assessing the effects of wives earnings on family income inequality we argue that the effect of wives earnings can be assessed meaningfully only by comparing the observed distribution of income with a reference distribution the components of the standard decomposition of the gini coefficient have no implicit reference distribution and therefore should not be interpreted as a measure of the effect of an income source on inequality we suggest several intuitive counterfactual reference distributions and illustrate their use with 1979 and 1989 u s data we conclude that wives earnings reduced inequality in that the income distribution would have been less equal in their absence alternative measures of the impact have mixed results

entrepreneurship and income inequality in southern ethiopia this article uses inequality decomposition techniques in order to analyze the consequences of entrepreneurial activities to household income inequality in southern ethiopia a uniform increase in entrepreneurial income reduces per capita household income inequality this implies that encouraging rural entrepreneurship may be favorable for both income growth and income distribution such policies could be particularly successful if directed at the low income low wealth and relatively uneducated segments of the society

in search of smoking guns what makes income inequality vary over time in different countries we investigate the forces affecting the distribution of income by analyzing an unbalanced panel of information for 16 industrialized countries for the years 1966 through 1994 income inequality is measured with the gini coefficient of equivalent disposable income individuals are the unit of analysis the statistical analysis uses panel methods the results suggest that many factors affect the development of income inequality some factors are strictly economic a decreased industrial sector generally fosters inequality and some support is found for the view that increased trade of manufactured goods from developing countries is also a factor other forces are outside a strictly defined market sphere low inequality is found when a large proportion of the labor force belongs to a trade union and also when there is a large public sector in addition demographic circumstances are important since the proportion of the population under age 15 has a positive effect on inequality we find however no association between the unemployment rate and inequality

nonlinear dynamics in deviations from the law of one price a broad based empirical study abstract in this paper we test empirically the validity of the law of one price using data for five major bilateral us dollar exchange rates and nine goods sectors during the recent floating exchange rate regime since the early 1970s using threshold autoregressive models we find strong evidence of nonlinear mean reversion in deviations from the law of one price with plausible convergence speeds consistent with theoretical arguments on international goods markets arbitrage under transactions costs and with an emerging strand of empirical literature these results contribute towards forming a consensus view in favor of discrete regime switching in deviations from the law of one price and the presence of differing nonzero transactions costs across a broad range of goods and countries

does microcredit increase household welfare in the absence of microinsurance summary this study answers the question does a combination of microcredit and microinsurance improve the wellbeing of low income households we examine this challenge through heckman sample selection instrumental variable and treatment effect models the findings indicate that households using microcredit in combination with microinsurance derive significant gains in terms of welfare improvement microcredit may be good but its benefit to the poor is enhanced and sustained if the poverty trapping risks are covered with microinsurance to this extent combining microcredit with microinsurance will empower the poor to make a sustainable exit from poverty

imputed income from owner occupied housing and income inequality imputed income from owner occupied housing is generally not included in analyses of the distribution of income yet the value of homeownership is undoubtedly an important element distinguishing the economic status of one family from another in this paper using a new method to decompose income inequality by income source we analyze the impact of potential income derived from the net worth of housing on a representative national sample of us homeowners using 1980 survey of residential finance data we find that housing income adds less to inequality per dollar of income than does income from all other sources

poverty comparisons over time and across countries in africa abstract we use demographic and health surveys dhs to compare poverty at two or more points in time within and between african countries our welfare measure is an index resulting from a factor analysis of various household characteristics durables and household heads education an advantage of this measure is that for intertemporal and intraregional comparisons we need not rely on suspect price deflators and currency conversion factors the wide availability and similarity of questionnaires of the dhs facilitate comparisons over both time and countries our results generally show declines in poverty during the previous decade largely due to improvements in rural areas

segmentation of consumer markets in the us what do intercity price differences tell us we quantify the magnitude of market segmentation in us consumer market and explore the underlying factors behind this segmentation using a quarterly panel of retail prices for 45 products in 48 us cities from 1985 to 2009 the extent of market segmentation is estimated using city pair price differences within the framework of both linear autoregressive ar and nonlinear threshold autoregressive tar models we find that the magnitude of market segmentation varies from one product to another but even more across city pairs in each product contrary to a widespread perception market segmentation within the us is not necessarily larger for non tradable services compared to tradable goods we identify potential drivers of market segmentation by relating the cross city and cross product variations of market segmentation to location specific and product specific characteristics distance relative city sizes differences in wage and rent type of product and proximity to marketplace distance which captures more than transport costs turns out to be the most salient factor even after controlling for a range of other potential factors the effect of distance however varies substantially across products with perishable products and locally produced products showing larger distance effect on market segmentation we find that the magnitude of market segmentation has been somewhat stable during the sample period but intercity price differences have become more sensitive to distance over time in many products under study

fiscal redistribution and income inequality in latin america income inequality in latin america ranks among the highest in the world it can be traced back to the unequal distribution of assets especially land and education in the region but the extent to which asset inequality translates into income inequality depends on the redistributive capacity of the state this paper documents the performance of latin american fiscal systems from the perspective of income redistribution using newly available information on the incidence of taxes and transfers across the region the findings indicate that i the differences in income inequality before taxes and transfers between latin america and western europe are much more modest than those after taxes and transfers ii the key reason is that in contrast with industrial countries in most latin american countries the fiscal system is of little help in reducing income inequality and iii in countries where fiscal redistribution is significant it is achieved mostly through transfers rather than taxes these facts stress the need for fiscal reforms across the region to further the goal of social equity however different countries need to place different relative emphasis on raising tax collection restructuring the tax system and improving the targeting of expenditures

