In about one-third of US IPOs between 1996 and 2000, executives received stock options with an exercise price equal to the IPO offer price rather than a market-determined price. Among firms with such “IPO options”, 58% of top executives realize a net benefit from underpricing: the gain from the options exceeds the loss from the dilution of their pre-IPO shareholdings. If executives can influence either the IPO offer price or the timing and terms of their stock option grants, there should be a positive relation between IPO option grants and underpricing. We find no evidence of such a relation. Our results contrast sharply with the emerging literature on managerial self-dealing at shareholder expense. 相似文献

This study demonstrates that in contrast to prior research findings on short-term stock returns, long-term stock returns are
positively correlated with inflation. In addition, within the context of a more complete explanatory model, long-term stock
returns are found to be negatively related to changes in long-term interest rates and negatively related to beginning price
to earnings ratios. The significance of these variables in explaining almost all the time series variation in long-term stock
returns demonstrates that changes in stock values are well explained by theory. 相似文献

A great deal of research has focused on workforce diversity. Despite an increasing number of studies, few consistent conclusions have yet to be reached about the antecedents and outcomes of diversity. Likewise, research on different dimensions of diversity (e.g., age, race, gender, sexual orientation, disability, and culture) has mostly evolved independently. Therefore, the purpose of this review is to examine each of these dimensions of diversity to describe common themes across dimensions and to develop an integrative model of diversity. 相似文献

Since its original development by Sharpe (1964), the Capital Asset Pricing Model (CAPM) has been the focus of great interest, practical usage, modifications, testing, and controversy. The basic hypothesis of the CAPM is that the minimum expected return required by investors on any asset will equal the risk-free rate plus a premium for the asset's contribution to the variance risk of a diversified portfolio as measured by the asset's beta. The model is often utilized by investors to calculate the relevant risk and required return on an asset, while corporate officers widely employ the theory to compute the appropriate discount rate to use in estimating the net present value of capital budgeting projects when evaluating spending decisions (Gitman and Mercurio, 1982). 相似文献

Disaster relief presents many unique logistics challenges, with problems including damaged transportation infrastructure, limited communication, and coordination of multiple agents. Central to disaster relief logistics is the distribution of life-saving commodities to beneficiaries. Operations research models have potential to help relief agencies save lives and money, maintain standards of humanitarianism and fairness and maximize the use of limited resources amid post-disaster chaos. Through interviews with aid organizations, reviews of their publications, and a literature review of operations research models in transportation of relief goods, this paper provides an analysis of the use of such models from the perspective of both practitioners and academics. With the complexity of disaster relief distribution and the relatively small number of journal articles written on it, this is an area with potential for helping relief organizations and for tremendous growth in operations research. 相似文献

This study explores the ability of career satisfaction to mediate the relationship between corporate ethical values and altruism.
Using a sample of individuals employed in a four-campus, regional health science center, it was determined that individual
career satisfaction fully mediated the positive relationship between perceptions of corporate ethical values and self-reported
altruism. The findings imply that companies dedicating attention to positive corporate ethical values can enhance employee
attitudes and altruistic behaviors, especially when individuals experience a high degree of career satisfaction. 相似文献

South Africa's first build‐own‐operate‐transfer (BOOT) project for municipal services was signed in late December 1998 by the city of Durban and a private project company associated with French conglomerate Vivendi. The project will treat waste water for sale to industrial customers who would otherwise use more expensive potable water in their manufacturing processes. The project structure, with its multiple contracts and supporting agreements, guarantees and complex shareholding relationships, represents a sophisticated analytical challenge for lenders, whose financing will ultimately be at risk in the deal. Development finance institutions, such as the Development Bank of Southern Africa (DBSA), must review such projects in even greater detail because of their mandate to promote sustainable infrastructure development in the region. This article presents the DBSA ‘s analytical perspective on the Durban BOOT project in an effort to capture the complex, innovative and strongly developmental character of what, for South Africa, is a ground‐breaking public‐private partnership project. 相似文献

This paper addresses a problem which is at the forefront of educational debate in the Southern African economy. It attempts to set out the nature and processes of evaluators and the qualities necessary in evaluators if their task is to be accomplished with integrity. The article could be used to draw up basic guidelines that may be regarded as prerequisites for evaluating educational programmes in this country and promotes evaluation as a powerful means of refining educational programmes while they are in operation. 相似文献

An analysis of efficiency in the delivery of financial services: The case of life insurance agencies 总被引:2,自引:0,他引:2
Scale and scope economies are examined for life insurance agencies that distribute multiple financial products. The results of this study suggest that there are significant administrative returns to scale for firms that sell a mix of financial products. The findings for scope estimates are inconsistent, suggesting that there are positive and negative cost complementaries for pairs of products. Subadditivity can be rejected, suggesting that joint distribution of financial products is not necessarily more efficient than specialization and that different-sized agencies are not necessarily at a cost disadvantage. 相似文献
