a dynamic model of welfare reform a dynamic structural model of labor supply welfare participation and food stamp participation is estimated using the 1992 1993 and 1996 panels of the survey of income and program participation details of various policies including welfare time limits work requirements and earned income tax credit eitc are incorporated formally in the budget constraint policy simulations reveal that the economy accounts for half of the increase in the labor supply of female heads of family between 1992 and 1999 a time limit results in a larger efficiency gain than a work requirement or a direct reduction in welfare benefits a reform package can lead to both a reduction in the government expenditure and an improvement in utility the eitc expansion results in a substantial efficiency gain among individuals with the lowest expected wage these individuals are almost unaffected by the economic expansion but their income and utility increase significantly under the reform package

beyond gdp the quest for a measure of social welfare this paper critically examines the various approaches to the measurement of individual well being and social welfare that have been considered for the construction of alternatives to gdp special attention is devoted to recent developments in the analysis of sustainability in the study of happiness in the theory of social choice and fair allocation and in the capability approach it is suggested in the conclusion that although convergence toward a consensual approach is not impossible for the moment not one but three alternatives to gdp are worth developing jel i31 e23 e01

efficiency and equity effects of reforming the british system of direct taxation a utility based simulation methodology the simulation model presented in this paper shows how an estimated utility index defined over net income and leisure can be used to replicate labor supply behavior individual by individual this methodology is used to evaluate the efficiency and equity effects of two specific revenue neutral reforms of the british system of direct taxation the first reform involves abolishing the married m an s tax allowance the second abolishes this allowance only when the wife exhausts her own tax allowance the second reform is the most efficient and it may also be preferable on distributional grounds copyright 1988 by the london school of economics and political science

marginal commodity tax reforms a survey as noted 30 years ago by martin feldstein optimal taxes may be useless for practical purposes and emphasis should instead be placed on the possibility of enhancing welfare by reforming existing tax rates in this perspective marginal commodity tax reforms are gaining increasing attention due to political and economic constraints on large reforms of direct or indirect taxation in this paper we summarize the main features and results of the literature on marginal commodity tax reforms pioneered by ahmad and stern further developed by yitzhaki and thirsk and recently reinterpreted by makdissi and wodon we establish new links to other fields of research namely the literature on the use of equivalence scales and on poverty measurement we also critically examine some issues associated with the implementation of marginal tax reforms with special reference to the calculation of welfare weights and revenue effects finally we suggest directions for future research on poverty reducing commodity tax reforms

the proper scope of government theory and an application to prisons when should a government provide a service in house and when should it contract out provision we develop a model in which the provider can invest in improving the quality of service or reducing cost if contracts are incomplete the private provider has a stronger incentive to engage in both quality improvement and cost reduction than a government employee has however the private contractor s incentive to engage in cost reduction is typically too strong because he ignores the adverse effect on noncontractible quality the model is applied to understanding the costs and benefits of prison privatization

political risk and export promotion evidence from germany political risk represents an important hidden transaction cost that reduces international trade this paper investigates the claim that german public export credit guarantees hermes guarantees mitigate this friction to trade flows and hence promote exports we employ an empirical trade gravity model where we explicitly control for political risk in the importing country in order to evaluate the effect of export guarantees the idea behind export promotion through public export credit agencies ecas is that the private market is unable to provide adequate insurance for all risks associated with exports as a consequence firms export activities are limited in the absence of insurance provision using a novel data set on guarantees we estimate the effect of guarantees in a static and dynamic panel model we find a statistically and economically significant positive effect of public export guarantees on exports which indicates that export promotion is indeed effective furthermore political risk turns out to be a robust determinant of exports and hence should be taken into account in any empirical model of trade

dalton improving indirect tax reform a tax reform is dalton improving if it improves social welfare for all possible social welfare functions that conform to hugh dalton s principle of transfers according to this principle there exists a prior social ranking of households and a transfer is approved if it it distributes from high ranking rich to low ranking poor households without altering the ranking itself in this paper the authors develop a procedure for identifying marginal dalton improving reforms in the context of indirect taxation the methodology is illustrated using data on excise taxes in the united kingdom copyright 1995 by american economic association

labour supply specification and the evaluation of tax reforms this paper investigates the practical importance of the functional specification of labour supply equations for the analysis of tax benefit reform we consider two labour supply specifications one derived from stone geary preferences and the other from a generalisation that relaxes some of the more critical restrictions in that model we use these equations to contrast the effects of two reforms to the u k income tax system one involves income effects almost exclusively while the other implies a significant number of large increases in marginal tax rates

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

household energy prices and inequality evidence from german microdata based on the easi demand system abstract this paper studies the distributional effects of rising energy costs for households in contrast to most of the previous literature our specification differentiates between electricity and heating demand and still models other consumption goods in realistic detail we use a yet unexplored data set on household expenditures in germany and extend the recently developed easi demand system for the analysis of inequality and welfare at the individual and social level the easi system reveals non linearity of engel curves which when neglected can lead to biased estimates of distributional effects we find that increases in heating prices are more regressive than those in electricity furthermore current proposals for social tariffs are found to be less effective than targeted compensation schemes

aggregate consumer behaviour and the measurement of inequality this paper presents an approach to inequality measurement based on an econometric model of aggregate consumer behaviour the novel feature of this model is that systems of individual demand functions can be recovered uniquely from the system of aggregate demand functions we present methods for evaluating social welfare based on an explicit social welfare function this social welfare function incorporates measures of individual welfare based on indirect utility functions for all consumer units we develop indexes of inequality based on actual and potential levels of social welfare

the economics of development a survey i the subject our definition of the subject will be the use of economic analysis to understand the economies of poor or developing countries this includes in particular how standards of living in the population are determined and how they change over time and further how policy can or should be used in the influence of these processes the definition contains in principle much or most of analytical methods in economics insofar as they can be put to use in the examination of the issues of interest this is as it should be but it poses a problem for a survey in a journal a comprehensive treatment is infeasible so we shall follow a different route the survey will focus on what i take to be the major themes and approaches which characterise the productive aspects of the subject there is therefore no pretence at being exhaustive the purpose is rather to highlight some of the advances many of these have been of real substance there are a number of possible purposes for a survey and it is important to be clear at the outset for whom it is intended what it is and what it is not this survey is addressed to economists and students of economics who know the tools of their trade but not necessarily how they have been applied to and fashioned for the analysis of the economics of developing countries it is a description of the ways in which problems can be productively formulated and approached in terms of examples chosen for their intrinsic importance and interest the vastness of the subject means that we have to be highly selective it does not seek to provide a summary evaluation of the current view of the appropriate response to immediate policy questions it is not a history of thought nor a research manifesto nor an attempt to adjudicate or settle the major debates where they arise naturally from the major purpose some judgements on these subjects will be offered but they do not themselves constitute the primary intent of this survey there are three lines of enquiry or sets of questions which have i suggest been distinctive of the most fruitful work in development economics they will

