This paper presents and implements a procedure which examines for empirical support for the location and scale condition. The Kolmogorov-Smirnov multisample test is used to determine if the distribution functions describing the nonsystematic risk component of rate of return for portfolios of...

If the elements of the choice set in a decision model involving randomness are not arbitrary, but restricted appropriately, an expected utility ordering of them can be represented by a mean standard deviation ranking function. These restrictions can apply to the form of, or can specify...

This paper takes an additional step toward analyzing the demand for insurance in the context of a portfolio model. An investor is endowed with a portfolio containing a risky and riskless asset that can be augmented by purchasing insurance. Here, insurance is paid for by reducing the quantity of...

Two-moment decision models are consistent with expected utility maximization only if the choice set or the agent's preferences are restricted. All currently available restrictions, such as quadratic utility or normality, are either theoretically deficient and/or empirically rejected. This paper...

This paper investigates aspects of insurance demand related to deductible insurance. In particular, an important issue concerning analysis of the optimal deductible level is resolved. A simple sufficient restriction on the pricing of insurance is given which ensures that the second order...

In this article, a general class of deterministic transformations that can be interpreted as changes in risk are identified. This provides a fourth characterization of a Rothschild-Stiglitz increase in risk. In addition, a particular subclass of these transformations, termed simple...
