In this paper we study the transition from a pay-as-you-go system of Social Security pensions to an investment-based system in an economy in which portfolio returns and capital profitability are both uncertain. The paper extends earlier studies by Feldstein and Samwick that modeled the...

This paper presents new estimates of the taxes paid on nonfinancial corporate capital, on the pretax rate of return to capital, and on the effective tax rate. The basic time series show that both the pretax rate of return and the effective tax rate have varied substantially in the past quarter...

We provide new measures of ethnic, linguistic and religious fractionalization for about 190 countries. These measures are more comprehensive than those previously used in the economics literature and we compare our new variables with those previously used. We also revisit the question of the...

This study provides the first econometric analysis of the effect of taxation on the realization of capital gains. The analysis thus extends and complements the earlier study by Feldstein and Yitzhaki [1978] of the effect of taxation on the selling of corporate stock. The present analysis, using...

In this paper we study the distributional impact of a change from the existing pay-as-you-go Social Security system to one that combines both pay-as-you-go and investment-based elements. Critics of investment-based plans have been concerned that such plans might reduce the retirement income of...

This paper evaluates the effects of fiscal policy on investment using a panel of OECD countries. In particular, we investigate how different types of fiscal policy affect profits and , as a result, investment. We find a sizable negative effect of public spending -- and in particular of its...

This paper studies both theoretically and empirically the determinants of group formation and of the degree of participation when the population is heterogeneous, both in terms of income and race or ethnicity. We are especially interested in whether and how much the degree of heterogeneity in...

Any arrangement that is to serve as a long-term framework for international debt management must permit a politically acceptable rate of economic growth in the debtor countries while gradually improving the financial positions of the creditor banks. In addition, a realistic debt management...

The present paper shows how a negative fiscal multiplier is possible in a two-sector economy that is otherwise similar to the traditional one-sector Keynesian analysis. The key to this surprising possibility is that an increased budget deficit changes the sectoral balance of demand. A reduction...
