equilibrium search models and the transition from school to work this paper applies the burdett mortensen 1998 equilibrium search model to study the school to work transitions of u s high school graduates we consider the case of discrete firm heterogeneity and provide a computational method to obtain the mle our results show that unemployed blacks receive fewer offers than whites and employed blacks are more likely to lose their jobs importantly employed blacks and whites receive job offers at the same rate assigning the whites search parameters to the blacks and re solving reveals that 75 percent of the observed wage differential is explained by the job destruction rate differences

reconciling the old and new census bureau education questions recommendations for researchers beginning with the 1990 census and the january 1992 current population survey cps the bureau of the census changed the emphasis of its educational attainment question from years of education to degree receipt using a matched sample from the 1991 and 1992 march cps this article addresses how to reconcile the old and new questions the effects of those methods on the estimated return s to education are then examined both the estimated linear return and the estimated college high school wage differential are slightly larger using information from the new question

corporate taxation and capital accumulation evidence from sectoral panel data for 14 oecd countries abstract we present new empirical evidence that sector level capital output ratios are strongly influenced by corporate tax incentives as summarised by the tax component of a standard user cost of capital measure we use sectoral panel data for the usa japan australia and eleven eu countries over the period 1982 2007 our panel combines internationally consistent data on capital stocks value added and relative prices from the eu klems database with corporate tax measures from the oxford university centre for business taxation our results for equipment investment are particularly robust and strikingly consistent with the basic economic theory of corporate investment

occupational self selection a human capital approach to sex differences in occupational structure a rich and diverse literature exists concerning the distribution of labor incomes one approach namely that of human capital concentrates on lifetime accumulation paths of earnings capacity units human capital individual variations in human capital imply differences in earnings power thereby yielding strong implications concerning earnings distribution within a population despite its explanatory power the human capital model has been widely criticized one criticism centers on its inability to obtain inferences concerning occupational distribution the purpose of this paper is to alleviate at least some such criticism by applying the hedonic price approach so as to embed occupational choice into the human capital framework the significance is that neoclassical economic theory can be used to obtain implications concerning the determinants of occupational structure excerpt

the crowding hypothesis and comparable worth although women s pay and occupational distribution have improved during the past few years it is still true that women earn considerably less than men and that their occupational distribution is substantially different because progress has been slow toward equality in the labor market some have called for a comparable worth policy proponents of this approach argue that occupational segregation contributes to the earnings disparity between women and men one theoretical justification for this position is the crowding hypothesis this paper first explains this theory and presents a method used to test its principal hypothesis it then describes an extension of this design for estimating the phenomenon that comparable worth policies address empirical studies conducted in this area are viewed and new findings are presented finally limitations of this analysis are discussed i introduction

are corporate tax rates or countries converging abstract the statutory rate and effective tax rate imposed on corporation income as well as the dispersion of these rates began to decline in the 1980s is this due to changes in the domestic determinants of corporate taxation or increases in international pressures for tax competition this paper finds clear evidence that the corporate tax rate is insulated from a country s revenue needs across countries there is no association of the expenditure gdp ratio with the corporate statutory rate and only weak evidence of a positive association with the average rate there is suggestive but not definitive evidence that the domestic role of the corporate tax as a backstop to the individual income tax is important across countries there is indeed a strong association between the top individual rate and the top statutory corporate rate there is intriguing evidence about the role of international competitive pressures on corporate taxation measures of openness are negatively associated with statutory corporate rates although not with revenues collected as a fraction of gdp strikingly larger more trade intensive countries do collect more corporate tax but this may be because these countries are more attractive venues for investment

beauty and the labor market the authors examine the impact of looks on earnings using interviewers ratings of respondents physical appearance plain people earn less than average looking people who earn less than the good looking the plainness penalty is 5 to 10 percent slightly larger than the beauty premium effects for men are at least as great as for women unattractive women have lower labor force participation rates and marry men with less human capital better looking people sort into occupations where beauty may be more productive but the impact of individuals looks is mostly independent of occupation suggesting the existence of pure employer discrimination copyright 1994 by american economic association

corporate taxation in the oecd in a wider context against the background of increased globalisation statutory corporate tax rates have shown a clear downward trend over the last two decades the sharp decline in these rates was accompanied by substantial tax base broadening and a comparable reduction in personal income tax rates only until the early 1990s this suggests that corporate tax competition is of increasing importance so far corporate tax revenues remain fairly stable but an analysis of corporate taxation in the context of the overall tax systems shows that a substantial shift towards value added taxes has taken place while the trends so far have been driven by smaller european countries recent tax reforms indicate that increasing tax competition is inducing a shift towards consumption even for larger economies

a search interpretation of male female wage differentials a general equilibrium search framework is used to examine the role of gender differences in labor market behavior patterns e g quit rates for personal reasons in determining gender wage differentials for samples of high school and college graduates from the national longitudinal survey of youth nlsy these behavioral patterns are found to be significantly different across the sexes and account for 20 30 of the wage differentials in particular they play a key role in explaining the male female wage differential that remains after controlling for the gender composition across occupations

