human capital and inequality dynamics the role of education technology the paper offers a unified way to examine several puzzles on inequality dynamics it focuses on differences in the education technology and their effects on income distributions our overlapping generations economy has the following features 1 consumers are heterogenous with respect to ability and parental human capital and 2 intergenerational transfers take place via parental direct investment in education and public education financed by taxes possibly with a level determined by majority voting we explore several variations in the production of human capital some attributed to home education and others related to public education and indicate how various changes in education technologies affect the intragenerational income inequality along the equilibrium path

top income shares in oecd countries the role of government ideology and globalisation this paper investigates how government ideology and globalisation are associated with top income shares in 17 oecd countries over the period 1970 to 2014 we use top income shares of the world wealth and income database wid globalisation is measured by the kof index of globalisation static and dynamic panel model results show that the top income shares increased more under right wing governments than under left wing governments the ideology induced effect was stronger when globalisation proceeded more rapidly globalisation was positively correlated with income shares of the upper middle class p99 p90 but negatively with income shares of the rich top 1 in the overall sample we show that the relationship differs between anglo saxon countries and other oecd countries globalisation was more pro rich in anglo saxon countries than in other oecd countries government ideology does not turn out to have a statistically significant effect on top income shares in anglo saxon countries after the 1980s whereas ideology induced differences in the distributional outcomes continued in other oecd countries

openness and wage inequality in developing countries the latin american challenge to east asian conventional wisdom the experience of east asia in the 1960s and 1970s supports the theory that greater openness to trade tends to narrow the wage gap between skilled and unskilled workers in developing countries in latin america since the mid 1980s however increased openness has widened wage differentials this conflict of evidence is probably not the result of differences between east asia and latin america instead the conflict is probably the result of differences between the 1960s and the 1980s specifically the entry of china into the world market and perhaps the advent of new technology biased against unskilled workers

optimal contracting with dynastic altruism family size and per capita consumption we use a barro becker model of endogenous fertility in which parents are subject to idiosyncratic shocks that are private information either to labor productivity or taste for leisure to study the efficient degree of consumption inequality in the long run the planner uses the trade off between family size and future consumption and leisure to provide incentives for workers to reveal their shocks we show that in this environment the optimal dynamic contract no longer features immiseration in consumption we also discuss the implications of the model on the long run properties of family size in the optimal contract and show that the long run trend in dynasty size can be either positive or negative depending on parameters

natural resources and income inequality the role of ethnic divisions we hypothesize that natural resources raise income inequality in ethnically polarized societies but reduce income inequality in ethnically homogenous societies and we present empirical evidence in support of this hypothesis

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

how much are people willing to pay for silence a contingent valuation study despite its major importance in the urban environment the problem of noise has received little attention from environmental economists in this paper the economic value of a noise reduction programme is evaluated the chosen technique is contingent valuation using the recently proposed one and one half bound question format this new question format reduces the potential for response bias in multiple bound formats such as the double bound model while maintaining much of its efficiency through the estimations it is found that urban residents generally value noise negatively that is households are willing to pay for a noise reduction in particular it is found that households are willing to pay approximately four euros per decibel per year a further finding is that interviewees show scope sensitivity that is households display a different willingness to pay for different degrees of noise reduction most are willing to pay more for larger decreases in the level of disturbance from noise

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

when is growth pro poor evidence from a panel of countries abstract growth is pro poor if the poverty measure of interest falls according to this definition there are three potential sources of pro poor growth a a high growth rate of average incomes b a high sensitivity of poverty to growth in average incomes and c a poverty reducing pattern of growth in relative incomes i empirically decompose changes in poverty in a sample of developing countries during the 1980s and 1990s into these three components in the medium to long run most of the variation in changes in poverty can be attributed to growth in average incomes suggesting that policies and institutions that promote broad based growth should be central to the pro poor growth agenda most of the remainder of the variation in changes in poverty is due to poverty reducing patterns of growth in relative incomes rather than differences in the sensitivity of poverty to growth in average incomes cross country evidence provides relatively little guidance as to the policies and institutions that promote these other sources of pro poor growth

