behavioral hazard in health insurance a fundamental implication of standard moral hazard models is overuse of low value medical care because copays are lower than costs in these models the demand curve alone can be used to make welfare statements a fact relied on by much empirical work there is ample evidence though that people misuse care for a different reason mistakes or behavioral hazard much high value care is underused even when patient costs are low and some useless care is bought even when patients face the full cost in the presence of behavioral hazard welfare calculations using only the demand curve can be off by orders of magnitude or even be the wrong sign we derive optimal copay formulas that incorporate both moral and behavioral hazard providing a theoretical foundation for value based insurance design and a way to interpret behavioral nudges once behavioral hazard is taken into account health insurance can do more than just provide financial protection it can also improve health care efficiency jel codes d03 i12 i13 i30 i38

corporate income tax competition double taxation treaties and foreign direct investment abstract in the presence of international capital mobility foreign direct investment is influenced by corporate income tax rates and the rules of how taxes paid in the host country are treated at home in this paper the exemption credit and deduction methods are considered as tax rules tax competition is modeled as a non cooperative game with respect to both corporate tax rates and the form of double taxation relief the subgame perfect equilibrium is shown to be independent of the tax rules since capital is inefficiently allocated the feasibility and the content of a cooperative contract between governments are analyzed it is argued that only the credit method requires neither compensatory payments nor fully harmonized tax rates this is consistent with the observation that tax credits are very often adopted in double taxation treaties

revealed social preferences of dutch political parties we measure the redistributive preferences of dutch political parties using unique detailed information from their election proposals by employing the inverse optimal tax method we calculate the political weights across the income distribution for each political party we find that all dutch political parties give a higher political weight to middle incomes than to the poor moreover the political weights of the rich are close to zero furthermore we detect a strong political status quo bias as the political weights of all political parties hardly deviate from the weights implied by the pre existing tax system we argue that political economy considerations are key in understanding these results

pigou meets mirrlees on the irrelevance of tax distortions for the second best pigouvian tax this paper extends the mirrlees 1971 model of optimal income redistribution with optimal corrective taxes to internalize consumption externalities using general utility structures and exploring both linear and non linear taxes it is demonstrated that the optimal second best tax on an externality generating good should not be corrected for the marginal cost of public funds since it equals one in the optimal tax system in the optimum distortions of income taxes are equal to marginal redistributional gains if the government does not have access to a non distortionary marginal source of finance the marginal cost of public funds can be either larger or smaller than one depending on subjective preferences for income redistribution the optimal second best corrective tax is then either higher or lower than the pigouvian level the findings in this paper generalize and amend prior results based on representative agent models shedding new light on the weak double dividend hypothesis and on the welfare gains of recycling revenue from environmental taxes

optimal income taxation with adverse selection in the labour market this article studies optimal linear and non linear redistributive income taxation when there is adverse selection in the labour market unlike in standard taxation models firms do not know workers abilities and competitively screen them through non linear compensation contracts unobservable to the government in a miyazaki wilson spence equilibrium adverse selection leads to different optimal tax formulas than in the standard mirrlees 1971 model because of the use of work hours as a screening tool by firms which for higher talent workers results in a rat race and for lower talent workers in informational rents and cross subsidies the most surprising result is that if the government has sufficiently strong redistributive goals welfare is higher when there is adverse selection than when there is not policies that endogenously affect adverse selection are discussed the model has practical implications for the interpretation estimation and use of taxable income elasticities which are central to optimal tax design

risk perceptions and distributional judgments abstract we examine the role of laboratory questionnaire experiments and recent applied empirical research on attitudes in understanding the relationships between people s perceptions of inequality and their perceptions of risk we consider risk in three interpretations in vacuo in day to day life and in the original position

job search and hyperbolic discounting structural estimation and policy evaluation this paper estimates the structural parameters of a job search model with hyperbolic discounting and endogenous search effort it estimates quantitatively the degree of hyperbolic discounting and assesses its implications for the impact of various policy interventions aimed at reducing unemployment the model is estimated using data on unemployment spells and accepted wages from the national longitudinal survey of youth nlsy the likelihood function explicitly incorporates all the restrictions implied by the optimal dynamic programming solution to the model both observed and unobserved heterogeneity are accounted for the results point to a substantial degree of hyperbolic discounting especially for low and medium wage workers the structural estimates are also used to evaluate alternative policy interventions for the unemployed estimates based on a model with exponential discounting may lead to biased inference on the economic impact of policies jel c6 c73 d90 j64 j68

tax perceptions and preferences over tax structure in the united kingdom do voters know their tax liabilities accurately or do they systematically misperceive them could such misperceptions influence voters choices over alternative tax structures proposed by politicians this paper assesses the accuracy of individuals tax perceptions in the uk using micro data from the british social attitudes survey 1995 and tests an empirical model of the determinants of tax structure preferences including tax misperceptions a systematic bias towards over estimation of income and expenditure tax vat liabilities is found and individ uals tax preferences appear to be both dominated by self interest and distorted by tax misperceptions whether using a traditional utility maximisation framework or a variety of public choice frameworks economists agree that consumer voters or taxpayer voters dislike taxes taxes lower the consumption possibility set and thereby utility politicians proposing higher taxes expect to lose votes unless they can persuade voters that the utility gain from the use of those taxes will exceed the tax induced utility loss of course the extent of individuals losses will depend on their circumstances and how revenues are raised the tax structure traditional tax incidence and excess burden analyses and models of political costs associated with the tax structure hettich and winer 1984 1988 each provide guidance on the extent to which different individuals may be expected to suffer and vote differently under alternative tax structures much will depend on attitudes towards and perceptions of specific taxes especially personal income taxes and consumption taxes underlying most such analyses are two common presumptions i tax preferences are dictated by self interest and ii individuals accurately assess their tax liabilities and so make informed choices two largely independent areas of literature have challenged these assumptions first models incorporating altruism