instruments randomization and learning about development there is currently much debate about the effectiveness of foreign aid and about what kind of projects can engender economic development there is skepticism about the ability of econometric analysis to resolve these issues or of development agencies to learn from their own experience in response there is increasing use in development economics of randomized controlled trials rcts to accumulate credible knowledge of what works without overreliance on questionable theory or statistical methods when rcts are not possible the proponents of these methods advocate quasirandomization through instrumental variable iv techniques or natural experiments i argue that many of these applications are unlikely to recover quantities that are useful for policy or understanding two key issues are the misunderstanding of exogeneity and the handling of heterogeneity i illustrate from the literature on aid and growth actual randomization faces similar problems as does quasi randomization notwithstanding rhetoric to the contrary i argue that experiments have no special ability to produce more credible knowledge than other methods and that actual experiments are frequently subject to practical problems that undermine any claims to statistical or epistemic superiority i illustrate using prominent experiments in development and elsewhere as with iv methods rct based evaluation of projects without guidance from an understanding of underlying mechanisms is unlikely to lead to scientific progress in the understanding of economic development i welcome recent trends in development experimentation away from the evaluation of projects and toward the evaluation of theoretical mechanisms jel c21 f35 o19

a theory of interregional tax competition a general equilibrium model is constructed to study tax competition where local governments compete for capital by holding down property tax rates and public expenditure levels an exact definition of tax competition is provided and both the existence and nonexistence of tax competition are shown to be theoretically possible it is argued however that tax competition must occur under empirically reasonable conditions inefficiency in public production is also explicitly modeled the amount of capital used to produce a given level of public service output is shown to be greater than that which is required to minimize costs evaluated at the prices facing private firms

the impact of obesity on wages abstract previous studies of the relationship between body weight and wages have found mixed results this paper uses a larger data set and several regres sion strategies in an attempt to generate more consistent estimates of the effect of weight on wages differences across gender race and ethnicity are explored this paperjnds that weight lowers wages for white females ols esti mates indicate that a difference in weight of two standard deviations roughly 65 pounds is associated with a difference in wages of 9 percent in absolute value this is equivalent to the wage effect of roughly one and a half years of education or three years of work experience negative cor relations between weight and wages observed for other gender ethnic groups appear to be due to unobserved heterogeneity i introduction several previous studies have found among females a negative cor relation between body weight and wages there exist three broad categories of ex planations for this finding the first explanation is that obesity lowers wages for example by lowering productivity or because of workplace discrimination the sec ond is that low wages cause obesity this would be true if poorer people consume

stock market participation and the internet theory indicates that frictions e g information and transaction costs could account for the lower than expected stock market participation rates this paper examines the hypothesis that there has been a fundamental change in participation and links this change to the reduction of these frictions by the advent of the internet using panel data on household participation rates over the past decade the results show computer internet using households raised participation substantially more than non computer using households the increased probability of participation was equivalent to having over 27 000 in additional household income or over two more mean years of education

optimal portfolio choice for long horizon investors with nontradable labor income this paper examines how risky labor income and retirement affect optimal portfolio choice with idiosyncratic labor income risk the optimal allocation to stocks is unambiguously larger for employed investors than for retired investors consistent with the typical recommendations of investment advisors increasing idiosyncratic labor income risk raises investors willingness to save and reduces their stock portfolio allocation towards the level of retired investors positive correlation between labor income and stock returns has a further negative effect and can actually reduce stockholdings below the level of retired investors financial advisors typically recommend that their customers invest more in stocks than in safe assets when they are working and to shift their investments towards safe assets when they retire jagannathan and kocherlakota 1996 malkiel 1996 by contrast the standard academic models of portfolio choice merton 1969 1971 samuelson 1969 show that retirement is irrelevant for portfolio decisions if investment opportunities are constant and human capital is tradable in this case the fraction of wealth optimally invested in risky assets should be constant over the lifetime of an individual recent research building on the pioneering work by merton 1971 shows that time varying investment opportunities result in portfolio rules with an intertemporal hedging component whose magnitude depends on the investment horizon of the investor kim and omberg 1996 balduzzi and lynch 1997 brennan schwartz and lagnado 1997 brandt 1999 campbell and viceira 1999 2001 barberis 2000 with time variation in investment opportunities retirement and death play an instrumental role as events that exogenously fix the individual s investment horizon more importantly retirement also marks the time at which individuals stop working and thereafter must live off their lifetime savings and possibly transfers from this perspective retirement matters for portfolio choice

portfolio choice in the presence of background risk in this paper we focus on how the presence of background risks from sources such as labour and entrepreneurial income influences portfolio allocations this interaction is explored in a theoretical model that is calibrated using cross sectional data from a variety of sources the model is shown to be consistent with some but not all aspects of cross sectional observations of portfolio holdings the paper also provides a survey of the extensive theoretical and empirical literature on portfolio choice

on the determination of occupational attainment and mobility the underlying motivation for much of the research into the determinants of occupational attainment is to enable inferences to be made as to the relative position of various groups at a point in time or an individual s economic mobility over time in this paper we compare unordered and ordered discrete choice approaches to estimating models of occupational attainment estimates from these methods differ substantially indicating that the determination of which technique is more appropriate is an important issue the ordered method appears to be more consistent with the motivation of previous research and requires less computer time unordered models however are better able to predict occupational distribution

wage differentials employer size and unemployment the unique equilibrium solution to a game in which a continuum of individual employers choose permanent wage offers and a continuum of workers search by sequentially sampling from the set of offers is characterized wage dispersion is a robust outcome provided that workers search while employed as well as when unemployed the unique nondegenerate equilibrium distribution of wage offers is constructed for three cases 1 identical workers and employers 2 identical employers and an atomless distribution of worker supply prices and 3 identical workers and an atomless distribution of job productivities copyright 1998 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

