclassical growth framework in this framework the parameters of retail trade are calibrated using commercial margins and employment welfare properties depend on the sellers ability to charge two tier prices with two tier prices the directed search equilibrium is efficient otherwise it is not this contrasts with the full information benchmark where directed search is always efficient

financial performance analysis of ontario canada credit unions an application of dea in the regulatory environment abstract models are developed to detect weaknesses in credit unions in ontario canada so that potential financial failures can be predicted four data envelopment analysis dea models are presented and compared with the equity to asset ratio and with the government regulator s extensively modified z score model the equity asset ratio is shown to provide as good a prediction of failure as any of the other models and is not improved upon by the much more complex z score model the best dea model provides results comparable to the equity asset ratio when a slack adjusted efficiency score is used to measure efficiency particularly for credit unions with larger asset sizes however dea also provides indications of where opportunities lie for improvements by weak units by providing specific information relevant to managers hence for each credit union comparison is made with a peer group of efficient entities that the inefficient institution s management can emulate to improve their performance

variations in farm consumption and their relationship to income an empirical investigation of illinois farm households empirical tests of household consumption have yielded mixed results regarding the validity of the life cycle permanent income lcpi hypothesis a significant problem with such studies is the diffi

output prices and the velocity of money in search equilibrium a monetary search model with match specific preferences and traded quantities is analyzed to assess how aggregate output the price level and the velocity of money are affected by various forms of technological change changes in the productive technology lead to output and prices moving in opposite directions but provide no prediction for monetary velocity the matching technology directly affects monetary velocity and output but has little impact on prices transactions technologies which affect the fixed cost of trading are ambiguous with respect to comovements of output and prices but systematically impact velocity

agricultural price instability a survey of competing explanations and remedies there are two explanations for agricultural price dynamics one follows cobweb logic and models fluctuations driven by expectation errors but emphasises that these expectations create complex dynamics and possibly chaos the other stems from the rational expectations tradition of dynamics driven by real shocks the empirical evidence tends to support the latter but is not conclusive the rational expectations model generates an optimal dynamic path from which no improvement can be expected from public intervention however if we take account of all the potential market failures in agricultural markets and especially in developing countries this conclusion might require some qualifications although an appropriate policy design for stability has still to be achieved this paper surveys the positive and normative literature on agricultural prices highlighting empirical evidence and identifying remaining unresolved issues

competitive search equilibrium in monetary economies abstract competitive search was recently introduced in monetary economics by rocheteau and wright money in search equilibrium in competitive equilibrium and in competitive search equilibrium econometrica 73 2005 175 203 we extend their work by eliminating the restriction that the fees market makers charge to enter a submarket must be either non negative or identical for buyers and sellers without this restriction buyers pay a positive fee to enter the submarket they visit and nothing else when they meet a seller sellers are remunerated by the market makers from the entry fees collected from the buyers this trading arrangement allows buyers to perfectly predict their expenses so the opportunity cost of holding idle money balances is eliminated

ex ante consumer welfare evaluation in cost benefit analysis abstract public projects and policies are normally evaluated ex ante i e while consumers may still be uncertain about future prices income levels interest rates and preferences this paper extends the theory of ex ante consumer welfare evaluation by developing a 2 period model with multiple sources of uncertainty it provides insights into the influence of temporal uncertainty on the empirical measurement of ex ante willingness to pay

new microfoundations for the aggregate matching function empirical studies of the aggregate labor market matching function have favored a cobb douglas functional form for which there are no microfoundations in the existing literature i present a new model for the matching process based on a telephone line poisson queuing process which unlike other microeconomic approaches can be integrated directly into standard theoretical search models this implies a ces matching function approximately cobb douglas when search costs are approximately linear the model allows empirical estimates of matching function parameters to be interpreted in terms of the costs and benefits of search

