distinguishing between whole farm vs partial farm participation in the conservation reserve program by distinguishing between the decision to participate in the conservation reserve program crp and the decision for whole farm vs part farm participation we model participation as separate binary decisions our results suggest the farm characteristics and other factors affect the decision to participate in crp differently than the decision regarding whole farm vs part farm participation this model formulation also helps to clarify the conditions under which the effect of crp payments on the acreage enrolled in the program is positive or negative

evolution of the economics of agricultural policy agricultural economists helped develop farm programs to respond to the dire economic situation of the 1920s and 1930s some early authors appreciated that such policies created problems in markets for commodities and inputs over time our understanding of agricultural issues and policies has deepened through the application of improved models and tools of analysis to more extensive data we have developed better answers to old questions and have responded to changing policy instruments market contexts and policy concerns this article traces the evolution of our deepening economic understanding of the causes and consequences of agricultural policy

is protection for sale evidence on the grossman helpman theory of endogenous protection grossman and helpman 1994 present a theory of endogenous protection by explicitly modeling government industry interactions for which mere black box models previously existed they obtain a ramsey pricing type solution to the provision of protection which emphasizes the role of inverse import penetration ratios and import elasticities on the lobbying side the model makes predictions about lobbying competition and lobbying spending according to deadweight costs from protection the model not only makes for richer theory in terms of rigor and elegance but its predictions are directly testable whether the grossman helman model stands up to real world data is investigated in this paper predictions from both the protection side and lobbying side are tested using cross sectional u s nontariff barrier data we also compare the second generation grossman helpman model with a more traditional specification our results call for serious consideration of this model in the political economy literature

combining risk assessment and economics in managing a sanitary phytosanitary risk the agreement on the application of sanitary and phytosanitary sps measures provides guidelines for countries to protect domestic production from pests and diseases the guidelines permit consideration of consumer welfare we find an optimal set of sps measures considering total welfare and mitigation strategies our model suggests that it is optimal and less restrictive to apply mitigation strategies first and then an additional smaller tariff if necessary relative cost of mitigation determines the amount of the mitigation strategies applied in the importing and exporting countries

disguised protectionism global trade rules and alien invasive species current international law strongly favors policies designed to make imports safer e g in terms of invasive species over policies explicitly designed to discourage imports we show that this preference may be counterproductive a externality in trade is incorporated into a political economy model of policy formation nations can address the externality by inspecting cargo and imposing a fine on contaminated imports we compare the equilibrium when inspection is the only policy option relative to the equilibrium that emerging when nations may also manipulate the tariff ruling out the tariff causes socially excessive stringency in general social welfare losses if domestic supply is highly inelastic and in some circumstances an increase in the real tariff measured as the difference between world and domestic prices

a time series analysis of representative agent models of consumption andleisure choice under uncertainty this paper investigates empirically a model of aggregate consumption and leisure decisions in which utility from goods and leisure is nontime separable the nonseparability of preferences accommodates intertemporal substitution or complementarity of leisure and thereby affects the comovements in aggregate compensation and hours worked these cross relations are examined empirically using postwar monthly u s data on quantities real wages and the real return on the one month treasury bill the estimated values of the parameters governing preferences differ significantly from the values assumed in several studies of real business models several possible explanations of these discrepancies are discussed

policy choice theory and evidence from commitment via international trade agreements abstract why do governments employ inefficient policies when more efficient ones are available for the same purpose we address this puzzle in the context of redistribution toward special interest groups sigs by focusing on a set of important policies tariffs and non tariff barriers ntbs in our policy choice model a government can gain by committing to constrain tariffs through international agreements even if this leads to the use of less efficient ntbs commitment has political value because it improves the bargaining position of a government that is weak relative to domestic sigs using detailed data we find support for several of the model s predictions including i tariff commitments in trade agreements increase the likelihood and restrictiveness of ntbs but not enough to offset the original tariff reductions ii tariff commitments are more likely to be adopted and more stringent when the government is weaker relative to a sig thus the results can explain the use of inefficient policies for redistribution and suggest that the bargaining motive is an important source of the political value of commitment in international agreements

