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

taxation and international migration of superstars evidence from the european football market we analyze the effects of top tax rates on international migration of football players in 14 european countries since 1985 both country case studies and multinomial regressions show evidence of strong mobility responses to tax rates with an elasticity of the number of foreign domestic players to the net of tax rate around one around 0 15 we also find evidence of sorting effects low taxes attract highability players who displace low ability players and displacement effects low taxes on foreigners displace domestic players those results can be rationalized in a simple model of migration and taxation with rigid labor demand jel f22 h24 h31 j44 j61 l83

a model of demand with interactions among consumers abstract the aim of this paper is to study emergent patterns of demand when there are social interactions between different consumers specifically our concern is with the case in which consumers preferences are influenced by the consumption behaviour of others the analysis recognises three reference groups the first is a peer group of similar consumers with whom the individual interacts on a regular basis and with whom the individual desires to share some consumption activities the second is one or several contrast group s with which the individual seeks actively not to interact and from whom the individual wishes to distinguish himself herself the third is an aspirational group with whom the individual does not interact on a regular basis but wishes that he she did and with whom the individual would like to share consumption activities but cannot in this relatively simple model these groups influence the individual s behaviour the paper derives steady state and dynamic properties of the distribution of consumption over users the degree to which consumption is restricted to a small group of similar agents is determined by the strength of the contrast and aspiration effects these effects also drive the distribution away from the natural distribution i e the one that would prevail were consumers to consider only the properties of the good and not the actions of other consumers the paper discusses the potential application of this modeling framework in a large number of consumption settings

the incidence of personal income taxation evidence from the tax reform act of 1986 abstract this paper studies the short run incidence of personal income taxation in the us by examining how the wage structure shifted after the tax reform act of 1986 i calculate the marginal tax rate for the median worker of each occupation during the 1980s to determine the professions whose workers were most affected by the tax change when controlling for trends over time in the wage structure by occupation i find that individuals in occupations that experienced large decreases in their median marginal tax rates received lower pre tax wages after 1986 as the number of workers and the hours worked in those professions increased the results suggest that consideration of the wage effects of tax reforms is important when using these reforms to identify behavioral parameters and evaluating their distributional consequences

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

the long run determinants of inequality what can we learn from top income data this paper studies determinants of income inequality using a newly assembled panel of 16 countries over the entire twentieth century we focus on three groups of income earners the rich p99 100

social networks and new product choice to successfully market new products in a social network it is essential to identify influential individuals whose product recommendations influence the consumption choices of their peers in this study we use spatial econometric methods to determine how individuals revise their preferences for product attributes when exposed to product recommendations from peers and how different individuals who vary in their degree of network connectedness exert influence on the product choices of others we find evidence that consumers look to others for guidance from peers in their preference for subjective taste specific parameters but tend not to respond to peer price choices our spatial methods allow us to empirically determine the influence exerted by individual members on the consumption choices of other members of the social network we find that connected members of the social network are not always the most influential in revising the consumption choices of others our estimates reveal that network proximity explains only 8 8 of influence

bounds on elasticities with optimization frictions a synthesis of micro and macro evidence on labor supply how can price elasticities be identified when agents face optimization frictions such as adjustment costs or inattention i derive bounds on structural price elasticities that are a function of the observed effect of a price change on demand the size of the price change and the degree of frictions the degree of frictions is measured by the utility losses agents tolerate to deviate from the frictionless optimum the bounds imply that frictions affect intensive margin elasticities much more than extensive margin elasticities i apply these bounds to the literature on labor supply the utility costs of ignoring the tax changes used to identify intensive margin labor supply elasticities are typically less than 1 of earnings as a result small frictions can explain the differences between micro and macro elasticities extensive and intensive margin elasticities and other disparate findings pooling estimates from existing studies i estimate a hicksian labor supply elasticity of 0 33 on the intensive margin and 0 25 on the extensive margin after accounting for frictions