welfare analysis and intertemporal substitution abstract this paper explores the structure of welfare comparisons when direct utility is weakly separable over time the lifetime welfare effect of a reform is then the sum of atemporal hicksian variations and intertemporal variations reflecting intertemporal substitution these latter are shown to be of only second order importance in lifetime welfare comparisons approximations to the intertemporal variations when preferences are intertemporally additive are derived pointing to the welfare significance in this context of not only the intertemporal elasticity of substitution but also within period income effects numerical examples illustrate the analysis and suggest possible orders of magnitude

competitive search equilibrium in this paper i construct an equilibrium for markets with frictions which is competitive in the sense that all agents are price takers and maximize utility subject to a set of market parameters i show that the equilibrium allocation is socially optimal i also show how the competitive search equilibrium can be achieved if employers with vacancies can advertise publicly the wages they pay

job destruction and propagation of shocks this paper considers propagation of aggregate shocks in a dynamic general equilibrium model with labor market matching and endogenous job destruction cyclical fluctuations in the job destruction rate magnify the output effects of shocks as well as making them much more persistent interactions between capital adjustment and the job destruction rate play an important role in generating persistence propagation effects are shown to be quantitatively substantial when the model is calibrated using job flow data incorporating costly capital adjustment leads to significantly greater propagation

assessing the economic costs of a foot and mouth disease outbreak on brittany a dynamic computable general equilibrium analysis abstract outbreaks of animal diseases such as foot and mouth disease fmd are of great concern for agriculture in this paper we quantify the potential dynamic impacts of such a disease on brittany a french region with an important livestock sector in order to do this we develop a dynamic computable general equilibrium model that allows us to measure the impacts on the livestock sectors and downstream food industries we study the impacts of a fmd outbreak including the culling infected animals a temporary decline in demand and restrictions on movements of live animals and meats during the fmd outbreak period our results show that economic losses following this disease are spread over many periods even with a one time shock we also find that the impacts on the various primary sectors and downstream food sectors are quite different depending on their initial trade position our general equilibrium results show the great incidence of potential constraints affecting factor markets capital and wage constraints severely increase the aggregate costs of such disease these results challenge the definition of a simple efficient management policy for this disease

search theoretic models of the labor market a survey we survey the literature on search theoretic models of the labor market we show how this approach addresses many issues including the following why do workers sometimes choose to remain unemployed what determines the lengths of employment and unemployment spells how can there simultaneously exist unemployed workers and unfilled vacancies what determines aggregate unemployment and vacancies how can homogeneous workers earn different wages what are the tradeoffs firms face from different wages how do wages and turnover interact what determines efficient turnover we discuss various modeling choices concerning wage determination and the meeting process including recent models of directed search

income risk and farm consumption behavior abstract using panel data from illinois grain farmers a direct test of the relationship between income risk and farm consumption behavior is conducted the estimation results indicate that income risk significantly affects farm consumption and the results are robust using alternative risk measures this finding casts doubt on the relevance of the conventional life cycle permanent income hypothesis which implies that risk has no effect on consumption

testing theories of consumption behavior using information on aggregate shocks income seasonality and rainfall in rural india we develop an integrated framework for testing theories of consumption behavior by examining how agricultural households in rural india respond to anticipated and unanticipated seasonal income fluctuations using information on village level rainfall surprises we estimate idiosyncratic unanticipated income shocks by allowing weather risk to impact households differently depending on observable characteristics in applying our methodology to unique panel data on consumption debt and intrahousehold gift exchanges we address a number of shortcomings in previous tests of theories of consumption behavior yet we find no evidence against the hypothesis that households smooth idiosyncratic fluctuations in their income our approach also uncovers several interesting features of rural credit and insurance markets

