reforming taxes and raising revenue part of the fiscal solution this paper reviews the fiscal outlook in the united states discusses why revenue increases are a critical aspect of any enduring fiscal solution and outlines constructive policies to reform the tax system and simultaneously raise revenues in particular this paper highlights the merits of curtailing income tax expenditures introducing a value added tax and imposing levies on consumption and production of non renewable energy copyright 2011 oxford university press

wealth distribution in life cycle economies abstract this paper compares the age wealth distribution produced in life cycle economies to the corresponding distribution in the us economy the idea is to calibrate the model economies to match features of the us earnings distribution and then examine the wealth distribution implications of the model economies the findings are that the calibrated model economies with earnings and lifetime uncertainty can replicate measures of both aggregate wealth and transfer wealth in the us furthermore the model economies produce the us wealth gini and a significant fraction of the wealth inequality within age groups however the model economies produce less than half the fraction of wealth held by the top 1 percent of us households

valuing lost home production of dual earner couples using a life cycle model in which women divide their time between home and market work we establish a link between retirement wealth and the value of forgone home production we use data from the health and retirement study to estimate the model s parameters and adjust the growth rate of gdp to reflect reductions in non market output we find that the value of forgone home production is modest about 25 percent of women s measured earnings

financial contracting under extreme uncertainty an analysis of brazilian corporate debentures abstract economic volatility high transaction costs and fragile institutions hinder financial contracting in emerging markets these conditions characterize the economy of brazil yet a nascent corporate bond market thrives i analyze 50 brazilian indenture agreements and find that sample debentures are characterized by i features that mitigate inflation risk for investors ii contingent maturity mechanisms that provide periodic opportunities for exit or renegotiation iii a paucity of covenants that restrict the debtor s investment financing and dividend decisions and iv self enforcement mechanisms that avoid reliance on inefficient institutions analysis of these features enhances our understanding of contracting in emerging economies

unfunded liabilities and uncertain fiscal financing we develop a rational expectations framework to study the consequences of alternative means to resolve the unfunded liabilities problem the projected exponential growth in federal social security medicare and medicaid spending with no known plan for financing the transfers resolution requires specifying a probability distribution for how and when monetary and fiscal policies will change as the economy evolves through the 21st century beliefs based on that distribution determine the existence of and the nature of equilibrium we consider policies that in expectation combine reaching a fiscal limit some distorting taxation modest inflation and some reneging on the government s promised transfers in the equilibrium inflation targeting monetary policy and debt targeting tax policy cannot anchor expectations on those target variables expectational effects are always present but need not have large impacts on inflation and interest rates in the short and medium runs in the economy s stationary distribution the capital stock may grow or shrink and substantial probability falls on little or no reneging

fiscal policy composition of intergenerational transfers and income distribution abstract in this paper we characterize the relationship between the initial distribution of human capital and physical inheritances among individuals and the long run distribution of these two variables in a model with indivisible investment in education we analyze how the initial distribution of income determines the posterior intergenerational mobility in human capital and the evolution of intragenerational income inequality this analysis enables us in turn to characterize the effects of fiscal policy on future income distribution and mobility when the composition of intergenerational transfers is endogenous to this end we consider the following government interventions a pay as you go social security system a tax on inheritance a tax on capital income a tax on labor income and a subsidy on education investment

crowding out voluntary contributions to public goods we test the null hypothesis that involuntary transfers for the provision of a public good will completely crowd out voluntary transfers against the warm glow hypothesis that crowding out will be incomplete because individuals care about giving our design differs from the related design used by andreoni in considering two levels of the involuntary transfer and a wider range of contribution possibilities and in mixing groups every period instead of every four periods we analyse the data with careful attention to boundary effects we retain the null hypothesis of complete crowding out in two of three pairwise comparisions but reject it in favour of incomplete crowding out in the comparison most closely akin to andreoni s design thus we confirm the existence of incomplete crowding out in some environments but suggest that the warm glow hypothesis is inadequate in explaining it

an empirical model of labor supply in a life cycle setting this paper formulates and estimates a structural intertemporal model of labor supply using theoretical characterizations derived from an economic model of lifetime behavior a two step empirical analysis yields estimates of intertemporal and uncompensated substitution effects which provide the information needed to predict the response of hours of work to life cycle wage growth and shifts in the lifetime wage path

gradual tax reforms if you like it you can keep it abstract one of the key practical challenges facing by tax reforms are their short run welfare consequences in this paper i focus on a consumption based tax reform for which despite long run welfare gains it generates welfare for some groups such as retirees or the working poor falls during transition between steady states using a life cycle model with heterogeneous households i show how to devise a transition path from the current u s federal tax system to a consumption based tax system that improves the welfare of current as well as future generations in a nutshell all households alive at the time of the policy change can choose when they want to switch to the new tax system or whether they want to switch at all i find that implementing a tax reform with this feature improves the welfare of 95 of population in the short run compared to less than a quarter of population in the conventional case with no choice it takes about twenty years for half of the population to pay their taxes under the new tax code

taxation and household labor supply we evaluate reforms to the u s tax system in a life cycle setup with heterogeneous married and single households and with an operative extensive margin in labor supply we restrict our model with observations on gender and skill premia labor force participation of married females across skill groups children and the structure of marital sorting we concentrate on two revenue neutral tax reforms a proportional income tax and a reform in which married individuals flle taxes separately separate flling our flndings indicate that tax reforms are accompanied by large increases in labor supply that difier across demographic groups with the bulk of the increase coming from married females under a proportional income tax reform married females account for more than 50 of the changes in hours across steady states while under separate flling reform married females account for all the change in hours

