the economic consequences of reduced fertilizer use a virtual pricing approach the virtual pricing approach is applied to perform an ex ante analysis of reduced chemical use on agricultural output input demand and profitability aggregate data on indiana agriculture spanning the 1950 86 period are used to estimate parameters of a normalized quadratic profit function using bayesian techiques empirical results on the response of substitute and complementary inputs to a 15 and a 30 fertilizer restriction are obtained and the ad valorem taxes required to accomplish such restriction are calculated

the litigious plaintiff hypothesis case selection and resolution the process through which cases are selected for litigation cannot be ignored because it yields a set of lawsuits and plaintiffs that is far from a random selection either of potential claims or of potential claimants we present a theoretical framework for understanding the operation of this suit selection process and its relationship to the underlying distribution of potential claims and claimants the model has implications for the trial rate and the plaintiff win rate at trial our empirical analysis using data on over 200 000 federal civil litigations yields results that are strongly consistent with the theory

pretrial bargaining with self serving bias and asymmetric information abstract we introduce self serving bias into the bebchuk rand journal of economics 15 1984 404 model in which trials result from asymmetric information and characterize the equilibrium an increase in the self serving bias of a defendant who receives an offer can under some circumstances reduce the incidence of trial more typically however we find that an increase in the self serving bias of either player increases the incidence of trial an increase in the self serving bias of a player who receives the offer has ambiguous effects on that player s welfare self serving bias serves as a commitment mechanism not to accept offers which are too unfavorable but players with such a bias typically end up in trial more often for the player making the offer we find that an increase in self serving bias unambiguously lowers welfare

testing for non jointness in oil and gas exploration a variable profit function approach although the assumption of non joint production is made in a number of areas of economics its empirical validity is seldom examined in this paper we investigate the hypothesis of non jointness in the context of a multiple output production process which utilizes both fixed and variable inputs specifically we test the hypothesis of almost non jointness in the input quantities and prices as well as the hypothesis that inputs and outputs are separable using data on oil and natural gas exploration in alberta canada to facilitate global tests of these hypotheses we estimate a generalized linear generalized leontief variable profit function both with and without the restrictions implied by nonjointness and by separability on the basis of likelihood ratio tests we reject the hypothesis of separability but are unable to reject the non jointness hypothesis based on the maximum likelihood estimates obtained in the non joint case we examine some empirical issues concerning oil and gas exploration activity

dynamic corn supply functions a model with explicit optimization both static and dynamic models have been used to estimate aggregate supply elasticities for annual crops the early studies relied on static singleequation models in a few variables assumed static price expectations e g kohls and paarlberg and produced very small estimates of own price supply elasticities e g 0 07 for corn nerlove 1956 1958a and nerlove and addison showed that agricultural supply models incorporating adaptive price expectations and or dynamic resource adjustment produced larger estimates of supply elasticities for corn and other agricultural commodities additionally they showed that supply elasticities obtained from static models need not be bounded by the short run and long run supply elasticities of

agricultural competitiveness the case of the united states and major eu countries abstract growth in the agricultural gdp of four major european countries is compared with us agricultural growth for the period 1974 1993 the agricultural sector s relative prices are taken into account along with economy wide factor market adjustments for denmark france germany and the uk the effects of declining real prices and changes in input levels on growth in agricultural gdp are relatively small total factor productivity tfp growth appears to be the major contributor to european agricultural gdp growth in comparison tfp is the major source of growth in us agricultural gdp but its rate of growth is lower than the european countries in contrast the declining real prices for us agriculture had a relatively large effect on its gdp however in recent years the effects of declining real prices and declining rates of growth in tfp on european agriculture are relatively large in the longer run the relative competitiveness of us agriculture is largely dependent on its ability to sustain and increase growth in tfp

profit function approximations and duality applications to agriculture monte carlo simulations of profit functions indicate that flexible functional forms may be ranked nearly the same with respect to allen uzawa partial substitution elasticities or price and fixed factor elasticities flexible functional form approximations of output price elasticities are generally worse than approximations of input price or fixed factor elasticities minflex laurent functional forms did not appear to approximate underlying elasticities any better than did their translog and generalized leontief counterparts

