reaction or interaction spatial process identification in multi tiered government structures abstract this paper models horizontal and vertical fiscal externalities in a multi tiered structure of government and implements maximum likelihood and instrumental variables estimation techniques to identify the source of spatial dependence in english local government expenditures the results show that when vertical fiscal externalities among upper tier county authority and lower tier district authority expenditures are explicitly taken into account the estimated magnitude of inter district fiscal interactions is substantially reduced the observed positive spatial autocorrelation among district expenditures can consequently be attributed to a large extent to common reaction to county fiscal policies rather than to actual strategic interaction

performance rating and yardstick competition in social service provision abstract this paper investigates whether national evaluation of decentralised government performance tends by lessening local information spill overs to reduce the scope for local performance comparisons and consequently to lower the extent of spatial auto correlation among local government expenditures it analyses local government expenditures on personal social services in the uk before and after the introduction of a national performance assessment system sspr social services performance rating that would attribute a rating to each local authority the empirical evidence is consistent with the hypothesis that the sspr has reduced local yardstick competition

who gains from capital market integration tax competition between unionized and non unionized countries the welfare effects of capital market integration are examined under a model of tax competition with two asymmetric countries the asymmetry is expressed through the labour market one country has a perfect labour market whereas the other country s labour market is unionized our results indicate that the welfare effects of capital market integration differ depending on whether governments are active or passive in attracting capital in the absence of active governments capital market integration benefits the country with a competitive labour market whereas it harms the unionized country capital market integration benefits both countries if governments are active and compete for mobile capital using taxes subsidies

a nonparametric cost approach to scale efficiency starting with farrell fieldhouse 1962 a host of notiparametric models have been developed for calculation of scale efficiency a common property of these models is that they are specified in terms of input output data duality theory has taught us that technological characteristics may be analyzed from either the primal or the dual cost side the purpose of this paper is to introduce a nonparametric dual method of calculating scale efficiency

supply response in ethiopia accounting for technical inefficiency few empirical studies of supply response using the profit function have accounted for technical inefficiency using farm level panel data from ethiopia this study examines the effect of incorporating technical inefficiency in estimating the supply response of peasant farmers two systems of output supply and input demand equations are estimated and compared the conventional model in which technical efficiency is assumed and another in which technical inefficiency is explicitly incorporated the model with technical inefficiency is preferred on grounds of theoretical consistency and improved estimates although model comparison tests are not conclusive incorporation of inefficiency generally increases the magnitudes and the statistical significance of own price elasticities substantially so in the case of fertilizer and fertilizer intensive crops and alters the priority attached to nonprice factors an important result is that only the specification with inefficiency reveals a significant effect of access to extension services on output only this specification finds that output increases with household size which one expects as the farms in the sample are largely subsistence and producing for own consumption furthermore the results demonstrate that farmers response to incentives is considerably restricted by inefficiency suggesting that the traditional model would overstate response by excluding the efficiency variable

decentralization and intra country transfers in the great recession the case of the european union empirical evidence is found supporting the assignment of the redistribution function to the central government viewing the great recession or recessions in general as a shock it is found that a

accounting for the decline in afdc caseloads welfare reform or the economy we use state level monthly panel data to assess the relative contributions of the macroeconomy and welfare reform in accounting for the 1993 96 decline in aid to families with dependent children afdc caseloads our results suggest that the decline in per capita afdc caseloads is attributable largely to the economic conditions in states and not to waivers from federal welfare policies nationwide we attribute 66 percent of the decline to the macroeconomy however we do find substantial heterogeneity in the impact and timing of alternative waivers on afdc caseloads states with waivers impacting parental responsibilities experienced greater caseload declines than states with waivers that made work more attractive overall our model predicts that had it not been for the influence of economic factors welfare reform would not have led to any decrease in aggregate caseloads