tax competition when firms choose their organizational form should tax loopholes for multinationals be closed we analyze a sequential game between two symmetric countries when firms can invest in a multinational structure that confers tax savings governments are able to commit to long run tax discrimination policies before firms decisions are made and before statutory capital tax rates are chosen non cooperatively whether a coordinated reduction in the tax preferences granted to mobile firms is beneficial or harmful for the competing countries depends critically on the elasticity with which the firms organizational structure responds to tax discrimination incentives a model extension with countries of different size shows that small countries are likely to grant more tax preferences than larger ones along with having lower effective tax rates

social security disability insurance applications awards and lifetime income flows this article provides new evidence about the impact of social security disability insurance on male labor force participation decisions based on estimates from a structural model of applications awards and state contingent lifetime income flows the lifetime framework makes it possible to consider long term opportunity costs associated with early labor force withdrawal and the disincentive to applications resulting from the statutory waiting period before benefits may be received estimation techniques account for the self selected nature of the pool of applicants when predicting the individual specific probability of acceptance and the opportunity costs of applying

corporate tax effects on the quality and quantity of fdi this paper measures the relative importance of quality and quantity effects of corporate taxation on foreign direct investment quantity is affected if corporate taxes reduce the equilibrium stock of foreign capital in a given country quality effects arise if taxes decrease the extent to which investment contributes to the corporate tax base and the capital intensity of production depending on the sign of the quality effects the detrimental welfare effects of corporate taxation are either mitigated or aggravated we derive a number of hypotheses how corporate tax changes may affect the quality of investment our hypotheses are then tested using data from a large sample of european multinationals with regard to corporate tax effects on the corporate tax base we find that quality effects account for up to fourty per cent of the total effect with regard to corporate tax effects on labour income our results suggest that quality effects mitigate the negative quantity effect by nearly sixty percent as corporate taxes strongly increase the labor intensity of production an important implication is that governments should not exclusively care about the size of inbound fdi flows but also about their specific characteristics i e their quality

does trade liberalization trigger tax competition theory and evidence from oecd countries this article aims at assessing the empirical relevance of new economic geography models of tax competition we rely on a simple model to specify tax reactions functions which we estimate with a panel covering up to 26 oecd countries over the period 1982 to 2006 we provide striking support for the two main predictions regarding the slope and the constant of the reaction function national governments seem to adjust their corporate tax rate towards the level chosen in countries that are more populated and they tend to set higher corporate tax rates when their country enjoys a high real market potential through the latter effect trade integration exerts a positive influence on the level of corporate taxation however using a theoretically grounded index of bilateral trade integration we also show that trade liberalization gives rise to significant tax interactions in the setting of effective average tax rates in the case of european countries thus exerting a downward pressure on corporate tax rates

business taxation in a globalized world this paper addresses broad issues concerning taxes on company profit in a globalized world in which companies capital and profit can move easily between countries it considers reasons for national taxation of company profit in such a world and reviews the development of such taxes in the oecd the role played by tax havens is discussed and evidence on the responsiveness of companies to differences in taxation across countries is presented a central issue is the allocation of taxable profit between countries existing practice has no clear rationale recent proposals for fundamental reform in the eu are discussed

disability transfers and the work decision of older men the potential causal relationship between the availability and generosity of disability transfers and the nonparticipation rates of older men is often asserted and much studied parsons 1980 haveman and wolfe 1984 leonard 1986 however estimates of the magnitude of this linkage vary widely the growth in transfer availability and generosity has been credited with from 30 to 100 percent of the significant post 1960 fall in older male participation rates the disparity in these research results stems primarily from 1 alternative sources of data that differentially constrain estimation of relevant expected wage and transfer incomes 2 specifications that are unable to distinguish income transfer from labor market effects and 3 reliance on measures of health status that are endogenous to the work leisure decision this study seeks to narrow the range of estimates by addressing each of these issues our utility maximization model of work status choice assumes that workers who differ in health status choose between the mutually exclusive options of working at the wage offered for their characteristics and accepting public or private disability transfers because the income flows in the two options are censored they are estimated using switching regression techniques as expectations conditional on exogenous individual characteristics hence accounting for the potentially endogenous process that separates wage earners from transfer recipients the marginal utilities of income from the two sources are allowed to differ because of stigma effects in the estimation we adjust the choice based nature of our sample employ longitudinal earnings data to measure expected changes in as distinct from the expected level of income in the two options and use a separately estimated latent health status measure largely purged of its endogeneity with the participation decision

does privatisation of vocational rehabilitation improve labour market opportunities evidence from a field experiment in sweden this paper analyses if privatisation of vocational rehabilitation can improve labour market opportunities for individuals on long term sickness absence we use a field experiment performed by the p

cognitive abilities and portfolio choice we study the relation between cognitive abilities and stockholding using the recent survey of health ageing and retirement in europe share which has detailed data on wealth and portfolio composition of individuals aged 50 in 11 european countries and three indicators of cognitive abilities mathematical verbal fluency and recall skills we find that the propensity to invest in stocks is strongly associated with cognitive abilities for both direct stock market participation and indirect participation through mutual funds and retirement accounts since the decision to invest in less information intensive assets such as bonds is less strongly related to cognitive abilities we conclude that the association between cognitive abilities and stockholding is driven by information constraints rather than by features of preferences or psychological traits