estimating the price elasticity of demand for family and hired farm labour in england and wales the agricultural workforce in the uk has been declining since the middle of the last century however the different types of agricultural labour have been variously affected and hence the composition of the agricultural workforce has been undergoing continuous change these changes in the structure of the agricultural workforce have serious implications not only for the policy makers but also for farm workers and farm businesses and those that service their needs the study compares and explores the own price elasticity of demand for two groups of agricultural labour that of family and hired to enable the effects of agricultural policy on the structure of the agricultural workforce in both the short and long run to be estimated this was done using two different methodologies single equation and duality based system models the similarities in the resulting elasticities give confidence in the estimates these estimates can be used to help forecast the future structure of the agricultural workforce

pretrial bargaining with asymmetric information unilateral versus bilateral payoff relevance author affiliation amy farmer amyf walton uark edupaul pecorino ppecorin cba ua edu acknowledgment we would like to thank akram temimi and two anonymous referees for providing helpful comments on the article 1 introductionasymmetric information is a leading explanation for bargaining failure and the role of asymmetric information has been extensively analyzed in the civil litigation literature 1 most of this literature concerns information that has bilateral payoff relevance in the sense that the information in question affects the expected payoff at trial of both the plaintiff and defendant when there is bilateral payoff relevance trials may be predicted in the equilibrium of the bargaining game regardless of whether the informed or uninformed party makes the offer in this article we analyze information that has unilateral payoff relevance meaning that it affects the expected payoff of one of the two parties to the dispute but not the other as an example suppose the plaintiff has private information on her risk preferences this affects her expected payoff at trial but not the defendant s when there is unilateral payoff relevance there are never inefficient trials in the equilibrium of the game where the informed party makes the offer 2 however there may still be costly disputes in the equilibrium of the game in which the uninformed party makes the offer examples of information with bilateral payoff relevance include information on the probability that the plaintiff will prevail at trial and information on the amount of the judgment to be awarded at trial in the event the plaintiff is victorious in both cases the information clearly affects the expected payoff of both the plaintiff and defendant at trial and these are the types of informational asymmetry considered most often in the literature what type of information has only unilateral payoff relevance one example mentioned above is information on risk preferences farmer and pecorino 1994 swanson and mason 1998 and heyes rickman and tzavara 2004 all examine asymmetric information on risk preferences within the context of the screening model in which the uninformed party makes the offer 3 in each case trials are predicted in the equilibrium of these models as long as trials are not too costly for the participants however other types of information also have only unilateral payoff relevance a large literature on the ultimatum game has provided convincing evidence that under certain circumstances individuals will express a preference for being treated fairly 4 this preference may be expressed specifically by the percentage of her own court costs a player is willing to concede to her opponent via his settlement offer 5 since this preference is not observable and presumably differs across individuals the proposer in a screening game must decide how much of the joint surplus of settlement he will attempt to extract without knowledge of how low he can go before triggering a rejection suppose the judgment is 100 000 and the plaintiff s court costs are 30 000 a plaintiff without a taste for fairness will accept an offer of 70 000 rather than proceed to trial a plaintiff with a taste for fairness might as an example accept no less than 90 000 the defendant then must choose between an offer of 90 000 and 70 000 without knowledge of whether the other party has a taste for fairness or not the defendant will make the low offer if he believes it will be accepted with a sufficiently high probability if the plaintiff does indeed have a taste for fairness she will reject the low offer and a trial will result presumably a mechanism along these lines explains the persistence of disputes in ultimatum game experiments another example of information with unilateral payoff relevance is the degree of litigiousness which can be modeled as differences in perceived court costs on the part of the plaintiff eisenberg and farber 1997

acreage decisions under risk the case of corn and soybeans an acreage supply response model is developed under expected utility maximization the resulting framework is used to specify and estimate a system of risk responsive acreage equations for corn and soybeans in the united states particular attention is given to the truncation effects of government price supports on the distribution of corn and soybean prices also a wealth variable is included in the acreage equations the empirical results indicate that risk and wealth variables play an important role in cornsoybean acreage decisions the analysis also shows that cross commodity risk reduction is important in acreage allocation decisions

