individual taxpayer response to tax cuts 1982 1984 with implications for the revenue maximizing tax rate abstract this paper measures the response of taxpayers to the u s personal rate reductions from 1982 to 1984 a baseline income distribution is created to describe what level and distribution could be expected in the absence of tax changes comparison of this baseline with actual tax return data shows that at least one sixth and probably one quarter of the revenue ascribable to the rate reductions was recouped by changes in taxpayer behavior the data also show that federal income tax revenue would have been maximized at a tax rate of about 35 percent and total income tax revenue maximized at a total tax rate of about 40 percent

the tale of the tails canadian income inequality in the 1980s and 1990s we present new evidence on levels and trends in after tax income inequality in canada between 1980 and 2000 we argue that existing data sources may miss changes in the tails of the income distribution and that many of the changes in the income distribution have been in the tails for this reason we turn to an alternative source in particular we construct data on after tax and transfer income using census files augmented with predicted taxes based on information available from administrative tax data using these data we find that canadian after tax inequality levels are substantially higher than has been previously recognized primarily because income levels are lower at the bottom of the distribution than in commonly used survey data we also find larger long term increases in after tax income inequality and far more variability over the economic cycle this raises interesting questions about the role of the tax and transfer system in mitigating both trends and fluctuations in market income inequality les auteurs presentent de nouveaux resultats sur les niveaux et tendances de l inegalite des revenus apres impots au canada entre 1980 et 2000 on suggere que les donnees existantes peuvent avoir ignore des changements dans les extremites de cette distribution alors que le gros des changements y etait concentre pour cette raison les auteurs se sont tournes vers une autre source de donnees ils ont construit une base de donnees sur les revenus apres impots et les paiements de transfert en utilisant les donnees du recensement ainsi que des donnees additionnelles sur les impots prevus a partir de renseignements disponibles dans les dossiers administratifs on decouvre que les niveaux d inegalite des revenus apres impots sont beaucoup plus eleves que ce qu on a suggere jusqu ici d abord parce que les niveaux de revenus sont plus bas au pied de la distribution que ne le suggerent les donnees d enquetes on decouvre aussi un accroissement plus grand a long terme de l inegalite des revenus apres impots et une plus grande variabilite au cours du cycle economique voila qui souleve des questions interessantes a propos du role de la fiscalite et du systeme de paiements de transfert dans la modulation de la tendance et des fluctuations dans l inegalite des revenus du marche

the evolution of high incomes in northern america lessons from canadian evidence this paper uses tax statistics to construct new series on canadian top income shares from 1920 to 2000 and provides a systematic comparison with the u s experience as in the united states top income shares in canada display a ushaped pattern over the century with a precipitous drop during world war ii followed by a slower decline until 1970 since the late 1970s top income shares have been increasing dramatically and the very top shares are now as high as in the pre war era as in the united states the recent increase in top income shares is the consequence of a surge in top wages and salaries the canadian experience since the late 1970s does not appear to be well explained by tax changes suggesting that the upward trend in canada derives from the united states perhaps because many high income canadians have an emigration option this in turn suggests that the recent increase in u s personal income top shares is not merely a change in tax reporting behavior the recent sharp increase in top income shares in canada is of the same magnitude at the individual and family level and is not due to an increase in income mobility

an impossibility theorem for wealth in heterogeneous agent models with limited heterogeneity abstract it has been conjectured that canonical bewley huggett aiyagari heterogeneous agent models cannot explain the joint distribution of income and wealth the results stated below verify this conjecture and clarify its implications under very general conditions we show in particular that if i agents are infinitely lived ii saving is risk free and iii agents have constant discount factors then the wealth distribution inherits the tail behavior of income shocks e g light tailedness or the pareto exponent our restrictions on utility require only that relative risk aversion is bounded and a large variety of income processes are admitted our results show conclusively that it is necessary to go beyond standard models to explain the empirical fact that wealth is heavier tailed than income we demonstrate through examples that relaxing any of the above three conditions can generate pareto tails

are those paid more really more productive the case of experience this study uses computerized personnel microdata on the white male managerial and professional employees at a major u s corporation to address the following question can the additional earnings which are associated with more labor market experience at a point in time really be explained by higher productivity at the same point in time our answer to this question based on both cross sectional and longitudinal information is that performance plays a substantially smaller role in explaining cross sectional experience earnings differentials and earnings growth than is claimed by those who have adopted the human capital explanation of the experience earnings profile this response depends critically on our assumption that the performance ratings which supervisors give to their white male managerial and professional subordinates adequately reflect the subordinates relative productivity in the year of assessment we present a great deal of evidence which strongly supports this assumption