micro and macro labor supply elasticities a reassessment of conventional wisdom the response of aggregate labor supply to various changes in the economic environ ment is central to many economic issues especially the optimal design of tax policies conventional wisdom based on studies in the 1980s and 1990s has long held that the analysis of micro data leads one to conclude that aggregate labor supply elasticities are quite small in this paper we argue that this conventional wisdom does not hold up to empirically reasonable and relevant extensions of simple life cycle models that served as the basis for these conclusions in particular we show that several pieces of conventional wisdom fail in the presence of human capital accumulation or labor supply decisions that allow for adjustment along both the extensive and intensive margin we conclude that previous estimates of small labor supply elasticities based on micro data are fully consistent with large aggregate labor supply elasticities jel d91 e24 j22

modeling interdependent consumer preferences abstract a consumer s preference for an offering can be influenced by the preferences of others in many ways ranging from social identification and inclusion to the benefits of network externalities in this article the authors introduce a bayesian spatial autoregressive discrete choice model to study the preference interdependence among individual consumers the autoregressive specification can reflect patterns of heterogeneity in which influence propagates within and across networks these patterns cannot be modeled with standard random effect specifications and can be difficult to capture with covariates in a linear model the authors illustrate their model of interdependent preferences with data on automobile purchases and show that preferences for japanese made cars are related to geographically and demographically defined networks

innovation diversity and diffusion a self organisation model a number of features of innovation diffusion are identified appropriability diversity expectations selection learning and spillover externalities a dynamic model is formul ated to embed the diffusion question into a more general framework of disequilibrium competition the model incorporates distinct vintage structures reflecting a change in technological trajectory learning by using a nd expectations driven investment rules of thumb simulation studies reveal robust quasi logistic curves but a complicated pattern of net market share gains and losses uncertainty regarding the rationality of early or late adoption it is argued ensures that the requisite behavioral variety is present to generate these diffusion patterns copyright 1988 by royal economic society

measuring permanent responses to capital gains tax changes in panel data the authors use panel data and information about differences in state tax rates to separate the effects of transitory and permanent tax rate changes on capital gains realizations behavior the estimated effect of permanent change is substantially smaller than the effect of transitory change the difference is even larger than differences between estimates from past micro data studies which have primarily measured the transitory effect and time series studies which have primarily measured the permanent effect the authors results resolve a long standing conflict between micro data and time series studies of how marginal tax rates affect capital gains realizations behavior copyright 1994 by american economic association

the optimal elasticity of taxable income abstract the strength of the behavioral response to a tax rate change depends on the environment individuals operate in and may be manipulated by instruments controlled by the government we first derive a measure of the social benefit to affecting this elasticity the paper then examines this effect in the solution to the optimal income taxation problem when such an instrument is available first in a general model and then in an example when the government chooses the income tax base

waves in consumption with interdependence among consumers this paper presents a model to analyze the development of consumption patterns when there are social interactions among consumers in particular a consumer in this model recognizes three reference groups a peer group of similar consumers with whom the consumer wishes to share consumption activities a distinction group from which the consumer wishes to distinguish him or herself and an aspiration group to which the consumer does not belong but wishes that he she did and with whom the consumer would like to share consumption activities the interplay of aspiration and distinction can lead to waves in consumption these can happen when for example the avant garde consumption of up market pioneers is copied by other types of consumer as the latter aspire to emulate the former the former in turn seek to distinguish themselves from these unwelcome companions by varying their consumption in consequence a particular consumption activity may start up market an then gradually proceed down the social spectrum more complex patterns with continuing cycles in consumption can also be found the paper argues that this model is not only applicable to the consumption behaviour of an elite or would be elite but is relevant in a wide range of consumption settings

corporate dollar debt and depreciations much ado about nothing abstract emerging markets firms often carry foreign currency debt on their balance sheets following a depreciation the expanding peso value of dollar liabilities could via a net worth effect offset the expansionary competitiveness effect to assess which effect dominates we use accounting data including the currency composition of liabilities for 450 nonfinancial firms in five latin american countries in the 1990s we find that firms holding more dollar debt do not invest less than their peso indebted counterparts following a depreciation we also show that these firms match the currency denomination of their liabilities with the exchange rate sensitivity of their profits

