the impact of price discrimination on consumer surplus at popular music concerts abstract we estimate consumer surplus gains and losses from concert ticket price discrimination fans purchasing low priced tickets enjoy a surplus gain of about 9 26 per ticket while high priced ticket buyers suffer a loss of about 17 63 per ticket

is economic growth good for the poor tracking low incomes using general means in this paper we propose the use of an alternative methodology to track low incomes based on atkinson s 1970 family of equally distributed equivalent income functions which are called general means here we provide a new characterization of general means that justifies their use in this context our method of evaluating the effects of growth on poor incomes is based on a comparison of growth rates for two standards of living the ordinary mean and a bottom sensitive general mean the motivating question is to what extent is growth in the ordinary mean accompanied by growth in the general mean a key indicator in this approach is the growth elasticity of the general mean or the percentage change in the general mean over the percentage change in the usual mean our empirical analysis estimates this growth elasticity for a data set containing 144 household surveys from 20 countries over the last quarter century among other results we find that the growth elasticity of bottom sensitive general means is positive but significantly smaller than one this suggests that the incomes of the poor do not grow one for one with increases in average income

can foreign aid reduce income inequality and poverty this paper s goal is to examine the effect of foreign aid on income inequality and poverty reduction for the period 1971 2002 since simple cross country regressions cannot be taken as true time series findings we focus on dynamic panel data techniques which allow accounting for potential simultaneity and heterogeneity problems we find some weak evidence that foreign aid is conducive to the improvement of the distribution of income when the quality of institutions is taken into account however this result is not robust this finding is consistent with recent empirical research on aid ineffectiveness in achieving economic growth or promoting democratic institutions

a note on the production possibility frontier with pure public intermediate goods some recent studies have shown that certain forms of production functions satisfy the convexity of the production set in the presence of pure public intermediate goods this note permits a broader form of the production functions to reach the same result and further investigates the condition for the production surface to contain a flat portion une note sur la frontiere des possibilites de production quand des biens intermediaires sont purement publics certaines etudes recentes ont montre qu il existe certaines formes de fonctions de production susceptibles d assurer la convexite du bloc des possibilites de production quand existent des biens intermediaires purement publics cette note developpe certaines conditions plus generales des fonctions de production qui assurent le meme resultat de plus les auteurs examinent a quelles conditions le bloc des possibilites de production va avoir une portion plate

on data a case study of the evolution of income inequality across time and across countries this paper takes income distribution as a case study of the role of data in economics after describing the transformation which has taken place with regard to the availability of data on income inequality it discusses how the comparability of these estimates is brought into question by differences in methodology that cannot be eliminated by simple adjustments recent analyses of the relationships between income inequality and growth or globalisation are shown to be based on time series plagued by discontinuities which can seriously affect regression results the paper concludes by calling for greater attention to data quality in applied economics

methods of household consumption measurement through surveys experimental results from tanzania consumption expenditure has long been the preferred measure of household living standards however accurate measurement is a challenge and household expenditure surveys vary widely across many dimensions including the level of reporting the length of the reference period and the degree of commodity detail these variations occur both across countries and also over time within countries there is little current understanding of the implications of such changes for spatially and temporally consistent measurement of household consumption and poverty a field experiment in tanzania tests eight alternative methods to measure household consumption on a sample of 4 000 households there are significant differences between consumption reported by the benchmark personal diary and other diary and recall formats under reporting is particularly relevant in illiterate households and for urban respondents completing household diaries recall modules measure lower consumption than a personal diary with larger gaps among poorer households and households with more adult members variations in reporting accuracy by household characteristics are also discussed and differences in measured poverty as a result of survey design are explored the study concludes with recommendations for methods of survey based consumption measurement in low income countries

a meta analysis of the export growth hypothesis abstract meta analysis is performed on a sample of seventy six studies that have empirically gauged the nexus between exports and economic growth the results show that studies that use aggregate exports report lower t ratios but studies that use oil and manufactured exports report higher t ratios the study also documents the existence of publication bias in the literature