imperfect information and the theory of government intervention in farm credit markets this paper describes some possible economic motivations for government intervention in farm credit markets these motivations are made possible by explicit departures from the perfect information and complete market assumptions that underlie both the neoclassical competitive paradigm and the fundamental theorems of welfare economics to be more precise the analysis focuses on three types of asymmetric information between farmers and prospective outside investors both of whom are assumed to be risk neutral arguably the three informational asymmetries examined here represent natural departures from perfect markets in that unlike the unencumbered neoclassical model each elicits farmers optimal use of debt contracts rather than equity instruments or other contractual forms to raise investment capital despite their consistency with observed contractual choices all three of the models analyzed below yield free market equilibria that diverge from first best perfect information outcomes given the inefficiency of these market equilibria the key question raised and discussed here is can government improve upon the derived competitive outcomes and if so how despite the enormity of the credit rationing literature only a few extant studies address this question in models that are consistent with debt contracts among them are demeza and webb 1987 1988 1989 and innes 1988 which focus on the third type of informational asymmetry considered below the other two information structures posited in this paper have been studied in several analyses of credit markets but with attention focused on positive attributes of the unfettered competitive equilibrium rather than on prospective implications for welfare enhancing government intervention in what follows th s literature is surveyed and for the first two information structures some new policy results a e presented a critical discussion of the paper s limitations concludes the article

investment crowding out firm level evidence from northern germany michalek j ciaian p and kancs d a investment crowding out firm level evidence from northern germany regional studies the main objective of this paper is to estimate the extent to which firm investment is substituted crowded out by investment support policies granted under the european union rural development programme rdp the empirical analyses employed the difference in difference propensity score matching approach which allows several important sources of bias to be addressed such as selection bias simultaneity bias and functional form misspecification from which many previous studies suffer using panel data of 1333 firms from the schleswig holstein region in germany it is found that the crowding out effect of the rdp is close to 100 implying that firms use public support to substitute for private investments furthermore no evidence was found that due to the rdp programme support firms would have brought forward their investments planned originally for a later period rejecting t

spatial allocation and the shadow pricing of product characteristics abstract the paper considers an industry transforming primary commodities farm products into processed commodities food products it focuses on the allocation of embedded characteristics carbohydrate protein etc both across space and among commodities the approach generates a spatial competitive market equilibrium of production consumption transformation and trade for both primary and processed commodities along with the spatial distribution of shadow prices for the product characteristics the model provides a basis for analyzing the allocation and pricing of agricultural products food products and characteristics in spatial markets the empirical usefulness of the model is illustrated in the context of regional resource allocation in the u s dairy sector

does capital market structure affect farm investment a comparison using french and british farm level panel data this article considers whether differences in the structure of agriculture credit markets in france and the united kingdom alters the investment sensitivity to financial variables particularly cash flow using two panel datasets of french and british farms three approaches are used to test the sensitivity of investment to internal finance an inventory investment model a fundamental q model and euler equations for machinery investment the results suggest that the contrasting capital markets structures do induce differences in overall investment sensitivity to cash flow and its pattern across both farms with varying levels of collateral and between inventory and machinery investment this article explores whether differences in the structure of agricultural credit markets in france and the united kingdom affects access to credit theoretically asymmetric information in capital markets means that banks base their lending decisions on factors such as available collateral rather than projected profitability stiglitz and weiss binks and ennew hubbard if such information costs are affected by market structure the organization of the market also becomes a potentially important factor historical differences in the structure of agricultural capital markets in developed countries have long been recognized oecd in particular in many countries specific agricultural credit institutions for example farmer cooperative banks appeared in the first half of the twentieth century because of the difficulties faced by farmers in obtaining credit from commercial lenders the degree of state involvement in agricultural credit markets has also varied considerably across countries from

inflation and welfare in retail markets prior production and imperfectly directed search this paper considers the effect of monetary policy and inflation on retail markets goods are dated and produced prior to being retailed buyers direct their search on price and general quality buyers match specific tastes are private information sellers set the same price for all buyers some of whom do not value the good highly enough to buy it the market economy is typically inefficient as a social planner would have the good consumed under free entry of sellers the friedman rule is optimal policy when the upper bound on the number of participating sellers binds moderate levels of inflation can be welfare improving