opportunity and social mobility the fact that the children of rich parents have better economic prospects than the children of poor parents unequal opportunity is generally thought to be one of the weak points of modem capitalist societies the ability of the descendants of poor families to eventually become rich and the descendants of rich families to eventually become poor social mobility is commonly considered to be one of the strong points of these societies here i argue that both of these characteristics are in fact necessary implications of an efficient societal arrangement when incentives to work hard must be provided i argue this point using a generational version of the model of phelan and townsend 1991 an infinitely repeated general equilibrium economy with incentive constraints in my model each household s stochastic output is a function of its level of effort since effort is assumed to be costly and privately observed households can shirk higher than minimal effort levels must be induced by making a household s present or future consumption dependent on the household s observed output history a large literature considers models similar to this including green 1987 atkeson and lucas 1992 phelan 1994 1995 wang 1995 hopenhayn and nicolini 1997 khan and ravikumar 2002 the main difference between the economies in that literature and here is that here instead of a household consisting of a single infinitely lived individual a household consists of a sequence of altruistically linked individuals a familial dynasty each of whom lives for one period this difference affects the appropriate societal ranking of allocations when households consist of a single infinitely lived individual allocations can be ranked according to their implied distributions of ex ante lifetime utilities if one allocation delivers a distribution of ex ante utilities dominated by another allocation then the first allocation is inefficient however if a household consists of a sequence of altruistically linked individuals then the appropriate ranking of allocations is no longer obvious how those in the first generation rank allocations will in general differ from how their descendants rank allocations this paper addresses this conflict between generations by ranking allocations according to a rawlsian veil of ignorance criterion rawls 1971 that is here society seeks to maximize the expected dynastic utility utility including altruism toward descendants of an individual who does not know into which generation he will be born and the identity or output levels of his ancestors 1 i argue that this corresponds to a societal ranking which does

distributional consequences of globalisation empirical evidence from panel data abstract this paper investigates the impact of globalisation on cross country inequality using a large panel dataset the findings reveal that location and capital are the main determinants of inequality trade intensity and foreign direct investment make only a small contribution approximately 4 the relative contributions of trade and foreign direct investment to inequality have changed little over time and have certainly not increased at the same rate as the rise in global trade and investment activity hence globalisation does not emerge as a significant factor in driving cross country inequality differences emerge when countries are grouped by relative income but the main findings persist

efficiency and equality in a simple model of efficient unemployment insurance abstract this paper describes the efficient allocation of consumption and work effort in an economy in which workers face idiosyncratic employment risk and considerations of moral hazard prevent full insurance we impose a lower bound on the expected discounted utility that can be assigned to any agent from any date onward and show with this feature added that the efficient unemployment insurance scheme induces an invariant cross sectional distribution of individual entitlements to utility the paper thus provides a simple prototype model suited to the study of the normative question what is the trade off between equality and efficiency in resource allocation journal of economic literature classification numbers d31 d63 d82 j65

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

on the impact of financial development on income distribution time series evidence financial market development is said to have equalizing or unequalizing effects on income distribution previous research used cross sectional and panel data and provided mixed results suspecting that they suffer from aggregation bias we adhere to time series data and error correction modeling technique and address the issue one more time in each of the 17 countries for which we have time series data in 10 counties short run effects of financial market development on income distribution were found to be equalizing in five countries the effects were unequalizing however the equalizing effects lasted into the long run only in three countries of denmark kenya and turkey

the evolution of inequality after trade liberalization abstract the paper presents a general framework for the analysis of the evolution of personal income distribution following trade liberalization the model allows many factors of production and the possibility of capital gains in this framework the short run evolution of inequality depends on the wage to wealth ratio while changes in the interest rate determine the changes in long run inequality the general framework is applied to the dynamic specific factors model of eaton rev econ stud vliv 1987 in this model the land labor ratio determines whether a country exports the land using or the capital using good in the long run the type of the export good determines the effects of liberalization on inequality in land labor abundant countries inequalities increase decrease along the dynamic path the model provides an explanation for the differences between latin american and asian countries in their response to trade liberalization econometric analysis provides mixed results for these predictions with the correct signs but non significant coefficients for the coefficient on the interaction between openness and the land labor ratio

investment in education do economic volatility and credit constraints matter abstract recent research has focused on the effects of economic volatility on the investment in physical capital this paper shows that economic volatility and the lack of financial markets have a negative effect also on the accumulation of human capital our evidence drawn from cross country and panel regressions is that average secondary enrollment in the period 1970 1972 is negatively affected by the lack of financial markets income or employment volatility and income inequality our results are robust to different specifications of volatility the inclusion of public expenditure in education country specific effects and different sets of regressors

