Bawa [3] has argued that mean-lower partial moment portfolio selection rules are more general than mean-variance rules in that they rely on fewer restrictive assumptions regarding investor utility functions and/or distributions of security returns. As with the mean-variance model, it is possible to formulate equilibrium security prices under the assumption that expected utility-maximizing investors utilize mean-lower partial moment portfolio selection rules. This paper has investigated the empirical relationship between the resultant mean-lower partial moment pricing model and the long established mean-variance pricing model.

This paper differentiates between country risk--the probability that a country will default on its obiigations--and two forms of international banking risk: (1) the extent to which a bank's foreign activities affect the cost of equity capital; and (2) the extent to which a bank's foreign activities affect the probability of bankruptcy. The paper focuses on the latter form of international banking risk.

Using Chebyshev's Inequality, it is pointed out that the risk of bankruptcy is influenced by the mean as well as the variance of the return distribution. Consequently, restrictions on the (international) composition of a bank's portfolio may increase rather than reduce the probability of bankruptcy.

This paper presents a multiperiod model of a deposit-type mutual financial institution and analyzes the manager's capital accumulation and deposit pricing decisions under uncertainty. The model is meant to describe a mutual savings and loan association (SLA) or a credit union in which there are no stockholders and nominal ownership is widely diffused (see [12] and [14]). The resulting paucity of monitoring gives rise to an agency problem (see [13]) in which the manager maximizes his multiperiod expected discounted utility with minimal intervention from nominal owners.

As an extension of previous works, we develop a theoretical framework for the relationship between monetary changes and market risk premia. The wealth effect and the return variability effect of money are shown to be the two important channels of the monetary impact on the market risk premium for three representative classes of utility functions. The theory also states that the market risk premium will be an increasing function of monetary changes given that the two component effects of money are positive.

A key assumption behind the traditional capital asset pricing model (CAPM) is the joint normality of security returns. Recently, however, this assumption has been relaxed in at least two directions. First, the emergence of continuous-time models has shifted emphasis from discrete-time random variables to continuous-time diffusion processes, with log-normality (as opposed to normality) for security prices in the stationary case. Second, the recognition that the CAPM is difficult to test empirically has led to the development of an asset pricing theory based on an arbitrage argument in large markets and free of any distributional assumption.