barriers to efficiency and the privatization of township village enterprises abstract qian 2000 and others suggest that post 1994 tax and banking reforms in china combined with the development of markets for allocating resources influenced the economic performance of township village enterprises tves and private enterprises pes this paper uses chinese provincial level data to search for evidence of advantages and or disadvantages offered to tves and pes before and after the 1994 reforms we define a sectoral net income based measure of overall efficiency and decompose the measure into components that highlight the existence of credit constraints output target constraints and labour hiring constraints the results offer empirical support for qian and others explanation of why private enterprises eventually emerged as the dominant institution for allocating resources in post 1994 rural china

testing the taxmimicking versus expenditure spill over hypotheses using english data spatial interaction among local governments in tax setting and public spending decisions is receiving increasing attention in the applied public economics literature spatial interaction models rely on the presence of an externality from local budget making in traditional public finance models external effects originate either from interjurisdictional resource flows due to tax competition for a mobile base or from local public expenditure spill overs into neighbouring jurisdictions however the recent political agency yardstick competition literature has stressed the role of informational externalities between neighbouring jurisdictions and predicted tax mimicry at the local level the actual relevance of the above hypotheses clearly needs to be assessed empirically in this paper an attempt is made at discriminating between alternative sources of local fiscal interaction by using data on the english municipal authorities budgets while both public spending levels and local property tax rates ex

long and short run non parametric cost frontier efficiency an application to spanish savings banks the utilisation rate of installed capacity is a popular concept in both the performance appraisal literature and in publications on industrial organisation however a common consensus has yet to be reached concerning the most appropriate way to measure the capacity utilisation of physical inputs and its final effect on company results on the one hand there are approaches that establish capacity utilisation with reference to the maximum level of production that can be achieved in contrast there are other approaches more strictly related to economic analysis of operating costs in this paper our main objective is to define an analytical process that uses non parametric frontier methodology to provide the distance between the total costs of a given unit and the short run frontier costs as a natural extension of this proposal it is possible to compute the short run inefficiency caused by a non optimal dimension of the fixed inputs we define this as capacityefficiency the proposed evaluation process is applied to spanish savings banks covering the period between 1986 and 1995 throughout the period analysed the greater part of cost inefficiency is due to capacity efficiency 2002 elsevier science b v all rights reserved

value and quantity data in economic and technical efficiency measurement this paper calls attention to the implications of using value data in efficiency measurement through data envelopment analysis dea the main contributions are twofold i it provides a reconciliation of the previous literature on analysing issues of quantity and value data in efficiency measurement ii it provides some guidelines on what to do when these issues arise in a data set

spatial patterns in local taxation tax mimicking or error mimicking this paper tests for mimicry in local tax setting by using a panel data set of the english non metropolitan districts in the 1980s when property tax rate variability across districts was highest the results confirm the presence of large and significant spatial interactions among districts even after allowing for district specific and time effects a district appears to be significantly affected by its neighbours policies a 10 increase in the local property tax rate of a district s neighbours leads to an increase of 4 5 in its own property tax rate on the other hand the absence of correlation in tax rates between lower tier district authorities and upper tier county authorities suggests that the spatial pattern in district tax rates is not simply driven by spatially auto correlated shocks

the effects of the macroeconomy and welfare reform on food stamp caseloads since 1994 there has been an unprecedented decline in the number of people receiving food stamp benefits from a record high of 27 5 million in 1994 the number of food stamp recipients fell over 30 to 18 0 million by mid 1999 during this period the united states has experienced the third longest economic expansion of the twentieth century this has resulted in a dramatic growth of new jobs and the lowest unemployment rate in a generation simultaneously the welfare system has undergone a major transformation beginning in the early 1990s when many states made changes to their welfare programs through federal waivers from aid to families with dependent children afdc requirements the personal responsibility and work opportunity reconciliation act of 1996 prwora furthered these changes by replacing afdc where states contributions were matched by the federal government with a block grant program called temporary assistance for needy families tanf prwora introduced new rules on tanf recipients such as terminal time limits work requirements and personal responsibility measures it also directly changed the food stamp program by ending the eligibility of some recipients and reducing average benefit levels at the same time innovative changes in the delivery of food stamp benefits have been taking place with the introduction of electronic benefit trans

