housing market responses to transaction taxes evidence from notches and stimulus in the uk we investigate housing market responses to transaction taxes using administrative data on all property transactions in the u k from 2004 to 2012 combined with quasi experimental variation from tax notches and tax stimulus we present two main findings first transaction taxes are highly distortionary across a range of margins causing large distortions to the price volume and timing of property transactions secondly temporary transaction tax cuts are an enormously effective form of fiscal stimulus a temporary elimination of a 1 transaction tax increased housing market activity by 20 in the short run due to both timing and extensive responses and less than half of the stimulus effect was reversed after the tax was reintroduced due to re timing because of the complementarities between moving house and consumer spending these stimulus effects translate into extra spending per dollar of tax cut equal to about 1 we interpret our empirical findings in the context of a housing model with downpayment constraints in which leverage amplifies the effects of transaction taxes

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

taxing top ceo incomes we use a firm ceo assignment framework to model the market for ceo effective labor in the model s equilibrium more talented ceos match with and supply more effort to larger firms taxation of ceo incomes affects the equilibrium pricing of ceo effective labor and hence spills over and affects firm profits absent the ability to tax profits or a direct concern for firm owners a standard prescription for high marginal income taxes emerges however given such an ability or concern the optimal marginal tax rates are much lower

claim timing and ex post adverse selection many health care treatments are not urgent and may be delayed if patients so choose because insurance coverage is typically determined by the treatment date individuals may have incentives to strategically delay treatments to minimize out of pocket costs the strategic delay of treatment a particular form of moral hazard can be an important source of subsequent adverse selection in which ex ante identical individuals select insurance coverage based on their differing accumulation of previously delayed treatments this article investigates these forces empirically in the context of the missing market for dental insurance using rich claim level data my analysis reveals that approximately 40 of individuals strategically delay dental treatments when incentivized to do so and this flexibility in delaying treatment can explain why the market for dental insurance has largely unraveled more generally the counterfactual analysis suggests features such as open enrolment periods and contracting on pre existing conditions may be helpful tools in overcoming adverse selection in insurance contexts where the timing of uncertainty is not contractible

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

positive and normative judgments implicit in u s tax policy and the costs of unequal growth and recessions calculating the welfare implications of changes to economic policy or shocks requires economists to decide on a normative criterion one approach is to elicit the relevant moral criteria from real world policy choices converting a normative decision into a positive inference as in the recent surge of inverse optimum research we find that capitalizing on the potential of this approach is not as straightforward as we might hope we perform the inverse optimum inference on u s tax policy from 1979 through 2010 and argue that the results either undermine the normative relevance of the approach or challenge conventional assumptions upon which economists routinely rely when performing welfare evaluations

continuous review inventory models where random lead time depends on lot size and reserved capacity the processing time of large orders is in many industries longer than that of small orders this renders supply lead times in such settings to be increasing in the order size yet that pattern is not re ected in existing inventory control models especially those allowing for random lead times this work aims at rectifying the situation our setting is an order quantity reorder point model with backordering where the shortage penalty is incurred per unit per unit time the processing time of each unit is random the processing time of a lot is correlated with its size for the case where lead time is proportional to the lot size we obtain a closed form solution that is unlike the classical q r model where lead time is independent of lot size no iterations are required here we also analyze a case where the processing time exhibits economies of scale in the lot size finally we consider a situation where a customer can secure shorter processing times by reserving capacity at the supplier s manufacturing facility 2000 elsevier science b v all rights reserved

exercise behavior valuation and the incentive effects of employee stock options abstract we use a large database on eso exercises to document characteristics of exercise behavior and calibrate a utility based model for measuring how differences in exercise behavior are manifested in option values and incentives option values and incentives computed from the model calibrations are compared to those computed from models used to value tradable options our analysis provides guidance to both academics and practitioners about how differences in exercise behavior and model choice affect measures of eso values and incentives and underscores the importance of gaining a thorough understanding of the underlying economic forces that affect the behavior of eso holders