the rise in the disability rolls and the decline in unemployment between 1984 and 2001 the share of nonelderly adults receiving social security disability insurance income di rose by 60 percent to 5 3 million beneficiaries rapid program growth despite improving aggregate health appears to be explained by reduced screening stringency declining demand for less skilled workers and an unforeseen increase in the earnings replacement rate we estimate that the sum of these forces doubled the labor force exit propensity of displaced high school dropouts after 1984 lowering measured u s unemployment by one half a percentage point steady state calculations augur a further 40 percent increase in the rate of di receipt

cross border tax effects on affiliate investment evidence from european multinationals recent studies suggest that multinational firm activities at home and abroad are positively correlated which may be due to the use of common inputs like marketing patents etc then a cost shock at one location may lead to reduced activity in all other locations within the firm in this paper we theoretically and empirically analyze national corporate tax policy in such a setting our main hypothesis is that corporate taxation at the parent location not only reduces the parent s capital stock but also lowers capital stocks at affiliates abroad using micro data on european multinational firms we confirm the hypothesis showing that a 10 percentage point increase in corporate tax rates is associated with a 5 6 decrease in the affiliate s capital stock from a welfare point of view this cross border tax effect on the capital stock gives rise to a negative fiscal externality of corporate taxation which is empirically shown to compensate a substantial fraction of the well known positive externality due to profit shifting

social interaction and stock market participation we propose that stock market participation is influenced by social interaction in our model any given social investor finds the market more attractive when more of his peers participate we test this theory using data from the health and retirement study and find that social households those who interact with their neighbors or attend church are substantially more likely to invest in the market than non social households controlling for wealth race education and risk tolerance moreover consistent with a peer effects story the impact of sociability is stronger in states where stock market participation rates are higher

disability capacity for work and the business cycle an international perspective important policy issues arise from the high and growing number of people claiming disability benefits for reasons of incapacity for work in oecd countries economic conditions play an important part in explaining both the stock of disability benefit claimants and inflows to and outflows from that stock employing a variety of cross country and country specific household panel data sets as well as administrative data we find strong evidence that local variations in unemployment have an important explanatory role for disability benefit receipt with higher total enrolments lower outflows from rolls and often higher inflows into disability rolls in regions and periods of above average unemployment in understanding the nature of the cyclical fluctuations and trends in disability it is important to distinguish between work disability and health disability the former is likely to be influenced by economic conditions and welfare programmes while the latter evolves in a slower fashion with medical technology and demographic changes there is little evidence of health disability being related to the business cycle so cyclical variations are driven by work disability the rise in unemployment due to the current global economic crisis is expected to increase the number of disability insurance claimants

disability insurance benefits and labor supply a critical input for assessing the optimal size of disability insurance programs is the elasticity of labor force participation with respect to the generosity of benefits unfortunately this parameter has been difficult to estimate in the context of the u s disability insurance program since all workers face an identical benefits schedule i surmount this problem by studying the experience of canada which operates two distinct disability insurance programs for quebec and for the rest of canada the latter program raised its benefits by 36 percent in january 1987 whereas benefits in quebec were constant i find a sizable labor supply response to the policy change my central estimates imply an elasticity of labor force nonparticipation with respect to disability insurance benefits of 0 28 0 36

the impact of nearly universal insurance coverage on health care utilization evidence from medicare the onset of medicare eligibility at age 65 leads to sharp changes in the health insurance coverage of the u s population these changes lead to increases in the use of medical services with a pattern of gains across socioeconomic groups that varies by type of service while routine doctor visits increase more for groups that previously lacked insurance hospital admissions for relatively expensive procedures like bypass surgery and joint replacement increase more for previously insured groups that are more likely to have supplementary coverage after 65 reflecting the relative generosity of their combined insurance package under medicare

estimation of equilibrium wage distributions with heterogeneity summary equilibrium search models generalize the one sided models used earlier by endogenizing the wage offer distribution attempts to estimate versions of these equilibrium n search models have been unsuccessful ironically because the predicted wage distribution did not fit the wage data in this paper we extend the applicability of search models by introducing firm heterogeneity to account for the shape of the wage density the resulting estimation problem is difficult but we propose a solution and illustrate its feasibility and performance with a monte carlo study and an application to us labour market data

the effect of implicit contracts on the movement of wages over the business cycle evidence from micro data in this paper we address the question of whether wages are affected by labor market conditions in a manner more consistent with a contract approach than with a standard spot market model from a simple implicit contract model we derive implications about the links between wages and past labor market conditions using individual data from the current population survey and the panel study of income dynamics we find that an implicit contract model with costless mobility describes these links better than either a simple spot market model or an implicit contract model with costly mobility