welfare analysis of tax reforms using household data abstract this paper discusses a methodology for calculating the distribution of gains and losses from a policy change using data for a large sample of households estimates are based on the equivalent income function which is money metric utility defined over observable variables this enables calculations to be standardised and a computer program to compute the statistics presented in the paper is available for a general demand system equivalent income is related to measures of deadweight loss and standard errors are computed for each of the welfare measures an application to u k data for 5 895 households is given which simulates a reform that involves eliminating housing subsidies

an index of inequality with applications to horizontal equity and social mobility horizontal equity and social mobility are discussed in terms of a non utilitarian social welfare function which takes account of the process by which an ex ante distribution is mapped into an ex post distribution by the tax system for example an index of inequality is proposed which decomposes into two components corresponding to vertical and horizontal equity respectively a functional form for the social welfare function is derived for the purposes of empirical work and an application to data for 5895 uk households is presented the paper contains a theoretical application of the index to a model of optimal taxation it is conventional to assess the merits of alternative public policies in terms of a trade off between equity and efficiency in practice however a change in say the tax system involves three effects first it may have incentive or disincentive effects leading to efficiency gains or losses secondly it may alter the distribution of welfare levels thirdly it may alter the ranking of individuals or households within the distribution these three effects correspond to efficiency vertical equity and we shall argue certain aspects of horizontal equity respectively and any assessment of a tax change must take into account all three the principal assumption of this paper is that government is concerned about the trade off between these three effects a strict utilitarian is concerned only with the consequences of an action and in the evaluation of a particular reform a utilitarian measure of social welfare is defined over the vector of ex post utilities no account is taken of the process by which the vector of ex ante utilities is mapped into the ex post vector and no ethical status is awarded to the ex ante distribution one does not have to adopt an entitlement theory of justice to believe that the utilitarian approach may ignore some relevant considerations such as the fairness of the redistributive process a striking example of this arises in the model used by mirrlees 11 to examine optimal income taxation in that model individuals have identical preferences defined over consumption and leisure and differ only in respect of their potential wage rates or ability levels clearly in the absence of taxation individual utility is an increasing function of ability suppose the government uses redistributive lump sum taxes to achieve the first best optimum then as mirrlees 11 12 shows the first best optimum for a utilitarian social welfare

housing reform in urban china efficiency distribution and the implications for social security we investigate the distribution of a measure of housing consumption among public tenants in cities of two chinese provinces using household survey data we find the resulting distribution roughly consistent with the outcome of a market rental system for fixed supply and ces preferences there is surprisingly little evidence of allocative inefficiency in the present bureaucratic allocation system we estimate the possible effects of market oriented housing reform under alternative assumptions about the system of cash transfers used to compensate for a move to market rents we investigate the distributional impact of reform and the likely need for supplementary cash benefits for low income households

measuring the inefficiences of tax systems abstract the properties of the procedure for measuring inefficiency developed by debreu 1951 1954 are summarised and the advantages of such an input based approach in analysing taxation discussed exact expressions for the debreu measure of deadweight loss are derived and the measure proposed by kay 1980 shown to be a special case the approach is pursued to construct and interpret a measure of the overall welfare loss from taxation which decomposes conveniently into efficiency and distributional components in one special case the corresponding index of total effectiveness is the product of debreu s coefficient of resource utilisation and an atkinson equality index

a decade of tax and benefit reforms in sweden effects on labour supply welfare and inequality sweden has experienced a sequence of tax and benefit reforms during the last decade in this paper we evaluate these reforms from labour supply welfare and inequality points of view we depart from a household labour supply model simulation of the model reveals that tax and benefit reforms have led to a considerable reduction of the excess burden regarding social welfare and inequality we show that the results depend to a large extent on the income inequality measure and the measure of social welfare as well as the income concept household disposable income or money metric utility

measuring welfare changes in settings with imposed quantities abstract an intuitively attractive money metric utility measure is developed which is applicable in settings where individuals receive fixed quantities of one or more goods one use of this measure is in cost benefit analyses of imposed quantity changes the approximate measures typically used are shown to be subject to relatively large approximation errors however techniques are presented which can always be used to numerically evaluate the exact welfare measure provided that one knows the uncompensated demand function s or marginal willingness to pay function s of individuals

three sides of harberger triangles prevailing economic wisdom is highly critical of injudicious tax policies or government regulations uncorrected externalities unchecked monopolistic practices and various other market failures when economists are challenged to quantify the economic costs of associated price distortions it is standard practice and has been since the 1960s to use a small number of assumptions and selected elasticities to estimate areas of the relevant harberger triangles this simple and straightforward exercise has numerous applications and the virtue of producing answers rather than conjectures harberger triangles come in many shapes and sizes figure 1 offers an illustration of such a triangle for the simple case of an excise tax point a of figure 1 at which the demand and supply schedules intersect denotes market equilibrium in the absence of the tax with quantity q1 transacted at price p1 introduction of an excise tax at rate t payable by firms selling the commodity shifts the supply schedule upward by t at the new market equilibrium firms sell q2 units of the commodity at a market price of p2 receiving after tax p3 a p2 0 t market equilibrium at point a in figure 1 has the feature that marginal consumption benefits equal marginal production costs the excise tax drives a wedge between marginal benefits and marginal costs at consumption level q2 consumers are willing to pay any amount up to p2 for additional units of the good and suppliers would readily provide additional units of the good for any price of p3 or greater but these additional transactions do not take place due to the effect of the tax wedge the loss associated

credit support for export robust evidence from the czech republic the topic of this paper is quite a novel one it is one of few empirical academic papers dealing with export credit moreover it is the first analysis of this kind which focuses on transition economies the paper deals with export credit promotion in the czech republic the development and structure of czech trade and export support is presented first followed by an econometric analysis of the gravity model of czech republic trade a panel of 160 countries in 1996 2008 is analysed and two gravity models of exports for the czech republic are estimated the static model by fixed effects lsdv estimator and the dynamic model by system gmm due to ambiguous conclusions we assume that the behaviour of our explanatory variables is not uniform and our data set behaves as a mixture of countries with heterogeneous behaviour this means that traditional techniques of estimation which include all observations into one model do not give significant results thus we use robust techniques of estimation that solve the problem of heterogeneous patterns in data sets out of several possibilities we use the least trimmed squares estimator lts with a leverage point we show that guarantees are a significant factor that influences positively the volume of exports in the czech republic moreover there exist more variables that affect the size of exports in the czech republic market forces described by gdp distance political risk or gross fix capital formation are significant in our econometric model we find that higher gdp shorter distance or lower political risk have a positive impact on czech exports