the scramble in africa reorienting rural livelihoods abstract structural adjustment and market liberalization policies of the past 15 years have accelerated deagrarianization in sub saharan africa peasant producers have veered away from production of traditional export crops and commercial staple foods in rural areas remote from roads and urban markets nonagricultural income diversification has been substituted in the search for much needed cash earnings citing recent village survey evidence this paper argues that the economic restructuring of african smallholders work lives has been accompanied by deep rooted social change divisions of labor and decision making power within peasant households have altered and wealth differentiation between households has deepened depeasantization of the countryside is currently taking place as rural household members of both genders scramble for viable livelihoods

premature deagriculturalisation land inequality and rural dependency in limpopo province south africa cross national regressions reveal abnormally low agricultural workforce shares given gnp in developing countries that had historically concentrated land into large capital intensive farms we argue that such deagriculturalisation was premature since its concomitant labour shedding has undesirable outcomes in a new south african survey a large proportion of rural households and working age persons was dependent relying for income almost wholly on either migrant remittances or pensions a separate group with less poverty and unemployment relied mainly on local including own farm income the group was heavily over represented in one of the three regions where many more households had significant land

credit frictions and participation in over the counter markets abstract this paper formalizes a nash bargaining game between two players constrained by capacity decisions made prior to entering the negotiation in equilibrium strategic interactions drive capacity choices to zero and shut trade down despite the existence of gains from trade the game is embedded in a general equilibrium model of decentralized asset trade with credit frictions to investigate the interaction between availability of credit and investors participation modeled through their choices of inventory and payment capacity partial access to credit is sufficient to restore trade the strategic interactions between payment capacity and inventory generate endogenous heterogeneity in holdings trade sizes and prices and complementarity between money and credit

causal pathways of the productive impacts of cash transfers experimental evidence from lesotho abstract this paper has the double aim to study whether unconditional cash transfers have an impact on farm production and to look into the causal mechanisms through which government transfers produce productive impacts we use mediation analysis to identify the total effect of transfers on farm production and to isolate the influence of the labour channel from other transmission channels in particular we analyze whether changes in farm production are caused by transfer induced changes in the use of farm labour either by reallocating family labour between off and on farm work or by changes in the demand for hired labour or if other transmission channels are at work we find that cash transfers have a sizable impact on farm production but they do not lead to increased use of family or hired labour on the farm which implies that the productive impacts of cash transfers flow through other channels different from the labour one

money in search equilibrium in competitive equilibrium and in competitive search equilibrium we compare three market structures for monetary economies bargaining search equilibrium price taking competitive equilibrium and price posting competitive search equilibrium we also extend work on the microfoundations of money by allowing a general matching technology and entry we study how equilibrium and the effects of policy depend on market structure under bargaining trade and entry are both inefficient and inflation implies first order welfare losses under price taking the friedman rule solves the first inefficiency but not the second and inflation may actually improve welfare under posting the friedman rule yields the first best and inflation implies second order welfare losses

internal net worth and the investment process an application to u s agriculture recent models of firm investment decisions stressing informational imperfections in capital markets provide a foundation for interpreting evidence that movements in internal finance can predict investment spending even after one controls for measures of firms investment opportunities while such evidence is suggestive it is often open to other interpretations we examine these models using data on equipment investment in the u s agricultural sector this sector is particularly interesting because it has experienced large fluctuations in net worth and the profitability of investment and reasonable measures of net worth can be constructed our findings provide support for a class of internal funds models of investment under asymmetric information

changing time attitudes in intertemporal analysis intertemporal analysis is extended by generalizing the time weight function of an investor s utility function to account for changes in time attitudes the resulting measures of decreasing constant and increasing time attitudes are comparable to the arrow pratt measures of risk attitudes they help to enrich intertemporal theory provide meaningful hypotheses for testing and broaden the scope for decision analysis over time effects of the time attitude measures are illustrated in a model of an agricultural firm