income working hours and happiness abstract in empirical analyses the effect of income on happiness tends to be underestimated by ignoring the fact that income has to be earned using the german socio economic panel our analysis confirms this tendency for men the underestimation amounts to 25

using elasticities to derive optimal income tax rates this paper derives optimal income tax formulas using compensated and uncompensated elasticities of earnings with respect to tax rates a simple formula for the high income optimal tax rate is obtained as a function of these elasticities and the thickness of the top tail of the income distribution in the general non linear income tax problem this method using elasticities shows precisely how the different economic effects come into play and which are the key relevant parameters in the optimal income tax formulas of mirrlees the optimal non linear tax rate formulas are expressed in terms of elasticities and the shape of the income distribution these formulas are implemented numerically using empirical earning distributions and a range of realistic elasticity parameters

job search and impatience workers who are more impatient search less intensively and set lower reservation wages the effect of impatience on exit rates from unemployment is therefore unclear if agents have exponential time preferences the reservation wage effect dominates for sufficiently patient individuals so increases in impatience lead to higher exit rates the opposite is true for agents with hyperbolic time preferences using two large longitudinal data sets we find that impatience measures are negatively correlated with search effort and the unemployment exit rate and are orthogonal to reservation wages impatience substantially affects outcomes in the direction predicted by the hyperbolic model

the impact of taxation on the currency of denomination decision for long term foreign borrowing and lending this paper shows the distorting effects of different tax regulations on the effective absolute and relative costs of long term borrowing in different currencies in particular if expected borrowing costs are equal before tax then the process of minimizing expected after tax borrowing costs generally involves borrowing the weakest currency

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

taxes inflation and corporate financial policy this paper examines inflation induced distortions in personal and corporate income taxes and discusses the implications for corporate dividend and financial structure policies and for shareholder unanimity the tax effects relating to capital gains and debt interest cause changes in aggregate corporate borrowing and lead to equilibrium tax relationships which differ from the zero inflation tax relationships some of the important consequences of inflation arise from inflation induced changes in the real tax rates on business and personal income the real tax rate on business income can increase because the historical cost rather than the replacement cost of inventories and of plant and equipment are used in computing taxable income e g see nelson 15 and hong 8 inflation can increase real personal taxes through the taxation of shareholder capital gains that are nominal but not real see feldstein 6 hamada 7 points out that corporate capital structures may be affected by inflation because part of nominal debt interest payments are tax deductible even though they are actually repayments of principal this paper analyzes certain inflation induced tax distortions and discusses the consequences for corporate policy the major findings include 1 real taxes associated with capital gains and losses are greater the higher the inflation rate unless inflation causes offsetting changes in statutory tax rates pretax rates of return on assets or asset holding periods 2 real capital gains tax rates can exceed real dividend tax rates but even in this case shareholders generally lose if the firm reduces capital gains by paying larger dividends financed by new share sales 3 a shareholder s ranking of alternative firm policies can change as a result of a purely neutral inflation in which case a policy which does not maximize share price will be preferred under some inflation rates 4 the lender s real tax rate on debt interest income and the borrower s real tax shelter per dollar of real interest expense depend on the inflation rate and on the nominal interest rate even if statutory tax rates are fixed 5 if the dividend tax rate differs from the capital gains tax rate for some or all investors the miller 13 equilibrium tax relationship does not generally hold with inflation and the effect of inflation on aggregate debt and equity in the economy depends on personal and corporate tax rates section i examines the impact of inflation on the taxation of capital gains and losses and of dividends and discusses the implications for dividend policy and for shareholder preferences concerning firm policies section ii examines the

optimal wage redistribution in the presence of adverse selection in the labor market in this paper we highlight a novel role played by the non linear income tax in the presence of adverse selection in the labor market due to asymmetric information between workers and firms relying on the rothschild and stiglitz equilibrium concept we show that an appropriate choice of the tax schedule enables the government to affect the wage distribution by controlling the transmission of information in the labor market this represents an additional channel through which the government can foster the pursuit of its redistributive goals

is addiction rational theory and evidence this paper makes two contributions to the modeling of addiction first we provide new and convincing evidence that smokers are forward looking in their smoking decisions using state excise tax increases that have been legislatively enacted but are not yet effective and monthly data on consumption second we recognize the strong evidence that preferences with respect to smoking are time inconsistent with individuals both not recognizing the true dife culty of quitting and searching for self control devices to help them quit we develop a new model of addictive behavior that takes as its starting point the standard rational addiction model but incorporates time inconsistent preferences this model also exhibits forward looking behavior but it has strikingly different normative implications in this case optimal government policy should depend not only on the externalities that smokers impose on others but also on the internalities imposed by smokers on themselves we estimate that the optimal tax per pack of cigarettes should be at least one dollar higher under our formulation than in the rational addiction case

