the optimal threshold for a value added tax abstract one of the key features of a value added tax and often one of the most contentious is the threshold level of turnover at which firms are obliged to register for the tax despite its importance however the question of the appropriate level at which to set this threshold has received little analytical attention this paper first develops a simple rule characterizing the optimal threshold when firms sizes are fixed in terms of a trade off between tax revenues and collection costs it then considers in principle and by simulation the implications for the optimal threshold of the production inefficiencies implied by the differential treatment of those above and below the threshold

welfare benefits and unemployment in affluent democracies the moderating role of the institutional insider outsider divide the effect of generous welfare benefits on unemployment is highly contested the dominant perspective contends that benefits provide disincentive to work whereas others portray benefits as job sea

wage loss following displacement the role of union coverage using two canadian data sets the authors explore the role of union coverage in displaced workers wage losses while only 32 of the workers had unionized jobs prior to displacement the wage loss suffered by these workers represented about 80 of the wages lost by all displaced workers in both samples losing union status was associated with large losses whether or not a worker switched industries after displacement extrapolating the results to the united states the authors estimate that one third to one half of u s displaced workers wage losses may be due purely to the loss of union coverage

the long term costs of job displacement for young adult workers using nlsy data the authors estimate the long term costs of job displacement for young adults earnings and wage losses were large for the first three years following displacement compared to earnings losses found by other studies for more mature workers however earnings losses for these young adults were short lived with differences between observed and expected earnings narrowing considerably five years after job loss at that point the shortfall in annual earnings relative to what would have been expected absent job loss was 9 for men and 12 5 for women and the shortfall in hourly wages was 21 2 for men young workers also apparently differ from more established workers in the composition of total earnings losses for older workers total losses largely represent actual immediate earnings losses whereas for young workers the loss of opportunities for rapid earnings growth is more important

the response of firms to eligibility thresholds evidence from the japanese value added tax abstract it is common to define benefit eligibility for small business policies by restrictions on the firm size this paper documents the effects of the value added tax vat threshold in japan focusing on the incentives for a large firm to masquerade as many small firms by separately incorporating business segments a comparison of the corporate size distributions before and after the vat introduction of 1989 shows a clustering of corporations just below the threshold a pattern that is attributable to the behavioral responses to rule out the confounding influences of the changes in the company attributes over the years we applied a semiparametric density decomposition technique developed by dinardo fortin and lemieux dinardo j fortin n m lemieux t labor market institutions and the distribution of wages 1973 1992 a semiparametric approach econometrica 1996 64 1001 1044 this study suggests that the masquerading behavior by firms may be commonplace in other settings

is unemployment really scarring effects of unemployment experiences on wages joblessness leaves permanent scars on individuals they not only lose income during periods of joblessness they are also further scarred by these experiences when they find employment a spell of unemployment is found to carry a wage penalty of about 6 on re entry in britain and after three years they are earning 14 less compared to what they would have received in the absence of unemployment the scars are also carried into their second employment spell the first spell of joblessness is found to cause the most damage redundancy seems to be less stigmatising

wage losses for displaced workers many studies have shown that displaced workers experience substantial wage reductions that are strongly related to their predisplacement job tenure and experience this paper is an assessment of whether firm closures or downturns in more broadly defined labor markets drive the extreme wage losses of high tenure high experience displaced workers i show that the relatively high wage losses of high experience displaced workers are primarily due to their heightened sensitivity to downturns in their state industry and occupation however the large wage losses of high tenure displaced workers are not explained by their sensitivity to these local downturns one interpretation of these facts is that firm specialization is linked primarily to firm specific experience but not to general labor market experience

earnings losses and unemployment of displaced workers in germany data from the german socio economic panel are used to examine the experiences of german workers following job displacement due to plant closure in the year of displacement annual earnings decline

