on the world economic elite economic elites have not received enough attention in the economic literature the obvious reason is limited access to information this paper seeks to contribute to contemporary knowledge on elites in two ways first it employs a new unique data set on the world economic elite covering 2002 2014 to develop a method of measuring the degree of elite circulation second it provides a theoretical explanation of the observed facts the empirical finding is that the world economic elite is subject to a low degree of circulation despite increased globalization liberalization longterm economic growth and the recent great recession the core of the elite remains mostly unchanged our theory attempts to explain this fact by introducing the analytical distinction between market competition and elite competition which is a kind of meta competition thus the following relationship is derived from the theory the low level of elite circulation that is the low meta competition underlies the oligopolistic market structures that we observe in the real world

homeownership and economic performance of immigrants in germany this paper investigates the homeownership gap between native and immigrant households in germany paying particular attention to the assimilation process of immigrant households a double cohort model is derived which circumvents the identification problem for separating age period and cohort effects and accounts for differences in the effects the empirical findings suggest that immigrant households are less likely to own their primary residence than comparable native households moreover the duration of residence in germany does not affect the homeownership probability of immigrants indicating that an assimilation process in homeownership between native and immigrant households did not take place this result is largely consistent with the german immigration policy which has focused predominantly on short run economic needs and has neglected long run economic effects of immigration

rational heuristics expectations and behaviors in evolving economies with heterogeneous interacting agents we analyze the individual and macroeconomic impacts of heterogeneous expectations and action rules within an agent based model populated by heterogeneous interacting firms agents have to cope with a complex evolving economy characterized by deep uncertainty resulting from technical change imperfect information coordination hurdles and structural breaks in these circumstances we find that neither individual nor macroeconomic dynamics improve when agents replace myopic expectations with less naive learning rules our results suggest that fast and frugal robust heuristics may not be a second best option but rather rational responses in complex and changing macroeconomic environments jel c63 d8 e32 e6 o4

women don t run election aversion and candidate entry to study gender differences in candidate emergence we conduct a laboratory experiment in which we control the incentives potential candidates face manipulate features of the electoral environment and measure beliefs and preferences we find that men and women are equally likely to volunteer when the representative is chosen randomly but that women are less likely to become candidates when the representative is chosen by an election this difference does not arise from disparities in abilities risk aversion or beliefs but rather from the specific competitive and strategic context of campaigns and elections thus we find evidence that women are election averse whereas men are not election aversion persists with variations in the electoral environment disappearing only when campaigns are both costless and completely truthful

portfolio choices of parents and their children as young adults asset accumulation by african american families the portfolio composition decision often is stylized as either a life cycle choice to allocate income to consumption or as a choice along a risk return locus with the locus derived from the underlying market equilibrium of asset returns and prices empirical work on household financial behavior has identified large differences in wealth levels and in portfoliocomposition choices of different demographic groups well beyond income and risk tolerance by far the most striking difference in this literature emerges when the population is subdivided by race for example given the strong performance of the u s equity market in the past decade portfolio choices of stocks have been key to wealth building yet africanamerican families have been less likely to have held stocks as of the mid 1980 s and less likely to have become shareholders over the period 1989 1994 erik hurst et al 1998 this paper attempts to resolve this puzzle by examining cross generational influences on current portfolio composition decisions

growth income inequality and fiscal policy what are the relevant trade offs we develop an endogenous growth model with elastic labor supply in which agents differ in their initial endowments of physical capital in this context the growth rate and the distribution of income are jointly determined we then examine the distributional impact of different ways of financing an investment subsidy policies aimed at increasing the growth rate result in a more unequal distribution of pre tax income consistent with the positive correlation between income inequality and growth observed in the recent empirical literature however there is no conflict between efficiency and equity if inequality is measured in terms of the distribution of welfare

effects of patent policy on income and consumption inequality in a r d growth model what are the effects of strengthening patent protection on income and consumption inequality to analyze this question this paper incorporates heterogeneity in the initial wealth of households into a canonical quality ladder growth model with endogenous labor supply in this model i firstly show that the aggregate economy always jumps immediately to a unique and stable balanced growth path given the balanced growth behavior of the aggregate economy and an exogenous distribution of initial wealth i then show that the endogenous distribution of assets in subsequent periods is stationary and equal to its initial distribution the model predicts that strengthening patent protection increases a economic growth by stimulating r d investment and b income inequality by raising the return on assets however whether it also increases consumption inequality depends on the elasticity of intertemporal substitution if and only if this elasticity is less greater than unity strengthening patent protection increases decreases consumption inequality for standard parameter values strengthening patent protection leads to a larger increase in income inequality than consumption inequality