the optimal revenue tariff for public input provision abstract the revenue motive has been important in most countries employment of tariffs many ldcs remain dependent on the tariff as a revenue source such revenue may fund economic development projects that enhance domestic production possibilities as such these projects are better described as public inputs rather than public goods this paper derives efficiency rules for public input provision when the tariff is the sole source of revenue the implications of both private and public sector production of the public input are investigated in the latter case deviation from production efficiency is potentially welfare improving

revisiting the effects of imf programs on poverty and inequality investigating how lending programs of the international monetary fund imf affect poverty and inequality we explicitly address model uncertainty we control for endogenous selection into imf programs using data on 86 low and middle income countries for the 1982 2009 period and analyze program effects on various poverty and inequality measures the results rely on averaging over 90 specifications of treatment effect models and indicate adverse short run effects of imf agreements on poverty and inequality for the whole sample while for a 2000 2009 subsample the results are reversed there is evidence that significant short run effects might disappear in the long run author s abstract

income distribution political instability and investment abstract this paper successfully tests on a sample of 71 countries for the period 1960 85 the following hypotheses income inequality by fuelling social discontent increases sociopolitical instability the latter by creating uncertainty in the politico economic environment reduces investment as a consequence income inequality and investment are inversely related since investment is a primary engine of growth this paper identifies a channel for an inverse relationship between income inequality and growth we measure socio political instability with indices which capture the occurrence of more or less violent phenomena of political unrest and we test our hypotheses by estimating a two equation model in which the endogenous variables are investment and an index of socio political instability our results are robust to sensitivity analysis on the specification of the model and the measure of political instability and are unchanged when the model is estimated using robust regression techniques

cross country evidence on the distributional impact of fiscal policy abstractthis article provides new evidence on the distributional effects of fiscal policy using data on a panel of oecd economies over the last four decades we study how four measures of income in

stature and the standard of living research on the standard of living now emphasizes alternatives or supplements to the national income accounts this paper reviews the results of two decades of research using stature as a measure of health aspects of human welfare after comparing and contrasting stature with per capita income i consider height patterns discovered by economic historians that challenge traditional beliefs about the past including long term trends cycles in heights and the dreadfully small stature of slave children that was followed by catch up growth the paper concludes with comparisons to work in development economics and suggestions for research

democracy economic development and income inequality most cross national tests of inverse association between democracy and inequality have operationalized the concept of democracy by measuring its level at a single point in time more compelling theoretical arguments can be made for causal relationships that operate over time between 1 a country s years of democratic experience and income inequality and 2 income inequality and the stability of democracy continuous and qualitative measures of years of democratic experience are estimated to have a significant negative impact on income inequality independent of economic development and other control variables for a sample of 55 countries a very strong inverse correlation is also observed between income inequality and regime stability for a sample of 33 democracies this association holds independent of economic development which is found to have no direct effect on democratic stability after controlling for income inequality

natural resource booms and inequality theory and evidence we develop a theory in the context of a two sector growth model in which learning by doing drives growth to explain the time path of income inequality following natural resource booms in resource rich countries under the condition of a relatively unskilled labor intensive non traded sector inequality falls immediately after a boom and then increases steadily over time until the initial impact of the boom disappears using data for 90 countries between 1965 and 1999 we find evidence in support of the theory especially for oil and mineral booms we also find that uncertainty about future commodity prices increases long run inequality

production possibilities with a public intermediate good this paper considers the shape of the production possibility set with a public intermediate good of the atmos phere type the elements which tend to give rise to a concave product ion frontier are isolated from those which tend to generate a convex one by using the notion of the production surface the results from earlier models are both generalized and sharpened

equivalence scale relativities and the extent of inequality and poverty most inequality and poverty theory analyzes equivalent income distributions for homogeneous populations incomes are assumed to be deflated by an equivalence scale that accounts for differences in needs between households yet in practice there is no consensus about what the appropriate equivalence scale is the authors analyze how the choice of equivalence scale affects inequality and poverty measures and show that there is a systematic relationship between equivalence scale generosity and the extent of inequality and poverty they consider most of the measures in common use and provide some empirical illustrations copyright 1992 by royal economic society