economic issues in tariffication an overview abstract the agricultural trade liberalization proposal known as tariffication aims at converting all existing non tariff barriers ntbs to trade into bound tariffs and to reduce these tariffs over time this is in tune with the original philosophy of the general agreement on tariffs and trade gatt and it calls for a dramatic overhaul of existing agricultural policies in many developed countries the main economic issues that arise with tariffication stem from the non equivalence of tariffs and ntbs in a number of scenarios this paper analyzes non equivalence arising from the existence of imperfect competition in importing countries price instability in importing and exporting countries and inefficient allocation of quantitative restrictions it is shown that in all these cases the definition of an appropriate equivalent tariff to be used in tariffication is not straightforward and that in general this equivalent tariff cannot be computed on the basis of only observed price differences between countries tariff rate quotas which are meant to be the main tool of implementation of tariffication according to the existing proposal are analyzed in some detail concerning the relationship between tariffication and the other elements of the trade liberalization package it is shown that tariffication would limit the scope of export subsidy policies it is also shown that the existence of production and export subsidies makes observed price gaps between countries of questionable value in setting equivalent tariff levels finally it is argued that the main focus of tariffication should be the conversion of ntbs to acceptable long run bound tariffs rates and considerable flexibility in this conversion process could be exercised in the transition period

an interim evaluation of sulfur dioxide emissions trading ide iv of the 1990 clean air act amendments established the first large scale long term environmental program to rely on tradable emissions permitscalled allowances in this program to control pollution this program was designed to cut acid rain by reducing sulfur dioxide so2 emissions from electric generating plants to about half their 1980 level beginning in 1995 it is of interest both as a response to an important environmental issue and as a landmark experiment in environmental policy this experiment comes at a particularly important time since emission trading is under serious consideration with strong u s backing for use to deal with global climate change by curbing emissions of carbon dioxide co2 the economic stakes in climate change surpass those in acid rain by several orders of magnitude intergovernmental panel on climate change 1996 this article summarizes the results to date of our ongoing empirical analysis of compliance costs and allowance market performance under the u s acid rain program

price index convergence among united states cities we study the dynamics of price indices for major u s cities using panel econometric methods and find that relative price levels among cities mean revert at an exceptionally slow rate in a panel of 19 cities from 1918 to 1995 we estimate the half life of convergence to be approximately nine years the surprisingly slow rate of convergence can be explained by a combination of the presence of transportation costs differential speeds of adjustment to small and large shocks and the inclusion of nontraded goods prices in the overall price index do price indices in major u s cities share a common trend and if so how quickly do they revert to that trend following a local shock to the price index to answer this question we study the dynamics of consumer price indices for 19 major u s cities over the period from 1918 to 1995 the panel time series methods we employ are now commonly used for studying real output growth rates and levels of real exchange rates across countries we estimate that price index divergences across u s cities are temporary but surprisingly persistent with a half life of nearly nine years our research has two primary motivations first we hope to gain a better understanding of the sources of persistence in the deviations from purchasing power parity ppp found in studies of national price indices and exchange rate data second and more importantly we see the european monetary union as having many similarities to the united states and believe that studying the behavior of prices across u s cities will help us in understanding the likely nature of inflation convergence in the euro area the european central bank s stated inflation objective is a year on year change in the harmonized index of consumer prices hicp of not more than 2 but how large might we expect regional deviations from this euro area wide average to be and how long are they likely to persist the lack of data prevents us from answering this question directly using european prices under monetary union instead we look to the united states a mature common currency area of similar regional diversity size and industrial development

unemployment and income distribution time series evidence from sweden for a long time swedish politicians have been devoted to keeping unemployment at low levels the main reason for this devotion is probably the belief that higher unemployment increases inequality of income and welfare this is a reasonable belief since unemployment risks are highest among people with low earnings capacity even when they have a job by means of micro data it is easy to verify a marked low income profile of unemployment further the swedish unemployment insurance system replaces only about 70 per cent of foregone income and quite many unemployed do not qualify for any benefits see bjorklund and holmlund 1991 increases in unemployment however are associated with many changes in the economy with complex consequences for the personal distribution of income in addition to the income losses suffered by those who become unemployed higher unemployment also affects the factor shares of income the profit share typically declines during recessions and because upper income groups receive a relatively high proportion of their income from capital income a countervailing mechanism is involved changes in unemployment also affect inflation which in turn might influence the personal distribution of income the distributional effects of inflation are an open question this note makes an investigation into the relationship between unemployment and the personal distribution of income using swedish time series data the method was first used on u s data by blinder and