can wage increases pay for themselves tests with a production function efficiency wage theories predict that companies that pay high wages will have higher productivity from high work effort low turnover and other efficiency enhancing effects this paper uses the pims line of business data set to test whether high wage businesses are more productive relative wages were measured by managers assessments of their relative compensation holding worker quality constant a positive relation was found between changes in relative wages and changes in total factor productivity the elasticity of output with respect to wages was of the magnitude predicted by efficiency wage theories also consistent with efficiency wage theories the relationship between changes in wages and changes in productivity was weaker at businesses with high unionization results from two additional data sets imply that high wages are not merely measuring high human capital copyright 1992 by royal economic society

some observations on capital structure and the impact of recent recapitalizations on share prices this paper discusses two fundamental issues in capital structure theory and analyzes the recent recapitalizations of phillips and unocal it is shown that a value maximizing capital structure may be inconsistent with shareholder utility maximization and that the miller debt and taxes equilibrium may be inconsistent with a complete capital market in spite of these and other unresolved issues the markets s reactions to the recent recapitalizations of phillips and unocal are consistent with the predictions of capital structure theory except for small redistribution effects against bondholders the recapitalizations per se had no positive impact on common stock values

efficiency wages and industry wage differentials a comparison across methods of pay efficiency wage considerations should be less important for piece rate pay than for time wages therefore if industry wage differentials reflect efficiency wage factors then these pay differences should be less sizable and have less explanatory power for piecework than for timework we test this proposition using wage data for male production workers employed in the swedish metalworking industries in 1985 the data are partitioned into two groups of workers in our preferred sub sample of workers who received pay under both piece rates and time wages our results are uniformly consistent with efficiency wage implications for industry wage differentials for the subsample of workers who received pay under either piece rates or time wages industry wage differentials are of equal importance under either pay scheme these latter results however may also be influenced by unaccounted for sorting of workers and employers across methods of pay overall our examination of industry wage differentials across m

the effect of taxes on labour in efficiency wage models abstract this paper analyses the effects of labour taxation on wage and employment in a moral hazard efficiency wage model where effort is a continuous variable and workers are risk averse in the model examined ad valorem and specific taxes on labour do not have the same consequences on the real wage both taxes have a negative effect on employment but the imposition of a specific tax causes an increase in the net real wage including firms to raise the quality of their workers these results are compared with those obtained in other versions of the shirking efficiency wage model

gasoline prices fuel economy and the energy paradox abstract policymakers often assert that consumers undervalue future gasoline costs when they buy automobiles we test this by measuring whether relative prices of vehicles with different fuel economy ratings fully adjust to variation in gasoline prices vehicle prices move as if consumers are indifferent between 1 00 in discounted future gas cost and 0 76 in vehicle purchase price we show how corrections for endogenous market shares and utilization measurement error and different gasoline price forecasts affect the results we also provide unique evidence of sticky information vehicle markets respond to changes in gasoline prices with up to a six month delay

which commodity taxes should supplement the income tax the analysis takes as its point of departure a continuum of consumers economy in which an optimum income tax exists and is the only tax instrument in operation the welfare effects of introducing small excise taxes to supplement the income tax are then explored essential in this context are changes in the tax distortions of work incentives it is shown that a commodity should be taxed or subsidized depending on whether it is positively or negatively related to leisure in a sense which is precisely defined the results are related to earlier contributions to the literature on direct versus indirect taxation the history of debates on the proper roles of direct and indirect taxation goes back at least to the days of gladstone as well described by atkinson 1977 the prevailing political opinion of the balance between the two types of taxes has varied over time at present the swing in a number of european countries seems to be in favour of reforms towards tax systems which rely more heavily on indirect taxation and less on income taxation in view of this long economic political record it is not surprising that the choice between income tax and commodity taxes has also become an important subject in tax theory an early contribution to the understanding of this issue was corlett and hague 1953 54 their main model considers a three good economy containing leisure and two taxed commodities there is only one consumer or a population of identical consumers labour is the only source of income producer prices are fixed the government s revenue requirement is given the starting point of the analysis is a situation in which the two commodities are taxed at uniform rates the question which is analyzed is then how the government can raise welfare by slightly differentiating the tax rates the answer which is derived is that the consumer good which is the stronger substitute for labour complement with leisure should be taxed at

do women shy away from competition do men compete too much we examine whether men and women of the same ability differ in their selection into a competitive environment participants in a laboratory experiment solve a real task first under a noncompetitive piece rate and then a competitive tournament incentive scheme although there are no gender differences in performance men select the tournament twice as much as women when choosing their compensation scheme for the next performance while 73 percent of the men select the tournament only 35 percent of the women make this choice this gender gap in tournament entry is not explained by performance and factors such as risk and feedback aversion only playa negligible role instead the tournament entry gap is driven by men being more overconfident and by gender differences in preferences for performing in a competition the result is that women shy away from competition and men embrace it

non welfarist optimal taxation and behavioral public economics research in behavioral economics has uncovered the widespread phenomenon of people making decisions against their own good intentions in these situations the government might want to intervene indeed individuals might want the government to intervene to induce behavior that is closer to what individuals wish they were doing the analysis of such corrective interventions through taxes and subsidies might be called behavioral public economics however such analysis where the government has an objective function that is different from that of individuals is not new in public economics in these cases the government is said to be non welfarist in its objectives and there is a long tradition of nonwelfarist welfare economics especially the analysis of optimal taxation and subsidy policy where the outcomes of individual behavior are evaluated using a preference function different from the one that generated the outcomes the object of this paper is to first of all present a unified view of the non welfarist optimal taxation literature and secondly to present behavioral public economics as a natural special case of this general framework