tax progressivity and tax incidence of the rich and the poor with the labor supply being flexible a revenue neutral increase in the tax progressivity decreases the tax incidence of the rich and increases the tax incidence of the poor if the tax scheme is highly progressive

tax policy and the financing of innovation we study tax policy in a schumpeterian growth model with asymmetric information in the financing of innovation investors cannot a priori distinguish between more or less talented entrepreneurs net worth allows talented entrepreneurs to self invest and avoid being pooled with less talented entrepreneurs in the credit market increasing net worth boosts innovation even when financed through higher profit taxes taxing consumption effectively raises net worth and subsidizes profits simultaneously sufficiently taxing consumption implements the social optimum free of adverse selection if forced to tax consumption less the government implements a second best allocation with adverse selection when boosting net worth enough to avoid adverse selection requires taxing profits excessively

existence and uniqueness of steady state equilibrium in a two sector overlapping generations model abstract in his seminal paper galor a two sector overlapping generations model a global characterization of the dynamical system econometrica 60 1992 1351 1386 establishes conditions for the existence of equilibrium in the two sector overlapping generations olg model although appealing theoretically these conditions are implicit and not easy to apply this paper develops new theorems on the existence and uniqueness of steady state equilibrium in the two sector olg model we provide explicit conditions on the utility and production functions for the existence and uniqueness of equilibrium with which one only needs to check the derivatives of the production and utility functions and their interactions without requiring solving for the savings function and its derivatives we present detailed steps to check the existence and uniqueness of equilibrium and provide illustrative examples

marginal welfare costs of taxation with human and physical capital i introduction marginal welfare cost of taxation is the amount by which the social cost of an additional tax dollar differs from 1 because of distortionary taxation browning and johnson 1984 stuart 1984 browning 1987 ballard 1988 and allgood and snow 1998 use static models of the u s economy in which labor supplies adjust but the stocks of human and physical capital are fixed to calculate estimates of this welfare cost relevant to cost benefit analysis the studies by lucas 1990 and perroni 1995 incorporate human and physical capital into calculations of excess burden for the purpose of comparing alternative tax systems but do not address the welfare costs of marginal tax and spending reforms ballard et al 1985 and judd 1987 provide estimates of welfare cost using models that allow the stock of physical capital to change in response to marginal reforms but the stock of human capital is exogenous in these studies however judd 2001 argues that there is ample evidence indicating that human capital investment decisions have a significant effect on the cost of altering the tax system which suggests that these decisions could also have an important influence on marginal welfare cost in this article we present estimates of welfare costs for marginal reforms to government tax and spending policies when labor supply saving and education decisions are all endogenous we focus our analysis on marginal reforms because as skinner and slemrod 1985 observe most policy reforms enacted do not involve replacing one tax or spending system with another but instead typically entail marginal adjustments in tax laws and government appropriations using a perfect foresight overlapping generations model with a three period life cycle we derive analytical expressions for the changes in labor supply saving and education and use them to calculate marginal welfare cost as shown by auerbach et al 1983 in overlapping generations models steady state welfare comparisons of alternative tax policies are biased unless households are compensated for intergenerational redistribution along the transition path to arrive at our steady state estimates of welfare costs we adapt the compensation method introduced by gravelle 1991 for analyzing fundamental tax reforms to the context of incremental tax and spending reforms in a static one consumer model triest 1990 has shown that marginal welfare cost mwc is positive solely because of tax leakage the decline in tax revenue caused by reductions in the tax base we extend this insight to an intertemporal context that incorporates tax leakage arising from changes in both human and physical capital investment we evaluate three sets of reforms first a revenue neutral reduction in the tax on capital income funded by a higher tax on labor income second spending on a public good financed by either a higher tax on labor or interest income third a per capita lump sum transfer or demogrant also funded by either a higher tax on labor or interest income we find that marginal welfare costs are uniformly lower in the dynamic model where investment decisions are endogenous than in the static model where investment decisions are fixed and that the majority of the difference between the dynamic and static estimates is attributable to human capital decisions the principal reason is that a reallocation of time between labor hours and human capital investment has opposing and potentially offsetting effects on effective labor supply as a result labor supply responds less elastically in the dynamic model and changes in labor supply are the main source of tax leakage because wage taxation is the main source of tax revenue we also find that shifting marginal financing from capital to labor results in a lower welfare cost the reason being that such a change encourages saving which increases wage rates and stimulates labor supply leading to a reduction in marginal welfare costs

a strategic analysis of sinking fund bonds abstract unlike most securities the pricing of sinking fund bonds is influenced by the distribution of ownership which summarizes the extent to which the market is cornered the effect of the distribution of ownership on the pricing of sinking fund bonds is examined by an explicit game in which the price obtained for bonds sold can depend upon the size of the investor s position this framework is used to contrast the valuation of sinking fund bonds with the valuation of amortizing bonds and straight debt we show that it is generally incorrect to view sinking fund bonds as being equivalent to serial bonds

default risk yield spreads and time to maturity this paper extends the default model of yield spreads for bonds by showing that in gen eral they are a complex function of maturity and in particular are not always monotoni cally increasing contrary to what one traditional view suggests our results may help explain the apparently conflicting empirical results found in the literature

earnings test non actuarial adjustments and flexible retirement abstract in response to the challenges of increasing longevity many countries have introduced flexibility reforms for their public pension systems a key measure of these reforms is the abolishment of earnings tests it is claimed that these reforms increase labor supply and therefore the financial sustainability of pension systems we build a simulation model to show that abolishing an earnings test may indeed create more labor supply but simultaneously reduce the average claiming age when adjustments remain less than actuarial as is the case in most european pension systems flexibility reforms may therefore worsen rather than improve the sustainability of public pension systems