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

toward obtaining a consistent estimate of the elasticity of taxable income using difference in differences abstract the elasticity of taxable income eti is a central parameter for tax policy debates this paper shows that mean reversion prevents most estimators employed in the literature from obtaining consistent estimates of the eti a new method is proposed that will resolve inconsistency due to mean reversion under testable assumptions regarding the degree of serial correlation in the error term using this procedure i estimate an eti of 0 858 which is about twice as large as the estimates found in the most frequently cited paper on this subject 13 the corresponding elasticity of broad income is 0 475

conspicuous consumption and race evidence from south africa abstract a century ago thorstein veblen introduced socially contingent consumption into the economic literature this paper complements the scarce empirical literature by testing his conjecture on south african household data and finds that black and coloured households spend relatively more on visible consumption than comparable white households following the approach of charles et al 2009 this paper explores whether the differences in visible expenditures can be explained with a signaling model of status seeking moreover it is assessed to which extent positional concerns motivate conspicuous consumption although the socially contingent share in visible consumption increases with income different incentives to consume conspicuously seem to explain that at every level of income black households spend relatively more on visible consumption than comparable white households in contrast to the findings of charles et al 2009 where differential spending on conspicuous consumption can be found also within each group separately the model s core hypothesis fails to hold within the group of white south africans

a theory of rational addiction we develop a theory of rational addiction in which rationality means a consistent plan to maximize utility over time strong addiction to a good requires a big effect of past consumption of the good on current consumption such powerful complementarities cause some steady states to be unstable they are an important part of our analysis because even small deviations from the consumption at an unstable steady state can lead to large cumulative rises over time in addictive consumption or to rapid falls in consumption to abstention our theory also implies that cold turkey is used to end strong addictions that addicts often go on binges that addicts respond more to permanent than to temporary changes in prices of addictive goods and that anxiety and tensions can precipitate an addiction

the optimal treatment of tax expenditures abstract this paper analyzes the optimal treatment of tax expenditures it develops an optimal tax model where individuals derive utility from spending on a contribution good such as charitable giving the contribution good has also a public good effect on all individuals in the economy the government imposes linear taxes on earnings and on the contribution good so as to maximize welfare the government may also finance directly the contribution good out of tax revenue optimal tax and subsidy rates on earnings and the contribution good are expressed in terms of empirically estimable parameters and the redistributive tastes of the government the optimal subsidy on the contribution good is increasing in the size of the price elasticity of contributions the size of the crowding out effect of public contributions on private contributions and the size of the public good effect of the contribution good numerical simulations show that the optimal subsidy on contributions is fairly sensitive to the size of these parameters but that in most cases it should be lower than the earnings tax rate

tortoises and hares choice among technologies of unknown merit recent work in the area of competing technologies and increasing returns has largely been concerned with the effectiveness of the market in delivering optimal outcomes the existence of inefficient market outcomes suggests that there might be a place for intervention in the technology choice process this paper develops a model of sequential choice in which the choice process is subject to centralized control the model is used to show that intervention can increase the expected present value of the technology adoption process it remains however that one technology and not necessarily the best will come to dominate the market copyright 1991 by royal economic society

trade credit and the propagation of corporate failure an empirical analysis using an exhaustive data set on claims held by trade creditors suppliers on failed trade debtors customers we quantify the importance of trade credit chains for the propagation of corporate bankruptcy we show that trade creditors experience significant trade credit losses due to trade debtor failures and that creditors bankruptcy risks increase in the size of incurred losses by exploring the roles of financial constraints and creditor debtor dependences we infer that the trade credit failure propagation mechanism is driven by both credit losses and demand shrinkage finally we show that the documented propagation mechanism constitutes a significant part of the overall bankruptcy frequency suggesting that it has measurable implications for the aggregate level

do real exchange rate appreciations matter for growth the impact of exchange rate changes on growth a long standing key issue in international macroeconomics has received renewed attention in recent years owing to weaker growth rates and the debate on currency wars the connection between real exchange rates and growth remains however an unsettled question in the academic literature we fill this gap by providing an empirical assessment based on a broad sample of emerging and advanced economies we assess the impact of appreciations productivity booms and capital inflows surges using a propensity score matching approach to address causality issues appreciations associated with higher productivity have a larger impact on growth than those associated with capital inflows furthermore appreciations per se tend to have a negative impact on growth we provide a simple theoretical model that delivers a contrasted growth appreciation pattern depending on the underlying shock the model also implies adverse effects of shocks to international capital flows so concerns about an appreciation are not inconsistent with concerns about a depreciation while the presence of an externality through firms destruction leads to inefficient allocations addressing the inefficiency does not dampen exchange rate movements