new ways of looking at old issues inequality and growth abstract the paper uses new cross country data on income and asset land distribution to show that i there is a strong negative relationship between initial inequality in the asset distribution and long term growth ii inequality reduces income growth for the poor but not for the rich and iii available longitudinal data provide little support for the kuznets hypothesis policies that increase aggregate investment and facilitate acquisition of assets by the poor might thus be doubly beneficial for growth and poverty reduction

explaining import quality the role of the income distribution abstract we examine a generalized version of flam and helpman flam h helpman e 1987 vertical product differentiation and north south trade american economic review 77 810 822 in which consumption prices for quality differentiated goods are rising in household income we provide propositions for aggregating this relationship across heterogenous households to map cross country differences in income distributions to cross country differences in import price distributions the theoretical predictions are examined and confirmed using disaggregated data on prices of traded goods and micro data on household income from the luxemburg income study country pairs with more similar income distributions have more similar import price distributions whether similarity is measured by 1st 4th moment statistics population and consumption shares within world income and product price quantiles or income and price dis similarity indices

growth still is good for the poor incomes in the poorest two quintiles on average increase at the same rate as overall average incomes this is because in a global dataset spanning 118 countries over the past four decades changes in the share of income of the poorest quintiles are generally small and uncorrelated with changes in average income the variation in changes in quintile shares is also small relative to the variation in growth in average incomes implying that the latter accounts for most of the variation in income growth in the poorest quintiles these findings hold across most regions and time periods and when conditioning on a variety of country level factors that may matter for growth and inequality changes this evidence confirms the central importance of economic growth for poverty reduction and illustrates the difficulty of identifying specific macroeconomic policies that are significantly associated with the relative growth rates of those in the poorest quintiles

the circular relationship between inequality leverage and financial crises in this paper we put into perspective the recent literature which points to inequality as a possible cause of credit bubbles by reintegrating it into a more general analysis on the two way relationship between inequality and finance we focus more specifically on situations where high inequalities and widespread access to credit coexist and argue that even when institutions maintain more or less equal access to finance there may be a dynamic positive circular relationship between inequality and financial development however even if there is some evidence in the literature of a positive causal impact of inequality on credit this does not preclude other important cofounding factors the conclusions concerning the distributional impact of finance are more ambiguous a survey of the empirical literature highlights several issues that must be tackled first endogeneity reverse causality and coincidental factors are major concerns second the choice of consistent measurements for the key variables both credit and inequality has strong empirical implications and must be grounded on relevant theoretical channels third those circular dynamics have substantial policy implications for emerging economies since an increasing number face a joint increase in inequality and credit

economic inequality in the arab region the paper uses harmonized household survey micro data to assess the levels and determinants of economic inequality in 12 arab countries it focuses on the sources of rural urban as well as metropolitan nonmetropolitan inequalities and applies the unconditional quantile regression decomposition technique to analyze the welfare gaps across the entire distribution the analysis finds moderate inequality levels with the gini coefficient for the distribution of household real per capita total expenditures ranging between 30 7 in libya and 45 in mauritania differences in households endowments such as demographic composition human capital and community characteristics appear as the main sources of the urban rural welfare gap there is inequality between metropolitan and non metropolitan regions in many countries mainly because of differences in returns to households characteristics and particularly returns to human capital

infant mortality relative income and public policy do health outcomes depend on relative income as well as on an individual s absolute level of income we use infant mortality as a health status indicator and find a significant and positive link between infant mortality and income inequality using cross national data for 93 countries holding constant the income of each of the three poorest quintiles of a country s population we find that an increase in the income of the upper 20 of the income distribution is associated with higher not the lower infant mortality our results are robust and not just caused by the concave relationship between income and health the estimates imply a decrease in infant mortality by 1 5 for a one percentage point decrease in the income share of the richest quintile the overall results are sensitive to public policy public health care expenditure educational outcomes and access to basic sanitation and safe water can explain the inequality health relationship thus our findings support the hypothesis of public disinves

social welfare when needs differ an axiomatic approach if the social welfare of households of different demographic type has to be evaluated we observe considerable disagreement about the way the composition of households is to be taken into account this paper makes an attempt to differentiate some of the various approaches it deals with four methods in order to make their normative content transparent an axiomatic approach is employed the methods are completely characterized and some of their implications are demonstrated

