welfare dominance an application to commodity taxation in this paper the authors propose a method to identify commodity tax changes that will be favored by all individuals who can agree on certain weak assumptions with regard to the social welfare function the method is based on an extension of the criterion of second degree stochastic dominance and is illustrated using data from israel copyright 1991 by american economic association

on measures of excess burden and their application abstract new measures of the additional excess burden of a tax reform are proposed and are shown to be useful in three key policy applications these new measures induce a unique measure of marginal excess burden meb among its interesting properties meb is uniformly zero for a proportional tax on inelastically supplied labor problems in applying the standard measures of total excess burden are demonstrated it is concluded that the induced measure of the marginal cost of funds mcf should be regarded as the most useful concept in applied tax analysis

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

international comparisons of welfare and poverty dominance orderings for ten countries inference based stochastic dominance procedures are applied to luxembourg income study data to rank ten western countries in terms of standards of living and poverty first order dominance comparisons ranks more than 50 percent of all pairwise comparisons and second order generalized lorenz dominance adds another 25 percent truncated dominance analysis is used to make inferences about poverty and up to 98 percent of the truncated distributions are ordered the results differ substantially from those obtained when only relative incomes and inequality are considered

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

when different market concentration indices agree abstract the herfindahl hirschman entropy and n firm indices may not agree when comparing market concentrations for different oligopoly markets the majorization pre ordering is shown to be both necessary and sufficient for all to agree

the impossibility of a progressive tax structure abstract when households are identical in all respects other than income a non decreasing average tax rate is both necessary and sufficient for post tax incomes to be always at least as equal as pre tax incomes this paper investigates whether this well known result can be extended to households with different needs a tax structure which never increases inequality in the lorenz sense is shown to be unable to discriminate between household types if in addition the tax structure never reduces the relative income of the poorest member of the neediest group of households then the same proportional tax must be applied to all households and redistribution is impossible either within or between groups of households with differing needs a similar conclusion is reached using conventional equivalence scale arguments and also applies when the parameters of the tax schedules are determined endogenously we discuss the significance of this impossibility result and its implications for tax design

an asset allocation puzzle comment the purpose of this note is to look at the rationale behind popular advice on portfolio allocation among cash bonds and stocks we argue that the typical investment advice is not inconsistent with the behavior of risk averse expected utility maximizers we propose an additional solution to the asset allocation puzzle posed by niko canner et al 1997 who argue that popular advice contradicts financial theory because it is inconsistent with the capital asset pricing model capm mutual fund separation theorem the capm asserts that investors should hold the same selection of risky assets while popular advice is that investors should hold a proportion of bonds to stocks that increases with risk aversion using mean variance mv analysis and the capm canner et al show that recommended portfolios are far from optimal and that losses from the apparent failure of optimization are not substantial however they failed to explain the popular advice within an economic model we offer a rational model based on stochastic dominance to demonstrate that all popular financial advice portfolios belong to the efficient set for all risk averse investors using the historical annual real returns on bonds and stocks in canner et al we cannot ascertain that investment advisors indeed offer bad advice rather we maintain that acting as agents for numerous clients advisors recommend portfolios that are not inefficient for all risk averse investors i overview

rank dominance and international comparisons of income distributions abstract the rank dominance criterion for comparing income distributions assumes the pareto principle anonymity and population size invariance this paper applies rank dominance to compare international income distributions empirically rank dominance is a powerful tool for ordering income distributions our results suggest that much of the power of generalized lorenz dominance is due to efficiency preference and equity preference adds only marginally to the ability to order income distributions

