learning your earning are labor income shocks really very persistent in this paper we examine the risk situation facing individuals in the labor market the current consensus in the literature is that the labor income process has a large random walk component we argue two points first the estimates of persistence from income data appear to be upward biased due to the omission of heterogeneity in income pro les across the population that would be implied for example by a human capital model with heterogeneity when we allow for dierences in pro les the estimated persistence falls from 0 99 to about 0 8 moreover the main evidence against pro le heterogeneity in the existing literature that the autocorrelations of income changes are small and typically negative is also replicated by the pro le heterogeneity model we estimate casting doubt on the previous interpretation of this evidence second we embed this process in a life cycle model to examine how it alters individuals consumption saving decision we assume that as seems plausible individuals do not know their pro les exactly at the beginning of life but learn in a bayesian way with successive income observations we nd that learning is very slow and aects consumption decision throughout the life cycle the model generates substantial rise in consumption inequality over the life cycle which matches empirical observations deaton and paxson 1994 moreover the shape of the age inequality pro le is non concave as in the data but unlike in a model with very persistent shocks finally the consumption pro les of college graduates are steeper than those of high school graduates in the model consistent with the data because they face a wider dispersion of and hence uncertainty about income growth rates overall this evidence indicates that income shocks may be signi cantly less persistent than what is currently assumed

governing india s land under conditions of market orientation and globalization land is being transferred from agriculture and common property uses to corporate farming private industry and the service sector how are intra and international land transactions governed using the case of india this paper emphasizes the sub national scale fieldwork in gujarat west bengal and tamil nadu reveals states to be competing with each other to attract private investment yet given institutional and political variation their land provision ranges from attempted market friendly policy change to narrower state business alliances it is time for scholarship and resultant policy recommendations to look beyond the national and global scales

income inequality in france 1901 1998 this paper uses data from income tax returns 1915 98 wage tax returns 1919 98 and inheritance tax returns 1902 94 in order to compute homogeneous yearly estimates of income wage and wealth inequality for twentieth century france the main conclusion is that the decline in income inequality that took place during the first half of the century was mostly accidental in france and possibly in a number of other countries as well wage inequality has been extremely stable in the long run and the secular decline in income inequality is for the most part a capital income phenomenon holders of large fortunes were badly hurt by major shocks during the 1914 45 period and they were never able to fully recover from these shocks probably because of the dynamic effects of progressive taxation on capital accumulation and pretax income inequality

does competition for capital discipline governments decentralization globalization and public policy competition among countries or regions within them to attract mobile capital is often thought to discipline their governments motivating them to invest more in infrastructure reduce waste and corruption and spend less on non productive public goods the result should be convergence on business friendly policies we argue that this requires an assumption units start out very similar that is often unrealistic if units are heterogeneous in natural resources geographical location inherited human capital or infrastructure capital mobility often weakens discipline on the poorlyendowed units this may help explain disappointing results of liberalizing capital flows within russia and sub saharan africa jel f36 h73 h87

energy and value abstract energy theories of value are reviewed and a new variant introduced based on the empirical relationship between price per unit mass and energy requirement per unit mass for a wide range of commodities the demand pattern of households in the uk and the usa for energy would tend to produce a declining ratio of energy to gross domestic product gdp however the tendency of goods with low energy intensity to be associated with low productivity gains introduces a counteracting effect and energy gdp ratios are fairly stable over time a simple relationship connecting energy intensity fuel price and time constant of adjustment is used to forecast retrospectively the energy use per dollar of gdp in each of seven countries for the year 1976

energy aesthetics and knowledge in complex economic systems it is argued that the fact that economic systems are dissipative structures must be taken fully into account in economics if we are to understand the nature of the economic ecological interface and how to deal with emergent environmental problems such as global warming such problems are a product of economic growth which is widely accepted to be the outcome of the acquisition and application of knowledge drawing upon disparate literatures within and outside economics it is argued that economic growth should be more properly viewed as the outcome of a co evolutionary process that involves the autocatalytic interaction of new knowledge and access of increasing amounts of free energy to do increasingly specialized forms of work specifically the relevance of the energy hypothesis associated with erwin schrodinger and more recently revived by eric schneider and his collaborators is assessed this hypothesis states that all dissipative structures have as their primary objective the reduction of accessible free energy gradients it is concluded that such a hypothesis cannot be rejected in the context of economic behaviour and that this opens up an important research agenda for economists