tax policy the interest elasticity of saving and capital accumulation numerical analysis of theoretical models increasing disillusionment with traditional empirical methods is having a major impact on research methodology which is increasingly turning to simulation analysis based on theoretical models and assumed parameter values in research on saving and wealth accumulation there have been several recent studies consisting of simulation of theoretical models based on the life cycle model a particular focus has been tax policy and capital formation which is the area of concentration of this paper the aim is to analyze in a theoretical simulation context the impact on saving and wealth of an increase in the after tax rate of return to saving generated by a cut in the tax rate on income from capital this paper suggests that such simulation analysis while instructive as to the behavior of the class of models examined and as to the critical channels of influence does not yield a theoretical presumption in favor of cutting taxes on income from capital as a means of stimulating capital formation the development of this literature derives in part from disillusionment with traditional empirical methods many such papers begin by listing a litany of the problems involved in the usual type of empirical analysis before proceeding to simulation of theoretical structures the implicit conclusion at times appears to be that because of the daunting problems of standard empirical methodology the results derived from it can be ignored and that empirical magnitudes can perhaps be discovered by deductive means the temptation to think of the precise numerical results derived from theoretical simulation as empirical can be rather strong it needs to be reemphasized that empirical magnitudes can only be determined by empirical studies in section i the theoretical structure of a zero bequest life cycle model2 is outlined and several numerical simulations of this model are presented these simulations highlight interesting and nontrivial interactions of theoretical parameters and also demonstrate the difficulty involved in attempts to develop robust aggregate implications from such a framework for instance it is argued that summers claim to have developed a prima facie theoretical case for a high interest elasticity of savings 1981a p 537 does not stand up to sensitivity analysis a small change in the assumed rate of pure time preference or in other parametric assumptions generate otherwise plausible cases in which the interest elasticity of aggregate saving is low the experiments conducted in section i are partial equilibrium in the sense that the interest rate is changed exogenously which changes savings and hence the capital stock but the feedback effect of the capital international monetary fund this paper derives from chs 2 and 3 of my doctoral dissertation completed during a research fellowship at the brookings institution financial support was received from brookings and the social science research council i am grateful to henry aaron barry bosworth maxim engers irwin friend laurence kotlikoff franco modigliani joseph pechman duncan ripley robert shiller patricia stack and my supervisor albert ando for comments and guidance on earlier drafts none of the above institutions or individuals is responsible for the views expressed or any remaining errors for example see james tobin and walter dolde betsy white lawrence summers 1978 1981a b g moore alan auerbach and laurence kotlikoff and auerbach kotlikoff and j skinner 2it is popular to establish a sharp dichotomy between life cycle models and bequest models this taxonomy ignores the frequent references to the potential significance of bequests in the writings of the originators of the life cycle hypothesis a distinction between zero bequest life cycle models and life cycle models incorporating bequests is more accurate in terms of doctrinal history see for example albert ando and franco modigliani and modigliani and richard brumberg

decomposing inequality in co2 emissions the role of primary energy carriers and economic sectors emission inequality across countries and the contribution of the energy mix and the sectoral composition of a country s energy use are of central importance to the climate debate we analyze the evolution of inequality in global co2 per capita emissions using both historical data on energy related co2 emissions and future emission scenarios generated with the integrated assessment model remind within our sample of 90 countries the results indicate that the gini index declined from about 0 6 in 1971 to slightly above 0 4 in 2008 a decomposition of the gini index of total emissions into primary energy carriers indicates that this reduction is mainly attributed to declining shares of emissions from coal peat and oil in total emissions and decreasing emission inequality within all fossil primary energy sources from the perspective of economic sectors the decline in overall inequality is almost entirely due to a decline of the contribution of emissions from manufacturing construction our analysis also suggests that an equally spread emission reduction from any one source would not have a major impact on overall emission inequality the analysis of future scenario data indicates that climate policy reduces absolute emission inequality while inducing drastic progressive emission reductions in all regions

wealth distribution in cuba 2006 2014 a first assessment using microdata recently a trend towards increasing inequality has been detected in both developed and developing countries most of these studies have been focusing on formal monetary variables since capitalism is a socioeconomic system where monetary relations play a paramount role however the distribution of non monetary assets is also very important especially so in less developed countries this paper applies a pca methodology to analyse the distribution of non monetary wealth in cuba a socialist country where the role of monetary relations is relatively minor utilizing the mics unicef microdata the paper provides for the first time an estimation of wealth distribution for three years 2006 2011 2014 by area and region the main results show a non monotonic wealth inequality reduction the initial worsening 2006 11 is more than counterbalanced by a recent improvement 2011 14

welfare ranking ad valorem and specific tariffs under monopolistic competition actual trade and tariff policy prefers ad valorem tariffs to specific tariffs yet in this paper we show that in a setting of monopolistic competition realizing a given restriction on imports via a specific tariff would generate more consumer utility than obtaining the same restriction via an ad valorem tariff jel classification f12 un classement en terme de bien etre des droits de douane ad valorem et specifiques quand on est en regime de concurrence monopolistique les politiques commerciales en vigueur pref rent les droits de douane ad valorem aux droits de douane specifiques or ce memoire montre que dans un contexte de concurrence monopolistique reduire les importations par le truchement d un droit de douane specifique genere plus d utilite pour le consommateur que les memes restrictions obtenues par le truchement d un droit de douane ad valorem

accounting for inequality trends decomposition analyses for the uk 1971 86 eight explanations for uk income inequality trends between 1971 and 1986 are assessed by pooling evidence from inequality index decompositions by population sub group and by income source the principal causes of the aggregate trends were a mixture of changes in earnings inequality employment structure and unemployment but this mixture changed over time the impact of wage inequality changes on income inequality changes fell during the 1970s and 1980s reflecting the secular decline in the importance of employment earnings for household income packages unemployment changes had their largest impact at the start of the 1980s between 1981 and 1986 self employment income changes appear to have had the largest influence