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

what is this school called neoclassical economics what is this school called neoclassical economics does it exist should it where does the term neoclassical economics come from and is there any connection between any of the current interpretations of the term and its original meaning how do we make sense of competing current interpretations is there a sustainable formulation these and related questions are raised and answered in an attempt to bring clarity to ongoing economic discussion and debate thereby to under labour for a more relevant academic economics discipline

mainstream economic methodology what might reasonably be expected of a survey of mainstream economic methodology would be a statement as to the nature and role of methodology and a discussion of how it impinged on economic practice however the mainstream understanding of the nature and role of methodology has been in a state of transition further mainstream economics has evolved virtually independently of explicit methodological analysis nevertheless the outcome of current thinking among methodologists could well be the development of a closer bond between methodology and practice theorists too are contemplating potentially profound methodological changes this is therefore a particularly good time to take stock and identify the direction of change and its implications for the future of mainstream economics 1

the impact of food stamps on us poverty in the 1980s a marginal dominance analysis the relative effectiveness of the us food stamp program in reducing the incidence and depth of poverty is compared at a number of poverty lines across time the analysis is based upon an extension of dominance methods for ordering poverty recently developed statistical inference procedures and a merged data set that permnits an unusually comprehensive measure of income the comparative effectiveness of the food stamp program in reducing headcount poverty over time is contingent on the poverty line selected however the reduction in poverty gaps is greater in 1990 than in 1982 regardless of the poverty line chosen the sensitivity of the results to the income concept equivalence scale and time period used for measuring income are also considered

what s in a name tony lawson on neoclassical economics and heterodox economics in this article i respond to tony lawson s what is this school called neoclassical economics lawson s paper is provocative because it reformulates neoclassical economics based on veblen s original intent as a mismatch created by recognising the value of an evolutionary approach to the economy whilst remaining over reliant on elements of a taxonomic approach for lawson many heterodox economists may be neoclassical under this description i argue that there is clearly a case to be heard but that the reformulation of the neoclassical raises a number of issues there are issues concerning the specific critique of the current usage of the term neoclassical regarding genealogy and meaning there are specific issues regarding the further development of the new old veblen definition of the neoclassical how clear is the definition in a practical context as a way to identify a neoclassical group based on the commitments of the critique and the definition what does it mean to be more realistic and what is the strategic value of such a provocation for heterodoxy i argue that the combination of these are reasons for more consideration of issues of social ontology not less insofar as the terms of the argument are incomplete and this invites both lawson and those he is criticising to progress the argument particularly on method

an economic assessment of the common market organization for bananas in the european union abstract the main objective of this paper is to provide some estimates of how the world banana market has been affected by the common market organization cmo for bananas established in the european union eu on 1 july 1993 and modified in april 1994 we quantify the effects of the new eu regulation on world and eu prices on the structure of eu imports from latin american countries african caribbean and pacific acp countries and eu regional suppliers on the pattern of consumption in the various eu member states and on consumers and producers welfare using a static partial equilibrium model of the world banana market simulation results suggest that the two key variables in determining the effects of the cmo are the size of the tariff quota on dollar and non traditional acp bananas and the capacity of acp countries to exhaust their acp contingent share

guidelines on searching for a dalton improving tax reform this article documents the search for a dalton improving tax and expenditure reform using a methodology developed by yitzhaki and slemrod 1991 and mayshar and yitzhaki 1995 the methodology overcomes the need to define a specific social welfare function by searching instead for reforms that improve each social welfare function belonging to a wide class of functions the authors apply the method to the energy sector of indonesia ignoring distributional constraints and find that both the subsidy on kerosene and the tax on gasoline should be reduced but taking distributional concerns into account the present structure of energy taxes is reasonable and the country may benefit by increasing the subsidy to kerosene taxing electricity and reducing the gasoline tax these conclusions are robust to changes in the relevant parameters representing the indonesian economy

the measurement of inequality and poverty a policy maker s guide to the literature abstract mathematical measures of poverty and inequality embody values that reflect the historical political social intellectual and ethical forces prevalent at the time of their formulation so that policy makers may select measures of poverty and inequality that are consistent with their values it is important to make explicit the value judgements implicit in the measures models designed to measure poverty and inequality fall into four categories absolute poverty measures absolute income measures relative poverty measures and relative inequality measures this article examines the principal models within each category and discusses the assumptions limitations and values implicit in the models

testing for marginal changes in income distributions with lorenz and concentration curves asymptotically distribution free statistical tests for comparing absolute and relative lorenz and concentration curves are provided the procedures do not require independent samples and can be used to test for marginal changes in income distributions the tests are illustrated using a large sample of tax returns that have been randomly selected for audit by the internal revenue service the tests reveal the marginal effects of systematic underreporting of income and tax liabilities on the u s income distribution copyright 1994 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