comparing inequality and mobility in linear models comment abstract this comment shows that peng 2018 s theorem 2 requires amendment a new set of relatively stricter assumptions is provided under which peng 2018 s findings in particular the asymmetric impact of capital and income risk on wealth mobility hold true and the approach developed therein proves suited for comparing stationary distributions of linear stochastic models

federalism chinese style the political basis for economic success in china china s remarkable economic success rests on a foundation of political reform providing a considerable degree of credible commitment to markets this reform reflects a special type of institutionalized decentralization that the authors call federalism chinese style this form of decentralization has three consequences first it fosters competition not only in product markets but also among local governments for labor and foreign capital this competition in turn encourages local government experimentation and learning with new forms of enterprises regulation and economic relationships second it provides incentives for local governments to promote local economic prosperity finally it provides a significant amount of protection to local governments and their enterprises from political intrusion by the central government

comparing inequality and mobility in linear models abstract this note shows that income risk and capital risk affect mobility and inequality asymmetrically in the linear model analysed by zhu 2013 inequality responds to changes in both income risk and capital risk while mobility responds to changes in capital risk and may not respond to changes in income risk consequently income tax reduces wealth inequality without affecting wealth mobility while tax on capital returns reduces wealth inequality and increases wealth mobility

wealth distribution with random discount factors abstract to explain the pareto tail behavior empirically observed in wealth distributions the quantitative macro literature has occasionally assumed that agents have random discount factors this paper formally proves that the stationary wealth distribution in a simple huggett model with random discounting has power law tails and characterizes the pareto exponents analytically i find that in general there is no clear relationship between the return on wealth and inequality and that the pareto exponent is highly sensitive to the persistence of the discount factor process i also provide a practical guidance for how to characterize the pareto exponents in richer models

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

the effects of partisan alignment on the allocation of intergovernmental transfers differences in differences estimates for spain abstract in this paper we test the hypothesis that municipalities aligned with upper tier grantor governments i e controlled by the same party will receive more grants than those that are unaligned we use a rich spanish database which provides information on grants received by nearly 900 municipalities during the period 1993 2003 from three different upper tier governments i e central regional and upper local since three elections were held at each tier during this period we have enough within municipality variation in partisan alignment to provide differences in differences estimates of the effects of alignment on the amount of grants coming from each source moreover the fact that a municipality may simultaneously receive grants from aligned and unaligned grantors allows us to use a triple differences estimator which consists of estimating the effects of changing alignment status on the change in grants coming from the aligned grantors relative to the change in grants coming from the unaligned ones the results suggest that partisan alignment has a sizeable positive effect on the amount of grants received by municipalities for example with majority governments at the two layers aligned municipalities receive over 40 more grants than unaligned ones

show me the money interjurisdiction political competition and fiscal extraction in china we argue that interjurisdiction competition in authoritarian regimes engenders a specific logic for taxation promotion seeking local officials are incentivized to signal loyalty and competence to their principals through tangible fiscal revenues the greater the number of officials accountable to the same principal the more intense political competition is resulting in higher taxation however too many officials accountable to the same principal leads to lower taxation due to shirking by uncompetitive officials and the fear of political instability using a panel dataset of all chinese county level jurisdictions from 1999 2006 we find strong evidence for an inverse u shaped relationship between the number of county level jurisdictions within a prefecture our proxy for the intensity of political competition and fiscal revenues in most provinces but not so in politically unstable ethnic minority regions the results are robust to various alternative specifications including models that account for heterogeneous county characteristics and spatial interdependence