equilibrium wage dispersion and interindustry wage differentials this paper develops a search theoretic explanation of interindustry wage differentials given coordination problems in the labor market the probability of filling a vacancy is an increasing function of the wage offered in equilibrium firms that find vacancies more costly will offer higher wages the model thus explains the persistence of interindustry wage differentials and their correlation with industry average capital labor ratio and profitability additionally the model predicts that high wage firms will receive more applications per job opening and that wages in the labor market will behave as strategic complements

using differences in knowledge across neighborhoods to uncover the impacts of the eitc on earnings we develop a new method of estimating the impacts of tax policies that uses areas with little knowledge about the policy s marginal incentives as counterfactuals for behavior in the absence of the policy we apply this method to characterize the impacts of the earned income tax credit eitc on earnings using administrative tax records covering all eitc eligible lers from 19962009 we begin by developing a proxy for local knowledge about the eitc schedule the degree of sharp bunching at the exact income level that maximizes eitc refunds by individuals who report self employment income the degree of self employed sharp bunching varies signi cantly

miller s irrelevance mechanism a note this note attempts to clarify miller s 12 capital structure irrelevance mechanism using a geometric edgeworth box diagrams presentation such an exercise is useful because miller s proposition is founded on analytically complex equilibrium arguments that tend to mask the intuition and logic behind his result since miller s original discussion unnecessarily assumed a zero tax on equity income and since miller did not prove his clientele effects rigorously we also focus our attention on the deangelo and masulis 8 9 henceforth d m generalization of the miller model the d m framework is also important because it assumes a proportional tax code as we shall see whether the tax code is proportional or progressive is an important factor in understanding miller s proposition

international capital structure equilibrium this paper develops a theory of capital structure in an international setting with corporate and personal taxes we generalize the miller analysis to an international equilibrium characterized by differential international taxation and inflation in otherwise perfect international capital markets our analysis highlights the key role that corporate tax arbitrage plays in generating an international capital structure equilibrium and we set forth a number of mechanisms for tax arbitrage transactions we close the paper by outlining some implications of our analysis for national differences in capital structure the international fisher effect and international tax effects on yield differentials among major questions regarding corporate capital structure which arise in an international setting are how or whether multiple tax jurisdictions and multiple currencies affect firm financing decisions and the international bond market equilibrium we examine some of these questions by way of generalizing miller s 1977 debt and taxes model into an international setting this setting allows for different tax regimes across countries as well as the possibility of differential inflation across currencies with consequent exchange rate movements in the first part of this paper we find that an international miller type equilibrium obtains under differential international taxation with capital market conditions which are otherwise analogous to those required for a domestic miller equilibrium our analysis particularly highlights the role that corporations play in miller s analysis as vehicles for tax arbitrage we show that if corporations engage in international tax arbitrage transactions on an equal footing no optimal capital structure exists for individual firms consequently without further restrictions differences in international tax rates alone are incapable of dictating a particular capital structure for an individual firm in the second part of the paper we extend the analysis to consider differential inflation rates with a consequent exchange rate movement and draw additional implications for the international analog of the miller equilibrium with differential inflation and taxation we begin by showing the existence of the international fisher effect for both equity and bonds although inflation and or exchange rate movements may affect real corporate tax subsidy rates and real

optimal taxation when people do not maximize well being abstract i derive the optimal nonlinear income tax when individuals do not necessarily maximize their own well being this generates a corrective argument for taxation optimal marginal taxes are higher lower if individuals work too much too little from a well being point of view i allow for multidimensional heterogeneity and derive the optimal tax schedule in terms of measurable sufficient statistics one of these statistics measures the degree to which individuals fail to optimize their labor supply i empirically estimate this by using british life satisfaction data as a measure of well being i find that low income workers tend to work too little and high income workers too much providing a motive for lower marginal tax rates at the bottom and higher marginal tax rates at the top of the income distribution

optimal non linear income taxation for the alleviation of income poverty there has been much discussion recently of structuring tax and transfer programs to ensure that resources go to the poor with minimal leaks to the nonpoor the poor have no incentive to earn income with 100 percent marginal tax rates but how high or low the marginal rate of taxation should be and how they should vary with income is a complex issue and opinions vary social security schemes that withdraw benefits represent an extremely high effective marginal tax rate other schemes call for relatively low marginal tax rates at the bottom of the income distribution which tax transfer schedule does most to reduce poverty the issue is one of optimal nonlinear income taxation the authors show that one of the key theoretical results of the welfarist literature is overturned if it is desirable for everybody to work the optimal marginal tax rate on the very poorest individuals is strictly negative they argue that the nonwelfarist perspective points toward lower marginal tax rates in the lower part of the income distribution than does the welfarist perspective but numerical simulations suggest that the effect is of limited quantitative significance using conventional functional forms and parameter values optimal marginal tax rates on the poor are in the 60 70 percent range

