policy equilibria in a federal system the effects of higher tax ceilings for unemployment insurance abstract in many federal systems a higher authority imposes changes that may alter lower level policies depending on the type of change and differences among lower level parties for example we model changes in the parameters of american states unemployment insurance ui systems when the federal government raises the ui tax ceiling bargaining among interested parties alters ui benefits and taxes we estimate a difference in differences model describing ui tax payments when federal increases in 1972 1978 and 1983 increased some states ceilings where the federal constraint was binding taxes rose nearly 20 percent the theory and empirical analysis suggest themselves as examples for future research on topics in public finance labor economics and international trade

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

widows waiting to wed re marriage and economic incentives in social security widow benefits in this paper we focus on an age restriction for remarriage in the social security system to determine if individuals respond to economic incentives for marriage aged widow er benefits are paid by the federal government to persons whose deceased spouses worked in social security covered employment a widow er is eligible to receive benefits if she or he is at least age 60 if a widow er remarries before age 60 he or she forfeits the benefit and therefore faces a marriage penalty under current law there is no penalty if the remarriage occurs at 60 years of age or later we investigate whether this rule affects the marriage behavior of widows specifically we examine the rates of remarriage of women around age 60 under current as well as past social security eligibility rules using data from the vital statistics our results provide compelling evidence that this group of women respond to economic incentives when considering the decision to remarry first the 1979 law change that eliminated the marriage penalty for those at least age 60 resulted in a large increase in the marriage rate for widows at

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

joint coherence in games of incomplete information decisions are often made under conditions of uncertainty about the actions of supposedly rational competitors the modeling of optimal behavior under such conditions is the subject of noncooperative game theory of which a cornerstone is harsanyi s formulation of games of incomplete information in an incomplete information game uncertainty may surround the attributes as well as the strategic intentions of opposing players harsanyi develops the concept of a bayesian equilibrium which is a nash equilibrium of a game in which the players reciprocal beliefs about each others attributes are consistent with a common prior distribution as though they had been jointly drawn at random from populations with commonly known proportions of types the relation of such game theoretic solution concepts to subjective probability theory and nonstrategic decision analysis has been controversial as reflected in critiques by kadane and larkey and responses from harsanyi shubik and others which have appeared in this journal this paper shows that the bayesian equilibrium concept and common prior assumption can be reconciled with a subjective view of probability by i supposing that players elicit each others probabilities and utilities through the acceptance of gambles and ii invoking a multi agent extension of de finetti s axiom of coherence no arbitrage opportunities a k a dutch books however the nash property of statistical independence between players is weakened and the probability distributions characterizing a solution of the game admit novel interpretations

the bayesian foundations of solution concepts of games abstract we transform a noncooperative game into a bayesian decision problem for each player where the uncertainty faced by a player is the strategy choices of the other players the priors of other players on the choice of other players the priors over priors and so on we provide a complete characterization between the extent of knowledge about the rationality of players and their ability to successively eliminate strategies which are not best responses this paper therefore provides the informational foundations of iteratively undominated strategies and rationalizable strategic behavior b d bernheim econometrica 52 1984 1007 1028 d pearce econometrica 52 1984 1029 1050 sufficient conditions are also found for nash equilibrium behavior and a result akin to r j aumann econometrica 55 1987 1 18 on correlated equilibria is derived with different hypotheses

correlated equilibrium as an expression of bayesian rationality if it is common knowledge that the players in a game are bayesian utility maximizers who treat uncertainty about other players actions like any other uncertainty then the outcome is necessarily a correlated equilibrium random strategies appear as an expression of each player s uncertainty about what the others will do not as the result of willful randomization use is made of the common prior assumption according to which differences in probability assessments by different individuals are due to the different information that they have where information may be interpreted broadly to include experience upbringing and genetic makeup copyright 1987 by the econometric society

rationalizable strategic behavior the notion of equilibrium proposed by nash 19 has come to play a dominant role in economic applications of noncooperative games while analyses of nash equilibria have unquestionably contributed to our understanding of economic behavior it would be unreasonably optimistic to maintain that nash solved the problem of noncooperative strategic choice there is a small literature beginning with ellsberg 6 and a much larger oral tradition which argues that nash behavior is neither a necessary consequence of rationality nor a reasonable empirical proposition in this paper i take the view that although there may be various reasons why an agent might select a nash strategy the notion of an equilibrium has little intrinsic appeal within a strategic context when an agent reaches a decision in ignorance of the strategies adopted by other players rationality consists of making a choice which is justifiable by an internally consistent system of beliefs rather than one which is optimal post hoc this point of view is not original indeed most serious justifications of the nash hypothesis embrace such an approach arguing that agents will expect the game to yield a nash outcome and consequently will choose their equilibrium strategies nevertheless when we think in terms of maximizing utility subject to expectations rather than realizations it becomes clear that the nash hypothesis far from being a consequence of rationality arises from certain restrictions on agents expectations which may or may not be plausible depending upon the game being played we are then quite naturally led to ask are there any restrictions of individuals expectations and hence choices which are required by rationality alone rather than by subjective plausibility this paper is concerned with defining justifying characterizing and refining a criterion for rational strategic choice which i label rationalizability