the rise and decline of general laws of capitalism economists have long been drawn to the ambitious quest of discovering the general laws of capitalism david ricardo for example predicted that capital accumulation would terminate in economic stagnation and inequality as a greater and greater share of national income accrued to landowners karl marx followed him by forecasting the inevitable immiseration of the proletariat thomas piketty s 2014 tome capital in the twenty first century emulates marx in his title his style of exposition and his critique of the capitalist system piketty is after general laws that will demystify our modern economy and elucidate the inherent problems of the system and point to solutions but the quest for general laws of capitalism is misguided because it ignores the key forces shaping how an economy functions the endogenous evolution of technology and of the institutions and the political equilibrium that influence not only technology but also how markets function and how the gains from various different economic arrangements are distributed despite his erudition ambition and creativity marx was led astray because of his disregard of these forces the same is true of piketty s sweeping account of inequality in capitalist economies in the next section we review marx s conceptualization of capitalism and some of his general laws we then turn to piketty s approach to capitalism and his general laws we will point to various problems in piketty s interpretation of the economic relationships underpinning inequality but the most important shortcoming is that

power laws in economics an introduction paul samuelson 1969 was once asked by a physicist for a law in economics that was both nontrivial and true this is a difficult challenge as many roughly true results are in the end rather trivial for example demand curves slope down while many nontrivial results in economics in fact require too much sophistication and rationality on the part of the agents to actually hold true in practice 1 samuelson answered the law of comparative advantage the story does not say whether the physicist was satisfied the law of comparative advantage is a qualitative law and not a quantitative one as is the rule in physics indeed many of the insights of economics seem to be qualitative with many fewer reliable

going global in groups structural transformation and china s special economic zones overseas summary china s special economic zones helped the country industrialize by attracting foreign investment in 2006 beijing initiated an overseas trade and cooperation zone program assisting chinese companies to invest abroad while also building china s soft power through the transfer of a key component of china s development success little is known about the 19 zones approved so far under this program or the impact they are likely to have on structural transformation and industrial development in their host countries this paper identifies the 19 zones and their proposed locations the process of selection developers implementation and the chinese incentive regime it then focuses on the african zones using a typology of factors that have proven critical for zone development in the past the paper evaluates the potential of these zones for fostering structural transformation in africa

wealth inequality and intergenerational links previous work has had difficulty generating household saving behaviour that makes the distribution of wealth much more concentrated than that of labour earnings and that makes the richest households hold onto large amounts of wealth even during very old age i construct a quantitative general equilibrium overlapping generations model in which parents and children are linked by accidental and voluntary bequests and by earnings ability i show that voluntary bequests can explain the emergence of large estates while accidental bequests alone cannot and that adding earnings persistence within families increases wealth concentration even more i also show that the introduction of a bequest motive generates lifetime savings profiles more consistent with the data

the income and tax share of very high income households 1960 1995 this paper presents new information on the fraction of adjusted gross income and of wages and salaries that is reported by taxpayers in the top one half of one percent of the income distribution this corresponds to roughly five hundred thousand households in the late 1990s this paper relies on data from the treasury s individual income tax model for the period 1960 1995 the definition of adjusted gross income is standardized so that changes in the tax law do not affect the measured concentration of agi the results suggest that the share of agi reported by the highest income households increased significantly between the early 1980s and the mid 1990s with most of the increase taking place in the years immediately following the tax reform act of 1986 while we find some evidence of transitory changes in the concentration of income around major tax changes which may be the result of income retiming by high income taxpayers re timing does not seem to explain most of the changes since 1986 this abstract was borrowed from another version of this item

systemic risk in banking networks advantages of tiered banking systems abstract this paper studies the risk and potential impact of system wide defaults in a tiered banking network where a small group of head institutions has many credit linkages with other banks while the majority of banks have only a few links a network is random and displays a given distribution of the number of banks linkages known as degree we model tiering by a negative correlation between degrees of neighboring banks and by a scale free degree distribution the main findings of the paper highlight the advantages of tiering both the risk of systemic crisis and the potential scope of the crisis are lower in systems with negative correlation of bank degrees than in other types of systems similarly in scale free networks the resilience of the system to shocks is increasing with the level of tiering

recursive preferences learning and large deviations we estimate the relative contribution of recursive preferences versus adaptive learning in accounting for the tail thickness of price dividends rents ratios we find that both of these sources of volatility account for volatility in liquid stocks but not illiquid housing assets