inequality and democracy why inequality harms consolidation but does not affect democratization under what conditions do democracies emerge and consolidate recent theories suggest that inequality is among the leading determinants of both democratization and consolidation by contrast this article argues that inequality harms consolidation but has no net effect on democratization the author shows that the existing theories that link inequality to democratization suffer from serious limitations 1 they are useful only for understanding transitions from below and thus do not apply to many other transitions that is those from above 2 even for democratization from below their predictions are unlikely to hold since inequality actually has two opposite effects and 3 they ignore collective action problems which reduces their explanatory power however these objections do not affect the relationship between inequality and consolidation in particular while inequality has two opposite effects on the probability of transition to democracy it unambiguously increases the probability of transition away from democracy this article conducts the most comprehensive empirical test to date of the relationship between inequality and democracy it finds no support for the main democratization theories contrary to what they predict estimation suggests neither a monotonic negative nor an inverted u shaped relationship yet inequality increases the probability of backsliding from democracy to dictatorship

a new data set measuring income inequality this article presents a new data set on inequality in the distribution of income the authors explain the criteria they applied in selecting data on gini coefficients and on individual quintile groups income shares comparison of the new data set with existing compilations reveals that the data assembled here represent an improvement in quality and a significant expansion in coverage although differences in the definition of the underlying data might still affect inter temporal and international comparability based on this new data set the authors do not find a systematic link between growth and changes in aggregate inequality they do find a strong positive relationship between growth and reduction of poverty

income distribution and investment abstract after being the subject of a heated debate during the sixties and the seventies the relation between income distribution and growth has received renewed attention in recent years the new literature has focused on three channels whereby this relation can occur imperfections in capital markets voting on fiscal policy and political instability in all these approaches growth in or outside the steady state is the result of investment in physical or human capital therefore these theories can also be stated and tested in terms of the effects of income distribution on investment this has the double advantage of reducing the complexity of a necessarily brief survey and of bringing out more clearly the main elements of novelty in this literature so far empirical implementations of these theories have in general been restricted to reduced form regressions of growth or equivalently investment on income distribution and other variables in this survey i take a step further and test the three approaches by explicitly estimating the role of the imperfections in capital markets of government expenditure and of political instability in mediating the effects of income distribution on investment

does aid affect inequality we show that there was a negative correlation between pro poor aid and inequality in the period before the mid 2000s this article provides an explanation for this observed relationship using pane

income distribution factor endowments and trade openness abstract this paper studies the empirical links among factor endowments trade and personal income distribution by using panel data we show that land and capital intensive countries have a less equal income distribution while skill intensive countries have a more equal income distribution we also show that the effects of trade openness on inequality depend on factor endowments in a way consistent with several recent case studies but not with the simple hecksher ohlin framework our results are robust to the division of the sample according to level of income the inclusion of different regressors the use of different measures of trade openness and of relative factor abundance and tests for possible problems of endogeneity

promise and pitfalls in the use of secondary data sets income inequality in oecd countries as a case study this paper examines the role of secondary data sets in empirical economic research taking the field of income distribution as a case study we illustrate problems faced by users of secondary statistics showing how both cross country comparisons and time series analysis can depend sensitively on the choice of data after describing the genealogy of secondary data sets on income inequality we consider the main methodological issues and discuss their implications for comparisons of income inequality across oecd countries and over time the lessons to be drawn for the construction and use of secondary data sets are summarized at the end of the paper

is income inequality harmful for regional growth evidence from the european union this article examines the relationship between income inequality and economic growth in the regions of several european union countries over the period 1993 2002 using the information provided by the european community household panel taking into consideration the relevance of spatial effects in this context different versions of a spatial econometric model are estimated the results indicate that the degree of income dispersion is negatively associated with regional growth this finding is in fact robust to various alternative specifications including a number of additional explanatory variables such as initial per capita gdp the sectoral composition of economic activity human capital stock population density and market potential furthermore the observed negative correlation between income inequality and economic performance does not depend on the specific measure used to quantify the degree of income dispersion