the shadow value of migrant remittances income and inequality in a household farm economy this article offers econometric evidence that income remittances sent home by family migrants stimulate household farm incomes indirectly by relieving credit and risk constraints on household farm production a high but unequally distributed shadow value of migrant remittances appears to reinforce an equalising direct effect of remittances on the income distribution across a sample of household farms in rural mexico

multidimensional poverty in crisis lessons from zimbabwe abstractzimbabwe experienced an acute social political and economic crisis from 2001 to 2008 and is now on a recovery path this paper explores changes in poverty between 2001 2007 and 2011 2012 using an alkire foster multidimensional poverty index results indicate a large increase in poverty across multiple dimensions of household wellbeing between 2001 and 2007 the start of the crisis peak followed by a decrease in poverty between 2007 and 2011 2012 during the recovery period decomposition of the index shows significantly different trends in poverty dimensions over time with implications for short and long term social assistance policies

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

modelling priority patterns in asset acquisition the case of smallholder farmers in three rural districts in uganda poor smallholder farmers in uganda live at or below subsistence level they are vulnerable to multiple risks and insecurities and have limited access to capital markets in this article we propose a model to estimate household priority patterns in asset acquisition using cross section data the model is applied to a field survey consisting of 938 farm households from three districts the model predicts the distribution of asset ownership conditional on the type of assets owned based on the established priority patterns the article proposes a low cost regional poverty monitoring instrument using only asset type data

inequality of income derived from survey data during the inflationary period abstract by using the lorenz curve technique this note demonstrates that the inequality of income derived from survey data during the inflationary period is overestimated

free entry and social inefficiency our goal is to provide a simple yet general exposition of the conditions under which the number of entrants in a free entry equilibrium is excessive insufficient or optimal our analysis compares the number of firms that enter a market when there is free entry with the number that would be desired by a social planner who is unable to control the behavior of firms once they are in the market that is we consider the second best problem of choosing the welfare maximizing number of firms while we take as given their noncompetitive behavior after entry we demonstrate that the crucial conditions for establishing the presence of an entry bias can be stated quite simply in terms of the outcome of the postentry game played by entrants in contrast to previous work we do not need to model this postentry game explicitly

poverty in african households the limits of survey and census representations african poverty statistics depend on household level measurements from survey data making the definition of household of critical importance detailed case studies from tanzania and burkina faso explore 1 understandings of household membership and ambiguities and 2 how well survey definitions capture households as economic units and the implications for household size and responses to and mitigation of poverty we develop an analytic framework of open and closed households open households cope with poverty using flexibility movement and extra household networks but are poorly represented by survey data closed households are likely to be better described by survey data

shocks income and wealth do they affect the extraction of natural resources by rural households summary this paper examines the effects of household and village level characteristics on environmental reliance and participation in resource extraction decisions unlike previous analyses that used case studies or regional samples i use a nationally representative sample of rural households rounds i and ii of the mexico national rural household survey enhrum econometric results show that participation in resource extraction follows an inverted u shaped relationship with income and that environmental reliance decreases with income beyond income results show that relatively wealthy households in rural mexico are less likely to participate in resource extraction and have lower reliance than those with less wealth there is also clear evidence that natural resources provide some sort of insurance for households that are subjected to negative agricultural shocks

the future of the income tax the federal income tax has been under attack by the economics profession for more than a decade the attack comes from two directions supply siders who believe that progressive income taxation impairs economic incentives and more traditional economists who would substitute a progressive expenditure tax for the income tax 2 at one time support for the expenditure tax was confined to a few members of our profession including such distinguished names as john stuart mill irving fisher nicholas kaldor and james meade today it is fair to say that many if not most economists favor the expenditure tax or a flat rate income tax this group has joined the opponents of progressive taxation in the attack on the income tax despite an incessant barrage from both groups no country in the world is planning to abandon the income tax or is even considering a personal expenditure tax a wave of tax reform beginning with the u s reform in 1986 has been sweeping the world aimed at improving the income tax not at eliminating it tax preferences formerly regarded as sacrosanct are being removed and there is a distinct movement toward comprehensive income taxation 3 however individual income tax rates are being cut tax progressivity has been declining almost everywhere and reliance on the income tax has been diminishing it will come as no surprise to this audience that i approve of the base broadening feature of the current tax reform movement but i believe that the reduction in the redistributive effect of the income tax has gone too far in this paper i shall show that the progressivity of the u s tax system never very pronounced except during and immediately after the two world wars has been declining for more than two decades and that the tax reform act of 1986 reversed this decline but only slightly consequently we have a long way to go to improve the equity of the tax system i believe this can be done without punitive tax rates that will hurt economic incentives i begin with a brief review of recent changes in the u s distribution of income and follow this with an analysis of the effect of taxes on the income distribution i next examine arguments for and against the income tax with particular emphasis on its effects on economic incentives and its merits when compared with the expenditure tax i then evaluate the income tax as it emerged from the 1986 tax reform and conclude with tjoseph pechman passed away on august 19 1989 his presidential address was delivered at the onehundred second meeting of the american economic association december 29 1989 atlanta georgia joseph a pechman economic studies program the brookings institution 1775 massachusetts avenue nw washington dc 20036 i have benefited from the comments and suggestions on an earlier draft of this paper by henry j aaron richard goode jane g gravelle robert w hartman donald w kiefer herbert e klarman robert d reischauer clifford m winston and h peyton young but they should not be held responsible for the views expressed in this paper i am indebted to richard kasten for various simulations i am also grateful to stephen j kastenberg for research assistance and to diane a shugart valerie m owens and sara c hufham for secretarial assistance some of the more extreme supply siders argued that large tax cuts pay for themselves see for example laffer 1981 but i believe it is fair to say that this view has been totally discredited for a more reasonable supply side view see the economic report of the president 1982 2see for example michael j boskin 1978 david e bradford 1980 charles l ballard don fullerton john shoven and john whalley 1985 paul courant and edward gramlich 1982 martin feldstein 1978 robert hall and alvin rabushka 1985 john kay and mervyn king 1983 charles mclure 1987 mieszkowski 1980 and lawrence summers 1981 it is interesting that the recent popularity of the expenditure tax among economists was stimulated by a tax lawyer william d andrews 1974 3see pechman 1988