distributional consequences of fisheries regulations an empirical methodology for evaluating fisheries regulations in terms of both rent gains and employment losses is proposed a royalty tax and a change in catch distribution among competing vessel types are compared with the status quo of restricted access the case study is the british columbia commercial salmon fishery results suggest that rent gains associated with the alternatives are not always sufficient to compensate for losses in fishing income

distributional effects of housing subsidies in the united kingdom this paper examines the first round distributional effects of subsidies to public sector tenants and tax concessions to owner occupiers in the united kingdom excluding income related housing benefits the average values per family of the two are found to be of similar magnitude local authority rates property taxes are found to have provided a roughly equivalent offset to the shortfall from economic rents for local authority tenants and the lack of taxation of owner occupiers imputed rents their abolition substantially improves the position of housing compared with other forms of consumption or investment

do political parties matter evidence from u s cities are cities as politically polarized as states and countries no is the answer from our regression discontinuity design analysis which shows that whether the mayor is a democrat or a republican does not affect the size of city government the allocation of local public spending or crime rates however there is a substantial incumbent effect for mayors we investigate three mechanisms that could account for the striking lack of partisan impact at the local level and find the most support for tiebout competition among localities within metropolitan areas

applied welfare economics with discrete choice models economists have been paying increasing attention to the study of situations in which consumers face a discrete rather than a continuous set of choices such models are potentially very important in evaluating the impact of government programs upon consumer welfare but very little has been said in general regarding the tools of applied welfare economics indiscrete choice situations this paper shows how the conventional methods of applied welfare economics can be modified to handle such cases it focuses on the computation of the excess burden of taxation and the evaluation of quality change the results are applied to stochastic utility models including the popular cases of probit and logit analysis throughout the emphasis is on providing rigorous guidelines for carrying out applied work this abstract was borrowed from another version of this item

on reforming the welfare system abstract using a simulation model for a small open economy quebec 1986 various negative income tax nit and workfare schemes are compared from the point of view of efficiency and equity the main finding is that there exist workfare schemes that are superior both to the quebec regime of 1986 and to a nit characterized by a 100 percent implicit tax rate however these workfare schemes are dominated by some nit programs this suggests that it may be necessary to have work requirements that vary across socio demographic classes for a workfare plan to be superior to any nit combining workfare with an nit could also be the prescription

the relationship between the marginal cost of public funds and marginal excess burden a large literature has recently developed which attempts to measure the marginal cost shadow price of public funds the motivation for much of this literature is the recognition that many of the tax instruments used by governments generate substantial amounts of excess burden deadweight loss jerry a hausman 1981 for example estimates that for an average prime aged american male with a wage of ten dollars in 1975 the excess burden generated by the federal income tax was over fifty percent of the revenue raised from taxing that individual one might suspect that such large excess burden estimates would require a change in the way government project costs are calculated in benefit cost analysis if the revenue required to finance a project is raised through distortionary taxation then intuition would suggest that the excess burden generated by the increase in tax rates needed to finance the project should be incorporated into the cost of the project however this analysis is not entirely consistent with the theoretical literature on the optimal provision of public goods which are financed by distortionary taxation when distortionary taxes are used to finance public goods and the level of public good provision does not affect consumption of the taxed goods the standard samuelsonian rule which equates the sum over consumers of the marginal rates of substitution between a private good and a public good with the marginal rate of transformation between the two goods must be modified to account for the marginal effect of increases in tax rates on the revenue raised from the existing taxes 2 the intuition behind this result is that we need to correct for indirect leakages from existing government revenue sources when considering an incremental expenditure if the increase in tax rates needed to finance the project causes a reduction in the revenue raised by the current tax structure then we need to account for this loss in calculating the cost of the project it is important to note that this result concerns the values of uncompensated demand elasticities an example first provided by atkinson and stern 1974 illustrates this point consider a world where the only tax is on labor earnings and incremental expenditure on the public good does not affect the demand for leisure in this case the marginal rate of transformation will overstate the cost of the public good as long as the uncompensated wage elasticity of labor supply is negative this is because an increase in the tax rate causes an increase in labor supply leading to an indirect increase in government revenue from the excess burden perspective described earlier this example is very puzzling it is well known that even if the uncompensated own price elasticity of a good is zero a tax on that good can still result in a large deadweight loss we instead need the compensated elasticity to be zero to ensure that there will be no excess burden however the department of economics university of california davis ca 95616 this paper is based on chapter two of my dissertation at the university of wisconsin madison i wish to thank the members of my dissertation committee martin david robert haveman chair and arthur goldberger for very helpful advice and comments i have also benefited from comments by don fullerton and bruce hamilton an anonymous referee provided unusually helpful comments and corrected an error in the figure 1don fullerton 1989 provides a recent survey and analysis of this literature 2this is shown by anthony atkinson and nicholas h stern 1974 and david e wildasin 1979 the effect of provision of the public good on consumption of the taxed goods must also generally be taken into account

the design of direct taxation and family benefits abstract the subject of this paper is the design of the personal income tax and social security benefits that vary with the size of the family it is concerned with the analytical problems of policy design that arise from constraints on the instruments which may be used from differences in social judgements about the desirability of redistribution and from differences of view about the disincentive effects of taxation the paper considers these issues in the context of the french tax benefit system and the implications of the french system being harmonised towards certain features of the british system

the measurement of deadweight loss in an open economy there are many approaches to the measurement of the resources wasted in an economy arising from an inappropriate system of taxation and government regulation the existing literature on this topic is too voluminous for us to summarize in this introduction 1 in the remainder of this introduction therefore we simply outline what we hope to add to the literature in this paper at the outset it should be mentioned that we are going to consider only the deadweight loss generated by inappropriate systems of taxation the losses generated by monopolistic behaviour on the part of producers could be modelled in a similar fashion but we leave this generalization to the reader 2 in section i below we illustrate our two alternative measures of deadweight loss by means of some simple diagrams from the diagrammatic viewpoint neither loss measure has a clear cut advantage over the other however when we move to our algebraic analysis of the loss measures and to quadratic approximations then it turns out that our allais debreu loss measure allais 1943 pp 610 616 debreu 1951 1954 has a clear cut advantage over the hicks boiteux measure hicks 1941 1942 boiteux 1951 at least when the number of households in the economy exceeds one it should be mentioned that we are restricting our attention to loss measures that are well defined when a there is an arbitrary number h of households in the economy b there is an arbitrary number n of domestic goods and an arbitrary number m of internationally traded goods in the economy 3 and c there is an arbitrary number k n of constant or diminishing returns to scale sectors in the production sector of the economy the last restriction turns out to be important because the case where n the number of domestic goods equals k the number of sectors leads to measures of deadweight loss that have substanitally lighter informational requirements in section ii we lay out our model of the economy using duality theory in order to reduce the number of variables and equations in section iii we develop a measure of loss arising from tariff and tax distortions which is due essentially to boiteux 1951 conceptually the boiteux loss measure is simply a sum of hicksian 1941 1942 p 128 equivalent variations applied to each consumer s expenditure function so we call our loss measure a hicks boiteux loss measure however boiteux 1951 p 128 provided a quadratic approximation to his loss measure which decomposed into additive consumer and producer terms whereas hicks and others did not accomplish this additional step we obtain the same kind of decomposition as boiteux but generalized to an open economy 5 it should be noted that the loss measure developed in this section collapses down to the standard