the global concentration of wealth this paper compares changes in relative and absolute wealth concentrations to establish whether both processes have followed similar trajectories the findings indicate that while the relative wealth concentration level has increased in recent times it is not extraordinarily high from a historical perspective in contrast the absolute wealth concentration level is most likely higher than has ever previously occurred due to the growth of per capita wealth holdings and the population size of high net worth individuals hnwis the available data also suggest that hnwis recovered very quickly from the losses that they experienced in the financial crisis of 2008 as a result hnwis wealth holdings in 2013 were at least 30 higher than they were in 2007 the post crisis recovery of billionaires was even stronger with their 2014 net wealth holdings more than 85 higher than 2007 levels

macroeconomic performance and poverty in brazil abstract drawing on brazilian time series data this study finds an inelastic link between poverty and wages over the macroeconomic cycle that is devoid of the asymmetric effects that characterise the phenomenon s response to changes in the rate of unemployment deepening of structural reforms in the second half of the 1990s had no effect on the aforementioned relationships which also varied little by regional level of development finally the connection between poverty and long term income changes was more elastic suggesting an association between the economy s recent disappointing performance in alleviating poverty and its lacklustre growth record over the past two decades

inequality and growth uncovering the main conclusions from the empirics abstractthis paper is a critical survey of the empirical literature on the effects of inequality on economic growth we conclude that it is most likely that the disparities found in the results are due to differences in the type of countries and time periods included in the samples the variable used to measure inequality the structure of the data and the estimation techniques these findings suggest that the mechanisms that link inequality to growth are likely to operate differently in different circumstances an element that may offer important guidelines for both policy makers and researchers

inequality does cause underdevelopment insights from a new instrument consistent with the provocative hypothesis of engerman and sokoloff 1997 2000 this paper confirms with cross country data that agricultural endowments predict inequality and inequality predicts development the use of agricultural endowments specifically the abundance of land suitable for growing wheat relative to that suitable for growing sugarcane as an instrument for inequality is this paper s approach to problems of measurement and endogeneity of inequality the paper finds inequality also affects other development outcomes institutions and schooling which the literature has emphasized as mechanisms by which higher inequality lowers per capita income it tests the inequality hypothesis for development institutional quality and schooling against other recent hypotheses in the literature while finding some evidence consistent with other development fundamentals the paper finds high inequality to independently be a large and statistically significant barrier to prosperity good quality institutions and high schooling

immigrant selectivity and wages the evidence for women in an effort to extend the analysis of selectivity to female immigrants this paper examines the impact of economic conditions at the time of migration on the subsequent wages of foreign born women in the united states in addition the variables chosen to describe the migration decision have been expanded to include the effects of household status and immigration policy these results are compared to previous results for men and provide additional evidence about how the context of the migration decision affects the subsequent success of immigrants in the united states the sample for this project comes from the april 1983 current population survey and consists of married native and foreign born women between the ages of 16 and 64 excerpt

world welfare is rising estimation using nonparametric bounds on welfare measures abstract i take a new approach to measuring world inequality and welfare over time by constructing robust bounds for these series instead of imposing parametric assumptions to compute point estimates i derive sharp bounds on the atkinson inequality index that are valid for any underlying distribution of income conditional on given fractile shares and gini coefficients while the bounds are too wide to reject the hypothesis that world inequality may have risen i show that world welfare rose unambiguously between 1970 and 2006 this conclusion is valid for alternative methods of dealing with countries and years with missing surveys alternative survey harmonization procedures alternative gdp series or if the inequality surveys used systematically underreport the income of the very rich or suffer from nonresponse bias

halving global poverty the goal of central importance to this paper is to cut in half the proportion of people living below 1 a day from around 30 percent of the developing world s population in 1990 to 15 percent by 2015 based on population projections in 1990 this would correspond to around one billion people exiting poverty this paper begins by discussing poverty trends on a global scale where the poor are located in the world and how their numbers have been changing over time it then discusses the relationship of economic growth and income distribution to poverty reduction finally it suggests an evidence based agenda for poverty reduction in the developing world full text available at official url

growth distribution and politics we start by arguing that to understand growth differences across countries and time one needs to understand differences in public policies that affect the incentives for productive accumulation of capital human capital or technically useful knowledge and to understand policy differences one needs to understand how political institutions aggregate conflicting interests into public policies we then survey some recent work along these lines which argues that more inequality leads to slower growth next we illustrate some of the basic ideas of this work by help of a simple model of taxation we also present some econometric cross country evidence which is largely supportive of the basic ideas we end by suggestions for further work this abstract was borrowed from another version of this item