using elasticities to derive optimal income tax rates this paper derives optimal income tax formulas using compensated and uncompensated elasticities of earnings with respect to tax rates a simple formula for the high income optimal tax rate is obtained as a function of these elasticities and the thickness of the top tail of the income distribution in the general non linear income tax problem this method using elasticities shows precisely how the different economic effects come into play and which are the key relevant parameters in the optimal income tax formulas of mirrlees the optimal non linear tax rate formulas are expressed in terms of elasticities and the shape of the income distribution these formulas are implemented numerically using empirical earning distributions and a range of realistic elasticity parameters

the optimum quantity of debt abstract we find that the welfare gains to being at the optimum quantity of debt rather than the current us level are small and therefore concerns regarding the high level of debt in the us economy may be misplaced this finding is based on a model of a large number of infinitely lived households whose saving behavior is influenced by precautionary saving motives and borrowing constraints this model incorporates a different role for government debt than is found in standard models and it captures different cost benefit trade offs on the benefit side government debt enhances the liquidity of households by providing an additional means of smoothing consumption and by effectively loosening borrowing constraints on the cost side the implied taxes have adverse wealth distribution and incentive effects in addition government debt crowds out capital via higher interest rates and lowers per capita consumption

from theory to practice canadian economists contributions to public finance we survey canadian economists contributions to the field of public finance from the mid 1980s to 2016 we highlight the development and extension of the models and tools of public economics and the empirical studies that have deepened our understanding of the efficiency and distributional issues over a wide range of public finance issues we also highlight contributions to the development of policies through commissioned reports and the important role that canadian institutions the canadian tax foundation the think tanks and the federal and provincial departments of finance have played in shaping tax and fiscal policies de la theorie a la pratique contributions des economistes canadiens a la finance publique on examine les contributions des economistes canadiens au domaine de la finance publique du milieu des annees 1980 a 2016 on souligne le developpement et l extension des modeles et des outils d economie publique et les etudes empiriques qui ont aide a approfondir notre comprehension des enjeux d efficacite et de distribution dans un vaste eventail de questions de finance publique on souligne aussi les contributions des rapports commandites au developpement de politiques publiques ainsi que le role important d institutions canadiennes l association canadienne d etudes fiscales les groupes d experts ainsi que les ministeres des finances du gouvernement federal et des gouvernements provinciaux dans le design des politiques fiscales

testing for poverty dominance an application to canada the paper proposes and applies statistical tests for poverty dominance that check for whether poverty comparisons can be made robustly over ranges of poverty lines and classes of poverty indices this helps provide both normative and statistical confidence in establishing poverty rankings across distributions the tests which can take into account the complex sampling procedures that are typically used by statistical agencies to generate household level surveys are implemented using the canadian survey of labour and income dynamics slid for 1996 1999 and 2002 although the yearly cumulative distribution functions cross at the lower tails of the distributions the more recent years tend to dominate earlier years for a relatively wide range of poverty lines failing to take into account slid s sampling variability as is sometimes done can inflate significantly one s confidence in ranking poverty taking into account slid s complex sampling design as has not been done before can also decrease substantially the range of poverty lines over which a poverty ranking can be inferred