input use decisions with greater information on crop conditions implications for insurance moral hazard and the environment emerging precision agriculture technologies allow farms to make input decisions with greater information on crop conditions this greater information occurs by providing improved predictions of crop yields using remote sensing and crop simulation models and by allowing farms to apply inputs within the growing season when some crop conditions are already realized we use a stylized model with uncertainty in yield and price to examine how greater information on crop conditions i e a forecast affects input use for insured and uninsured farms we show that moral hazard decreases farms apply more inputs as the forecast accuracy improves when the forecast indicates good yields and vice versa when the forecast indicates bad yields in the long run moral hazard decreases in response to an improvement in forecast accuracy even though moral hazard decreases in the long run indemnity payments are likely to increase in the long run driven by the increase in moral hazard when the forecast indicates bad crop conditions we use the results of our model to discuss the potential impact of different technologies and types of inputs on the federal crop insurance program and the environment

avoiding invasives trade related policies for controlling unintentional exotic species introductions abstract international commodity trade serves as the primary conduit for unintentional introductions of damaging exotic species we use a simple model of contaminated goods trade to analyze the optimal mix of tariffs and inspections as means of controlling damage from this negative externality among other policy relevant results we find that 1 while it is always optimal to employ tariffs there are non trivial cases in which inspections should optimally be set to zero 2 a higher infection rate requires a higher tariff but beyond a point optimal inspections decrease in the infection rate and finally 3 taking a dynamic view and considering future effects of current introductions leads unambiguously to more stringent inspections but may give rise to higher or lower tariffs

protection for sale in a developing country democracy vs dictatorship for a genuine small open economy that has experienced both dictatorship and democracy we find support for the predictions of the grossman helpman 1994 protection for sale model in contrast to previous studies we use various protection measures including tariffs the direct measure of the theoretical model and perform both single year and panel regressions using turkish industry level data the government s weight on welfare is estimated to be much larger than that on contributions more importantly we find that this weight is generally higher for the democratic regime than for dictatorship

insurance moral hazard and chemical use in agriculture this paper examines how crop insurance affects corn farmers fertilizer and pesticide use in the u s midwest crop insurance might be expected to affect chemical use because of moral hazard insured farmers may undertake riskier production than do uninsured farmers results suggest that insurance exerts considerable influence on corn farmers chemical use decisions those purchasing insurance applied significantly more nitrogen per acre 19 spent more on pesticides 21 and treated more acreage with both herbicides and insecticides 7 and 63 than did those not purchasing insurance these results suggest that both fertilizer and pesticides may be risk increasing inputs

protectionism versus risk in screening for invasive species abstract i examine the extent to which enforcement of a biosecurity import restriction us border inspections for foreign pests and diseases is used as a protectionist trade barrier the parameters of a structural model of border inspection are estimated using a detailed dataset documenting the outcome of us agricultural border inspections i find that inspections are conducted in a manner that places an implied welfare weight on domestic producers relative to consumers ranging from 1 to 1 63 i also find evidence that the inspection agency takes terms of trade into account when inspecting agricultural imports these results suggest that border inspections are used as a protectionist non tariff barrier

on bias correction in the multivariate sample selection model heien and wessells two step estimator for the multivariate sample selection model has been used extensively during the past 15 years a modified version of it with slightly different selectivity regressors has also appeared in the empirical literature both estimators are unfounded and generally do not correct for the sample selectivity bias as intended but have continued to gain popularity in empirical applications the properties of the modified heien wessells procedure are investigated in both the bivariate and multivariate contexts and the conditions under which this estimator fails to correct for sample selectivity are examined the theoretical properties are demonstrated with a simulated random sample

protection for sale an empirical investigation comment do contributions levels matter for endogenous protection or is the existence of a lobby sufficient are lobbies net benefits from protection identical to their contribution levels or does the level of protection simply reflect contribution levels of supporters and opponents we estimate the influence driven grossman and helpman 1994 and the tariff function findlay and wellisz 1982 models within a unified theoretical framework to examine the contrasting implications derived from these two prominent tariff formation models we find strong evidence that protection is indeed for sale the important new result is however that not only the existence of lobbies matters but also the relative size of the sectoral pro and anti protection contributions using j tests to compare the power of the models directly we cannot reject the null of correct specification of the influence driven model and find evidence of some misspecification in the tariff function model

