what drives deregulation economics and politics of the relaxation of bank branching restrictions this paper investigates private interest public interest and political institutional theories of regulatory change to analyze state level deregulation of bank branching restrictions using a hazard model we find that interest group factors related to the relative strength of potential winners large banks and small bank dependent firms and losers small banks and the rival insurance firms can explain the timing of branching deregulation across states during the last quarter century the same factors also explain congressional voting on interstate branching deregulation while we find some support for each theory the private interest approach provides the most compelling overall explanation of our results

capital income taxation with housing abstract this paper quantitatively investigates capital income taxation in the general equilibrium overlapping generations model with household heterogeneity and housing housing tax policy is found to affect how capital income should be taxed due to substitution between housing and non housing capital given the existing u s preferential tax treatment for owner occupied housing the optimal capital income tax rate is close to zero 1 contrary to the high optimal capital income tax rate found with overlapping generations models without housing 31 a low capital income tax rate improves welfare by narrowing a tax wedge between housing and non housing capital the narrowed tax wedge indirectly nullifies the subsidies taxes for homeowners renters and corrects over investment to housing naturally when the preferential tax treatment for owner occupied housing is eliminated a high capital income tax rate improves welfare as in the model without housing

banking deregulation and industry structure evidence from the french banking reforms of 1985 we investigate how the deregulation of the french banking industry in the 1980s affected the real behavior of firms and the structure and dynamics of product markets following deregulation banks are less willing to bail out poorly performing firms and firms in the more bank dependent sectors are more likely to undertake restructuring activities at the industry level we observe an increase in asset and job reallocation an improvement in allocative efficiency across firms and a decline in concentration overall these findings support the view that a more efficient banking sector helps foster a schumpeterian process of creative destruction many economies around the world are characterized by heavily regulated bank

earnings inequality among males in the united states trends and the effect of labor force growth we analyze the variance of log earnings within labor force cohorts of u s males with particular attention to the influence of labor force growth rates estimates with data from the 1968 79 current population surveys reveal increases in earnings inequality within labor force cohorts even after we control for the level of education experience and unemployment a model of human capital investment is used to analyze differences among cohorts in the life cycle profile of the variance of log earnings it is shown that a pattern of sharply increasing and then declining labor force growth rates will tend to raise the return on human capital investment and thereby increase the variance of postschooling investment and log earnings early in the life cycle this positive effect on relative earnings inequality should decline with experience and possibly become negative because of the post world war ii baby boom and baby bust recent labor force entrants have faced just such a pattern of actual and projected labor

capital taxation and accumulation in a life cycle growth model almost all of the serious economic work on savings decisions within the past decade has relied on some variant of the life cycle hypothesis in which savings arise out of individual choices of an optimum lifetime consumption path this paper reexamines the incidence and welfare consequences of capital income taxes within a realistic life cycle model the results suggest that the elimination of capital income taxation would have very substantial economic effects for example a complete shift to consumption taxation might raise steady state output by as much as 18 percent and consumption by 16 percent the long run welfare gain from such a shift would for plausible parameter values exceed 150 billion annually stated somewhat differently shifting to consumption taxation would raise the lifetime utility of the representative consumer by the equivalent of about six years income in the new steady state these estimates dwarf estimates of the static welfare cost of taxation and significantly exceed even extreme previous estimates of the dynamic loss this study departs from earlier analyses of the effects of taxes on capital income in several respects probably the most important difference between this treatment and most preceding ones lies in the assumptions about the interest elasticity of saving it is shown below that the common two period formulation of saving decisions yields quite misleading results a more realistic model of life cycle savings demonstrates that for a wide variety of plausible parameter values savings are very interest elastic this implies that shifting away from capital income taxation would significantly increase capital formation making possible long run increases in consumption many studies of the welfare effects of capital income taxation have ignored the general equilibrium effects of increased capital formation in an economy with life cycle savings there is no presumption that the undistorted growth path corresponds to any sort of social optimum as peter diamond has shown life cycle savings can lead to a steady state capital intensity either greater or less than the golden rule level more generally it is clear that there is no reason to believe that a life cycle economy will maximize any particular intertemporal social welfare function a fundamental tenet of welfare evaluation is that preexisting distortions must be considered in evaluating the consequences of tax changes the results presented in this paper take explicit account of the nonoptimal character of the no tax steady state this explains in large part why such a sizeable welfare effect of capital taxes is found in an economy far from the golden rule level of capital intensity there are substantial gains in steady state consumption achievable through increased capital formation section i of the paper examines the aggregate savings function in a continuous time life cycle framework the second section clarifies the differences between wage and consumption taxes an aggregate production function is added to complete the model in the third section the effects of changes in capital taxes on both steady state incidence and welfare are considered within a general equilibrium framework the final section of the paper discusses some implications of the results and suggests areas which appear to warrant further study assistant professor of economics massachusetts institute of technology and research analyst national bureau of economic research i am grateful to alan auerbach martin feldstein laurence kotlikoff to the participants in the nber workshop on business taxation and to the harvard public finance seminar for useful discussions james poterba and james buchal performed the numerical calculations