growth effects of flat rate taxes recent estimates of the potential growth effects of tax reform vary wildly ranging from zero to eight percentage points using an endogenous growth model we assess which model features and parameter values are important for determining the quantitative impact of tax reform we find that the critical parameters are factor shares depreciation rates the elasticity of intertemporal substitution and the elasticity of labor supply the elasticities of substitution in production on the other hand are relatively unimportant the quantitative estimates in several recent papers are compared with each other and with some of the evidence from u s experience we find that robert lucas s conclusion that tax reform would have little or no effect on the u s growth rate is theoretically robust and consistent with the evidence

endogenous life cycle housing investment and portfolio allocation this paper develops a life cycle portfolio allocation model to address the effects of housing investment on the portfolio allocation of households the model employs a comprehensive housing investment structure epstein zin recursive preferences and a stock market entry cost furthermore rather than resorting to calibration we estimate the value of the relative risk aversion and elasticity of intertemporal substitution the model shows that housing investment has a strong crowding out effect on investment in risky assets throughout the life cycle we further find that the effect of the presence of housing investment on households portfolio allocation is larger than the effect of having ez recursive preferences jel classification g0 g11 g12 d10

the choice of call provision terms evidence of the existence of agency costs of debt an examination of the provisions of bond issues reveals that most bonds prohibit firms from calling the issue during the initial years after which time the bond can be called at the option of the firm a substantial number of firms however also reserve the right to call the issue during this initial period for purposes other than refinancing at a lower coupon rate the additional flexibility which accompanies the option of early redemption can be used to reduce the agency costs of debt associated with future investment opportunities informational asymmetry and the risk incentive problem using a sample of newly issued bonds statistical tests are performed to show that there are in fact differences between firms which do and do not reserve the right of early redemption this paper shows that these differences provide empirical evidence which is consistent with the hypothesis that firms use the option of early redemption to reduce agency costs one of the decisions which a firm must make when it floats a bond issue concerns the use of a call provision if a call provision is included in the bond then the terms of the call provision must be specified such as the years to the first call the initial call price the call price in subsequent years and the circumstances under which a call provision can be used previous work in the area of call provisions focused on fluctuations in interest rates as the reason for their existence it was shown by krause 12 however that in an efficient capital market any call provision decision based on interest rate uncertainty is irrelevant recent work in agency theory has shown that the existing contractual relationships between bondholders and stockholders may not be a zero sum game under these circumstances such financing decisions as capital structure debt maturity and call provisions may not be irrelevant an examination of the call provisions of currently outstanding bond issues reveals an institutional feature which is often overlooked many bonds have a standard call provision which restricts the firm from calling the issue for a stated number of years followed by a period during which firms have the option to call the bond at a stated call price another group of bond issues however contain a two tiered type of call provision which allows the corporation to call the bond for purposes other than refinancing at a lower coupon rate during the initial years of the life of the bond after this initial period the firm has the option of calling the bond issue for any purpose

the surprising power of age dependent taxes this paper provides a new empirically driven application of the dynamic mirrleesian framework by studying a feasible and potentially powerful tax reform age dependent labour income taxation i show analytically how age dependence improves policy on both the intratemporal and intertemporal margins i use detailed numerical simulations calibrated with data from the u s panel study of income dynamics to generate robust policy implications age dependence 1 lowers marginal taxes on average and especially on high income young workers and 2 lowers average taxes on all young workers relative to older workers when private saving and borrowing are restricted finally i calculate and characterize the welfare gains from age dependence despite its simplicity age dependence generates a welfare gain equal to between 0 6 and 1 5 of aggregate annual consumption and it captures more than 60 of the gain from reform to the dynamic optimal policy the gains are due to substantial increases in both efficiency and equity when age dependence is restricted to be pareto improving the welfare gain is nearly as large

economic effects of fundamental tax reform brookings institution the tax system profoundly affects countless aspects of private behavior it is a powerful policy influence on the distribution of income and it is the one aspect of government that almost every citizen cannot avoid with tax reform high on the political agenda this book brings together studies of leading tax economists and lawyers to assess the various reform proposals and examine the effects of tax reform in several distinct areas together these studies and comments on them present a balanced evaluation of professional opinion on the issues that will be critical in the tax reform debate the book addresses annual and lifetime distributional effects saving investment transitional problems simplification home ownership and housing prices charitable groups international taxation financial intermediaries and insurance labor supply and health insurance

the effects of marital status and children on savings and portfolio choice this paper investigates the impact of demographic shocks on optimal decisions about saving life insurance and most centrally asset allocation we analyze these choices within the framework of a life cycle model that features exogenous changes in family composition heterogeneity in lifetime income and uninsurable fluctuations in earnings and medical costs our analysis indicates that marital status transitions and children can have important effects on optimal household decisions widowhood induces sharp reductions in the portfolio shares in stock and the impact is largest for women and individuals with children divorce causes men and women to reallocate their portfolios in different directions men choose much riskier allocations while women opt for safer ones children play a fundamental role in the optimal portfolio decisions men with children for example increase their shares in response to divorce by less than half as much as men without children comparing our simulation results with panel data evidence on stockholding from the psid and the hrs we conclude that changes in marital status and children matter empirically as well but not always in the ways that the model predicts

new evidence on altruism a study of tiaa cref retirees this paper investigates the role in household wealth accumulation of saving for bequests it employs data from a 1988 survey of tiaa cref annuitants designed to measure pension and other net worth as well as lifetime earnings about half of the households in the data plan to leave estates and the authors find that their behavior conforms with theoretical altruistic models for the same families the amount of wealth that the authors attribute to estate building is large nevertheless altruism towards one s children does not seem to be the major explanation of saving in the overall sample copyright 1996 by american economic association

