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

We study the merits of capped retirement products with guarantee for investors who have the flexibility to dynamically adjust their investment strategy. All contracts under consideration are fairly priced such that the net profit of the provider is zero. Without the rider, an expected utility maximizing CRRA investor does not want an investment cap. Here, she commits herself to a strategy a priori. With the flexibility rider, the optimization problem changes and the optimal strategy is a response to an exogenously set price. A fair pricing then anticipates the optimal response of the investor. We show that the maximum expected utility of the investor can, for anticipated fairly priced products, be obtained for a finite cap. Thus, a capped product design can give a Pareto improvement to the otherwise uncapped contract version. 相似文献

1863年,"伦敦大都会铁路"作为世界上第一条地铁开通之时,人们或许不会想到,这种后来被国际公认的"绿色出行"方式所带来的不仅仅是交通的便捷,它正改变着一座座城市的面貌。而对于已经经历了50多年发展历程的中国地铁来说,现在正是"最好的时代"。9月5、6日两天,国家发改委公布了新近批复的25个城市轨道交通建设项目:其中,常州、厦门、兰州、太原、石家庄等城市获准修建地铁,哈尔滨、上海等城市新增或调整城轨的建设方案也获得批准。事实上,发改委并非一夜之间突击批复城轨项目。早在今年5月,常州、厦门、兰州3地轨交规划获批的消息便已见诸报端;太原和石家 相似文献

This paper presents a new and general approach to the theory of irreversible investment. We show that the optimal policy is a base capacity policy and derive general monotone comparative statics results. When the operating profit function is supermodular, the base capacity increases monotonically with the exogenous shock; and firm size is decreasing in the user cost of capital. Last but not least, the paper provides a general existence theorem for optimal policies. 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