scale characterizations in a dea directional technology distance function framework abstract the present study extends prior research on data envelopment analysis dea based returns to scale in view of the fact that the standard methods are very restrictive the extension is made in the context of the directional technology distance function that generalizes the shephard input and output distance functions the two main results in this extended setting are as follows first we show how banker s most productive scale size mpss concept is characterized second we obtain scale elasticity measures and examine the properties and the relationships with standard scale elasticity measures

empirical measurement of credit rationing in agriculture a methodological survey empirical analysis of rural credit market failure has been of key scientific and political interest in recent years the aim of this article is to give an overview of the various methods for measuring credit rationing that are employed in the literature furthermore the methods are subjected to a comparative evaluation of their specific strengths or shortcomings six approaches are distinguished measurement of loan transaction costs analysis of qualitative information collected in interviews analysis of quantitative information collected in interviews using the credit limit concept analysis of spill over effects with regard to secondary credit sources econometric household modeling and the econometric analysis of dynamic investment decisions an explicit comparison with a first best solution is impossible in the first three approaches since they essentially rely on a subjective assessment of borrowers access to credit based on qualitative or quantitative indicators the fifth and sixth approaches allow a rigorous interpretation in the framework of neoclassical equilibrium theory the fourth approach takes an intermediate position since spill over on segmented loan markets reveals a willingness to pay with regard to the supposedly less expensive but rationed primary source the approaches are fairly data demanding in general usually requiring specific data on loan transactions even so most approaches are applicable to cross sectional household data with the exception of the first all methods surveyed might plausibly be used to empirically detect credit rationing

short and long run credit constraints in french agriculture a directional distance function framework using expenditure constrained profit functions this empirical application investigates the eventual presence of credit constraints using a panel of french farmers the credit constrained profit maximization model proposed by fare grosskopf and lee is extended in three ways first we rephrase the model in terms of directional distance functions to allow duality with the profit function second we model credit constraints in the short run and investment constraints in the long run using short and long run profit functions third we lag the expenditure constraint one year to account for the separation between planning and production we find empirical evidence of credit and investment constraints financially unconstrained farmers are larger perform better and seem to benefit from a virtuous circle where access to financial markets allows better productive choices

an analysis of production efficiency differentials in the philippines in the late seventies and early eighties policy makers in many developing encouraged extensive research to develop appropriate rice technology for unfavourable rainfed environments the question addressed in this paper is whether the farmers producing under the non irrigated rainfed environments are achieving the potential of the technology fully at the farm level the empirical analysis which concerns the farm level production behaviour of rainfed rice farmers in the philippines indicates a wide variation in production efficiencies extension advice and credit availability appear to be the two major factors influencing the gap between farmers actual and potential production levels

farm debt default and foreclosure an economic rationale for policy action economic analysis of farm programs typically focusses on economic costs here we show that because of market failures and imperfections there are possible economic benefits to be derived from programs which reduce or eliminate the threat of default and foreclosure a production model of an indebted firm is developed and serves as a basis for an aggregate model which identifies possible costs and benefits from a program of transfers to indebted farmers the challenge facing policy makers is to design programs which capture the benefits of reducing the probability of default while minimizing perverse incentive effects of such programs

credit constraints their existence determinants and implications for u s farm and nonfarm sole proprietorships the objective of this study is to determine the effect of credit constraints on production for farm and nonfarm sole proprietorships a propensity score matching estimator is employed to provide unbiased estimates of the production impacts of being denied credit the empirical results demonstrate that the value of production is significantly lower for credit constrained sole proprietorships if this drop in the value of production is aggregated to a national level it constitutes only 3 and 13 of total value of production for farm and nonfarm sole proprietorships respectively copyright 2009 oxford university press