compliance costs vs tax incentives why do entrepreneurs respond to size based regulations abstract this paper studies the mechanisms behind the responses of entrepreneurs to size dependent tax regulation we exploit the value added tax vat exemption threshold in finland both tax incentives remitted vat and compliance costs frequent filing of vat reports understanding the vat system etc change at this sales based threshold in a discontinuous manner we utilize variation in both the vat rate and reporting requirements to show that the large observed sales response is caused by the compliance costs of vat rather than the level of the vat rate highlighting the key role of compliance costs among small firms and entrepreneurs

tax incidence in differentiated product oligopoly abstract we analyze the incidence of ad valorem and unit excise taxes in an oligopolistic industry with differentiated products and price setting bertrand firms both taxes may be passed on to consumers by more than 100 percent and an increase in the tax rate can increase short run firm profits and hence the long run number of firms we provide summary conditions for these effects to arise the conditions depend on demand curvatures and are written in elasticity form surprisingly the analysis largely corroborates cournot results with homogeneous demand

taxation with costly administration the concept of a tax technology is used here as providing a unified framework for analyzing both administrative activity by tax authorities and tax resisting activity by taxpayers this framework provides a simple formalization of adam smith s four components of tax costs administration substitution active noncompliance and passive compliance the model is used to derive policy implications concerning the proper measurement of the cost of public funds and concerning the criterion for optimal administration

good jobs versus bad jobs this article develops a model of noncompetitive labor markets in which high wage good and low wage bad jobs coexist minimum wages and unemployment benefits shift the composition of employment toward high wage jobs because the composition of jobs in the laissez faire equilibrium is inefficiently biased toward low wage jobs these labor market regulations increase average labor productivity and may improve welfare

who pays sales taxes evidence from french vat reforms 1987 1999 the point of this paper is to provide visual evidence of tax shifting and to measure empirically the distribution of the sales tax burden between consumers and producers for that purpose two french reforms are studied these reforms entail steep decreases of the vat rate september 1st 1987 the vat rate on car sales went down from the luxury rate of 33 33 to the full rate of 18 6 september 1st 1999 the vat rate on housing repair services went down from the full rate of 20 6 to the reduced rate of 5 5 the consumer share of the sales tax burden is 57 in the new car sales market and 77 in the housing repair services market

job search stigma effect and escape rate from unemployment this article formulates job search models incorporating certain types of the stigma effect of unemployment it is assumed that the probability of getting a job offer given the unemployment individual contacts the firm is influenced by the duration of unemployment and is justified in a signaling context the optimal search is analyzed for one sector as well as across several independent labor market segments it is shown that there are reasonably general conditions on the search environments for which both the individual reservation wage and escape rate are negative duration dependent a fact observed in empirical studies

assessing the causal effect of curbside collection on recycling behavior in a non randomized experiment with self reported outcome this paper aims at identifying the causal effect of reducing behavioral costs of participation in household waste recycling through curbside collection using propensity score matching and differences in differences estimation with individual level panel data we estimate the effect of curbside collection its variation between types of recyclables and sociodemographic background variables and its elasticity with regard to the distance to collection containers in the bring scheme condition we argue that in a quasi experimental setting dd may be systematically upward biased due to the outcome variable being self reported while ddd may be systematically downward biased in the presence of spillover effects accordingly both estimators can be combined to derive upper and lower bounds of the true effect we find that a curbside scheme has no effect on paper recycling but increases recycling participation by between 10 and 25 points for plastic and packaging moreover we find systematic treatment effect heterogeneity with regard to pre treatment distance to collection sites and individual environmental attitudes but not by socio demography the results of our analysis therefore have important implications for effective and cost efficient implementation of environmental protection policies in urban areas

the comparison between ad valorem and specific taxation under imperfect competition abstract this paper compares ad valorem and specific taxation in two models of oligopoly with and without free entry predominantly ad valorem taxation implies a relatively low consumer price high tax revenue and when entry is precluded low profits ad valorem taxation dominates specific taxation from the welfare perspective the set of circumstances under which with free entry specific taxation raises welfare is a strict subset of that in which ad valorem taxation is welfare improving and in both models the maximisation of consumer welfare subject to a binding revenue constraint requires maximum reliance on ad valorem taxation