do special economic zones induce developmental spillovers evidence from india s states abstract do special economic zones induce local development research drawing on the case of china s special economic zones suggests that subnational polities can target the location of export zones in order to catalyze local and regional socioeconomic development since 2006 a number of indian states have pushed forward similar zones in the face of accusations of land grabbing arguing that the zones will be engines for improvement in exports employment and infrastructure i argue that local development spillovers are an important albeit previously understudied dimension by which to evaluate the effects of special economic zones i then present the first systematic analysis of the developmental effects of india s sezs leveraging an original dataset on their locations together with 2001 and 2011 census data containing a host of social and economic developmental variables the findings show these sezs have failed to bring about local socioeconomic development to explain this absence of developmental spillovers i provide a theoretical framework based on the crucial role of political economy incentive structures facing local politicians i outline the mechanism through which indian state politicians use state owned development corporations for rent capture undermining the potential effectiveness of sezs and leading to their developmental failures the combination of available means for extracting rents and the limited political constraints on such rent extraction leads to a lack of developmental spillovers this framework can also help to explain the difference in the effects of sezs in india and in china these findings have theoretical importance for understanding the conditions under which subnational polities can use export zones and other export policies to catalyze development and practical implications for understanding the mixed pattern of sez success across the world

the role of labor income risk in household risk taking abstract in fifteen european countries china and the us stocks and business equity as a share of total household assets are represented by an increasing and convex function of income wealth a parsimonious model fitted to the data shows why background labor income risk can explain much of this risk taking pattern uncontrollable labor income risk stresses middle income households more because labor income is a larger fraction of their total lifetime resources compared with the rich in response middle income households reduce controllable financial risk richer households having less pressure can afford more risk taking the poor take low risk because they avoid jeopardizing their subsistence consumption

income inequality in the united states 1913 1998 this paper presents new homogeneous series on top shares of income and wages from 1913 to 1998 in the united states using individual tax returns data top income and wages shares display a u shaped pattern over the century our series suggest that the large shocks that capital owners experienced during the great depression and world war ii have had a permanent effect on top capital incomes we argue that steep progressive income and estate taxation may have prevented large fortunes from fully recovering from these shocks top wage shares were flat before world war ii dropped precipitously during the war and did not start to recover before the late 1960s but are now higher than before world war ii as a result the working rich have replaced the rentiers at the top of the income distribution

local economic development agglomeration economies and the big push 100 years of evidence from the tennessee valley authority we study the long run eects of one of the most ambitious place based economic development policies in u s history the tennessee valley authority using a rich panel dataset of counties we conduct an evaluation of the dynamic eects of the tva on local economies in the seventy years following the program s inception we nd that the tva led to short run gains in agricultural employment that were eventually reversed while impacts on manufacturing employment continued to intensify well after the program s subsidies had lapsed a pattern consistent with the presence of strong agglomeration economies in the manufacturing sector economists have long cautioned that the local gains created by place based policies may be oset by losses elsewhere yielding ambiguous eects on the u s as a whole building on the framework in glaeser and gottlieb 2008 we develop a novel approach to assessing the aggregate consequences of shifting the spatial distribution of manufacturing employment our ndings suggest the aggregate productivity gains associated with relocating manufacturing activity to the tva region were probably minimal

accounting for the u s earnings and wealth inequality we show that a theory of earnings and wealth inequality based on the optimal choices of ex ante identical households that face uninsured idiosyncratic shocks to their endowments of efficiency labor units accounts for the u s earnings and wealth inequality almost exactly

random walk to innovation why productivity follows a power law abstract this paper examines a search model in which knowledge is created as rational but poorly informed innovators obtain new ideas from combinations of existing ideas we assume that the productivity of an idea is stochastic and depends on the productivity of the parental ideas importantly we assume that the contribution of these parents to the productivity of the final idea is enhanced by prior use of these in knowledge creation we identify conditions on the search costs leading to two properties 1 the tail of the distribution of the productivity of innovations is a power law and 2 the number of citations i e times an idea is used in the process of innovation follows a displaced power law both these properties are consistent with the available empirical evidence on the productivity of innovations and on patent citations