external demand constraints for agricultural exports an impediment to structural adjustment policies in sub saharan african countries abstract structural adjustment programmes are being promoted throughout the developing countries the recommended policy package including price as well as non price policies is geared towards export growth and a long term sustainable balance of payments there is considerable scepticism however whether developing countries can indeed benefit from an export oriented growth strategy first rigidities in domestic output supply responses could preclude significant export growth second external demand side constraints could impede export revenue growth if a jointly promoted export led strategy resulted in world market price deterioration analysis reveals that in the case of sub saharan africa neither of the above factors should cause a failure of structural adjustment policies however the outcome of adjustment policies could be improved if commodity and country specific factors were taken into consideration

changes in income concentration taxes or macroeconomic conditions i introduction the effects of tax policy at various points in the income distribution have received increased attention from politicians and researchers in recent years both major presidential candidates in the 2000 election proposed tax cuts that involved dramatically different distributional effects former vice president al gore s plan included targeted tax cuts for the middle class president george w bush s plan provided a tax cut to all taxpayers regardless of their income president bush has been criticized for this plan as it gives the largest tax break at least in dollar value terms to those at the upper end of the income distribution what has only recently been discussed however is the fact that the ultra rich pay a much larger than proportionate share of federal income taxes feenberg and poterba 2000 report that the top 0 5 of taxpayers with the largest income tax bills paid nearly one fourth of all income taxes in 1995 a share that has increased dramatically since the early 1960s the joint committee on taxation 2001 reports that the top 1 of the income distribution will be responsible for nearly 36 of total individual income tax liability in 2001 in response to critics of his plan president bush s supporters have noted publicly that even though rich taxpayers would receive larger tax cuts in dollar value terms they would contribute an even larger share of total income tax collections after his reform although there is little controversy over the importance of ultra rich taxpayers to the tax system researchers have not reached a clear consensus as to how they react to changes in tax rates president bush s supporters imply that wealthy taxpayers respond to tax rate cuts by reporting more adjusted gross income agi either by working more and earning more money by reaping the benefits of a more prosperous economy by shifting earnings into lower tax years or by reducing noncompliance among other possibilities it is not clear which if any of these explanations is most relevant no consensus has arisen primarily because this largely empirical question has not received significant attention in the literature our research is a direct extension of the recent literature on the responsiveness of reported agi to changes in top federal income and capital gains tax rates we address these issues in a time series econometric framework first by using more recent data to reexamine earlier time series results and second by departing from earlier research and implementing a vector autore gression var technique results indicate that tax rate changes are responsible for much of the cyclical movements in the share of agi that is reported by the top 0 5 of the agi distribution but that macroeconomic conditions are at least as important our baseline results show that a 10 cut in the top federal marginal income tax rate would increase the top agi share by only 2 7 to 3 1 and a similar cut in the top capital gains tax rate would increase it by 4 to 5 section ii of the article discusses the motivation for our research and describes previous findings we continue in section iii with a description of our data and empirical methods and present time series regression results in section iv section v includes simulations from those regressions we discuss an alternative estimation strategy based on var techniques in section vi and section vii concludes ii background and literature review initiating the most recent wave of research on this topic feenberg and poterba 1993 examine data from 1951 to 1990and reveal a substantial increase in the share of agi that is reported on very high income tax returns they conclude that this is at least partly a result of tax code changes and not a result of increased capital gains furthermore they note that it is impossible to determine how much of the increase in reported income is due to different avoidance behavior to changes in behavior labor supply or to changes in returns to the factors labor and capital that high income taxpayers own

who participates in tax avoidance evidence from swedish microdata abstractthis article empirically examines why not all individuals participate in tax avoidance we use rich swedish administrative panel data on all taxpayers with a link between corporate and individual tax returns and document that few individuals utilize legal and observable tax avoidance opportunities our results show that there are several frictions in tax avoidance participation in addition to monetary benefits from tax avoidance incentives the opportunity to participate in tax avoidance access as well as information and knowledge about these opportunities awareness are important factors for the individual s tax avoidance decision we further show that tax avoidance spreads within communities the impact of the local network is stronger for non commuters who live and work in the same municipality