market based systems for reducing chemical use in agriculture in the united states this study uses a computable general equilibrium cge model of the u s economy to estimate the economic effects of agricultural fertilizer and pesticide input reductions on individual farm sectors and on the economy as a whole the costs of reducing agricultural chemicals using a market based approach and a command and control approach are compared the real cost to society of restrictng fertilizer and pesticide use by 20 percent across all uses is estimated to be 2 3 billion a market based approach that would provide incentives to reduce chemical use in the most cost efficient manner would be about 10 percent less costly

supply and demand functions for multiproduct u s cash grain farms biases caused by research and other policies this study presents new estimates of supply and demand elasticities for u s multiproduct cash grain farms and estimates of input and output bias effects caused by public and private crop research extension and farmers schooling the study also shows that the social rate of return to public crop research is large about 62 percent

endogenous regional agricultural production technologies technical relationships between six productive factors for ten agricultural produvction regions in the continental united states are examined the applied methodology provides a departure from conventional production methodologies contained in the literature by allowing aggregate technical relationships to be endogenized within the economic system

measurement of total factor productivity growth and biases in technological change in western australian agriculture this study investigates productivity growth in broad acre agriculture in western australia tornqvist indices of three output groups crops sheep products and other and five input groups livestock materials and services labour capital and land are constructed and discussed indices of total output and total inputs are also derived and used to form an index of total factor productivity that is observed to grow at an average annual rage of 2 7 the input and output indices are also used in the estimation of output supply and input demand equations derived from a flexible profit function the generalized mcfadden functional form is used because it is possible to impose global curvature upon it without loss of flexibility asymptotic chi square tests reject the hypotheses of hicks neutral technical change in inputs and in outputs technical change is observed to be materials and services saving relative to the other input groups and also appears to favour wool and sheepmeat production relative to the other output groups

the intercountry agricultural production function another view factor productivity in agriculture is estimated from repeated observations on a sample of fifty eight countries under the assumption that all countries have access to the same technology technology is viewed as a collection of techniques each technique is represented by a production function the choice of the implemented techniques is determined by the state variables which represent the physical and economic environment within which the firms operate the statistical model is that of varying coefficients and it is estimated by a method which utilizes principal components and multiple comparisons

united states demand for coffee imports abstract the united states one of the world s largest coffee importers imports coffee beans from a variety of different countries these countries are aggregated into five groups representing five broadly defined types of coffee imports of the five coffees over time are examined to determine price expenditure and substitution elasticities these elasticities reflect preferences as well a technical relationships in the form of blending recipes the lower the degree of substitutability between the different types of coffee the more inelastic the demand from the united states facing groups of exporting countries the results suggest rigidities in united states imports of coffee of different types these rigidities are evidenced by substantial complementarity among the five coffee types preference patterns are very similar across a wide range of model specifications there are differences in expenditure elasticities for different types of coffee in the united states

supply demand and technology in a multiproduct industry texas field crops the purpose of this paper is to examine the structure of agricultural production for six texas field crops cotton grain sorghum wheat corn rice and hay which account for nearly 95 of recent field crop value specific objectives are to a test the structure of technology to determine i if output and input utilization choices for individual products are independent of production decisions about other outputs and ii if products and or inputs can be consistently aggregated b estimate a coherent set of interrelated supply functions for the six commodities and input demand functions for fertilizer and hired labor because the empirical focus of this paper is specific to one state the results will be of limited value for interpreting specific production relationships elsewhere however the problem is of common interest in production agriculture and the techniques used demonstrate an important application of dual modeling

the effects of suburbanization on agriculture this article conceptualizes the effects of suburban population density and land speculation on agricultural production choices prices and profits a dual profit function model and a system of reduced form price equations are used to estimate these effects for new jersey results show that vegetable production is the only subsector to benefit from suburbanization while livestock is the most adversely affected suburbanization reduces responsiveness to agricultural prices and discourages capital and land use the overall impact on profits is positive when capital gains on land are included policy implications for farmland preservation and right to farm legislation are discussed