supervision and wages across industries this paper uses supervision data from a supplement to the 1977 wave of the panel survey of income dynamics to examine differences in supervision and wages across industries and to evaluate relationships between supervision practices and interindustry wage differentials the results demonstrate that workers in high wage industries are supervised with equal or greater stringency than secondary sector workers further the results offer no evidence that interindustry differences in monitoring contribute to interindustry wage differentials such findings appear to contradict explanations for industry wage premiums that are motivated by efficiency wage models of shirking copyright 1993 by mit press

understanding welfare stigma taxpayer resentment and statistical discrimination abstract welfare stigma is widely regarded to be of central importance in understanding the impact of welfare programs in their goal of alleviating poverty it affects both the decision to take up benefits and the well being of those who actually do this paper develops alternative models of the determinants of welfare stigma we identify two views a statistical discrimination approach and a taxpayer resentment view we discuss how each may be formalized and derive their implications we then examine what they imply about the relationship between stigma and program design

income happiness and the disutility of labor abstract we re examine the claim that the income effect on happiness is downward biased because higher income demands more work effort we find no evidence of an underestimation because the impact of working hours on happiness is rather small and hill shaped

interest rates inflation and taxes the foreign connection abstract in this note it is shown that the existence of taxes on nominal interest receipts in an international setting introduces a non neutrality in that a change in expected inflation in one country must change at least one expected real interest rate or the path of the real exchange rate

optimal sin taxes abstract we investigate sin taxes on unhealthy items such as fatty foods that people may by their own reckoning consume too much of we employ a standard optimal taxation framework but replace the standard assumption that all consumers have 100 self control with an assumption that some consumers may have some degree of self control problems we show that imposing taxes on unhealthy items and returning the proceeds to consumers can generally improve total social surplus because such taxes counteract over consumption by consumers with self control problems while at the same time they naturally redistribute income to consumers with no self control problems who consume less such taxes can even create pareto improvements finally we demonstrate with some simple numerical examples that even if the population exhibits relatively few self control problems optimal taxes can still be large

relativity inequality and optimal nonlinear income taxation how does concern for consumption relative to others relativity affect the structure of optimal nonlinear income taxation our article provides three sets of answers to this general question first it supports the conclusion in the literature that relativity leads to higher marginal tax rates in doing so it both generalizes some of the conditions under which this result is obtained in the literature and fleshes out the detailed structure for optimal marginal tax rates for specific functional forms for distribution utility function and social welfare function second the article goes beyond the literature and examines the impact of relativity on the progression of optimal marginal tax rates by and large we find support for greater progressivity defined as the steepness of the rise of the marginal tax rate schedule as relativity concern increases third none of the papers in the literature to our knowledge examines the interplay of relativity and inequality in determining the optimal structure of income taxes our special analytical cases and more general numerical calculations support the conclusion that higher inequality dampens the positive impact of greater relativity on the level and the progression of marginal tax rates more work is needed to further explore this interaction between relativity and inequality that our analysis has uncovered

debt and taxes abstract the extreme reliance on debt that has been a persistent feature of corporate finance in contemporary japan is at least partially due to low personal tax rates this statement is supported by comparison of japan and u s taxes based on the taxes and failure cost theory of finance

multinational capital structure and financial flexibility abstract we address multinational capital structure decisions when firms have varying degrees of financial flexibility for shifting income and or tax shields between subsidiaries we find 1 firms can use leverage to dramatically reduce negative valuation effects from operating in a high tax country 2 financial flexibility is a key determinant of optimal capital structure acting as both a substitute and a complement for leverage 3 multinational firms derive a synergistic effect from financial flexibility which can enhance their value beyond that for a single country firm from a low tax jurisdiction and 4 optimal capital structure typically differs substantially across subsidiaries with each having positions in multiple currencies

banks firms and the relative pricing of tax exempt and taxable bonds abstract the traditional analysis of the relative pricing of tax exempt and taxable debt is a habitat theory of the term structure of interest rates in the traditional analysis the preferences of investors for particular maturities of debt lead to unique pricing relations at every point on the yield curve which are indicative of investor marginal tax brackets recent work by fama 1977 suggests that banks are potential arbitrageurs across tax exempt and taxable bond markets which force a particular equilibrium on the pricing of short term bonds miller 1977 suggests that the choice of debt or equity financing by firms in the aggregate forces a similar equilibrium on the pricing of all tax exempt and taxable bonds this paper exploits the institution of regulation q and its effects on the banking system to bring evidence to bear on the predictions of these three models

debt taxes and international equilibrium abstract this paper employs an extended miller model to analyze capital structure decisions of individual firms in a two country setting miller equilibria are generally not consistent with an international equilibrium if the tax subsidy of debt differs across countries the most obvious reason for differential tax subsidies is differences between national corporate tax rates we also identify differential tax subsidies of debt if inflation rates differ across countries for both cases we examine the adjustment process from national equilibria to an international equilibrium without and with barriers to international investment we derive the relationship between the equilibrium yields on debt and equity in the two countries and discuss the fisher hypothesis that real returns do not depend upon inflation in a two country miller world

poverty alleviation and tax policy abstract this paper examines public good provision and tax policy optimal non linear income taxation and linear commodity taxation when the government departs from purely welfarist objective function and seeks to minimise poverty this assumption reflects much policy discussion and may help understand some divergences of practical tax policy from lessons in optimal tax analysis in contrast to atkinson and stiglitz j public econom 6 1976 55 it may be optimal to use differentiated commodity tax rates including the taxation of savings even if preferences are separable in goods and leisure the optimal effective marginal tax rate at the bottom of the distribution may be negative suggesting that wage subsidy schemes can be optimal finally optimal provision of a public good is analysed under poverty minimisation