almost marginal conditional stochastic dominance marginal conditional stochastic dominance mcsd developed by shalit and yitzhaki 1994 gives the conditions under which all risk averse individuals prefer to increase the share of one risky asset over another in a given portfolio in this paper we extend this concept to provide conditions under which most and not all risk averse investors behave in this way instead of stochastic dominance rules almost stochastic dominance is used to assess the superiority of one asset over another in a given portfolio switching from mcsd to almost mcsd amcsd helps to reconcile common practices in asset allocation and the decision rules supporting stochastic dominance relations a financial application is further provided to demonstrate that using amcsd can indeed improve investment efficiency

ranking income distributions a large variety of policy questions involve choices between social states and a consequent ordering of the feasible alternatives when these social states are related to the levels of welfare experienced by individuals or households two central issues stand out in determining the relative desirability of different social outcomes one of these is the essentially positive exercise of achieving comparability between households with different characteristics such as composition or preferences operating in different environments for example facing different price structures the other concerns the normative judgments implicit in the evaluation of alternative allocations of resourcesthe emphasis placed on inequality between households and the extent to which greater inequality can be compensated by higher average living standards this paper focuses on the second of these issues and in doing so we abstract from the problem of household comparability by considering a population of n households identical in all respects except for their incomes the question of ordering social states then becomes one of ranking income distributions over a group of anonymous households or individuals borrowing the usual assumptions imposed on consumer preferences we may suppose that a social ordering of income distributions can be represented by a welfare function 2

ethically robust comparisons of bidimensional distributions with an ordinal attribute abstract we provide foundations for robust normative evaluation of distributions of two attributes one of which is cardinally measurable and transferable between individuals and the other is ordinal and non transferable the result that we establish takes the form of an analogue to the standard hardy littlewood polya theorem for distributions of one cardinal attribute more specifically we identify the transformations of the distributions which guarantee that social welfare increases according to utilitarian unanimity provided that the utility function is concave in the cardinal attribute and that its marginal utility with respect to the same attribute is non increasing in the ordinal attribute we establish that this unanimity ranking of the distributions is equivalent to the ordered poverty gap quasi ordering introduced by bourguignon 12 finally we show that if one distribution dominates another according to the ordered poverty gap criterion then the former can be derived from the latter by means of an appropriate and finite sequence of such transformations

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

uncovering regulator s implicit social welfare weights under price cap regulation abstract this paper provides a simple procedure that can be used in empirical works aimed at uncovering the preferences of regulators over consumers the inverting procedure proposed by ross 1984 ross t w 1984 uncovering regulator s social welfare weights rand journal of economics 15 152 155 is adapted to a regulatory situation characterised by price cap regulation

the absence of deprivation as a measure of social well being an empirical investigation abstract the generalised lorenz criterion is widely used for making welfare comparisons within and across countries on the basis of their income distributions experimental studies have challenged this way of proceeding by showing that the principle of transfers which underlies the generalised lorenz criterion does not meet with widespread agreement among the public that theorists would have expected we propose to substitute the non deprivation quasi ordering introduced by chakravarty 1997 for the generalised lorenz criterion this criterion is less demanding than the generalised lorenz criterion as it builds on a weaker version of the principle of transfers and it is therefore more likely to be accepted by the public we use income data from the luxembourg income study for 17 countries in order to contrast the generalised lorenz and the non deprivation criteria although the non deprivation quasi ordering is less decisive than the generalised lorenz criterion it is shown that the former approximates the latter surprisingly well

communal property and land markets agricultural development policy in st lucia abstract communal land tenure in st lucia was targeted for privatization in 1986 on the premise that its undercapitalization and low productivity could be corrected by establishing an efficient land market this article takes the neoclassical analysis which was used to support this policy to task with empirical evidence from st lucia it argues that the inefficiencies attributed to communal land only are not justified many of these inefficiencies are in fact also shared with freehold tenure in addition family land performs socioeconomic functions that cannot be achieved with freehold tenure and fulfills a critical function in the development process