do different types of assets have differential effects on child education evidence from tanzania to assess the conventional view that assets uniformly improve childhood development through wealth effects this paper tests whether different types of assets have different effects on child education the analysis indicates that household durables and housing quality have the expected positive effects but agricultural assets have adverse effects on highest grade completed and no effects on exam performance extending the standard agricultural household model by explicitly including child labor the study uses three waves of panel data from tanzania to estimate the effects of household assets on child education the analysis corrects for the endogeneity of assets and uses a hausman taylor instrumental variable panel data estimator to identify the effects of time invariant observables and more efficiently control for time invariant unobservables the negative effect of agricultural assets is more pronounced among rural children and children from farming households presumably due to the higher opportunity cost of their schooling

inference tests for gini based tax progressivity indexes distribution free statistical inference procedures for changes in lorenz and gini based indexes of tax progressivity are developed and applied related but distinct tests for the reynolds smolensky index of residual progression and the kakwani index of liability progression are provided the inference procedures are illustrated by applying them to luxembourg income study microdata for sweden the united kingdom and the united states before and after periods of tax reform in each country a finding of significant change depends on the choice among progressivity indexes no single index exhibits a consistent pattern of significant change in all countries across time

sample audit tax assessment for businesses what s fair how should a revenue agency assess a business taxpayer s income on the basis of a sample audit of transactions the agency would like to maximize revenue while minimizing the risk that the taxpayer will be assessed more than he really owes the taxpayer reasons that overassessment is worse than underassessment as far as he is concerned and therefore the taxpayer might reasonably argue that the lower bound of a one sided confidence interval should be used by the assessor the revenue agency might understandably take a different point of view the revenue agency might argue that overassessment is really no worse than underassessment from its point of view so the midpoint of such a confidence interval should be used in fact it is this latter position that is currently in use most commonly by state agencies but such practice is being challenged the courts will have to make a decision

using an asset index to assess trends in poverty in seven sub saharan african countries summary using comparable nationally representative surveys and extending the work of sahn d e stifel d c 2000 poverty comparisons over time and across countries in africa world development 28 12 2123 2155 an asset index is used to investigate changes in poverty in seven african countries poverty declined in five of the seven countries improvements in the asset index are driven by progress in the accumulation of private assets while access to public services has deteriorated however the method has some shortcomings assets are slow changing and discrete the index therefore may not capture changes in well being accurately the poor discrimination ability of the index at the lower end of the scale also makes it an inappropriate tool for studying ultra poverty

marginal tax rates and income inequality in a life cycle model in this paper we perform computational counterfactual experiments to examine the quantitative impact of marginal tax rates on the distribution of income our methodology builds on previous simulation models developed by auerbach and kotlikoff and fullerton and rogers and uses an algorithm that allows us to examine marginal tax rate structures in their literal form we find that distortions associated with particular marginal tax rate structures have sizable effects on income inequality in a reasonably quantified life cycle setting in our baseline experiments the change in steady state income inequality under 1989 u s income tax rates vis a vis 1984 rates is about half as large as the change actually seen in the data over those two years when measured in terms of a monetary metric derived from gini coefficients

opening a can of worms the pitfalls of time series regression analyses of income inequality this paper argues that time series regression analysis is of only very limited use for understanding the determinants of income inequality the argument is based on a combination of results from the time series econometrics literature and several characteristics of inequality itself principally nonstationarity of the data in most inequality regression models and the weak theoretical foundations underlying the models a sample of postwar us data is used to illustrate the problems involved

greenhouse gas emission controls and firm locations in north south trade this paper studies greenhouse gas emission ghg controls in the presence of international carbon leakage through international firm relocation in a new economic geography model with two countries north and south only north sets a target for ghg emissions we compare the consequences of emission quotas and emission taxes under trade liberalization on location of two manufacturing sectors with different emission intensities and degrees of carbon leakage with low trade costs further trade liberalization increases global emissions by facilitating carbon leakage regulation by quotas leads to spatial sorting resulting in less carbon leakage and less global emissions than regulation by taxes

taxation and the earnings of husbands and wives evidence from sweden i examine the response of husbands and wives earnings to a tax reform in which husbands and wives tax rates changed independently allowing me to examine the effect of both spouses incentives on each spouse s behavior i analyze the large swedish tax reform of 1990 1991 and find that in response to a compensated fall in one spouse s tax rate each spouse s earnings rise i compare these results to those of simplified econometric models used in the typical setting in which independent variation in each spouse s tax rate is unavailable i find that standard econometric specifications may produce substantially biased estimates