fiscal and monetary policies in complex evolving economies what is the most appropriate combination of fiscal and monetary policies in economies subject to banking crises and deep recessions we study this issue using an agent based model that is able to reproduce a wide array of macro and micro empirical regularities simulation results suggest that policy mixes associating unconstrained counter cyclical fiscal policy and monetary policy targeting employment is required to stabilise the economy we also show that discipline guided fiscal rules can be self defeating as they depress the economy without improving public finances finally we find that the effects of monetary and fiscal policies become sharper as the level of income inequality increases

measuring the distribution of material well being u s trends abstract economists with a few exceptions have automatically assumed that the important measure of well being is income in contrast economic historians have broadened the measure of well being with particular interest in mortality morbidity nutrition education and leisure when one takes this broader view of the standard of living there appears to be a strong trend toward more equality in the distribution of well being since the industrial revolution gini coefficients calculated for the distributions of lifespan and educational attainment have declined dramatically since the mid nineteenth century for the united states mortality and educational differentials have also declined inequality of leisure time and consumption though not as consistently measured also show trends toward equality over the twentieth century these trends toward equality in well being as measured by indicators other than income and wealth seem to be generated by provision of public goods natural boundaries to lifespan educational attainment and leisure and by the growth in mean per capita income the divergent trends in the distributions of income and the other measures of well being caution against reliance on the distribution of income to interpret trends in inequality

a comparative analysis of the nativity wealth gap this paper investigates the source of the gap in the relative wealth posi tion of immigrant households residing in australia germany and the united states our results indicate that in germany and the united states wealth difierentials are largely the result of disparity in the educational attainment and demographic composition of the native and immigrant populations while income difierentials are relatively unimportant in understanding the nativity wealth gap in contrast the relatively small wealth gap between australian and foreign born households exists because immigrants to australia do not translate their relative educational and demographic advantage into a wealth advantage on balance our results point to substantial cross national disparity in the economic well being of immigrant and native families which is largely consistent with domestic labor markets and the selection policies used to shape the nature of the immigration ow

racial differences in patterns of wealth accumulation making use of psid data for 1984 1989 and 1994 we examine race differences in patterns of asset accumulation our results indicate as expected that inheritances raise the rate of wealth accumulation of whites relative to that of african americans but while whites devote a greater share of their income to saving racial differences in saving rates are not significant once we control for income though our results may be period specific we also do not find evidence that the rate of return to capital is greater for whites than for african americans simulations suggest that african americans would have gained significant ground relative to whites during the period if they had inherited similar amounts saved at the same rate had comparable income levels and more speculatively had portfolios closer in composition to those of whites

stock market wealth and consumption this paper explores the link between changes in the aggregate value of corporate stock and changes in consumer spending it presents data on the distribution of corporate stock ownership based on the 1998 survey of consumer finances it also uses time series evidence on the comovement of stock market wealth and various categories of consumer spending to calibrate the wealth effect it concludes that in the year after a change in stock market values consumer spending is likely to rise by between one and two cents for each dollar increase in the value of corporate stock

recent trends in the size distribution of household wealth based on the survey of consumer finances the distribution of wealth in the united states became much more unequal in the 1980s and that trend continued albeit at a slower pace in the 1990s the only households that saw their mean net worth rise in absolute terms between 1983 and 1995 were those in the top 20 percent and the gains were particularly strong for the top one percent all other groups were particularly strong for the top one percent all other groups suffered real wealth losses including the median household and declines were particularly precipitous at the bottom racial disparities widened and young households also lost out over this period

gender differences in wealth at retirement recent economic trends like the growing prevalence of defined contribution retirement plans have made individuals increasingly responsible for their own financial security financial security greatly depends on the ability to accumulate adequate wealth edward wolff 1998 wealth can be a significant source of retirement income for individuals less and less able to rely on social security and employerprovided defined benefit pension plans one concern in the current economic climate is the persistent gap in wealth between men and women several papers for example lucie schmidt and purvi sevak 2006 have found that the gap is significant even after controlling for individual characteristics this paper contributes to the literature by studying the role of risk preferences in addition to other characteristics specifically it addresses the following research question controlling for other factors do gender differences in risk preferences contribute to the gender wealth gap at retirement the underlying premise is that women are more risk averse than men which is supported by previous research for example robert b barsky et al 1997 a simple theoretical model of household decision making illustrates that retirement wealth is a function of income earned over the lifetime and risk aversion the model is empirically tested using data from the health and retirement study hrs 1 results show that the gender gap in wealth persists even when risk preferences are added to the set of controls thus the unexplained gap remains a cause for concern

monetary stabilisation with nominal asymmetries optimal monetary stabilisation in the standard new keynesian framework usually assumes a policy loss function from outside the model in this paper in contrast the objective arises directly from the model credit constraints and sticky nominal debt contracts imply that monetary stabilisation has asymmetric impacts depending on whether consumers are credit constrained the policy problem is to maximise some weighting of the expected utility of the different types of consumer features of optimal stabilisation are derived that do not appear to be far out of line with empirical evidence for many countries but that clearly conflict with standard loss function results

