International asset demands are functions of expected returns.Optimal portfolio theory tells us that the coefficients in this relationship depend on the variance-covariance matrix of real returns.But previous estimates of the optimal portfolio (1) assume expected returns constant and (2) are not...

The theoretical and empirical results in this paper make a strong prima facie case for the proposition that increases in the after tax rate of return caused by tax policy are likely to bring forth significant increases in saving. Theoretical analysis using a variety of standard models tends to...

Using a continuous-time finance-theoretic framework, this paper presents the optimal portfolio rule of an international investor who consumes N national composite goods and who holds N domestic-currency-denominated assets with known nominal interest rates in an environment where prices of goods,...

This paper presents evidence that the corporate stock owned by high income investors appreciates substantially faster than the stock owned by investors with lower incomes. Those with very high incomes enjoy the greatest success on their investments while those with incomes under $20,000 have the...

The purpose of this paper is to present and estimate a model which allows one to use the recently computerized U.S. Patent Office's data base to identify when and where changes in inventive output have occurred. The model assumes a firm which chooses a research strategy to maximize the expected...

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...

One of the best documented propositions in the field of finance is that, on average, investors have received higher rates of return on in- vestment securities for bearing greater risk. This paper looks at the historical evidence regarding risk and return, explains the fundamentals of portfolio...

Enormously diverse real and nominal ex post returns on equity and short and long term debt securities have accompanied substantial variations in inflation and resource utilization during the past half century. This paper contains an examination of the relationships among these security returns...

This paper examines the empirical relation between stock returns and dividend yields. Several equilibrium pricing models incorporating differential taxation of dividends and capital gains are nested as systems of time series regressions. Estimates of these models and tests of parameter...

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...