callable bonds reinvestment risk and credit rating improvements role of the call premium we identify the call premium in nonconvertible callable bonds as an effective contracting provision to address agency conflict due to reinvestment risk and credit rating improvements we analyze 4 495 bonds issued between 1980 and 2012 when interest rates are high a majority of investment grade issues and almost the entire subset with long maturities 20 years include a call premium when interest rates are low virtually all investment grade issues with long and short maturities are callable at par high yield issues are limited to short maturities by about 4 1 they include a call premium regardless of interest rate levels

non excludable public good experiments we conduct a two stage game experiment with a non excludable public good in the first stage two subjects choose simultaneously whether or not they commit to contributing nothing to provide a pure public good in the second stage knowing the other subject s commitment decision subjects who did not commit in the first stage choose contributions to the public good we found no support for the evolutionary stable strategy equilibrium and the ratio of subjects who did not commit to contributing nothing increased as periods advanced that is the free riding rate declined over time furthermore this behavior did not arise due to altruism or kindness among subjects but from spiteful behavior of subjects

the role of intergenerational transfers and life cycle saving in the accumulation of wealth he purpose of this paper is to review what economists know at present about the following question how large a portion of the existing wealth is the result of a bequest motive that is of accumulation for the specific purpose of leaving bequests i will also endeavor to clarify why an answer to this question is of interest in the early keynesian period when the study of national saving first attracted wide interest relatively little attention was paid to what led people to save though it was generally understood that the main systematic reason was to leave bequests j m keynes in the famous chapter 9 of the general theory of employment interest and money 1936 had listed seven distinct motives for saving besides the leaving of bequests but five of these which include to increase one s future income or to insure one s independence and power implied that all or nearly all the accumulation would finally wind up as bequeathed wealth this in turn meant that most private wealth originated through bequests that is it either had been received through bequests or was destined to be bequeathed and indeed how else could society accumulate wealth however keynes 1936 p 107 also mentioned two further motives precaution that is to build up a reserve against unforeseen contingencies and foresight that is to provide for an anticipated future relation between the income and the needs of the individual or his family different from that which exists in the present as for example in relation to old age family education or the maintenance of dependents these motives in contrast to most of the previous ones have the

transfers and the weakest link an extension of hirshleifer s analysis abstract with the weakest link social composition function analysed by hirshleifer it is shown that an incentive exists for some agents to transfer resources to others so as to achieve higher quantities of the public good the characteristics of such an equilibrium with transfers are examined together with the implications of differing income distributions for the quantity of the public good some observations are offered as to how well the model can capture co operative behaviour

the effects of progressive taxation on labor supply when hours and wages are jointly determined this paper extends a standard intertemporal labor supply model to account for progressive taxation as well as the joint determination of hourly wages and hours worked we show that these two factors can have implications for both estimating labor supply elasticities as well as for using these elasticities in tax analysis failure to account for wage hours ties and progressive taxation may cause the hours response to marginal tax rate changes to be understated by 5 to 30 percent for men

the max min group contest weakest link group all pay auction we investigate a group all pay auction in which each group s effort is represented by the minimum among the effort levels exerted by the group members and the prize is a group specific public good we fully characterize the symmetric equilibria for two groups there are four types of equilibria the pure strategy equilibria in which all active players exert the same effort the semi pure strategy equilibria in which the players in a group play the same pure strategy whereas those in the other group play the same mixed strategy the nondegenerate mixed strategy equilibria with continuous support and the nondegenerate mixed strategy equilibria with discontinuous support we then analyze a general contest with n groups

social security and individual welfare precautionary saving borrowing constraints and the payroll tax this paper examines the impact of social security on national saving and individual welfare in the presence of realistic capital market imperfections market failure in the private provision of annuities and restrictions on borrowing against anticipated future wages the introduction of social security increases lifetime welfare and reduces national saving if borrowing restrictions are absent however the increase in individual welfare is reduced and in some cases eliminated when borrowing constraints are taken into consideration the substantial difference suggests the importance of reexamining the proportional payroll tax finance of social security copyright 1987 by american economic association

the relative tax benefits of alternative call features in corporate debt this paper examines the differential tax treatment of the borrower and lender at the time debt is called as a potential explanation for the widespread existence of call provisions in corporate debt this tax effect alone cannot explain the standard call feature because greater tax benefits may be derived for bonds callable at market prices the equilibrium implications of the model allowing for tax arbitrage opportunities both at the corporate level and the individual level also are considered

foreign aid and weakest link international public goods an experimental study in this paper we investigate efficiency differences between income and in kind transfers as distribution mechanisms of foreign aid to weakest link international public goods in a laboratory environment we find that if there is relatively small difference in country size then income transfers seem to provide a higher provision of the international public good and thus higher overall welfare level than that of in kind transfers however if there is a large disparity in country size then in kind transfers appear to provide a higher level of ipg provision and higher accompanying global welfare

weakest link public goods giving in kind or transferring money abstract this paper extends the analysis of weakest link public goods whose level equals the smallest of the agents provision levels by permitting an agent either to increase one s own provision or else augment both one s own provision and that of the other agent s nash equilibria may be either symmetric with agents matching one another s provision or else asymmetric with an in kind transfer by one agent to another an equilibrium with cash transfers but no in kind transfers may be pareto superior to one with only in kind transfers if agents differ in their efficiency then in kind transfers by the low cost agent may dominate a cash transfer the possibility of pareto improving transfers is enhanced as the number of agents increases