on the optimal progressivity of the income tax code this paper computes the optimal progressivity of the income tax code in a dynamic general equilibrium model with household heterogeneity in which uninsurable labor pro ductivity risk gives rise to a nontrivial income and wealth distribution a progressive tax system serves as a partial substitute for missing insurance markets and enhances an equal distribution of economic welfare these bene cial eects of a progressive tax system have to be traded oagainst the e ciency loss arising from distorting endoge nous labor supply and capital accumulation decisions a determination of the optimal progressivity of the income tax code therefore calls for a quantitative exploration using a utilitarian steady state social welfare criterion we nd that the optimal us income tax is well approximated by a at tax rate of19 5 and a xed deduction of about 3 700 the steady state welfare gains from a fundamental tax reform towards this tax system are equivalent to 0 4 higher consumption in each state of the world an explicit computation of the transition path induced by a reform of the current towards the optimal tax system indicates however that a majority of the population currently alive would suer welfare losses calling into question the political feasibility of such

the finance growth nexus evidence from bank branch deregulation this paper provides evidence that financial markets can directly affect economic growth by studying the relaxation of bank branch restrictions in the united states we find that the rates of real per capita growth in income and output increase significantly following intrastate branch reform we also argue that the observed changes in growth are the result of changes in the banking system improvements in the quality of bank lending not increased volume of bank lending appear to be responsible for faster growth

optimal capital income taxation with incomplete markets borrowing constraints and constant discounting for a wide class of infinitely lived agent models chamley has shown that the optimal capital income tax rate is zero in the long run lucas has argued that for the u s economy there is a significant welfare gain from switching to this policy this paper shows that for the bewley class of models with incomplete insurance markets and borrowing constraints the optimal tax rate on capital income is positive even in the long run therefore cutting the capital income tax to zero may well lead to welfare losses

household debt consumption and inequality abstract this paper examines the link between household credit shocks consumption and income inequality at the national level empirically we use country specific var models to estimate the dynamic responses of aggregate consumption to household credit shocks we then show in cross country regressions that the consumption response is more sensitive to such shocks in countries with higher levels of inequality even after controlling for financial development theoretically we construct and simulate a dynamic model based on the effect of inequality on the incidence of credit constraints to illustrate potential causal mechanisms

finance and business cycles the credit driven household demand channel what is the role of the financial sector in explaining business cycles this question is as old as the field of macroeconomics and an extensive body of research conducted since the global financial crisis of 2008 has offered new answers the specific idea put forward in this article is that expansions in credit supply operating primarily through household demand have been an important driver of business cycles we call this the credit driven household demand channel while this channel helps explain the recent global recession it also describes economic cycles in many countries over the past 40 years

house prices home equity based borrowing and the u s household leverage crisis us household leverage sharply increased in the years preceding the 2007 eco nomic recession the top panel of figure 1 shows the steady rise in household debt since 1975 which accelerated beginning in 2002 in just five years the household sector doubled its debt balance in comparison the contemporaneous increase in corporate debt was modest the middle panel shows that the increase in household debt from 2002 to 2007 translated into a striking rise in household leverage as mea sured by the debt to income ratio during the same time period corporate leverage declined the dramatic absolute and relative rise in us household leverage from 2002 to 2007 is unprecedented compared to the last 25 years one reason for the rapid expansion in household leverage during this period is that mortgage credit became more easily available to new home buyers mian and sufi 2009 strong house price appreciation from 2002 to 2006 however which may have been fueled by the availability of mortgage credit to a riskier set of new home buyers could also have had an important feedback effect on household lever age through existing homeowners given that 65 percent of us households already owned their primary residence before the acceleration in house prices the feedback from house prices to borrowing may be an important source of the rapid rise in household leverage that preceded the economic downturn our central goals in this study are to estimate how homeowner borrowing responded to the increase in house prices and to identify which homeowners responded most aggressively we examine this home equity based borrowing channel using a dataset consisting of anonymous individual credit files of a national consumer credit bureau agency we follow a random sample of over 74 000 us homeowners who owned their homes as of 1997 at an annual frequency from the end of 1997 until the end of 2008 the bottom panel of figure 1 plots the growth in debt of 1997 homeowners over time and shows that existing homeowners borrow significantly more debt as their house prices appreciate from 2002 to 2006 while the aggregate trend is suggestive

