Underpricing,Share Overhang,and Insider Selling in Follow‐on Offerings

Prospect and information‐momentum theories predict that insiders can offer fewer shares in an initial public offering (IPO) to create informational momentum and obtain higher prices in follow‐on offerings. I find that dilution and insider participation in the IPO are negatively related to the number and size of follow‐on offerings, consistent with the prediction. However, insider selling in follow‐on offerings is positively related to IPO selling, contrary to the theories. Returns around follow‐on offering announcements are more negative for newly public firms than older firms, but for newly public firms do not differ by whether the announcement comes before or after the lockup expiration date.

Cumulative prospect theory and the St. Petersburg paradox

Summary. We find that in cumulative prospect theory (CPT) with a concave value function in gains, a lottery with finite expected value may have infinite subjective value. This problem does not occur in expected utility theory. The paradox occurs in particular in the setting and the parameter regime studied by Tversky and Kahneman [15] and in subsequent works. We characterize situations in CPT where the problem can be resolved. In particular, we define a class of admissible probability distributions and admissible parameter regimes for the weighting- and value functions for which finiteness of the subjective value can be proved. Alternatively, we suggest a new weighting function for CPT which guarantees finite subjective value for all lotteries with finite expected value, independent of the choice of the value function. Some of these results have already been found independently by Blavatskyy [4] in the context of discrete lotteries.Received: 14 October 2004, Revised: 6 May 2005, JEL Classification Numbers: C91, D81.We thank Pavlo Blavatskyy and Thorsten Hens for their helpful remarks regarding our paper. Moreover, we thank the referee for his constructive suggestions.

Overestimating Oneself and Overlooking the Law: Psychological Supports for Employment at Will

This article studies the hypotheses that people tend to underrate other people's work motivation and skills relative to their own, and further tend to be unaware of the legal status of employment at will in contemporary U.S. law. The theoretical part of the article describes psychological bases for the hypothesized tendencies and explains how they can be expected to foster acquiescence to employment at will and high employment insecurity. The empirical portion of the article describes and discusses a survey of M.B.A. students that probed their knowledge of and attitudes toward U.S. employment law, along with their attitudes toward employment insecurity and work motivation. Consistent with the hypotheses, the study found widespread lack of knowledge about the legal status of employment at will, as well as a tendency toward overrating one's own work motivation relative to others and a tendency toward taking higher risks of termination when they were presented as controllable on an individual, though not a group, basis.