marginal tax rates and income inequality in a life cycle model in this paper we perform computational counterfactual experiments to examine the quantitative impact of marginal tax rates on the distribution of income our methodology builds on previous simulation models developed by auerbach and kotlikoff and fullerton and rogers and uses an algorithm that allows us to examine marginal tax rate structures in their literal form we find that distortions associated with particular marginal tax rate structures have sizable effects on income inequality in a reasonably quantified life cycle setting in our baseline experiments the change in steady state income inequality under 1989 u s income tax rates vis a vis 1984 rates is about half as large as the change actually seen in the data over those two years when measured in terms of a monetary metric derived from gini coefficients

deadweight costs and the size of government abstract we provide a model for analyzing effects of the tax system and spending programs on the determination of government spending and taxpayer welfare an improvement in the efficiency of either taxes or spending would reduce political pressure for suppressing the growth of government and thereby increase total tax revenue and spending we demonstrate the similarity of the political responses to revenue shocks spending shocks changes in tax efficiency and changes in spending program efficiency empirical analysis of oil shocks intergovernmental grants and other autonomous changes in taxes or spending indicates that cause and effect is not only from spending to tax structures

debt financing under asymmetric information the authors analyze the optimal design of debt maturity coupon payments and dividend payout restrictions under asymmetric information they show that if the asymmetry of information is concentrated around long term cash flows firms finance with coupon bearing long term debt that partially restricts dividend payments if the asymmetry of information is concentrated around near term cash flows and there exists considerable refinancing risk firms finance with coupon bearing long term debt that does not restrict dividend payments finally if the asymmetry of information is uniformly distributed across dates firms finance with short term debt

the determinants of the maturity of corporate debt issues we document the determinants of the term to maturity of 7 369 bonds and notes issued between 1982 and 1993 our main finding is that large firms with investment grade credit ratings typically borrow at the short end and at the long end and of the maturity spectrum while firms with speculative grade credit ratings typically borrow in the middle of the maturity spectrum this pattern is consistent with the theory that risky firms do not issue short term debt in order to avoid inefficient liquidation but are screened out of the long term debt market because of the prospect of risky asset substitution traditionally capital structure research has focused on how much of a firm s future cash flows should be paid out to debtholders instead of equityholders an equally important issue is when future cash flows should be paid out to debtholders a firm that finances its projects with short term debt risks serious financial difficulty if the debt cannot be extended similarly a firm that finances its activities with long term debt can sacrifice profits by needlessly risking mismanagement of resources after cash flows are returned from investments but before they are due to debtholders this study investigates the factors that firms consider when choosing the maturity of their liabilities we document the determinants of the maturity of 7 368 public debt issues made by u s corporations between 1982 and 1993 our empirical tests are based on existing theoretical models that relate the maturity of a firm s borrowings to the riskiness of its cash flows the time until investments pay off the quality of information held by outsiders the expected

simulating the transmission of wealth inequality via bequests abstract this paper develops calibrates and simulates a dynamic 88 period olg model to study the intergenerational transmission of u s wealth inequality via bequests the model features marriage realistic fertility patterns random death assortative mating based on skills heterogeneous skill endowments heterogeneous rates of return skill inheritability progressive income taxation and resource annuitization via social security all bequests arise from imperfect annuitization nonetheless the model generates a realistic ratio of aggregate wealth to aggregate labor income a realistic bequest flow relative to the stock of wealth and a realistic wealth distribution at retirement skill differences assortative mating social security and the time preference are the primary determinants of wealth inequality bequests do propagate wealth inequality but only in the presence of social security which disproportionately disinherits the lifetime poor intergenerational wealth immobility also considered here is primarily determined by the inheritance of skills from one s parents and the magnification of the impact of this inheritance by marital sorting

the optimality of call provision terms there is substantial variation in fixed price call provision terms call price premium and call protection i investigate determinants of call price call protection and estimated call option value

the role of intergenerational transfers in aggregate capital accumulation this paper uses historical u s data to directly estimate the contribution of intergenerational transfers to aggregate capital accumulation the evidence presented indicates that intergenerational transfers account for the vast majority of aggregate u s capital formation only a negligible fraction of actual capital accumulation can be traced to life cycle or hump savings a major difference between this study and previous investigations of this issue is the use of more accurate longitudinal age earnings and age consumption profiles these profiles are simply too flat to generate substantial life cycle savings this paper suggests the importance of and need for substantially greater research and data collection on intergenerational transfers life cycle models of savings that emphasize savings for retirement as the dominant form of capital accumulation should give way to models that illuminate the determinants of intergenerational transfers

social security reform and intertemporal smoothing abstract this paper examines the welfare and distributional impact of switching from a defined benefit pension system like social security to a defined contribution system of personal retirement accounts pras while such a switch would do away with the transfers that low wage workers receive through social security it would have the benefit of reducing labor supply distortions moreover a particular kind of pra suggested in this paper one that has very low or zero contribution rates early in life substantially enhances life cycle patterns of consumption and labor supply by making more resources available to credit constrained young workers simulations of a life cycle model show that in welfare terms these pras significantly outperform conventional pras because of this enhanced intertemporal smoothing

wealth inequality and altruistic bequests this paper examines the role of bequests and inter vivos gifts in the u s economy considering their importance in determining i the economy s aggregate capital stock ii the distribution of private net worth and iii public policy outcomes and options it focuses on several recent calibrated simulations this abstract was borrowed from another version of this item

intergenerational policy and the measurement of tax incidence we evaluate the ability of generational accounting to assess the potential welfare implications of policy reforms in an intergenerational context policy reforms usually have redistributive efficiency and general equilibrium implications our analysis shows that when the policy reform implies changes in economic efficiency generational accounts can be misleading not only about the magnitude of welfare changes but also about the identity of who wins and who losses in contrast the generational accounts correctly identify welfare changes when the policy reform has only a pure intergenerational redistribution component we illustrate and quantify this issue in the context of widely considered policy reforms substitution of consumption for labor taxation and the increase of retirement age and in a more general context of optimal policy