when credit bites back using data on 14 advanced countries between 1870 and 2008 we document two key facts of the modern business cycle relative to typical recessions financial crisis recessions are costlier and more credit intensive expansions tend to be followed by deeper recessions in financial crises or otherwise and slower recoveries we use local projection methods to condition on a broad set of macro economic controls to study how past credit accumulation impacts key macro economic variables such as output investment lending interest rates and inflation the facts that we uncover lend support to the idea that financial factors play an important role in the modern business cycle

the great mortgaging housing finance crises and business cycles this paper unveils a new resource for macroeconomic research a long run dataset covering disaggregated bank credit for 17 advanced economies since 1870 the new data show that the share of mortgages on banks balance sheets doubled in the course of the twentieth century driven by a sharp rise of mortgage lending to households household debt to asset ratios have risen substantially in many countries financial stability risks have been increasingly linked to real estate lending booms which are typically followed by deeper recessions and slower recoveries housing finance has come to play a central role in the modern macroeconomy

trends in intergenerational income mobility previous studies of recent u s trends in intergenerational income mobility have produced widely varying results partly because of large sampling errors by making more efficient use of the available information in the panel study of income dynamics we generate more reliable estimates of the recent time series variation in intergenerational mobility our results which pertain to the cohorts born between 1952 and 1975 do not reveal major changes in intergenerational mobility

how does credit supply expansion affect the real economy the productive capacity and household demand channels credit supply expansion can affect an economy by increasing productive capacity or by boosting household demand in this study we develop a test to determine if the household demand channel is present and we implement the test using both a natural experiment in the united states in the 1980s and an international panel of 56 countries over the last several decades consistent with the importance of the household demand channel we find that credit supply expansion boosts nontradable sector employment and the price of nontradable goods with limited effects on tradable sector employment such credit expansions amplify the business cycle and lead to more severe recessions

intergenerational earnings mobility and equality of opportunity in south africa summary the paper estimates the degree of intergenerational earnings persistence in south africa using microdata from the national income dynamics study nids the paper finds that intergenerational earnings mobility in south africa is low moreover a limited set of inherited circumstances explains a significant fraction of earnings inequality among male adults in particular race is shown to play a significant role the evidence provided for south africa is consistent with the hypothesis that low levels of intergenerational mobility and equality of opportunity are characteristic of high inequality emerging economies

optimal taxation in life cycle economies abstract we use a very standard life cycle growth model in which individuals have a labor leisure choice in each period of their lives to prove that an optimizing government will almost always find it optimal to tax or subsidize interest income the intuition for our result is straightforward in a life cycle model the individual s optimal consumption work plan is almost never constant and an optimizing government almost always taxes consumption goods and labor earnings at different rates over an individual s lifetime one way to achieve this goal is to use capital and labor income taxes that vary with age if tax rates cannot be conditioned on age a nonzero tax on capital income is also optimal as it can imperfectly mimic age conditioned consumption and labor income tax rates journal of economic literature classification numbers e62 h21

neglected risks financial innovation and financial fragility abstract we present a standard model of financial innovation in which intermediaries engineer securities with cash flows that investors seek but modify two assumptions first investors and possibly intermediaries neglect certain unlikely risks second investors demand securities with safe cash flows financial intermediaries cater to these preferences and beliefs by engineering securities perceived to be safe but exposed to neglected risks because the risks are neglected security issuance is excessive as investors eventually recognize these risks they fly back to the safety of traditional securities and markets become fragile even without leverage precisely because the volume of new claims is excessive