empirical application of optimal commodity tax theory to taxation of alcoholic beverages this paper concerns the calculation of optimal taxes on commodities which contain a common externality generating component the first best solution is characterized by a form of marginal cost pricing with production costs increased according to the harm content of commodities valued at marginal external cost an application to finnish alcohol consumption data is made to indicate how the tradeoff between control and revenue requirements affects taxes by bootstrapping the estimates taxes are found to be less sensitive than compensated elasticities

applied economics contrast explanation and asymmetric information the purpose of this paper is to illustrate the workings of an explanatory method for applied economics it is a method that is rarely explicitly examined or defended in the discipline but which i believe has a lot of promise for the sorts of contexts that economists must address my strategy is to show that and how the method in question effectively underpins at least one study already widely regarded as explanatorily successful copyright the author 2008 published by oxford university press on behalf of the cambridge political economy society all rights reserved oxford university press

the asset allocation puzzle is still a puzzle abstract intertemporal hedging activity has been advocated as being the solution to the asset allocation puzzle a standing assumption made in the dynamic asset allocation literature is that one or several bonds can perfectly hedge the interest rate risk and related market price of risk in the economy in a multi asset world ceteris paribus such an assumption biases the portfolio allocation of a non myopic investor towards bonds we extend the literature to allow for an incomplete bond market when solving for the optimal portfolio choice of a rational investor it is shown that investors with a high level of risk aversion could invest more in stocks than in bonds

testing the significance of income distribution changes over the 1980s business cycle a cross national comparison using kernel density estimation we describe the distribution of household size adjusted real income and how it changed over the business cycle of the 1980s in the united states and the united kingdom we confirm previous studies that show income inequality increased in the two countries and the middle of the distribution was squashed down using a series of statistical tests however we find that while the mass in both tails of the distribution increased significantly in both countries over the period by far the greatest gains were in the upper tail copyright 1999 john wiley sons ltd

on the rank generalized lorenz and overtaking criteria for evaluating stochastic income regimes this essay is concerned with the evaluation of income regimes that is a set of income classes and the stochastic process which governs the individual s position among the income classes we follow champernowne 4 theil 21 shorrocks 18 19 bartholomew 2 geweke marshall and zarkin 9 and conlisk 5 in characterizing mobility as a markov chain here states of a markov chain correspond to positions in the income classes utilizing the ergodic theorem for markov chains and propositions from the theory of decisionmaking under uncertainty we derive necessary and sufficient conditions on the income classes for one such income regime to be preferred to another in terms of the overtaking criterion specifically we show that the rank dominance condition saposnik 17 is necessary and sufficient for there to be a critical time at which overtaking occurs for each agent this time depends on the agent s von neumann morgenstern utility function which is merely required to be monotone increasing in income moreover versions of the generalized lorenz criterion shorrocks 20 provide necessary and sufficient conditions for there to be a time at which uniform overtaking occurs this time being the same for all agents provided the agents are risk averse among the applications of this model to individual choice one may consider a new college graduate deciding among employment opportunities in addition to starting salaries an applicant should consider the firms entire salary schedules as well as prospects for promotion within each firm alternatively one may consider a musician who must choose between a back section position with a leading orchestra or a more prominent position with a less highly regarded orchestra again one may be wise to consider the entire compensation schedule as well as the prospects for

aversion to health inequalities in healthcare prioritisation a multicriteria optimisation perspective abstract in this paper we discuss the prioritisation of healthcare projects where there is a concern about health inequalities but the decision maker is reluctant to make explicit quantitative value judgements and the data systems only allow the measurement of health at an aggregate level our analysis begins with a standard welfare economic model of healthcare resource allocation we show how under the assumption that the healthcare projects under consideration have a small impact on individual health the problem can be reformulated as one of finding a particular subset of the class of efficient solutions to an implied multicriteria optimisation problem algorithms for finding such solutions are readily available and we demonstrate our approach through a worked example of treatment for clinical depression

