从博弈的角度看中小股东解决纠纷的过程--从一个流行模型的残缺谈起

经研究发现 ,张维迎教授在 2 0 0 1年第五版的《博弈论与信息经济学》中所借用的承诺要胁诉讼博弈例子中对诉讼费用的处理有点不妥 ,便作出了适当的调整 ,但却得出了令人沮丧的结论 :承诺要胁诉讼不成立 !继续研究发现只有打破这种败诉风险由当事人承担的机制 ,才能传递出有力量的信号 ,才能做到真正的威胁 ,那就是建立“生死与共”的竞争性的律师定价机制和保费率真正是胜诉率信号的诉讼费用保险机制与最经济的诉讼程序与非诉讼程序、保障其实现的机制和可供的备选机制。本文论证了其合理性

审计市场中的合并、产业专用化投资和价格竞争

本文从产业组织的角度，分析了审计市场的合并、产业专用化和价格竞争等竞争行为，并进一步探讨了这些行为对审计质量和社会福利的影响。本文认为，审计质量的信号传递机制推动了产业中的合并行为，而审计产业的专用化投资行为在于策略性地阻止进入。由于审计产品的异质性、信任品特性以及强大的买方谈判能力使得审计市场存在激烈的价格竞争，而合并和产业专用化投资有助于事务所降低成本。因而，审计市场的竞争提高了社会福利。     

基于供应链管理的房地产开发企业合伙模式研究

基于供应链的思想，传统制造业中的各个企业被看作整个供应链中的某一环节，供应链管理使企业集中优势资源与精力创造特殊价值，提高自身竞争能力并带动相关企业发展。房地产开发企业作为自身行业中的“集成制造商”，应该充分借鉴供应链管理的思想，大力发展与相关合作对象的伙伴关系，基于其独特的供应链的内部集成，建立合适的合伙模式，以达到降低开发成本、提高项目品质、增强企业核心竞争力的目标。     

The survivorship bias, share price effect, and small firm effect in Canadian markets

After controlling for survivorship bias, we examine the relation between average returns, firm size, and price levels for Canadian stocks during the 1975-1994 period. Our findings indicate that there is a significant inverse share price level effect in Canadian markets. When we compare the results of the overall sample with the groups of surviving firms and delisted stocks, the latter group shows strong performance for large-size, high-priced stocks. Evidence that supports an independent size effect is less clear for Canadian stocks. A small size effect exists only among the higher share price denominations, which suggests a confounded size-price effect. Although the delisted group returns are statistically different from those of the survivor and the overall groups, which implies some evidence of survivorship bias, the difference between the survivor group and the overall group is weak at best.     

Three New Real Estate Price Indices for Geneva,Switzerland

This paper develops constant-quality price indices for three categories of real estate-apartment buildings, vacant land, and condominiums—for the city of Geneva, Switzerland. We use both the hedonic and repeat sales models to estimate the price level and, in turn, the rate of price change. The general pattern of each series suggests that real estate prices in Geneva were fairly stable throughout the 1970s, increased sharply during the 1980s, but gave back some of these gains in the early 1990s. Interestingly, the sharp rise in prices in the second half of the 1980s is very similar to that found in some regions of the United States. We also consider the problem, implicit in the repeat sales method, of revisions in previously estimated price indices as additional data become available in later years.     

Subordinated Market Index Models: A Comparison

The paper compares various processes subordinated to the Wiener process tomodel the leptokurtic characteristics of index returns. Empirical analysisis performed on the Dow Jones and Nikkei 225 indexes. A good model to capturethe typical tail behaviour of these indexes turns out to be a long Studentt distributed one.     

股票价格均值回归理论研究综述

随机漫步理论认为股票的价格是不能预测的,许多实证检验的结果也支持了这一结论。但是,近年来均值回归理论对随机漫步理论提出了挑战。从长期来看,股票价格呈均值回归是必然的;均值回归具有不对称性;政府行为对股票的均值回归具有一定的影响。     

金融期货价格波动限制机制探讨

金融期货价格稳定机制延缓了价格发现过程，并造成了流动性干扰，但从降低期货、现货交易总成本来讲，它还是利大于弊，因此设置价格波动限制是一种可行的政策，而且在期货、现货市场同时设定的效果最好。此外，从不同价格波动限制方式的影响来看，选择弹性涨跌幅限制可较好地发挥价格限制的好处，减小价格限制的不利影响。     

The Friday Effect in European Securitized Real Estate Index Returns

This study extends research on the day-of-the-week effect towards European real estate indices. We examine this anomaly for several European securitized real estate index returns between 1990 and 2003. Although the countries under analysis have unique country-specific patterns, we find that eight out of eleven European countries exhibit abnormally high Friday returns. Moreover, two different Europe indices also exhibit the Friday anomaly. The anomaly is robust with respect to extreme observations, alternative specifications and several well-known calendar effects.