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

spillovers stratification and inequality this paper surveys some recent work which seeks to model persistent income inequality and explain such phenomena as ghetto formation and poverty traps the paper illustrates how a number of these models possess a common structure in which local spillover effects interact with income based stratification of neighborhoods to transmit parental economic status from generation to generation as such these models represent an extension of the macroeconomic literature on spillovers and coordination failures to economic environments which endogenize the interaction environments of individual agents the theoretical and empirical justifications of these spillover and stratification effects are discussed finally some empirical implications of these models are analyzed

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

threshold models of interpersonal effects in consumer demand abstract whether one buys may be determined in part by how many others have when the correlation is positive we refer to bandwagon effects and when negative reverse bandwagons we construct demand schedules in the presence of such effects and with simple assumptions about supply investigate the existence of and approach to equilibrium stable price quantity equilibria exist but for many plausible parameter values equilibria are asymptotically unstable and system trajectories consist of cycles that can move with slight parameter changes via successive bifurcations into what has been called chaotic dynamics essentially indistinguishable from random noise these conditions occur despite assumptions of erfect information profit maximizing firms and utility maximizing individuals

novelty preferences and fashion when goods are unsettling abstract there is a whole class of goods those semi durable and durable conveniences for which efficiency and functionality seem not to be the main characteristics of appeal but rather the variability they display in their design properties and in their connections with other goods these goods have not been much dealt with in economics yet these are the goods whose new variants households seem to consume in numbers to which consumers become addicted and in which fashions appear and disappear in this paper i offer a framework for understanding these phenomena without having to resort to one or another form of irrationality on the part of consumers the rationality i suggest however has to include also the cognitive and affective problems that arise when novelty appears

consumer behaviour with environmental and social externalities implications for analysis and policy in this paper we summarise some of our recent work on consumer behaviour drawing on recent developments in behavioural economics particularly linked to sociol ogy as much as psychology in which consumers are embedded in a social context so their behaviour is shaped by their interactions with other consumers for the purpose of this paper we also allow consumption to cause environmental damage analysing the social context of consumption naturally lends itself to the use of game theoretic tools we shall be con cernedwithtwowaysinwhichsocialinteractionsaffectconsumerpreferencesandbehaviour socially embeddedpreferences wherethebehaviourofotherconsumersaffectanindividual s preferences and hence consumption we consider two examples conspicuous consumption and consumption norms and socially directed preferences where people display altruistic behaviour our aim is to show that building links between sociological and behavioural eco nomic approaches to the study of consumer behaviour can lead to significant and surprising implications for conventional economic analysis and policy prescriptions especially with respect to environmental policy

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

corporate debt firm size and financial fragility in emerging markets abstract the post global financial crisis period shows a surge in corporate leverage in emerging markets and a number of countries with deteriorated corporate financial fragility indicators altman s z score firm size plays a critical role in the relationship between leverage firm fragility and exchange rate movements in emerging markets while the relationship between firm leverage and distress scores varies over time the relationship between firm size and corporate vulnerability is relatively time invariant all else equal large firms in emerging markets are more financially vulnerable and also systemically important consistent with the granular origins of aggregate fluctuations in gabaix 2011 idiosyncratic shocks to the sales growth of large firms are positively and significantly correlated with gdp growth in our emerging markets sample relatedly the negative impact of exchange rate shocks has a more acute impact on the sales growth of the more highly levered large firms

dynamic income progressive taxes and the timing of charitable contributions using an econometric model of charitable giving and a 10 year panel of tax return data i find that previous studies have underestimated the effects of permanent income and overestimated the effects of permanent changes in tax prices the significant statutory tax changes that occurred during the 1980s especially in 1986 serve to identify the key model parameters my results imply that people smooth their giving when transitory income changes but also time their giving to exploit transitory changes in tax prices the results also raise questions about how effectively the tax incentives permanently influence the level rather than just the timing of charitable giving by individuals

