This paper analyzes optimal linear and non-linear taxes on capital and labor incomes in a life-cycle model of human capital
investment, financial savings, and labor supply with heterogenous individuals. A dual income tax with a positive marginal
tax rate on not only labor income but also capital income is optimal. The positive tax on capital income serves to alleviate
the distortions of the labor tax on human capital accumulation. The optimal marginal tax rate on capital income is lower than
that on labor income if savings are elastic compared to investment in human capital, substitution between verifiable and non-verifiable
inputs in human capital formation is difficult, and most investments in human capital are verifiable so that education subsidies
can directly reduce the tax wedge on learning. Numerical calculations suggest that the optimal marginal tax rate on capital
income is substantial. 相似文献

Pawns and queens revisited: public provision of private goods when individuals make mistakes 总被引:1,自引:0,他引:1
This paper analyses the optimal tax policy and public provision of private goods when the government is paternalistic and
has a redistributive objective. When individuals only differ with respect to their income-earning abilities, the publicly-provided
goods should be overprovided, relative to the decentralised optimum, if society’s marginal valuation of them exceeds the individual
valuation and if these goods are complements to labour supply. However, when the individuals also differ in terms of their
valuation of the publicly-provided good, this simple conclusion does not hold. Optimal marginal income tax rates are shown
to differ from the standard rules if publicly-provided goods and labour supply are related.

A worker can reduce tax liability by contributing to a private pension plan when marginal tax rates are high and withdraw pension benefits when marginal tax rates are low. We quantify the tax benefit of income smoothing through the private retirement system and find that it is negligible. This conclusion is important to households, investment advisers, tax policymakers, and scholars engaged in financial retirement planning. 相似文献

This paper shows that the divine‐coincidence does not hold in a sticky price model with external habit if a time‐varying tax rate on labor income is not implemented to fully eliminate the time‐varying distortions associated with external habit and monopoly power in goods market. The required labor income tax rate is inversely related to the risk‐free real interest rate and the markup in the goods market, but it is proportional to the degree of external habit. Under this circumstance, the optimal monetary policy commands a countercyclical interest rate, having a perfect negative correlation with tax rate in the sticky price model with external habit. If a time‐invariant tax is the only fiscal instrument, then the degree of external habit entails a gap between the private marginal rate of substitution between consumption and labor and the social marginal rate of substitution, generating an endogenous trade‐off between the stabilization of welfare‐relevant output gap and inflation. Under this circumstance, price stability is not the optimal policy. The monetary policy authority should optimally try to undo the time‐varying distortions associated with external habit and monopoly power in goods market by deviating from price stability. 相似文献

This paper studies optimal linear and non-linear income taxes and education subsidies in two-type models with endogenous human capital formation, endogenous labor supply, and endogenous wage rates. Assuming constant human capital elasticities, human capital investment should be efficient under optimal linear policies, whether general equilibrium effects are present or not. Hence, education subsidies should not be used for distributional reasons. Due to general equilibrium effects, optimal linear income taxes may even become negative. Optimal non-linear policies exploit general equilibrium effects for redistribution. The high-skilled type optimally has a negative marginal income tax rate and a positive marginal education subsidy. The low-skilled type optimally faces a positive marginal income tax rate and a marginal tax on education. Simulations demonstrate that general equilibrium effects have only a modest effect on optimal non-linear policies. 相似文献

This study provides evidence that, when “hard” freezing their defined benefit pension plans, employers select downward biased accounting assumptions to exaggerate the economic burden of their benefit plans. Downward biased expected rates of return and discount rates allow managers to increase reported pension expenses and, for discount rates, allow managers to increase reported pension liabilities. We find that prior to the Sarbanes-Oxley Act, both rates are downward biased when firms freeze their plans, whereas after SOX the bias is lower. This finding is consistent with managers opportunistically biasing pension estimates to obtain labor concessions during periods of reduced regulatory scrutiny. 相似文献

This article provides an integrated analysis of pension funding and corporate financing strategies in the presence of default risk. The article shows that when the marginal personal income tax rate is constant, the financing decision with respect to pension funding is influenced entirely by tax considerations. When the marginal personal income tax is progressive, the optimal financing of pension funding depends on the cyclical nature of the firm (as characterized by the sign of beta), the riskiness of pension assets, and ERISA regulations concerning the pension-benefit guaranty rate, the marginal pension insurance premium and the firm's legal responsibility for its unfunded pension obligations. It is shown that a necessary condition for partial pension funding is that the marginal insurance premium imposed by PBGC must be less than actuarially fair, and a necessary condition for pension funding to be financed by both debt and equity is that beta must be positive. 相似文献