income distribution and development some stylized facts in recent years the relationship between income distribution and the process of development has come under increasing scrutiny much of the debate has focused on the hypothesis originally advanced by simon kuznets that the secular behavior of inequality follows an inverted u shaped pattern with inequality first increasing and then decreasing with development this hypothesis has become so much a part of the conventional wisdom on this subject that it has generated considerable skepticism about the welfare implications of the development process indeed on some interpretations developing countries face the grim prospect not just of increasing relative inequality but also of declining absolute incomes for the lower income groups

income distribution and infant mortality comparing two countries in which the poor have equal real incomes the one in which the rich are wealthier is likely to have a higher infant mortality rate this anomalous result does not appear to spring from measurement error in estimating the income of the poor and the association between high infant mortality and income inequality is still present after controlling for other factors such as education medical personnel and fertility the positive association of infant mortality and the income of the rich suggests that measured real incomes may be a poor measure of social welfare this paper considers and tests several possible explanations such as the provision of medical services the degree of urbanization the extent of female literacy and differences in the composition of births among different income groups none of these factors adequately accounts for the positive association between the incomes of the rich and infant mortality the geographical scope is worldwide excerpt

public investment optimal provision of hicksian public inputs a considerable portion of government spending is devoted to commodities that are not public goods but that directly affect production possibilities examples include public infrastructure like roads and dams educational facilities and research projects in basic science and some forms of information such commodities are public inputs in a small open economy context the focus of this paper is on those that are hicksian in nature an interesting decomposition of the beneficial impact of a hicksian public input is developed then first best and second best optimality conditions for public inputs that are comparable to those for collective consumption goods are derived

income distribution development and foreign trade a cross sectional analysis abstract this paper analyses cross sectional evidence on income inequality in developing countries within a consistent theoretical framework where the major explanatory variables are factor endowments their ownership structure and foreign trade distortions the resulting explanation of cross country differences in income distribution is considerably better than what is found in the existing literature endowments in mineral resources land concentration in agricultural exports trade protection and secondary schooling are shown to be major determinants of differences in income inequality across developing countries

the medium run effects of educational expansion evidence from a large school construction program in indonesia this paper studies the medium run consequences of an increase in the rate of accumulation of human capital in a developing country from 1974 to 1978 the indonesian government built over 61 000 primary schools the school construction program led to an increase in education among individuals who were young enough to attend primary school after 1974 but not among the older cohorts 2sls estimates suggest that an increase of 10 percentage points in the proportion of primary school graduates in the labor force reduced the wages of the older cohorts by 3 8 10 and increased their formal labor force participation by 4 7 i propose a two sector model as a framework to interpret these findings the results suggest that physical capital did not adjust to the faster increase in human capital

distributive politics and economic growth a crude distinction between economics and politics would be that economics is concerned with expanding the pie while politics is about distributing it in this paper we analyze the relationship between the two we focus on how an economy s initial configuration of resources shapes the political struggle for income and wealth distribution and how that in turn affects long run growth our main conclusion is that inequality is conducive to the adoption of growth retarding policies we derive this result from a simple political economy model of growth and present cross country evidence consistent with it the key feature of our model is that individuals differ in their relative factor endowments we distinguish between two types of factors an accumulated factor called capital and a nonaccumulated factor called labor growth is driven by the expansion of the capital stock which is in turn determined by individual saving decisions long run growth is endogenous as the aggregate production function is taken to be linearly homogeneous in capital and productive government services taken together the provision of government services is financed by a tax on capital because government services are productive a small tax on

political rights and income inequality a cross national test among contemporary nations the relationship between income equality and national wealth exhibits an inverted u shape low among the richest and poorest nations and high for nations with intermediate wealth to examine the reasons for this relationship i hypothesize that both political democracy and educational enrollment are related in a similar way to income inequality two data sets are used in this analysis modified version of muller s set of 62 nations circa 1965 1975 and hoover s data set multiple regression reveals that measures of political democracy and the educational enrollment levels have an inverted u relationship with income inequality national wealth gnp had no consistent direct effect on income inequality a satisfactory specification of national levels of income inequality must include the polynomial functions of political democracy and education