the demand for canadian fats and oils a case study of advertising effectiveness the fats and oils market in canada is characterized by generic butter and brand margarine shortening vegetable oils advertising in this study the economic interrelationships in the consumption of fats and oils are examined and the effectiveness of the advertising programs is evaluated the two stage demand model used is made up of a single equation determining canadian aggregate expenditure on fats and oils and an expenditure share system derived from a translog indirect utility function for each of four products butter margarine shortening and vegetable oils the demand for individual fats and oils is significantly affected by lagged advertising expenditure levels habit persistence and a time trend as well as the traditional variables of price and expenditure

short and long run returns to agricultural r d in south africa or will the real rate of return please stand up abstract this paper briefly presents the results of a total factor productivity tfp study of south african commercial agriculture for 1947 1997 and illustrates some potential pitfalls in rate of return to research ror calculations the lag between r d and tfp is analyzed and found to be only 9 years with a pronounced negative skew reflecting the adaptive focus of the south african system the two stage approach gives a massive ror of 170 the predetermined lag parameters are then used in modeling the knowledge stock to refine the estimates of the ror from short and long run dual profit functions in the short run with the capital inputs treated as fixed the ror is a more reasonable 44 in the long run with adjustment of the capital stocks it rises to 113 which would reflect the fact that new technology is embodied in the capital items however the long run model raises a new problem since capital stock adjustment takes 11 years 2 years longer than the lag between r d and tfp if this is assumed to be the correct lag the ror falls to 58 a best estimate the paper draws attention to the possible sensitivity of rate of return calculations to assumed lag structure particularly when the lag between changes in r d and tfp is skewed

research and productivity in mexican agriculture partial and total factor productivity tfp measures of mexican agriculture are calculated for 1960 90 the long run effects of research and international transfer of technology on tfp are examined over the 1940 90 period using cointegration procedures tfp increased at an average annual rate of 2 5 exceeding the corresponding growth in the united states 2 1 tfp grew particularly fast in the 1960s and 1970s a 1 rise in research investment increased tfp by 0 13 and a 1 increase in u s tfp translated into a 1 11 increase in mexican tfp the average annual rate of return to research investment is about 64

an analysis of u s aggregate output response by farm size abstract past empirical evidence on supply response by size of farm in the u s a provides no clear basis to conclude that supply elasticities vary systematically with farm size in this paper the central hypothesis that no systematic relationship exists between production response to price and size of farm is rejected u s farms are disaggregated into nine economic size categories and own price supply elasticities are measured for per farm and total agricultural output empirical results from this study suggest that supply response does vary systematically by farm size with smaller farms exhibiting greater elasticities than mid sized farms

the elasticity of scale and the shape of average costs different concepts of returns to scale the first which is most widely used for defining returns to scale is the relative increase in output as all input quantities are increased proportionally along a ray through the origin the second which is the more relevant concept for micro economic analysis is the increase in output relative to costs for variations along the expansion path where input prices are constant and costs are minimized at every output 2 as it turns out these two concepts yield equal measures for the elasticity of scale3 e at every minimum cost point in the input space however the change in e with output is generally different for the two concepts 4 since expansion paths do not coincide with rays unless the production function is homothetic 5 but it is the change of e along the expansion path and not along the raywhich determines the shape of the average cost curve ac and which is therefore relevant for the analysis of firms and industry behavior under competition 6 these relations are stated and analyzed below it is shown that assumptions made in the literature7 which are related to the behavior of e along rays or to the slope of the technically optimal surface where returns to scale are locally constant are irrelevantbeing neither necessary nor sufficient for implying classical u shaped average cost curves the following definitions and results are used here

commitment versus discretion in the peasant dictator game abstract we report an experiment designed to test the influence of commitment versus discretion in a simple bargaining game game theory predicts and the public policy literature emphasizes that the ability to make commitments promotes efficiency we find that commitment does significantly increase efficiency in the experiment finally we relate our findings to the extant literature on extensive form bargaining experiments by examining fairness and trust as explanations for some observed anomalies journal of economic literature classification numbers c720 c790 c920 e610

food price changes and household welfare what do we learn from two different approaches the use of a marginal approach can significantly distort the predicted effects of large price variations on monetary welfare over the medium to longer term this paper aims at shedding some light