migration and income redistribution responsibilities this study examines whether afdc benefits determine or discourage state to state migration flows in the united states a pooled cross section time series model is developed to estimate afdc benefits in a state and recipients and whether benefits in one state affect benefits in other states a second model using data from the 1980 census and the panel study of income dynamics estimates migration of afdc recipients and the level of benefits in in migration and out migration states both models indicate that small but statistically significant amounts of migration occur which may be quite important but only in the long run movers although small in number are much more likely to move to a state with higher benefits states perceive this migration as important indicating that states should have less control and the federal government more control over income redistribution

do states play welfare games abstract this paper uses a panel of state level annual data from 1983 to 1994 for each of the contiguous united states and the district of columbia to explore the degree to which states simultaneously set welfare benefits using instrumental variables estimation we find substantial empirical evidence that is supportive of the notion of welfare competition furthermore we find that state responses to neighbor benefit decreases tend to be significantly larger in magnitude as their responses to neighbor benefit increases our results therefore have potential implications for public policy in the wake of the increased decentralization of welfare policy associated with the welfare reform of 1996

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

agricultural externalities and environmental regulation evaluating good practice in citrus production economic activity takes place in a scenario characterized by an increasing number of environmental regulations aimed at bringing under control the emission of contaminating wastes in this paper we evaluate the impact of transforming a code of good practice in nitrogen fertilization on spanish citrus fruit farms into an environmental regulation of compulsory fulfilment using data envelopment techniques we calculate unrestricted and environmentally regulated short run maximum profits both profit values are then used to compute an index of the cost of regulation our results suggest that the cost of shifting from a merely recommended practice to a binding rule is low on average the loss of profit computed is only about 4 furthermore we find that farms overall efficiency is low and that the current gap between observed and regulated fertilization practices could be overcome by improving overall management efficiency

spillover effects in local public spending abstractthis paper investigated the fiscal interactions between italian municipalities over the period 2001 11 and found a positive horizontal interdependence in spending decisions the results are robust to different specifications of the spatial neighbours and are confirmed by a natural experiment an earthquake in the abruzzo region of italy in 2009 that creates an exogenous variation in the neighbours spending furthermore there is no evidence of yardstick competition when one considers political effects while a negative relationship is found between spatial interaction and the size of the municipality thus it can be concluded that spillover effects drive the strategic interactions in spending decisions

entry and exit patterns of toxic firms we pair an establishment level dataset from texas with public information available in the toxics release inventory tri to evaluate the standing of dirty industries in texas census tracts with a focus on environmental justice concerns the share of nonwhite residents in a tract is positively correlated with the number of tri reporting firms and an inverse u shaped relationship characterizes the number of tri reporting firms and a tract s median income even after controlling for factor prices and other covariates which might drive firm location decisions entrants that report to the tri are more likely to locate in areas with a higher share of nonwhite residents firms that report to the tri are also more likely to enter areas with a low share college graduates in contrast the number of entrants from industries which do not have tri reporters is negatively related to the percent of nonwhite residents in a tract firms in these non reporting industries are also more likely to enter areas with a high share of college graduates polluters appear to agglomerate raising concerns about both chemical releases being concentrated in certain tracts and also affecting nonwhite dense areas disproportionately the strength of these effects often depend on an urban rural classification with rural areas experiencing the most pronounced concerns moreover tri reporting firms are less likely to exit the market relative to their peers which operate in the same industry but do not need to file tri reports suggesting releases may affect a region in the long run