an equilibrium analysis of debt financing under costly tax arbitrage and agency problems in his recent paper merton miller 12 extends the notion of tax induced differential returns on securities into a general equilibrium framework in which firms make adjustments in the supply of corporate debt in an environment of progressive personal taxation the interest rates on taxable corporate bonds are greater than rates on tax exempt securities so as to compensate investors for the associated tax burden on the supply side value maximizing firms have an incentive to issue additional debt so long as the personal tax induced compensation is less than the tax savings from interest payment deductions at the corporate level miller argues that in the final equilibrium the interest rate differential between taxable and tax exempt bonds exactly reflects the tax advantage of debt financing at the corporate level thus the tax subsidy disappears in its entirety and we are back to an environment in which corporate leverage is inconsequential to the value of any particular firm what emerges in equilibrium is merely an optimal debt equity ratio for the corporate sector as a whole 1 miller derives this invariance proposition under the following assumptions 1 progressive personal tax rates reach a maximum at a level beyond the corporate tax rate 2 no tax arbitrage by individuals and firms is allowed 3 there is a personal tax rate differential in favor of income from stocks and 4 the opportunity for riskless borrowing and lending exists 2 indeed miller s equilibrium analysis is based on a zero effective personal tax rate on income from stocks but

cellular service demand biased beliefs learning and bill shock by april 2013 the fcc s recent bill shock agreement with cellular carriers requires consumers be notied when exceeding usage allowances will the agreement help or hurt consumers to answer this question we estimate a model of consumer plan choice usage and learning using a panel of cellular bills our model predicts that the agreement will lower average consumer welfare by 2 per year because rms will respond by raising monthly fees our approach is based on novel evidence that consumers are inattentive to past usage meaning that bill shock alerts are informative and advances structural modeling of demand in situations where multipart taris induce marginal price uncertainty additionally our model estimates show that an

does unmeasured ability explain inter industry wage differentials this paper provides empirical assessments of the two leading explanations of measured inter industry wage differentials 1 true wage differentials exist across industries and 2 the measured differentials simply reflect unmeasured differences in workers productive abilities first we summarize the existing evidence on the unmeasured ability explanation second we construct a simple model which shows that if matching is important then endogenous job change decisions can create important self selection biases even in first differenced estimates of industry wage differentials third we analyze a sample that approximates the experiment of exogenous job loss we find that i the wage change experienced by a typical industry switcher closely resembles the difference in the relevant industry differentials estimated in a cross section and ii pre displacement industry affiliation plays an important role in post displacement wage determination

capital budgeting investment project valuation and financing mix methodological proposals abstract a firm using a discount rate defined at the corporate scale as a weighted average cost of capital wacc may have to value projects subject to a different tax rate from the one used to calculate its discount rate moreover to determine the economic value of a project the wacc and arditti levy methods need to be adjusted if the firm allocates to this project a loan representing proportionally more or less than the fraction corresponding to the target debt ratio defined by the firm for projects in the same class of risk we first propose a method which corresponds to the adjustment of standard wacc calculations the formulation adopted generalized atwacc method has the advantage of being independent of any consideration related to debt ratios we then develop a consistent adaptation of the arditti levy method adapted btwacc method but it does not possess the simplicity of that of the generalized atwacc method

purchasing power interest rate parities and the modified fisher effect in presence of tax agreements abstract this paper shows that in a world with different rates of inflation and taxation in the presence of an international tax agreement the simultaneous coexistence of the purchasing power parity mechanism the interest rate parity mechanism and the revised fisher effect is impossible the analysis reveals a possible inherent instability of interest rates and exchange rates generated by inflation this instability is greater the larger the tax rate differentials among countries

the effects of capital controls on international capital flows in the presence of asymmetric information abstract this paper examines the effects of capital controls on the volume and composition of international capital flows in the presence of asymmetric information in the two period small open economy model stochastic second period output depends on the level of first period investment which cannot be verified by international investors domestic agents obtain external funding by borrowing on international capital markets and by selling equity to international investors the paper investigates the effects of various capital controls on the debt equity choice domestic investment and welfare controls on capital inflows are shown to shift the composition of flows from fixed income instruments towards equity and to reduce the overall volume of inflows

the effect of taxes and depreciation on corporate investment and financial leverage this paper provides an analysis of the effect of corporate and personal taxes on the firm s optimal investment and financing decisions under uncertainty it extends the deangelo aad masulis capital structure model by endogenizing the firm s investment decision the authors results indicate that when investment is allowed to adjust optimally the existing predictions about the relationship between investment related and debt related tax shields must be modified in particular the authors show that increases in investment related tax shields due to changes in the corporate tax code are not necessarily associated with reductions in leverage at the individual firm level in cross sectional analysis firms with higher investment related tax shields normalized by expected earnings need not have lower debt related tax shields normalized by expected earnings unless all firms utilize the same production technology differences in production technologies across firms may thus explain why the empirical results of recent cross sectional studies have not conformed to the predictions of deangelo and masulis