a tale of fat tails abstract we document the extent to which major macroeconomic series used to inform linear dsge models can be characterized by power laws whose indices we estimate via maximum likelihood assuming data follow a linear recursion with multiplicative noise low estimated indices suggest fat tails we then ask whether standard dsge models under constant gain learning can replicate those fat tails by an appropriate increase in the estimated gain and without much change in the transmission mechanism of shocks we find that is largely the case via implementation of a minimum distance estimation method that eschews any allegiance to distributional assumptions

on the heterogeneous welfare gains and losses from trade how are the gains and losses from trade distributed across individuals within a country first we document that tradable goods constitute a larger fraction of expenditures for poor households second we build a trade model with nonhomothetic preferences to generate the documented relationship between tradable expenditure shares income and wealth and uninsurable earnings risk to generate heterogeneity in income and wealth third we use the calibrated model to quantify the differential welfare gains and losses from trade along the income and wealth distribution in a numerical exercise we permanently reduce trade costs so as to generate a rise in import share of gdp commensurate with that seen in the data from 2001 to 2014 we find that households in the lowest wealth decile experience welfare gains over the transition measured by permanent consumption equivalents that are 67 percent larger than those in the highest wealth decile

pareto and piketty the macroeconomics of top income and wealth inequality abstract since the early 2000s research by thomas piketty emmanuel saez and their coauthors has revolutionized our understanding of income and wealth inequality in this paper i highlight some of the key empirical facts from this research and comment on how they relate to macroeconomics and to economic theory more generally one of the key links between data and theory is the pareto distribution the paper describes simple mechanisms that give rise to pareto distributions for income and wealth and considers the economic forces that influence top inequality over time and across countries for example it is in this context that the role of the famous r g expression is best understood

nonparametric methods and local time based estimation for dynamic power law distributions summary this paper introduces nonparametric econometric methods that characterize general power law distributions under basic stability conditions these methods extend the literature on power laws in the social sciences in several directions first we show that any stationary distribution in a random growth setting is shaped entirely by two factors the idiosyncratic volatilities and reversion rates a measure of cross sectional mean reversion for different ranks in the distribution this result is valid regardless of how growth rates and volatilities vary across different economic agents and hence applies to gibrat s law and its extensions second we present techniques to estimate these two factors using panel data third we describe how our results imply predictability as higher ranked processes must on average grow more slowly than lower ranked processes we employ our empirical methods using data on commodity prices and show that our techniques accurately describe the empirical distribution of relative commodity prices we also show that rank based out of sample forecasts of future commodity prices outperform random walk forecasts at a 1 month horizon

inheritance and wealth inequality evidence from population registers we use new population wide register data on inheritances and wealth in sweden to estimate the causal impact of inheritances on wealth inequality we find that inheritances reduce relative wealth inequality e g the gini coefficient falls by 5 10 percent but that absolute dispersion increases examining different parts of the wealth distribution we find that the top decile s wealth share decreases substantially whereas the wealth share of the bottom half increases from a negative to a positive share in essence wealthier heirs inherit larger amounts but less wealthy heirs inherit more relative to their pre inheritance wealth we also find that post inheritance behavioral adjustments mitigate the equalizing effect of inheritances because less wealthy heirs consume larger shares of their inheritances moreover we find that the swedish inheritance tax reduced the equalizing inheritance effect but that the redistribution of tax revenues could reverse this result finally we show that inheritances increase wealth mobility

risk uncertainty and the dynamics of inequality abstract the dynamics of wealth inequality are studied in a continuous time blanchard yaari model investment returns are idiosyncratic and subject to knightian uncertainty in response agents formulate robust portfolio policies these policies are nonhomothetic wealthy agents invest a higher fraction of their wealth in uncertain assets yielding higher mean returns this produces a feedback mechanism that amplifies inequality it also produces an accelerated rate of convergence which helps resolve a puzzle recently identified by gabaix et al 2016 an empirically plausible increase in uncertainty can account for about half of the recent increase in top wealth shares