relative undernutrition in puerto rico under alternative food assistance programmes in the early 1980s puerto rico experienced a conversion from the food stamp program fsp to the nutrition assistance program nap and a severe recession to compare relative undernutrition in puerto rico in 1977 and 1984 stochastic dominance methods and statistical inference procedures are applied to nutrient distributions to separate the effect of the recession from the effect of converting food coupons to cash benefits a multiple regression model of nutrient consumption is also estimated in the dominance comparisons every improvement in nutrition status between 1977 and 1984 is statistically significant at the lowest quintile while no case of worsening undernutrition is significant at the lowest quintile the multiple regression model provides some evidence that the conversion from food coupons to cash might have reduced nutrition status in the lowest quintile but a larger proportion of food assistance was allocated to low income households under the nap than under the fsp no evidence of signi

an asset allocation puzzle this paper examines popular advice on portfolio allocation among cash bonds and stocks it documents that this advice is inconsistent with the mutual fund separation theorem which states that all investors should hold the same composition of risky assets in contrast to the theorem popular advisors recommend that aggressive investors hold a lower ratio of bonds to stocks than conservative investors the paper explores various possible explanations of this puzzle and finds them unsatisfactory copyright 1997 by american economic association

economics as progress the lse approach to econometric modelling and critical realism as programmes for research in the face of claims that economics is increasingly driven merely by fashion this paper draws out certain similarities and differences between two self consciously progressive and developmental research programmes namely the lse approach to econometric modelling and critical realism in economics the argument is that while these two programmes of research share a common point of departure and possess many common elements what at root distinguishes them is their adoption of opposing philosophical orientations the comparison enables both the nature of each programme and the relevance of their common concerns to be more easily appreciated and helps clarify the sort of evidence that would provide a basis for selecting one project over the other copyright 2005 oxford university press

multidimensional welfare distributions empirical application to household panel data from vietnam this article explores the empirical application of theoretical multidimensional welfare distribution analysis techniques to real household welfare distributions the article operationalizes recent conceptual developments in multidimensional distribution theory and assesses their usefulness for the measurement of multidimensional household inequality the results strongly highlight the importance of bringing nonmonetary aspects of household welfare into the forefront of inequality analysis agreement over the various approaches to the measurement of multidimensional inequality entails however nontrivial decisions that may limit the practical usefulness of these measures we suggest that the use of multidimensional inequality ranges and the application of restrictive dominance criteria to multidimensional welfare distributions may open significant scope for further developments in the empirical analysis of multidimensional inequality

dalton improving tax reform when households differ in ability and needs abstract in a previous paper we suggested a method for identifying tax reforms that adhere to dalton s principle of transfers approving a small enough transfer from rich to poor however even the weak requirement from that method namely prescribing a uni dimensional ordinal ranking of households by how deserving they are of a marginal income transfer is con fining here we extend the approach by formulating a two dimensional criterion for a dalton improving tax reform when there is social approval for transfers when other things are equal from the more able to the less able and from less needy households to more needy ones the possibility of applying this extended criterion in practice and a comparison with other criteria is carried out using the example of u k excise taxes

a unified framework for pro poor growth analysis starting with a general impact indicator as an evaluation criterion the author offers an integrative framework for a unified discussion of various concepts and measures of pro poor growth emerging from the current literature he shows that whether economic growth is considered pro poor depends fundamentally on the choice of evaluative weights in addition the author s framework leads to a new indicator of the rate of pro poor growth that can be interpreted as the equally distributed equivalent growth rate this is a distribution adjusted rate of growth that depends on the chosen level of inequality aversion illustrations based on data for indonesia in the 1990s show a strong link between growth and poverty reduction in that country a decomposition of the observed poverty outcomes reveals the extent to which changes in inequality have blunted the poverty impacts of both growth and contraction finally the results also demonstrate that absolute and relative indicators of pro poor growth can lead to conflicting conclusions from the same set of facts

lorenz dominance and welfare changes in the u s distribution of income 1967 1986 this paper examines income inequality in the untied states over the period 1967 86 using recently developed tests for differences in lorenz curves the authors are able to rank eighteen of nineteen annual comparisons in contrast standard techniques are able to rank only twelve these results suggest that the lorenz dominance principle is more empirically relevant than previously thought the tests reveal a sharp rise in u s inequality between 1978 and 1982 as well as a shift toward greater inequality over the entire period the authors also examine changes in economic welfare using the joint mean lorenz dominance principle copyright 1991 by mit press