exact consumer s surplus and deadweight loss consumer s surplus is a widely used tool in applied welfare economics both economic theorists and cost benefit analysis often use consumer s surplus despite its somewhat dubious reputation the basic idea is to evaluate the value to a consumer or his willingness to pay for a change in price of a good from say pricep to pricep because price changes affect consumer welfare an evaluation of this effect is often a key input to public policy decisions yet consumer s surplus is probably the most controversial of widely used economic concepts both paul samuelson and ian little conclude that the economics profession would be better off without it it is my feeling of the situation that substantial agreement exists on the correct quantities to be measured the amount the consumer would pay or would need to be paid to be just as well off after the price change as he was before the price change the quantities correspond to john hicks compensating variation measures an alternative measure which takes ex post price change utility as the basis of comparison is hicks equivalent variation the controversy arises in the measurement of these quantities the usual measurement procedure is to use the area to the left of the marshallian market demand curve between two price levels jules dupuit originated this measure of welfare change and alfred marshall and hicks derived appropriate conditions for its use the primary condition for the area to the left of the demand curve to correspond to the compensating variation is to have constant marginal utility of income marshall gave this condition and if it holds the same quantity will be derived as the area to the left of the compensated hicksian demand curve this area to the left of the compensated demand curve is exactly what the compensating variation and equivalent variation measure thus the constant marginal utility of income is a sufficient condition for marshallian consumer s surplus to be equal to hicks consumer s surplus in this case arnold harberger s plea to use the welfare triangle as one half times the product of the price change times the quantity change to measure deadweight loss corresponds to the correct theoretical amount of welfare change in a recent paper robert willig derives bounds for the percentage difference between the correct measure of either the compensating or equivalent variation and the marshallian measure derived form the market demand curve his bounds which depend on the income elasticity of demand for the single good in the region of price change being considered as well as the proportion of the consumer s income spent on the good demonstrate that the marshallian consumer s surplus is often a good approximation to hicks consumer s surplus the fact that the proportion of the consumer s income spent matters as well as the income elasticity was first pointed out by harold hotelling willig contends that the approximation error will be less than the errors involved in estimating the demand curve thus he hopes to remove the need for apology that applied economists often need to give to theorists who remark on the inappropriateness of using marshallian consumer s surplus to measure welfare change however in this paper i show that for the case primarily considered by willig of a single price change which is also the situation in which consumer s surplus is often used in applied work no approximation is necessary professor of economics massachusetts institute of technology and research associate national bureau of economic research i would like to thank peter diamond erwin diewert daniel mcfadden robert merton robert solow hal varian joel yellin and the referees for help and comments research support from the national science foundation is acknowledged the reason that we still have two rather than one of samuelson s six measures of consumer s surplus arises from an index number problem of the correct basis for the welfare comparison i will give both measures but plan to concentrate on the compensating variation

optimal tax and public investment rules for congestion type of externalities optimal government policy is considered in a second best framework where consumers and producers cause an externality of the congestion type and income distribution issues are taken into account the theoretical results of the optimal tax literature are adapted using the concept of the net social pigouvian tax an illustrative age model uncovers the relative importance of its components the model demonstrates that the level of the externality tax does not depend strongly on distribution concerns as reoptimization of the other taxes ensures that the income distribution objective is reached the model also allows us to study the interaction between externality taxes and public abatement

optimal non linear income taxation for the alleviation of income poverty there has been much discussion recently of structuring tax and transfer programs to ensure that resources go to the poor with minimal leaks to the nonpoor the poor have no incentive to earn income with 100 percent marginal tax rates but how high or low the marginal rate of taxation should be and how they should vary with income is a complex issue and opinions vary social security schemes that withdraw benefits represent an extremely high effective marginal tax rate other schemes call for relatively low marginal tax rates at the bottom of the income distribution which tax transfer schedule does most to reduce poverty the issue is one of optimal nonlinear income taxation the authors show that one of the key theoretical results of the welfarist literature is overturned if it is desirable for everybody to work the optimal marginal tax rate on the very poorest individuals is strictly negative they argue that the nonwelfarist perspective points toward lower marginal tax rates in the lower part of the income distribution than does the welfarist perspective but numerical simulations suggest that the effect is of limited quantitative significance using conventional functional forms and parameter values optimal marginal tax rates on the poor are in the 60 70 percent range

race segregation and postal employment new evidence on spatial mismatch abstract the spatial mismatch hypothesis posits that employment decentralization isolated urban blacks from work opportunities this paper focuses on one large employer that has remained in the central city over the twentieth century the u s postal service we find that blacks substitute towards postal work as other employment opportunities leave the city circa 1960 the response is particularly strong in segregated areas where black neighborhoods are clustered near the central business district furthermore this pattern only holds for non mail carriers many of whom work in central processing facilities more recently the relationship between black postal employment and segregation has declined suggesting that spatial mismatch has become less important over time

do we care a study of canada s indirect tax system this paper builds on the optimal taxation literature of diamond and mirrlees 1971 ahmad and stern 1984 and christiansen and jansen 1978 using ethically defensible measures of social welfare the effective redistribution due to the canadian indirect tax system is measured and directions of welfare enhancing tax reform are uncovered using micro data from the family expenditure survey this study finds that surprisingly the existing canadian indirect tax system is neither progressive nor regressive rather the implicit government preferences as reflected in the indirect tax system show no aversion to cross class income inequality

labour supply welfare rankings and the measurement of inequality abstract this paper presents an analysis of inequality using utility based measures of welfare derived from different approaches to modelling household labour supplies the almost ideal demand system specification of preferences is selected for the estimation of a neoclassical household model and of individual decision models which incorporate different assumptions concerning the intra household distribution of income using the rosen 1976 tax perception methodology the study also explores the implications of a model which does not constrain time at home to leisure welfare rankings and inequality measures defined on equivalent income are compared for each type of model the analysis uses australian unit record data on 3 352 households drawn from the australian bureau of statistics 1981 82 income and housing sample survey file the results indicate the sensitivity of welfare orderings and inequality measures to the choice of decision model and to the specification of lump sum transfers between family members a comparative study of equivalent incomes and selected money income variables also illustrates the limitations of observed household and individual incomes as welfare indicators for the analysis of inequality and for policy design

