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

convergence to the law of one price without trade barriers or currency fluctuations using a panel of 51 prices from 48 cities in the united states we provide an upper bound estimate of the rate of convergence to purchasing power parity we find convergence rates substantially higher than typically found in cross country data we investigate some potentially serious biases induced by i i d measurement errors in the data and find our estimates to be robust to these potential biases we also present evidence that convergence occurs faster for larger price differences finally we find that rates of convergence are slower for cities farther apart however our estimates suggest that distance alone can only account for a small portion of the much slower convergence rates across national borders

on measures of excess burden and their application abstract new measures of the additional excess burden of a tax reform are proposed and are shown to be useful in three key policy applications these new measures induce a unique measure of marginal excess burden meb among its interesting properties meb is uniformly zero for a proportional tax on inelastically supplied labor problems in applying the standard measures of total excess burden are demonstrated it is concluded that the induced measure of the marginal cost of funds mcf should be regarded as the most useful concept in applied tax analysis

smuggling camouflaging and market structure we examine how market structure and enforcement affect smuggling and welfare in a model where smuggling is camouflaged by legal sales conditions are given for when some but not necessarily all firms smuggle with camouflaging the market price is below the price when all sales are legal so smuggling improves welfare if the price effect outweighs excess smuggling cost this welfare effect is directly related to the degree of competition increased enforcement in this model potentially reduces welfare the model is shown to be consistent with evidence on cigarette smuggling in the united states for 1975 1982

retirement in dual career families a structural model a structural econometric model of retirement of dual career couples is specified and estimated with panel data from the national longitudinal survey of mature women a coincidence of spouses retiring together despite the younger ages of wives suggests explicit efforts at coordination the estimates suggest that one reason is a correlation of tastes for leisure more important each spouse and perhaps husbands in particular values retirement more once their spouse has retired the opportunity set accounts for peaks in the retirement hazards of each spouse individually but not for peaks in the simultaneous retirement of both spouses

taxpayer responses in good times and bad abstract i show that the magnitude of taxpayer responsiveness a key parameter in public finance varies through time using linked administrative data and identifying responses from changes in notches i document a marked decline in responsiveness during the great recession that cannot be explained by increased enforcement i characterize which employee employer pairs are best at reporting tax advantaged incomes workers in industries with above average responsiveness such as construction were disproportionately affected by the recession i show responsiveness also declined for workers who remained matched with the same employers throughout the period

earnings inequality and mobility in the united states evidence from social security data since 1937 this paper uses social security administration longitudinal earnings micro data since 1937 to analyze the evolution of inequality and mobility in the united states annual earnings inequality is u shaped decreasing sharply up to 1953 and increasing steadily afterward short term earnings mobility measures are stable over the full period except for a temporary surge during world war ii virtually all of the increase in the variance in annual log earnings since 1970 is due to increase in the variance of permanent earnings as opposed to transitory earnings mobility at the top of the earnings distribution is stable and has not mitigated the dramatic increase in annual earnings concentration since the 1970s long term mobility among all workers has increased since the 1950s but has slightly declined among men the decrease in the gender earnings gap and the resulting substantial increase in upward mobility over a lifetime for women are the driving force behind the increase in long term mobility among all workers

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

labor income responds differently to income tax and payroll tax reforms we estimate the responses of gross labor income with respect to marginal and average net of tax rates in france over the period 2003 2006 we exploit a series of reforms to the income tax and payroll tax schedules affecting individuals who earn less than twice the minimum wage our estimate for the elasticity of gross labor income with respect to the marginal net of income tax rate is around 0 2 while we find no response to the marginal net of payroll tax rate the elasticity with respect to the average net of tax rate is not significant for the income tax schedule while it is close to 1 for the payroll tax schedule a plausible explanation is the existence of significant labor supply responses to the income tax schedule combined with sticky posted wages i e the gross labor income minus payroll taxes divided by hours worked finally the effect of the net of income tax rate seems to be driven by participation decisions in particular those of married women