the incidence of income taxes on high earners in canada this article explores the brain drain explanation for the concentration of incomes in canada during the past 30 years namely that high skilled canadians make use of high salaries on offer in the united states to extract higher salaries at home if this is the case then for a given level of us salaries the threat to accept outside offers should be more credible when the canadian dollar is depreciating against the us dollar and weaker when the canadian dollar is appreciating the data are broadly consistent with this claim income concentration worsened during the depreciations of the 1980s and 1990s and eased when the canadian dollar began to appreciate in value the article develops a simple two parameter model based on the propositions that high earners in canada can use us salaries to bargain for higher salaries and that canadian high earners can shelter part of their income from personal income taxes it also offers some preliminary evidence about the parameter values consistent with available data the results suggest that higher top marginal personal income tax rates may potentially accentuate top end after tax income inequality if high earners are able to use their bargaining power to extract pay increases to offset higher tax rates then the burden of increased personal income taxes will be deflected elsewhere and may even have the perverse effect of making the after tax income distribution more unequal than it was before l incidence des impots sur le revenu des hauts salaries au canada cet article examine l hypothese des produits de base produits de base produits de base produits de base produits de base fuites des cerveaux comme explication pour la concentration des revenus au canada pendant les dernieres decennees c est a dire que les canadiens hautement qualifies se servent des salaires offerts aux etats unis pour negocier des salaires plus eleves au canada si tel est le cas la menace d emigrer aux etats unis est plus credible lorsque le dollar canadien deprecie contre le dollar americain et elle est moins credible pendant une appreciation les grandes lignes des variations des donnees vont dans le sens de cette conjecture la concentration des revenus a accru pendant les depreciations des annees 1980 et 1990 et cette tendance a renverse la direction suite a l appreciation du dollar canadien l article developpe un modele a deux parametres base sur les propositions que les hauts salaries au canada peuvent utiliser les salaires aux etats unis afin de negocier des salaires plus eleves et que les hauts salaries se servent de la planification fiscale afin de mettre une partie de leurs revenus a l abri des impots des estimations preliminaires pour les parametres sont presentees les resultats suggerent qu une augmentation du taux marginal d imposition pourrait meme accentuer l inegalite des revenus apres impots si les hauts salaries sont capables de negocier des salaires plus eleves face aux augmentations des taux d imposition le fardeau du nouvel impot serait refile ailleurs la distribution des revenus nets pourrait meme devenir encore plus inegale

the evolution of income inequality in rural china abstract in this article we analyze trends in income inequality and the distribution of income in rural china from 1987 to 1999 we find an uneven but long run increase in inequality in rural china and show that nearly half of the rural population was not much better off in 1999 than at the start of the period we rule out geography as the most important factor for explaining income differences and the increases that occurred over time much more important were growing differences between households living in the same village province or region we also find that access to nonagricultural incomes from local wage employment and family businesses contributes to inequality but that employment outside the county in which a household lives and accessed through temporary migration is relatively equalizing finally we document important strengths and weaknesses of the primary data set used for our analyses relative to other data sources available for study of inequality and poverty in rural china

does work experience increase productivity a test of the on the job training hypothesis using data on wage claims investigations of a state labor department we test the proposition that work experience increases productivity productivity is measured as the fraction of wages an employer allegedly owes an employee which the investigator is able to collect the recovery of back wages is accomplished without the availability of an official enforcement mechanism the empirical estimates indicate that investigators become significantly more productive during the first six years of job experience while the uniqueness of this occupation prevents generalizing this finding the study raises some important methodological issues

taxation and executive compensation evidence from stock options abstract understanding the effects of taxes on executive compensation provides insight into the process determining this compensation and is a key input to top income tax rate policy a 2010 tax reform in canada which greatly increased the effective tax rate on stock option compensation for a subset of firms provides a natural experiment with which to address this issue difference in differences estimates suggest that this tax increase resulted in an immediate reduction in both stock option grants and the fraction of total compensation made up of stock options with limited if any substitution towards other components of compensation

estimating labour supply responses using tax reforms the 1980 s tax reforms and the changing dispersion of wages offer one of the best opportunities yet to estimate labor supply effects nevertheless changing sample composition aggregate shocks the changing composition of the tax paying population and discontinuities in the tax system create serious identification and estimation problems we develop grouping estimators that address these issues our results reveal positive and moderately sized wage elasticities we also find negative income effects for women with children

robust comparative statics in large dynamic economies we consider infinite horizon economies populated by a continuum of agents subject to idiosyncratic shocks this framework contains models of saving and capital accumulation with incomplete markets in the spirit of works by bewley aiyagari and huggett models of entry exit and industry dynamics in the spirit of hopenhayn s work and dynamic models of occupational choice and search models as special cases robust and easy to apply comparative statics results are established with respect to exogenous parameters as well as various kinds of changes in the markov processes governing the law of motion of the idiosyncratic shocks

the credibility revolution in empirical economics how better research design is taking the con out of econometrics since edward leamer s memorable 1983 paper let s take the con out of econometrics empirical microeconomics has experienced a credibility revolution while leamer s suggested remedy sensitivity analysis has played a role in this we argue that the primary engine driving improvement has been a focus on the quality of empirical research designs the advantages of a good research design are perhaps most easily apparent in research using random assignment we begin with an overview of leamer s 1983 critique and his proposed remedies we then turn to the key factors we see contributing to improved empirical work including the availability of more and better data along with advances in theoretical econometric understanding but especially the fact that research design has moved front and center in much of empirical micro we offer a brief digression into macroeconomics and industrial organization where progress by our lights is less dramatic although there is work in both fields that we find encouraging finally we discuss the view that the design pendulum has swung too far critics of design driven studies argue that in pursuit of clean and credible research designs researchers seek good answers instead of good questions we briefly respond to this concern which worries us little