economic impacts of new unionization on private sector employers 1984 2001 economic impacts of unionization on employers are difficult to estimate in the absence of large representative data on establishments with union status information estimates are also confounded by selection bias because unions could organize at highly profitable enterprises that are more likely to grow and pay higher wages using multiple establishment level data sets that represent establishments that faced organizing drives in the united states during 1984 1999 this paper uses a regression discontinuity design to estimate the impact of unionization on business survival employment output productivity and wages essentially outcomes for employers where unions barely won the election e g by one vote are compared with those where the unions barely lost the analysis finds small impacts on all outcomes that we examine estimates for wages are close to zero the evidence suggests that at least in recent decades the legal mandate that requires the employer to bargain with a certified union has had little economic impact on employers because unions have been somewhat unsuccessful at securing significant wage gains

the value of school facility investments evidence from a dynamic regression discontinuity design author s cellini stephanie riegg ferreira fernando rothstein jesse abstract despite extensive public infrastructure spending surprisingly little is known about its economic return in this paper we estimate the value of school facility investments using housing markets standard models of local public goods imply that school districts should spend up to the point where marginal increases would have zero effect on local housing prices our research design isolates exogenous variation in investments by comparing school districts where referenda on bond issues targeted to fund capital expenditures passed and failed by narrow margins we extend this traditional regression discontinuity approach to identify the dynamic treatment effects of bond authorization on local housing prices student achievement and district composition our results indicate that california school districts underinvest in school facilities passing a referendum causes immediate sizable increases in home prices implying a willingness to pay on the part of marginal homebuyers of 1 50 or more for each 1 of capital spending these effects do not appear to be driven by changes in the income or racial composition of homeowners and the impact on test scores appears to explain only a small portion of the total housing price effect c 2010 by the president and fellows of harvard college and the massachusetts institute of technology

taking prices seriously in the measurement of inequality abstract in the measurement of inequality adjustments for differences across households in their demographic composition and in the price regimes they face are usually very simple often nominal expenditure or income is adjusted with an expenditure independent price deflator and a price independent equivalence scale i show that using more flexible expenditure dependent price deflators and price dependent equivalence scales affects the level of and trend in measured family expenditure inequality in canada over 1969 1997 for example standard methods show a significant decrease in inequality between 1969 and 1978 but more flexible methods show a significant increase in inequality over this period

axiomatic foundations of hicksian measures of welfare change abstract the aggregate hicksian measures i ev i and i cv i are characterized by three simple properties one property concerns the ranking of two states the measures are paretian a second property expresses the postulate that welfare changes are to be evaluated in money the third one deals with redistributions of incomes distributional considerations are taken into account by employing variable distributional weights i

redistributive public employment abstract politicians may use disguised redistributive policies in order to circumvent opposition to explicit tax transfer schemes first we present a theoretical model that formalizes this hypothesis next we provide evidence consistent with the prediction of the model namely that in u s cities politicians use public employment as such a redistributive device we find that city employment is significantly higher in cities where income inequality and ethnic fragmentation are higher

the theory of reform and indian indirect taxes abstract given a set of value judgements an initial state and a model of the economy one can ask whether some feasible tax change would increase welfare we do this by defining the marginal cost in terms of welfare of raising an extra rupee from the i th good the inverse optimum problem is the calculation of non negative welfare weights on households which imply that the initial state is optimum if no such welfare weights exist then a pareto improvement is possible we illustrate the concepts and results using data from the indian economy for 1979 1980 directions of tax reform for a number of specific social welfare functions and for pareto improvements are presented

aggregate consumer behavior and the measurement of social welfare this paper describes a new approach to normative economics combining the theory of social choice with econometric modeling of aggregate consumer behavior we first derive a system of aggregate demand functions by exact aggregation over individual demand functions we then construct measures of individual welfare from systems of individual demand functions finally we incorporate these measures into a social welfare function introducing ethical assumptions based on horizontal and vertical equity to illustrate the application of this approach we consider the u s standard of living and its cost over the period 1947 1985 the purpose of this paper is to describe a remarkable convergence that has occurred between economic theory and econometrics over the past decade this conjunction has taken place between the theory of social choice and econometric modeling of aggregate consumer behavior the confluence of these two streams of research has produced a new approach to normative economics this approach has been successfully applied to the evaluation of economic policy the measurement of poverty and inequality and the assessment of the standard of living and its cost a common problem in the modeling of consumer behavior and social choice is the representation of individual preferences in the econometric modeling of aggregate consumer behavior the primary emphasis has been on simplifying aggregate demand functions the most familiar approach to this problem is the model of a representative consumer this model is required to justify applications of the theory of individual consumer behavior to aggregate data on prices and quantities consumed the simplest version of the model is based on identical homothetic preferences for all individuals under identical homothetic preferences aggregate quantities consumed are functions of aggregate expenditure and prices these functions have precisely the same properties as demand functions in the theory of individual consumer behavior the condition of identical homothetic preferences was weakened by gorman 1953 to permit displacements from the origin for individual demand functions gorman showed that a necessary and sufficient condition for aggregate demand functions to depend on aggregate expenditure is that all individu

taxation and the household abstract previous analyses of demand systems and the welfare effects of taxing male and female labour supplies suppress the analysis of household resource allocation by assuming a household utility function to analyse the implications of assuming this is not the case we construct a simple but fairly general model of household resource allocation and use the properties of the equilibrium of this model to characterise the effects of tax policy on individual utilities as determined by the household resource allocation process

the effects of region on the welfare and monetary income of spanish families in this paper we carry out a regional study aimed at measuring the effects of different regions on the welfare and income of spanish families this has in turn allowed us to calculate the inequality in welfare and income that exists between these households the results confirm the relation between welfare and monetary income for those spanish households in which both spouses work furthermore we find that the welfare level in the east and madrid regions is higher than elsewhere with the lowest welfare level being found in the south the comparison between regions allows us to rank them from the lowest to the highest welfare levels with this ranking adopting the order north centre east south and madrid

