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. [ABSTRACT FROM AUTHOR]

In the spirit of Harberger, we apply a dynamic computable general equilibrium (CGE) model and estimate the excess burden stemming from the tax-induced distortion in the allocation of capital across the corporate and the non-corporate sectors in Germany. In doing so, we perform a counterfactual analysis and ask how the allocation of capital across sectors would change compared with a sector-neutral tax system which assures an identical effective tax burden on both sectors. Our estimates suggest that the excess burden per-period amounts to approximately 2.2 billion Euros or to about 0.1 per cent of GDP. In present value terms, the excess burden translates to about 89 billion Euros or 4.0 per cent of GDP. In order to identify the impact of the firm’s financial behaviour on the size of the emerging excess burden, we perform several sensitivity analyses with regard to debt financing, external equity financing and debt constraints via agency cost.

Can reductions in domestic capital income taxes attract foreign capital and, at the same time, foster economic growth? Using a two-country overlapping generations model with endogenous growth and internationally mobile capital, this paper shows that the effect of domestic capital taxes on the international allocation of capital and on the rate of economic growth do not necessarily go in the same direction. A country can attract capital by reducing its taxes, but this may lower the rate of economic growth depending on the elasticity of saving to the net-of-tax interest rate and on the effect of taxes on domestic factor productivity.

This paper examines the taxation of capital income in a small open economy that faces a highly elastic supply of internationally mobile capital and increasing tax competition. The analysis considers a wide variety of additional factors that affect the determination of capital income taxation policy, including the desire to tax economic rents earned by foreign and domestic firms, the desire to take advantage of any treasury transfer effects, the role played by transfer pricing and other financial accounting manipulations by foreign multinationals, the need for a backstop to the personal income tax and various political concerns. The paper evaluates several potential income and consumption-based tax reforms in this context. [ABSTRACT FROM AUTHOR]

We examine the impact of flat-rate taxes on intergenerational equity in an overlapping generations model of a small open economy, assuming the intergenerational externality of human capital accumulation. The externality may cause the difference between the growth rates in private human capital and in average human capital of the economy. If the externality is sufficiently small, the introduction of an interest income tax will benefit all future generations. In contrast, if it is sufficiently great, the introduction of a wage tax could harm all generations by raising financial asset holdings and thereby reducing consumption. [ABSTRACT FROM AUTHOR]

The Netherlands has abolished the tax on actual personal capital income and has replaced it by a presumptive capital income tax, which is in fact a net wealth tax. This paper contrasts this wealth tax with a conventional realization-based capital gains tax, a retrospective capital gains tax with interest on the deferred tax, and a mark-to-market tax which taxes capital gains as they accrue. We conclude that the effective and neutral taxation of capital income can best be ensured through a combination of (a) a mark-to-market tax to capture the returns on easy-to-value financial products, and (b) a capital gains tax with interest to tax the returns on hard-to-value real estate and small businesses.

This paper provides a general equilibrium analysis of the effects of a foreign tax credit (FTC) provision on current account dynamics of a small, open economy. Because of the asymmetric functioning of FTC, the rate of return on domestic capital is determined by the arbitrage of the marginal investor, the investor in the creditor country. Thus a change in the home country capital income tax rate causes different responses in long-run foreign asset holdings and the current account dynamics depending upon whether the country is a net creditor or debtor and upon whether the country has a higher tax rate than the foreign country or not.

The welfare cost of capital income taxation is analyzed utilizing intertemporally dependent preference operationalized using a variable rate of time preference. It is shown that if households exhibit increasing marginal impatience, then the welfare cost of capital income taxation is inversely related to the elasticity of the rate of time preference with respect to consumption. Therefore, the welfare cost of capital income taxation reported using time additive preferences may not be robust. Numerical examples show that the use of time additive preferences could result in the welfare cost of capital income taxation to be overestimated by as much as 25%. [ABSTRACT FROM AUTHOR]
