Investing and consuming may not be so different as traditional economic theory has understood them. The consumer research literature has begun to view consumption not simply as rational decisionmaking, but as a more multisensory activity in which emotion and fantasy play important, if not essential, roles. This new perspective has been extended by Holt (1995) in a matrix of metaphors in which consumption can be viewed as an interaction with objects and/or other persons as an end in itself and/or a means toward toward other ends. This paper theorizes how this matrix might apply to investment and uses a literary analysis of the best-selling The Motley Fool Investment Guide to examine whether or not our knowledge of consumers might in this way inform our understanding of investors. 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

中国海域、海岛开发现状
由于海洋环境的特殊性,海洋不是人类的居住环境,人们总觉得海洋开发离自己比较遥远,企业对海洋资源开发与利用也不知如何下手.但随着国际上对海洋资源的一些开发新案例相继出现,中国对海洋资源的开发利用也呈现多样化的趋势.比如一些国家正在研发水下房屋建设,迪拜已推出了水下别墅项目,各种海上游乐设施和海上运动项目已被人民广泛接受,海洋的开发类型越来越多,不但有传统的海洋产业在蓬勃发展,而且又在不断产生新的海洋产业. 相似文献

Studies conducted in the past have identified inefficiencies in the market for Closed-End Investment Company (CEIC) shares. In addition, studies have demonstrated the potential for trading strategies to exploit these inefficiencies. The purpose of this paper is to investigate the possibility of achieving excess returns through the utilization of relatively simple strategies not requiring continuous monitoring of discount(s) or frequent trading. Our investigation demonstrates that realizing excess returns through the use of simple mechanical trading strategies will not be possible. 相似文献

A deep-ingrained doctrine in asset pricing says that if an empirical characteristic-return relation is consistent with investor “rationality,” the relation must be “explained” by a risk (factor) model. The investment approach questions the doctrine. Factors formed on characteristics are not necessarily risk factors; characteristics-based factor models are linear approximations of firm-level investment returns. The evidence that characteristics dominate covariances in horse races does not necessarily mean mispricing; measurement errors in covariances are likely to blame. Most important, risks do not “determine” expected returns; the investment approach is no more and no less “causal” than the consumption approach in “explaining” anomalies. 相似文献