the savers spenders theory of fiscal policy the macroeconomic analysis of fiscal policy is usually based on one of two canonical models the barro ramsey model of infinitely lived families or the diamond samuelson model of overlapping generations this paper argues that neither model is satisfactory and suggests an alternative in the proposed model some consumers plan ahead for themselves and their descendants while others live paycheck to paycheck this model is easier to reconcile with the essential facts about consumer behavior and wealth accumulation and it yields some new and surprising conclusions about fiscal policy

car ownership and the labor market of ethnic minorities we show how initial wealth differences between low skilled minorities and white workers can generate differences in their labor market outcomes this even occurs in the absence of a taste for discrimination against ethnic minorities or exogenous differences in distance to jobs because of the initial wealth difference minorities cannot afford to buy a car while whites can car ownership allows whites to reach more jobs per unit of time which gives them a better bargaining position in the labor market as a result in equilibrium ethnic minorities end up with both higher unemployment rates and lower wages than whites furthermore we also show that it takes more time for minorities to reach their jobs even though they travel less miles when employed those predictions are consistent with the data better access to capital markets or better public transportation will reduce the differences in labor market outcomes

time preference and the importance of saving for retirement abstract this study models the importance respondents place on saving for retirement as a function of time preference using a sample of 6812 undergraduate and graduate students individual time preference is measured by comparing dollar values over time and through a combination of intertemporal behaviors that may be the most theoretically appropriate measurement of the discount rate for utility over time results show strong correlations among decision making domains that involve time discounting time preference measured by comparing dollar amounts across time proves a much weaker predictor than a combination of intertemporal behaviors measured either as a linear scale or as factors in multivariate models a factor of intertemporal preventive health behaviors is a stronger predictor of the importance of saving for retirement than all other explanatory variables including age race parental income gender gpa and college major

to defer or not defer uk state pension and work decisions in a lifecycle model the uk state pension which depends only on age includes an option to defer take up which yields either a subsequent lump sum or higher weekly pension we analyse the joint decisions on pension deferral and intertemporal labour supply participation in a lifecycle setting we show that deferral is purely a financial decision but the impact of deferral on work decisions depends on preferences wage rates non labour income and initial wealth to exactly characterize this we use a quasilinear utility function and provide calibrated simulations we also discuss the choice between a lump sum or increased weekly pension

second best optimal taxation of capital and labor in a developing economy abstract as commercial integration reduces the reliance on foreign trade taxation raising tax revenue has become a major concern for the governments of developing economies this paper examines how the tax burden in a developing economy should be distributed between capital income and labor income we study a two sector model where the traditional sector is informal and consequently cannot be taxed by the government in this setup we find that the optimal second best tax structure in order to raise a certain amount of revenue requires to tax capital income at least as much as labor income and possibly more

the wealth of mexican americans this paper analyzes the sources of disparities in the relative wealth position of mexican americans results reveal that unlike the racial wealth gap mexican americans wealth disadvantage is in large part not the result of differences in wealth distributions conditional on the underlying determinants of wealth rather mexican americans wealth disadvantage is attributable to the fact that these families have more young children and heads who are younger mexican americans low educational attainment also has a direct effect in producing a wealth gap relative to other ethnic groups even after differences in income are taken into account income differentials are important but do not play the primary role in explaining the gap in median net worth finally geographic concentration is generally unimportant but does contribute to narrowing the wealth gap between wealthy mexican americans and their white and black counterparts

the distribution of wealth with uncertain income it is well known that an uncertain income stream will induce individuals to save if they are forward looking in this paper we investigate the consequences of such saving on the distribution of wealth among households the inquiry is motivated by the fact that both the dispersion of the us wealth distribution and the variance of transitory income have increased in the recent past surprisingly we find that an increase in earnings uncertainty is more likely to decrease than increase the inequality in wealth holdings

black white differences in wealth and asset composition using data from the 1976 and 1978 national longitudinal surveys of young men and young women this study examines racial differences in the magnitude and composition of wealth and the reasons for them on average young black families hold 18 percent of the wealth of young white families and hold their wealth in proportionately different forms even after controlling for racial differences in income and other demographic factors as much as three quarters of the wealth gap remains unexplained we speculate on the causes for this concluding that racial differences in intergenerational transfers and to a lesser extent barriers to the accumulation of business and home equity most likely play a role

what is a fair co2 tax increase on fair emission reductions in the transport sector we examine how individual preferences for fair reductions of carbon dioxide co2 emissions affect the support for increases in the co2 tax on gasoline and diesel we assume that people not only care about their own material welfare but also have preferences for fairness in policy design and we explore the implications using original data from a mail questionnaire sent to a representative sample of the swedish population the main result is that fairness in policy design does matter those respondents who adhere to a fairness principle tend to be relatively more positive to increases in the co2 tax one possible explanation for this result is that there is a relatively high degree of reciprocity regarding the origin of emissions and the fairness regarding who should bear the burden of co2 reductions via a split sample analysis we also find that the relative importance of fairness principles is dependent upon whether one uses a car often or not this sheds light on the potential goal conflict between the importance of fairness principles and self interest in the form of a need for private car transportation