the spillover effects of state spending abstract this paper estimates the extent to which state spending is influenced by the spending of neighboring states examining several different metrics of neighborliness in order to better identify the channels for interstate spillovers it improves on previous studies by taking advantage of exogenous shocks to state medical spending to abstract from correlated local conditions and by allowing for spatial autocorrelation focusing on mandated increases in medical spending the analysis shows that each dollar of state spending causes spending in neighboring states to increase by almost 90 cents the most predictive measure of neighborliness is the degree of population mobility between states suggesting that rational concerns about adverse migration may drive the interdependence of state spending policy

budget spillovers and fiscal policy interdependence evidence from the states abstract this paper formalizes and tests the notion that states expenditures depend on the spending of similarly situated states we find that even after allowing for fixed state effects year effects and common random shocks among neighbors a state government s level of per capita expenditure is positively and significantly affected by the expenditure levels of its neighbors ceteris paribus a one dollar increase in a state s neighbors expenditures increases its own expenditure by over 70 cents

assistance to the poor in a federal system abstract this paper explores the roles of different levels of government in assisting the poor using a model incorporating utility interdependence the paper first presents some theoretical results indicating how levels of poor relief vary with the extent of mobility of the poor under both centralized and decentralized systems of support it then provides a survey of the empirical work on migration of the poor along with a brief historical discussion of the experience under the english poor laws the concluding section turns to normative issues and contends that mobility of the poor is a basic source of inefficiency in wholly decentralized systems of support this inefficiency along with certain other equity considerations establishes a role for the central government in assistance to the poor

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

a model of welfare competition with evidence from afdc in this paper we test empirically for strategic behavior among the states using the cash support program aid to families with dependent children afdc to motivate the empirical work we adapt wildasin s model of income redistribution 1991 american economic review 81 757 773 to a model of interjurisdictional welfare competition although welfare competition may be generated from different frameworks we choose wildasin s model to illustrate how welfare benefit interdependence is genereated in the context of welfare migration we estimate a representative reaction function for afdc using both cross sections and pooled cross section data after controlling for other determinants of afdc benefit levels and for spatial error autocorrelation we find evidence showing competition 2000 academic press

do local government fiscal spillovers exist evidence from counties municipalities and school districts abstract numerous theories posit that the fiscal decisions of one jurisdiction influence the fiscal decisions of its neighbors the main contribution of this paper is to address empirical difficulties in testing for spillovers using a regression discontinuity design on a newly collected dataset i utilize close elections from this large dataset of local referenda in ohio to isolate the effect of exogenous increases in taxation and spending of one jurisdiction on neighbors fiscal decisions for all jurisdictional types and referenda revenue sources bonds income property and sales tax there is no evidence of spillovers and relatively small effects can be ruled out

local fiscal competition an application to sales taxation with multiple federations abstract local sales tax rates influence the location of retail activity this paper develops a theory and empirical identification strategy for studying sales tax competition with multiple federations as exemplified by multiple counties each containing several cities in addition to strategic interactions with nearby cities and a city s own county city tax rates are influenced by the tax rates of neighboring counties cities react heterogeneously to own county sales tax rates depending on distance to the county border using data on the driving time to county borders and a comprehensive cross section of local sales tax rates i exploit variation in proximity to county borders to identify vertical fiscal competition cities located near county borders react more intensely to their county s tax rate in comparison to towns at the interior an increase in the neighboring county tax rate raises city tax rates in nearby counties

fiscal decentralization and the size of government a european country empirical analysis this article is an original contribution to the understanding of the relationship between fiscal decentralization and government size using a panel data set of the eu 15 countries we analyse the effect of decentralization on aggregate national and subnational government sizes by separating the long run effects of decentralization from its short run dynamics in the long run tax autonomy reduces central expenditure but increases and to a greater extent subnational public expenditure leading to higher aggregate public expenditure we find also that vertical imbalances tend to increase the sizes of subnational national and aggregate governments