some empirical evidence on the production level and production cost smoothing models of inventory investment the production smoothing model of inventories has long been the basic paradigm within which empirical research on inventories has been conducted the basic hypothesis embedded in this model is that inventories of finished goods serve primarily to smooth production levels in the face of fluctuating demand and convex cost functions however once we allow for shocks to technology and the costs of producing output firms will also use inventories to shift production from periods in which production costs are relatively high to periods in which production costs are relatively low in this sense inventories can serve to smooth production costs rather production levels in this paper we examine the empirical plausibility of the production level and production cost smoothing models of inventories our basic strategy is to derive and contrast a set of unconditional moment restrictions implied by these models in a way that minimizes the role of auxiliary assumptions regarding market structure and industry demand we find overwhelming evidence against the production level smoothing model and very little evidence against the production cost smoothing mode1 we conclude that the variance of production exceeds the variance of sales in most manufacturing industries because the production cost smoothing role of inventories is quantitatively more important than the production level smoothing role of inventories this abstract was borrowed from another version of this item

assessing cost effectiveness of the conservation reserve program crp and interactions between the crp and crop insurance we examine the u s conservation reserve program crp enrollment design while accounting for the crp s interactions with the federal crop insurance program we find that the current crp is not cost effective despite its intent to balance benefits and costs based on crp contract level data we show that adopting a cost effective enrollment design and incorporating crop insurance subsidies into the crp s environmental benefits index would significantly increase the crp acreage environmental benefits and savings on crop insurance subsidies while leaving government outlay unchanged large geographical redistributions of crp acreage would also occur we further investigate the cost effective design s robustness to crp benefit misspecifications

rent seeking in international trade the great tomato war this paper presents a model of international rent seeking activities by producers in both exporting and importing nations the model is applied to the winter vegetable trade between the united states and mexico an analysis is made of the attempts to form export import coalitions reasons for these failures are given due to past failures to impede trade essentially free trade in winter vegetables between the two countries exists

an empirical analysis of the demand for multiple peril crop insurance knowledge of factors affecting farmer purchases of crop insurance is essential for evaluating the soundness and profitability of crop insurance programs despite this importance the demand for crop insurance has received limited empirical attention the present paper reports on an empirical assessment of the demand for crop insurance by iowa corn producers adverse selection in the insured pool suggests that producers with differing levels of loss risk have different demand elasticities loss risk is included in the empirical analysis and is found to influence the elasticity of demand results show average demand elasticities of about 0 32 for relative insured acres and 0 73 for liability per planted acre implications for the actuarial soundness of the industry are provided

impacts of federal crop insurance on land use and environmental quality this article integrates economic and biophysical models to assess how federal crop revenue insurance programs affect land use cropping systems and environmental quality in the u s corn belt region the empirical framework includes econometric models that predict land conversion and crop choices at the parcel level based on expectation and variance of crop revenues land quality climate conditions and physical characteristics at each site the predictions are then combined with site specific environmental production functions to determine the effect of revenue insurance on nitrate runoff and leaching soil water and wind erosion and carbon sequestration results suggest that federal crop insurance has on average a small effect on conversions of non cropland to cropland and somewhat more significant impacts on crop choice and crop rotation these changes in cropping systems have on average small impacts on agricultural pollution

crop insurance acreage decisions and nonpoint source pollution the redirection of farm policy in the 1996 farm bill has generated much interest in seeking environmentally friendly and economically viable ways to protect farm income agricultural insurance has been suggested as such an instrument this article estimates the effect of crop insurance on crop mix and the resulting change in chemical use in the central nebraska basin providing corn insurance will shift land from hay and pasture to corn which will increase chemical use at the extensive margin this extensive margin effect dominates the effect of crop insurance on the application rate leading to an increase in total chemical use

the demand for multiple peril crop insurance evidence from montana wheat farms an econometric analysis of the demand for multiple peril crop insurance is carried out for a sample of 370 montana wheat farms the study is the first to model the farm s participation and coverage level decisions separately through heckman two stage estimation procedures these decisions are shown to be determined in different ways in addition farms with positive expected returns from insurance make coverage level decisions in different ways from farms with negative expected returns these differences indicate that adverse selection effects limit the efficacy of across the board premium rate increases as mechanisms for reducing loss ratios

how trade politics affect invasive species control abstract trade has become the main mode of transport for many invasive species including diseases and agricultural pests most species are brought to their new homes unintentionally which constitutes a market failure rooted in international trade unless it is practical to drive invasion risk to zero the external costs may justify a tariff in this paper we analyze the political process likely to govern the formation of tariffs so justified using a straightforward incorporation of an invasive species externality into grossman and helpman s gh well known political economy model we show that our measure of disguised protectionism the gap between the optimal tariff and that set in the equilibrium of the political economy game is equal to the tariff that would be set if there were no invasive species and no international disciplines on trade policy the informational needs required to distinguish disguised protectionism from legitimate public goods protection are formidable