coherence and the credibility of convertibility announcements abstract the recent devaluation crisis in mexico and its tequila effect elsewhere illustrate that two credibility problems associated with convertibility policies currency boards are announcements that violate truth telling and a non zero probability of policy failure we derive the trade off between these problems when announcements resemble cheap talk the strategic uncertainty created by this trade off implies that both the government and investors should recognize the presence of fed watchers who exploit any policy inconsistency for their own gain in this context credibility can be restored if the policy is coherent if it eliminates the marginal benefits for fed watching jel e63 e58 f40 1997 published by elsevier science ltd

do taxes matter the impact of the tax reform act of 1986 do taxes matter is the first systematic examination of the actual effects of the tax reform act of 1986 the most important u s income tax reform of the last four decades it presents basic information on and an analysis of a variety of different aspects of economic behavior in order to discover whether the observed changes coincide with the predictions of standard public finance models prior to implementation of the new law supporters and opponents made numerous forecasts about its effect on savings corporate investment and other major determinants of the country s economic health the general finding of these original contributions is that the effects of tax reform turned out to be smaller than had been anticipated commissioned by the office of tax policy research of the university of michigan eight of the studies focus on different sectors of the economy reviewing the predictions and carefully analyzing the evidence to determine actual effects the ninth study draws together the results to find lessons for future changes in tax policy joel slemrod is professor of business economics and public policy and director of the office of tax policy research at the university of michigan contents the economic impact of tax reform act of 1986 joel slemrod investment tax policy and the tax reform act of 1986 alan j auerbach kevin hassett the impact of the 1986 tax reform on personal saving jonathan skinner daniel feenberg effects of the tax reform act of 1986 on corporate financial policy and organizational form roger h gordon jeffrey k mackie mason taxation and housing markets preliminary evidence on the effects of recent tax reforms james m poterba the impact of the tax reform act of 1986 on foreign direct investment to and from the united states joel slemrod the impact of tax reform on charitable giving a 1989 perspective charles t clotfelter the impact of the tax reform act of 1986 on state and local fiscal behavior paul n courant edward m gramlich foreign responses to u s tax reform john whalley lessons for tax reform henry j aaron

note subjective probability and the theory of games some further comments this note reconsiders some of the issues raised by kadane and larkey and harsanyi and briefly discusses some relevant empirical results

housing taxation and capital accumulation this paper studies the impact of the preferential tax treatment of housing capital in a dynamic general equilibrium life cycle economy populated by heterogeneous individuals the model includes the main housing tax provisions currently in place in the u s and a minimum downpayment requirement upon purchasing non divisible houses the tax code makes the return on housing capital larger than that on business capital which distorts the lifetime profile and composition of individuals savings the wedge between the two rates of return emanates from the failure to tax imputed rents and is amplified by the presence of mortgage interest deductibility simulations show that individuals at all income levels would rather live in a world where imputed rents are taxed or one where mortgage interest payments are not deductible furthermore distributional effects are much smaller than conventionally believed

geographic income shifting by multinational corporations in response to tax rate changes we investigate geographic income shifting by 191 u s multinational corporations in response to worldwide changes in tax rates during 1984 90 between 1984 and 1986 the united kingdom reduced corporate tax rates from a maximum of 45 to 35 and in 1985 france reduced rates from 50 to 45 following these reductions in european rates the united states reduced top corporate tax rates from 46 to 34 between 1986 and 1988 canadian rates increased between 1984 and 1986 and then decreased through 1989 beginning in 1988 numerous countries enacted tax cuts apparently in response to those that occurred earlier in other countries as discussed in section 3 differential changes in tax rates provide incentives for geographic income shifting by multinational firms we identify two subperiods during 1984 90 in which relative tax rate changes

rationalizable strategic behavior and the problem of perfection this paper explores the fundamental problem of what can be inferred about the outcome of a noncooperative game from the rationality of the players and from the information they possess the answer is summarized in a solution concept called rationalizability strategy profiles that are rationalizable are not always nash equilibria conversely the information in an extensive form game often allows certain unreasonable nash equilibria to be excluded from the set of rationalizable profiles a stronger form of rationalizability is appropriate if players are known to be not merely rational but also cautious what constitutes rational behavior in a noncooperative strategic situation this paper explores the issue in the context of a wide class of finite noncooperative games in extensive form the traditional answer relies heavily upon the idea of nash equilibrium nash 17 the position developed here however is that as a criterion for judging a profile of strategies to be reasonable choices for players in a game the nash equilibrium property is neither necessary nor sufficient some nash equilibria are intuitively unreasonable and not all reasonable strategy profiles are nash equilibria the fact that a nash equilibrium can be intuitively unattractive is well known the equilibrium may be imperfect introduced into the literature by selten 20 the idea of imperfect equilibria has prompted game theorists to search for a narrower definition of equilibrium while this research some of which will be discussed here has been extremely instructive it remains inconclusive theorists often agree about what should happen in particular games but to capture this intuition in a general solution concept has proved to be very difficult if this paper is successful it should make some progress in that direction the other side of the coin has received less scrutiny can all non nash profiles really be excluded on logical grounds i believe not the standard justifications for considering only nash profiles are circular in nature or make gratuitous assumptions about players decision criteria or beliefs the following discussion of these points is extremely brief due to space constraints more detailed arguments may be found in pearce 18