poverty and the rural nonfarm economy in oromia ethiopia the rural nonfarm sector has gained increasing importance not only in asia but also in africa it is however widely believed that in most parts of africa the growth of the nonfarm economy has increased inequality and has had a limited effect on the poor who face entry barriers to nonfarm activities the present article analyzes the relation between nonfarm income poverty and inequality in oromia ethiopia we use two complementary methodologies i econometric estimates of household income from the nonfarm sector and ii a gini decomposition of analysis income inequality by source the results consistently indicate that in oromia entry barriers to nonfarm activities is low and the general growth of the sector will benefit the poor

the impact of macroeconomic policies on income distribution an empirical study of the philippines there has been a growing awareness of the income distribution dimension of macroeconomic policies this paper studies this issue empirically considering the case of the philippines and using data available from integrated surveys of households after estimating a reduced form equation it was found that underemployment inflation and government spending worsen income distribution while productivity gains the real interest rate and the real exchange rate were found to improve distribution a similar pattern emerges when the effects of these variables on the absolute incidence of poverty are estimated excerpt

barriers to price convergence this paper investigates the existence of convergence clubs in the cross country price mechanism for 96 individual goods retail price levels across 40 countries available semi annually for 1990 2010 using a nonlinear factor model and threshold regression tools to our knowledge this is the first paper to find strong evidence for club convergence of retail prices these clubs emerge due to the interaction of traded and non traded factors for example countries that are physically closer to potential trade partners converge faster than countries in the high distance regime as long as they have low initial labor productivity or low initial income moreover being behind the technology frontier appears to be more conducive to price convergence for countries with relatively small physical distance from potential trade partners we interpret our findings as evidence of a local law of one price due to barriers to price convergence that influence the duration of the effect of price shocks

structural unemployment cyclical unemployment and income inequality this is the first study that decomposes unemployment into its structural and cyclical components and investigates their impact on income distribution controlling for the influence of inflation increases in structural unemployment have a substantial aggravating impact on income inequality inflation has a progressive impact which is due to the unexpected component the study demonstrates that previous work failed to take into account the stochastic trend behavior of the variables consequently specifications used by previous research cannot predict the behavior of income shares after 1983 whereas the specification used by this paper generates accurate forecasts the results also indicate that a sustained gnp growth is not necessarily associated with an improvement in income inequality because sustained gnp growth can coexist with increased structural unemployment

tax reform 1986 and marginal welfare changes for labor during the 1980s in the united states before tax income shifted away from the poor and toward the upper income groups changing the distribution of tax burdens or after tax income is one way to redress a growing imbalance in before tax income pechman 14 feldstein 6 and wallace et al 17 have all shown that the tax reform act of 1986 tra86 increased the progressivity of the combined personal and corporate income taxes an achievement not accomplished in the last two decades of income tax reform 14 tax reform can also increase or decrease the welfare of individuals in an economy through its effect on the allocation of labor supply resources tra86 reduced the highest marginal income tax rates from 50 percent to 28 percent for high income persons and removed some lower income persons from the tax roles such large marginal tax rate changes introduce significant potential for increased economic efficiency in labor supply and for welfare gains for the rich and poor alike these changes should be part of the benefit analysis of tax reform indeed hausman and poterba 10 report welfare cost changes that result from tra86 for the average male and female their estimates however do not account for welfare cost changes throughout the income distribution in addition to our use of microdata to estimate the marginal welfare cost of tax reform we use more precise measures of marginal tax rates than other researchers in this paper we use browning s partial equilibrium framework to examine the influence of the reduction in marginal tax rates from tra86 on the distribution of welfare gains from labor supply reallocation for males by population decile and for females by population decile and by marital status the empirical results illustrate how the tax reform affected low income female household heads where poverty is so heavily concentrated as well as other household heads and spouses the results indicate that tra86 reduced welfare costs in the economy but these welfare

measuring vulnerability to asset poverty in sub saharan africa summary this paper presents a methodology to measure vulnerability to asset poverty using repeated cross section data age cohort decomposition techniques focusing on second order moments can be used to identify and estimate the variance of shocks on assets and therefore the probability of being poor in the future estimates from the ghana living standard surveys show that expected asset poverty is a reliable proxy for expected consumption poverty applying the methodology to eight demographic health surveys countries households in rural areas are found to be unambiguously more vulnerable to poverty than those in urban areas

equity effects of the tax reform act of 1986 the major goals of the tax reform act of 1986 included an increase in the equity of the tax system but equity is a concept that is difficult to evaluate one dimension of equity involves vertical equity the idea that people of different income should be treated differently by the tax code this notion is often closely linked with the idea that the tax code should be at least somewhat progressive the tax reform act has also been characterized as favoring lower income individuals relative to higher income ones six million lowincome families were removed from the tax roles through increased standard deductions and personal exemptions and the earned income tax credit which refunded taxes to low income workers was expanded a second dimension of equity is horizontal equity the attempt to be sure that individuals with equal incomes are treated equally the tax reform act took many steps toward equalizing the treatment of different types of income it converted the personal tax rate schedule into two rates eliminated longstanding tax benefits such as the investment tax credit and the capital gains exclusion curtailed recently enacted incentives such as accelerated depreciation and individual retirement accounts struck deeply at popular tax shelters cut the top marginal tax rate for individuals by over one third and reduced the corporate tax rate by over one quarter but although efficiency gains have been

