基于资产风险信息不对称的可转债融资信号模型

主要研究了可转债与资产风险信息不对称的信号模型,通过引入信息透明度,成本等因素进一步拓展了Brennan和Kraus(1987)提出的无成本可转债融资信号模型,说明使用可转债融资有助于克服资产风险的信息不对称问题,并能提高融资效率,减少债务融资成本。

Entrepreneurial competition and its impact on the aggregate economy

This paper models entrepreneurship as the entrepreneur’s information processing activity in order to predict changes in demand and reallocate resources. The results show that allocative efficiency—and therefore aggregate productivity—increases through intensified competition by entrepreneurs grasping at opportunities. This fierce competition leads to price reductions that result in the improvement of measured aggregate productivity. The price reduction also forces relatively less able entrepreneurs to become workers. As resources are then dealt with only by relatively talented entrepreneurs, this selection effect also increases aggregate productivity. The paper also discusses how the selection effect influences the distribution of firm size.      

Technological Innovation and Its Impact on Business Model, Organization and Corporate Culture – IBM’s Transformation into a Globally Integrated, Service-Oriented Enterprise

This article investigates the influence of information and communication technology (ICT) on business transformation. First, the general, ICT-driven development lines of globalization and service-orientation are described. Then, an analysis of the IBM Corporation’s transformation over the past 50 years into a globally integrated, service-oriented company illustrates that ICT innovations must be dealt with by simultaneous adaptation of business model, organization and corporate culture. For many companies the ability to manage this change becomes increasingly critical.

基于二维权变模型的农村信息化发展动力研究

信息化是我国新农村建设的重要内容。由于经济基础与社会环境的差异。农村信息化建设不能一刀切,需要根据实际情况制定切合自身发展的道路。从权变模型及发展动力模式的角度对农村信息化进行了较为全面的思考。根据环境维度中的村民素质和农村信息化基础设施状况两个维度提出了农村信息化发展动力模式权变模型,定义了该模型的内涵,阐述了发展模式的演变途径及该模型的使用方法,对我国农村信息化的建设提出了一些建议。     

Re-matching, information and sequencing effects in posted offer markets

This paper evaluates the effects of some standard procedural variations on outcomes in posted offer oligopoly experiments. Variations studied include the presence or absence of market information, the use of re-matched or fixed seller pairs and alterations in the order of sequencing. Experimental results indicate that such variations can have first order effects on outcomes. For this reason, we recommend that results in oligopoly experiments be carefully interpreted in light of the procedures selected.

我国电话营销的法律风险及其规制

电话营销源于美国,它在我国刚起步,是一个新兴产业。在营销学上电话营销被归类为直效营销的一种营销方式。在法学领域可理解为商业活动者以电话为主要媒介,从事商业性质的商品或服务的推销行为。以最具代表性的保险电话营销为例,电话营销的法律风险包括：举证风险、说明义务风险、自动续保风险、扣取保费风险。同时,电话营销的不规范导致了侵害消费者合法权益的行为层出不穷,这些非法行为急需法律的规制,而最为行之有效的策略就是加快《个人信息保护法》的立法及其相关配套法律法规的制定与颁布。     

完善金融业机构信息管理的建议

为保障金融体系稳健运行,防范系统性金融风险,人民银行自2009年开始进行了一系列规范和加强金融业机构信息管理工作,开发并建立了“金融业机构信息化管理系统”,为推进我国金融标准化建设、实现金融体系内信息共享奠定了基础。系统运行两年后,相关工作有待进一步完善。     

Volume,volatility and information linkages in the stock and option markets

This paper examines the relationship between option trading activity and stock market volatility. Although the option market is uniquely suited for trading on volatility information, there is little analysis on how trading activity in this market is linked to stock price volatility. The bulk of the discussion tends to focus on whether trading activity in the stock market is informative about stock volatility. To analyze the information in option trading activity for stock market volatility, a sample of 15 stocks with the highest option trading volume is selected. For each stock, it is noted that the trading activities in the put and call option markets have significant explanatory power for stock market volatility. In addition, the results indicate that the call option trading activity has a stronger impact on stock volatility compared with that of the put options. Our results demonstrate that information and sentiment in the option market is useful for the estimation of stock market volatility. Also, the significance of the effects of option trading activity on stock price volatility is observed to be comparable to that of stock market trading activity. Furthermore, the persistence and asymmetric effects in the volatility of some stocks tend to disappear once option trading activity is taken into account.     

我国劝诱性医疗的成因:管制、市场结构还是信息不对称?

本文使用一个价格管制背景下的医疗信号博弈模型讨论了我国劝诱性医疗现象的成因,以及管制、市场结构和信息不对称在导致资源配置扭曲中的作用机制和相互关系。研究表明,在无管制市场中,医生存在以价格承诺实现医疗资源最优配置的动机和可能。在政府对各项医疗收费实施全面价格管制的制度背景下,过低的诊断价格上限将使市场自发的事前价格承诺机制失灵,并诱发欺骗性的诊断结果,而药品和医疗器械使用的价格上限管制则诱使医生以增加药品和医疗器械使用量的数量决策来维持自身的垄断抽租能力。这两种机制的共同作用最终导致了双重劝诱性医疗均衡。在此均衡下,由于公立医院的垄断地位未受影响,故价格管制无法改善患者的福利状况,反而会导致社会的净福利损失。