scar effects of unemployment an assessment of institutional complementarities this article uses panel data from the survey of income and program participation sipp and the european community household panel echp for a comparative analysis of workers post unemployment earnings trajectories in the united states and 12 western european countries across the study sample of industrialized countries results of difference in difference propensity score matching show post unemployment earnings losses to be largely permanent and particularly significant for high wage and older workers as well as for women the analyses also show that negative effects of unemployment on workers subsequent earnings are mitigated through either generous unemployment benefit systems or strict labor market regulation these effects stem partly from favorable behavioral responses that prevent downward occupational and industrial mobility and partly from changes in the overall structure of labor markets favoring the transferability of worker skills between jobs these positive effects materialize despite t

the industrial mobility of displaced workers this article uses a two industry model of unemployment duration and job search to estimate rates of transition of displaced workers from unemployment to employment distinguishing between employment in a worker s previous industry and in other industries the competing risks model allows inferences about search strategies to be drawn from data concerning employment outcomes and allows tests of some fundamental implications of search theory there is evidence that improvements in the prospects for employment in their previous industry induce displaced workers to reduce search intensity or increase reservation wages in other industries

the marginal cost of public funds hours of work versus labor force participation this paper extends the theory and measurement of the marginal cost of public funds mcf to account for labor force participation responses our work is motivated by the emerging consensus in the empirical literature that extensive participation responses are more important than intensive hours of work responses in the modelling of extensive responses we argue that it is crucial to account for the presence of non convexities created by fixed work costs in a non convex framework tax and transfer reforms give rise to discrete participation responses generating first order effects on government revenue these revenue effects make the marginal cost of funds higher and we show numerically that the implications for mcf tend to be substantial

vulnerable seniors unions tenure and wages following permanent job loss in contrast to nonunion workers reemployment wages of workers displaced from unionized jobs decline with tenure on the lost job this finding cannot easily be explained by firm or industry specific human capital accumulation deferred pay policies standard matching models or a correlation between tenure and reentry rates into unionized jobs possible explanations include negative selection of senior union workers and a negative causal effect of unionism on workers alternative skills despite a much flatter predisplacement tenure wage profile displaced union workers wage losses increase with tenure at a rate comparable to or higher than those of nonunion workers

2 00 gas studying the effects of a gas tax moratorium there are surprisingly few estimates of the effects of sales taxes on retail prices especially at the firm level we consider the temporary suspension and subsequent reinstatement of the gasoline sales tax in illinois and indiana following a price spike in 2000 earlier laws set the timing of the reinstatements providing plausibly exogenous changes in the tax rates using a unique dataset of daily prices at the gas station level 70 of the tax suspension is passed on to consumers in the form of lower prices while 80 100 of the tax reinstatements are passed on to consumers some evidence suggests that these short run pass through estimates are smaller near the state borders with the tax reinstatements associated with relatively higher prices up to an hour s drive into neighboring states

social capital and finding a job do contacts matter does social capital affect labor market outcomes the prevalent use of job contacts to find work suggests that who you know is an important means of getting a good job network theories of social capital argue that well connected workers benefit because of the job information and influence they receive through their social ties although a number of studies have found a positive relationship between measures of social capital and wages and or occupational prestige little is known about the causal effect of social networks on labor market outcomes four data sets are used to reassess findings on the role of social capital in the labor market a test of causality is proposed based on the argument that if social capital variables do have a causal effect on job outcomes then workers with high levels of social capital should be more likely to use contacts to find work all else being equal results suggest that much of the effect of social capital in the existing literature reflects the tendency for similar people to become friends rather than a causal effect of friends characteristics on labor market outcomes