labour supply incentives and the taxation of family income taxing family income richard blundell and ian walker will lower marginal rates of income tax increase incentives to work the traditional theoretical argument ignores the fact that many individuals are members of households with more than one potential participant in paid employment the theory of optimal income tax is utilized to argue that the tax system should discriminate between individuals in the same household if their labour supply responses are different empirically the response of labour supply to changes in after tax wages is largest for secondary workers particularly married women hence the largest beneficial incentive effect is obtained if such individuals face lower tax rates since these individuals typically have below average pre tax earnings this suggests a simple way to implement our proposal establish a progressive income tax with individual earnings as the basis of assessment this might have additional advantages of fairness but its primary purpose would be to ensure that low earning but highly responsive individuals face low marginal tax rates while high earning but relatively unresponsive individuals face higher marginal tax rates contrary to popular wisdom a flat rate tax system would be less favourable for work incentives we illustrate this theoretical argument using an empirical model of labour supply embedded in a micro computer programme capable of simulating alternative tax systems

tax reform and housing demand the distribution of welfare gains and losses abstract we study distributional effects of a recent reform of the swedish system of income taxation which affects the price of owner occupied housing in calculating the welfare effects we account both for the non linearities of the income tax schedule and the dichotomous choice aspect of housing demand to own or to rent small and rosen 1981 have shown how the standard harberger type approximation formulae can be adapted to handle discrete choices and we modify their analysis for a non linear budget constraint

incentive regulatory policies the case of public transit systems in france we assess the empirical relevance of the new theory of regulation using a principal agent framework to study the regulatory schemes used in the french urban transport industry taking the current regulatory schemes as given the model of supply and demand provides estimates for the firms inefficiency the effort of managers and the cost of public funds it allows us to derive the first best and second best regulatory policies for each network and compare them with the actual situation in terms of welfare loss or gain fixed price policies lie between fully informed and uninformed second best schemes cost plus contracts are dominated by any type of second best contract from these results we may conjecture that fixed price contracts call for better informed regulators

reference price independent welfare prescriptions abstract a number of studies have evaluated the social welfare impact of price and income changes using equivalent incomes that are computed at some reference price vector and an aggregator with these equivalent incomes as arguments in place of a social welfare function this paper investigates the impact of the choice of the reference price vector on the results of such exercises distinguishing the case of individualized prices from the constrained case where all individuals face the same price vector we characterize preferences and aggregators leading to reference price independent welfare prescriptions

labor supply and targeting in poverty alleviation programs the introduction of variable labor supply raises some fundamental issues in analyzing the targeting of poverty alleviation programs in developing countries it forces a reconsideration of the standard objective function which is based on income or expenditure and so makes no allowance for the effort made in earning that income the authors show that alternative views on the appropriate valuation of effort have very different implications for commodity based targeting rules they also establish a benchmark for marginal effective tax rates inclusive of benefit withdrawal in income tested schemes and show that indicator targeting rules may also have to be modified significantly when labor supply responses are recognized

assessing indirect tax reform in a tourism dependent developing country summary the paper investigates the effects of reform of the current structure of indirect taxes in mauritius a relatively tourism dependent economy it uses a computable general equilibrium model to explore the relative efficiency of changing sales tax rates on tourism and nontourism related sectors and allowing for equity considerations the efficiency of tax reforms are also distinguished for cases where tourist arrivals are exogenously set and where they endogenously adjust to changes in relative prices the simulation results show that the tourism sectors are currently undertaxed additionally taxing tourism sectors is found to be the most socially efficient means of raising tax revenue

collective labor supply and welfare the paper develops a general collective model of household labor supply in which agents are characterized by their own possibly altruistic preferences and household decisions are only assumed to be pareto efficient an alternative interpretation is that there are two stages in the internal decision process agents first share nonlabor income according to some given sharing rule then each one optimally chooses his or her own labor supply and consumption this setting is shown to generate testable restrictions on labor supplies moreover the observation of labor supply behavior is sufficient for recovering individual preferences and the sharing rule up to a constant finally the traditional tools of welfare analysis can be adapted to the new setting

simulation of indirect tax reforms using pooled micro and macro french data this paper assesses the consequences of two reforms of the french indirect taxation system a vat harmonization which is close to initial ec proposals and a carbon tax which aims at decreasing the emissions of carbon dioxide we simulate the effects of tax reforms using estimates of a model of household expenditure behaviour estimation is obtained by using the property of perfect aggregation over households of the almost ideal demand system on pooled micro data from the 1978 1979 1984 1985 1989 issues of the french enquete budgets des familles combined with macro data from the quarterly national accounts from 1970 to 1990 simulations are conducted using a subsample of households from the 1989 consumer survey and generate useful results about the behavioural reactions to tax changes the impact on government revenue and the distributional effects of the reforms

the welfare cost of housing standards theory with application to jakarta abstract housing standards are likely to impose quantity constraints on the consumption possibilities of the poor this paper shows how an exact money metric of the welfare loss from such standards can be derived for any well behaved preference ordering recent results from the theory of consumer behavior under rationing permit the cost of standards to be interpreted in terms of the compensated demand function for the standardized good a housing demand function for the poor in jakarta is estimated using household level data and is used to calculate numerically the cost to them of introducing uniformly binding housing standards at unsubsidized prices estimates are also presented of the rate of price subsidy on housing needed for compensation

the measurement of horizontal inequality an alternative approach to the measurement of horizontal inequality is developed this measure of inequality is based on an explicit social welfare function which is formulated so as to be consistent with the basic principles of social choice the arguments of the social welfare function are welfare functions that depend on prices total expenditure and the demographic composition of the household the level of horizontal inequality is defined to be the difference between the level of social welfare attained at a perfect horizontally egalitarian distribution of welfare and the level of social welfare attained at the existing distribution of individual welfare the level of horizontal inequality induced by the introduction of commodity taxes is evaluated for the united states over the period 1947 85 copyright 1989 by mit press

estimating life cycle labor supply tax effects we present an econometrically tractable life cycle labor supply model for panel data including intertemporally progressive taxes on uncertai wage and nonwge incomes our two stage fixedeffects generalized method of moments approach first extimates intretemporal and then intertemporal preferences specification testing domonstrates the value of incorporating joint progressive taxation of labor and nonlabor incomes results for prime age men emphasize the roles played by hourly wage endogeneity worker specific effects the measure of the rate of pay and intemporal budget constaint nonseparability simulations indicate that recent tax reform while not self financing stimulated made labor supplied by about 3 percent and reduced deadweight loss about 16 percent

a computational procedure for calculating optimal commodity taxes with illustrative evidence from indian budget data a simple procedure for calculating optimal commodity taxes is proposed which takes into account the simultaneous interdependence of taxes expenditure and price levels responses the method also allows for the social marginal utility of income to depend on prices besides expenditures in a manner implied by the assumed preference functional form illustrative calculations on indian budget data provide evidence not only in favor of the procedure but of considerable sensitivity of directions of marginal tax reforms to the data set rural or urban used and of optimal tax estimates to demand functional form copyright 1989 by the editors of the scandinavian journal of economics