We examine a linear capital income tax and a nonlinear labor income tax in a two-type model where individuals live for two
periods. We assume that taxes are paid only in the second period in which the agents receive both labor and capital income
and may shift income from labor to capital. The two types of individuals may differ with respect to wage rate and initial
resource endowments. In the absence of income shifting, endowment variation motivates a capital income tax which would not
exist where there is pure wage rate variation. In the latter circumstance, income shifting would indeed establish a case for
a capital income tax while adding variation in resource endowments would ambiguously affect the case. The asymmetric information
case for a capital income tax must be traded off against distortionary effects not only on savings, but also on labor as an
agent may earn labor income which is reported and taxed as capital income.

We formulate a two-period life cycle model of saving, labor supply, and human capital investment when individuals differ in their ability and initial wealth. Borrowing constraints result in sub-optimal choices for consumption and investments in human capital. We analyze optimal linear income taxes and education subsidies. The optimal income tax is shown to be positive—even in the absence of any redistributional concerns. A redistributive income tax relaxes borrowing constraints by redistributing resources from the unconstrained to the borrowing constrained stages of the life cycle. The income tax thus alleviates preexisting non-tax distortions in the capital market. Human capital is subsidized on a net basis in the absence of redistributional concerns. Education subsidies help to relax credit constraints and to reduce distortions from explicit and implicit taxes on human capital formation. When redistributional concerns are present, education is subsidized more if this helps to alleviate distortions on labor supply, but is subsidized less if education subsidies have a very regressive incidence. Simulations demonstrate that optimal income taxes are substantially higher when credit constraints are present. Education is generally subsidized on a net basis, and the more so if credit constraints are more severe. 相似文献

We characterize optimal redistribution policy when there are differences not only in individuals’ productivities but also in their tastes towards the timing of consumption, i.e. some are patient and others impatient in consumption over the life cycle and this preference together with productivity is non-observable to government. We consider different social objectives and incorporate a novel approach taken in the spirit of Roemer (Equality of opportunity, Harvard University Press, Harvard, 1998) and Van de Gaer (Equality of opportunity and investments in human capital, Katholieke Universiteit Leuven, 1993). This approach applies a compromise between the principle of compensation and the principle of responsibility. We derive analytical expressions which describe the optimal distortion (upward or downward) in saving. As the multidimensional problems become very complicated, to gain a better understanding, we also numerically examine the properties of an optimal lifetime redistribution policy. We find support for a nonlinear tax/pension program in which impatient types are taxed at the margin, and patient low ability types are subsidized in their retirement consumption. Numerical simulations show quite big differences in terms of the levels of marginal tax rates between different social objectives, indicating that the optimal income taxation results are sensitive to the choice of the social planner’s goals. 相似文献

The Tepper–Black arguments for tax-arbitrage opportunities from overfunding pension plans are critically examined and modifications proposed. Tax status, a function of current marginal tax rates and expected future taxable income, is predicted to determine funding policy. Tests of this modified tax benefits view suggest that 1) tax status declines are associated with pension contribution reductions, 2) reductions in contributions are related to previous excess contributions as well as non-pension tax shield increases causing the decline in tax status, and 3) cross-sectionally, tax status is related to fund levels, choice of actuarial variables, and the use of defined benefit plans. 相似文献

This paper concerns redistribution via nonlinear income taxation in an overlapping generations model with two ability-types.
We assume that the wage rates are determined by bargaining between unions and firms, meaning that the equilibrium is characterized
by involuntary unemployment. We show that the policy instruments that are used to calculate the marginal labor income tax
rate for each ability-type give rise to intertemporal tax base effects. In addition, since the relationship between the employment
and the capital stock implies intertemporal production inefficiency at the second best optimum, imperfect competition in the
labor market may itself justify capital income taxation.

A substantial literature addresses the design of transfer programs and policies, including the negative income tax, other
means-tested transfers, the earned income tax credit, categorical assistance, and work inducements. This work is largely independent
of that on the optimal nonlinear income tax, yet formulations of such a tax necessarily address how low-income individuals
should be treated. This paper draws on the optimal income taxation literature to illuminate the analysis of transfer programs,
including the level and shape of marginal tax rates (including phase-outs), the structure of categorical assistance, and the
role of work inducements in an optimal income transfer scheme.