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

global financial risk aggregate fluctuations and unemployment dynamics abstract we use a panel structural vector autoregression methodology to study the impact of global financial risk shocks in emerging market economies emes versus small open advanced economies soaes the short term responses of gdp investment and un employment are similar in emes compared to soaes but their medium term responses differ considerably in emes the shock propagates less across gdp and investment and the response of unemployment is prominently more subdued further analysis suggests that while in emes these dynamics can be traced back to the response of country interest rates to global financial risk shocks and to the average degree of firm informality in soaes these factors are not at play instead for soaes the dynamics of bank credit can matter to some degree but more broadly a global financial risk shock passes through more directly into the economy

the evolution of income concentration in japan 1886 2005 evidence from income tax statistics abstract this paper studies the evolution of income concentration in japan from 1886 to 2005 by constructing long run series of top income shares and top wage income shares using income tax statistics we find that i income concentration was extremely high throughout the pre wwii period during which the nation underwent rapid industrialization ii a drastic de concentration of income at the top took place in 1938 1945 iii income concentration remained low during the rest of the century but shows some sign of increase in the last decade and iv top income composition in japan has shifted dramatically from capital income to employment income over the course of the twentieth century we attribute the precipitous fall in income concentration during wwii primarily to the collapse of capital income due to wartime regulations and inflation we argue that the change in the institutional structure under the occupational reforms made the one time income de concentration difficult to reverse in contrast t

the effect of marginal tax rates on income a panel study of bracket creep this paper uses a panel of individual tax returns and the bracket creep as source of tax rate variation to construct instrumental variables estimates of the sensitivity of income to changes in tax rates from 1979 to 1981 the us income tax schedule was fixed in nominal terms while inflation was high around 10 this produced a real change in tax rate schedules taxpayers near the top end of a tax bracket were more likely to creep to a higher bracket and thus experience a rise in marginal rates the following year than the other taxpayers compensated elasticities can be estimated by comparing the differences in changes in income between taxpayers close to the top end of a tax bracket to the other taxpayers these estimates based on comparisons between very similar groups are robust to underlying changes in the income distribution such as a rise in inequality the elasticities of taxable income and adjusted gross income are around 0 4 and significant but the elasticities of wage income are in general insignificant and close to zero 2002 elsevier science b v all rights reserved

domestic credit growth and international capital flows during the pre crisis period europe experienced substantial cross country variation in domestic credit growth and cross border capital flows we investigate the inter relations between domestic credit growth and international capital flows during the period 1993 2008 with a special focus on the boom period of 2003 2008 we establish that domestic credit growth in european countries is strongly related to net debt inflows but not to net equity inflows this pattern also holds for an extended sample of 54 advanced and emerging economies

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

adjustment costs firm responses and micro vs macro labor supply elasticities evidence from danish tax records we show that the effects of taxes on labor supply are shaped by interactions between adjustment costs for workers and hours constraints set by firms we develop a model in which firms post job offers characterized by an hours requirement and workers pay search costs to find jobs we present evidence supporting three predictions of this model by analyzing bunching at kinks using danish tax records first larger kinks generate larger taxable income elasticities second kinks that apply to a larger group of workers generate larger elasticities third the distribution of job offers is tailored to match workers aggregate tax preferences in equilibrium our results suggest that macro elasticities may be substantially larger than the estimates obtained using standard microeconometric methods