a pigovian rule for the optimum provision of public goods abstract the integrated treatment of optimal taxation and public expenditure presented here is based on the dual relationship between the prices of private goods and the quantities of public goods the conditions for optimum public good provision can be expressed as a modification of the samuelson conditions with extra terms representing a the distortionary effect of taxes on the willingness to pay for the public good and b distributional effects the former captures pigou s notion of the indirect damage caused by the need to finance public expenditure out of distortionary taxes and we call this the pigou term in certain cases a very simple benefit cost ratio for public projects emerges that is equivalent to measuring benefits as if they were taxed

measuring long term inequality of opportunity abstract in this paper we introduce a new family of rank dependent measures of inequality and social welfare consistent with the equality of opportunity eop principle the proposed framework can be used to measure long term as well as short term eop depending on whether we let permanent income or snapshots of income form the basis of the analysis furthermore it allows for both an ex ante and an ex post approach to eop there is long term ex post inequality of opportunity if individuals who exert the same effort have different permanent incomes in comparison the ex ante approach focuses on differences in the expected permanent income between groups of individuals with identical circumstances to demonstrate the empirical relevance of a long run perspective on eop we exploit a unique panel data from norway on individuals incomes over their working life span this allows us to examine how well analysis of opportunity inequality based on snapshots of income approximate the results based on permanent income

public export credit guarantees and foreign trade structure evidence from austria foreign trade is usually not based on cash transactions but rather sales on credit are the rule the resulting monitoring costs for lenders and the risk of default on accounts receivable are part of the costs associated with cross border goods transactions relative to domestic trade credit cross border credit creates trade barriers due to differences in language business practice jurisdiction and payment enforceability between trading partners export credit insurance has long been a domain of public export credit agencies only since the early 1980s private insurance is gaining ground using disaggregated panel data for goods exports from austria over the period 1996 to 2002 we show that public export credit guarantees have a less than proportional positive effect on international trade volume they predominantly affect the country structure of foreign trade but leave the industry specialisation almost unchanged

household equivalence scales and the measurement of inequality transfers from the poor to the rich could decrease inequality abstract the use of equivalence scales when measuring income inequality can lead to the paradoxical result that transferring money from poor to wealthy households may reduce measured inequality this paper explains this result and restates the pigou dalton transfer axiom in a way that gets around this counterintuitive outcome

urban rural cost of living differentials in a developing economy abstract casual observations suggest that the cost of living is substantially greater in urban than rural areas of developing economies with implications for sectoral welfare comparisons an aids demand model for housing and foodgrains is estimated on a household level data set for java after adjusting housing rents for heterogeneity in quality the retrieved cost function indicates that the cost of utility at the urban price vector exceeds its rural value although the differential has been substantially overestimated in the past the relative cost of urban living is found to increase as reference rural income increases

food subsidies and poverty alleviation this paper formulates the problem of the optimal pattern of food subsidies in a general setting where the objective is to minimize a class of poverty indices within the framework of the mo dern public finance theory taking explicit account of the budget con straint and preferences and technologies the authors derive rules fo r retargetting food subsidies to reduce poverty many operational rul es of thumb appear as special cases of the general results the analy sis thus provides not only the microfoundations of these operational rules but also their appropriate generalizations when the conditions under which they arise are not fulfilled copyright 1988 by royal economic society

the comparison of multi dimensioned distributions of economic status the literature on inequality measurement has been largely concerned with single dimensioned indicators this paper explores some of the issues which arise when there are several dimensions to inequality and these are not readily reduced to a single index concentrating particularly on the two dimensioned case we make use of results on multi variate stochastic dominance in portfolio theory extending these and applying them to the measurement of inequality the use of the dominance conditions is illustrated by an application to the international distribution of income and life expectancy

decomposition of s concentration curves for any given order of inverse stochastic dominance standard concentration curves are decomposed into three components called contribution curves those compo nents correspond to within group inequalities between group inequalities and transvari ational inequalities we prove for all orders that contribution curve dominance implies systematically welfare improving tax reforms and conversely accordingly as welfare ex pansions may be costly in terms of particular inequalities we propose targeted fiscal reforms jel classification d63 h20

first degree price discrimination goes to school personalized pricing is widely discussed but seldom observed making studies of its efficacy rare yet first degree price discrimination is common in the pricing of higher education and i use data on prices and the characteristics of students admitted to a professional graduate program at a public university to estimate a matriculation demand function i then derive linear pricing functions that maximize revenue for a target number of students by allowing these functions to depend on progressively richer sets of observables i explore the effect of personalization of pricing on profit tailoring prices to a one dimensional measure of student quality would raise revenue by 2 2 per cent above the revenue with uniform pricing pricing based on both student quality and state residency raises revenue by 8 4 per cent and further tailoring based on available observables raises prices 9 0 per cent above the maximum revenue under uniform pricing pricing that obeys current statutory tuition limits raises revenue less but still by just over half as much i also infer the welfare weights that the pricing process implicitly attaches to student characteristics

poverty dominant program reforms the role of targeting and allocation rules we propose simple graphical methods to identify poverty reducing marginal reforms of transfer programs the methods are based on program dominance curves that display cumulative program benefits weighted by powers of poverty gaps these curves can be decomposed simply as sums of targeting dominance curves and allocation dominance ones and can serve to verify whether the assessment of marginal program reforms is sensitive to the choice of poverty lines and poverty measures as well as to differences across programs in revenue sources and incentive effects

carbon taxation prices and welfare in new zealand abstract this paper examines the effects on consumer prices arising from imposing a carbon tax in new zealand using information about inter industry transactions and the use of fossil fuels by industries the welfare effects of the carbon tax are examined for a range of different household types finally overall measures of inequality are reported

the measurement of deadweight loss revisited modities such as various consumer goods and labor m fixed factors such as land natural resources and various types of fixed capital and a government which taxes commodities and fixed factors in order to finance various govern ment expenditures it is well known2 that if the government can raise its required revenue by taxing the fixed factors alone then the resulting allocation of resources is pareto optimal no single household s utility or real income can be increased without decreasing the utility of some other household suppose we are at an initial equilibrium where government revenue is being raised by taxing the fixed factors alone then the resulting equilibrium can be rationalized by maximizing a certain weighted sum of utility functions subject to various feasibility constraints now think of the government replacing the taxes on fixed factors with distortionary commodity taxes in section 3 we calculate the second order directional derivative of the above weighted sum of utility functions with respect to any feasible direction of tax change evaluated at the initial equilibrium which is pareto optimal of course the first order directional derivatives of the weighted sum of utility functions with respect to feasible directions of tax change are zero evaluated at this initial equilibrium we obtain a measure of economic loss due to tax distortions which is virtually identical to that of boiteux 3 p 113 and which bears a resemblance to the dead loss of hotelling 22 p 254 the consumer s surplus measures of hicks 19 20 pp 330 3 and the deadweight loss measure of harberger 16 p 61 17 p 788 in section 4 we calculate a measure of welfare loss based on debreu s 4 5 coefficient of resource utilization which is a modification of a measure of loss due to allais 1 2 and we show that under certain conditions the hotelling

