产品市场竞争与代理成本

通过构造以Hotelling价格竞争模型为基础的多阶段博弈模型,首先分别分析了在信息对称与信息不对称情况下管理者的努力程度与所有者激励管理者存在的代理成本,然后讨论了在信息不对称情况下外部产品市场的竞争程度对于代理成本的影响。通过分析我们认为外部产品市场竞争程度越高,代理成本越低,外部产品市场能够成为一项促进公司治理绩效的工具。     

信息不对称与电子商务的发展

本文认为,信息不对称引致的信用缺失是制约电子商务发展的重要因素,发展我国电子商务除了继续加强基础设施建设外,建立和完善社会信用体系,提高信用度是必不可少的重要方面。文章提出,要建立良好的信息沟通渠道和机制,使信息公众化、公开化;提高企业组织化程度;制定企业信用评价制度:健全法制,约束企业交易行为,提高其信用度;消除信息不对称,促进我国电子商务健康发展。

信息时代组织协调新特点研究

今天所发生的信息技术革命,不是由生产的变化驱动的,而是由协调的变化驱动的。所以必须分析和了解集中化与分权化的矛盾、信息技术对组织结构的影响、不同环境对协调的影响、组织协调的阻碍因素、规范价值和组织文化的协调、从上级协调到团队协调的特点。     

面向信息集成的企业信息管理

企业决策所面临的信息孤岛问题已成为现代信息管理的瓶颈,从而引出信息集成技术理念。但单从技术角度来进行信息集成,并不能解决问题。信息集成是一个系统化过程,除了要依靠技术外,还要有相应的组织结构和人力资源的配置管理,它实际上是一个深入的企业信息管理问题。

Multi-lateral trade negotiations and the Most Favored Nation clause

This paper considers the interaction between private information and the Most Favored Nation clause in trade negotiations. It demonstrates that by aggregating uncertainty over a number of trading partners, the Most Favored Nation clause may offer a welfare improvement over a set of bilateral trade negotiations. This improvement is shown to be most pronounced when a large number of countries are involved in negotiations.     

Modeling the effects of including/excluding attributes in choice experiments on systematic and random components

This paper examines the impact of attribute presence/absence in choice experiments using covariance heterogeneity models and random coefficient models. Results show that attribute presence/absence impacts both mean utility (systematic components) and choice variability (random components). Biased mean effects can occur by not accounting for choice variability. Further, even if one accounts for choice variability, attribute effects can differ because of attribute presence/absence. Managers who use choice experiments to study product changes or new variants should be cautious about excluding potentially essential attributes. Although including more relevant attributes increases choice variability, it also reduces bias.     

The Role of the Global Reporting Initiative's Sustainability Reporting Guidelines in the Social Screening of Investments

Social screening of investments calls not only for investment policy and criteria, but also for information about companies, their policies, practices and performance. The Global Reporting Initiative (GRI) and its June 2000 Sustainability Reporting Guidelines have the potential to significantly improve the usefulness and quality of information reported by companies about their environmental, social and economic impacts and performance. The GRI aims to develop a voluntary reporting framework that will elevate sustainability reporting practices to a level equivalent to that of financial reporting in rigour, comparability, auditability and general acceptance. This will be a welcome and efficient supplement to the questionnaires, interviews, press releases, media reports and other sources of information traditionally used for screening in investment decision making – social/ethical and mainstream. The Dow Jones Sustainability Group Index, the Jantzi Social Index and the Innovest EcoValue'21 analytical platform, together with the SRI community, are all likely to benefit from GRI-style sustainability reports. One of the GRI's key challenges is to accommodate the broad variety of disclosure needs and expectations of a wide range of report users and company stakeholders. To maximize the usefulness of the GRI Guidelines, report users, including the SRI community, need to be engaged in the process of developing and refining the Guidelines over time. The GRI Guidelines are emerging as an important instrument in enabling companies to communicate with their stakeholders about performance and accountability beyond just the financial bottom line.     

Advertising effects on consumer welfare: Prices paid and liking for brands selected

The effect of advertising on consumer welfare has been the subject of dispute among economists, arising largely from disagreement among scholars regarding the persuasive versus the informative role of advertising. This paper reports two experiments that explore the welfare implications of advertising effects. Experiment 1 shows that the same advertisements can either increase or decrease prices paid for selected brands, depending on the degree to which the choice situation requires brands to be recalled in order to be considered. However, an increase in prices paid caused by advertising does not necessarily imply detrimental effects on consumer welfare. Experiment 2 shows that, even under circumstances in which differentiating advertising leads consumers to select brands with higher average prices, it can provide useful information to consumers that allows them to make purchases that are more in line with their personal tastes than are the choices of consumers not exposed to the advertisements.