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

biases in standard measures of intergenerational income dependence abstract estimates of the most common mobility measure the intergenerational elasticity can be severely biased if snapshots are used to approximate lifetime income however little is known about biases in other popular dependence measures using long swedish income series we provide such evidence for log linear and rank correlations and rank based transition probabilities attenuation bias is considerably weaker in rank based measures life cycle bias is strongest in the elasticity moderate in log linear correlations and small in rank based measures however there are important exceptions persistence in the tails of the distribution is considerably higher and long distance downward mobility lower than estimates from short run income suggest

a quantitative analysis of capital income taxation this paper studies the quantitative impact of eliminating capital income taxation on capital accumulation and steady state welfare in a general equilibrium model with overlapping generations of sixty five period lived individuals who face idiosyncratic earnings risk borrowing constraints and life span uncertainty under a wide range of parameter configurations the capital income tax rate that maximizes steady state welfare is positive even though eliminating it completely would raise the steady state capital stock toward the golden rule this is because the tax burden is shifted toward the younger and liquidity constrained years reducing the individuals ability to self insure copyright 1998 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

on the distributional effects of reducing capital taxes this article asks whether household heterogeneity and market incompleteness have quantitatively important implications for the welfare effects of tax changes we compare a representative agent economy to an economy in which households face idiosyncratic uninsurable income risk the income process is consistent with empirical estimates and implies a realistic wealth distribution we find that capital tax cuts imply large welfare gains in the representative agent economy however when households are heterogeneous substantial redistribution during transition means that only a minority will support capital tax cuts whereas most households can expect large welfare losses

financial fragility in small open economies firm balance sheets and the sectoral structure episodes of large capital inflows in small open economies are often associated with a shift of resources from the tradable to the non tradable sector and sometimes lead to balance of payments crises this article builds a two sector dynamic model to study the evolution of the sectoral structure and its impact on financial fragility the model embeds a static mechanism of balance of payments crisis which produces multiple equilibria within a single time period when the non tradable sector is large enough compared to the tradable sector the article studies the dynamics induced by an increase in financial openness it shows that the relative size of the non tradable sector overshoots which makes the economy more likely to be financially fragile during the transitory dynamics using an extended version of the model the article conducts a quantitative analysis and shows that this mechanism accounts well for several episodes of large capital inflows that led to financial crises

ricardian equivalence revisited deficits gifts and bequests barro 1974 shows that operative altruistic transfer motives are key for ricardian equivalence to hold this paper evaluates the importance of this mechanism quantitatively by studying deficit financed tax cut experiments i use a heterogeneous agents overlapping generations economy with endogenously operative transfer motives to capture the fact that empirically transfers occur in some but not in all families altruism is calibrated to match aggregate transfer statistics i find that the response of aggregate consumption to a tax cut is in the ballpark of a standard overlapping generations economy that is an economy without altruistic family links welfare implications of this economy however move closer to a dynastic economy

redistributive taxation in a simple perfect foresight model abstract we investigate the redistributive potential of capital taxation in an intertemporal maximizing model of capital formation first even unanticipated redistributive capital taxation is severely limited in its effectiveness since it depresses wages second under any convergent redistributive tax policy which maximizes a paretian social objective the capital income tax will converge to zero independent of the factor supply elasticities these results are independent of workers holdings of capital

should we refinance unfunded social security within a continuous time overlapping generations model featuring endogenous intensive margin of the labour supply and retirement decision we analyse the issue of passing the burden of payroll revenues onto consumption or capital we find that large long run welfare gains occur when pension benefits are refinanced by consumption taxes however the transition to the new steady state is very painful for a large fraction of existing cohorts on the other hand the capital base is too small to sustain pension benefits but could be made larger if capital taxes are raised yet that would entail significant welfare losses

regression toward mediocrity in economic stature this paper provides estimates of the correlation in lifetime earnings between fathers and sons intergenerational data from the national longitudinal survey are used earlier studies conducted for the united states report elasticities of children s earnings with respect to parent s earnings of 0 2 or less suggesting extensive integenerational mobility these estimates however are biased downward by error contaminated measures of lifetime economic status estimates presented in this paper correct for the problem of measurement error and find the intergenerational correlation in income to be on the order of 0 4 this suggests considerably less intergenerational mobility than previously believed jel j62

intergenerational income mobility in the united states social scientists and policy analysts have long expressed concern about the extent of intergenerational income mobility in the united states but remarkably little empirical evidence is available the few existing estimates of the intergenerational correlation in income have been biased downward by measurement error unrepresentative samples or both new estimates based on intergenerational data from the panel study of income dynamics imply that the intergenerational correlation in long run income is at least 0 4 indicating dramatically less mobility than suggested by earlier research copyright 1992 by american economic association

random earnings differences lifetime liquidity constraints and altruistic intergenerational transfers abstract this paper develops a model of private savings behavior in which households care about their descendants cannot have negative net worth and have lifetime earnings depending on random draws from an exogenous distribution of abilities the elements interact very lucky parents are likely to leave large estates constrained children are unusually likely to receive intergenerational transfers the paper proves the existence of a stationary cross sectional distribution of wealth endogenously determines where liquidity constraints will bind and shows that the long term interest rate must be such that ricardian neutrality fails its last section generates several illustrative numerical simulations

