Among the numerous familiar sets of specific assumptions sufficient to derive mean-variance portfolio behavior from more general expected utility maximization in continuous time, the assumptions of constant relative risk aversion and joint normally distributed asset return assessments are also...

This paper re-examines the effects of nominal contracts on the relationship between unanticipated inflation and individual stock's rate of return. This study differs in three main ways from previous research. First, announced inflation data are used to examine the effects of unanticipated...

The three sections of this paper support three related conclusions. First, asset demands with the familiar properties of wealth homogeneity and linearity in expected returns follow as close approximations from expected utility maximizing behavior under the assumptions of constant relative risk...

When all financial assets have risky returns, the mean-variance portfolio model is potentially subject to two types of bliss points. One bliss point arises when a von Neumann-Morgenstern utility function displays negative marginal utility for sufficiently large end-of-period wealth, such as in...

Previous research finds that fundamental macroeconomic news has little effect on stock prices. This study shows that after allowing for different stages of the business cycle, a stronger relationship between stock prices and news is evident. In particular, the empirical results suggest that the...

The symmetry restriction in a system of financial asset demands has frequently been employed to reduce the number of independent parameters to be estimated. The theoretical implications of the symmetry restriction are examined in this paper, and it is found that symmetry implies a particular...
