How Much Investment Choice is Enough for Members?

In recent years Australians have been given increased responsibility in making investment strategy decisions for their superannuation contributions. The investment choices superannuation funds typically offer include ready-made options with a strategic asset allocation or a "do-it-yourself option where the members choose their own asset allocation. This paper examines a sample of choices by members of a large industry fund which allows members any combination of six ready-made pools and eight asset classes. About one-quarter of these decisions involve choices which suggest a possibly naïve view of diversification unless members are conscious of resulting asset allocations.     

Jury Decisions and Awards in Personal Injury Lawsuits Involving Foodborne Pathogens

A study of food poisoning jury verdicts in 32 states (1988–1997) revealed that plaintiffs won awards in food poisoning jury trials 31% of the time, and received a median award of $25,560. Multivariate analyses were performed to examine the effects of various factors on food poisoning jury verdicts and on the size of the award. The odds of a plaintiff victory increased if a foodborne pathogen or illness was specified, and decreased if defendants had “deep pockets”or used medical expert testimony. Illnesses involving hospitalization, death, or chronic complications received higher awards than other illnesses.     

The Effect of Limited Liability on the Market Response to Disclosure*

Abstract. We formalize the effects of an earnings disclosure on security prices under an assumption of limited liability. We derive various nonlinear relations between equity prices and earnings under a variety of capital structure assumptions and. if possible, we tie the relations attained to results from the existing empirical literature. We also characterize how debt prices respond to earnings when holders of debt have limited liability. Finally, we analyze how changes in the degree of leverage and conversion features of debt affect the relation between price and earnings.     

Common Stock Returns and Rating Changes: A Methodological Comparison

This paper examines the adjustments in a firm's common stock price during the eleven months before and during the month of announcement of a bond rating change. Based on several different measures of abnormal security return, the findings are consistent with the proposition that bond downgradings convey information to common stockholders. For bond upgradings, the price adjustments were statistically insignificant in the month of announcement, although in the eleven preceding months, upgraded firms exhibited positive abnormal returns. While the results do not fully support earlier research, we stress that the main contribution of this article lies in the scrutiny it gives to issues of methodology in assessing the possible price effects of bond reclassifications.