simulating fundamental tax reform in the united states this paper uses a new large scale dynamic life cycle simulation model to compare the welfare and macroeconomic effects of transitions to five fundamental alternatives to the u s federal income tax including a proportional consumption tax and a flat tax the model incorporates intragenerational heterogeneity and a detailed specification of alternative tax systems simulation results project significant long run increases in output for some reforms for other reforms namely those that seek to insulate the poor and initial older generations from adverse welfare changes long run output gains are modest

altruism incomplete markets and tax reform abstract we compute the welfare effects of different revenue neutral tax reforms that eliminate capital income taxation in two general equilibrium models calibrated to the u s economy in our dynastic model the reform with the largest welfare gain is the one that eliminates all income taxation and increases the consumption tax to 35 75 of the population alive at the time of the reform benefit from it individuals use intervivos transfers and bequests to redistribute the long run benefits in a pure life cycle economy that lacks this redistribution technology we find that the same reform would benefit only 9 of the population

on the relevance of debt maturity structure in this paper we present a tax induced framework to analyze debt maturity problems we show that under some modifications of the existing u s tax code debt maturity is irrelevant even in the presence of taxes and bankruptcy costs that yield an optimal capital structure if this restrictive structure is relaxed and assuming the miller 15 equilibrium does not prevail tax reasons would usually imply the existence of an optimal debt maturity structure if there exists a gain from leverage then an increasing term structure of interest rates adjusted for default risk results in long term debt being optimal a decreasing term structure under similar circumstances renders short term debt optimal in the absence of agency costs a miller 15 type result emerges at equilibrium and irrelevance prevails we also argue that agency costs could again reverse the irrelevance and imply a firm specific optimal debt maturity structure there has been extensive discussion in the literature concerning the existence of an optimal debt maturity structure kraus 13 states without proof that efficient capital markets preclude the existence of an optimal debt maturity stiglitz 20 demonstrates the irrelevance of debt maturity but in an economic environment in which the entire financing decision is irrelevant due to the absence of taxes and bankruptcy costs in contrast morris 16 argues that the issuance of short term debt can reduce the risk to stockholders and thereby increase equity value if the covariance between the net operating income and future interest rates is positive this result by morris is obtained even in the absence of taxes and when there is no probability of default the discrepancy between morris and stiglitz arises because morris uses the bogue and roll 31 multiperiod capital asset pricing model to incorporate uncertain future interest rates which implicitly assumes that investors cannot diversify away intertem

tax reform and adjustment costs the impact on investment and market value this paper provides an effective tax rate measure that is valid in the presence of adjustment costs and anticipated tax changes and a measure of the impact of tax changes on market value that may be decomposed into the effects on discounted pure profits and normal returns to capital changes in the value of capital may in turn be decomposed further into changes in the marginal value of new capital and changes in the relative value of new and existing capital these new measures are used to evaluate tax changes similar to those introduced by the recent u s tax reform copyright 1989 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

consumption retirement and social security evaluating the efficiency of reform that encourages longer careers abstract this paper proposes and analyzes a social security reform in which individuals no longer face the oasi payroll tax after say age 54 or a career of 34 years and their subsequent earnings have no bearing on their benefits we first estimate parameters of a life cycle model our specification includes non separable preferences and possible disability it predicts a consumption expenditure change at retirement we use the magnitude of the expenditure change together with households retirement age decisions to identify key structural parameters the estimated magnitude of the change in consumption expenditure depends importantly on the treatment of consumption by adult children of the household simulations indicate that the reform could increase retirement ages one year or more equivalent variations could average more than 4000 per household and income tax revenues per household could increase by more than 14 000

parental altruism and inter vivos transfers theory and evidence this paper uses psid data on the extended family to test whether inter vivos transfers from parents to children are motivated by altruism specifically the paper tests whether an increase by one dollar in the income of parents actively making transfers to a child coupled with a one dollar reduction in that child s income results in the parents increasing their transfer to the child by one dollar this restriction on parental and child transfer income derivatives is derived for the standard altruism model augmented to include uncertainty and liquidity constraints these additional elements pin down the timing of inter vivos transfers the method used to estimate income transfer derivatives takes into account unobserved heterogeneity across families in the degree of altruism the findings strongly reject the altruism hypothesis redistributing one dollar from a recipient child to donor parents leads to less than a 13 cent increase in the parents transfer to the child far less than the one dollar increas

task divisions in teams with complementary tasks abstract a team leader and a team follower non cooperatively produce a team specific public good out of two complementary tasks both team members are identically productive and can contribute to both tasks by moving first the team leader effectively determines the division of the tasks in the team we show that the existence of multiple but finitely many types of task divisions is associated with a non convex leader s budget constraint non convexity generates discontinuities and non monotonicities in the equilibrium provision of the good and also in the follower s utility if incomes are redistributed within the team non monotonicity of the follower s utility motivates the follower to give a cash transfer to the leader having received the cash transfer the leader adopts a task division that compensates the contributions of the follower hence we observe a non cooperative gift exchange with a monetary gift to the leader and a subsequent non monetary reward to the follower through a lighter task allocation these gift exchanges disappear in the presence of infinitely many types of task divisions generated by a continuum of complementary tasks