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

unemployment and income distribution time series evidence from sweden for a long time swedish politicians have been devoted to keeping unemployment at low levels the main reason for this devotion is probably the belief that higher unemployment increases inequality of income and welfare this is a reasonable belief since unemployment risks are highest among people with low earnings capacity even when they have a job by means of micro data it is easy to verify a marked low income profile of unemployment further the swedish unemployment insurance system replaces only about 70 per cent of foregone income and quite many unemployed do not qualify for any benefits see bjorklund and holmlund 1991 increases in unemployment however are associated with many changes in the economy with complex consequences for the personal distribution of income in addition to the income losses suffered by those who become unemployed higher unemployment also affects the factor shares of income the profit share typically declines during recessions and because upper income groups receive a relatively high proportion of their income from capital income a countervailing mechanism is involved changes in unemployment also affect inflation which in turn might influence the personal distribution of income the distributional effects of inflation are an open question this note makes an investigation into the relationship between unemployment and the personal distribution of income using swedish time series data the method was first used on u s data by blinder and

demand and distance evidence on cross border shopping while many studies have documented deviations from the law of one price in international settings evidence is scarce on the extent to which consumers take advantage of price differentials and engage in cross border shopping we use data from 287 swedish municipalities to estimate how responsive alcohol sales are to foreign prices and relate the sensitivity to the location s distance to the border typical results suggest that the elasticity with respect to the foreign price is around 0 4 in the border region moving 200 400 kilometers inland reduces it to 0 2 0 1 given that cross country price differences for alcohol and other products are often caused by taxes our evidence has implications for the debate on tax competition harmonization

the impact of marginal tax rates on taxable income evidence from state income tax differentials the relationship between marginal tax rates and taxable income is analyzed with a large cross section of income tax returns filed by individuals who face different marginal tax rates because of state income tax differentials the empirical results suggest that an increase in the marginal tax rate reduces taxable income primarily because taxpayers claim larger deductions high income taxpayers are found to be more responsive to tax rate changes than lower income individuals the findings are compared to those of other recent studies incorporating a wider range of taxpayer responses to tax rate changes than considered in this study

the effect of taxes on male and female labor supply in sweden this paper estimates labor supply functions for married men and women in sweden using data from 1980 taking account of the complete form of individuals budget constraints both linear and quadratic supply functions are estimated with and without random preferences a novel feature is that for women the wage rate and labor supply functions are estimated simultaneously using a full information maximum likelihood method this method yields substantially larger wage and income elasticities than does the previously used two step methods another result is that the quadratic supply function wage elasticities for men and women are virtually the same if the elasticities are evaluated at the same net wage rate and hours of work for men and women the estimated functions are used to calculate the effect of tax reforms

a patchwork safety net a survey of cliometric studies of income maintenance programs in the united states in the first half of the twentieth century social welfare programs in the usa are designed to serve as safety nets for people in hard times in contrast with the universal approach found in many other developed western nations in a survey of cliometric studies of social welfare programs in the usa we examine the variation in the safety net in the usa across states in the 20th century the determinants of the variation and its impact on socioeconomic outcomes the usa has always displayed substantial variation in the extent of the safety net because the features of most public social welfare programs have been and currently are determined by local and state governments even after the federal government became involved in the 1930s differences across states persist strongly for typically a decade although the persistence weakens with time and there are some periods when federal intervention led to a re ordering the rankings of state benefits differ from program to program and economic and political factors have different weights in determining benefit levels in panel data estimation of their effects variation in benefits across programs during the early 1900s had significant impact on labour markets economic activity family formation death rates and crime copyright 2010 blackwell publishing ltd

fuel tourism in border regions the case of switzerland this paper explores the issue of fuel tourism in switzerland for the period 1985 1997 a panel data model for the border regions of switzerland italy france and germany is estimated the results show a significant impact of the gasoline price differential on demand suggesting that a decrease of 10 in the swiss gasoline price leads to an increase in demand in the border areas of nearly 17 5 it is shown that fuel tourism accounted for about 9 of overall gasoline sales in the three regions during the period 1985 1997 and that the recently proposed swiss co2 tax might given current conditions eliminate net fuel tourism

trends in the transitory variance of earnings in the united states we decompose the rise in cross sectional variance of male annual earnings in the united states from 1969 to 1996 into permanent and transitory components we find that the variance of permanent earnings began rising in the the late 1970s and has continued to rise in the 1980s the variance of transitory earnings also rose in the 1980s but declined in the 1990s there are lags in the earnings process which require a structural model to pinpoint the exact calendar times at which the changes in trends occurred

do husbands and wives pool their resources evidence from the united kingdom child benefit common preference models of family behavior imply income pooling a restriction on family demand functions such that only the sum of husband s income and wife s income affects the allocation of goods and time testing the pooling hypothesis is difficult because most family income sources are not exogenous to the allocations being analyzed in this paper we present an alternative test based on a natural experiment a policy change in the united kingdom that transferred a substantial child allowance to wives in the late 1970s using family expenditure survey data we find strong evidence that a shift toward greater expenditures on women s clothing and children s clothing relative to men s clothing coincided with this income redistribution