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

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

is job insecurity on the rise evidence from canadian perception data this paper examines the unexplored issue of worker insecurity perception in canada specifically we explore for changes in worker perceptions of job security using canadian gallup data for the 1977 2006 period we find that the high levels of perceived insecurity of the early to mid 1990s were only cyclical in nature not evidence of structural change we also explore for differences across socio economic groups and find that university educated workers full time workers and white collar workers all felt relatively more secure about present and future job prospects interestingly union members tend to be more concerned about job security than non union ce memoire examine le probleme inexplore de la perception de la precarite de l emploi au canada specifiquement on explore les changements dans les perceptions de precarite d emploi des travailleurs a l aide de donnees gallup pour la periode 1977 2006 il appert que les hauts niveaux de precarite percue du debut au milieu des annees 90 etaient de nature cyclique et non pas le resultat d un changement structurel on examine aussi les differences entre groupes socio economiques et on decouvre que les travailleurs avec une formation universitaire les travailleurs a temps plein et les collets blancs se sentaient relativement plus en securite quant aux perspectives d emploi presentes et futures il est interessant de noter que les travailleurs syndiques sont davantage inquiets quant a la precarite de l emploi que les non syndiques

why have poorer neighbourhoods stagnated economically while the richer have flourished neighbourhood income inequality in canadian cities higher income neighbourhoods in canada s eight largest cities flourished economically during the past quarter century while lower income communities stagnated this paper identifies some of the underlying processes that led to this outcome increasing family income inequality drove much of the rise in neighbourhood inequality increased spatial economic segregation the increasing tendency of like to live nearby like also played a role it is shown that these changes originated in the labour market changes in investment pension income and government transfers played a very minor role yet it was not unemployment that differentiated the richer from poorer neighbourhoods rather it was the type of job found particularly the annual earnings generated the end result has been little improvement in economic resources in poor neighbourhoods during a period of substantial economic growth and a rise in neighbourhood income inequality

on the existence and uniqueness of stationary equilibrium in bewley economies with production abstract i prove existence of stationary recursive competitive equilibrium in bewley economies with production under specifications in which i the utility function is allowed to be unbounded and ii the underlying discrete idiosyncratic productivity process can take any form aside from mild restrictions some of the intermediate results provide theoretical basis for assumptions often made in the quantitative macroeconomics literature by providing an example i illustrate that the equilibrium is not necessarily unique even under typical specifications of the model and discuss the underlying reasons for multiplicity

do taxes matter the impact of the tax reform act of 1986 do taxes matter is the first systematic examination of the actual effects of the tax reform act of 1986 the most important u s income tax reform of the last four decades it presents basic information on and an analysis of a variety of different aspects of economic behavior in order to discover whether the observed changes coincide with the predictions of standard public finance models prior to implementation of the new law supporters and opponents made numerous forecasts about its effect on savings corporate investment and other major determinants of the country s economic health the general finding of these original contributions is that the effects of tax reform turned out to be smaller than had been anticipated commissioned by the office of tax policy research of the university of michigan eight of the studies focus on different sectors of the economy reviewing the predictions and carefully analyzing the evidence to determine actual effects the ninth study draws together the results to find lessons for future changes in tax policy joel slemrod is professor of business economics and public policy and director of the office of tax policy research at the university of michigan contents the economic impact of tax reform act of 1986 joel slemrod investment tax policy and the tax reform act of 1986 alan j auerbach kevin hassett the impact of the 1986 tax reform on personal saving jonathan skinner daniel feenberg effects of the tax reform act of 1986 on corporate financial policy and organizational form roger h gordon jeffrey k mackie mason taxation and housing markets preliminary evidence on the effects of recent tax reforms james m poterba the impact of the tax reform act of 1986 on foreign direct investment to and from the united states joel slemrod the impact of tax reform on charitable giving a 1989 perspective charles t clotfelter the impact of the tax reform act of 1986 on state and local fiscal behavior paul n courant edward m gramlich foreign responses to u s tax reform john whalley lessons for tax reform henry j aaron

