The Emergence of Corporate Governance from Wall St. to Main St.: Outside Directors, Board Diversity, Earnings Management, and Managerial Incentives to Bear Risk

Recent corporate events have brought a heightened public awareness to corporate governance issues. Much work has been accomplished to date, but it is clear that much more remains to be done. This paper provides a review of empirical research in four relevant areas of corporate governance. Specifically, the paper provides an overview of (a) the role that outside directors play in monitoring managers, (b) the emerging literature on the impact of board diversity, (c) the existence of and incentives for corporate executives to manage firm earnings, and (d) managerial incentives to bear risk.     

Equity Ownership and Firm Value: Evidence from Targeted Stock Repurchases

In contrast to the negative average abnormal return associated with the announcement of a control‐related targeted repurchase (greenmail transaction), we find that the announcement of a noncontrol‐related targeted repurchase is associated with a positive and significant average abnormal return. Cross‐sectional analysis indicates that the change in firm value at the announcement of a noncontrol‐related targeted repurchase is negatively related to the resulting changes in both insider ownership and outside blockholdings. We also find significant differences in announcement‐period stock price effects depending on the identity of the selling shareholder.     

Acquisitions: Private versus Public

Takeovers of privately held companies represent more than 80% of all takeovers. Despite their significance, studies of such takeovers and their impact on the wealth of shareholders are rare. Using a very large, near exhaustive, sample of listed and privately held UK targets we examine the impact of such takeovers on the risk adjusted return of listed UK acquirers over the period 1981 to 2001. Acquirers earn significant positive returns during the period surrounding the bid announcement although the gains are dependent on target status, mode of payment, and the relative size of those involved. The much quoted conclusion, derived from the experiences of listed firm bidders that the shareholders of acquiring firms fail to gain from takeovers, cannot be generalised. Acquiring a privately held company is an attractive option for maximising shareholder wealth.     

Three approaches to teaching business ethics

The question on what the purpose of teachingbusiness ethics should be, never fails todivide opinion. In this article three basicpositions taken with regard to this questionare distinguished. They are the cognitivecompetence, the behavioural competence and themanagerial competence positions. Once the coreof each these positions has been identified,the ontological presuppositions underlying eachof them is retrieved. It is then argued thatthese three positions and their accompanyingpresuppositions should not be regarded as rivalpositions, but as complementary approaches inteaching business ethics. Finally the teachingstrategies required by each of these threepositions are discussed.     

Managerial ownership and corporate diversification: a longitudinal view

Strategy and finance research suggests that managerial ownership results in increased incentive alignment and therefore is negatively related to corporate diversification. Using a longitudinal approach, we develop arguments to examine whether managerial ownership is associated with subsequent changes in diversification and/or if diversification is associated with subsequent changes in ownership. The results indicate that levels of managerial ownership in one time period are not associated with subsequent changes in corporate diversification, which raises incentive alignment questions. We also find that higher levels of corporate diversification are associated with changes in managerial ownership, which suggests support for the employment risk‐reduction perspective. This study provides important reasons to reassess the longitudinal implications of the managerial ownership‐corporate diversification link from both theoretical and managerial perspectives.

Social influence effects and managerial compensation evidence from Germany

I extend existing theories of social influence effects on executive compensation while at the same time showing the context dependence of these effects. Using original data on German firms and a longitudinal design, results of this study suggest that the operating of social influence mechanisms depends on demographic and social similarity between CEOs and board chairs. The findings reconcile previous mixed findings on the role of CEO human capital factors such as education and tenure and furthermore show that board vigilance is conditional on board compensation and the presence of major shareholders with an incentive to monitor board behavior. Finally, the study contributes to compensation and corporate governance research by providing evidence on how social influence effects operate outside the United States.

Strategic reward systems: a contingency model of pay system design

A limited number of studies have addressed the idea of ‘strategic’ reward systems—the matching of compensation systems to a firm's strategy. Prior research on this topic has been confined to U.S. firms, however, and a number of key questions remain unanswered. Using a sample of 917 employees from two large Swiss financial institutions, we found that pay systems are linked with divisional strategic orientation, but in a different form than prior studies. Additionally, we identify hierarchical position as an important variable in the tailoring of reward systems. Hierarchy has a significant main effect on pay plan design, and an interactive effect with strategic orientation. Copyright © 2001 John Wiley & Sons, Ltd.     

Product Market Competition,Managerial Incentives and Firm Valuation

This paper contributes to the very small empirical literature on the effects of competition on managerial incentive schemes. Based on a theoretical model that incorporates both strategic interaction between firms and a principal agent relationship, we analyse the relationship between product market competition, incentive schemes and firm valuation. The model predicts a nonlinear relationship between the intensity of product market competition and the strength of managerial incentives. We test the implications of our model empirically based on a unique and hand‐collected dataset comprising over 600 observations on 200 Swiss firms over the 2002–2005 period. Our results suggest that, consistent with the implications of our model, the relation between product market competition and managerial intensive schemes is convex indicating that above a certain level of intensity in product market competition, the marginal effect of competition on the strength of the incentive schemes increases in the level of competition. Moreover, competition is associated with lower firm values. These results are robust to accounting for a potential endogeneity of managerial incentives and firm value in a simultaneous equations framework.