wealth distribution and social mobility in the us a quantitative approach we quantitatively identify the factors that drive wealth dynamics in the united states and are consistent with its skewed cross sectional distribution and with social mobility we concentrate on three critical factors i skewed earnings ii differential saving rates across wealth levels and iii stochastic idiosyncratic returns to wealth all of these are fundamental for matching both distribution and mobility the stochastic process for returns which best fits the cross sectional distribution of wealth and social mobility in the united states shares several statistical properties with those of the returns to wealth uncovered by fagereng et al 2017 from tax records in norway

income and wealth heterogeneity in the macroeconomy how do movements in the distribution of income and wealth affect the macroeconomy we analyze this question using a calibrated version of the stochastic growth model with partially uninsurable idiosyncratic risk and movements in aggregate productivity our main finding is that in the stationary stochastic equilibrium the behavior of the macroeconomic aggregates can be almost perfectly described using only the mean of the wealth distribution this result is robust to substantial changes in both parameter values and model specification our benchmark model whose only difference from the representative agent framework is the existence of uninsurable idiosyncratic risk displays far less cross sectional dispersion and skewness in wealth than u s data however an extension that relies on a small amount of heterogeneity in thrift does succeed in replicating the key features of the wealth data furthermore this extension features aggregate time series that depart significantly from permanent income behavior

earnings inequality and other determinants of wealth inequality abstract we study the relation between the distribution of labor earnings and the distribution of wealth we show theoretically as well as empirically that while labor earnings and precautionary savings are important determinants of wealth inequality factors they cannot by themselves account for the thick tail of the large top shares in the observed distribution of wealth other determinants like stochastic returns to wealth as well as savings rates and rates of returns increasing in wealth need to be accounted for

energy requirements of household consumption a case study of the netherlands this article describes the results of several research programmes that together aim at the development and application of methodologies that enable the study of long term environmental effects mainly related to the total household energy demand of household consumption in relation to other economic sectors this is usually described as the household metabolism approach in this article we use energy consumption and co2 emissions as proxies for long term impacts on the environment the major long term environmental effects of several hundred dutch household consumption categories have been determined by means of the hybrid energy analysis methodology total energy consumption and related co2 emission data have been calculated as a function of household income and family type past trends have been studied by a time series 1950 1990 analysis technical reduction potentials have been calculated for mid and long term scenarios it is concluded that the set of methodologies described form a useful tool for the analysis of unsustainable trends in household consumption patterns and associated energy requirements in the past and the present the results indicate that present trends lead towards unsustainability however reversal of these trends is feasible if this starts in the immediate future and if it is maintained for decades c 1999 elsevier science b v all rights reserved

the distribution of wealth and fiscal policy in economies with finitely lived agents we study the dynamics of the distribution of wealth in an overlapping generation economy with finitely lived agents and intergenerational transmission of wealth financial markets are incomplete exposing agents to both labor and capital income risk we show that the stationary wealth distribution is a pareto distribution in the right tail and that it is capital income risk rather than labor income that drives the properties of the right tail of the wealth distribution we also study analytically the dependence of the distribution of wealth of wealth inequality in particular on various fiscal policy instruments like capital income taxes and estate taxes and on different degrees of social mobility we show that capital income and estate taxes can significantly reduce wealth inequality as do institutions favoring social mobility finally we calibrate the economy to match the lorenz curve of the wealth distribution of the u s economy

did government decentralization cause china s economic miracle many scholars attribute china s market reforms and the remarkable economic performance they have fostered in part to the country s political and fiscal decentralization political decentralization is said to have stimulated local policy experiments and restrained predatory central interventions fiscal decentralization is thought to have motivated local officials to promote development and harden enterprises budget constraints the locally diversified structure of the prereform economy is said to have facilitated liberalization reexamining these arguments the authors find that none establishes a convincing link between political or fiscal decentralization and china s successes they suggest an alternative view of the reform process in which growth enhancing policies emerged from competition between promarket and conservative factions in beijing

the disadvantaged incumbents estimating incumbency effects in indian state legislatures this paper estimates the incumbency effects using a large dataset on state legislative elections in india during 1975 2003 i use a regression discontinuity design rdd that estimates the causal effect of incumbency by comparing candidates in closely fought elections i find that there is a significant disadvantage to incumbency in indian state legislative elections and the adverse effect of incumbency has increased after 1991 also the incumbency disadvantage is higher in states that have lower availability of public goods such as health centers and lower employment poverty and per capita income