the retirement savings puzzle reviewed the role of housing and bequests the so called retirement savings puzzle is a phenomenon by which contrary to what the standard life cycle model predicts households do not run down their wealth significantly during retirement in this review paper we survey the literature on the retirement savings puzzle and we connect it with the literature on housing equity during retirement to establish a link between these two streams of literature we use as a framework the work of nakajima and telyukova 2013a home equity in retirement ucsd working paper and nakajima and telyukova 2017 reverse mortgage loans a quantitative analysis journal of finance 72 911 950 who find that home ownership interacts with factors that explain the retirement savings puzzle notably with the bequest motive we complement the results by nakajima and telyukova by relating them to the literature on altruistic bequests strategic bequests and housing as a commitment device all of which give further insights on the connection between home ownership and bequests we complement our review of the literature with descriptive evidence using the netherlands as a case study

the call sinking fund and term to maturity features of corporate bonds an empirical investigation do bond issuing firms attempt to choose the call sinking fund and term to maturity features of bonds to improve shareholder wealth this paper develops and tests two hypotheses about the determinants of bond features using a conditional logistic model the model is estimated on a sample of bonds issued between 1982 and 1986 model estimates show that a bond s call sinking fund and term to maturity features are statistically related to the issuing firm s retention ratio ratio of convertible to long term debt two year change in net operating income and whether the firm is listed on the nyse and included in the s p400 these findings support the view that firms financing highquality projects but facing information asymmetries choose shorter term medium term callable bonds with and without the sinking fund feature

flattening of bond yield curves for long maturities the paper presents a theoretical proof that flattening of yield curves for par bonds is inevitable for long maturities this proof implies that behavioral explanations of flattening are unnecessary the proof also implies that the use of yields to maturity of couponbearing bonds to estimate the true term structure as well as forward rates for long maturities has potentially infinite bias suggesting that a greater effort should be made to directly estimate the true term structure in empirical work empirically observed bond yield to maturity curves have consistently been found to become flat for long maturities as evidenced by the empirical work of durand 6 7 8 malkiel 15 and the treasury bulletin 25 a concise summary of this evidence is contained in malkiel 15 he presents three dimensional graphs of corporate bond yield curves from 1900 to 1965 15 pp 8 9 and two dimensional graphs of yield curves for u s government securities for the period 1953 66 15 p 13 both of these show that flattening of yield curves occurs consistently for long maturities more recent u s government bond yield curves in the treasury bulletin exhibit a similar flatness for long maturities malkiel 15 considered flattening of yield curves for long maturities to be an important desiderata that a theory of the term structure must fulfil he said that a term structure theory must account for the pervasive tendency of the yield curve to level out as term to maturity increases and to develop what is called a shoulder irrespective of the general shape in the early maturities slopes with large absolute values occur only in the early maturities 15 p 16 malkiel has suggested that the shape of yield curves depends on the sensitivity of bond price to changes in interest rates according to malkiel s viewpoint if long term bonds of different maturities have essentially the same price sensitivity to interest rate changes yield curves would tend to be flat for long maturities in another viewpoint lutz 14 has said that the flattening of yield curves is the result of constant long term forward rates for long maturities this view would be justified if investors would use the same forecasted rate as the best predictor of all distant rates because of the uncertainties attached to expectations of future rates in different but distant future periods the major innovative result of our paper is a formal proof that flattening of yield curves for par bonds is inevitable for long maturities the power of this proof is that no assumptions are required about forward rates zero coupon

reviews of the 2006 economic report of the president the u s tax system in international perspective a review of the 2006 economic report of the president s tax chapter 1 alan j auerbach university of california berkeley and nber april 12 2006 what can you say about a tax reform proposal that died this was the challenge facing the writers of the chapter on taxation for the 2006 economic report of the president hereafter erp one year ago the erp included a chapter entitled options for tax reform that began with the section heading why do we need tax reform and proceeded to lay out the available options that it suggested could make the u s tax system simpler more equitable and efficient in making the case for tax reform that chapter set the stage for the impending work of the president s advisory panel on tax reform while being careful to leave the president s options open until the panel reported the 2005 chapter twice included the phrase the president has not endorsed any specific proposal and this chapter does not advocate the adoption of any particular prototype for reform in case the reader didn t get the message the first two times the chapter concluded with a reminder that the president has not endorsed any specific proposal 2 that was then in november 2005 the tax reform panel issued its report so one might have anticipated a follow up chapter in this year s erp evaluating the panel s i am grateful to rosanne altshuler bill gale kevin hassett and joel slemrod for comments on an earlier draft slemrod 2005 provides a critical evaluation of the 2005 chapter

intergenerational transfers and the accumulation of wealth h t ouseholds acquire wealth from two sources they save out of income they have earned and they receive transfers from other people the first method of wealth accumulation goes under the name of life cycle saving in which people save during their working lives and dissave after retirement the second involves either an inter vivos transfer that is a transfer between living people or a bequest a transfer that occurs at the death of the donor while inter vivos transfers and bequests will arise in dynastic models where preferences include a taste for the well being of one s descendents few empirical life cycle models reflect these concerns indeed a sharp debate has arisen over the ability of the simple life cycle model to explain observed wealth accumulation understanding the relative sizes of these sources of wealth accumulation affects a variety of issues for example the effects of government debt social insurance public transfer programs estate taxes and incentives for charitable giving depend to some extent on the magnitude and nature of private saving and transfers of wealth analyses of the inequality of wealth may depend on whether most of wealth is earned or received as transfers appropriate policies for encouraging private saving may look rather different depending on whether most saving is to be consumed later in life or passed along to the next generation finally evidence on transfer patterns relates to more fundamental