the effect of microinsurance on economic activities evidence from a randomized field experiment we report results from a large randomized field to study how access to formal microinsurance affects production and economic develop ment we induce exogenous variation in insurance coverage at the village level by randomly assigning performance incentives to the village animal husbandry worker who is responsible for signing farmers up for the insur ance we find that promoting greater adoption of insurance significantly increases farmers sow production and this effect seems to persist in the longer run moreover the increase in sow production in response to the sow insurance does not seem to be the result of the substitution of other livestock

estimating statistical properties of political economic decisions revelation of criteria implicit in setting policy is addressed in a political economic framework that includes identification and estimation of unknown parameters in the presence of multiple sources of uncertainty policy formation is viewed as an optimization process under which the government maximizes a criterion function subject to market constraints a method for estimating political criterion function weights and their associated standard errors over multiple time periods is presented the approach is illustrated with an empirical example from japanese rice and wheat trade policy

trade diversion from tomato suspension agreements trade barriers can cause output to be diverted to other countries and into other products we study the effect of a voluntary price restraint vpr on mexican tomatoes entering the united states the diversion caused by the vpr is statistically and economically significant representing over four fifths of the direct effects of the trade barrier when the vpr was binding mexico exported more tomatoes to canada the united states cut back on exports while canada increased their exports to the united states the vpr also diverted fresh tomatoes in mexico into paste production which was then exported to the united states des barrieres commerciales peuvent entrainer la diversion de l output vers d autres pays ou d autres productions on etudie la diversion causee par les accords de restriction volontaire des prix arvp des tomates mexicaines entrant sur le marche americain la diversion causee par les arvp a ete statistiquement et economiquement significative representant plus des quatre cinquiemes des effets directs de la barriere tarifaire quand les arvp ont ete contraignants le mexique a exporte plus de tomates au canada les etats unis ont reduit leurs exportations alors que le canada augmentait ses exportations vers les etats unis les arvp ont aussi entraine une diversion des tomates fraiches au mexique vers la production de puree de tomate un produit qui a alors ete exporte vers les etats unis

an empirical analysis of acreage effects of participation in the federal crop insurance program the extent to which crop insurance programs have resulted in additional land being brought into production has been a topic of considerable debate we consider multiequation structural models of acreage response insurance participation crp enrollment and input usage our analysis focuses on corn and soybean production in the corn belt and wheat and barley production in the upper great plains our results confirm that increased participation in insurance programs provokes statistically significant acreage responses in some cases though the response is very modest in every case in the most extreme cases 30 decreases in premiums as a result of increased subsidies provoke acreage increases ranging from 0 2 to 1 1 a number of policy simulations involving increases in premium subsidies are considered

the impact of ad hoc disaster and crop insurance programs on the use of risk reducing conservation tillage practices the paper estimates the impacts of risk reducing government programs on the use of conservation tillage no till and other conservation tillage practices in agriculture conservation tillage can be used to reduce production risk from weather shocks however subsidized crop insurance and disaster payments also reduce risk through financial assistance the paper examines the extent to which risk reducing tillage practices and government programs are substitutes for each other the economic model shows that a decline in average weather conditions increases the use of conservation tillage the economic model also shows that the impact of weather risk and risk aversion on risk reducing practices like conservation tillage are ambiguous the effect depends on the degree that losses are offset by government payments the paper uses county level tillage practice data from the conservation tillage information center for the three state region of iowa nebraska and south dakota results are estimated using instrumental variables and spatial panel data techniques instruments for the program participation and payment data include political variables and weather data the empirical analysis shows that recent disaster and indemnity payments are associated with an increase in the use of no till and a decrease in the use of other conservation till results also show that producers in counties with recent drought and flood events are more likely to use other conservation tillage the results imply that there may be unintended impacts of changes to agricultural policies like disaster payments and crop insurance on the use of on farm conservation practices