a schumpeterian model of top income inequality top income inequality rose sharply in the united states over the last 40 years but increased only slightly in france and japan why we explore a model in which heterogeneous entrepreneurs broadly

the dynamics of inequality the past forty years have seen a rapid rise in top income inequality in the united states while there is a large number of existing theories of the pareto tail of the long run income distributions almost none of these address the fast rise in top inequality observed in the data we show that standard theories which build on a random growth mechanism generate transition dynamics that are too slow relative to those observed in the data we then suggest two parsimonious deviations from the canonical model that can explain such changes scale dependence that may arise from changes in skill prices and type dependence that is the presence of some high growth types these deviations are consistent with theories in which the increase in top income inequality is driven by the rise of superstar entrepreneurs or managers

the wealth distribution in bewley economies with capital income risk abstract we study the wealth distribution in bewley economies with idiosyncratic capital income risk we show analytically that under rather general conditions on the stochastic structure of the economy a unique ergodic distribution of wealth displays a fat tail

thomas piketty and the rate of time preference using a standard model in which the individual consumption path is computed solving an optimal control problem we investigate central claims of piketty 2014 rather than r g confirmed in the data r g with being the rate of time preference matters if this condition holds and the elasticity of substitution in the production function is larger than one the capital share converges to one in the long run nevertheless this does not have major impact on the distribution of wealth the latter however converges to maximum inequality for heterogeneous time preferences or rates of interest either persistent or stochastic for the latter the presence of finite life times leads to a distribution with finite wealth inequality featuring fat tails

investor sophistication and capital income inequality abstract capital income inequality is large and growing fast accounting for a significant portion of total income inequality we study its growth in a general equilibrium portfolio choice model with endogenous information acquisition and heterogeneity across household sophistication and asset riskiness the model implies capital income inequality that grows with aggregate information technology investors differentially adjust both the size and the composition of their portfolios as unsophisticated investors retrench from trading risky securities and shift their portfolios to safer assets technological progress also reduces aggregate returns and increases the volume of transactions features that are consistent with recent u s data

distribution of wealth and incomplete markets theory and empirical evidence abstract this paper analyses the equilibrium distribution of wealth in an economy where firms productivities are subject to idiosyncratic shocks returns on factors are determined in competitive markets households have linear consumption functions and government imposes taxes on capital and labour incomes and equally redistributes the collected resources to households the equilibrium distribution of wealth is explicitly calculated and its shape crucially depends on market incompleteness with incomplete markets it follows a paretian law in the top tail and the pareto exponent depends on the saving rate on the net return on capital on the growth rate of population and on portfolio diversification the characteristics of the labour market crucially affects the bottom tail but not the upper tail of the distribution of wealth in the case of completely decentralized labour market the analysis also suggests a positive relationship between growth and wealth inequality the theoretical predictions find a corroboration in the empirical evidence of united states in the period 1989 2004

traveling agents political change and bureaucratic turnover in india abstract we develop a framework to empirically examine how politicians with electoral pressures control bureaucrats with career concerns and the consequent implications for bureaucrats career investments unique microlevel data on indian bureaucrats support our key predictions politicians use frequent reassignments transfers across posts of varying importance to control bureaucrats high skilled bureaucrats face less frequent political transfers and lower variability in the importance of their posts we find evidence of two alternative paths to career success officers of higher initial ability are more likely to invest in skill but caste affinity to the politician s party base also helps secure important positions

resource accounting an application to development planning abstract economic projections because they are based on assupmtions about future values become increasingly unreliable as they move into the long term future in a search for a more robust way of assessing a country s long term development prospects in the light of feasible or seemingly desirable policies with respect to population resources agriculture and development a concept called resource accounting has been explored here one measures the physical effort required to carry through an economic activity rather than its cost the concept rests on the observation that if any economic activity is analyzed retrospectively in physical terms ultimately all output is found to rest on present and past labor and present and past energy use since labor in terms of quantity if not quality is generally in surplus in any economy enjoying technological progress one can quantity economic activities in terms of present and past energy use to establish the future feasible level of material welfare of an economy and its approach to sustainability in the context of its present status and known resources this concept has been put to work as a simulation model iniatially development for unesco s population division in order to assess the potential for enhancing the sustainable carrying capacity of nation states