using geographic information systems to study interstate competition scholars have proposed two distinct explanations for why policies diffuse across american states 1 policymakers learn by observing the experiences of nearby states and 2 states seek a competitive economic advantage over other states the most common empirical approach for studying interstate influence is modeling an indicator of a state s policy choice as a function of its neighbors policies with each neighbor weighted equally this can appropriately specify one form of learning model but it does not adequately test for interstate competition when a policy diffuses due to competition states responses to other states vary depending on the size and location of specific populations we illustrate with two substantive applications how geographic information systems gis can be used to test for interstate competition we find that lottery adoptions diffuse due to competition rather than to learning but find no evidence of competition in state choices about welfare benefits our empirical approach can also be applied to competition among nations and local jurisdictions

determinants of income diversification amongst rural households in southern mali abstract household level panel data from a representative sample of rural households in southern mali describing the different sources of household income are used to examine the determinants of income diversification a conditional fixed effects logit model is employed in the analysis to control for household specific effects we find evidence that poorer households have fewer opportunities in non cropping activities such as livestock rearing and non farm work and hence less diversified incomes this appears to reflect their relative lack of capital which makes it difficult for them to diversify away from subsistence agriculture the results also indicate that households in remote areas are less likely to participate in the non cropping sector than their counterparts closer to local markets while households with educated heads are more likely to participate in the non farm sector than those with illiterate heads the significance of entry constraints in explaining portfolio diversification suggests that the role of government in making assets as well as improved infrastructure available to poorer households is still essential in promoting income diversification

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

testing for strategic interaction among local governments the case of growth controls this paper helps to fill a gap in the public economics literature by providing empirical evidence on strategic interaction among local governments using the methodology of case et al journal of public economics 52 285 307 1993 the paper focuses on the adoption of growth control measures by cities in california and looks for evidence of policy interdependence in these choices the data are drawn from an elaborate survey of growth control practices in california cities conducted by glickfeld and levine regional growth local reaction lincoln institute of land policy cambridge ma 1992 the survey results are used to compute an index of the stringency of growth controls in each city which serves as the dependent variable for the study

in search of yardstick competition a spatial analysis of italian municipality property tax setting this paper uses italian local government data to test for fiscal interaction arising from yardstick competition to discriminate yardstick competition from competing theories of strategic interaction we account for the incentives and constraints generated by the electoral system in particular for the presence of term limits and the size of the majorities supporting the mayors estimation of a local property tax setting equation uncovers positive spatial auto correlation in local tax rates of jurisdictions where the mayors run for re election in uncertain contests while interaction is absent where either mayors face a term limit or are backed by large majorities

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

government spending and the distribution of economic growth in the united states total government spending and especially government social spending has increased greatly over the last 50 years what effect this has had on economic growth is a subject of intense debate among politicians policymakers and economists however there has been less attention paid to the distributional effects of government spending even though economic inequality has grown greatly over the last generation and much social spending is at least indirectly intended to reduce inequality the effects of government social spending in the united states on growth in family income at deciles of the income distribution were estimated the results suggested that social spending but not non social spending was likely to increase growth in family income per capita measured over 10 year intervals the largest effects of social spending were for deciles below the median income at no point in the distribution does social spending have a negative effect

competition for migrants in a federation tax or transfer competition this paper provides an analysis of competition for migrants competing in taxes transfers renders migration flows less more elastic with respect to changes in fiscal policy jurisdictions with aligned preferences i e jurisdictions that maximize the interest of the same type of households either mobile or immobile households prefer to reduce the competitive pressure and compete in taxes jurisdictions with distinct preferences on the other hand prefer to expose themselves to more competitive pressure and compete in transfers this paper offers insights into the optimal use and design of transfers and helps interpret existing empirical evidence

decentralized redistribution in a laboratory federation abstract the idea of laboratory federalism provides a strong argument in favor of fiscal decentralization it views autonomous jurisdictions in a federation as laboratories where new policies can be tested at low risk for the entire system if successful these policies will spread out by imitation otherwise they will be discarded studying this idea in a dynamic setting of fiscal competition we show that due to externalities between jurisdictions policies that appear successful and are therefore mimicked do not necessarily enhance welfare and vice versa specifically in the classical framework of decentralized rich to poor income redistribution with labor mobility the long run outcome entails a complete breakdown of redistribution with zero subsidies to the poor everywhere

