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  相似文献

审计市场中的合并、产业专用化投资和价格竞争   总被引:1,自引:0,他引:1  
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。  相似文献

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.  相似文献

In this essay we review the evidence from marketing research about price presentation of consumer products and discuss how these lessons have been applied—consciously or unconsciously—in the design of the U.S. tax system. Our perspective is that, in most situations, the designers of the tax system attempt to minimize the perceived burden of any given amount of tax collections. We allow, though, that in certain situations an additional goal is to maximize the perceived burden of others. We also investigate how, when the objective is to encourage a particular activity, price presentation may enhance the achievement of that goal for a given amount of tax subsidy. We conclude by addressing the ethical and normative implications of price presentation in the tax system.  相似文献

This paper investigates the benefits of allowing households to compensate the portfolio distortion due to their housing consumption through investments in housing price derivatives. Focusing on the London market, we show that a major loss from over-investment in housing is that households are forced to hold a very risky portfolio. However, the strong performance of the London housing market means that little is lost in terms of expected returns. Even households with limited wealth are better off owning their home rather than renting and investing in financial assets, as long as they are willing to face the financial risk involved. In this context, access to housing price derivatives would benefit most poor homeowners looking to limit their risk exposure. It would also benefit wealthier investors looking for the high returns provided by housing investments without the costs of direct ownership of properties. Comparisons with French, Swedish and U.S. data provide a broader perspective on our findings.  相似文献

Abstract. We reexamine and extend tests of the uncertain information hypothesis (UIH) proposed by Brown, Harlow, and Tinic (1988, 1993). We find that their empirical results are sensitive to the sampling procedure employed and that their particular methodology does not sufficiently distinguish between event and nonevent periods. When the sampling procedure is modified to identify only relatively large, isolated events, the test results generally do not support the UIH. Instead, significant price shocks are consistently followed by short-lived price reversals. We observe this behavior following positive and negative events regardless of whether the event is classified as risk increasing or risk decreasing.  相似文献

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.  相似文献