family change employment transitions and the welfare state household income dynamics in the united states and germany since the demise of modernization theory social scientists have sought explanations for persisting differences in the stratification of industrialized societies primarily by studying how educational and labor market institutions shape the life chances of individuals this approach undervalues two key features of any stratification system family dynamics and the welfare state employment changes changes in household composition and changes in the employment situation of a spouse or partner can all trigger large shifts in income and material well being the impact of these events is mediated by public tax and transfer mechanisms and by private actions taken by household members this comparative analysis of household income dynamics in the united states and germany shows that variations in welfare state policy produce distinct societal patterns of income mobility and furthermore shows that the relative importance of labor market events family change and welfare state policies for income dynamics depends on gender the strong interrelationship between individual incentives and the structure of opportunity produces an asymmetry in the long term impact of events the negative effects of events that reduce income generally decay over time while the effects of positive events generally persist

an empirical model of sectoral movements by unemployed workers using canadian data i investigate the relationships among sectoral mobility unemployment spells and total unemployment recent north american evidence suggests that incidence shifts toward high wage high tenure workers may increase equilibrium unemployment through decreasing sectoral mobility and increasing spells using a multiple spell transition model i find that while shifts toward such workers may have these effects composition changes that lead to higher mobility can also increase unemployment a further investigation into the relative roles of mobility and spell lengths in driving total unemployment indicates that the influence of the former is comparatively small

the desirability of commodity taxation under non linear income taxation and heterogeneous tastes abstract this paper revisits the atkinson stiglitz result on uselessness of commodity taxation in the presence of optimal non linear income taxation in a more general setup namely when tastes are heterogeneous this general analysis displays the key economic assumptions under which the atkinson stiglitz result is robust a small tax on a given commodity is desirable if high income earners have a relatively higher taste for this commodity or if consumption of this commodity increases with leisure an application to the case of savings suggests that even in the presence of optimal non linear earnings taxation there is a role for a supplemental capital income tax in the standard overlapping generation model

more and cheaper haircuts after vat cut on the efficiency and incidence of service sector consumption taxes abstract consumption tax rates targeted at specific sectors are often reformed without any empirical knowledge about the efficiency of these policies this paper sheds light on tax incidence as well as the efficiency issue the potential for welfare improving reform by studying the impact of value added taxes vat on prices and quantities of labor intensive services i utilize a vat reform targeted at a specific service sector which creates a natural experiment set up the vat for hairdressing services in finland was reduced from 22 to 8 and the previous tax treatment still applied to other labor intensive services the choice of the treatment and control groups was exogenous to circumstances in finland since these groups were selected from a wider european setting the results suggest that hairdressers cut their prices only by half of what a complete pass through would have implied and that there was hardly any adjustment in equilibrium quantity due to the reform hairdressers were able to increase their profits significantly there is important heterogeneity in the results according to firm size

why do some occupations pay more than others social closure and earnings inequality in the united states1 this article elaborates and evaluates the neo weberian notion of social closure to investigate positional inequality in the united states it argues that social and legal barriers around occupations raise the rewards of their members by restricting the labor supply enhancing diffuse demand channeling demand or signaling a particular quality of service hypotheses derived from the closure perspective are evaluated using new data that map five institutionalized closure devices licensing educational credentialing voluntary certification association representation and unionization onto 488 occupations results from multilevel models demonstrate that closure practices particularly those that generate tangible restrictions on the labor supply shape the contemporary structure of occupational earnings returns to these strategies vary across occupations but are not tightly linked to the complexity of the occupation s knowledge base if suitably elaborated closure theory thus offers a promising complemen

firm types price setting strategies and consumption tax incidence abstract we analyze price responses to large restaurant vat rate reductions in two different european countries our results show that responses in the short and medium run were clustered around two focal points of zero pass through and full pass through differences between independent restaurants and chains is the key explanation for this pattern while nearly all independent restaurants effectively ignored the tax reductions and left consumer prices unchanged a substantial fraction of restaurants belonging to chains chose a rapid and complete pass through in the longer run prices converged but primarily through a price reversion among chain restaurants the stark difference in price responses does not appear to arise because of different market characteristics such as location initial price levels meal types and restaurant segment