on the measurement of investment types heterogeneity in corporate tax elasticities this paper contributes to debates about the appropriate characterisation of heterogeneous investment types and to what extent different investment motives affect the responsiveness to corporate taxation in particular we employ and refine a methodology to better evaluate the tax elasticity of investment types using a combination of both firm specific information and sector specific information from input output tables we discuss how to classify investment as non related horizontal vertical and complex types first we point out to what extent the resulting classification depends on assumptions made by the researcher second we employ an ample set of classifications and find that non related investment reacts stronger to corporate taxation whereas horizontal investment is less responsive though significant negative tax semi elasticities turn out for the subset of manufacturing industries to address inherent characteristics of vertical and complex investment we extend the methodology and find that by and large stronger business motives reduce the tax responsiveness of investment to a larger extent given the current debates about substantial corporate tax reforms it is all the more important to recognise that corporate tax effects can vary fundamentally between countries driven by country specific differences in their composition of industries and investment types

the health and earnings of rejected disability insurance applicants applicants for social security disability benefits who fail to pass the medical screening form a natural control group for beneficiaries data drawn from the 1972 and 1978 surveys of the disabled done for the social security administration show that fewer than 50 percent of rejected male applicants work typical earnings of those that do are less than 59 percent of median earnings for other men their age these data cast doubt on recent econometric work that suggests that the disincentive effects of the social security disability program have been substantial copyright 1989 by american economic association

does medicare save lives health insurance characteristics shift at age 65 as most people become eligible for medicare we measure the impacts of these changes on patients who are admitted to hospitals through emergency departments for conditions with similar admission rates on weekdays and weekends the age profiles of admissions and comorbidities for these patients are smooth at age 65 suggesting that the severity of illness is similar on either side of the medicare threshold in contrast the number of procedures performed in hospitals and total list charges exhibit small but statistically significant discontinuities implying that patients over 65 receive more services we estimate a nearly 1 percentage point drop in 7 day mortality for patients at age 65 equivalent to a 20 reduction in deaths for this severely ill patient group the mortality gap persists for at least 9 months after admission

disability earnings income and consumption using longitudinal data for the period 1968 2005 for a sample of male household heads we determine the prevalence of disability during the working years and examine how the extent of disability affects a range of outcomes including earnings income and consumption we have seven main findings first disability rates are high we divide the disabled along two dimensions based on the persistence and severity of their work limiting condition we estimate that a person reaching age 56 has a 53 percent chance of having been disabled at least once during his working years and a 19 percent chance that he has begun a chronic and severe disability second the economic consequences of disability are frequently profound ten years after disability onset a person with a chronic and severe disability on average experiences a 68 percent decline in earnings a 32 percent decline in after tax income a 22 percent decline in food and housing consumption and a 21 percent decline in food consumption third the various economic consequences differ sharply across disability groups the outcome declines for those with a chronic and severe disability are often more than twice as large as those for the average disabled fourth our findings show the partial and incomplete roles that individual savings family support and social insurance play in reducing the consumption drop that follows disability only about half of this most disabled group reports receiving social security disability insurance or supplemental security income fifth we find a noticeable fall in earnings and income prior to the onset of a reported disability consumption also falls somewhat suggesting that future disability is partially but incompletely predictable in the short run sixth time use and detailed consumption data further indicate that disability is associated with a decline in well being seventh the quantities we have estimated combined with elasticities from the literature allow us to examine the optimality of current compensation for the disabled we find that the current compensation for our most disabled group appears to be lower than is optimal

the impact of health insurance on stockholding a regression discontinuity approach economic theory predicts that a reduction in background risk should induce financial risk taking particularly for individuals with low stock market participation costs hence health insurance coverage could affect financial risk taking by offsetting health related background risk we use a regression discontinuity design to examine whether medicare eligibility at age 65 increases stockholding in the us and find that it does so for those with college education but not for their less educated counterparts who face higher stock market participation costs our results are unlikely due to the reduction of medical expenses associated with medicare coverage because the latter does not affect bondholding

corporate tax elasticities a reader s guide to empirical findings corporate taxes exert a variety of effects on business behaviour a wealth of empirical evidence assesses the magnitude of these behavioural margins of taxation this article offers an up to date review and aims to provide common ground by computing for each distortion the semi elasticity of the corporate tax base we pay particular attention to international investment where it is not a priory clear whether marginal investment decisions or discrete locations are most important using anextension of the meta analysis of de mooij and ederveen 2003 we explore the extent to which existing studies reveal differences in effect size between the intensive and extensive margins of international investment

income risk borrowing constraints and portfolio choice economic theory suggests that uninsurable income risk and the expectation of future borrowing constraints can reduce the share of risky assets in a household s portfolio if the utility function exhibits decreasing absolute risk aversion and decreasing prudence an individual will reduce his exposure to rate of return risks when confronted with other independent risks if there are transaction costs the expectation of future borrowing constraints should induce individuals to keep a lower proportion of their wealth in the form of illiquid and risky assets the authors find support for these propositions in a cross section of italian households copyright 1996 by american economic association

unemployment insurance takeup rates and the after tax value of benefits the recent decline in the unemployment insurance ui takeup rate has puzzled researchers using administrative data with accurate information on the potential level and duration of benefits we examine whether a separating employee receives ui we find a strong positive effect of the benefit level on takeup and smaller effects of the potential duration and the tax treatment of benefits simulations indicate that the recent inclusion of ui in the income tax base can account for most of the previously unexplained decline in ui receipt

asymmetric tax competition abstract the paper analyzes nash equilibrium when two jurisdictions set tax rates on a tax base which is mobile between them population differences imply tax differences the smaller jurisdiction levies a lower tax rate in equilibrium and its residents are better off than those in the larger jurisdiction the nash equilibrium is inefficient if the two jurisdictions merged the resulting allocation would be efficient however if differences in population are great enough residents of the small jurisdiction would be made worse off by such a merger