effects of crop insurance premium subsidies on crop acreage crop insurance premium subsidies affect patterns of crop acreage for two reasons first holding insurance coverage constant premium subsidies directly increase expected profit which encourages more acreage of insured crops direct profit effect second premium subsidies encourage farms to increase crop insurance coverage with more insurance coverage farms obtain more subsidies and farm revenue becomes less variable as indemnities offset revenue shortfalls so acreage of insured crops likely increases indirect coverage effect by exploiting exogenous policy changes and using approximately 180 000 county crop year observations we estimate the sum of these two effects of premium subsidies on the pattern of u s acreage across seven major field crops we estimate that a 10 increase in the premium subsidy causes a 0 43 increase in the acreage of a crop in a county holding the premium subsidy of its competing crop constant taking into account the small share of premium subsidies in expected crop revenue this subsidy impact is analogous to an own subsidy acreage elasticity of 1 24 which exceeds own price acreage elasticity estimates in the literature one explanation for the larger acreage response to premium subsidies is that insurance causes an indirect coverage effect in addition to a direct profit effect

a policy preference function for government intervention in the u s wheat market this paper estimates a policy preference function that explains the government s choices of target prices government held wheat stocks and public wheat research funding the policy preference function depends on producers surplus consumers surplus and budget expenditures an important innovation in this paper is the inclusion of interactions between public research expenditures and other public policy variables results indicate that the government places a premium of 25 to 45 on the welfare of wheat producers of relative to budget expenditures while wheat consumers welfare is discounted as much as 50 relative to budget expenditures the purpose of this paper is to provide an explanation of government commodity programs stock accumulations and research expenditures in the u s wheat sector the explanation is based on a policy preference function ppf that depends on producers surplus consumers surplus and budget expenditures it is assumed that target prices reductions in or additions to government stocks and public research expenditures are chosen to maximize the policy preference function the central contribution of the paper is the estimation of a function that is consistent with the observed government interventions in the u s wheat market that is the paper explains the observed target prices government sales and public research expenditures as rational behavior by a government which seeks to maximize the estimated policy preference function the approach in this paper is based on the political interest group theories of peltzman and becker applications of these ideas to agriculture include rausser and freebairn s description of the beef industry gardner s 1985 analysis

unintended biological invasions does risk vary by trading partner abstract international trade is the primary conduit for unintentional and damaging species introductions but biogeographic heterogeneity and differences in historical trade exposure across trade partners suggest that not all imports are equally risky we develop an analytical model linking exotic species introductions and discoveries to trade volumes the model is estimated using a novel historical data set on global trade and species introductions by region our estimates support theoretical predictions that trade from different regions poses different risks and that the cumulative number of introductions from a region is a concave function of imports for each trade region we then calculate the marginal and cumulative invasion risk from additional trade simple volume restrictions on imports to reduce nis introductions are not advisable based on coarse cost benefit calculations

input use under cost of production crop insurance theory and evidence there have been a number of previous studies that examined the effects of yield or revenue based crop insurance products on input use of farmers however no study has specifically investigated the input use impacts of a cost of production cop crop insurance policy even though this type of crop insurance is the predominant one used in several other countries outside of the united states such as the philippines and china this article aims to theoretically and empirically examine the effect of a cop crop insurance product on farmers chemical input use our theoretical model suggests that the effect of cop insurance on input use can either be positive or negative with the resulting impact depending on the strengths of a the traditional moral hazard effect of insurance i e an input use decreasing effect versus b the marginal incentives to apply more inputs due to input levels being the main determinant for expected indemnity amounts in this type of insurance i e an input use increasing effect a survey data set from corn farmers in the philippines is then used to empirically illustrate how a particular cop insurance product influences input use in a real life context in this case we find that cop insurance increases the use of chemical inputs e g fertilizers and total chemical expenditure implying that the positive marginal incentive to apply more inputs dominates the negative moral hazard effect

does the samaritan s dilemma matter evidence from u s agriculture the samaritan s dilemma posits a downside to charity recipients may rely on free aid instead of their own efforts anecdotally the expectation of free assistance is thought to be important for decisions about insurance and risky behavior in numerous settings but reliable empirical evidence is scarce we estimate whether the samaritan s dilemma exists in u s agriculture where both private crop insurance and frequent federal disaster assistance are present we find that bailout expectations are qualitatively and quantitatively important for the insurance decision furthermore aid expectations reduce both expenditure on farm inputs and subsequent crop revenue jel d72 h84 q18