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

the aggregate implications of regional business cycles during the last recession and its aftermath aggregate price growth and aggregate nominal wage growth remained robust despite the high rate of unemployment we document that u s states with weaker labor markets experienced lower price growth lower nominal wage growth and lower real wage growth during the great recession given that reliable measures of local prices do not exist we create our own state price indices using scanner data from the nielsen retail scanner database the main innovation of the paper is the development of an econometric procedure that combines cross region data with aggregate time series data to infer the underlying shocks driving both aggregate and regional business cycles applying our procedure to the great recession we find that a combination of both demand and supply shocks are necessary to account for the joint dynamics of aggregate prices wages and employment during the 2007 2012 period in contrast we find that only demand shocks are needed to explain the cross region variation the results suggest that only using cross region variation to explain aggregate fluctuations is insufficient when shocks do not have a substantive regional component

a welfare analysis of social security in a dynastic framework in this article we study the welfare effects of unfunded social security in a general equilibrium model populated with overlapping generations of altruistic individuals that differ in lifetime expectancy and earnings ability contrary to previous research our results indicate that steady state welfare increases with social security for most households although by very different amounts this result is mainly due to two factors first the presence of two sided altruism significantly mitigates the crowding out effect of unfunded social security second ability shocks and uncertain lifetimes generate significant heterogeneity among households to yield different induced preferences for social security

credit supply and the price of housing we show that since 1994 branching deregulations in the u s have signi cantly af fected the supply of mortgage credit and ultimately house prices with deregulation the number and volume of originated mortgage loans increase while denial rates fall but the deregulation has no eect on a placebo sample formed of mortgage compa nies that should not be aected by the regulatory change this sharpens the causal interpretation of our results deregulation acts to relax access to mortgage credit and pushes the demand for house ownership outwards interestingly the fraction of securi tized mortgage loans remains unchanged through the process we nd evidence house prices rise with branching deregulation and particularly in metropolitan areas where construction is inelastic for topographic reasons we document these results in a large sample of counties across the u s we also focus on a reduced cross section formed by counties on each side of a state border where a regression discontinuity approach is possible our conclusions are strengthened jel classi cation numbers g21 g10 g12

debt deflation theory and evidence abstract in the early 1990s the most severe recessions occurred in those countries which had experienced the largest increases in private debt burdens was this an accident of history or did it reflect deeper forces affecting market economies the paper comprises three parts first it presents three stylised facts about debt and its impact on consumption growth in the 1930s and the 1990s second it discusses the reception of irving fisher s work on debt deflation by his contemporaries and argues that it is helpful to think of debt deflation as a real business cycle phenomenon third there is a theoretical discussion of the reaction of debt and consumption to shocks in the context of a model of precautionary saving central to the model is the role of distributional shocks which implies that aggregate demand may be a nonmonotonic function of the price of assets in terms of the consumption good multiple equilibria may exist leading to the possibility of financial instability the analysis of debt deflation requires the construction of real business cycle models without a representative consumer

the efficiency gains from dynamic tax reform this paper presents a new simulation methodology for determining the pure efficiency gains from tax reform along the general equilibrium rational expectations growth path of life cycle economies the principal findings concern the effects of switching from a proportional income tax with rates similar to those in the u s to either a proportional tax on consumption or a proportional tax on labor income a switch to consumption taxation generates a sustainable welfare gain of almost 2 percent of lifetime resources in contrast a transition to wage taxation generates a loss of greater than percent of lifetime re sources a second general result is that even a mild degree of progressivity in the income tax system imposes a very large efficiency cost this abstract was borrowed from another version of this item

determining the motives for a positive optimal tax on capital previous literature demonstrates that in a computational life cycle model the optimal tax on capital is positive and large given the computational complexities of these overlapping generations models it is helpful to to determine the relative importance of the economic factors driving this result i highlight the impact of changing two common assumptions in a benchmark model that generates a large optimal tax on capital similar to the model in conesa et al 2009 first the utility function is altered such that it implies an agent s frisch labor supply elasticity is constant as opposed to increasing over his lifetime second the government is allowed to tax accidental bequests at a separate rate from ordinary capital income the main nding of this paper is that these two changes cause the optimal tax on capital to drop by almost half furthermore i nd that the welfare costs of adopting the high optimal tax on capital from the benchmark model in the model with the altered assumptions which calls for a lower tax on capital are equivalent to 0 35 percent of total lifetime consumption quantifying the impact of these assumptions in the benchmark model is important because the rst has limited empirical evidence and the second although included for tractability confounds a motive for taxing capital with a motive for taxing accidental bequests jel e62 h21