economic history and economics i have in the back of my mind a picture of the sort of discipline economics ought to be or at least the sort of discipline i wish it were if economics were practiced in that way there would be nothing problematical about its reciprocal relationship with economic history it would be pretty clear what it is that economic theory offers to economic history and what economic history offers to economic theory i will try to describe what i mean below for better or worse however economics has gone down a different path not the one i have in mind one consequence not the most important one but the one that matters for this discussion is that economic theory learns nothing from economic history and economic history is as much corrupted as enriched by economic theory i will come to that too later on you will notice that i am using strong language i am prepared to admit right away that i may be dead wrong in my judgements but there is no point in pussyfooting bluntness may lead to an interesting discussion after all no one would remember the old german historical school if it were not for the famous methodenstreit actually no one remembers them anyway there must be a lesson in that to get right down to it i suspect that the attempt to construct economics as an axiomatically based hard science is doomed to fail there are many partially overlapping reasons for believing this but since that is not the topic under discussion today i do not have to lay them out in an orderly way i hope the following hodgepodge will convey what i mean a modern economy is a very complicated system since we cannot conduct controlled experiments on its smaller parts or even observe them in isolation the classical hardscience devices for discriminating between competing hypotheses are closed to us the main alternative device is the statistical analysis of historical time series but then another difficulty arises the competing hypotheses are themselves complex and subtle we know before we start that all of them or at least many of them are capable of fitting the data in a gross sort of way then in order to make more refined distinctions we need long time series observed under stationary conditions unfortunately however economics is a social science it is subject to damon runyon s law that nothing between human beings is more than three to one to express the point more formally much of what we observe cannot be treated as the realization of a stationary stochastic process without straining credulity moreover all narrowly economic activity is embedded in a web of social institutions customs beliefs and attitudes concrete outcomes are indubitably affected by these background factors some of which change slowly and gradually others erratically as soon as time series get long enough to offer hope of discriminating among complex hypotheses the likelihood that they remain stationary dwindles away and the noise level gets correspondingly high under these circumstances a little cleverness and persistence can get you almost any result you want i think that is why so few econometricians have ever been forced by the facts to abandon a firmly held belief indeed some of fortune s favorites have been known to write scores of empirical articles without once feeling obliged to report a result that contradicts their prior prejudices if i am anywhere near right about this the interests of scientific economics would be better served by a more modest approach there is enough for us to do without pretending to a degree of completeness and department of economics massachusetts institute of technology cambridge ma 02139

statistical inference for the measurement of the incidence of taxes and transfers we establish the asymptotic sampling distribution of general functions of quantile based estimators computed from samples that are not necessarily independent the results provide the statistical framework within which to assess the progressivity of taxes and benefits their horizontal inequity and the change in the inequality of income which they cause by the same token these findings characterise the sampling distribution of a number of popular indices of progressivity horizontal inequity and redistribution they can also be used to assess welfare and inequality changes using panel data and to assess poverty when it depends on estimated population quantiles we illustrate these results using micro data on the incidence of taxes and benefits in canada

sharing the cost of a public good an incentive constrained axiomatic approach we study the problem of provision and cost sharing of a public good in large economies where exclusion complete or partial is possible we search for incentive constrained efficient allocation rules that display fairness properties population monotonicity says that an increase in population should not be detrimental to anyone demand monotonicity states that an increase in the demand for the public good in the sense of a first order stochastic dominance shift in the distribution of preferences should not be detrimental to any agent whose preferences remain unchanged under suitable domain restrictions we give an explicit characterization of all incentive constrained efficient allocation rules we then show that there exists a unique incentive constrained efficient and demand monotonic allocation rule the so called serial rule in the binary public good case the serial rule is also the only incentive constrained efficient and population monotonic rule