employment hours of work and the optimal taxation of low income families the optimal design of low income support is examined using a structural labour supply model the approach incorporates unobserved heterogeneity fixed costs of work childcare costs and the detailed non convexities of the tax and transfer system the analysis considers purely pareto improving reforms and also optimal design under social welfare functions with different degrees of inequality aversion we explore the gains from tagging and also examine the case for the use of hours contingent payments using the tax schedule for lone parents in the uk as our policy environment the results point to a reformed non linear tax schedule with tax credits only optimal for low earners the results also suggest a welfare improving role for tagging according to child age and for hours contingent payments although the case for the latter is mitigated when hours cannot be monitored or recorded accurately by the tax authorities acknowledgements this study is part of the research program of the esrc centre for the microeconomic analysis of public policy at the ifs we thank stuart adam mike brewer roger gordon guy laroque ian preston emmanuel saez florian scheuer seminar participants at harvard mit jerusalem niesr sole and participants in the mirrlees review the editor and the referees for helpful comments we are alone responsible for all errors and interpretations

negative marginal tax rates and heterogeneity the bulk of the theory of optimal taxation recommends that the marginal tax rate be everywhere positive labor supply is distorted downwards compared with laissez faire the conditions under which the result holds continuous labor supply or intensive margin unobserved productivity constant opportunity cost of work utilitarian planner with a redistributive motive towards lower incomes have been thoroughly investigated jesus seade 1977 1982 ivan werning 2000 martin f hellwig 2007 the purpose of the present paper is to describe how negative marginal tax rates can be optimal keeping with the intensive set up largely studied in the literature when there are multiple dimensions of heterogeneity indeed james a mirrlees 1976 in its section iv indicates along a line that will be pursued further here that the sign of the marginal tax rate cannot be predicted when the agents in the economy differ along several dimensions of heterogeneity workers differ in both their productivities and opportunity costs of work under utilitarianism heterogeneity comes into play through its impact on cardinal utilities how social weights or marginal utilities of income vary with income determines the shape of the optimal tax scheme conditionally on income utility and more importantly its derivative with respect to income may either decrease or increase with work opportunity costs this may vary according to circumstances depending on whether the cost is associated with poor living conditions i e a handicap or reflects a taste for leisure or opportunities outside the labor market such as gardening at home or black market activities for a given income the social weight is proportional to the expected marginal utilities where the expectation is taken over the distribution of work opportunity costs at this income level therefore the social weight curve depends on both the specification of the cardinal utility function and on how the distribution of work opportunity costs changes with income the fact that heterogeneity can blur the redistribution motive through the possible correlation between ability and onerousness of work has been discussed in models where agents have a finite number of types a pioneer work is that of joseph e stiglitz 1982 who shows that the high skilled individual should face a negative marginal tax rate if the low skilled individual s upward incentive constraint binds which is the case if social weights are increasing in type the importance of this observation for policy was pointed out in katherine cuff 2000 who is the first to explicitly link social weights to the opportunity cost of work using alternative choices of cardinal utilities in a model with four types combining two values for productivity and two values for the cost of work robin boadway et al 2002 showed how it can be optimal to have binding upward incentive constraints when high opportunity costs are associated with small social weights

choice inconsistencies among the elderly evidence from plan choice in the medicare part d program we evaluate the choices of elders across their insurance options under the medicare part d prescription drug plan using a unique data set of prescription drug claims matched to information on the characteristics of choice sets we document that elders place much more weight on plan premiums than on expected out of pocket costs value plan financial characteristics beyond any impacts on their own financial expenses or risk and place almost no value on variance reducing aspects of plans partial equilibrium welfare analysis implies that welfare would have been 27 higher if patients had all chosen rationally

foreign currency denominated debt an empirical examination we examine the determinants of debt issuance in 10 major currencies by large u s firms using the fraction of foreign subsidiaries and tests exploiting the disaggregated nature of our data we find strong evidence that firms issue foreign currency debt to hedge their exposure both at the aggregate and the individual currency levels we also find some evidence that firms choose currencies in which information asymmetry between domestic and foreign investors is low we find no evidence that tax arbitrage liquidity of underlying debt markets or legal regimes influence the decision to issue debt in foreign currency

ownership agency and wages an examination of franchising in the fast food industry this paper estimates the difference in compensation between company owned and franchisee owned fast food restaurants the contrast is of interest because contractual arrangements give managers of company owned outlets less of an incentive to monitor and supervise employees estimates based on two data sets suggest that employee compensation is slightly greater at company owned outlets than at franchisee owned outlets the earnings gap is 9 percent for assistant and shift managers and 2 percent for full time crew workers furthermore the tenure earnings profile is steeper at company owned restaurants these findings suggest that monitoring difficulties influence the timing and generosity of compensation

behavioral economics and public policy a pragmatic perspective the debate about behavioral economics the incorporation of insights from psychology into economics is often framed as a question about the foundational assumptions of economic models this paper presents a more pragmatic perspective on behavioral economics that focuses on its value for improving empirical predictions and policy decisions i discuss three ways in which behavioral economics can contribute to public policy by oering new policy tools improving predictions about the eects

global convergence of financing policies evidence for emerging market firms as globalization spreads one of the key challenges that emerging market firms face is how to finance their growth opportunities using data from close to 10 000 firms from more than 30 emerging markets this paper investigates how over time leverage is determined by firms business models and also by the overall country environment i find significant changes over the last two decades in the early 1990s country characteristics dominated firm characteristics and it was difficult for firms to overcome the limitations of their domestic environment as emerging markets became better integrated with the world economy the importance of firm characteristics has increased at the end of the sample period emerging market capital structure determinants resemble those of developed markets and country characteristics have become less important in explaining financing structures i also show how over the last two decades the maturity structure of debt has changed and that in recent years firms with more tangible assets are able to attract more debt financing overall i conclude that financing choices in emerging markets are now being made in the same way as in developed markets this means that emerging market firms now rely much more on their own strengths when obtaining debt than on country characteristics