lot sizing and lead time decisions in production inventory systems traditionally lot sizing decisions in inventory management trade off the cost of placing orders against the cost of holding inventory however when these lot sizes are to be produced in a finite capacity production inventory system the lot size has an important impact on the lead times which in turn determine inventory levels and costs in this paper we study the lot sizing decision in a production inventory setting where lead times are determined by a queueing model that is linked endogenously to the orders placed by the inventory model assuming a continuous review s s inventory policy we develop a procedure to obtain the distribution of lead times and the distribution of inventory levels when lead times are endogenously determined by the inventory model this procedure allows to determine the optimal inventory parameters within the class of s s policies that minimize the expected ordering and inventory related costs over time we numerically show that ignoring the endogeneity of lead times may lead to inappropriate lot sizing decisions and significantly higher costs this cost discrepancy is very outspoken if the lot size based on the economic order quantity deviates significantly from desirable production lot sizes in these cases the endogenous treatment of lead times is of particular importance

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

dying to save taxes evidence from estate tax returns on the death elasticity this paper examines data from u s federal tax returns to shed light on whether the timing of death is responsive to its tax consequences we investigate the temporal pattern of deaths around the time of changes in the estate tax system periods when living longer or dying sooner could significantly affect estate tax liability we find some evidence that there is a small death elasticity although we cannot rule out that what we have uncovered is ex post doctoring of the reported date of death

integrated single vendor single buyer model with stochastic demand and variable lead time abstract in this paper we consider the single vendor single buyer integrated production inventory problem we relax the assumption of deterministic demand and assume that the lead time is varying lineraly with the lot size the lead time is composed of a lot size dependent run time and constant delay times such as moving waiting and setup times a solution procedure is suggested for solving the proposed model and numerical examples are used to illustrate the benefit of integration a sensitivity analysis is also performed to explore the effect of key parameters on lot size reorder point and expected total cost

the taxation of superstars how are optimal taxes affected by the presence of superstar phenomena at the top of the earnings distribution to answer this question we extend the mirrlees model to incorporate an assignment problem in the labor market that generates superstar effects perhaps surprisingly rather than providing a rationale for higher taxes we show that superstar effects provide a force for lower marginal taxes conditional on the observed distribution of earnings superstar effects make the earnings schedule convex which increases the responsiveness of individual earnings to tax changes we show that various common elasticity measures are not sufficient statistics and must be adjusted upwards in optimal tax formulas finally we study a comparative static that does not keep the observed earnings distribution fixed when superstar technologies are introduced inequality increases but we obtain a neutrality result finding tax rates at the top unaltered

what has been learned about labor supply in the past twenty years the main advance in the study of labor supply in the past 20 years has come in recognizing and interpreting the variety of different labor supply functions that coexist in the empirical literature a crucial theoretical distinction with important empirical payoff is that between labor supply choices at the extensive margin i e labor force participation and employment choices and choices at the intensive margin i e choices about hours of work or weeks of work for workers another important distinction is the one between a descriptive labor supply function and a structural supply function that can be the basis for out of sample policy investigations concerning responses to tax and welfare programs and evaluations of welfare losses a full understanding of the participation hours dichotomy leads to an appreciation of the importance of the problem of selection bias what is the wage to impute to a nonworking person these distinctions are a legacy of the research conducted on labor supply over the past 20 years many important empirical questions have been addressed i how strong are the effects of taxes welfare and transfer programs on labor supply ii how important is intertemporal substitution can life cycle labor supply models explain business cycle labor supply behavior iii has the consensus view of the 1960 s of high labor supply elasticities for married women and low labor supply elasticities for married men held up all of the empirical evidence assembled on labor supply must be called into question in the light of important research on the basic quality of the data conducted by analysts at the university of michigan i discuss this evidence in a concluding section except for my discussion of measurement issues i focus only on the major discoveries about which a general consensus has emerged