analyzing components of productivity growth using the bennet lowe indicator an application to welsh sheep farms this article introduces the bennet lowe total factor productivity tfp indicator the proposed measure is difference based additively complete and transitive we also develop a general nonparametric framework to exhaustively decompose all bennet type tfp indicators including the one introduced here into technical change technical efficiency change scale efficiency change and mix efficiency change this decomposition provides a powerful tool for policy makers to guide financial decisions on research and development extension subsidies and price support the empirical application focuses on the welsh sheep sector for the years 2001 2014 the results show that in this 14 year period welsh sheep farms increased their tfp by 30 28 on average 2 33 p a however the exhaustive decomposition shows that tfp growth is not distributed equally across all farms with an increasing divergence between front runners and laggards the negative values of scale efficiency change and mix efficiency change cast doubt on the current subsidy policies

on the timing of production decisions in monetary economies in most macroeconomic models inflation tends to be harmful in this paper we show that by simply changing the timing of production decisions by firms from on demand to in advance some inflation can boost welfare as long as goods are sufficiently perishable the main conclusion from this research is that by effectively hiding the strategic interaction between supply and demand assuming production on demand is not without loss of generality

explicit lagrange multiplier for firms facing a debt ceiling constraint abstract this paper provides the explicit expression of investment facing a binding debt ceiling and the explicit expression of the lagrange multipliers related to the binding debt ceiling constraint this result allows us to check for misspecification of the parameterizations of these lagrange multipliers used in euler investment equations tests during the 1990 s

energy abatement in chinese industry cost evaluation of regulation strategies and allocation alternatives abstract for chinese industry the costs of different energy consumption abatement scenarios are evaluated by the method of directional distance function these scenarios are based on the combinations of regulation strategies and allocation alternatives the former are sectors and provinces and the latter include the five principles of average intensity share absolute share discriminatory absolute and discriminatory intensity for all the scenarios the quantitative impacts in terms of output potential loss are calculated and compared due to less output potential loss for all the allocation alternatives the sector regulation strategy is shown to be more effective than the province regulation strategy it is also demonstrated that among all the scenarios considered the sector regulation based on the intensity share principle and the province regulation based on the absolute share principle are the two optimal the performances of energy abatement allocation of the 11th and 12th five year plans of china are assessed against the simulated scenarios

fundamental q cash flow and investment evidence from farm panel data this study used a 1976 1992 panel data set to test whether farm machinery investors face finance constraints tests were based on fundamental q investment equations in which cash flow was added as an additional explanatory variable results indicated that 1 credit constraints were generally not a problem during the 1970s boom 2 credit constraints became a problem during the 1980s and early 1990s because of tighter credit and or more conservative financial managerial styles 3 the investment cash flow relationships of low debt and older operator farms were not significantly affected by farm business cycles and 4 the investment cash flow relationships of high debt and young operator farms were affected strongly by business cycles debt level was the strongest determinant of credit constraints asset size and operator age were less important

expenditure constraints and profit maximization in u s agriculture the u s agricultural sector is undergoing some of its most severe financial problems since the great depression numerous reports have emerged of large numbers of farmers being unable to obtain short term oper

success in maximizing profits and reasons for profit deviation on dairy farms the weak axiom of profit maximization wapm was used to test how successful each of 70 individual new york state dairy farms was in maximizing profits using nine years of data the netput vectors were corrected for technological change using nonparametric indices that do not require the assumption of profit maximization nor any functional form for the underlying technology these technology indices are consistent with the nonparametric assumptions used in the wapm tests the average negative wapm deviation over the 70 farms was 0 20 indicating that on average these farms could have selected available netput vectors that would have increased profits by 20 of total receipts a tobit regression showed that the available characteristics on these farms explained very little of the variability in their abilities to select the best netput vectors yet increased age and additional education increased the ability to select the best netput vector

too much investment a problem of asymmetric information this paper shows that under plausible assumptions the inability of lenders to discover all of the relevant characteristics of borrowers results in investment in excess of the socially efficient level raising the rate of interest above the free market level will restore optimality this conflicts with generally held views and is contrasted with the stiglitz weiss model it is shown that the assumptions which yield overinvestment support debt as the equilibrium method of finance however under the stiglitz weiss assumptions used to derive an underinvestment result equity is shown to be the equilibrium method of finance