growth effects of shifting from a graduated rate tax system to a flat tax i introduction recently the debate concerning fundamental u s tax reform has led to a number of proposals that involve a shift toward a consumption based system 1 one such proposal is the so called flat tax of hall and rabushka 1995 the flat tax would apply a single tax rate to all labor income above a given threshold and to all capital income after fully expensing investment expenditures hall and rabushka 1995 argue that the adoption of their proposal would provide an enormous boost to the u s economy by dramatically improving incentives to engage in productive activities and would save taxpayers hundreds of billions of dollars in compliance and administration costs 2 in this article we develop a quantitative general equilibrium model to assess the growth effects of adopting a flat tax plan similar to the one proposed by hall and rabushka 1995 the model captures many of the features of the current u s tax code such as graduated personal tax rates a standard personal deduction separate tax rates applied to personal and business income double taxation of business income and differential tax treatment of physical and human capital under appropriate parameter settings the model can exhibit either endogenous or exogenous long run growth our choice of functional forms facilitates a closed form solution to the model this allows us to characterize explicitly the economy s transition path following the reform a central issue in the debate over fundamental tax reform is the effect that such a reform would have on economic growth the present analysis builds on the work of stokey and rebelo 1995 who use an endogenous growth framework to identify the key model features and parameters that are important for determining the quantitative impacts of distortionary taxes on long run growth 3 our study differs from theirs and the bulk of the dynamic tax literature in one fundamental respect here we evaluate the growth effects of shifting from a graduatedrate tax system to a flat rate system stokey and rebelo 1995 consider only flat rate systems in which the marginal tax rate is equal to the average tax rate we approximate the graduated rate tax system in the u s economy by an empirical tax rate function that allows the personal tax rate to depend positively on household taxable income in equilibrium household decisions are influenced by both the level and slope of the tax schedule to implement the flat tax reform we shift the parameters of the tax rate function to flatten the marginal tax schedule while maintaining revenue neutrality our methodology treats the hall rabushka proposal as one that in effect moves a representative household from one tax rate schedule to another we view this setup as a reasonable approximation to gauge the growth effects of tax reform at the macro level a more elaborate setup would of course allow for household heterogeneity at a given point in time in this regard we note that caucutt et al 2003 have recently examined the growth effects of graduated rate taxes in a two period overlapping generations model that includes both skilled and unskilled agents in their model a flatter tax schedule increases the fraction of skilled agents in the economy the share of total output devoted to education rises accordingly and the economy s long run growth rate is observed to increase the quantitative implications of their model are difficult to compare to ours however because their two period framework implies a very long time horizon between household decisions about 30 years moreover their model abstracts from many of the features of the u s tax code that we include here in addition to examining the consequences of flattening the marginal tax schedule we investigate the growth effects attributable to other parts of the flat tax proposal such as allowing full investment expensing eliminating the double taxation of business income and increasing the standard personal deduction

consumption vs wage taxation and the capital levy abstract based on a representative consumer framework it has been argued that wage taxation is inferior to consumption taxation this note shows that the opposite result may emerge in a model where households are heterogeneous and where a uniform poll tax or subsidy is available

callable bonds a risk reducing signalling mechanism the theory of financial economics has failed to distinguish advantages of callable bonds from those of short term debt this paper shows that either type of borrowing can signal a firm s better prospects but that short term debt does so at the cost of weakened risk sharing with capital markets by issuing either equity or long term non callable debt a firm with poor investment opportunities will not pool its prospects with those of a better firm but equity produces superior risk sharing perhaps this explains the almr ost complete absence of long term non callable bonds from observed corporate capital structures financial theory has found only moderate success in explaining the routine inclusion of call provisions among the covenants of corporate bonds in the absence of market imperfections or incompleteness the incremental compensation promised to bondholders should exactly offset the value of the call provision retained by equityholders indifference should obtain 1 nevertheless it is hard to accept indifference as an explanation given the near universality of call provisions in corporate bond contracts in this paper we argue that in the presence of asymmetric information about investment quality corporate managers can signal their firm s better prospects by issuing bonds that include call provisions our major result shows that this signalling mechanism can be more attractive to risk averse managers than would be the choice of short term debt which could also serve to signal furthermore we demonstrate that non callable corporate debt is a dominated security that is both it and equity signal bad news but equity provides risk sharing this finding helps to explain the relative absence of long term non callable debt from corporate financial markets previous attempts to explain the prevalence of call provisions in corporate bond contracts fall into four categories two categories involve pure wealth transfers from bondholders to stockholders in these constant sum environments a gain to one group constitutes a loss to the other in the first category managers possess private information with regard to future interest rate movements issuing callable bonds will capture gains for stockholders when anticipated drops

bequest motives a comparison of sweden and the united states this paper reviews four well known theoretical models of private bequest behavior notes their differing implications for public policy and discusses a way of empirically dis criminating among them then it implements the test with micro data from sweden lls and the u s psid the so called altruistic or dynastic model which among the four models has perhaps the most wide ranging implications for policy receives some support the sign pattern is as the model predicts while the magnitude is much smaller than the altruistic theory implies there is evidence of a potential complication due to a dependence of children s education on parents financial status in the case of the u s 2001 elsevier science b v all rights reserved

nit picking the macroeconomic effects of a negative income tax i study a revenue neutral reform of the u s income tax and welfare system that involves the adoption of a negative income tax nit the reform is undertaken in a life cycle economy with individual heterogeneity and uninsurable idiosyncratic labor risk the optimal nit consists of a 22 rate and a transfer equivalent to 11 of per capita gdp the ex ante average welfare gain is a 2 1 annual increase of individual consumption i show that a nit outperforms a flat tax reform income tax plus deduction by a considerable margin the key consequence of the reform is that high productivity agents increase their relative importance in the labor supply at the expense of low productivity agents