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

income inequality in the united states 1913 1998 this paper presents new homogeneous series on top shares of income and wages from 1913 to 1998 in the united states using individual tax returns data top income and wages shares display a u shaped pattern over the century our series suggest that the large shocks that capital owners experienced during the great depression and world war ii have had a permanent effect on top capital incomes we argue that steep progressive income and estate taxation may have prevented large fortunes from fully recovering from these shocks top wage shares were flat before world war ii dropped precipitously during the war and did not start to recover before the late 1960s but are now higher than before world war ii as a result the working rich have replaced the rentiers at the top of the income distribution

the response of deferred executive compensation to changes in tax rates abstract given the increasing use of stock options in executive compensation we examine how taxes influence the choice of compensation and document that income deferral is an important margin of adjustment in response to tax rate changes to account for this option in the empirical analysis we explore deferral by estimating how executives choice of compensation between current and deferred income depends on changes in tax policy our empirical results suggest a significant impact of taxes on the composition of executive compensation

income distribution and equilibrium multiplicity in a stigma based model of tax evasion abstract this paper incorporates continuous income distribution into the stigma based model of tax compliance the paper investigates the effect of income distribution on the existence of multiple equilibria and characterizes the conditions under which multiple equilibria emerge precisely multiple equilibria exist if taxpayer incomes are sufficiently homogeneous because the social coordination effect dominates the individual characteristics effect numerical simulations show that the main proposition is robust to allowing two step audit policies on the part of the tax agency under the presumption that the best or good equilibrium is selected whenever there are multiple equilibria as a byproduct the effect of various forms of tax reforms on the optimal two step audit policy the equilibrium compliance and fiscal revenue is analyzed

top income shares in canada recent trends and policy implications according to canadian taxfiler data over the last thirty years there has been a surge in the income shares of the top 1 top 0 1 and top 0 01 of income recipients even with longitudinal smoothing by individual using three or five year moving averages top shares fell in 2008 and 2009 but only by a fraction of the overall surge alberta british columbia and ontario have much more pronounced surges than other provinces part of the canadian surge is likely attributable to u s factors but a comprehensive explanation remains elusive even so i draw implications for policies that might achieve some support from across the political spectrum including the elimination of tax preferences that favour those with high incomes the promotion of shareholder democracy and to maintain canada s relatively high intergenerational mobility continued wide accessibility to healthcare and education

on the benefits of pooling in production inventory systems we study inventory pooling in systems with symmetric costs where supply lead times are endogenously generated by a finite capacity production system we investigate the sensitivity of the cost advantage of inventory pooling to various system parameters including loading service levels demand and production time variability and structure of the production system the analysis reveals differences in how various parameters affect the cost reduction from pooling and suggests that these differences stem from the manner in which the parameters influence the induced correlation between lead time demands of the demand streams we compare these results with those obtained for pure inventory systems where lead times are exogenous we also compare inventory pooling with several forms of capacity pooling

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

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

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

do taxes matter lessons from the 1980 s the response of the economy to two major although in important respects offsetting tax reforms has been much smaller than ardent supply side revolutionaries expected thus suggesting that a reassessment of the grounds for revolt is in order this paper offers such a reassessment by first discussing how the evidence from the tax reforms of 1981 and 1986 reflects on our understanding of the response to taxation with particular reference to savings and capital gains realizations i then reconstruct a 1992 view about how taxes affect behavior a unifying theme is that the tax system does much more than alter the relative prices of real variables it also provides incentives to misreport income restructure financial claims time transactions change the legal form of organization and so on for this reason observed low tax elasticities of real variables may be due to either low elasticities of substitution or the fact that tax policy changes opportunity sets in complex ways disentangling these explanations requires an emphasis on the transaction based nature of the tax system and the administration and enforcement of tax laws this abstract was borrowed from another version of this item