data watch the world bank s living standards measurement study household surveys since 1985 the world bank has been collecting household survey data in developing countries that provide a rich source of information for assessing household welfare understanding household behavior and evaluating the impact of government policies this article describes these household surveys known as living standards measurement study lsms surveys and explains how to obtain their data lsms surveys have been implemented in over twenty developing countries and have been used to analyze poverty labor markets health and education pricing policies determinants of school performance savings and consumption smoothing health and nutrition policies and gender and fertility issues

economic globalization domestic politics and income inequality in the developed countries a cross national study this article assesses the impact of economic globalization and domestic political factors on income inequality and state redistribution in the developed countries over the past two decades using household level data from the luxembourg income study that are more detailed accurate and cross nationally comparable than those used in previous empirical work it examines three major modes of international integration trade direct foreign investment and international financial flows as well as four domestic political variables the partisan balance of national cabinets electoral turnout union density and the centralization of wage setting institutions the study finds only scattered relationships between global integration and income distribution or redistribution but reasonably strong positive relationships between several domestic political variables and an egalitarian distribution of income and or extensive state redistribution these findings are consistent with a growing number of studies that emphasize the resilience of domestic political factors in the face of economic globalization

recent trends in top income shares in the usa reconciling estimates from march cps and irs tax return data although the majority of research on us income inequality trends is based on public use march cps data a new wave of research using irs tax return data reports substantially higher levels of inequality and faster growing trends we show that these apparently inconsistent estimates are largely reconciled if the inequality measure and the income distribution are defined in the same way using internal cps data for 1967 2006 we closely match irs data based estimates of top income shares reported by piketty and saez 2003 our results imply that any inequality increases since 1993 are concentrated among the top 1 percent of the distribution

inequality and institutions abstract this paper presents theory and evidence on the relationship between inequality and institutional quality we exhibit a model in which the two may dynamically reinforce each other and set to test this relationship with a broad array of institutional measures the double causality between institutional strength and a more equal distribution of income is empirically established using dynamic panel and linear feedback analysis

education growth and income inequality estimates of the effect of education on gdp the social return have been hard to reconcile with micro evidence on the private return to schooling we present a simple explanation combining two ideas imperfect substitution and endogenous skill biased technological progress and use cross country panel data on inequality and gdp to test these ideas a one year increase in the level of education reduces the private return by 2 percentage points consistent with katz murphy s 1992 elasticity of substitution we find no evidence for reversal of this initial effect as in acemoglu 2002 in the short run the social return equals the private return

explaining international and intertemporal variations in income inequality this paper explores the propositions that income inequality is relatively stable within countries and that it varies significantly among countries a new and expanded data set provides broad support for both propositions drawing on a political economy and capital market imperfection arguments to explain the intertemporal and international variation in inequality the empirical analysis shows that the predicted variables associated with the first argument a measure of civil liberties and the initial level of secondary schooling and the second argument a measure of financial depth and the initial distribution of land are indeed important determinants of inequality this paper explores two propositions regarding income inequality they are first income inequality is relatively stable within countries and second it varies significantly across countries to illustrate note that the gini coefficient in india remained almost constant for forty years 1951 92 with mean 32 6 and standard deviation 2 0 2 in contrast the variation in gini coefficients across countries is large 61 9 in honduras in 1968 compared with 17 8 in bulgaria in 1976 if substantiated these propositions have potentially significant implications for poverty the significance of the first is obvious barring any fundamental socio political change poverty reduction will depend crucially on the rate of economic growth given this the significance of the second is that in inegalitarian economies the poor will enjoy a smaller share of any national increment in income than in more egalitarian ones drawing on a new and expanded data set on inequality deininger and squire 1996a the first of the paper s three sections conducts standard statistical tests of the two propositions the sample comprises 573 observations on the most common measure of inequality the gini coefficient for 49 developed and developing countries covering the period 1947 94 the results broadly confirm our two propositions specifically analysis of variance anova shows that about 90 of the total variance in the gini coefficients
