软件产品价格形成机理的经济学求解--基于广义价格理论视角

软件产品是具有公共性、外部性和网络性等特征的"混合品",其经济性质与物质产品有较大差异,传统价格机制理论无法合理解释其成本价值与使用价值以至其价格的形成。必须引入新的价值评价指标,对软件产品的成本价值与使用价值进行新求解,把广义价格机制理论的产权契约均衡价格决定论与成本价值和使用价值边际均衡论结合起来,从"谈判力"均衡角度研究软件产品价格形成机理。

虚拟水及其在缓解区域水资源短缺中的应用研究

虚拟水是指生产商品和服务所需要的水资源数量。虚拟水战略是指贫水国家或地区通过贸易的方式从富水国家或地区购买水密集型农产品(粮食)来获得本地区水和粮食的安全。本文在综述前人对虚拟水研究的基础上,计算了2002年甘肃省及不同地区主要农产品虚拟水含量,并对甘肃省加强虚拟水贸易的战略进行了探讨。

An analysis of the process generating de facto standards in the PC spreadsheet software market

This paper develops a model to analyze the emergence of de facto or market defined compatibility standards in the market for PC spreadsheet software over the period 1982–1988. The model is capable of integrating diverse fragments of empirical evidence and a number of important theoretical building blocks, in particular the analysis of gateways between different versions of the same package, product preannouncements, and diverse consumer tastes towards intrinsic quality and network externalities. The model also explores the implications of different functional forms for the relationship between installed base and the value of network externalities. The paper finds that at least some enhancements to the basic model of standards have to be incorporated to offer a reasonable approximation to developments in the PC spreadsheet software market. The simplest model of de facto standards is not able to describe developments in this market.     

论实业投资与虚拟投资的关系

企业投资按照性态可划分为实业投资和虚拟投资,二者对企业经济发展能够起到“双轨驱动”效应。为了有效发挥实业投资和虚拟投资对提高企业绩效的作用,笔者以实业投资和虚拟投资的内涵为研究的基点,对实业投资与虚拟投资的统一性、背离性关系进行了深入探讨,并提出了协调实业投资与虚拟投资关系的有效措施。     

Price discrimination and efficient matching

This paper considers the problem of a monopoly matchmaker that uses a schedule of entrance fees to sort different types of agents on the two sides of a matching market into exclusive meeting places, where agents randomly form pairwise matches. We make the standard assumption that the match value function exhibits complementarities, so that matching types at equal percentiles maximizes total match value and is efficient. We provide necessary conditions and sufficient conditions for the revenue-maximizing sorting to be efficient. These conditions require the match value function, modified to incorporate the incentive cost of eliciting private type information, to exhibit complementarities in types.JEL Clalssification Numbers C7, D4We thank Jonathan Levin, Tracy Lewis, and the seminar audience at University of California at Los Angeles, University of British Columbia, Duke University, and 2003 Econometric Society North American Summer Meeting for comments and suggestions.