sources of growth in french agriculture since the slowdown in the growth of world agricultural trade in 1980 the united states and the european community ec have engaged in a series of debates over their respective agricultural policies high producer prices and the general absence of production controls in europe have been of particular concern in the united states as world grain stocks have risen and the ec has emerged with substantial subsidies as a net cereals exporter levels of frustration have increased on both sides of the atlantic as the united states has responded with its own export enhancement payments and other costly policies with current positions difficult to sustain the united states and some members of the european community now seek means to limit their conflict and obtain relief from the high costs of their agricultural programs the reduction of grain stocks resulting from the drought affect

litigation and settlement under two sided incomplete information this paper deals with a simple game of litigation and settlement with incomplete information parties are assumed to have the choice between settling their dispute out of court or resorting to costly litigation the set of sequential equilibria is characterized and conditions are given under which an efficient equilibrium does exist efficient equilibria however will be ruled out by various tests of refinement a comparative statics analysis is carried out with respect to the quality of private information which parties are assumed to receive before any moves have to be made

estimating substitution and expansion effects using a profit function framework this study reports a first attempt to derive all the relevant information with respect to the structure of production of an industry using knowledge of only a profit function using estimates of a profit function for canadian agriculture a procedure to separate substitution and expansion effects for both inputs and outputs was implemented information concerning net input and output substitution and complementarity possibilities were obtained the most important empirical results suggest that the hypothesis of nonjoint production of crop and animal outputs in canadian agriculture cannot be rejected and that hired and operator labor are complements rather than substitutes

multiple input multiple output production choices and technology in the u s wheat region duality theory motivates a translog expected profit function consistent with multiple products price uncertainty preseason climate constraints acreage control policies and possibly nonhomothetic technology although multiple outputs are allowed enterprise specific data is not necessary instead time series measures of output revenues and expected prices input expenses and prices and fixed input flows are employed appropriate measures of elasticities of choice returns to size and biases in technological change are derived results indicated decreasing returns to size rather limited though complementary responsiveness of choices to price changes and the nature of biases in technological changes

modelling technical change in italian agriculture a latent variable approach this paper presents an alternative approach to the measurement of technical change it is based on the latent variable level of technology that enters explicitly the input demand system and on a hypothesis about the innovation generating process by adding measurement error equations the behavioral system can be viewed as a multiple indicators multiple causes mimic model the parameter estimates are obtained with a maximum likelihood estimator which involves the implicit covariance matrix the analysis refers to italian agriculture and the results provide some evidence on the nature and level of technical change during the years 1961 1991

estimating substitution and expansion effects comment in recent years there has been a proliferation of estimated supply and demand elasticities for the agricultural sector the combination of duality theory flexible functional forms and powerful computing resources have made it easy to estimate complete supply and demand systems with relatively few restrictions on the elasticities as a profession we must sort through these numerous estimates many of which are contradictory and identify the sensible ones a recent article by lopez in this journal illustrates this methodology this comment uses the lopez results to demonstrate how hitherto underutilized theoretical insights can be usefully employed in evaluating published elasticities the first issue involves the expected signs of off diagonal elasticities for uncompensated supplies and demands the analysis of which dates back to hicks work in 1939 he predicted that in the absence of significant fixities we should expect goods to be gross complements in production this concept has been further developed and refined the assumptions necessary to generate this normal case are reviewed in the second section then the relationship between gross and compensated elasticities is examined in both of these sections empirical results from the lopez article are found to contradict predicted outcomes based on economic theory and an attempt is made to analyze these discrepancies

production economics worthwhile investment abstract agricultural production economics research is examined within a broad framework of scientific development and utilization recent findings in selected areas of the subdiscipline are examined and opportunities for further fruitful inquiry are identified a few stylized facts emerge from recent work and suggest the need for much careful hypothesis testing model exploration and empirical sensitivity analysis in the future

the structure of u s agricultural technology 1910 78 this paper utilizes 1910 78 time series data and a single product aggregate translog profit function to measure the structure of u s agricultural technology duality relations are used to devise a multifactor measure of biased technical change a measure of nonhomotheticity is introduced which indicates the effects scale change has had on aggregate cost shares the empirical analysis finds that different nonhomothetic technologies characterized the prewar and postwar periods differing technical change biases are consistent with relative price trends during the two periods showing that the long run structure of u s agricultural technology has been consistent with the hayami ruttan induced innovation theory