the effects of rising food prices on poverty in mexico we evaluate the impact of the rise in food prices during 2006 2008 on the poverty and extreme poverty rates in mexico we concentrate on the poor s consumption of staple foods and analyze the change in their consumption brought about by changed prices we also allow households receiving income from the farming and livestock sector to benefit from increases in prices of food products we find a modest increase in poverty using 2006 2007 prices however there is a daunting effect on the poor once the 2008 prices are taken into account after considering the positive effects of public policies announced in 2008 such as reduced taxes and tariffs on food products and greater subsidies to the extremely poor the poverty rate measured through consumption increases from 25 to 33 5 and the extreme poverty rate from 10 58 to 16 given the increase in food prices further analysis using the theory of optimal taxes suggests policies oriented towards relieving the food price pressure on the mexican poor should aim at lowering the prices of eggs vegetable oil milk and chicken

the measurement and trend of housing inequality in the united states 1978 85 inequality in housing services for renters owners and all households in the united states is estimated for 1978 and 1985 hedonic techniques are applied to data from the american housing survey to derive values for housing services that include publicly provided as well as subsidized housing we find significant disparities in housing but substantially less inequality than in incomes in 1978 the top decile garnered 19 2 of housing services while the bottom decile received only 5 1 the trend however is towards greater equality in housing with large and statistically significant shifts across all deciles by 1985 the share of the top decile dropped to 16 3 a percentage decrease in share of 15 3 while that of the bottom decile rose to 5 7 a percentage increase of 11 4

analysis of the distributional impact of out of pocket health payments evidence from a public health insurance program for the poor in mexico many governments have health programs focused on improving health among the poor and these have an impact on out of pocket health payments made by individuals therefore one of the objectives of these programs is to reach the poorest and reduce their out of pocket expenditure in this paper we propose the distributional poverty impact approach to measure the poverty impact of out of pocket health payments of different health financing policies this approach is comparable to the impoverishment methodology proposed by wagstaff and van doorslaer 2003 that compares poverty indices before and after out of pocket health payments in order to escape the specification of a particular poverty index we use the marginal dominance approach that uses non intersecting curves and can rank poverty reducing health financing policies we present an empirical application of the out of pocket health payments for an innovative social financing policy implemented in mexico named seguro popular the paper finds evidence that seguro popular program has a better distributional poverty impact when families face illness when compared to other poverty reducing policies the empirical dominance approach uses data from mexico in 2006 and considers international poverty standards of 2 per person per day

bonds versus stocks investors age and risk taking abstract it has become increasingly popular to advise investors to relocate their funds from a primarily stock portfolio to a primarily bond portfolio as they get older however the well known decision rules such as mean variance or stochastic dominance rules are unable to explain this common practice almost stochastic dominance asd and almost mean variance amv approaches are used to examine the dominance of stock and bond portfolios asd and amv rules unambiguously support the popular practice of advising higher stock to bond ratio for long investment horizons hence we provide an explanation to the practitioners recommendation within the expected utility paradigm

nutrition and nonparticipation in the us food stamp programme microdata from the national food consumption survey are used to test for differences in caloric and protein intake distributions we compare poor households that participate in the us food stamp programme to eligible households that do not participate tests for stochastic dominance provide unambiguous evidence that eligible nonparticipants suffer from relative undernutrition compared to participating households probit analysis is used to identify characteristics of participating and nonparticipating households

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

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

income distribution in the dynamic two factor trade model the issue of the effects of trade on personal income distribution has remained largely unexamined this paper describes an overlapping generations 2 x 2 model with a bequest motive and heterogeneous agents in order to examine the problem in this dynamic setting trade leads to both short run and long run reductions increases in inequality in labor capital abundant countries if the investment good is capital intensive if the consumption good is capital intensive the short run effects continue to hold but the long run effects are ambiguous copyright 1992 by the london school of economics and political science

guidelines on searching for a dalton improving tax reform an illustration with data from indonesia this article documents the search for a dalton improving tax and expenditure reform using a methodology developed by yitzhaki and slemrod 1991 and mayshar and yitzhaki 1995 the methodology overcomes the need to define a specific social welfare function by searching instead for reforms that improve each social welfare function belonging to a wide class of functions the authors apply the method to the energy sector of indonesia ignoring distributional constraints and find that both the subsidy on kerosene and the tax on gasoline should be reduced but taking distributional concerns into account the present structure of energy taxes is reasonable and the country may benefit by increasing the subsidy to kerosene taxing electricity and reducing the gasoline tax these conclusions are robust to changes in the relevant parameters representing the indonesian economy