traditional wealth modern goods and demographic behavior in rural senegal summary the study investigates the relationships of demographic indicators fertility mortality marriage education with modern and traditional wealth in rural senegal data were based on rural households interviewed in the 2011 dhs survey an absolute wealth index was computed from a list of 15 modern goods a traditional wealth index was computed from data on land and livestock per capita modern wealth was always associated with modern demographic behavior lower fertility lower mortality higher age at marriage higher level of education whereas traditional wealth was not associated with fertility and mortality and was negatively associated with marriage and education

nonfarm employment and rural welfare evidence from the himalayas the potential importance of nonfarm employment for the welfare of rural households has long been recognized but whether the nonfarm sector offers prospects for improving the welfare of the rural poor remains a contentious issue we examine distributional and well being effects of nonfarm employment of rural households in the himalayas we account for heterogeneity of nonfarm employment and estimate a system of structural equations to better understand the causal linkages between nonfarm employment and household well being the results confirm that disaggregating nonfarm employment activities matters for understanding the relationship between nonfarm employment and rural welfare while low return nonfarm employment is associated with lower income inequality high return nonfarm activities have a disequalizing effect on the distribution of household incomes we also find that the ability to engage in high return nonfarm activities is associated with higher economic well being poor households on the other hand tend to rely on low return activities that do not contribute to improved well being

in the eye of the storm the welfare impacts of a hurricane summary the impact of a large covariant shock namely hurricane mitch is examined in the context of household asset holdings in rural nicaragua utilizing household panel data from the period it is found that the hurricane did not have an adverse impact on the ownership of productive assets among the affected households on average on the other hand nonproductive asset holdings seem to have been significantly reduced a further examination confirms that the shock affected the poorest households disproportionally especially in terms of nonproductive assets finally this study presents strong suggestive evidence of a geographical poverty trap within the shock affected areas of the country

price setting in online markets basic facts international comparisons and cross border integration we document basic facts about prices in online markets in the united states and canada which is a rapidly growing segment of the retail sector relative to prices in regular stores prices in online markets are more flexible and exhibit stronger pass through 60 75 percent and faster convergence half life less than two months in response to movements of the nominal exchange rate multiple margins of adjustment are active in the process of responding to nominal exchange rate shocks properties of goods sellers and markets are systematically related to pass through and the speed of price adjustment for international price differentials

the distribution of income and wealth of farm operator households because of the relatively low incomes of people associated with farming in the past income maintenance has been a major focus of farm policy the average money income of families earning farm self employment income in 1983 was 93 of the average money income of other u s families usdc however an average income of farm households has lost much of its meaning because it masks a great deal of variation compared to the past farm households represent a heterogenous population presenting a new challenge to policy makers concerned about framing income maintenance policies the current farm bill debate began in 1984 amidst piecemeal information on increased bankruptcies and general financial stress of farms analysis of the financial leverage and cash flow positions of farm businesses has since been forthcoming johnson baum and prescott however information on the financial well being of those households associated with farming has remained limited the purpose of this paper is to describe the financial well being of farm operator households by measuring their size distribution of personal income and farm equity in 1984 the contribution of each source of income to the total inequality of incomes is also analyzed

politics and the structural dependence of the state in democratic capitalist nations i explore empirically a central claim of the structural dependence thesis namely that capitalists ability to disinvest fundamentally conditions policy choices in democratic capitalist systems utilizing time series data for 16 affluent democracies from 1965 to 1984 i find that indeed low rates of business investment are associated with reductions in corporate tax burdens and that these reductions are more pronounced in periods of economic crisis moreover low rates of capital formation engender cuts in personal income taxes during periods of economic stress however i also find that the magnitude of responsiveness of taxation to low rates of investment is relatively small and that analyses of the political context of investment and taxation indicate that governments have choices the responsiveness of corporate tax burdens to capital formation may under some governments be part of a policy mix designed to maintain adequate investment and to address the demands of core constituencies

wage policies of a russian firm and the financial crisis of 1998 evidence from personnel data 1997 to 2002 the authors use a rich personnel data set from a russian firm for the years 1997 to 2002 to analyze how the firm adjusts wages and employment during this period in which local labor market conditions changed in the aftermath of the financial crisis in 1998 they relate the development of turnover and wages for various employment categories to alternative models of wage and employment determination the authors argue that the firm s behavior is consistent with the predictions of efficiency wage models of the shirking and turnover type

measuring the effects of socio economic variables on the income distribution an application to the east german transition process this paper develops a discrete variant of the semiparametric methodology of dinardo fortin and lemieux 1996 dfl to measure the effects of socio economic variables on the income distribution although the proposed method is also based on the calculation of hypothetical income distributions by reweighting the original population it is much easier to implement the framework is applied to examine the distributional effects of rising unemployment decreasing female labor market participation and widening income structure in east germany following the reunification with west germany in 1990 the empirical results suggest that both these tendencies contributed considerably to the recent increase in income inequality in east germany