anarchy in the laboratory and the role of the state abstract a recent literature on the economics of conflict provides conditions under which groups of individuals divide up between producers and predators an anarchic equilibrium as well as conditions under which a government agent is empowered to make collective action choices that can completely deter predation we test these theoretical predictions in a laboratory experiment in the absence of a government agent groups of subjects choose actions consistent with the anarchic equilibrium the introduction of a government agent charged with maximizing the consumption of producers enables subjects to achieve nearly perfect coordination on the pareto superior equilibrium where all individuals choose to be producers

agricultural production technologies with systematic and stochastic technical change a production system modeling tool is developed that implements recent work on autoregressive and endogenous stochastic production technologies associated with generalized fechner thurstone gft optimizing functions a gft class production system is used to evaluate the empirical support for technology specifications inherent in the neoclassical theoretic structure of an agricultural production region little likelihood support is found for zero serial correlation elimination of systematic technology changers from the production system strict neoclassical production technologies hicks neutral technical change or zero homogenous factor demand functions

long run profit functions for multiproduct firms a long run specification of the multiproduct profit function is developed from the restricted profit function the multiproduct restricted profit function and the envelope condition are used to estimate the optimal long run levels of the quasi fixed factor formulas for long run marshallian elasticities of substitution and transformation economies of scope product specific and overall economies of scale and economic measures of capacity utilization are developed for the translog functional form the methodology is illustrated by a case study of the new england otter trawl industry

transferable quotas enforcement costs and typical firms an empirical application to the norwegian trawler fleet an alternative to traditional regulations of fisheries to avoid rent dissipation is the use of individual transferable quotas itqs where prices in the quota market provide the necessary information to owners of harvest rights to contract with each other however even under such a decentralized regime information on the underlying technology of the fishing vessels is also necessary first since most fisheries consist of many interrelated production processes in order to avoid rent dissipation by discarding wrong output mix etc the structure of production in the multispecies fishery must be known to design a proper quota system second an itq system may create incentives for misreporting by understating the actual catch this may especially be the case where the expected degree of self enforcement is low the paper proposes a way to reduce the information requirements under regulation with asymmetric information by constructing a typical firm and comparing performance for the other vessels to this firm based on the typical firm and if the industry is relatively homogenous the performance and hence catch of any other firm in the industry can be predicted within a certain range further the paper applies this idea to the norwegian trawler fleet to assess the production structure in terms of jointness input output separability and the supply and demand elasticities for the fishing firms this information characterizes the fishery and thus how the quota system may be designed and how to construct a yardstick in order to reduce the enforcement cost under a decentralized regulation of itqs

testing for input substitution in a regulated fishery input restrictions are commonly used to prevent rent dissipation in fisheries this paper examines whether these schemes are successful by calculating the degree of input substitution between restricted and unrestricted inputs conventional elasticities of substitution cannot be used when the firm faces controls on the use of some inputs in this case the appropriate measure of substitution the elasticity of intensity must be used data from the british columbia salmon fishery provide evidence of input substitution possibilities for two vessel types these results call into question the usefulness of input control schemes

input demands and inefficiency in u s agriculture markov chain monte carlo mcmc methods are used to estimate a seemingly unrelated regression sur system of input demand functions for u s agriculture our demand functions have flexible forms and allow for nonrandom technical inefficiency concavity constraints are imposed at individual data points and the distributions of measures of relative technical efficiency are constrained to the unit interval results are evaluated in terms of characteristics of the posterior distributions of parameters measures of relative technical efficiency and other nonlinear functions of the parameters

efficiency subsidies and environmental adaptation of animal farming under cap the purpose of this article is to model the interaction between the targets of the current cap environmental adaptation subsidies and efficiency q1 of animal farming to this end we first have to identify the production frontier and relative efficiency level for each animal oriented farm in the sample the production frontier and efficiency index for each type of farm assuming no specific production functions are identified using data envelope analysis dea techniques we then address the relationship between relative efficiency farm size and environmentally friendly behavior by carrying out a nonparametric regression of efficiency on economic size a proxy for the degree of environmental appropriateness and regional dummies calculations of the efficiency of the farms including direct subsidies are compared with the counterfactual exercise in the case in which direct subsidies are not considered finally we look for relations between subsidies and factors such as farm size efficiency and environmentally friendly behavior one key result shows that on average direct payments generally tend to increase efficiency however in most of the cases the mean efficiency decreases as the percentage of direct payments rises direct payments are found to be positively related to environmentally friendly production at least in germany however in general the direct payment system is not sufficient to offset the fact that the less environmentally friendly farms as well as the larger farms are more efficient