can carbon taxes be progressive abstract most studies have assessed the distributional impact of carbon taxes through their effects on commodity prices alone while ignoring their impact on individual welfare brought about by changes in factor prices yet the remunerations of capital and labor are not affected by these taxes similarly and their shares in earned incomes are not uniform across households this paper provides a comprehensive analysis of the incidence of carbon taxes on inequality by considering simultaneously the commodity and the income channels we propose a decomposition of the change in individual welfare metrics then we develop a general equilibrium model to assess the impact of carbon taxes on factor and commodity prices and subsequently their distributional impact on households using the lorenz and concentration curves and the gini index our results suggest that changes in factor prices and changes in commodity prices especially those of energy commodities have opposing effects on inequality carbon taxes tend to reduce inequality through the changes in factor prices and tend to increase inequality through the changes in commodity prices hence we find a non monotonic u shaped relationship between carbon taxes and inequality our results suggest that the traditional approach of assessing the impact of carbon taxes on inequality through changes in commodity prices alone may be misleading the findings cast light on the desirability of using both channels in the assessment of carbon taxes on inequality

towards a household model of uk domestic energy demand abstract most existing analyses of domestic energy demand in the uk are conducted at the aggregate level the paper argues the case for modelling at the level of the individual household some results are presented from a microeconometric model estimated using microdata on some 90 000 uk households separate equations are estimated for gas demand electricity demand for households with a gas supply and electricity demand for those without price and income elasticities are presented these show considerable variation with household characteristics

equity and efficiency consequences of unemployment insurance reform in canada the importance of sensitivity analyses this paper conducts an evaluation of the equity and efficiency consequences of proposals for the reform of the canadian unemployment insurance program the sensitivity of results to the measure of welfare chosen and to the model employed to simulate individual behavioral responses is illustrated copyright 1991 by the london school of economics and political science

equity and policy effectiveness with imperfect targeting abstract we propose a general approach that jointly integrates horizontal and vertical equity criteria in the assessment of poverty alleviation programs with the strength of each criterion being captured through its own inequity aversion parameter this contrasts with the assessment of poverty alleviation programs done with simple under coverage and leakage ratios or with other methods that do not take into account the heterogeneity of the poor and that do not address directly the social benefits of achieving normative criteria our methodology is illustrated using tunisian data and two alternative poverty alleviation policies we find inter alia that the social ranking of commodity and socio demographic targeting in tunisia depends on the policymaker s comparative preference for vertical and horizontal equity

the dynamic efficiency cost of not taxing housing traditional welfare cost estimates of tax subsidies for owner occupied housing are less than 0 5 of gnp in the united states and canada this paper argues that these static measures understate the true cost of the tax subsidy increasing the capital income tax makes untaxed housing more valuable delivering a windfall bonus to existing homeowners at the expense of future generations this intergenerational transfer has real efficiency effects in the presence of pre existing tax distortions when housing is in fixed supply the dynamic efficiency cost of preferential tax treatment for housing is as much as 2 2 of gnp or 120 billion dollars in 1990

public economics yesterday today and tomorrow public economics that is to say the study of public intervention in the economy 1 has emerged from public finance in the 1950s to reach its autonomy at the beginning of the seventies with in particular the creation of the journal of public economics in 1971 with some oversimplifications we are going to argue that modern public economics was born from taking into account more or less explicitly the informational constraints of the state in its role of production allocation and distribution of resources the criticism of the benevolent state by the virginia polytechnic institute and chicago schools followed today by a renewal of political economy constitutes the second major key to read the new developments of public economics this leads us to a presentation in four parts section 2 will overview the implications of the arrow debreu general equilibrium paradigm in public economics section 3 will present some essential results obtained in public economics when the informational constraints of the state are taken into account the paradigm of the benevolent state will be criticized in section 4 section 5 will briefly sketch our view of the immediate future for public economics

anatomy of poverty during adjustment the case of the philippines recent discussions of development policy have emphasized the need for macroeconomic adjustment programs that give attention to poverty and social concerns conventional adjustment programs applied in developing countries are considered to have no human face as they focus almost exclusively on promoting economic efficiency and bringing an economy to a stable and sustainable growth path in particular observers have claimed that the poor have disproportionately borne the pain of transitional costs of adjustment especially when the transition has been longer than initially expected indeed increases in poverty as well as sharp cuts in government expenditures on social services including health nutrition education and infrastructure programs benefiting the poor have accompanied the implementation of adjustment policies in a number of less developed countries ldcs on the other hand country cases where the transition apparently has not been antipoor even in the short run also exist indonesia s experience with adjustment in the 1980s for example appears to be one such case 2 in general the available evidence indicates that changes in living conditions in the short run do not appear to be systematically related to the presence or absence of adjustment programs 3 the lack or the poor quality of data especially on social and human development indicators in ldcs hampers the analysis of the link between adjustment policies and poverty alleviation moreover because the transition in many countries is an ongoing process the impact of the adjustment is still in the making thus available information gives only a partial and possibly even misleading picture of the full effects of adjustment policies on the poor s standard of living even when reliable data are available the analysis has to move beyond simple correlations and establish counterfactual situations specifi

international comparisons of living standards by equivalent incomes we propose a measure of living standards for international comparisons based on gdp per capita the measure incorporates corrections for international flows of income labor risk of unemployment healthy life expectancy household demography and inequalities the method for comparing populations that differ in some non income dimension consists of computing the equivalent variation of income that would make each population indifferent between its current situation and a reference situation with respect to the non income dimension this is applied to 24 oecd countries the obtained ranking of countries differs substantially from the gdp ranking

the efficiency of local government the role of privatization and public sector unions abstract local governments spend roughly 1 6 trillion per year to provide a variety of public services ranging from police and fire protection to public schools and public transit however we know little about public sector s productivity in delivering key services public bus service represents a standardized output for benchmarking the cost of local government service provision among the top twenty largest cities there exists significant dispersion in the operating cost per bus mile with the highest being more than three times as high as the lowest using a regression discontinuity design we estimate the cost savings from privatization and explore the political economy of why privatization rates are lower in high cost unionized areas our analysis suggests that fully privatizing all bus transit would generate cost savings of approximately 5 7 billion or 30 of total u s bus transit operating expenses the corresponding increased use of public transit from this cost reduction would lead to a gain in social welfare of 524 million at minimum and at least 26 000 additional transit jobs