de jure interstate banking why only now this paper tackles three tasks it reviews the history of restrictions on interstate banking it summarizes the provisions of the interstate banking and branching efficiency act of 1994 underscoring the opt in and opt out lobbying pressure this act assigns to state legislatures finally the paper develops a lobbying pressure model designed to explain statutory changes in the framework of financial regulation the model implies that de facto liberalization of a regulatory regime precedes its de jure liberalization once adopted statutory restrictions on banks remain in place until technology and competitive regulatory enforcement have fashioned loopholes wide enough to reverse the statute sponsoring balance of lobbying pressure copyright 1996 by ohio state university press

credit induced boom and bust this paper exploits the federal preemption of national banks in 2004 from local laws against predatory lending to gauge the effect of the supply of credit on the real economy first the preemption regulation resulted in an 11 increase in annual lending in the 2004 2006 period which is associated with a 3 3 rise in annual house price growth rate and a 2 2 expansion of employment in nontradable sectors this was followed by a sharp decline in subsequent years furthermore we show that the increase in the supply of credit reduced delinquencies during boom years but increased them in bust years received june 7 2015 editorial decision december 22 2016 by editor robin greenwood

intergenerational persistence of earnings the role of early and college education recent empirical evidence from the united states indicates a high degree of persistence in earnings across generations designing effective public policies to increase social mobility requires identifying and measuring the major sources of persistence and inequality in earnings we provide a quantitative model of intergenerational human capital transmission that focuses on three sources innate ability early education and college education we find that approximately one half of the intergenerational correlation in earnings is accounted for by parental investment in education in particular early education we show that these results have important implications for education policy

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

optimal metering in the bottleneck congestion model abstract this paper examines whether metering entry to highways can reduce commuting costs we consider a modified version of the bottleneck congestion model which includes travel time downstream of the bottleneck the highway authority s choice of an entry rate enables it to substitute queuing time for travel time the authority s choice is constrained by the road s speed flow curve we find that the benefits of metering increase as the speed that would prevail in the absence of metering decreases and as the speed flow curve gets flatter the major cost of metering is providing a holding area for vehicles waiting to enter

family economics and macro behavior in this 1987 presidential address to the american economic association the author explores the contributions of the field of family economics to macroeconomic analysis the focus is on family behavior as an active endogenous factor that both affects and is affected by the evolution of the economy much of the time is spent on long term economic growth although i also discuss short and long cycles in economic activity and the interaction between overlapping generations through social security transmission of inequality and in other ways many conclusions in these and presumably other macro areas change radically when family choices get the attention they deserve excerpt

dynamic optimal taxation with private information we study dynamic optimal taxation in a class of economies with private information optimal allocations in these environments are complicated and history dependent yet we show that they can be implemented as competitive equilibria in market economies supplemented with simple tax systems the market structure in these economies is similar to that in bewley 1986 agents supply labour and trade risk free claims to future consumption subject to a budget constraint and a debt limit optimal taxes are conditioned only on two observable characteristics an agent s accumulated stock of claims or wealth and her current labour income we show that optimal taxes are generally non linear and non separable in these variables and relate the structure of marginal wealth and income taxation to the properties of agent preferences this paper studies optimal taxation in a class of dynamic economies with private information we consider an environment in which agents preferences are defined over consumption and labour and each agent receives a privately observed sequence of i i d preference shocks incentivecompatibility constraints stemming from private information imply that socially optimal or constrained efficient allocations in this environment are complicated and history dependent yet we show that they can be implemented as competitive equilibria in market economies supplemented with simple tax systems the market structure in these economies is identical to that in bewley 1986 huggett 1993 or aiyagari 1994 agents can trade current consumption for claims to future consumption subject to a budget constraint and a borrowing limit these claims have a non contingent pre tax return crucially taxes are conditioned upon only two observable characteristics of an agent current wealth given by the agent s accumulated stock of claims and current labour income they do not depend on any other aspect of an agent s past history most models of dynamic optimal taxation follow the ramsey approach in which the set of fiscal instruments available to the government is exogenously specified 1 linear labour and capital income taxes are typically included in this set while lump sum taxes are ruled out the exclusion of the latter is justified by appealing to incentive or administrative constraints but these are not explicitly modelled these exogenous restrictions on fiscal instruments represent frictions that the government seeks to ameliorate through its optimal choice of tax rates the approach we adopt in this paper builds on the optimal taxation literature initiated by mirrlees 1971 mirrlees assumes that agents receive privately observed shocks to their