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

negotiation analysis a characterization and review negotiation analysis seeks to develop prescriptive theory and useful advice for negotiators and third parties it generally emphasizes the parties underlying interests as distinct from the issues on the table and the positions taken alternatives to negotiated agreement approaches to productively manage the inherent tension between competitive actions to claim value individually and cooperative ones to create value jointly as well as efforts to change perceptions of the game itself since advice to one side does not necessarily presume the full game theoretic rationality of the other side s negotiation analysts often draw on the findings of behavioral decision analysts and economists further this approach does not generally assume that all the elements of the game are common knowledge thus the negotiation analytic approach tends to de emphasize the application of game theoretic solution concepts or efforts to find unique equilibrium outcomes instead to evaluate possible strategies and

do people respond to tax incentives an analysis of the italian reform of the deductibility of home mortgage interests abstract before 1992 mortgage interests in italy were fully tax deductible up to 3500 euro 7000 for two cosigners in 1992 1994 the government implemented a series of tax reforms whose ultimate effect was to eliminate the relation between the after tax mortgage rate and the marginal tax rate using data from the 1989 2002 survey of household income and wealth we test if the elimination of incentives has affected the sensitivity of the decision to borrow and the amount borrowed with respect to the marginal tax rate regression analysis and difference in differences estimates indicate that tax considerations have not affected the demand for mortgage debt neither at the extensive nor intensive margin these results are consistent with lack of financial information and credit rationing during the sample period

host country reforms and fdi inflows how much difference do they make summary this study examines the effects of various policies on foreign direct investment fdi flows from the perspective of the eclectic theory of international investment and hence the advantages of foreign ownership host country location and internationalization host country policies can influence fdi flows primarily through their influence on the advantages of location in the host country pooled cross section and time series data for 49 less developed countries ldcs over 1970 95 are used to examine the effects of several different types of policy institutional variables including corporate tax rates tariff rates the degree of openness to international capital flows exchange rate distortions contract enforcement nationalization risk bureaucratic delay and corruption a multivariate analysis of the effects on fdi flows of each type of policy with and without controls for other relevant determinants is conducted two different sources of fdi data are employed as well as two different measures of capital controls although there are methodological problems in estimation and especially collinearity problems and relatively severe availability constraints for some of the relevant measures the results demonstrate the relevance and importance for fdi flows of many of the policy institutional variables under study they also indicate that the results from panel methods yield results that differ rather significantly from those obtained from pure cross section analysis because of complementarity between the various elements of a healthy investment climate the effects of some policy reforms estimated from models which do not control for changes in other policies may overstate the effectiveness of individual policy reforms

the value of energy efficiency and the role of expected heating costs the german energy performance of buildings directive requires sellers on the housing market to provide detailed information on expected yearly energy consumption per square meter energy performance eps this paper uses variation in local fuel prices and climate fuel types and building ages to analyse the relationship between expected energy cost savings from energy efficient building structure and house prices in a data set of listing prices from all regions of germany results suggest that heating cost considerations are less relevant than previously thought

an evaluation of alternative measures of corporate tax rates abstract this paper examines the ability of financial statement measures of average and marginal tax rates mtr to capture tax attributes utilizing firm level tax and financial data the results suggest commonly used average tax rate measures provide little insight about statutory tax burdens and may introduce substantial bias into analyses of tax incidence financial statement based proxies for mtr particularly those based on simulation methods are found to perform well in estimating current year tax rates both current year and present value mtr are found to be highly correlated with an easily constructed binary proxy of firms tax status

note on choosing between rev bayes and prof von neumann in a recent issue of management science kadane and larkey 10 11 debated with harsanyi 8 9 on the relative merits of strategic policies derived from game theoretic vs bayesian decision theoretic orientations while the fact that the two orientations are virtually first cousins gives a middle eastern flavor to the discussion just as the problems of that unfortunate spot on the globe the two orientations have substantive differences that should be attended to by people faced with managerial decision problems modelled as games

the impact of state taxes on self insurance abstract this paper assesses whether insurers state taxes reduce purchases of property casualty coverage tests are conducted using state aggregates of insurer level data from publicly available annual accounting reports for 1993 1995 a positive relation between self insurance and state taxes is detected consistent with consumers opting to self insure rather than bear the incidence of higher insurer taxes as expected tax effects vary with the elasticity of demand when demand is largely inelastic e g automobile liability coverage taxes do not affect self insurance