disability insurance rejection rates and the labor supply of older workers abstract we investigate the effects of trying to mitigate moral hazard in the disability insurance di program by raising the stringency of the screening process for applicants we do so by studying a dramatic increase in rejection rates for the di program in the late 1970s which varied substantially across the us states we find that each 10 rise in denial rates led to a statistically significant 2 8 fall in labor force non participation among 45 64 year old males we also find that the denial rate increases effectively targeted their incentive effects to more able individuals according to an anthropometric measure of disability

assessing the effect of payroll taxes on formal employment the case of the 2012 tax reform in colombia in 2013 colombia implemented a tax reform that reduced payroll taxes by a total of 13 5 percentage points of wages this paper evaluates the effects of this component of the 2012 colombian tax reform on firms formal employment and average wages we construct a panel of firms based on their employees administrative records to account for the endogeneity of the treatment we use an instrumental variables technique that exploits the exogenous variation from the decisions of firms that are similar to each other in several dimensions but belong to different economic sectors based on our preferred specification we estimate a positive and significant increase in formal employment as a result of the implementation of the reform of approximately 213 000 jobs in existing pre reform firms in the long run these effects will increase to more than 600 000 jobs the effect of the reform on the average wages paid by firms was also found to be positive for some sizes of firms but the overall effect in the short run is rather small

distinguishing income from substitution effects in disability insurance a set of studies conducted over the last 15 years has produced a near consensus that the social security disability insurance system ssdi has substantial disincentive effects on the labor supply of near elderly males diminishing labor force participation increasing the sensitivity of labor force exit decisions to adverse economic shocks and encouraging those nearing retirement to claim disability benefits and subsequently transfer into the social security retirement program yet efforts by the social security administration ssa to encourage labor supply among the disabled by removing the work disincentives built into ssdi have been almost entirely unsuccessful most notably in 1999 congress authorized the ticket to work program which provides an array of inducements for current ssdi beneficiaries to take up employment including permitting a trial work period of up to nine months providing 7 75 years of ongoing medicare eligibility following return to work and providing three years of automatic benefit reinstatement when claimants workplace earnings fall below a threshold level each of these steps reduces the implicit tax placed on labor supply by the ssdi program despite these lures fewer than 1 400 0 01 percent of the 12 2 million tickets issued to date have led to successful workforce integration autor and duggan 2006

do countries compete over corporate tax rates this paper tests whether oecd countries compete with each other over corporate taxes in order to attract investment we develop two models with firm mobility countries compete only over the statutory tax rate or the effective average tax rate while with capital mobility countries compete only over the effective marginal tax rate we estimate the parameters of reaction functions using data from 21 countries between 1983 99 we find evidence that countries compete over all three measures but particularly over the statutory tax rate and the effective average tax rate this is consistent with a belief amongst governments that location choices by multinational firms are discrete we also find evidence of concave reaction functions consistent with the model outlined in the paper

economic integration and the relationship between profit and wage taxes this paper analyzes the development of the ratio of corporate taxes to wage taxes using a simple political economy model with workers and capitalists that own internationally mobile and immobile firms among other results our model predicts that countries reduce their corporate tax rate relative to the wage tax when preferences for public goods increase or when the share of capital employed in multinational firms is rising we further show how an increase in the wage share changes both the relative size of tax bases and the political influence of different income groups the predicted relationships are tested using panel data for 23 oecd countries for the period 1980 through 2004 the results of the empirical analysis support our main hypotheses

pigou tiebout property taxation and the underprovision of local public goods abstract pigou s proposition that the use of distorting taxes rather than neutral head taxes reduces public service levels is examined in this paper a simple model with a national system of competing local governments is utilized to demonstrate that the use of a distorting property tax on mobile capital decreases the level of residential public services the case where public services are an intermediate producer good is also considered

disability transfers self reported health and the labor force attachment of older men evidence from the historical record we use trends in self reported disability to gauge the impact of the growth of disability transfer programs on the labor force attachment of older working aged men our tabulations suggest that between 1949 and 1987 about half of the 4 9 percentage point drop in the labor force participation of men aged 45 54 and between one quarter and one third of the 19 9 point drop among men aged 55 64 represented a movement of men out of the labor force and onto the rolls of transfer programs targeted at the disabled since the expansion of transfer programs represents only one of the forces behind this movement these figures represent upper bounds on the impact of such programs on work force attachment

greenfield versus merger acquisition fdi same wine different bottles relying on a large foreign direct investment fdi transaction level dataset unique both in terms of disaggregation and time and country coverage this paper examines patterns in greenfield gf versus merger acquisition ma investment although both are found to seek out large markets with low international barriers important differences emerge ma is more affected by geographic and cultural barriers and exhibits opportunistic behaviours as it is more sensitive to short run changes such as a currency crisis on the other hand gf is relatively driven by long run factors such as origincountry technological and institutional development or comparative advantage these empirical facts are consistent with the conceptual distinction made between these two modes i e ma involves transfer of ownership for integration or arbitrage reasons while gf relies on firms own capacities which are linked to the origin countries attributes they also suggest that gf and ma are likely to respond differently to policies intended to attract fdi