jobs and agricultural policy impact of the common agricultural policy on eu agricultural employment abstract this paper investigates the relationship between eu agricultural subsidies and the outflow of labor from agriculture we use more representative subsidy indicators and a wider coverage panel data from 210 eu regions over the period 2004 2014 than has been used before the data allow to better correct for sample selection bias than previous empirical studies we find that on average cap subsidies reduce the outflow of labor from agriculture but the effect is almost entirely due to decoupled pillar i payments coupled pillar i payments have no impact on reducing labor outflow from agriculture i e on preserving jobs in agriculture the impact of pillar ii is mixed our estimates predict that an increase of 10 percent of the cap budget would prevent an extra 16 000 people from leaving the eu agriculture sector each year a 10 percent decoupling would save 13 000 agricultural jobs each year however the budgetary costs are large the estimated cost is more than 300 000 per year or more than 25 000 per month per job saved in agriculture

non parametric efficiency progress and regress measures for panel data methodological aspects this purely methodological paper deals with the role of time in non parametric efficiency analysis using both fdh and dea technologies it first shows how each observation in a panel can be characterized in efficiency terms vis a vis three different kinds of frontiers i contemporaneous ii sequential and iii intertemporal these are then compared with window analysis next frontier shifts outward and inward interpreted as progress or regress are considered for the two kinds of technologies and computational methods are described in detail for evaluating such shifts in either case these are also contrasted with what is measured by the malmquist productivity index finally an alternative way of identifying progress and regress independent of the frontier notion and referring instead to some benchmark notion is extended here to panel data

a nonparametric approach to expenditure constrained profit maximization a nonparametric approach to expenditure constrained profit maximization is developed a deterministic frontier profit function is constructed with and without expenditure constraints foregone profit is used as dual evidence for the existence of expenditure constraints individual evaluations on performance and expenditure constraints are produced empirical analysis is based on survey data for california rice farms seventeen of the eighty two surveyed farms experience profit loss as a result of expenditure constraints

risk credit constraints and financial efficiency in peruvian agriculture abstract based on a panel data set we use a two stage analysis to evaluate the effects of access to formal credit on financial efficiency of farms in northern peru the first stage uses non parametric data envelope analysis to estimate farm specific measures of financial efficiency 28 per cent of farmers are financially inefficient and credit constraints reduce profits of these farmers by an average of between 17 and 27 per cent the second stage uses tobit regression to evaluate the determinants of financial inefficiency the results point to uninsured risk as a key determinant of financial inefficiency and suggest that policies to strengthen agricultural insurance markets would likely pay large dividends in rural peru

commitment advertising and efficiency of two sided investment in competitive search equilibrium abstract competitive search entails both commitment to and advertising of pay off relevant aspects of market participants this paper considers incrementally the implications of each in a labor market where both workers and firms invest prior to market entry a wide range of institutional arrangements are addressed within the same general framework when the characteristics of jobs or workers are advertised the efficient outcome pertains commitment without advertising typically leads to market unravelling the diamond paradox but whenever wages and human capital are advertised firms become residual claimants the private and social returns to investment coincide absent wage commitment the hosios condition implies efficiency when investments are advertised

inventory accumulation in a search based monetary economy abstract this paper explores the implications of a search based model of money for the linkage between steady state inventory accumulation inflation and welfare because individual traders in the search economy do not internalize the positive effects inventory accumulation and search effort have on the aggregate economy they are too low relative to social efficiency it is established that a tax on money balances can alleviate these externalities and improve aggregate welfare it does so by i directly increasing the optimal search intensity choices of the individual trader and ii stimulating the accumulation of inventories through a mundeil tobin type effect an increase in the equilibrium level of inventory accumulation also positively affects search effort the implications for optimal monetary policy are discussed

