A negative report on the ‘near optimality’ of the max-expected-log policy as applied to bounded utilities for long lived programs

Much controversy surrounds the use of the portfolio investment rules induced by maximizing the expected logarithm of terminal wealth (henceforth referred to as the MEL policy). It has been thought that the MEL policy is a good approximation to the optimal investment program when the utility of terminal wealth function is bounded and when the time horizon is long. However, I exhibit a class of bounded utility of terminal wealth functions for which the MEL policy is a very poor approximation to the optimal program. Hence, the wholesale use of the MEL policy as an approximation to the optimal program is unwarranted.     

Salesperson stereotypes,consumer emotions,and their impact on information processing

This study examines salesperson stereotypes and their effect on the selling environment. After reviewing relevant literature, the authors advance a hierarchical structure of salesperson stereotype categories. Experimental results suggest that stereotypes influence consumer emotions, and these emotions then mediate the relationship between stereotype activation and subsequent consumer cognitions.

The characteristics and survival of public interest groups

Conclusion There is no reason to assume that pressure groups will further the public interest, however defined. Generally, pressure groups are formed to benefit the members of the group. Those interest groups that form to exert political pressure will be characterized by the distribution of benefits within the group as well as by the net benefits of organizing. These same factors will discourage other groups from organizing. Because of the public good characteristic, pressure groups must avoid the free rider problem. Thus, interest groups tend to be short lived. In the short run, they can solve this problem by providing some divisible benefits, and small groups can use social pressure. In the long run, membership must depend on coercion or institutionalized advantage.