economic theory and the world of practice a celebration of the s s model it was the question of how best to balance the costs of ordering and of running out of stock against the costs of holding excess inventory that inspired kenneth arrow theodore harris and jacob marschak to introduce the s s model in 1951 in this celebratory article we show how this model not only answered important practical questions but also opened the door to a quite startling range of important and challenging follow up questions many of great practical importance and analytic depth the s s model has become one of the touchstone models of economics opening new vistas of applied economic theory to all who internalize its structure today it is universally applied to solve questions faced in inventory control the core model elements uncertainty and fixed costs of adjustment are ubiquitous which has resulted in its becoming the general purpose economic model of discrete adjustment the s s model has also become a profound source of inspiration for macroeconomists seeking to understand the role that discrete microeconomic adjustments play in macroeconomic fluctuations looking forward we foresee rapid growth in the use of s s modeling to aid households making complex and costly financial decisions such as when and how to terminate a mortgage in the projected era of household operations research new modeling challenges will arise due to enriched feedback from the world of practice

what does the taxable income elasticity say about dynamic responses to tax changes the taxable income elasticity is relevant to dynamic scoring because it broadly encompasses many ways taxpayers respond to changes in tax rates the elasticity includes for example changes in labor supply and participation savings and portfolio allocation the form of compensation the timing of income and deductions and tax evasion and avoidance on the tax base all subsumed in this one statistic this one statistic summarizes how the tax base expands or contracts in response to changes in tax rates and consequently the extent taxpayer behavior offsets the static revenue loss gain of tax rate reductions increases in contrast to conventional revenues estimates which assume that output and other key macroeconomic aggregates remain fixed when considering changes in the tax law the taxable income elasticity imposes no such constraint nevertheless some macro dynamic responses such as investment and savings related supplyside effects and crowding out are only partially captured in the taxable income elasticity and demand effects are generally not reflected at all also the taxable income elasticity generally does not account for shifting between the individual and corporate tax bases and is primarily useful to only evaluate policies that involve changes in tax rates while large is in the eye of the beholder the taxable income literature has generally found evidence of at least a modest behavioral response with some of the more recent studies suggesting a taxable income elasticity of about 0 4 this paper uses a 0 4 elasticity to simulate the revenue effect of repealing the recent reduction in the top two tax rates to 35 percent and to motivate a discussion of what the this elasticity can tell us about the dynamic response to changes in tax policy

taxpayer confusion evidence from the child tax credit we develop an empirical test for whether households understand or misperceive their marginal tax rate our identifying variation comes from the loss of the child tax credit when a child turns 17 using this age discontinuity we find that despite this tax liability increase being lump sum and predictable households reduce their reported wage income upon discovering they have lost the credit this finding suggests that households misinterpret at least part of this tax liability change as an increase in their marginal tax rate this evidence supports the hypothesis that tax complexity can cause confusion and leads to unintended behavioral responses jel d12 d14 h24 h31

alternative approaches to evaluation in empirical microeconomics four alternative but related approaches to empirical evaluation of policy interventions are studied social experiments natural experiments matching methods and instrumental variables in each case the necessary assumptions and the data requirements are considered for estimation of a number of key parameters of interest these key parameters include the average treatment effect the treatment on the treated and the local average treatment effect some issues of implementation and interpretation are discussed drawing on the labour market programme evaluation literature

permanent versus transitory tax effects and the realization of capital gains recent empirical work on captial gains implies that realizations are highly sensitive to marginal tax rates because they are based on cross section data however these estimates cannot distinguish between permanent responses to tax rate changes and the timing of realizations to take advantage of the normal fluctuations in any individual s tax rates over time the purpose of this paper is to distinguish transitory from permanent tax effects by analyzing panel data for taxpayers controlling for permanent and transitory income and other variables the estimates suggest both transitory and permanent effects although the permanent tax rate effect is not significant in all cases