the elasticity of taxable income during the 1990s new estimates and sensitivity analyses author affiliation seth h giertz sgiertz2 unl edu acknowledgment the author wishes to thank david weiner ed harris bob dennis doug hamilton tom woodward emmanuel saez chris bollinger and three anonymous referees for their comments and assistance 1 introductioneconomists have long recognized that taxation creates economic inefficiency by distorting relative prices often between leisure and all other goods in the economy even a broad based income tax can have substantial efficiency costs so long as leisure remains untaxed harberger 1964 uses this as motivation for comparing the efficiency implications of direct versus indirect taxation in so doing he shows how labor supply elasticities can be used to measure the efficiency implications of income taxation 1 harberger s analysis had a profound influence on public and labor economists spurring increased research into labor supply elasticities which were seen as proxies for the efficiency costs from taxation more than two decades after harberger economists began to emphasize the variety of other margins over which taxes can distort behavior in addition to hours worked these economists noted that these other behavioral responses may too have important implications for efficiency an important building block in the evolution of this literature was set forth by slemrod 1990 who presented a hierarchy of behavioral responses to taxation slemrod divided behavior into three categories based on their responsiveness to taxes his least responsive category real responses includes individuals changing consumption and work patterns and businesses altering investment and production decisions second in order of responsiveness is circumvention which includes both illegally evasion and legally avoidance bypassing the tax system 2 in the case of evasion income is concealed from tax authorities or factors that offset tax liabilities such as expenses and deductions are inflated beyond what is legally permitted in the case of avoidance income is shifted in order to receive more favorable tax treatment diverting income into a tax deferred retirement account is an example of avoidance 3 included in circumvention is the expenditure of time and money necessary to avoid or evade taxation third on the hierarchy and the most responsive is the timing of income receipt which includes pulling the receipt of income into the previous year or pushing it into the next in order to take advantage of more favorable tax treatment while not altering real behavior 4 slemrod further recognizes that the type of behavioral response could have implications for both tax revenue and tax incidence and in some cases efficiency predating slemrod s insights lindsey 1987 produced elasticity estimates for taxable income although what lindsey termed taxable income more closely approximates adjusted gross income agi instead of labor supply 5 lindsey s estimated elasticities were much larger than the labor supply literature would have suggested lindsey emphasized the revenue implications of the elasticity of taxable income eti but not its efficiency implications building on slemrod and lindsey feldstein 1995 produced eti estimates but went much further than lindsey in describing the behaviors that could affect taxable income he argued that many of these behaviors were not captured by labor supply elasticities furthermore feldstein posited that income taxation creates economic inefficiency not only by distorting the relative price between labor and leisure but more broadly by distorting the relative price between goods or activities that are taxed and those that are not taxed since leisure is not the only untaxed activity for example in response to taxes not only work hours but also work effort might change

recent evolutionary theorizing about economic change this famous passage from marshall s principles of economics it first appeared in the fifth edition which came out in 1907 nicely brings out two issues which are as germane to economics today as they were when marshall wrote the first is the heavy reliance by economists in their formal theorizing on the notion of equilibrium the other is the appeal that biological conceptions3x201d have for many economists particularly when their focus is on economic change

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

saving the euro mitigating financial or trade spillovers this paper analyzes through what channels the euro crisis affected firms and the efficacy of policies to mitigate the crisis it analyzes stock price responses for 3 045 nonfinancial firms in 16 countries to four key policy events during 2010 11 using precrisis benchmarks it separates financial effects from trade effects and examines how bank and trade linkages propagated shocks it finds that policy measures affected financially dependent firms more particularly in creditor countries with greater bank exposure to peripheral euro countries in statistically and economically significant ways trade linkages with peripheral countries played little role although euro movements meant some differential effects

the elasticity of taxable income evidence and implications abstract a central tax policy parameter that has recently received much attention but about which there is substantial uncertainty is the overall elasticity of taxable income we provide new estimates of this elasticity which address identification problems with previous work by exploiting a long panel of tax returns to study a series of tax reforms throughout the 1980s this identification strategy also allows us to provide new evidence on both the income effects of tax changes on taxable income and on variation in the elasticity of taxable income by income group we find that the overall elasticity of taxable income is approximately 0 4 the elasticity of real income not including tax preferences is much lower we estimate small income effects of tax changes on reported income implying that the compensated and uncompensated elasticities of taxable income are very similar we estimate that this overall elasticity is primarily due to a very elastic response of taxable income for taxpayers who have incomes above 100 000 per year who have an elasticity of 0 57 while for those with incomes below 100 000 per year the elasticity is less than one third as large moreover high income taxpayers who itemize are particularly responsive to taxation our estimates suggest that optimal tax structures may feature tightly targeted transfers to lower income taxpayers and a flat or even declining marginal rate structure for middle and high income taxpayers