dynamic input demand an application to agriculture a theoretically consistent analytical framework for examining dynamic agricultural input demand is developed and applied results from duality theory on restricted variable profit functions are incorporated into a long run dynamic optimization framework input use is affected by external adjustment costs which permits sluggish factor adjustment

demand for farm output in a complete system of demand functions demand interrelationships for farm outputs that are theoretically consistent with consumer demand and marketing group behavior provide important linkages between retail and farm prices a conceptual model based on reduced form specifications for retail and farm prices is formulated and applied empirically to a set of eight disaggregated food commodities this approach circumvents the need for retail quantities which are frequently unavailable for disaggregated food commodities the results are consistent with theory and generally indicate significant substitution between farm and marketing inputs except for poultry derived demand elasticities are at least 40 larger compared to those derived assuming fixed proportions

credible pretrial negotiation pretrial negotiation is a structured environment in which to study bargaining with incomplete information when a plaintiff believes that a defendant owes him damages he may first attempt to reach a private settlement before resorting to a costly court imposed judgment a central issue in their negotiations is whether the plaintiff s threat to litigate is credible it is possible for the plaintiff to undermine the credibility of his litigation threat by making a settlement demand that is insufficient as a result the plaintiff must raise his settlement demand to limit the amount of bad news he can learn if his offer is rejected when this credibility constraint is binding traditional comparative static results are reversed in addition even though the defendant is being sued he wants the plaintiff s threat to be credible

constrained output maximization and us agriculture this paper presents a framework for estimating an indirect production function and then applies it to aggregate us agriculture issues addressed include tests of standard hypotheses about the underlying technology homotheticity neutral technical change etc as well as examination of consistency in aggregation and the effects of changes in the level of aggregate expenditure on farm output since there already exist several studies empirically describing agricultural production technologies with indirect objective functions one might fairly ask whether this paper really breaks any new ground we feel that it does one reason is that existing studies e g binswanger 1974 lopez 1980 ball and chambers 1982 ray 1982 and weaver 1983 all rely on either profit or cost functions to date there appears to be only one study using an indirect production appelbaum 1979 and it is not in agriculture this seems unfortunate because there are many instances in agriculture for which an indirect productio

on the use and misuse of profit functions for measuring the price responsiveness of peasant farmers a comment the standard profit function approach has been applied successfully in a number of ldcs to measure the price responsiveness of peasant farmers yet various problems afflict this approach including but not restricted to the existence of non competitive market structures zero valued observations exclusion of relevant variables lack of participation in output and or input markets and endogeneity of input and or output prices the impact of these problems on estimation results however can be minimised through modifications and adaptations of the standard approach better specification of the underlying technology and the use of selected functional forms

the output bias of technological change in postwar japanese agriculture in order to explain the rapid change in the output mix this study tests the hypothesis that technological change in postwar japanese agriculture was biased towards livestock production a multioutput translog cost function was estimated for the 1958 84 period in which results are consistent with the hypothesis furthermore changes in the composition of crop and livestock production had significant impacts on relative factor uses above all expanding livestock production required relatively less labor than expanding crop production implying a positive contribution to the rapid exodus of labor to the nonagricultural sectors

social norms and trust among strangers we study the development of a social norm of trust and reciprocity among a group of strangers via the contagious strategy as defined in kandori 1992 over an infinite horizon the players anonymously and randomly meet each other and play a binary trust game in order to provide the investors with proper incentives to follow the contagious strategy there is a sufficient condition that requires that there exists an outside option for the investors moreover the investors payoff from the outside option must converge to the payoff from trust and reciprocity as the group size goes to infinity we show that this sufficient condition is also a necessary condition to sustain any sequential equilibrium in which the trustees adopt the contagious strategy our results imply that a contagious equilibrium only supports trust if trust contributes almost nothing to the investors payoffs