labor supply and optimization frictions evidence from the danish student labor market abstract using danish administrative data i investigate the magnitude and nature of optimization frictions in the labor market of danish students danish students face a unique institutional setting that makes it possible to distinguish between different types of frictions and estimate their effect on individual utility i find that frictions significantly affect observed labor market outcomes in particular the empirical evidence points to inattention as the dominant type of friction in contrast my findings appear inconsistent with real adjustment costs price misperception and gradual learning overall optimization frictions reduce the utility of individuals by approximately 2 3 of disposable income

on the taxation of trade within and between households abstract tax reform proposals affect individual welfares in ways which strongly depend on the nature of specialisation in household production and the pattern of trade within households variation in the degree of specialisation in domestic production across households strongly influences the impacts on individual tax burdens of a given tax reform the standard models of the economics literature cannot be used to analyse these issues because they ignore the two person nature of households and the existence of household production and trade this paper proposes a simple and tractable model to remedy this and uses it to analyse the impacts of the types of tax reform that have been the subject of recent policy debate

the effects of the unemployment insurance payroll tax on wages employment claims and denials abstract following a 13 year period when all employers in washington paid the same unemployment insurance ui tax rate washington was forced to adopt an experience rated tax system in 1985 we use this natural experiment to explore both tax incidence and the effects of experience rating we find that industry average tax rates are largely passed on to workers through lower earnings however our estimates imply that a firm can shift much less of the difference between its tax rate and the industry average rate our results also indicate that experience rating reduces turnover and ui claims and increases claim denials

identifying the elasticity of taxable income we use matched panels from the current population survey along with a grouping instrumental variables estimator to provide new estimates of the elasticity of taxable income our identification strategy exploits the fact that federal and state tax reforms over the past three decades have differentially affected cohorts across states and over time we find that the elasticity is in the range of 0 4 0 55 the implication of our new estimates for tax policy is that the revenue maximising tax rate is nearly 30 percentage points lower than that obtained when we use the typical identification strategy in the literature

international trade without ces estimating translog gravity this paper derives a micro founded gravity equation in general equilibrium based on a translog demand system that allows for endogenous markups and substitution patterns across goods in contrast to standard ces based gravity equations trade is more sensitive to trade costs if the exporting country only provides a small share of the destination country s imports as a result trade costs have a heterogeneous impact across country pairs with some trade flows predicted to be zero i test the translog gravity equation and find strong empirical support in its favor

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

failure is an option institutional change entrepreneurial risk and new firm growth does an institutional change that lowers failure barriers improve new firm growth we take advantage of a quasi natural experiment in japan that drastically reduced the stringency of bankruptcy regulations to examine this question using longitudinal data over a 10 year period we find that bankruptcy reform increases the rates of bankruptcy and founding and more importantly the likelihood of high growth ventures by disproportionately encouraging elite individuals i e those with superior human and social capital to start firms in turn these firms are more likely than others to achieve high growth broadly put we contribute to research at the nexus of institutional theory and entrepreneurship by emphasizing the connectedness of barriers to failure venture growth and elite entrepreneurs we also highlight how institutional change that eases bankruptcy change can foster a regenerative cycle of failure founding and growth by attracting more capable entrepreneurs overall we conclude that lowerin

capital gains taxation and realizations evidence from interstate comparisons this paper documents the interstate variation in capital gains taxation and examines the relation between the marginal tax rate on capital gains and aggregated state level realizations between 1979 and 1990 using state level aggregated data rather than data on individual taxpayers alleviates the problem that the marginal tax rate is endogenous to the amount of capital gains realized the estimated elasticity of realizations with respect to the tax rate is 0 65 smaller than that found by most researchers using panel data this finding is robust to a variety of alternative specifications copyright 1995 by mit press