the effect of marginal tax rates on taxable income a panel study of the 1988 tax flattening in canada abstract federal tax reform in 1988 flattened the canadian personal income tax schedule changing the marginal tax rates for many individuals using methods similar to those applied by auten and carroll rev econ 81 4 1999 681 in the study of the effects of the 1986 u s tax reform act we estimate the responsiveness of income to changes in taxes to be substantially smaller in canada however we find evidence of a much higher response in self employment income in the labor income of seniors and from those with high incomes

the elasticity of taxable income with respect to marginal tax rates a critical review this paper critically surveys the large and growing literature estimating the elasticity of taxable income with respect to marginal tax rates using tax return data first we provide a theoretical framework showing under what assumptions this elasticity can be used as a sufficient statistic for efficiency and optimal tax analysis we discuss what other parameters should be estimated when the elasticity is not a sufficient statistic second we discuss conceptually the key issues that arise in the empirical estimation of the elasticity of taxable income using the example of the 1993 top individual income tax rate increase in the united states to illustrate those issues third we provide a critical discussion of selected empirical analyses of the elasticity of taxable income in light of the theoretical and empirical framework we laid out finally we discuss avenues for future research jel h24 h31 j22

incomplete markets labor supply and capital accumulation we explore the accumulation of capital in the presence of limited insurance against idiosyncratic shocks borrowing constraints and endogenous labor supply in the exogenous labor supply case e g aiyagari 1994 huggett 1997 the presence of limited insurance increases the demand for savings for precautionary reasons as a consequence capital and output are higher under incomplete markets we show that if labor hours are endogenous labor supply is likely to be lower under incomplete markets because those agents who experience a high shock to productivity are ex post richer and they work fewer hours in some cases this wealth effect can overcome the aggregate precautionary savings and give rise to lower savings and output under incomplete

recursive equilibria in an aiyagari style economy with permanent income shocks in this paper we prove the existence of a recursive competitive equilibrium rce for an aiyagari style economy with permanent income shocks and perpetual youth structure we show that there exist equilibria where borrowing constraints are never binding this allows us to establish a non trivial lower bound on the equilibrium interest rate to solve the individual s problem we present a new approach that uses lattices of consumption functions to deal with the non compact state space and the unbounded utility function the approach uses only the first order conditions of the problem euler equations the proof is constructive and it serves as a theoretical foundation for the convergence of a policy function iteration procedure

the effect of marginal tax rates on taxable income a panel study of the 1986 tax reform act this paper uses a treasury department panel of more than 4 000 taxpayers to estimate the sensitivity of taxable income to changes in tax rates on the basis of a comparison of the tax returns of the same individual taxpayers before and after the 1986 tax reform the analysis emphasizes that the response of taxable income involves much more than a change in the traditional measures of labor supply the evidence shows an elasticity of taxable income with respect to the marginal net of tax rate that is at least one and could be substantially higher the implications for recent tax rate changes are discussed

why have the labor force participation rates of older men increased since the mid 1990s this article seeks to explain the substantial increases in older men s labor force participation rates observed since the mid 1990s using data from the united states canada and the united kingdom i exploit the cohort effects driving recent increases in older women s participation rates to identify the effect of a wife s participation decision on her husband s participation decision i then decompose the changes in older married men s participation rates demonstrating that husbands responses to increases in wives participation in the labor force can explain one fourth one half and one third of the increase in the united states canada and the united kingdom respectively

optimal consumption policy under uncertain income this paper considers the consumption behavior of a risk averse consumer with a preference for immediate consumption who faces an uncertain income stream and plans for a finite or infinite number of periods the consumer may borrow up to a limit or save where both saving and borrowing are subject to the same positive rate of interest we derive the optimal consumption policies for both finite and infinite planning horizons investigate their characteristics and analyze their economic and behavioral implications

the effect of income taxes on household income research on the distribution of income during the 1980s has identified a trend towards increasing inequality which may be the continuation and acceleration of trends spanning several decades this paper explores to what extent behavioral responses to the tax changes during the 1980s may also explain the rising inequality the 1986 tax reform act is used as a natural experiment to explore the roles played by both taxes and a variety of nontax factors our principal finding is that both tax rates and nontax factors appear to have had significant effects on relative income growth during the late 1980s