social capital as obstacle to development brokering land norms and trust in rural india summary based on a study of how rural land brokers mediate the arrival of a special economic zone in rural rajasthan this paper argues that theories of collective social capital cannot explain how networks norms and trust interact in a process of economic change it then reconstructs bourdieu s distinct theory of individual social capital by showing how better connected farmers are able to broker land and capture profits at the expense of fellow villagers undermining trust norms and collective action it argues that social capital is most plausibly seen as an aspect of social inequality that hinders inclusive development

the risk free rate in heterogeneous agent incomplete insurance economies abstract why has the average real risk free interest rate been less than one percent the question is motivated by the failure of a class of calibrated representative agent economies to explain the average return to equity and risk free debt i construct an economy where agents experience uninsurable idiosyncratic endowment shocks and smooth consumption by holding a risk free asset i calibrate the economy and characterize equilibria computationally with a borrowing constraint of one year s income the resulting risk free rate is more than one percent below the rate in the comparable representative agent economy

instability and concentration in the distribution of wealth abstract we consider a setup in which infinitely lived households face idiosyncratic investment risk and show that in this case the equilibrium distribution of wealth becomes increasingly right skewed over time until wealth concentrates entirely at the top the households in our setup are identical in terms of their patience and their abilities and we assume that there are no redistributive mechanisms neither explicit in the form of government tax or fiscal policies nor implicit in the form of limited intergenerational transfers our results demonstrate that the presence of such redistributive mechanisms alone ensures the stability of the distribution of wealth over time

heterogeneity in returns to wealth and the measurement of wealth inequality lacking a long time series on the assets of the very wealthy saez and zucman 2015 use us tax records to obtain estimates of wealth holdings by capitalizing asset income from tax returns they document marked upward trends in wealth concentration we use data on tax returns and actual wealth holdings from tax records for the whole norwegian population to test the robustness of the methodology we document that measures of wealth based on the capitalization approach can lead to misleading conclusions about the level and the dynamics of wealth inequality if returns are heterogeneous and even moderately correlated with wealth

heterogeneous life cycle profiles income risk and consumption inequality was the increase in income inequality in the us due to permanent shocks or merely to an increase in the variance of transitory shocks the implications for consumption and welfare depend crucially on the answer to this question we use consumer expenditure survey cex repeated cross section data on consumption and income to decompose idiosyncratic changes in income into predictable life cycle changes transitory and permanent shocks and estimate the contribution of each to total inequality our model fits the joint evolution of consumption and income inequality well and delivers two main results first we find that permanent changes in income explain all of the increase in inequality in the 1980s and 1990s second we reconcile this finding with the fact that consumption inequality did not increase much over this period our results support the view that many permanent changes in income are predictable for consumers even if they look unpredictable to the econometrician consistent with models of heterogeneous income profiles

big banks idiosyncratic volatility and systemic risk starting in the 1990s us bank assets grew more concentrated among a few large institutions we explore the changing role of idiosyncratic volatility as a shaping force of the bank asset power law distribution our results reveal that idiosyncratic asset volatilities for bank holding companies declined since the 1990s to the extent that firm specific shocks can have significant macroeconomic consequences this result implies that even as one obvious source of aggregate risk and contagion bank asset concentration has increased another important source idiosyncratic volatility has diminished

the market for public office why the indian state is not better at development abstract how and why officials are transferred from one post to another can in india does have far reaching consequences for the effectiveness of public service organizations such as irrigation agriculture forestry and soil conservation departments the transfer mechanism used in many departments of indian states involves a kind of internal labor market a truer market than in the way that term is often used by labor market economists it allows pressures for corrupt behavior to bear down on the incumbents of certain posts and itself amplifies those pressures frequently the pressures on officials to be corrupt cause them to behave in ways contrary to the ostensible objectives of their departments why is the indian state not better at promoting development to an important degree because of the corruption transfer mechanism and its effects on bureaucratic initiatives
