网络口碑信息对消费者购买决策的影响：一个实验研究

本文通过实验法考察了网络口碑信息对消费者购买决策的影响，就网络口碑的影响力在口碑信息类型、传播方向和产品涉入度不同的情况下会表现出哪些差异等问题作了分析。实验结果支持了所提出的6项假设，网络口碑信息对于消费者购买决策的影响力可能会随着口碑传播方向、信息类型以及产品卷入度的不同而呈现出显著差异的预测得到了证实；信息类型、传播方向和产品卷入度之间所存在的交互效应也会明显地作用到网络口碑对消费者购买决策的影响效果。  

网络商品价格搜寻与实证分析

本文以实证的方式研究了网络商品的价格离散程度，证明了由于互联网使信息在市场中呈现均衡分布，成本与价格的透明度被提高，从而网上商品价格也趋于收敛。在完全信息市场上，当信息获取成本极低或为零时，交易者反而减少了从事信息收集的积极性，信息搜寻者的搜寻周期和次数都将减少，决策的速度从而可以加快。网上信息搜寻沿着特定的路径进行，搜寻成本已不再是信息搜寻中最主要的影响因素，市场的成熟情况、网络的传输率等将成为搜寻原则中新的内容。  

Piracy of digital products: A critical review of the theoretical literature

Digital products can be copied at almost no cost and are subject to non-commercial copying by final consumers. Because the copy of a copy typically does not deteriorate in quality, copies can become available on a large scale basis – this can be illustrated by the surge of file-sharing networks. In this paper we provide a critical overview of the theoretical literature that addresses the economic consequences of end-user copying. We analyze basic models of piracy, models with indirect appropriation, models with network effects, and models with asymmetric information. We discuss the applicability of the different modeling strategies to a number of industries such as software, video and computer games, music, and movies.  

面向21世纪的中国网络经济

网络经济作为知识经济的重要组成部分正在迅速成长，成为世界经济增长的新动力。网络经济使得以信息技术为基础的各种服务行业越来越多地成为国家主导产业；世界经济全球化的进程因之大大加速，国际投资、国际以及跨国生产进一步发展，跨国公司和跨国经营借此在世界经济中占据主导地位，企业跨国国家和跨行业联合迅速发展，经济活动将按网络加以重新组织，网络经济发展的现实提醒我们；中国必须加速发展网络经济，否则，以网络经济为核心的信息产业将极有可能成为21世纪中国经济发展的“瓶颈”产业。  

The role of varying risk attitudes in an auction with a buyout option

Summary. An auction with a buyout option is modelled. Such an option allows a bidder to purchase the item being auctioned at a pre-specified buyout price, instead of attempting to obtain the item through the traditional auction procedure. This analysis is motivated by internet auctions where such options are present. If all auction participants are risk neutral, the seller will choose a buyout price high enough so that the option is never exercised. However, a risk averse seller facing risk neutral bidders will choose a price low enough so that the option is exercised with positive probability. Further, if bidders are risk neutral and the seller is risk averse, this option may result in a Pareto improvement compared to a sealed bid second price auction.Received: 3 December 2002, Revised: 28 September 2004, JEL Classification Numbers: D44, L86, D8.

Late and multiple bidding in second price Internet auctions: Theory and evidence concerning different rules for ending an auction

In second price Internet auctions with a fixed end time, such as those on eBay, many bidders submit their bids in the closing minutes or seconds of an auction. We propose an internet auction model, in which very late bids have a positive probability of not being successfully submitted, and show that late bidding in a fixed deadline auction can occur at equilibrium in auctions both with private values and with uncertain, dependent values. Late bidding may also arise out of equilibrium, as a best reply to incremental bidding. However, the strategic advantages of late bidding are severely attenuated in auctions that apply an automatic extension rule such as auctions conducted on Amazon. Field data show that there is more late bidding on eBay than on Amazon, and this difference grows with experience. We also study the incidence of multiple bidding, and its relation to late bidding.  

高校应对大学生网络创业问题的一些理性思考

随着大学生就业形势日益严峻,以创业带动大学生就业成为大势所趋。目前,网络创业投入小,回报快而高;市场潜力无限;加上大学生自身的智力优势,使得网络创业成为大学生创业的新途径和新模式。但是大学生的网络创业也并非一帆风顺,由于网络创业意识薄弱,对创业缺乏理性认识;缺乏创业者心态,创业技能落后;创业范围局限性大;缺乏资金支持和管理意识;技术发展后劲不足,加上创新意识缺乏,导致发展潜力不济等等,成为制约和困扰大学生网络创业的重要因素。针对这些问题,本文提出了新时期高校如何应对的一些思考和建议,主要包括：将大学生网络创业作为系统工程来对待;重视强化创业师资培养;积极推进理性和独立自主的创业文化环境的建设;反思和改革高等教育改革等。