welfare states and the scar effects of unemployment a comparative analysis of the united states and west germany1 the article examines whether through supporting workers search for adequate reemployment the decommodification achieved by welfare state transfers reduces the longer run scar effects of unemployment drawing on employment history data from the survey of income and program participation and the german socio economic panel the analysis establishes positive effects of unemployment benefits on workers post unemployment jobs workers risks of incurring severe earnings losses of experiencing occupational mobility and of entering unstable job arrangements are considerably reduced in both the united states and west germany as workers face constrained choices in labor markets however this institutional protection of workers economic status comes at the economic cost of prolonged unemployment simulation analyses suggest that higher benefit coverage alone might account for up to 20 of the smaller cumulative disadvantages associated with unemployment for german workers

using notches to uncover optimization frictions and structural elasticities theory and evidence from pakistan we develop a framework for nonparametrically identifying optimization frictions and structural elasticities using notches discontinuities in the choice sets of agents introduced by tax and transfer policies notches create excess bunching on the low tax side and missing mass on the high tax side of a cutoff and they are often associated with a region of strictly dominated choice that would have zero mass in a frictionless world by combining excess bunching observed response attenuated by frictions with missing mass in the dominated region frictions it is possible to uncover the structural elasticity that would govern behavior in the absence of frictions and arguably capture long run behavior we apply our framework to tax notches in pakistan using rich administrative data while observed bunching is large and sharp optimization frictions are also very large as the majority of taxpayers in dominated ranges are unresponsive to tax incentives the combination of large observed bunching and large frictions implies that the frictionless behavioral response to notches is extremely large but the underlying structural elasticity driving this response is nevertheless modest this highlights the inefficiency of notches by creating extremely strong price distortions they induce large behavioral responses even when structural elasticities are small

unemployment insurance in theory and practice a hallmark of modern labor economics is the close interplay between the development of theory data sources and econometric testing the evolution of the economic analysis of unemployment insurance provides a good illustration new theoretical approaches in particular job search theory have inspired a large amount of empirical research some of it methodologically innovative and most of it highly relevant for economic policy the paper presents a broad survey and an assessment of the economic analysis of unemployment insurance as it has evolved since the 1970s

putting firms into optimal tax theory firms are for the most part absent from the modern theory of optimal taxation their disappearance dates from the foundational models developed by peter a diamond and james a mirrlees 1971 in which firms are simply mechanical vehicles for combining productive inputs into output in cost minimizing proportions in contrast firms play a central role in all modern tax systems mostly for a reason stated by richard m bird 1996 the key to effective taxation is information and the key to information in the modern economy is the corporation in most countries firms remit the majority of tax revenues to the government either with regard to taxes legally owed by businesses or through withholding of taxes legally owed by employees or other businesses even when businesses are not required to remit taxes they are often required to file information reports that can facilitate monitoring of tax liabilities the lack of a theoretical framework that features firms impedes rigorous welfare analysis of a number of important policy issues one such example is the comparative evaluation of a uniform retail sales tax rst versus a value added tax vat in the standard model these two taxes both remitted entirely by businesses are equivalent consumption taxes but most experts consider the vat to be clearly superior on administrative grounds a view echoed in the recent report of the president s advisory panel on federal tax reform 2005 we propose a simple framework in which these and other issues can be analyzed the new framework recognizes that a tax code must be backed up by an administrative and enforcement structure

the effect of a fiscal squeeze on tax enforcement evidence from a natural experiment in china abstract this paper investigates the impact of the abolition of the agricultural taxes in 2005 across china on county governments incentives for tax enforcement i show that the revenue loss of county governments was largely offset by tougher tax enforcement the incentive for vat enforcement can be weakened however if the county 1 receives a lower share of total vat revenues 2 has a broader vat tax base or 3 has more abundant sources of revenue from land sales these findings suggest that incentives of local governments can be vital to tax enforcement and to the tax capacity of a country