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

are ceos really paid like bureaucrats a common view is that there is little correlation between firm performance and ceo pay using a new fifteen year panel data set of ceos in the largest publicly traded u s companies we document a strong relationship between firm performance and ceo compensation this relationship is generated almost entirely by changes in the value of ceo holdings of stock and stock options in addition we show that both the level of ceo compensation and the sensitivity of compensation to firm performance have risen dramatically since 1980 largely because of increases in stock option grants

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

progressive taxation in a tournament economy abstract not enough is known about the responsiveness of individuals in particular those who work under different incentives to changes in marginal tax rates we ask whether changes in tax rates are less distortionary for workers engaged in a contest to examine this potential rationale for a more progressive tax code we first model the effort decisions of workers faced with progressive taxation under tournaments and piece rates because of the difficulty identifying any distortion that may be induced by the tax code in naturally occurring data we then report on the results of a real effort experiment based on this model consistent with a behavioral approach to public finance we find that competitive tournament workers are less sensitive and hint in our discussion at the possible welfare benefits of progressive taxation in tournament economies

growth is really good for the really rich this paper analyzes the relationship between mean income and the income of the rich our methodology closely follows that of dollar and kraay 2002 but instead of looking at the bottom of the distribution we analyze the top we use panel data from the world top incomes database which collects top income data from several countries using tax returns as the raw source we define the rich as earners in the top 10 percent 1 percent 0 1 percent and 0 01 percent of the income distribution we find that economic growth is good for the rich in the sense that the mean income of the top decile of the distribution grows in the same proportion as that of the whole population however we also find that the income of earners in the top percentile of the distribution and above grows in an even larger proportion than average income that is economic growth is really good for the really rich we also find that during economic downturns the average income of top earners responds proportionally less to changes in mean income than during economic expansions our results are robust to different sample specifications

the international mobility of billionaires this paper uses data from forbes magazine s list of billionaires supplemented with other publicly available information to study the migratory behavior of the very rich billionaires are more likely to move to countries that share a language and a culture with their country of birth and to countries with larger markets higher incomes and lower capital taxes in total only 15 of self made billionaires almost all of whom are entrepreneurs migrated to another country one explanation for the modest rate of migration may be the country specificity of entrepreneurs human capital eight out of ten migrants select a destination country with higher per capita income than that of their birth country and seven out of ten move to a country with lower capital taxes

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

redistribution when avoidance behavior is heterogeneous abstract the optimal income taxation framework is extended to account for heterogeneity in avoidance behavior the optimal tax formulae are shown to be simply and intuitively modified to reflect the value of taxable income as an indicator of the need for transfers at a given skill level this effect is in addition to any effect implied by just considering additional margins of response to taxes alternative sources of heterogeneity and their likely consequences are discussed when the choice of administration is added to the model it is demonstrated that the optimal tax system may include some seemingly wasteful avoidance schemes even if they could be eliminated without any cost when an avoidance scheme is more heavily used by the needy it may provide additional redistribution without affecting standard incentive constraints

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

taxes high income executives and the perils of revenue estimation in the new economy this paper attempts to help explain the unforecasted excess personal income tax revenues of the last several years using panel data on executive compensation in the 1990s it argues that because the gains on most stock options are treated as ordinary income for tax purposes rising stock market valuations are directly tied to non capital gains income this blurred line between capital and wage income for has affected tax revenue in three ways at least for these high income people first stock performance has directly affected the amount of ordinary income that people report by influencing their stock option exercise decisions second the presence of options gives executives more flexibility in changing the timing of their reported income and appears to make them much more sensitive to the short run timing of tax changes even accounting for the stock market changes of the period third because of the tax rules on options changing the capital gains tax rate as the u s did in the late 1990s can lead individuals to exercise their options early to convert the expected future gains into lower taxed forms the data show significant evidence of each of these effects and in all three cases executives working in the new economy and high technology sectors this abstract was borrowed from another version of this item