It is often argued that the observed trend towards early retirement is due mainly to the implicit tax imposed on continued activity of elderly workers. We study the relevance of such a distortion in a political economy model with endogenous age of retirement. The setting is a two-period overlapping generations model. Individuals differ in their productivity. In the first period they work a fixed amount of time; in the second, they choose when to retire and then receive a flat rate pension benefit. Pensions are financed by a payroll tax on earnings in the first and in the second period of life. Such a tax is non distortionary in the first period; it is distortionary in the second period. We allow for some rebating of the second period tax. Individuals vote on the level of the payroll tax given the rebate which can range from 0 (biased system) to 100% (neutral system). We provide sufficient conditions for the existence of a voting equilibrium and study its properties. Under these conditions, high tax rates are supported by all the old and by low productivity young individuals. We show that the pivotal voter is a young individual. The number of young individuals who have higher wage than the pivotal voter equals half the total population. We also show that the introduction of a bias increases the political support for the pension system. Finally, we study the simultaneous determination of the bias and the tax rate through a voting procedure and show that the equilibrium (if any) implies a bias which is always positive and may or not be larger than one. 相似文献

If the effective tax rates on ordinary income and capital gains are identical, the assumption of independence or dependence between ordinary income and capital gains tax rates is shown to have no impact on discount bond valuation or risk. However, even if the effective tax rates are identical, the shape and the sensitivity of the bond valuation and risk functions with respect to taxes are not identical under the alternative assumptions. A mathematical and numerical analysis of the sensitivity of changes in the discount bond valuation and risk functions with respect to income tax rates is provided. Comparisons between the sensitivities of changes in the discount bond valuation and risk functions and taxes under conditions of dependence or independence between ordinary income and capital gains tax rates are made. 相似文献

Miller and Scholes (1978) hypothesize that the marginal tax rate on dividend income may be less than the marginal rate of tax on capital gains. Their hypothesis is dependent upon individuals utilizing existing provisions of the Code which serve to reduce the taxation of dividends. In this study, estimates of the marginal and effective rates of tax on dividend income for the year 1979 are presented using the Statistics of Income sample of returns. The average marginal rate of tax on dividend income is estimated to be 40%, while the average effective rate of tax is estimated to be 30%. 相似文献

Existing term structure models of defaultable bonds have often underestimated corporate bond spreads. A potential problem is that investors’ taxes are ignored in these models. We propose a pricing model that accounts for stochastic default probability and differential tax treatments for discount and premium bonds. By estimating parameters directly from bond data, we obtain significantly positive estimates for the income tax rate of a marginal corporate bond investor after 1986. This contrasts sharply with the previous finding that the implied tax rates for Treasury bonds are close to zero. Results show that taxes explain a substantial portion of corporate bond spreads. 相似文献

Do Managers of U.S. Defined Benefit Pension Plan Sponsors Use Regulatory Freedom Strategically?

We use historical particularities of pension funding law to investigate whether managers of U.S. corporate defined benefit pension plan sponsors strategically use regulatory freedom to lower the reported value of pension liabilities, and hence required cash contributions. For some years, pension plans were required to estimate two liabilities—one with mandated discount rates and mortality assumptions, and another where these could be chosen freely. Using a sample of 11,963 plans, we find that the regulated liability exceeds the unregulated measure by 10% and the difference further increases for underfunded pension plans. Underfunded plans tend to assume substantially higher discount rates and lower life expectancy. The effect persists both in the cross‐section of plans and over time and it serves to reduce cash contributions. We further show that plan sponsor managers use the freed‐up cash for corporate investment and that credit risk is unlikely to explain the finding. 相似文献

We develop and test a new approach to assess defined benefit (DB) pension plan solvency risk in the presence of extreme market movements. Our method captures both the ‘fat-tailed’ nature of asset returns and their correlation with discount rate changes. We show that the standard assumption of constant discount rates leads to dramatic underestimation of future projections of pension plan solvency risk. Failing to incorporate leptokurtosis into asset returns also leads to downward biased estimates of risk, but this is less pronounced than the time-varying discount rate effect. Further modifying the model to capture the correlation between asset returns and the discount rate provides additional improvements in the projection of future pension plan solvency. This reduces the perceived future risk of underfunding because of the negative correlation between interest rate changes and asset returns. These results have important implications for those with responsibility for balancing risk against expected return when seeking to improve the current poor funding positions of DB pension schemes. 相似文献