optimum taxation and the allocation of time abstract a theory of optimal taxation is presented building upon becker s 1965 theory of the allocation of time optimal commodity taxation is governed by factor shares in household activities any market good which requires little household time or even saves time should carry a relatively low tax rate this policy rule does not require the estimation of price elasticities and is therefore more applicable than traditional ramsey rule taxation

earnings management to avoid earnings decreases and losses this paper provides evidence that firms manage reported earnings to avoid earnings decreases and losses specifically in cross sectional distributions of earnings changes and earnings we lind unusually low frequencies of small decreases in earnings and small losscs and unusually high frequencies of small increases in earnings and small positive income we find evidence that two components of earnings cash flow from operations and changes in working capital are used to achieve increases in earnings we present two theories based on stakeholder use of information processing heuristics and prospect theory about the motivation for avoidance of earnings decreases and losses

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

price vs quantity competition in vertically related markets generalization abstract this paper generalizes the result of alipranti et al 2014 regarding the wholesale prices i prove that upstream firms always charge the wholesale prices above below their marginal costs in case of bertrand cournot competition downstream alipranti et al 2014 demonstrates this result for the case of linear demand functions and monopolist that sells its product to two retailers i relax the assumption of linear demands allow for arbitrary number of retailers and for the competition upstream

unemployment over the life cycle racial differences and the effect of changing economic conditions an analysis of the unemployment experience of white and nonwhite male heads of household was conducted using methods of partial likelihood the results show job tenure to be the most important determinant of unemployment experience but point to the complications involved in interpreting its effects when the sample studied has mixed levels of age and job quality nonwhites differ in unemployment experience from whites mostly at low tenure levels but they tend to be more sensitive to recessions at higher levels of tenure as well

penalized or protected gender and the consequences of nonstandard and mismatched employment histories millions of workers are employed in positions that deviate from the full time standard employment relationship or work in jobs that are mismatched with their skills education or experience yet little is known about how employers evaluate workers who have experienced these employment arrangements limiting our knowledge about how part time work temporary agency employment and skills underutilization affect workers labor market opportunities drawing on original field and survey experiment data i examine three questions 1 what are the consequences of having a nonstandard or mismatched employment history for workers labor market opportunities 2 are the effects of nonstandard or mismatched employment histories different for men and women and 3 what are the mechanisms linking nonstandard or mismatched employment histories to labor market outcomes the field experiment shows that skills underutilization is as scarring for workers as a year of unemployment but that there are limited penalties for workers with histories of temporary agency employment additionally although men are penalized for part time employment histories women face no penalty for part time work the survey experiment reveals that employers perceptions of workers competence and commitment mediate these effects these findings shed light on the consequences of changing employment relations for the distribution of labor market opportunities in the new economy

fuel tax incidence and supply conditions abstract the incidence of taxes on consumers and producers plays a central role in evaluating energy tax policy yet the literature testing the main predictions of the tax incidence model is sparse in this paper we examine the pass through rate of state gasoline and diesel taxes to retail prices and importantly we estimate the dependence of pass through on factors constraining the gasoline and diesel supply chains we consider several factors that alter the elasticity of supply including within state heterogeneity in gasoline content requirements refinery capacity utilization inventory constraints and variation in the demand for untaxed uses of diesel in general we find that in periods of time when the supply chain is constrained and the constraint is plausibly unrelated to shifts in demand the pass through rate of fuel taxes declines we describe several potential implications for tax policy including tax breaks during peak driving season and during times of supply disruptions such as after major hurricanes