the joint economic lot size problem a review abstract this article reviews lot size models which focus on coordinated inventory replenishment decisions between buyer and vendor and their impact on the performance of the supply chain these so called joint economic lot size jels models determine order production and shipment quantities from the perspective of the supply chain with the objective of minimizing total system costs this paper first describes the problem studied introduces the methodology of the review and presents a descriptive analysis of the selected papers subsequently papers are categorized and analyzed with respect to their contribution to the coordination of different echelons in the supply chain finally the review highlights gaps in the existing literature and suggests interesting areas for future research

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

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

lead time reduction strategies in a single vendor single buyer integrated inventory model with lot size dependent lead times and stochastic demand this paper studies alternative methods for reducing lead time and their impact on the safety stock and the expected total costs of a q s continuous review inventory control system we focus on a single vendor single buyer integrated inventory model with stochastic demand and variable lot size dependent lead time and assume that lead time consists of production and setup and transportation time as a consequence lead time may be reduced by crashing setup and transportation time by increasing the production rate or by reducing the lot size we illustrate the benefits of reducing lead time in numerical examples and show that lead time reduction is especially beneficial in case of high demand uncertainty further our studies indicate that a mixture of setup time and production time reduction is appropriate to lower expected total costs

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

the impact of separate taxation on the intra household allocation of assets evidence from the uk abstract the income tax system in the united kingdom moved from joint to independent taxation of husbands and wives income in 1990 one interesting aspect of independent taxation is the ability for households to choose the division of household assets between the two spouses this tax reform therefore creates an opportunity for households to engage in a form of tax avoidance by shifting their investment income to the spouse with the lower marginal tax rate we use family expenditure survey fes data to examine the impact of this tax reform on the magnitude of investment income shifting between spouses with different marginal tax rates we find a sizeable shift in the share and incidence of asset income claimed by wives who typically have lower marginal tax rates as well as in the incidence of the wife claiming all the household asset income indicating that households responded to this policy change by reallocating asset ownership

economic reform programmes and agricultural development macro policy sequencing in ghana 1983 1988 abstract 1983 saw the institution of an economic reform programme as a policy response to economic decline in ghana results indicate achievement of some degree of stabilization and growth agricultural performance was mixed a result partly attributed to poor macro policy sequencing this article highlights the importance of orderly macro policy sequencing for the achievement of growth and development it suggests setting structural measures within demand management measures in a mutually enhancing package consideration of social dimensions of reform programmes and measures to ameliorate hardships among vulnerable groups in initial stages of programmes is emphasized as important for the sustainability of economic reforms

does tax policy affect executive compensation evidence from postwar tax reforms abstract the trends in executive pay and labor income tax rates since the 1940s suggest a high elasticity of taxable income with respect to tax policy by contrast the level and structure of executive compensation have been largely unresponsive to tax incentives since the 1980s however the relative tax advantage of different forms of pay was small during this period using a sample of top executives in large firms from 1946 to 2005 we also find a small short run response of salaries qualified stock options and bonuses paid after retirement to changes in tax rates on labor income even though tax rates were significantly higher and more heterogeneous across individuals in the first several decades following wwii we explore several potential explanations for the conflicting impressions given by the long run and short run correlations between taxes and pay including changes in social norms and concerns about pay equality

recent trends in top income shares in the usa reconciling estimates from march cps and irs tax return data although the majority of research on us income inequality trends is based on public use march cps data a new wave of research using irs tax return data reports substantially higher levels of inequality and faster growing trends we show that these apparently inconsistent estimates are largely reconciled if the inequality measure and the income distribution are defined in the same way using internal cps data for 1967 2006 we closely match irs data based estimates of top income shares reported by piketty and saez 2003 our results imply that any inequality increases since 1993 are concentrated among the top 1 percent of the distribution

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