Cost information sharing with uncertainty averse firms

Summary. A homogeneous Cournot duopoly with asymmetric information is analyzed. Every firm learns its own marginal cost parameter, but not the marginal cost parameter of the opponent. Every firm can commit to revealing its private information to the other firm, i.e. to share information. The influence of uncertainty aversion on the readiness of the duopolists to share cost information is analyzed. Uncertainty aversion is modeled according to the Choquet utility theory. It is shown that low uncertainty aversion leads the firms to share information, while high uncertainty aversion leads the firms not to share. A simple economic explanation for this result is given.Received: 5 January 2001, Revised: 7 May 2003, JEL Classification Numbers: D43, D81, D82.I wish to thank Jürgen Eichberger, Volker Krätschmer, Willy Spanjers, seminar participants at Universität des Saarlandes, seminar participants at University College London, participants in the conference of the Verein für Socialpolitik in Mainz 1999 and an anonymous referee for helpful comments.

Optimal risk sharing with non-monotone monetary functionals

We consider the problem of sharing pooled risks among n economic agents endowed with non-necessarily monotone monetary functionals. In this framework, results of characterization and existence of optimal solutions are easily obtained as extensions from the convex risk measures setting. Moreover, the introduction of the best monotone approximation of non-monotone functionals allows us to compare the original problem with the one which involves only ad hoc monotone criteria. The explicit calculation of optimal risk sharing rules is provided for particular cases, when agents are endowed with well-known preference relations.      

美国税权划分制度评析与借鉴

美国的联邦、州和地方三级政府各自拥有属于本级的税权,并在同级政府层面上表现为税收立法权、执法权和司法权三者之间的划分与制衡。本文通过分析美国税权划分的主要特点,对我国税权划分改革提出了若干建议:确定税权划分的法定主义原则、税收立法权划分的指导思想、赋予地方适度税权的具体设想、明确划分中央与地方税收执法权限、建立解决地区间税权争议的协调机制、通过一些制度设计完善税收司法权的行使。     

适当下放地方税立法权完善税收立法体制

当前中央和地方税收立法权划分中存在一些问题和矛盾。要化解这些矛盾、解决这些问题,需要在借鉴历史和国外经验的基础上,区别不同的地方税税种,分层次、有限度、可控制地下放部分税收立法权,完善税收立法体制,健全分税制财政管理体制以至整个财税体制。

The social value of income information in a model with market power and endogenous variety

The present paper analyzes the value of public information in a general equilibrium economy with imperfect competition. The welfare effects of an improved information system for perfectly competitive economies have been extensively investigated in the published literature. Schlee (2001) shows that the value of information is always negative in exchange economies if an efficient risk sharing mechanism exists. In contrast, in economies with production, better information reduces welfare provided consumers are sufficiently risk-averse ( Eckwert and Zilcha 2000, 2003 ). In the present paper it will be shown that this result is robust if the production sector exhibits monopolistic competition in the Chamberlinian sense. Even so, the inefficiency of equilibria adds further potential for positive welfare effects of improved information. A model is presented where the degree of market imperfection is positively linked to the value of information. If the markup on competitive prices is sufficiently high, the value of information is positive; that is, better information increases economic welfare.

Practicing effective knowledge sharing in international hotel joint ventures

Knowledge sharing can be described as the process by which individuals mutually exchange their knowledge and collaboratively generate new knowledge. Since international hotel joint venture partners typically possess skills in competing areas, this process of knowledge sharing is critical to the success of these alliances. Therefore, this article presents a framework that can be used to foster effective knowledge sharing at the individual joint venture manager level, at the relationship level between individuals, and across the entire organization.