perfect competition urbanization and tax incidence in the retail gasoline market i introduction in applied tax incidence studies it is typically assumed that prices respond one for one to changes in sales and excise taxes chernick and reschovsky 1997 pechman 1985 shepard 1976 state of wisconsin department of revenue 2004 wiese rose and schluter 1995 zupnick 1975 is this assumption reasonable despite the fundamental role of tax incidence in the study of public finance there is surprisingly little empirical analysis that sheds light on who bears the burden of taxes in this article we examine the incidence of state gasoline excise taxes using monthly price data for all 50 states in the united states over the period 1984 1999 our estimation results generally indicate full shifting of gasoline taxes to the final consumer with changes in gasoline taxes fully reflected in the tax inclusive gasoline price almost instantly we also find that the incidence of excise taxes depends on the competitiveness of retail gasoline markets e g urban vs rural markets gasoline markets in urban states typically exhibit full shifting but those in rural states demonstrate somewhat less than full shifting although the issue of sales and excise tax incidence has received considerable attention over the years most research has focused on tax incidence theory and the standard conclusion of much of this theoretical analysis is that consumers bear the full burden of any sales and excise taxes 1 based primarily on this theoretical foundation most applied incidence studies assume that sales and excise taxes are fully reflected in consumer prices and the distribution of tax burdens across income classes necessarily reflects this assumption however actual empirical testing of this assumption of full forward shifting has been surprisingly sparse 2 in important recent research poterba 1996 and besley and rosen 1999 have conducted empirical analyses of the incidence of excise taxes poterba 1996 uses city specific clothing and personal care price data covering the 1947 1977 and the 1925 1939 periods to examine the degree to which state and local retail sales taxes are shifted to consumers with two data sets based on bureau of labor statistics bls city specific consumer price indices using these bls data on tax inclusive prices poterba 1996 constructs quarterly price indices for each of 28 standard metropolitan statistical areas smsas many of these 28 smsas experienced significant changes in sales tax rates and poterba 1996 uses these tax shocks to determine the incidence of sales taxes his estimation results are somewhat variable but in general he finds for the postwar period that taxes are fully shifted to consumers in some cases he finds limited evidence of overshifting although it is never possible to reject the null hypothesis that prices rise point for point with the changes in the tax and he also finds that full shifting typically though not always occurs in the first quarter of the tax change poterba 1996 also examines tax incidence for individual smsas during the depression era and his results indicate significant differences across metropolitan areas in the degree of tax shifting for example prices on women s clothing in chicago show significant overshifting but atlanta shows negative shifting a result that does not seem plausible besley and rosen 1999 also examine the incidence of sales taxes using price data for 12 narrowly defined commodities in 155 different u s cities using quarterly price data for the period 1982 1990 issued by the american chamber of commerce researchers association accra 3 they not only find full shifting for a number of commodities but also find overshifting for more than half the products a result they attribute to imperfect competition in the retail sector while this recent empirical research has significantly expanded our understanding of the actual nature of sales and excise tax incidence we believe that our work here on gasoline excise taxes makes several contributions to the empirical literature

production versus revenue efficiency with limited tax capacity theory and evidence from pakistan to fight evasion many developing countries use production inefficient tax policies this includes minimum tax schemes whereby firms are taxed on either profits or turnover depending on which tax liability is larger such schemes create nonstandard kink points which allow for eliciting evasion responses to switches between profit and turnover taxes using a bunching approach using administrative data on corporations in pakistan we estimate that turnover taxes reduce evasion by up to 60 70 percent of corporate income incorporating this in a calibrated optimal tax model we find that switching from profit to turnover taxation increases revenue by 74 percent without reducing aggregate profits

life course risks mobility regimes and mobility consequences a comparison of sweden germany and the united states1 the analysis of intergenerational mobility has primarily used measures of social position that are functions of an individual s occupation occupation based models of social mobility however have limitations that arguably have grown in recent decades meta analysis of available evidence for sweden western germany and the united states concerning occupational mobility household income mobility job displacement union dissolution and poverty dynamics shows the limitations of the individual level occupation based career trajectory approach to life course mobility this article develops an alternative formulation at the household level which focuses on cross national variation in the extent to which societal institutions influence the rate of events with the potential to change a household s life conditions via the manipulation of incentives for mobility generating events and the extent to which they mitigate the consequences of these events through social insurance the combination of these institut