escape from the usa government debt to gdp ratio country tax competitiveness and us oecd cross border m as statutory tax rates of a country do not reflect a country s true tax competitiveness we propose and show that government debt to gdp ratio govdebt of a country is a better proxy for its tax competitiveness using a comprehensive sample of 1 884 completed cross border acquisition transactions from the u s to other oecd countries we document that the u s target country govdebt difference is significantly and positively related to both deal announcement return and post deal tax saving of the acquirer the govdebt difference is also significantly and positively related to u s target country deal flow the findings remain robust when we control for the potential endogeneity of govdebt difference our findings strongly suggest that tax avoidance is an important driver of u s oecd cross border deal flow and it increases shareholder wealth for u s acquirers

active vs passive decisions and crowd out in retirement savings accounts evidence from denmark using 41 million observations on savings for the population of denmark we show that the effects of retirement savings policies on wealth accumulation depend on whether they change savings rates by active or passive choice subsidies for retirement accounts which rely on individuals to take an action to raise savings primarily induce individuals to shift assets from taxable accounts to retirement accounts we estimate that each 1 of government expenditure on subsidies increases total saving by only 1 cent in contrast policies that raise retirement contributions if individuals take no action such as automatic employer contributions to retirement accounts increase wealth accumulation substantially we estimate that approximately 15 of individuals are active savers who respond to tax subsidies primarily by shifting assets across accounts 85 of individuals are passive savers who are unresponsive to subsidies but are instead heavily influenced by automatic contributions made on their behalf active savers tend to be wealthier and more financially sophisticated we conclude that automatic contributions are more effective at increasing savings rates than subsidies for three reasons i subsidies induce relatively few individuals to respond ii they generate substantial crowd out conditional on response and iii they do not increase the savings of passive individuals who are least prepared for retirement jel codes h2 h3

optimum taxation with errors in administration abstract the paper compares the welfare levels which can be achieved by two distinct tax regimes lump sum taxation where one attempts to identify individuals and allocate transfers or subsidies on the basis of characteristics and income taxation where characteristics are not observed but personal incomes are measured and taxed where there are no errors in classifying individuals lump sum taxation is superior but where mistakes are made in the allocation of lump sum grants or subsidies income taxation may be more attractive the level of errors where the regimes are equally desirable in terms of social welfare is computed in simple models following that of feldstein 1973 where there is strong aversion to inequality then income taxation becomes preferable at quite small errors in analysing income taxation it is shown that in the feldstein model with endogenous wages the marginal tax rate in optimum income taxation on the more skilled is negative and that on the less skilled is positive in contrast to the standard results see seade 1977 with exogenous wages

optimal redistributive taxation when government s and agents preferences differ abstract paternalism merit goods and specific egalitarianism are concepts we sometimes meet in the literature the thing in common is that the policy maker does not fully respect the consumer sovereignty principle and designs policies according to some other criterion than individuals preferences using the self selection approach to tax problems developed by stiglitz stiglitz j e 1982 self selection and pareto efficient taxation journal of public economics 17 213 240 and stern stern n h 1982 optimum taxation with errors in administration journal of public economics 17 181 211 the paper provides a characterization of the properties of an optimal redistributive mixed tax scheme in the general case when the government evaluates individuals well being using a different utility function than the one maximized by private agents

generalized social marginal welfare weights for optimal tax theory this paper proposes to evaluate tax reforms by aggregating money metric losses and gains of different individuals using generalized social marginal welfare weights optimum tax formulas take the same form as standard welfarist tax formulas by simply substitut ing standard marginal social welfare weights with those generalized weights weights directly capture society s concerns for fairness without being necessarily tied to individual utilities suitable weights can help reconcile discrepancies between the welfarist approach and actual tax practice as well as unify in an operational way the most prominent alternatives to utilitarianism such as libertarianism equality of opportunity or poverty alleviation jel d60 d63 h21 h23 i38

self selection and pareto efficient taxation abstract this paper analyses the set of pareto efficient tax structures the formulation of the problem as one of self selection not only shows more clearly the similarity between this problem and a number of other problems such as the optimal pricing of a monopolist which have recently been the subject of extensive research but also allows the derivation of a number of new results we establish i under fairly weak conditions randomization of tax structures is desirable ii if different individuals are not perfect substitutes for one another in production then the general equilibrium effects until now largely ignored in the literature of changes in the tax structure may be dominant in determining the optimal tax structure in particular if the relative wage of high ability and low ability individuals depends on the relative supplies of labor the optimal tax structure entails a negative marginal tax rate on the high ability individuals and a positive marginal tax rate on the low ability individuals the marnitude of which depends on the elasticity of substitution iii if individuals differ in their preferences pareto efficient taxation may entail negative marginal tax rates for high incomes while iv if wage income is stochastic the marginal tax rate at the upper end may be 100 our analysis thus makes clear that the main qualitative properties of the optimal tax structure to which earlier studies called attention are not robust to these attempts to make the theory more realistic