misaligned incentives and the scale of incarceration in the united states abstract the incarceration rate has increased substantially in the united states between the 1980s and the 2000s in this paper i explore an institutional explanation for this growth the fact that costs of incarceration are not fully internalized typically prison is paid for at the state level but county employees such as judges prosecutors or probation officers determine time spent in custody i exploit a natural experiment that shifted the cost burden of juvenile incarceration from state to counties keeping overall costs and responsibilities unchanged this resulted in a stark drop in incarceration and no increase in arrests suggesting an over use of prison when costs are not internalized the large magnitude of the change suggests that misaligned incentives in criminal justice may be a significant contributor to the current levels of incarceration in the united states

incumbent behavior vote seeking tax setting and yardstick competition this paper develops a model of the political economy of tax setting in a multijurisdictional world where voters choices and incumbent behavior are determined simultaneously voters are assumed to make comparisons between jurisdictions to overcome political agency problems this forces incumbents into a yardstick competition in which they care about what other incumbents are doing we provide a theoretical framework and empirical evidence using u s state data from 1960 to 1988 the results are encouraging to the view that vote seeking and tax setting are tied together through the nexus of yardstick competition

public spending interactions and local politics empirical evidence from french municipalities this paper aims at testing whether there exist spending interactions between french municipalities by estimating a dynamic panel data model our results suggest that there are some interactions between neighbouring municipalities as regards primary and investment expenditures a positive relationship between municipalities wage bill and un employment rates is likely to stress a rise of temporary employment in those municipalities that suffer from social troubles further the estimation results show that these interdepen dences also exist between cities whose mayors have the same partisan affiliation finally our results confirm the opportunistic behaviour of local governments which increase all categories of public spending in pre electoral periods

the relation of farm size and government programme benefits an application of data envelopment analysis to policy evaluation data envelopment analysis is used to establish comparisions of maximum profit without and with participation in government progarammes a measure of a farm s ability to survive returns on equity is used to measure the benefit received from participation in government programmes density functions are estimated with kernel density estimation using bootstrap samples and weighted regressions are used to test density estimation using bootstrap samples and weighted regressions are used to test the equality of mean benefits between different size groups the results indicate that almost all farms that could be considered of commercial size receive the same benefit from participation in government programmes

games the states don t play welfare benefits and the theory of fiscal federalism fiscal federalism theory predicts that states will behave strategically in welfare programs because voter demand for welfare is sensitive to tax price while the tax price itself changes because of welfare induced migration this paper tests these propositions on afdc in the united states for a panel from 1982 88 using new models for the determination of the recipiency ratio the tax price and composite neighbors the data do not support any substantial tax price elasticity of demand for welfare estimates of migration effects on tax price are found to be sensitive to specification copyright 1995 by mit press

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

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

welfare reform and the race to the bottom theory and evidence economists have argued that welfare migration leads to a race to the bottom in the choice of welfare benefits although a system of federal matching grants can remedy this problem the recent welfare reform law replaced the existing matching grant structure with block grants a policy change that appears undesirable to judge whether this critique of welfare reform is justified this paper evaluates the evidence in favor of a race to the bottom after explaining the theoretical effects of welfare migration the paper surveys the empirical evidence on the occurrence of such migration concluding that the evidence is mixed the discussion also considers recent empirical tests for strategic interaction which show that benefit levels in nearby states affect a given state s benefit choice the most plausible source of such interaction is a concern about welfare migration which leads policymakers to look at benefits in neighboring states when making their own choices judging that the evidence appears consistent with the existence of a race to the bottom the paper concludes that the demise of matching grants may be undesirable from a policy perspective