unemployment and subsequent earnings estimating scarring among british men 1984 94 this paper estimates the impact of unemployment on earnings following re employment for a large and representative sample of british men 1984 94 unemployment incidence is found to have only a temporary effect an average earnings setback of 10 on initial re engagement largely eroding over two years the effect of unemployment duration by contrast is permanent a one year spell adding a further penalty of 10 percentage points these wage penalties are least for young men and the low paid those most at risk of unemployment and greatest for prime age and highly paid men

bilateral control with vertical contracts when a manufacturer contracts secretly with competing retailers he is subject to opportunism and linear or non linear tariffs may not allow the manufacturer to maintain monopoly prices to analyse the effects of rpm o brien shaffer 1992 use a concept of contract equilibrium which concentrates on pairwise deviations thereby questioning the robustness of the analysis this paper emphasises the distinction between the contract equilibrium and standard non cooperative concepts we advocate for some caution in the use of the former concept as if overlooks an inexistence problem we then confirm the intuition that rpm can help solve the manufacturer s commitment problem this confirms that o brien shaffer s insight is robust and validates the courts reluctance against rpm

price vs quantity competition in a vertically related market this paper demonstrates that the standard conclusions regarding the comparison of cournot and bertrand competition are reversed in a vertically related market with upstream monopoly and trading via two part tariffs in such a market downstream cournot competition yields higher output lower wholesale prices lower final prices higher consumers surplus and higher total welfare than bertrand competition

quadratic engel curves and consumer demand this paper presents a model of consumer demand that is consistent with the observed expenditure patterns of individual consumers in a long time series of expenditure surveys and is also able to provide a detailed welfare analysis of shifts in relative prices a nonparametric analysis of consumer expenditure patterns suggests that engel curves require quadratic terms in the logarithm of expenditure while popular models of demand such as the translog or the almost ideal demand systems do allow flexible price responses within a theoretically coherent structure they have expenditure share engel curves that are linear in the logarithm of total expenditure we derive the complete class of integrable quadratic logarithmic expenditure share systems a specification from this class is estimated on a large pooled data set of u k households models that fail to account for engel curvature are found ro generate important distortions in the patterns of welfare losses associated with a tax increase

are workers permanently scarred by job displacements this paper investigates whether workers suffer lasting scars following job displacements using david t ellwood s 1982 terminology scars represent persistent effects whereas blemishes are transitory adjustments which dissipate over time more precisely dislocated individuals are defined as scarred if they continue to earn less or to be unemployed more than their nondisplaced counterparts even after the conclusion of a several year adjustment period

public policy towards r d in oligopolistic industries the importance of determining optimal policy towards r d cannot be exaggerated given the worldwide interest in fostering r d and given the significant differences between european and u s policies towards interfirm cooperation on r d moreover the problem is an inherently difficult one because of the complex nature of the r d process since r d is a component of fixed costs industries where it is important tend to be concentrated hence r d policy must go hand in hand with competition policy at the same time r d is like any form of investment in that it precedes the production stage hence issues of time consistency and strategic commitment inevitably arise in considering the choice of r d policy finally r d by one firm typically leads to spillovers wbich benefit other firms so that r d exhibits many of the character department of economics university college dublin belfield dublin 4 ireiatid for helpful discussions and comments we are grateful to two anonymous referees to pedro bartos steve martin massimo motta and damien neven and to participants at seminars in birmingham st andrew s and warwick at a cepr workshop on r d spillovers in lausanne at erwit 94 in caslel gandolfo eea 95 in prague the 1996 conference on industrial economics at universidad carlos iii de madrid and a meeting of the dublin economics workshop this paper was produced as part of the international economic performance programme of the centre for economic performance london school of economics supported by the u k esrc an earlier version was circulated as cepr discussion paper no 1243 see alexis jacquemin 1988 and stephen martin 1996 istics of a public good albeit one that is mostly privately produced tbe degree to which such spillovers occur and can be internalized is another crucial influence on the desirable pattem of intervention
