A microstructure examination of trading activity following stock splits

In a study of 1,131 stock splits spanning the period 1983–1989 we observe an increase in the number of trades as well as a reduction in the mean trade size following the split. Combined with earlier reported findings of an increase in the number of shareholders postsplit, we conclude that the number of liquidity traders increases after a split. We confirm the previously observed increase in the bid-ask spread following a split, and upon decomposition of the spread find an increase in its adverse selection component in the postsplit period. This is consistent with the finding by Brennan and Hughes (1991) of an increase in the number of analysts following a stock after a split. Further, observing a decrease in market depth following a split we determine that Kyle-type models incorporating diverse private information for informed traders most correctly describe the nature of security trading. Since this decrease in postsplit market depth is not related to the trading volume or the split factor, we reject price correction explanations for stock splits.     

Agency theory and the influence of equity ownership structure on corporate diversification strategies

We articulate the agency theory view of managerial decision making and its implications for corporate diversification strategies. From agency theory, we generate testable predictions for the relation between equity ownership structure and diversification strategies and review the existing evidence on this relation. On balance, the evidence strongly supports the view that ownership structure influences corporate strategy. Copyright © 1999 John Wiley & Sons, Ltd.     

Review of: “ EXPERIMENTS ON DECISIONS WIDER RISK: THE EXPECTED UTILITY HYPOTHESIS ” by Paul J. H. Schoemaker,Martinos Nijhoff Publishing,Boston, 1980, xxii + 211 pages,list $18.95.

Almost every capital budgeting textbook has a chapter on the weighted average cost of capital (WACC). Though this is theoretically satisfying, it does not describe how companies actually operate. The WACC calls for a balanced capital structure in which debt and equity are utilized at some predetermined percentage. The problem is that researchers have shown that firms try to avoid selling new shares whenever possible. This leads to the pecking order theory in which firms first use internal funds, then low-risk debt, then high-risk debt, and finally, as a last resort, new common stock. There is no attempt to balance the capital structure. This survey study basically confirms that approach.     

The Costs of Issuing Preferred Stock

U.S. firms commonly use preferred stocks to raise external capital. Yet this hybrid security's issuance costs and offer yields have not been previously examined in a systematic manner. We analyze a sample of 3,042 U.S. preferred stocks issued between 1980 and 1999. We find that convertible issues, which are riskier than straight issues, entail higher gross spreads and other direct expenses. Scale, credit rating, and industry effects influence gross spreads and issuance costs. We also compare preferred stocks yields with various bellwether bond yields. Our results support the tax‐based argument that suggests that yields on preferred stocks should be lower than comparable risky bonds.     

First among Equals: The Effect of Team Leader Characteristics on the Internal Dynamics of Cross‐Functional Product Development Teams*

Drawing on the path‐goal theory of leadership, the present study examines the effect of team leader characteristics on an array of conflict resolution behavior, collaboration, and communication patterns of cross‐functional new product development (NPD) teams. A hierarchical linear model analysis based on a survey of 246 members from 64 NPD teams suggests that participative management style and initiation of goal structure by the team leader exert the strongest influence on internal team dynamics. Both these leadership characteristics had a positive effect on functional conflict resolution, collaboration, and communication quality within the NPD team while discouraging dysfunctional conflict resolution and formal communications. Comparatively, team leader's consideration, initiation of process structure, and position had a surprisingly weak effect on internal team dynamics. Further, the findings underscore the differential effects on various dimensions of team dynamics, the importance of controlling for project and team characteristics, and the use of multilevel modeling for studying nested phenomena related to NPD teams. Implications of these findings are discussed.     

Generalized contest success functions

The key element of models of contest is the contest success function (CSF) which specifies the winning probabilities of agents. The existing axiomatizations of CSFs assume that contestants can make only one type of investment. This paper generalizes these axiomatizations to the case where each agent can have multiple types of investments. This allows us to provide a unified framework to extend and interpret the results of Skaperdas (Econ Theory 7:283–290, 1996) and Clark and Riis (Econ Theory 11:201–204, 1998), and rationalize some seemingly ad hoc CSFs used by applied researchers. This paper has benefitted from the comments of Aicke Hinrichs, Rene Levinsky, and two anonymous referees. We are especially thankful to one of the referees for detailed comments which have helped improve every aspect of this paper.     

Naive Reinforcement Learning With Endogenous Aspirations

This article considers a simple model of reinforcement learning. All behavior change derives from the reinforcing or deterring effect of instantaneous payoff experiences. Payoff experiences are reinforcing or deterring depending on whether the payoff exceeds an aspiration level or falls short of it. Over time, the aspiration level is adjusted toward the actually experienced payoffs. This article shows that aspiration level adjustments may improve the decision maker's long-run performance by preventing him or her from feeling dissatisfied with even the best available strategies. However, such movements also lead to persistent deviations from expected payoff maximization by creating 'probability matching' effects.     

The Impact of Options Trading on the Market Quality of the Underlying Security: An Empirical Analysis

We find that option listings are associated with a decrease in the variance of the pricing error, a decrease in the adverse selection component of the spread, and an increase in the relative weight placed by the specialist on public information in revising prices for the underlying stocks. We also find that there is a decrease in the spread and increases in quoted depth, trading volume, trading frequency, and transaction size after option listings. Overall, our results suggest that option listings improve the market quality of the underlying stocks.