an economic model of welfare stigma perhaps the most basic assumption of the economic theory of consumer demand is that more is better than less virtually all of the major propositions of consumer theory can in a certain sense be derived from the assumption that goods are good interestingly however this tenet seems to be violated by the behavior of many individuals in the low income population for many turn out to be eligible for a positive welfare benefit but do not in fact join the welfare rolls for example it has been estimated that in 1970 only about 69 percent of the families eligible for afdc aid to families with dependent children participated in the program see richard michel 1980 the corresponding percentage for afdc u the program for which families with an unemployed male are eligible was only 43 percent and the participation rate in the food stamp program was only 38 percent see maurice mcdonald 1977 this phenomenon has puzzled many investigators because such individuals do not locate on the boundaries of their budget sets consequently most investigators ignore the problem when studying the effects of welfare programs on behavior in this paper this seemingly irrational rejection of an increase in income is modeled as resulting from welfare stigma that is from disutility arising from participation in a welfare program per se 1 the existence of stigma has been amply documented in the sociological literature patrick horan and patricia austin 1974 lee rainwater 1979 where interviews of recipients have often uncovered feelings of lack of self respect and negative self characterizations from participation in welfare nevertheless this phenomenon has not been modeled and many questions consequently remain when is the disutility of participation strong enough to prevent participation shouldn t we expect individuals to weigh the disutility of participation against the potential benefit in their decisions what is the elasticity of participation with respect to the potential benefit also in a slightly different vein how are the work disincentives of welfare affected by stigma these questions have been given scant attention by economists yet they are crucial for our ability to predict the impact of various welfare programs on the lowincome population here these questions are addressed by modeling nonparticipation as a utility maximizing decision the model is developed and estimated for the afdc program 2 the model posits an individual utility function containing not just disposable income but

the american welfare system and family structure an historical perspective cross sectional studies find a positive relationship between a state s welfare benefits and single motherhood but is this evidence of a welfare effect or rather of cross state differences in social attitudes that influence both policy and behavior this paper demonstrates that the spatial variation in welfare policy long preceded the spatial correlation of policy and behavior undermining the social norm hypothesis but the findings also raise doubts about the role that welfare policy played in the changes in family structure over the century the correlation between welfare benefits and family structure only appears in 1970 and then only for whites

assistance to the poor in a federal system abstract this paper explores the roles of different levels of government in assisting the poor using a model incorporating utility interdependence the paper first presents some theoretical results indicating how levels of poor relief vary with the extent of mobility of the poor under both centralized and decentralized systems of support it then provides a survey of the empirical work on migration of the poor along with a brief historical discussion of the experience under the english poor laws the concluding section turns to normative issues and contends that mobility of the poor is a basic source of inefficiency in wholly decentralized systems of support this inefficiency along with certain other equity considerations establishes a role for the central government in assistance to the poor

tax reform and collective family decision making abstract traditional analysis of tax reform treats market behaviour as arising out of individual utility maximisation in this paper behaviour is modelled as the pareto efficient outcome of a family decision process conditions for the existence of a feasible pareto improving tax change are presented and contrasted with those that obtain in the individualistic case the consequences of treating households as a single individual are also discussed

elasticity of taxable income evidence from changes in municipal income tax rates in finland the elasticity of taxable income eti is a key parameter in income tax analysis both in terms of efficiency and tax revenue this paper uses finnish data to analyze the eti i use changes in flat municipal income tax rates as an instrument for overall changes in marginal tax rates this instrument is not a function of individual income and thus the eti estimates are less susceptible to bias caused by differential trends across the income distribution in general instruments used in previous studies do not have this feature my preferred estimate for the average eti is 0 21 this article is protected by copyright all rights reserved

federalizing benefits the introduction of supplemental security income and the size of the safety net abstract in 1974 supplemental security income ssi federalized cash welfare programs for the elderly blind and individuals with disabilities imposing a national minimum benefit and differentially raising payment levels in states that paid below its benefit floor we show that this increased disability participation but shrank non disability cash transfer programs for every four new ssi recipients three came from other welfare programs each dollar of per capita ssi income increased total per capita transfer income by just over 50 cents federalizing part of a patchwork safety net need not increase redistribution by as much as traditional models of fiscal federalism suggest

are changes of organizational form costly income shifting and business entry responses to taxes abstract drawing on administrative panel data covering the full population of business owners in the uk i study the effects of differential tax liabilities across organizational forms on business entry and on income shifting i find that a 10 increase in savings from incorporation leads to a 1 7 increase in the number of new business owners however higher entrepreneurial entry is offset by income shifting increasing the hazard rate of incorporation of the existing self employed by up to 2 3 for a 10 increase in tax savings i show that despite large tax savings from incorporation exceeding 10 pp in some years a substantial proportion of business owners fail to incorporate suggesting that income shifting through incorporation is not the primary avoidance channel for the self employed