incarceration and racial inequality in men s employment to estimate employment population ratios for black and white men with an adjustment for incarceration a factor overlooked by most research on employment inequality the authors combine data from sur

economic aspects of optimal disability benefits this paper analyzes optimal disability and retirement or welfare benefits with imperfect disability evaluation with some able workers judged disabled and some disabled workers judged able thus the levels of both disability and retirement benefits affect labor supply with anyone not working eligible for retirement benefits we analyze the optimal structure of benefits for a given disability screening mechanism and briefly consider the problem of optimal evaluations of disability evidence in the united states there is an overlap in eligibility for disability and retirement portions of social security more generally welfare is sometimes available to people denied disability benefits

homogeneous profit tax effects for heterogeneous firms in most countries profit taxation is probably much more relevant nowadays than trade liberalisation when it comes to firm level decisions about investment empirically firms are quite heterogeneous with regard to fixed costs the composition of assets tangible versus intangible machinery versus buildings etc and the financing of investments then even uniform changes in profit tax instruments cause heterogeneous responses of firm level effective tax rates and hence after tax profits we argue that with similar profit margins firms would then require pre tax profits to differ as well governments change statutory profit tax rates and by virtue of firms heterogeneity they cause stark selection effects which are mainly related to heterogeneous fixed rather than variable costs we compute costs of capital for a large sample of firms to illustrate how homogeneous changes in tax instruments hit firms differently using bureau van dijk s orbis database we illustrate that the effects of changes in statutory instruments have relatively large systematic variance components across industries within countries and also relatively large ones of firms within industries and countries

why do so few hold stocks the authors investigate why 75 percent of u s households do not hold stocks despite the equity premium and predictions of expected utility models the question is relevant for privatization asset pricing and tax progressivity issues they show that risk aversion per se heterogeneity of beliefs habit persistence time nonseparability and quantity constraints on borrowing do not account for the phenomenon a wedge between borrowing and lending rates and minimum investment requirements are plausible but empirically weak factors more promising explanations are inertia and departures from expected utility maximization there is also qualified support for nondiversifiable income risk as a contributing factor copyright 1995 by royal economic society

portfolio choice in retirement health risk and the demand for annuities housing and risky assets in a life cycle model a retiree faces stochastic health depreciation and chooses consumption health expenditure and the allocation of wealth between bonds stocks and housing the model explains key facts about asset allocation and health expenditure across health status and age the portfolio share in stocks is low overall and is positively related to health especially for younger retirees the portfolio share in housing is negatively related to health for younger retirees and falls significantly in age finally out of pocket health expenditure as a share of income is negatively related to health and rises in age

what did medicare do the initial impact of medicare on mortality and out of pocket medical spending abstract we study the impact of the introduction of one of the major pillars of the social insurance system in the united states the introduction of medicare in 1965 our results suggest that in its first 10 years the establishment of universal health insurance for the elderly had no discernible impact on elderly mortality however we find a substantial reduction in the elderly s exposure to out of pocket medical expenditure risk specifically we estimate that the introduction of medicare was associated with a 40 decline in out of pocket spending for the top quartile of the out of pocket spending distribution a stylized expected utility framework suggests that the welfare gains from such reductions in risk exposure alone may be sufficient to cover almost two fifths of the costs of medicare these findings underscore the importance of considering the direct insurance benefits from public health insurance programs in addition to any indirect benefits from an effect on health

two questions about european unemployment a general equilibrium search model makes layoff costs affect the aggregate unemployment rate in ways that depend on equilibrium proportions of frictional and structural unemployment that in turn depend on the generosity of government unemployment benefits and skill losses among newly displaced workers the model explains how before the 1970s lower flows into unemployment gave europe lower unemployment rates than the united states and also how after 1980 higher durations have kept unemployment rates in europe persistently higher than in the united states these outcomes arise from the way europe s higher firing costs and more generous unemployment compensation make its unemployment rate respond to bigger skill losses among newly displaced workers those bigger skill losses also explain why u s workers have experienced more earnings volatility since 1980 and why especially among older workers hazard rates of gaining employment in europe now fall sharply with increases in the duration of unemployment

the measurement of unemployment an empirical approach although the unemployment rate is one of the most widely cited and closely monitored economic statistics the definition and measurement of unemployment remain controversial an important issue is whether non employed persons who display a marginal attachment to the labor force for example those who are available for and desire work but are not searching for work should be classified as unemployed or non participants although this issue has been extensively debated it has never been tested empirically this paper carries out empirical tests of this and related hypotheses using a unique longitudinal data set from canada we find within the marginally attached a waiting group whose behavior indicates that they would be more appropriately classified as unemployed rather than out of the labor force the remainder of the marginally attached exhibit behavior between that of the unemployed and the balance of non participants suggesting that the desire for work among non searchers conveys substantial information about labor force attachment and future employment status our methods also apply to heterogeneity within the unemployed and we investigate behavioral variation linked to differences in job search methods and reasons for entry into unemployment although those using passive job search do exhibit behavior somewhat distinct from active searchers our results reject the practice of classifying passive job searchers as out of the labor force overall our results indicate that the non employed are very heterogeneous so that any single division into unemployment and out of the labor force is unlikely to fully capture the variety of degrees of labor force attachment this abstract was borrowed from another version of this item

