也许对于所有的工业化国家来说,公司治理问题都是一个热点讨论问题。具体到学术圈和商业圈,讨论的焦点主要落在如何能够提高董事会对公司经理监管的政策和程序上,目前关于全球公司治理观点的主要分歧是公司的基本目标。除了该问题本身的复杂性之外,分歧的原因主要在于讨论的结果可能影响到各个观点冲突方的自身利益。 相似文献

In this paper, we generalize recursive utility to include lifetime uncertainty and utility from bequest. The generalization applies to discrete-time as well as continuous-time recursive utility, and it is an important step forward in the development of recursive utility. We formalize the problem of optimal consumption, investment, and life insurance choice under recursive utility, and we state a verification theorem with a generalized Hamilton-Jacobi-Bellman equation. Our generalization of recursive utility allows us to study optimal consumption, investment, and life insurance choice under separation of (market) risk aversion, elasticity of inter-temporal substitution, and elasticity of substitution between bequest and future utility. The separation gives rise to hump-shaped consumption patterns as observed in realized consumption. 相似文献

In the classical portfolio optimization problem considered by Merton, the resulting constant proportion investment plan requires a diffusive trading strategy. This means that, within any arbitrarily small time interval, the investor must impractically both buy and sell stocks. We study the problems of a mean-square and a power utility investor for whom the trading strategy is constrained to be smooth, i.e. nondiffusive. This means that over sufficiently small time intervals, the investor is either a seller or a buyer of stocks. The mathematical framework is built around quadratic objectives such that trading activity is punished quadratically. Mean-square utility is quadratic, and power utility is covered by quadratic punishment of distance to Merton’s power utility portfolio. We present semi-explicit solutions and, in a series of numerical illustrations, show the impact of trading constraints on the portfolio decision over the investment horizon. 相似文献

Abstract: We investigate the effects of the introduction of Statement of Financial Accounting Standards No. 131 (SFAS 131) on the market's valuation of foreign earnings. Thomas (1999) documents that investors discount the value of foreign earnings for US multinational companies. He conjectures but does not test the possibility that this finding is due to poor disclosure related to foreign operations. We find strong evidence that the introduction of the standard is positively associated with the pricing of foreign earnings. In addition, we use both the Mishkin (1983) test and a zero-investment hedge portfolio test and find that investors' mispricing of foreign earnings lessens (and in fact disappears) after SFAS 131. This study is one of the first attempts to show that improved disclosure reduces mispricing. 相似文献

Internet impacts on supply chain management 总被引:1,自引:0,他引:1

The traditional way of managing supply chains has changed dramatically over the last 5 years. Face-to-face management, manual tracking systems, paper-dominated order processing systems, and wired communication links were the primary management tools available to logistics managers. Today, they are obsolete. The article provides an overview of some of the new tools and trends discussed in this issue, including website structure, e-purchasing, electronic marketplaces, building vendor relationships, and the use of the Internet in managing supply chains in China. 相似文献