top incomes in the long run of history a recent literature has constructed top income shares time series over the long run for more than twenty countries using income tax statistics top incomes represent a small share of the population but a very significant share of total income and total taxes paid hence aggregate economic growth per capita and gini inequality indexes are sensitive to excluding or including top incomes we discuss the estimation methods and issues that arise when constructing top income share series including income definition and comparability over time and across countries tax avoidance and tax evasion we provide a summary of the key empirical findings most countries experience a dramatic drop in top income shares in the first part of the twentieth century in general due to shocks to top capital incomes during the wars and depression shocks top income shares do not recover in the immediate postwar decades however over the last thirty years top income shares have increased substantially in english speaking countries and in india and china but not in continental european countries or japan this increase is due in part to an unprecedented surge in top wage incomes as a result wage income comprises a larger fraction of top incomes than in the past finally we discuss the theoretical and empirical models that have been proposed to account for the facts and the main questions that remain open

on income fluctuations and capital gains abstract we consider the infinite time horizon problem of asymptotically maximizing the expected accumulated discounted utility in a one good production economy the available capital in a given period is given by the production of the previous period plus a random variable the product of the discount and interest factors is either 1 greater than or 2 equal to one under 1 the optimal policy exists under certain conditions and always under 2 the optimal capital sequence almost surely goes to infinity under 1 with conditions on the utility one almost surely reaches a capital level above which the sequence is increasing

consumption liquidity constraints and asset accumulation in the presence of random income fluctuations recent empirical research flavin 1981 hagashi 1982 has rejected the certainty equivalent formulation of permanent income hypothesis hall 1978 these findings are often attributed to households inability to borrow completely against expected future labor income this paper is a theoretical investigation of optimal consumption behavior under risk aversion random income fluctuations and borrowing restrictions our principle objective is to establish the existence and to investigate the properties of the stationary probability distribution which characterizes the asymptotic behavior of consumption under these conditions this abstract was borrowed from another version of this item

hourly wage rate and taxable labor income responsiveness to changes in marginal tax rates recently a voluminous literature estimating the taxable income elasticity has emerged as an important field in empirical public economics however to a large extent it is still unknown how the hourly wage rate an important component of taxable income reacts to changes in marginal tax rates in this study we use a rich panel data set and a sequence of tax reforms that took place in sweden during the 1980 s to estimate the elasticity of the hourly wage rate with respect to the net of tax rate while carefully accounting for the endogeneity of marginal tax rates as well as other factors that determine wage rates we do find a statistically significant response both among married men and married women the hourly wage rate elasticity with respect to the net of tax rate is estimated to 0 14 0 16 for males and 0 41 0 57 for females in addition we obtain uncompensated taxable labor income elasticities of around 0 21 for men and 0 96 1 44 for women in contrast to earlier studies we also find significant income effects for males accordingly for males the compensated taxable labor income elasticity is about 4 percentage points higher than the uncompensated one

marital sorting inequality and the role of female labor supply evidence from east and west germany this paper examines to what extent marital sorting affects cross sectional earnings inequality in germany over the past three decades while explicitly taking into account labor supply choices using rich micro data the observed distribution of couples earnings is compared to a counterfactual of randomly matched spouses hypothetical earnings are predicted based on a structural model of household labor supply for west germany a positive effect of marital sorting on inequality is found after adjusting for labor supply behavior while the effect is limited when earnings are taken as given this means that there is positive sorting in earnings potential which is veiled by relatively low female labor force participation in east germany the impact of marital sorting on inequality is highly disequalizing irrespective of adjusting for labor supply choices this is mainly due to the fact that east german women are much more attached to the labor market

what happens when you tax the rich evidence from executive compensation this paper examines the responsiveness of taxable income to changes in marginal tax rates using detailed compensation data on several thousand corporate executives from 1991 to 1995 the data confirm that the higher marginal rates of 1993 led to a significant decline in taxable income indeed this small group of executives may account for as much as 20 percent of the aggregate change in wage and salary income for approximately the one million richest taxpayers over this time period one person alone can account for more than 2 percent the decline however is almost entirely a short run shift in the timing of compensation rather than a permanent reduction in taxable income the short run elasticity of taxable income with respect to the net of tax share exceeds one in this sample but the elasticity after one year is at most 0 4 and probably closer to zero breaking out the tax responsiveness of different types of compensation shows that the large short run responses come almost entirely from a large inc