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

assessing tax reforms through the elasticity of reported income an empirical analysis for spain this paper demonstrates the usefulness of the elasticity of reported income to assess tax reforms from the perspectives of tax revenue and well being employing different identification strategies

taxation and the earnings of husbands and wives evidence from sweden i examine the response of husbands and wives earnings to a tax reform in which husbands and wives tax rates changed independently allowing me to examine the effect of both spouses incentives on each spouse s behavior i analyze the large swedish tax reform of 1990 1991 and find that in response to a compensated fall in one spouse s tax rate each spouse s earnings rise i compare these results to those of simplified econometric models used in the typical setting in which independent variation in each spouse s tax rate is unavailable i find that standard econometric specifications may produce substantially biased estimates

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

the impact of fuel tourism on retailers diesel price in spanish neighbouring regions since 1986 car fuel consumption in spain has been subject to the special hydrocarbons tax and the value added tax in addition since 2002 regional governments have been able to apply a regional excise duty on hydrocarbons this article analyses the impact that such a regional tax has on the retailer s diesel price at the border of the province of lugo in the region of galicia and the province of leon in the region of castile leon only the former region has the regional tax evidence shows that variations in the price of diesel at the border of lugo are of the same sign but of lower intensity than at the border of leon the price price elasticity is 0 8060 these results suggest that service stations located in regions with higher excise duties use their price policy to lessen the negative effects generated for fuel tourism

what causes public assistance caseloads to grow this paper uses state panel data to investigate changes in public assistance caseloads through the end of the afdc program in 1996 with particular attention to the rapid increase in caseloads between 1990 and 1994 previous research has focused on total caseloads with attention to economic and policy variables and does a relatively poor job of explaining this caseload increase this paper utilizes a much richer set of control variables to investigate the causes of caseload change it separates afdc caseloads into three subcomponent programs separately investigating changes within the afdc up program afdc child only cases and the remaining core afdc cases with benefits paid to single mothers and their children and it explores whether this caseload rise was driven by changes in takeup rates versus in eligibility the results indicate a large unexplained rise in total afdc caseloads even with a very rich specification a good share of this is due to sharp increases in child only cases driven by program and demographic shifts to a lesser extent this rise was caused by the expansion of afdc up to all states these two factors explain half of the overall rise and all of the unexplained rise in afdc caseloads the remaining increase in core afdc cases benefits received by single mothers and their children is well explained within the model and is the result of economic demographic political and policy changes these variables appear to have increased eligibility among the core afdc population in the early 1990s during the economic slowdown takeup rates also increased during this time period but not by a large amount

cross border commuting and consuming an empirical investigation abstractthis article contributes to our understanding of cross border activity in general and the determinants of cross border trade in particular by focusing on the part of cross border sales that arise due to work related cross border crossings of households we analyse empirically how cross border consumption expenditures vary across product and services categories as well as household characteristics using representative household survey data of cross border commuters to luxembourg in total these households spend an estimated 17 of their gross annual income across the border contributing about 10 to the total household final consumption expenditure hfce in luxembourg cross border expenditure is linked to individual and household related characteristics and to distance between home and work cross border commuters systematically exploit arbitrage opportunities that arise because of existing price level index differences between the country of work and the country of residence

collective labor supply and welfare the paper develops a general collective model of household labor supply in which agents are characterized by their own possibly altruistic preferences and household decisions are only assumed to be pareto efficient an alternative interpretation is that there are two stages in the internal decision process agents first share nonlabor income according to some given sharing rule then each one optimally chooses his or her own labor supply and consumption this setting is shown to generate testable restrictions on labor supplies moreover the observation of labor supply behavior is sufficient for recovering individual preferences and the sharing rule up to a constant finally the traditional tools of welfare analysis can be adapted to the new setting

a simple model of commodity taxation and cross border shopping this paper sets up a simple model in which two countries differing in geographical extent engage in commodity tax competition originating in opportunities for cross border shopping the non cooperative tax equilibrium and various coordination initiatives are examined in the benchmark model and in two model extensions incorporating i costs of transportation for goods and ii border inspection among the more surprising results are the following with i pure profits accrue to sellers near the border but subjecting them to tax may lower the country s total tax revenue with ii the volume of cross border shopping may well increase jel classification h20 h87 h26