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

wealth information acquisition and portfolio choice i solve with an approximation a grossman stiglitz economy under general preferences thus allowing for wealth effects because information generates increasing returns decreasing absolute risk aversion in conjunction with the availability of costly information is sufficient to explain why wealthier households invest a larger fraction of their wealth in risky assets one no longer needs to resort to decreasing relative risk aversion an empirically questionable assumption furthermore i show how to distinguish empirically between these two explanations finally i find that the availability of costly information exacerbates wealth inequalities copyright 2004 oxford university press

estimation and impact of gender differences in risk tolerance i introduction are women systematically less risk tolerant than men the answer has critical implications for the financial well being of women schubert et al 1999 for example corporations may pass women over for promotion if it is believed that they are unable to make risky financial decisions johnson and powell 1994 financial advisers believing that women are less risk tolerant may recommend conservative portfolios that have lower returns wang 1994 this paper uses a simple model of individual portfolio choice to estimate the distributions of risk tolerance for women and men moments of the model are matched to data on individual retirement accounts iras from the health and retirement study hrs to obtain estimates of the distributions parameters under the assumption of constant relative risk aversion crra utility results show that the mean risk tolerance is 0 25 for women and 0 28 for men economists generally assume that risk aversion the reciprocal of risk tolerance falls in the 0 10 range jagannathan and kocherlakota 1996 the estimates obtained in this paper are consistent with this assumption the impact of the results is gauged in the context of gender differences in wealth accumulation less risk tolerant individuals are more conservative investors conservative investments can lead to low levels of wealth accumulation and may account for the gender gap in wealth lyons et al 2008 data on older americans from the hrs show that men have 103 more wealth in their iras than do women 1 the results from this paper show that gender differences in risk tolerance alone would lead to men accumulating 10 more wealth than women gender differences in risk tolerance can thus account for nearly 10 of the gap in wealth accumulation by comparison gender differences in earnings can account for 51 of the wealth gap the results have implications for recent economic and policy changes that are making individuals increasingly responsible for their own financial security financial security depends greatly on the ability to accumulate adequate retirement wealth wolff 1998 the results suggest that while the difference in risk tolerance does contribute to the gender gap in wealth accumulation the role of the gender gap in earnings remains a primary concern ii literature review gender differences in risk tolerance have been observed in responses to survey questions and risk tolerance instruments the national longitudinal survey of youth 1979 nlsy79 and the hrs both include a series of questions about choosing between two jobs one that pays respondents their current income with certainty and the other that has a 50 50 chance of doubling their income or reducing it by a certain fraction analyzing the hrs question barsky et al 1997 found that men tended to be somewhat more risk tolerant than women spivey 2008 corroborated this finding using the nlsy79 grable and lytton 1998 and sung and hanna 1996 studied the responses to a subjective risk tolerance question in the survey of consumer finances scf and concluded that women were significantly less risk tolerant than men grable 2000 used a used a 20 item instrument to assess risk tolerance among faculty and staff at a university and also found that women were less risk tolerant than men researchers have also made inferences about women s risk tolerance based on observed wealth accumulation and investment choices using scf data jianakoplos and bernasek 1998 found that as individuals wealth increased the proportion of wealth held in risky assets increased for both men and women but the effect was significantly smaller for single women they concluded that single women were less risk tolerant than single men dwyer et al 2002 found that women took less risk than men in their mutual fund investment decisions however the impact of gender on risk taking was reduced significantly when controlling for the investor s financial knowledge

democratic accountability and retrospective voting a laboratory experiment understanding the incentives of politicians requires understanding the nature of voting behavior i conduct a laboratory experiment to investigate whether voters focus on the problem of electoral selection or if they instead focus on electoral sanctioning if voters are forward looking but uncertain about politicians unobservable characteristics then it is rational to focus on selection but doing so undermines democratic accountability because selection renders sanctioning an empty threat in contrast to rational choice predictions the experimental results indicate a strong behavioral tendency to use a retrospective voting rule additional experiments support the interpretation that retrospective voting is a simple heuristic that voters use to cope with a cognitively difficult inference and decision problem and in addition suggest that voters have a preference for accountability the results pose a challenge for theories of electoral selection and voter learning and suggest new interpretations of empirical studies of economic and retrospective voting
