STOCKHOLDER RETURNS AMONG HOMOGENEOUS GROUPS OF MERGERS

A sample of cash and stock merger transactions consummated between 1975 and 1987 is used to form homogeneous groups based on financial characteristics of both bidding and target firms. The results are used to determine how group heterogeneity with respect to financial characteristics influences intergroup differences in both bidding firm and target firm merger returns. Stockholders of bidding firms with attributes that fit the free cash flow hypothesis of merger motivation suffer wealth losses relative to firms that have characteristics consistent with achievement of scale or scope economies or financial synergies. Differences in target and merger portfolio returns are also found.     

Perceptions of Intentional Wrongdoing and Peer Reporting Behavior Among Registered Nurses

Researchers and practitioners have devoted considerable attention to firms' policies regarding discretionary disclosures. Prior studies argue that firms increase demand for their debt and equity issues and, thus, lower their cost of capital, by providing more informative disclosures. However, empirical research has generally not been able to document significant benefits from increased disclosure.This paper proposes an alternative explanation – firms disclose because it is the socially responsible thing to do. We argue that companies have incentives to engage in stakeholder management by undertaking socially responsible activities and that providing extensive and informative disclosures is one such practice.We examine the relationship between firms' disclosures and measures of social responsibility. We use ratings provided by the Council on Economic Priorities as proxies for the degree of social responsibility adopted by the sample firms. Disclosure rankings provided by the annual Association for Investment Management and Research Corporate Information Committee Reports (AIMR Reports) are used to measure disclosure level.Our results indicate that there is a positive relationship between disclosure level and corporate social responsibility. That is, firms that engage in socially responsive activities provide more informative and/or extensive disclosures than do companies that are less focused on advancing social goals. In addition, we find that socially responsible firms are more likely to provide this increased disclosure through better investor relations practices. These results support our contention that increased disclosure is a form of socially responsible behavior.     

Crisis Management & Team Effectiveness: A Closer Examination

Being able to effectively respond in the event a crisis is relevant to an organization's survival. Whether or not an organization is prepared for a potential crisis depends upon senior officials, and other personnel operating within the company. Corporations with established crisis management teams are able to communicate and effectively respond in the event of a crisis. The purpose of this paper is to suggest effective crisis management depends upon several team-related factors that may influence an organization's response and its ethical responsibility. First, the term crisis is defined, followed by an overview of the differences between crisis communication and crisis management. Second, a review of relevant literature regarding teams and effectiveness is examined. Third, several propositions regarding team effectiveness and crisis management are provided. Finally, ethical concerns in regards to the crisis team and the corporation are reviewed.     

Numerical solutions to an integro-differential parabolic problem arising in the pricing of financial options in a Levy market

We study the numerical solutions for an integro-differential parabolic problem modeling a process with jumps and stochastic volatility in financial mathematics. We present two general algorithms to calculate numerical solutions. The algorithms are implemented in PDE2D, a general-purpose, partial differential equation solver.     

Russian Economic Reform in 1992: The Threat to Stabilization

By the end of 1992, Russia stood at the brink of hyperinflation. This article identifies the main cause as an uncontrolled increase in the money supply related to the budget deficit, and central bank credits to enterprises, and to the rouble zone. These create a vicious inflationary cycle, which will be difficult to break since the political forces representing old Soviet economic structures have undermined stabilization policies. The article concludes that though macro-economic stabilization is not a sufficient condition for the market-oriented transformation of the Russian economy, it remains a necessary one, without which the reform will fail.     

Estimation of the intensity of a Poisson point process by means of nearest neighbor distances

A new unbiased consistent asymptotically normal estimator U _k of the intensity λ of a stationary multivariate Poisson point process is exhibited. This estimate is based on a combination of the j -th nearest neighbor (possibly non Euclidean) distances ( j =1, ..., k ) to a single fixed site x . A simple closed form containing logarithmic terms is obtained for E ( U ^l _k )(0< l < k ).

The Implications of an Organization's Structure on Whistleblowing

Previous studies investigating reports of corporate or individual wrongdoing have failed to examine the effects of an organization's structure upon the decision to blow the whistle. This paper suggests that an organization's structure may perform a significant role in the decision to report versus not report an observed wrongdoing. Five organizational structures (that is, centralized, matrix, horizontal, hybrid, and divisional) were examined in regards to their effectiveness in encouraging or discouraging observers of unethical conduct channels for reporting such behavior. Discussion and implications are provided.
