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...

The ratio of outstanding debt to gross national product in the United States has shown essentially no time trend over a period measured not in years but in decades. The research reported in this paper indicates that lenders' portfolio behavior exhibits characteristics that could provide...

Among the different kinds of economic behavior which may account for the familiar Fisherian relationship between nominal interest rates and expected price inflation, portfolio behavior is the most plausibly flexible in the short run. Since substitution into real assets is not a practical...

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...

This paper summarizes some recent work in which we have modeled long-term interest rate determination in an explicit demand-supply context, using multi-equation structural models and directly contrasts such models with unrestricted reduced-form models. Wholly apart from questions of...