optimal indirect and capital taxation we consider an environment in which agents skills are private information and follow arbitrary stochastic processes we prove that it is typically pareto optimal for an individual s marginal benefit of investing in capital to exceed his marginal cost of doing so this wedge is consistent with a positive tax on capital income we also prove that it is pareto optimal for the marginal rate of substitution between any two consumption goods to equal the marginal rate of transformation this lack of a wedge is consistent with uniform taxation of consumption goods within a period

a longitudinal analysis of sibling correlations in economic status numerous previous studies have used sibling correlations to measure the importance of family background as a determinant of economic status the sibling correlations estimated in these studies however have been depressed by a failure to distinguish transitory and permanent income variation and in some cases by overly homogeneous samples this paper presents a methodology to address these problems and applies it to longitudinal data from the panel study of income dynamics our main conclusion is that family background exerts greater influence on economic status than has been indicated by most earlier research

progressive taxation in a dynastic model of human capital abstract we develop a quantitative theory of economic inequality to investigate the effects of replacing the current u s progressive income tax system with a proportional one the cross sectional implications of the theory are used to discipline the assessment of the effects of tax policy and circumvent the lack of conclusive micro evidence on the parameterization of the human capital production technology we find that the elimination of progressive taxation increases steady state level of output by 12 6 capital by 21 8 and consumption by 13 2 moreover it increases economic inequality and its persistence across generations

banking integration and house price co movement abstract the correlation in house price growth across us states increased steadily between 1976 and 2000 this paper shows that the contemporaneous geographic integration of the us banking market via the emergence of large banks was a primary driver of this phenomenon to this end we first theoretically derive an appropriate measure of banking integration across state pairs and show that house price growth correlation is strongly related to this measure of financial integration our instrumental variable estimates suggest that banking integration can explain up to one fourth of the rise in house price correlation over this period

the panel study of income dynamics after fourteen years an evaluation this article considers the representativeness of the panel study of income dynamics psid over its 14 year history from 1968 to 1981 given the dynamics of entry and exit from the panel by 1981 40 of the original members had left the sample and were replaced by new entrants who joined either existing households or new households being formed by members of the original sample we consider the distribution of demographic characteristics and earnings equations over time and we compare the psid with the current population survey cps by either approach we find little evidence that the psid has become unrepresentative

altruism incomplete markets and tax reform abstract we compute the welfare effects of different revenue neutral tax reforms that eliminate capital income taxation in two general equilibrium models calibrated to the u s economy in our dynastic model the reform with the largest welfare gain is the one that eliminates all income taxation and increases the consumption tax to 35 75 of the population alive at the time of the reform benefit from it individuals use intervivos transfers and bequests to redistribute the long run benefits in a pure life cycle economy that lacks this redistribution technology we find that the same reform would benefit only 9 of the population

updated notes on the interindustry wage structure 1890 1990 the author documents and analyzes changes in wage structure across manufacturing industries over the years 1890 1990 interindustry differentials in wages were highly stable over that period for production workers but much less stable for nonproduction workers interindustry wage patterns were very similar for production and nonproduction workers in 1990 though this similarity dates back only to 1958 although dispersion of wages across industries followed varying trends over the period it was higher in 1990 than at any previous time in this century the variables that have been most strongly correlated with wage growth are productivity growth rising union density rising capital intensity and profit growth

optimal taxation of capital income in general equilibrium with infinite lives this paper analyzes the optimal tax on capital income in general equilibrium models of the second best agents have infinite lives and utility functions which are extensions from the koopmans form the population is heterogeneous the important property of the models is the equality between the social and the private discount rates in the long run i find that the optimal tax rate is zero in the long run for a special case of additively separable utility functions i then determine the tax rates along the dynamic path and conditions that are sufficient for the local stability of the steady state

the intergenerational effects of worker displacement this article uses variation induced by firm closures to explore the intergenerational effects of worker displacement using a canadian panel of administrative data that follows more than 39 000 father son pairs from 1978 to 1999 we find that children whose fathers were displaced have annual earnings about 9 lower than similar children whose fathers did not experience an employment shock they are also more likely to receive unemployment insurance and social assistance the estimates are driven by the experiences of children whose family income was at the bottom of the income distribution