the impact of economic conditions on participation in disability programs evidence from the coal boom and bust abstract we examine the impact of the coal boom of the 1970 s and the coal bust of the 1980 s on disability program participation these shocks provide clear evidence that as the value of labor market participation increases disability program participation falls for the disability insurance program the elasticity of payments with respect to local earnings is between 0 3 and 0 4 and for supplemental security income the elasticity is between 0 4 and 0 7 consistent with a model where qualifying for disability programs is costly the relationship between economic conditions and program participation is much stronger for permanent than for transitory economic shocks

does employee body weight affect employers behavior in this paper we study the possible segregation of overweight individuals already established in the labor market when firms make decisions on hiring firing and promoting most existing studies use wage equations to document wage differences but little is known about the reason for the differences and the sorting of workers using an equilibrium search model search frictions are taken into account additionally sorting is examined using a logit model we find that wage differences between workers who have a normal weight and workers who are overweight or obese can be explained by differential firm behavior with respect to both the job offer arrival rate and the probability of being promoted

an empirical equilibrium search model of the labor market in structural empirical models of labor market search the distribution of wage offers is usually assumed to be exogenous however because in setting their wages profit maximizing firms should consider the reservation wages of job seekers the wage offer distribution is essentially endogenous we investigate whether a proposed equilibrium search model in which the wage offer distribution is endogenous is able to describe observed labor market histories we find that the distributions of job and unemployment spells are consistent with the data and that the qualitative predictions of the model for the wages set by employers are confirmed by wage regressions the model is estimated using panel data on unemployed and employed individuals we distinguish between separate segments of the labor market and we show that productivity heterogeneity is important to obtain an acceptable fit to the data the results are used to estimate the degree of monopsony power of firms further the effects of changes in the mandatory minimum wage are examined

household portfolio choice and retirement this study examines household portfolio choice through the retirement transition i show that couples significantly decrease their stock allocations after retirement whereas singles allocations remain relatively unchanged reallocations are concentrated among couples in which the wife is more risk averse than her husband husbands and wives respective retirement events are followed by opposite signed changes in stock allocations these findings are consistent with a model of collective household decision making in which spouses have heterogeneous risk preferences and suggest that dynamics in the distribution of intrahousehold bargaining power generate time varying household risk aversion

property taxation nash equilibrium and market power abstract differences in tax policy arise from differences in the number of jurisdictions in a metropolitan area following wildasin 4 and bucovetsky 2 the tax rates in the jurisdictions are determined in a nash game in the tax rate the tax rate and public service level as well as the welfare of residents increase as the number of jurisdictions in the metropolis decreases

welfare enhancing technological change and the growth of obesity the theory explores how technological change can produce obesity as an unintended consequence of economic development which reduces food prices and the strenuousness of work the empirical analysis presents a specific example of how food price declines can improve health and well being even in a developed country

the impact of stricter criteria for disability insurance on labor force participation this paper studies the effect of a large scale policy change in the austrian disability insurance program which tightened eligibility criteria for men above a certain age using administrative data on the universe of austrian private sector employees the results of difference in difference regressions suggest a substantial and statistically significant decline in disability enrollment of 6 to 7 4 percentage points and an increase in employment of 1 6 to 3 4 percentage points the policy change had important spillover effects into the unemployment and sickness insurance program specifically the share of individuals receiving unemployment benefits increased by 3 5 to 3 9 percentage points and the share receiving sickness insurance benefits by roughly 0 7 percentage points

screening disability insurance applications this paper investigates the effects of stricter screening of disability insurance applications a large scale experiment was setup where in two of the 26 dutch regions case workers of the disability insurance administration were instructed to screen applications more stringently the empirical results show that stricter screening reduces long term sickness absenteeism and disability insurance applications we find evidence for direct effects of stricter screening on work resumption during the period of sickness absence and for self screening by potential disability insurance applicants stricter screening seems to improve targeting efficiency without inducing negative spillover effects to the inflow into unemployment insurance the costs of stricter screening are only a small fraction of the monetary benefits

disability screening and labor supply evidence from south africa yet research that examines the poverty reduction and labor supply effects of disability programs has taken place exclu sively in developed countries with relatively low unemployment and high labor force participa tion rates in developing countries with high unemployment rates the disincentive effect of cash transfers on labor supply has often been assumed to be economically insignificant anne case and angus deaton 1998 in this paper i provide initial evidence on and draw attention to the effect of the south africa disability grant dg program on labor supply in the context of a policy change in disability screening i use a difference in differences estimator to assess the effect of a change toward a less intensive dis ability screening on labor force nonparticipation for older individuals if screening for disability benefit programs were perfect the supply of disability benefits would be independent of labor supply decisions and only those unable to work due to health con ditions would receive benefits however the dis ability screening process is imperfect because it is in practice difficult to determine whether a person is able to work which is the typical test of eligibility for disability benefit programs recent evidence suggests that the work disincen tive effects of disability benefits are expected to

occupational pensions and job mobility in britain estimation of a random effects competing risks model we analyse transitions between pensionable jobs non pensionable jobs and other labour market states using the 1988 9 uk retirement survey we focus on the positive association between length of job tenure and pensionable status allowing for the possibility that pension scheme members are less mobile than other workers because they have persistent unobserved characteristics that predispose them towards a high degree of security in both employment and retirement we use a competing risks model with state specific random effects the model is estimated by simulated maximum likelihood