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

tax avoidance and the deadweight loss of the income tax traditional analyses of the income tax greatly underestimate deadweight losses by ignoring its effect on forms of compensation and patterns of consumption the full deadweight loss is easily calculated using the compensated elasticity of taxable income to changes in tax rates because leisure excludable income and deductible consumption are a hicksian composite good microeconomic estimates imply a deadweight loss of as much as 30 of revenue or more than ten times harberger s classic 1964 estimate the relative deadweight loss caused by increasing existing tax rates is substantially greater and may exceed 2 per 1 of revenue

the integration of child tax credits and welfare evidence from the national child benefit program abstract in 1998 the canadian government introduced a new child tax credit the innovation in the program was its integration with social assistance welfare some provinces agreed to subtract the new federally paid benefits from provincially paid social assistance partially lowering the welfare wall other provinces did not integrate benefits providing a quasi experimental framework for estimation we find large changes in social assistance take up and employment in provinces that provided the labour market incentives to do so in our sample the integration of benefits can account for between 19 and 27 of the decline in social assistance receipt between 1997 and 2000

tax bases tax rates and the elasticity of reported income abstract tax reforms usually change both tax rates and tax bases using a panel of income tax returns spanning the two major u s tax reforms of the 1980s and a number of smaller tax law changes i find that the elasticity of income reported on personal income tax returns depends on the available deductions this highlights that this key behavioral elasticity is not an immutable parameter but rather that it can be to some extent controlled by policy makers one implication is that base broadening reduces the marginal efficiency cost of taxation the results are very similar for all income categories indicating that the rich are more responsive to tax rates because tax rules that apply to them are different their tax base is narrower the point estimates indicate that the tax reform act of 1986 reduced the marginal cost of collecting a dollar of tax revenue with roughly half of this reduction due to the base broadening and the other half due to the tax rate reduction as a by product the analysis in this paper offers a reconciliation of disparate estimates obtained by previous studies of the tax responsiveness of income

taxation and top incomes in canada we estimate the elasticity of reported income with respect to tax rates for high earners using sub national variation across canadian provinces we argue this allows for better identification of tax elasticities than the existing literature we find that elasticities of reported income at the provincial level are large for incomes in the top 1 but small for lower earners there are strong indications that the response happens both through earned and capital income while our estimated elasticities are large changes in tax rates cannot explain much of the overall long run trend of higher income concentration in canada resume fiscalite et revenus les plus eleves au canada les auteurs evaluent l elasticite du revenu declare par rapport aux taux d imposition pour les revenus les plus eleves en utilisant les variations intra nationales a travers les provinces du canada ils suggerent que cela produit une meilleure identification des elasticites que ce que contient la litterature pour le moment on decouvre que les elasticites du revenu declare sont elevees pour les 1 au sommet mais faibles pour les revenus plus bas il appert fortement que la reponse se produit tant pour les revenus gagnes que pour les revenus d investissement meme si les elasticites mesurees sont elevees les changements dans les taux d imposition ne peuvent pas expliquer beaucoup de la tendance a long terme vers une plus forte concentration des hauts revenus au canada

reported gross income and marginal tax rates estimation of the behavioural reactions of spanish taxpayers this article estimates for the spanish personal income tax the elasticity of reported gross income to marginal tax rates the identification of this elasticity has been performed using the reform approved by law 35 2006 which came into force in january 2007 the elasticities obtained suggest the existence of important efficiency costs with significant regional differences the average elasticity estimated for spain as a whole is 0 676 however this elasticity is highly dispersed throughout the spanish administrative regions which indicates the unequal power of distortion of the tax thus households whose principal source of income is salary display an elasticity of 0 337 compared to 0 682 for households whose main income source comes from business or savings lastly a positive correlation is also detected between elasticity and income level an elasticity of 3 6 is reached for taxpayers with an annual gross income exceeding 100 000

growing unequal changes in the distribution of earnings across canadian cities this paper investigates changes in the distribution of earnings across 87 metropolitan areas in canada it does so using micro data taken from the 20 per cent long form sample of the census for the years 1996 2001 and 2006 results point to overall increases in urban inequality and to greater heterogeneity in inequality across the urban hierarchy with larger cities growing particularly unequal over time cross sectional and panel regression models suggest that city size unemployment deindustrialisation and the percentage of a city s population composed of visible minorities contribute to increased inequality in contrast a city s level of economic development has a mitigating effect on inequality although this effect appears to fade away over time the effects of changes in a city s age education and gender profiles on inequality are mixed