wealth inequality in the united states since 1913 evidence from capitalized income tax data this paper combines income tax returns with flow of funds data to estimate the distribution of household wealth in the united states since 1913 we estimate wealth by capitalizing the incomes reported by individual taxpayers accounting for assets that do not generate taxable income we successfully test our capitalization method in three micro datasets where we can observe both income and wealth the survey of consumer finance linked estate and income tax returns and foundations tax records wealth concentration has followed a u shaped evolution over the last 100 years it was high in the beginning of the twentieth century fell from 1929 to 1978 and has continuously increased since then the rise of wealth inequality is almost entirely due to the rise of the top 0 1 wealth share from 7 in 1979 to 22 in 2012 a level almost as high as in 1929 the bottom 90 wealth share rst increased up to the mid 1980s and then steadily declined the increase in wealth concentration is due to the surge of top incomes combined with an increase in saving rate inequality top wealth holders are younger today than in the 1960s and earn a higher fraction of total labor income in the economy we explain how our ndings can be reconciled with survey of consumer finances and estate tax data

competitive risk sharing contracts with one sided commitment this paper analyzes dynamic equilibrium risk sharing contracts between profit maximizing intermediaries and a large pool of ex ante identical agents that face idiosyncratic income uncertainty that makes them heterogeneous ex post in any given period after having observed her income the agent can walk away from the contract while the intermediary cannot i e there is one sided commitment we consider the extreme scenario that the agents face no costs to walking away and can sign up with any competing intermediary without any reputational losses we demonstrate that not only autarky but also partial and full insurance can obtain depending on the relative patience of agents and financial intermediaries insurance can be provided because in an equilibrium contract an up front payment effectively locks in the agent with an intermediary we then show that our contract economy is equivalent to a consumption savings economy with one period arrow securities and a short sale constraint similar to bulow and rogoff 1989 from this equivalence and our characterization of dynamic contracts it immediately follows that without cost of switching financial intermediaries debt contracts are not sustainable even though a risk allocation superior to autarky can be achieved

the intergenerational conflict over the provision of public education abstract we study the intergenerational conflict over the provision of public education this conflict arises because older households without children have weaker incentives to support the provision of high quality educational services in a community than younger households with school age children we develop an overlapping generations model for households in a system of multiple jurisdictions this model captures the differences in preferred policies over the life cycle we show that the observed inequality in educational policies across communities is not only the outcome of stratification by income but is also determined by the stratification by age and a political process that is dominated by older voters in many urban communities with low quality of educational services the mobility of older households creates a positive fiscal externality since it creates a larger tax base per student this positive tax externality can dominate the negative effects that arise because older households tend to vote for lower educational expenditures as a consequence sorting by age can reduce the inequality in educational outcomes that is driven by income sorting

intergenerational transfers and the accumulation of wealth h t ouseholds acquire wealth from two sources they save out of income they have earned and they receive transfers from other people the first method of wealth accumulation goes under the name of life cycle saving in which people save during their working lives and dissave after retirement the second involves either an inter vivos transfer that is a transfer between living people or a bequest a transfer that occurs at the death of the donor while inter vivos transfers and bequests will arise in dynastic models where preferences include a taste for the well being of one s descendents few empirical life cycle models reflect these concerns indeed a sharp debate has arisen over the ability of the simple life cycle model to explain observed wealth accumulation understanding the relative sizes of these sources of wealth accumulation affects a variety of issues for example the effects of government debt social insurance public transfer programs estate taxes and incentives for charitable giving depend to some extent on the magnitude and nature of private saving and transfers of wealth analyses of the inequality of wealth may depend on whether most of wealth is earned or received as transfers appropriate policies for encouraging private saving may look rather different depending on whether most saving is to be consumed later in life or passed along to the next generation finally evidence on transfer patterns relates to more fundamental

intergenerational health mobility an empirical approach based on the echp despite the importance of the study of health mobility few attempts have been made to measure intergenerational mobility not only in the european union but also in other countries such as united states this article is focused on the study of intergenerational health mobility using data from the european community household panel echp in particular the relationships between self assessed health of parents and their sons are analysed the evidence obtained suggests that in spain sons reported health depends significantly on the self assessed health of their fathers

simulating fundamental tax reform in the united states this paper uses a new large scale dynamic life cycle simulation model to compare the welfare and macroeconomic effects of transitions to five fundamental alternatives to the u s federal income tax including a proportional consumption tax and a flat tax the model incorporates intragenerational heterogeneity and a detailed specification of alternative tax systems simulation results project significant long run increases in output for some reforms for other reforms namely those that seek to insulate the poor and initial older generations from adverse welfare changes long run output gains are modest