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

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

more giving or more givers the effects of tax incentives on charitable donations in the uk abstract this paper estimates the effects of tax incentives on charitable contributions in the uk using the universe of self assessment income tax returns between 2005 and 2013 we exploit variation from a large reform in 2010 to estimate intensive and extensive margin tax price elasticities of giving using a predicted tax rate instrument for the price of giving relative to consumption we find an intensive margin elasticity of about 0 2 and an extensive margin elasticity of 0 1 yielding a total elasticity of about 0 3 to further explore the extensive margin response we propose a model with a fixed cost of declaring donations and obtain a structural estimate of that cost of around 47 we also study the welfare effects of tax incentives extending the theoretical literature to allow for extensive margin giving and for a fixed cost of declaring donations taking into account these factors there is a case for increasing the subsidy on charitable giving in the uk

collective household labor supply nonparticipation and income taxation in this paper we adopt the usual assumptions of the collective approach i e individualism and efficiency to study household labor supply the theoretical innovation is 2 fold first we incorporate the decision to participate in the labor market in the initial setting second we abandon the assumption of linearity of the budget constraint we show that i structural elements such as preferences or the outcome of the decision process can be recovered and ii testable restrictions are generated from the observation of the household labor supplies we also examine for this model how to simulate the incidence of fiscal reforms

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

do tax credits stimulate r d spending the effect of the r d tax credit in its first decade abstract this paper examines the impact of the u s federal r d tax credit between 1981 1991 using confidential irs data from corporate tax returns the empirical analysis makes two key advances on previous work first it implements a new instrumental variables iv strategy based on tax changes that directly addresses the simultaneity of r d spending and marginal credit rates second the analysis makes use of new restricted access irs corporate return data describing r d expenditures estimates imply that a10 reduction in the user cost of r d leads the average firm to increase its research intensity the ratio of r d spending to sales by 19 8 in the short run long run estimates imply that the average firm faces adjustment costs and increases spending over time though small and young firms show evidence of reversing initial increases analysis of the components of qualified research shows that wages and supplies account for the bulk of the increase in research spending elasticities of qualified and total research intensities from a smaller sample suggest firms respond to user cost changes largely by increasing their qualified spending meaning that the type of r d the federal credit deems qualified research is an important margin on which the credit affects firm behavior

how far for a buck tax differences and the location of retail gasoline activity in southeast chicagoland abstract we exploit variation in gasoline and cigarettes taxes in adjacent political jurisdictions for northern illinois and indiana to examine consumers trade off between prices and travel we develop a model that relates activity in the retail gasoline industry around the tax borders to consumer locations our results indicate that the willingness of a typical chicagoland consumer to travel an additional mile to buy gasoline corresponds to about 0 065 to 0 084 per gallon according to our estimates the observed area of chicago the jurisdiction with the highest taxes is missing approximately 40 of the capacity that would exist were taxes equalized

35 years of reforms a panel analysis of the incidence of and employee and employer responses to social security contributions in the uk we exploit variation in national insurance contributions nics the uk s system of social security contributions and a large panel dataset to examine the effects of 35 years of employee and employer nics reforms on labour cost gross earnings plus employer nics hours of work and labour cost per hour both immediately 0 6 months after reforms are implemented and in the slightly longer term 12 18 months we consider assumptions under which the estimated coefficients on net of marginal and net of average tax rates in a panel regression can be interpreted as behavioural elasticities or as reflecting incidence we find a compensated elasticity of taxable earnings with respect to the marginal rate of employee nics of about 0 2 0 3 operating largely through hours of work while that with respect to the marginal rate of employer nics is not statistically significantly different from zero we also find that labour cost falls by a much larger amount when the average rate of employer nics is reduced than when the average rate of employee nics is reduced which is consistent with the economic incidence of nics being strongly affected by its formal legal incidence estimates from the hours and hourly labour cost regressions provide further support to this interpretation of the findings and also suggest the presence of substantial income effects though also after 1999 a puzzling effect of average employer nics rates on hours of work each of these results remains true after 12 18 months if anything coefficients on lagged changes in nics rates strengthen these findings implying that any shifting of employer nics changes to the individual employees concerned and vice versa for employee nics does not begin over this time horizon these results are similar to those found by lehmann et al 2013 for france but represent an extension of that work by considering hours as well as labour cost responses and second year as well as immediate effects