household inequality social welfare and trade abstract working with sen social welfare functions meaning explicit separability between mean income and income dispersion we develop a generalized dual approach to tracking household inequality aspects of social welfare in general equilibrium we highlight how household equity can be examined analytically alongside production efficiency in duality based models using our dual framework to explore potential trade offs between efficiency and equity effects of trade policy our results complement the set of standard inequality results in trade theory focused on functional rather than household inequality we also find that the relative distributional impact of tariffs on welfare is conditional on the initial level of inequality

marginal conditional stochastic dominance this paper introduces the concept of marginal conditional stochastic dominance mcsd which states the conditions under which all risk averse individuals when presented with a given portfolio prefer to increase the share of one risky asset over that of another mcsd rules also answer the question of whether all risk averse individuals include a new asset in their portfolio when assets returns are correlated mcsd criteria are expressed in terms of the probability distributions of the assets and of the underlying portfolio an empirical application of mcsd is provided using stocks traded on the new york stock exchange mcsd rules are used to show that in the long run one cannot assert that the market portfolio is inefficient

nontaxable income and necessary consumption the rousseau s paradox of fiscal egalitarianism this article compares a tax method featuring flat rates and fixed allowances equal for all taxpayers surplus income tax method sitm procedure with a tax method featuring also flat rates and increasing personal allowances ipas to meet the amounts of necessary consumption required by the different living standards discretionary income tax method ditm procedure our results show that the ditm procedure generates an after tax income distribution less unequal and superior in terms of social welfare moreover the assumption for comparison purposes of identical total tax revenues leads to the corollary that the flat tax rate under the ditm is necessarily larger than the one under the sitm being thus the former taxmethod is more progressive than the latter these results imply an obvious paradox considering the commonly accepted principle that basic necessities are the same for everyone rousseau 1755 based on the results obtained in this article we have labelled this paradox as the rousseau s

measurement of income inequality experimental test by questionnaire abstract we reconsider some of the basic assumptions of the literature on inequality analysis students views on the meaning of inequality comparisons were elicited by means of a questionnaire involving both numerical and verbal questions the responses suggest that two important axioms the principle of transfers and decomposability are not universally accepted

the nature of heterodox economics heterodoxy serves as an umbrella term to cover the coming together of separate projects or traditions in answering the question what distinguishes heterodoxy from the orthodoxy the author argues that matters of ontology are central in answering the question how are the various traditions that make up the modern heterodoxy to be distinguished from each other the author defends criteria other than varying commitments to specific substantive theories policy measures or techniques or basic units of analysis

some classes of functions that preserve the inequality and welfare orderings of income distributions abstract we identify in the paper those classes of functions that preserve the ranking of distributions according to three welfare criteria introduced recently by a f shorrocks economica 50 1983 3 17 we prove that a necessary and sufficient condition for a function to preserve the generalized lorenz ordering of distributions is that it be increasing and concave requiring welfare improvements to be compatible with more equality we obtain linear resp affine functions when emphasis is placed on relative resp absolute income differentials

capping the cap implementation of the uruguay round agreement by the european union abstract this paper considers the detailed implementation of the uruguay round agreement on agriculture by the european union eu and its likely impact on the cap the agreement sets three constraints to agricultural support in developed countries the commitment to reduce domestic support by 20 per cent will have no effect tariffication and the new access provisions will only marginally improve the competitiveness of imports into the eu in the short run but do set the scene for more meaningful tariff cuts in the next round it is the constraints on subsidized exports which will most limit the cap and impact on world markets although even here the effects could easily be exaggerated the export constraints will bite deeper in the longer run particularly in the context of an enlargement of the eu to embrace several states from central and eastern europe which could trigger a more fundamental cap reform despite its limited impact the agreement should be judged a success in that it does impose limits on the cap and sets the scene for the next round of negotiations proposed to begin in 1999
