This study focuses explicitly on the methodological implications of the endogenous theory of governance as applied to firm performance. In particular, if firms choose their governance structures as part of a constrained performance maximization process, then application of an appropriate empirical methodology should reveal statistical evidence of such behavior. In this study we take advantage of the endogenous switching regression model framework to determine whether such predicted optimizing behavior can be corroborated by the data. The model allows us to test explicitly for selection behavior in accordance with comparative advantage and, concomitantly, the presence of selectivity bias, in estimating the impact of CEO duality on firm performance. The selection and performance equations are modeled in accordance with the extant accounting, economics, and management literature on the impact of the dual governance structure on firm performance. Overall, we tested four performance measures for the entire sample of firm‐year observations as well as for the largest three industries in terms of sample sizes. The major finding, robust in all cases, is that there is no evidence to support a contention that CEO duality is a structure purposefully chosen for optimizing performance. If firms are indeed choosing the dual leadership structure, they are doing so for reasons other than improving performance from what it would be otherwise. In fact, for performance measured as market return and earnings per share, there is evidence of a significant selectivity bias that acts to lower performance below what it would have been under random assignment. For performance measured by Tobin's q and return on assets, we found neither evidence of selectivity bias, nor any significant marginal performance impacts of CEO duality. Such findings are inconsistent with an endogenous governance theory, at least when applied to firm performance. Copyright © 2009 John Wiley & Sons, Ltd.  相似文献

We show that information complementarities play an important role in the spillover of transparency shocks. We exploit the revelation of financial misconduct by S&P 500 firms, and in a “Stacked Difference-in-Differences” design, find that the implied cost of capital increases for “close” industry peers of the fraudulent firms relative to “distant” industry peers. The spillover effect is particularly strong when the close peers and the fraudulent firm share common analyst coverage and common institutional ownership, which have been shown to be powerful proxies for fundamental linkages and information complementarities. We provide evidence that increase in the cost of capital of peer firms is due, at least in part, to “beta shocks.” Disclosure by close peers—especially those with co-coverage and co-ownership links—also increases following fraud revelation. Although disclosure remains high in the following years, the cost of equity starts to decrease.  相似文献

The purpose of this paper is to evaluate the board roles that make a board effective in the performance of adopting corporate social responsibility (CSR) practices. This paper examines directors' perceptions of the three main roles: monitoring, service, and strategic, which provide tools for critically understanding how the board adds the value in moving the organization towards more CSR practices. The stakeholder theory is used to distinguish the influence of the three main roles on the adoption of CSR practices. Primary data were collected for this research by conducting structured questionnaires with a sample of 461 directors from Saudi listed companies for study purpose. The results show that an appropriate mix of directors' roles and the development of sound board monitoring and service roles are the most crucial determinants of CSR adoption in Saudi listed companies. As the extant corporate governance and CSR literatures do not provide a clear perspective with contradictory outcomes about board roles in influencing CSR practices, the originality of this research is its contribution by evaluating the directors' perceptions of developing a direct relationship between the board roles and the adoption of CSR practices. Furthermore, the use of the stakeholder theory provides additional insights into identifying the most influential board role factors enhancing stakeholders' expectations of CSR practices.  相似文献

This study describes the creation and validation of a multidimensional model which assesses the level of employee satisfaction based on international theoretical models. It utilizes data collected from a sample of 518 public and private company employees during the year 2009 in the city/state of São Paulo, Brazil. In the first stage of the study, 15 independent dimensions were theoretically obtained. In the second stage, five different multiple dimensions were confirmed using structure equation modeling (SEM) technique, thus characterizing general configurations of the organizational climate construct denominated motivation, management philosophy, leadership, people management and nature of work. It is hoped that the model can contribute by enhancing managerial best practices of an organization by attending a major demand for those listed on stock markets, since these companies must periodically provide information on job satisfaction of their employees to maintain or achieve higher levels of corporate governance.  相似文献

Following the waves of corporate scandals and the increasing attention to corporate governance, the transparency of reporting on director-level pay has increased across Europe. This article examines the extent of convergence in laws, codes and corporate reporting practices in regard to director-level pay in France, Germany, Switzerland and the UK. The paper analyses annual reports and the websites of 23 companies, using institutional theory to discuss the coercive, normative and mimetic pressures for convergence that are revealed, not just in the laws and codes in each country, but also in the standardized wording in the relevant sections of reports which have become clichés.  相似文献

行为金融学目前已逐渐成为金融学研究中的一个重要领域,在它的影响下,公司财务领域内也形成了行为公司财务的研究范式。与经典的公司财务理论相比,行为公司财务引入了行为因素的影响,它认为外部市场的非有效性和内部管理者的非理性影响着公司的财务决策和公司价值最大化的行为。文章简单总结了行为公司财务的最新研究进展,也就是市场的非有效性和管理者的非理性对公司的融资政策、投资政策、股利政策和并购行为等各方面的影响。针对目前我国资本市场的非有效性,文章认为在我国上市公司的财务研究中应该引入行为公司财务的理论范式和研究方法,才能使得研究前提和结果符合我国的实际经济情况。  相似文献

This study draws from the corporate governance literature to investigate the implications of board involvement for international joint ventures (IJVs). We extend recent corporate governance research on the value of board involvement by investigating unique sources of complexity related to the nature of the IJV. We argue and find that board involvement can enhance the performance of IJVs, particularly for collaborations that are complex in nature due to their broad functional scope as well the level of market overlap between IJV parents. We complement recent research on joint venture control that has focused on the antecedents and types of control, as well as studies on formal (e.g. contractual safeguards and monitoring) and informal governance mechanisms (e.g. trust) by providing empirical evidence that IJV board involvement is valuable when directors undertake their control and coordination responsibilities. We advance corporate governance research by providing evidence that joint ventures possess several unique characteristics that shape the value of board involvement, thereby showing that applications of corporate governance theory to joint ventures are useful, but should be made with care.  相似文献