import restrictions in the presence of a health risk an illustration using fmd we present a simple model linking infection risk from imports to a tariff the risk causes the exporter of the infected product to face a higher tariff than would otherwise be the case a numerical example is developed for u s beef imports from nations with foot and mouth disease fmd the additional tariffs are sensitive to the specification of risk and the expected magnitude of loss due to an fmd outbreak for a low risk of importing fmd the tariffs levied against the exporter of fmd infected beef are not prohibitive but become so as the risk or expected output loss rises

political economy sectoral shocks and border enforcement in this paper we examine the correlation between sectoral shocks and border enforcement in the united states enforcement of national borders is the main policy instrument the u s government uses to combat illegal immigration the motivation for the exercise is to see whether border enforcement falls following positive shocks to sectors that are intensive in the use of undocumented labor as would be consistent with political economy models of how enforcement policy against illegal immigration is determined the main finding is that border enforcement is negatively correlated with lagged relative price changes in the apparel fruits and vegetables and slaughtered livestock industries and with housing starts in the western united states this suggests that authorities relax border enforcement when the demand for undocumented workers is high

the effects of oil price shocks in a federation the case of interregional trade and labour migration abstract oil price shocks generate heterogeneous effects across and within countries the primary effects of the shocks are on the supply side of the economy in oil importing countries and on the demand side in oil exporting countries however in addition to these direct effects which are widely studied in the literature the oil price shocks also generate spillover effects through trade and labour migration the multi country studies often do not consider the heterogeneities and spillover effects and cannot fully capture the differences in institutions and political structures across countries in this study we investigate the heterogeneous effects of oil price shocks on the canadian economy which includes autonomous oil exporting and oil importing provinces in a federal system under the same institutions monetary policy and political structure furthermore trade and labour migration take place across provinces without significant barriers observed in international relations we set up a panel var model to estimate the dynamic responses of provinces to oil price shocks accounting for the provincial heterogeneities and the spillover effects we also test for asymmetric effects of positive and negative oil price shocks on provinces and examine the differences in the pre and post 2000 periods the results indicate that the oil price shocks generate positive impacts on both oil exporting and oil importing provinces which is in contrast to the results often reported for individual countries or regions the effects are asymmetric for positive and negative oil price shocks and more pronounced in the post 2000 period

tariff equivalent of technical barriers to trade with imperfect substitution and trade costs the price wedge method yields a tariff equivalent estimate of technical barriers to trade tbt an extension of this method accounts for imperfect substitution between domestic and imported goods and incorporates recent findings on trade costs we explore the sensitivity of this revamped tbt estimate to its key determinants substitution elasticity preference for home good and trade cost we use the augmented approach to investigate the recent japan u s apple trade dispute and find that removing the japanese tbt would yield limited export gains to the united states we then draw policy implications of our findings

sodbusting crop insurance and sunk conversion costs we build a real option model that articulates sodbusting incentives arising from risk interventions in the presence of conversion costs the model shows that risk interventions reduce expected costs of switching land use between cropping and noncropping activities and hence incentivize sodbusting based on data for south central north dakota over 1989 2012 our simulations show that offsetting 20 of a cropping return shortfall by a risk intervention increases the sodbusting cost threshold below which sodbusting will occur by 41 or 43 7 acre omitting cropping return risk across time underestimates the sodbusting cost threshold by 23 or 24 35 acre and hence underestimates sodbusting caused by crop production

crop insurance policies and purchases in france while many crop insurance systems have been reformed around the world few academic researches have addressed the determinants of the decision on crop insurance at the farm s micro level in this article both the financial and the agricultural literature lead to the identification of many rationales for the crop insurance decision using data from the period 2003 2006 on a representative survey of french farms fadn rica we investigate the different factors that incite farmers to insure against crop risk we emphasize that the highest risk farms are more likely to have insurance and this decision is positively related to the past amount of claims insurance is subscribed by larger farms because insurance appears too expensive for smaller farms which are indeed naturally less diversified interestingly financial variables such as capital structure or return on investment do not significantly determine the insurance decision

the welfare implications of minimum quality standards previous analysis of the social welfare implications of minimum quality standards has yielded no decisive results in this paper the specific nature of consumer and producer responses to quality standards is incorporated into the analysis both consumer and producer gains are shown to be impossible when consumers can perceive quality before purchase even if low quality produce is diverted to secondary markets standards unambiguously reduce net social benefits the paper explores the possibility that minimum quality standards are a form of rent seeking behavior