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

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

business owners and income shifting evidence from finland this study examines income shifting between tax bases among the owners of privately held businesses the dual income tax system in finland offers noticeable incentives for income shifting between wages and dividends for business owners the dividend tax reform of 2005 enables us to study how this particular form of tax avoidance reacts to an exogenous change in tax rates our results support highly active income shifting behavior we find that the income shifting effect is homogeneous across different owners and firms however we find that the size of the tax incentive affects the size of the response suggesting that costs related to income shifting are important

the tax effect on taxable income from privately held businesses the implications of the tax elasticity of taxable income have been widely discussed in the literature this study uses the reported rate of return to capture the effects of tax changes on taxable income from privately held businesses households decisions concerning reporting rates of return are embedded in a selection model of business investment decisions with 1983 1989 survey of consumer finances panel data the tax elasticity of the reported rates of return on privately held businesses is found to be positive and large the tax elasticity of taxable income from privately held businesses is thus crucial for policy evaluation several reasons for the high tax elasticity and the implications of it are also discussed

corporate tax incentives and capital structure new evidence from uk firm level tax returns abstract we investigate how companies capital structure is affected by corporate income taxes using confidential company level tax returns for a large sample of uk firms exploiting variation in companies marginal tax rates we find a positive and substantial long run tax effect on leverage leverage responds more to decreases in the marginal tax rate and it responds to changes in the marginal rather than the average tax rate most importantly we find that the marginal tax rate based on tax returns has greater explanatory power for companies leverage than the marginal tax rate based on financial statements our study suggests that errors in the measurement for tax incentives using financial statements could lead to underestimation of the tax effects on capital structure

estimating taxable income responses with elasticity heterogeneity abstract we explore elasticity heterogeneity in the estimation of the elasticity of taxable income eti and propose potentially valid instruments we show that previously used instruments are not valid and yield weighted averages of etis of different taxpayers plus a bias using the nber tax panel for 1979 1990 we find a weighted average eti of 0 57 when using all available variation in budget set changes provided by the tax reforms in the data our results also demonstrate that elasticity heterogeneity is an important explanation for the remarkable divergence of estimates in the previous literature

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

changes in relative wages and family labor supply the large changes in relative wages that occurred during the 1980s provide fertile ground for studying the behavioral responses of married couples to the wage changes of husbands and wives i find estimates of own wage and cross wage elasticities for men that are very small the own wage elasticity for women is positive and the cross wage elasticity for women suggests a strong negative response of female labor supply to changes in their husband s wages family labor supply behavior determines how changes in individual wage rates translate into family earnings changes the responses of women to changes in their husband s wages attenuated somewhat the increases in individual wage inequality at the family level the results suggest that the earnings of the wives of low income men would actually have fallen over the decade if women s labor supply did not respond to changes in their husbands wages however assortative mating implies that wage changes of husbands and wives are correlated and so family earnings inequality still grew during the decade of the 1980s

afdc ssi and welfare reform aggressiveness caseload reductions versus caseload shifting welfare reform has made receipt of cash benefits more difficult and less attractive for single mothers we examine whether reforms of afdc affected caseloads of another program supplemental security income ssi we exploit state variation in welfare reform over time and find that female headed households in states aggressively pursuing welfare reform were 21 6 percent more likely to receive ssi this implies that a decrease in caseloads in one program cannot be interpreted as an equal sized decrease in the number of families receiving public assistance in addition our results have policy implications for the well being of families affected by welfare reform time limits

prices taxes and automotive fuel cross border shopping abstract the aim of the present paper is to determine whether differences in automotive fuel prices among neighboring autonomous communities i e spanish political administrative regions affect the decisions taken by individuals regarding the region in which to purchase fuel in particular the intention is to discover if price increases in certain autonomous communities as a result of the application of the regional tranche of the hydrocarbon retail sales tax hrst has affected fuel purchases in neighboring communities in order to achieve the above mentioned objectives the monthly purchases of automotive diesel in aragon between january 2001 and march 2007 is estimated from the fuel price in aragon the relation between prices in each of the bordering communities and aragon weighted by density of traffic the number of vehicles registered in that community and three dummy variables representative of the implementation of the regional tranche of the hrst in madrid catalonia and valencia the paper finds empirical evidence to demonstrate a positive effect of the relative prices in the neighboring communities and vehicle registrations and also a negative effect of prices in aragon upon the acquisition of diesel in this region in the case of catalonia some evidence suggests that the price effect may have been strengthened following the introduction of the regional tranche of the hrst in august 2004

