PORTFOLIO CHOICE VIA QUANTILES

A portfolio choice model in continuous time is formulated for both complete and incomplete markets, where the quantile function of the terminal cash flow, instead of the cash flow itself, is taken as the decision variable. This formulation covers a wide body of existing and new models with law‐invariant preference measures, including expected utility maximization, mean–variance, goal reaching, Yaari's dual model, Lopes' SP/A model, behavioral model under prospect theory, as well as those explicitly involving VaR and CVaR in objectives and/or constraints. A solution scheme to this quantile model is proposed, and then demonstrated by solving analytically the goal‐reaching model and Yaari's dual model. A general property derived for the quantile model is that the optimal terminal payment is anticomonotonic with the pricing kernel (or with the minimal pricing kernel in the case of an incomplete market if the investment opportunity set is deterministic). As a consequence, the mutual fund theorem still holds in a market where rational and irrational agents co‐exist.     

企业购并中的财务问题探析

上个世纪80年代美国曾经出现所谓的＂购并风＂,在90年代形成愈演愈烈之势。近年来,随着我国社会主义市场经济体制的逐步发展和加入世界贸易组织,我国企业购并现象日益突出。对于企业购并中政府过分干预的问题,应实行政企分离,明确产权;对于企业购并中的财务风险,企业应积极应对并寻找解决之道;对于购并后的整合,企业应予以重视。     

Electronic Commerce Encourages Differentiation

Abstract

This paper explores why and how ecommerce firms differentiate their products and services. Consumers who shop online are able to do quick and easy comparison shopping, including shopping in an active market for used goods. Since online product search and price comparisons are faster, easier, and involve fewer shopping costs, firms who sell online must differentiate their products and services to a greater extent than those who do not sell online. These product and service differentiations may be certified and rated by host shopping sites and by outside ratings companies.     

A preliminary comparative analysis of 3D body scanner,manually taken girth body measurements and size chart measurements

In an attempt to provide a technological solution to the influx of cheap imports in South Africa and bridging the technology divide between Africa and the rest of the world, the Council for Scientific and Industrial Research procured a three‐dimensional body scanner from the Textile and Clothing Technology Corporation, in the US. The pilot study was aimed at introducing the technology to the South African consumers, and to compare the scanned data with the manually taken measurements. A convenience sample of 56 females in South Africa was interviewed using a structured questionnaire. Interviews were used to capture views on acceptance of the technology, prior to being scanned. Scanning garments made from a stretchy fabric were designed and sewn in four sizes of small, medium, large and extra large. A covariance, one sample t‐test and paired t‐ tests were used for data analyses. Almost all respondents felt comfortable with the designed scanning garments and the scanning process. The scanner measurements were generally more numerical in value than the manual measurements for a body part as expected, although the disparity was on the higher side than expected. The discernible difference between means of scanned data and standard values in the currently used sizing charts highlighted the long overdue need to update the sizing charts using a national anthropometric database generated locally.     

Investment and Innovation State Support of Agriculture in Russia as a Condition of WTO

Russian agriculture is one of the industries operating in the unstable economic situation in a developing market taking into account risks of the world economy, economic, political, and climatic factors. The role of agriculture is to provide people＇s needs for food, significant effects on employment, the efficiency of domestic production, and way of life in rural areas by obligatory preserving food security in Russia. One of the major tasks for agriculture is the development of innovations and investments aimed at improving the competitiveness of the domestic agricultural sector. Russia＇s membership in the WTO since 2012 is getting a particular importance in the innovation and investment support of agriculture. The strategy of innovative development of the Russian Federation until 2020 ＂Innovative Russia--2020＂ assumes three possible options for innovative development： inertial （directed on imports）, catch-up development and a local technological competitiveness and a variant of achieving leadership in leading scientific and technical sectors, and fundamental research. A positive point is that the strategy provides an algorithm of state support of the innovation cycle. The innovation cycle is the process associated with the sequence of innovation transformations （scientific or business ideas） in products, technology, business process and launches it on the market for commercial use. A positively developing regional aspect is of great importance.

制度的博弈论解释批判——基于现实行路规则复杂多样性的分析

主流观点认为,制度是博弈过程中参与人的均衡策略,但对避免相向碰撞的行路规则的考察发现,现实中经济行为者采纳的惯例化规则远较制度的均衡策略论揭示的复杂多样。制度博弈均衡策略论的这种不充足解释力不仅仅是因为现有的制度博弈模型忽略了一些现实的基本行为策略,也因为博弈论框架只是一个有关社会交互问题的部分性分析框架,并不能覆盖所有的解决社会交互问题的方法。一个统一性的制度解释框架宜放弃博弈论的分析思路,更多地考虑制度的互补性问题。     

Master's Level Education in Business Marketing: Quo Vadis?

ABSTRACT

Given the paucity of knowledge on the state of business marketing education at the master's level, we conducted an exploratory survey of instructors at selected universities in North America and Europe. We supplemented results from this survey with discussions with our colleagues who teach business marketing at the master's level, and a review of articles on master's level programs.

Through our investigations, we discovered that there is a shortage of management cases that address contemporary issues in business marketing. We learned that nearly half of survey participants do not use a textbook and that the remaining participants use a wide variety of textbooks. We observed that many instructors still teach business marketing courses from a traditional functional perspective. Instead, we believe that business marketing courses must address a host of emerging issues such as value and its assessment, business process reengineering, global marketing, working relationships and business networks, and cross-functional coordination issues, among other things.

We believe that scholars can rejuvenate the discipline by tailoring business marketing courses to the new generation of accelerated master's programs, by creating a network for sharing information on new cases and teaching materials, and by writing more relevant and timely business marketing cases. Finally, we believe that the time is right for a faculty consortium on teaching business marketing.     

Modeling e-loyalty: a moderated-mediation model

ABSTRACT

This work proposes a research model that elaborates upon the development of e-loyalty based on the signaling theory and attachment theory. In the model, e-loyalty is indirectly related to both visual appeal and an e-tailer’s service reputation through the full mediation of trust and affection. At the same time, the relationships between trust and e-loyalty and between affection and e-loyalty are hypothetically moderated by an e-tailer’s service reputation. The proposed hypotheses of this research were empirically tested using data from working professionals in high-tech firms in terms of online retailing. This study surveyed the same research participants at two different time points, one month apart, to verify the theoretical inferences. The empirical findings herein complement the previous literature by presenting how visual appeal and an e-tailer’s service reputation simultaneously influence e-loyalty through various mediating and moderating mechanisms.