impact of liquidity risk on variations in efficiency and productivity a panel gamma simulated maximum likelihood estimation abstract the objective of this study is to assess the importance of short and long run liquidity or debt risk on technical inefficiency and productivity an alternative panel estimator of normal gamma stochastic frontier model is proposed using a simulated maximum likelihood estimation technique empirical estimates indicate a difference in the parameter coefficients of gamma stochastic production function and heterogeneity function variables between the pooled and the swamy arora panel models the results from this study show short and long run risk or variations in liquidity or debt servicing ratio play an important role in explaining the variance in efficiency and productivity

cap reform modelling supply response subject to the land set aside abstract this paper uses duality theory to develop a model of european community agriculture the model is used to investigate the impact of the land set aside provision of the recent package of reforms of the common agricultural policy we assume that producers chose output and variable input levels that maximize difference between revenue and variable cost by including first order conditions for the allocation of land across its uses we impose that the observed allocations are profit maximizing allocations to overcome the problem of incorporating many outputs into an estimable production structure we imposed a priori the restriction that the technology was weakly separable in major categories of outputs with this restriction it was possible to model production decisions in stages using consistent aggregates in the latter stages

frontier production functions and technical efficiency a survey of empirical applications in agricultural economics abstract the modelling and estimation of frontier production functions has been an important area of econometric research during the last two decades forsund lovell and schmidt 1980 and schmidt 1986 present reviews of the concepts and models involved and cite some of the empirical applications which had appeared to their respective times of publication this paper seeks to update the econometric modelling of frontier production functions associated with the estimation of technical efficiency of individual firms a survey of empirical applications in agricultural economics is an important part of the paper

farm consumption behavior in the presence of uncertainty and restrictions on credit farm consumption behavior has an important indirect role in determining the ability of farms to invest and grow in this paper i examine the effect on farm consumption behavior of the presence of quantitative restrictions on farm borrowing using a form of the life cycle model which allows for both consumption and production by the household the effect of borrowing restrictions on consumption behavior is tested econometrically for a sample of dutch farm households the results suggest that the life cycle model without borrowing restrictions is rejected by the data

credit market imperfections and the distribution of policy rents this article shows that credit market imperfections have important implications for the distribution of policy rents in a model with land as fixed factor and credit market imperfections when an area payment is given land rents go up by more than the subsidy on aggregate farms may lose from the subsidy the results depend on the extent to which subsidies have direct and indirect effects on the credit constraints on whether farms rent or own land and on farm heterogeneity

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

capturing the least costly way of reducing pollution a shadow price approach abstract the production analysis literature is increasingly concerned with estimating marginal abatement costs yet most studies do not emphasize the ways in which pollutants may be reduced and their costs which makes them unable to identify the least costly compliance strategy this paper utilizes the materials balance principle to relate pollution to the employment of material inputs a production model which allows input and output substitution downscaling of operations pollution control and emission permits purchases as compliance strategies is proposed and the implications of joint and non joint pollution controls for the trade off between pollutants and desirable outputs are considered marginal abatement costs reflecting the least costly way of compliance are derived by exploiting the duality between the directional distance function and the profit function

do futures benefit farmers simulations are used to analyze welfare and market and farm level effects of making futures available to producers of a storable commodity key features of the model are the explicit consideration of dynamic impacts due to inventories and of aggregate market effects associated with futures adoption by some producers application to the natural rubber market shows that futures availability can lead to sizeable market and farm level effects futures availability enhances consumer welfare reduces non adopter welfare and yields important welfare gains for adopters when their market share is small and welfare losses when they account for a sufficiently large market share

developments in biophysical and bioeconomic simulation of agricultural systems a review this paper reviews the features and uses of some recent biophysical and bioeconomic simulation models in agricultural economics research problems associated with earlier models are discussed and the extent to which recent simulators have addressed these concerns is appraised some salient factors that will enhance the continued relevance of simulators as research and decision support tools are indicated