inside the war on poverty the impact of food stamps on birth outcomes this paper evaluates the health impacts of a signature initiative of the war on poverty the introduction of the modern food stamp pro gram fsp using variation in the month fsp began operating in each u s county we find that pregnancies exposed to fsp three months prior to birth yielded deliveries with increased birth weight with the largest gains at the lowest birth weights we also find small but statistically insig nificant improvements in neonatal mortality we conclude that the sizable increase in income from fsp improved birth outcomes for both whites and african americans with larger impacts for african american mothers n this paper we evaluate the health consequences of a sizable improvement in the resources available to ameri ca s poorest in particular we examine the impact of the food stamp program fsp which in 2007 provided 34 billion in payments to about 13 million households on infant health our paper makes two distinct contributions first although the goal of the fsp is to increase the nutri tion of the poor few papers have examined its impact on health outcomes second building on work by hoynes and schanzenbach 2009 we argue that the fsp treatment represents an exogenous increase in income for the poor our analysis therefore represents a causal estimate of the impact of income on health an important topic with little convincing evidence due to concerns about endogeneity and reverse causality currie 2009 we use the natural experiment afforded by the nation wide rollout of the modern fsp during the 1960s and early 1970s our identification strategy uses the sharp timing of the county by county rollout of the fsp which was initially constrained by congressional funding authorizations and ultimately became available in all counties by 1975 speci fically we use information on the month the fsp began operating in each of the roughly 3 100 u s counties and examine the impact of the fsp rollout on mean birth weight low birth weight gestation and neonatal mortality throughout the history of the fsp the program para meters have been set by the u s department of agriculture usda and are uniform across states in the absence of the state level variation often leveraged by economists to eval uate transfer programs previous fsp research has typically resorted to strong assumptions as to the comparability of fsp participants and eligible nonparticipants currie 2003 not surprisingly the literature is far from settled as to what casual impact if any the fsp has on nutrition and health hoynes and schanzenbach 2009 use this county rollout to examine the impact of the fsp on food consumption using the psid they found that the introduction of the fsp increased total food spending and decreased out of pocket food spending importantly consistent with the predictions of canonical microeconomic theory the magnitude of the increase in food expenditures was similar to an equivalent sized income transfer implying that most recipient house holds were inframarginal that is they would spend more on the subsidized good than the face value of the in kind transfer as one of the largest antipoverty programs in the united states comparable in cost to the earned income tax credit eitc and substantially larger than temporary assistance to needy families tanf understanding fsp effects is valuable both in its own right and for what it reveals about the relationship between income and health 1

jeux sans frontieres tax competition and tax coordination when countries differ in size closer international integration is putting increasing pressure on existing national tax structures this paper uses a simple two country model to address a range of consequent policy concerns focusing particularly on the role of country size differences in size exacerbate the inefficiency from noncooperative behavior harming both countries the smaller country loses from harmonization to any tax rate between those set in the noncooperative equilibrium but both countries gain from the imposition of a minimum tax anywhere in that range the fully optimal response to freer cross border trade however may be to do nothing jel h20 h77

the elasticity of taxable income in the presence of deduction possibilities several recent studies show that the elasticity of taxable income eti is not a sufficient statistic for the welfare costs of taxation due to factors such as tax base shifting this paper provides an additional argument demonstrating the non sufficiency of the eti namely tax deductions building on a theoretical framework which incorporates deductions in a standard optimal tax model we show that the eti is not sufficient for welfare analysis if i deductions generate externalities and if ii deductions are responsive to tax rate changes while the first condition should arguably hold true for the majority of tax deductions we provide an empirical examination of the second condition relying on rich german panel data from administrative tax records we exploit several tax reforms that were implemented in germany between 2001 and 2008 our main estimates indicate an overall eti between 0 54 and 0 68 and an elasticity of deductions with respect to the net of tax rate of about 0 9 these results suggest that the eti is not sufficient to calculate the welfare cost of taxation

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

welfare reform and the race to the bottom theory and evidence economists have argued that welfare migration leads to a race to the bottom in the choice of welfare benefits although a system of federal matching grants can remedy this problem the recent welfare reform law replaced the existing matching grant structure with block grants a policy change that appears undesirable to judge whether this critique of welfare reform is justified this paper evaluates the evidence in favor of a race to the bottom after explaining the theoretical effects of welfare migration the paper surveys the empirical evidence on the occurrence of such migration concluding that the evidence is mixed the discussion also considers recent empirical tests for strategic interaction which show that benefit levels in nearby states affect a given state s benefit choice the most plausible source of such interaction is a concern about welfare migration which leads policymakers to look at benefits in neighboring states when making their own choices judging that the evidence appears consistent with the existence of a race to the bottom the paper concludes that the demise of matching grants may be undesirable from a policy perspective