on efficient distribution with private information this paper is a study of the dynamics of the efficient distribution of consumption in an exchange economy with many consumers each of whom is subject to private idiosyncratic taste shocks we propose a recursive method for finding feasible allocations that are incentivecompatible and that are pareto optimal within this set the method is applied to several parametric examples we find that in an efficient allocation the degree of inequality continually increases with a diminishing fraction of the population receiving an increasing fraction of the resources we discuss the extent to which these allocations can be decentralized via market arrangements this paper is a study of the dynamics of the efficient distribution of consumption in an exchange economy with private information the economy we study has a constant endowment flow of a single non storable consumption good which is to be allocated each period among a large number of consumers each period these consumers experience unpredictable idiosyncratic privately observed taste shocks affecting their marginal utility of current consumption efficiency dictates that more resources be allocated to those consumers who in any given period have a high marginal utility of current consumption

the kuznets process and the inequality development relationship abstract in his classic paper on economic growth and income inequality kuznets discussed the process of population shift from traditional to modern activities as the basis for a theory of distributional change during the course of development in this paper we present a formalization of the kuznets process conduct a general analysis of distributional change under this process and derive the functional forms of and conditions for a turning point in the inequality development relationship for six commonly used indices of inequality the functional form appropriate to each index is then estimated using cross section data on 60 developing and developed countries finally some extensions to the initial formalization of the kuznets process are considered

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

how does trade openness influence budget deficits in developing countries abstract this paper analyses the effects of trade openness on budget balances by distinguishing the effects of natural openness from those of trade policy revealed indicators of natural openness and trade policy are computed using gmm system estimator the econometric analysis focuses on 66 developing countries over 1974 98 the results show that trade openness increases a country s exposure to external shocks this enforces the negative impact on budget balances of terms of trade instability additionally trade openness influences budget balances through several other channels corruption income inequalities etc then natural openness and trade policy have opposite effects the former deteriorates budget balances whereas the latter enhances them

economic policy changes and wage differentials in latin america abstract this article presents estimates of the impact of changes in liberalization policies on wage differentials by schooling level using a new high quality data set for 18 latin american countries for 1977 98 the method controls for all fixed and time varying country characteristics some of which may affect the policies themselves the results indicate that liberalizing policy changes overall have had a short run disequalizing effect of expanding wage differentials although this effect tends to fade away over time this disequalizing effect is due to the strong impact of domestic financial market reform capital account liberalization and tax reform however privatization contributed to narrowing wage differentials and increasing trade openness had no significant effect on wage differentials technological progress rather than trade flows appears to be a channel through which policy changes are affecting inequality

bringing income distribution in from the cold the title of this presidential address is chosen to highlight the way in which the subject of income distribution has in the past been marginalised for much of this century it has been very much out in the cold there are signs that in the 1990s it is being welcomed back and i shall be referring to recent research but i would like to use this occasion to give further impetus to the re incorporation of income distribution into the main body of economic analysis this abstract was borrowed from another version of this item

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

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

complements versus substitutes and trends in fertility choice in dynastic models demographers emphasize decreased mortality and economic development as the main contributors generating the demographic transition contrary to previous findings we show that simple dynastic models a la barro becker can reproduce observed changes in fertility in response to decreased mortality and increased productivity growth if the intertemporal elasticity of substitution is low enough we show that this is largely due to number and welfare of children being substitutes in the utility of parents in this case we find that with an ies of one third model predictions of changes in fertility amount to two thirds of those observed in u s data since 1800 between 1800 and 2000 fertility choice in the united states underwent a dramatic transition depending on estimates it fell from about six children per woman to around two children per woman this demographic transition from a state of high fertility and high mortality to low fertility and low mortality has been documented by demographers and historians in the united states and in every other developed country in the world over this same period natural rates of population growth net of immigration also fell but less substantially demographers have not reached a consensus on the root causes of this transformation but list several changes as likely main contributors these include reductions in infant and child mortality rates imrs and cmrs and the process of industrialization and economic development the work in demography and history on this topic has largely been limited to empirical studies with almost no choice based modeling of the type seen in economics even there issues of the timing of changes