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

when do borrowing constraints bind some new results on the income fluctuation problem abstract the empirical failure of the permanent income hypothesis has prompted researchers to investigate models in which consumers are liquidity constrained as shown in deaton econometrica 59 5 1991 1221 liquidity constrained consumers might choose to exhaust their borrowing capacity from time to time yet due to technical limitations the conditions under which this behavior arises have not been investigated the present paper extends the class of solvable models in a way that allows this issue to be dealt with it turns out that under the loosest sustainable borrowing constraint the agent might systematically avoid exhausting his borrowing capacity

viewpoint measuring the well being of the poor with income or consumption a canadian perspective there is a long tradition of using consumption measures derived from statistics canada s household expenditures surveys to study material well being inequality and poverty we offer an introduction to this research income and consumption measures give different pictures of the patterns of material well being in canada but the differences are not as large as in the us we also provide a comparison to meyer and sullivan s results on data quality canadian expenditure surveys are of high quality unique aspects of these surveys variation in quality control measures over time and the possibility of comparing to income tax data provide important insights into the quality of survey data on income and consumption il existe une longue tradition d utilisation de mesures de consommation derivees de l enquete des depenses des menages de statistiques canada pour mesurer le bien etre materiel l inegalite et la pauvrete les auteurs presentent ces recherches les mesures de revenus et de consommation donnent des portraits differents des patterns de bien etre materiel au canada mais les differences ne sont pas aussi importantes qu aux etats unis on presente une comparaison avec les resultats de meyer et sullivan sur la qualite des donnees les enquetes sur les depenses sont de haute qualite au canada certains aspects uniques de ces enquetes variation dans les mesures de controle de qualite dans le temps et possibilite de comparer les donnees derivees des rapports d impot sur le revenu fournissent des apercus importants sur la qualite des donnees d enquetes sur le revenu et la consommation canadian economics association

international lending and borrowing in a stochastic stationary equilibrium this paper develops a simple general equilibrium model of international borrowing and lending in which national products are subject to random fluctuations international capital flows arise from the efforts of risk averse households in different countries to self insure against random income fluctuations by accumulating foreign claims that can be used to finance a less variable profile of consumption relative to national income in the absence of aggregate uncertainty a stationary rational expectations equilibrium is shown to exist despite the fact that rates of time preference differ among countries a number of results many of which enrich those in the existing literature are obtained copyright 1990 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

cohort patterns in canadian earnings assessing the role of skill premia in inequality trends in this paper we document the pattern of change in age earnings profiles across cohorts and evaluate its implications using synthetic cohorts from the survey of consumer finances over the period 1971 to 1993 wwe show that the age earnings profiles of canadian men have been deteriorating for more recentcohorts in comparison with older cohorts we find this pattern for both high school and university educated workers in no case do we find evidence that the return to gaining experience has been increasing over time nor do we find increased within cohort dispersion of earnings we view these findings as conflicting with the hypothesis that increased skill premia largely explain the observed increase in dispersion of male weekly earnings jel classification j31 o33 ce memoire documente le pattern de changements dans les relations ges gains d une cohorte a l autre et en analyse les implications utilisant des cohortes synthetiques pour la periode 1971 93 on montre que les profils ges gains des hommes au canada se sont deteriores dans les cohortes les plus recentes on ne trouve pas de resultats qui montreraient que le rendement sur l experience accumulee s est accru dans le temps ou qu il y a dispersion accrue des gains a l interieur des cohortes les auteurs suggerent que ces resultats contredisent l hypothese que des primes accrues pour les habiletes expliqueraient l accroissement qu on a observe dans la dispersion des gains des hommes au canada

did tax flattening affect rrsp contributions in 1988 marginal personal income tax rates changed in canada for some individuals by reasonably substantial amounts in this note a large sample of tax filer data is examined and the conclusion is drawn that when attention is paid to the possible confounding of marginal tax rate and non linear income effects there is no convincing evidence that the tax rate changes affected contributions to registered retirement saving plans rrsps est ce que l aplatissement des taux d imposition influence les contributions au reer en 1988 les taux marginaux d imposition du revenu personnel ont change au canada et pour certaines personnes ces changements ont ete substantiels cette note examine un grand echantillon de rapports d impots et en arrive a la conclusion que quand on prend en compte le melange possible des effets du taux marginal d imposition et des effets de revenu non lineaires il n y a pas de resultats qui montrent de facon probante que les changements dans les taux d imposition ont influence les contributions au reer