the purchasing power parity debate originally propounded by the 16th century scholars of the university of salamanca the concept of purchasing power parity ppp was revived in the interwar period in the context of the debate concerning the appropriate level at which to re establish international exchange rate parities broadly accepted as a long run equilibrium condition in the post war period it first was advocated as a short run equilibrium by many international economists in the first few years following the breakdown of the bretton woods system in the early 1970s and then increasingly came under attack on both theoretical and empirical grounds from the late 1970s to the mid 1990s accordingly over the last three decades a large literature has built up that examines how much the data deviated from theory and the fruits of this research have provided a deeper understanding of how well ppp applies in both the short run and the long run since the mid 1990s larger datasets and nonlinear econometric methods in particular have improved estimation as deviations narrowed between real exchange rates and ppp so did the gap narrow between theory and data and some degree of confidence in long run ppp began to emerge again in this respect the idea of long run ppp now enjoys perhaps its strongest support in more than 30 years a distinct reversion in economic thought

transactions costs and nonlinear adjustment in real exchange rates an empirical investigation eolquilibrium models of real exchange rate determination in the presence of transactions costs imply a nonlinear adjustment process toward purchasing power parity ppp conventional cointegration tests which ignore the effect of transactions costs may be biased against the long run ppp hypothesis our results using both monthly data for the interwar period and annual data spanning two centuries clearly reject the linear framework in favor of an exponential smooth transition autoregressive process the systematic pattern in the estimates of the nonlinear models provides strong evidence of mean reverting behavior for ppp deviations and helps explain the mixed results of previous studies

measuring socio economic status in the millennium villages the role of asset index choice how are poverty analyses and poverty traps assessments affected by the choice among conventional methods of asset index construction to address this question this article uses panel data from four sites in the millennium villages project mvp in malawi tanzania mali and ghana to study the relationship between eight asset indices and the sensitivity of findings related to poverty rates poverty transitions and poverty traps to the index used we find that although estimations of poverty rates and transitions are largely consistent across indices evidence of poverty traps can be conditional on which asset index is used the asset indices studied include structural income principal components factor analysis and a reduced set of assets reflecting the portfolio assessed in the demographic health survey dhs data

lifetime earnings inequality in germany we employ german social security records to investigate intragenerational lifetime earnings inequality and mobility of yearly earnings for 35 cohorts starting with the birth year 1935 our main result is a striking secular rise of intragenerational inequality in lifetime earnings west german men born in the early 1960s are likely to experience about 85 more lifetime inequality than their fathers in contrast both short term and long term intragenerational mobility are stable longer unemployment spells of workers at the bottom of the distribution of younger cohorts contribute to explaining 20 40 of the overall increase in lifetime earnings inequality

trade policy with endogenous entry revisited abstract this paper revisits the effects of tariffs and quotas in a competitive setting where three results are thought to hold these are that quotas are equivalent to specific tariffs the form of tariffs specific or ad valorem does not matter and that the way in which a quota is allocated has no real effects as it only affects the allocation of rents not their size we show that all three of these results are false when entry exit is endogenous equivalence holds only if the initial level of entry is set at the long run level under the quota

linking yitzhaki s and dagum s gini decompositions in this article we show that the gini coefficient is simultaneously decomposable both by sources of income and by populations of income receivers for nonoverlapping income distributions the so called first best gini multi decomposition we show that this multidimensional decomposition is useful for many reasons i it is related to the degree of inequality aversion of the decision maker ii it is especially well suited to study inequalities between poor and nonpoor people iii it enables one to measure the impact of marginal tax reforms on within and between group inequalities respectively

does distance reflect more than transport costs we decompose the effect of distance on intercity retail price dispersion in us into transport and non transport cost components we find that distance contains more information than transport costs care should be taken in interpreting distance effect as transport costs only

a more efficient estimate of the effects of macroeconomic activity on the distribution of income the effects of unemployment and inflation on quintile shares of family income in the united states are estimated by means of generalized least squares inflation is found to have a significant progressive impact on the distribution of income the results also lend support to earlier findings regarding the regressive effects of unemployment copyright 1994 by mit press

the role of two frictions in geographic price dispersion when market friction meets nominal rigidity this paper empirically investigates and theoretically derives the implications of two frictions market friction and nominal rigidity on the dynamic properties of intra national relative prices with an emphasis on the interaction of the two frictions by analyzing a panel of retail prices of 45 products for 48 u s cities over the period 1985 2009 we make two major arguments first the effect of each type of friction on the dynamics of intercity price gaps is quite different while market frictions arising from physical distance and transportation costs have a positive impact on volatility and persistence of intercity price dispersion nominal rigidities have a positive impact on persistence but a negative impact on volatility this empirical evidence is different from what is predicted by standard theoretical cross country models based on price stickiness second complementarities exist between market frictions and nominal rigidities such that the marginal effect of a market friction dwindles as nominal rigidities increase we provide an alternative theoretical explanation for this finding by extending the state dependent pricing sdp model of dotsey et al 1999 and show that our two city model with nominal rigidity and market frictions can successfully explain the salient features of the dynamic behavior of intercity price differences that have not been captured in previous analysis

income inequality income composition and macroeconomic trends israel 1979 93 the paper offers several explanations for income inequality trends in israel during 1979 93 two types of analysis are employed decomposition of the gini coefficient by income source and population sub group and time series regression on macroeconomic variables it is found that the slight increase in inequality over the period is a result of opposing forces and that the major difference between the inflation 1979 84 and stabilization 1985 93 periods is in the inequality reducing effect of direct taxes increasing in the first period while declining in the second unemployment had a regressive impact whereas inflation acted as a progressive tax in the first period but not in the second
