I demonstrate that providing information about product quality is not necessarily the best way to address asymmetric information problems when markets are imperfectly competitive. In a vertical differentiation model I show that a Minimum Quality Standard, which retains asymmetric information, generates more welfare than a label, which provides full information.  相似文献

Determinants of the stock price reaction to leveraged buyouts   总被引:1,自引:0,他引:1  
This paper investigates the determinants of leveraged buyout activity through the use of an abnormal return premium from the time of the first announcement through the final trading day. Consistent with the free. cash flow theory, firms with either high free cash flow or low Tobin’s q have higher abnormal returns. However, the returns to firms with both high free cash flow and low Tobin’s q are lower than firms with just one of these characteristics. Firms which substantially increase leverage and management buyouts with high insider ownership prior to the buyout have lower abnormal returns. Firms with lower risk, and therefore greater debt capacity, have higher abnormal returns.  相似文献

本文根据外资银行和国有商业银行向在中国境内的外资企业提供的外币贷款和人民币贷款的数据 ,对金融中介及关系银行进行了实证研究。我们的主要结论有两点 :第一 ,企业与银行建立起来的金融业务关系越长久 ,那么其所获得的外币贷款利率就越低。这是对金融中介理论的支持。另外 ,外资控股、第三方担保等因素 ,也具有降低外币贷款利率的效应。第二 ,人民币贷款的利率随着外资企业与更多的银行建立和保持合作关系而降低。人民币贷款主要是由我国商业银行提供。如果商业银行间的竞争仅仅是用来作为信贷定价的主要决定因素 ,而不是用来推进金融创新 ,提供高质量的金融产品和服务 ,那么这将会损害我国商业银行的获利能力并进而影响金融系统的健康发展。  相似文献

The stochastic approach to index numbers has been successfully applied to the estimation of inflation, the world interest rate and international competitiveness.?One distinct advantage of this approach is that it provides the whole distribution of the index, not simply one value. In this article, we extend the stochastic approach to the estimation of a stock market index. We demonstrate how this approach can be used to identify ‘redundant stocks’ that do not contribute significantly to the overall index.?For index tracking purposes, these stocks can be safely excluded.  相似文献

Changes in the exchange rate have direct and indirect effects on the prices of domestically produced goods and imports in the domestic market. The direct effects originate with the impact of the exchange rate on the marginal cost of imports; the indirect effects, with its impact on the price of materials used by domestic producers and hence on their marginal costs. Direct and indirect exchange rate pass-through elasticities are estimated for 37 Canadian manufacturing industries and their determinants are examined in a cross-section analysis. It is found that the direct and indirect elasticities are approximately equal in size for domestic goods, while the direct effect is dominant for imports. For a small number of industries, the net result of the direct and indirect effects is that a depreciation of the domestic currency increases the competitiveness of imports, contrary to conventional analysis. Important determinants of the direct (indirect) elasticities are the import share and non-tariff barriers (the responsiveness of domestic costs to changes in the exchange rate, and concentration).  相似文献

Recent developments in environmental and animal welfare issues, and the introduction of new production practices may have affected consumer attitudes and preferences toward differentiated product choice. Factors such as animal well-being, environmentally friendly production, and the use of antibiotics appear to be increasingly core consumer concerns. We link the aforementioned with Maslow's hierarchy of needs suggesting that the higher income consumers should be more altruistic in their consumptive behavior and test this by evaluating consumer preferences for these attributes in pork chops. We also test whether social consciousness of the consumers translates into choice behavior. Data was obtained by choice experiment surveys and mixed logit estimation was used to estimate consumers' willingness-to-pay for the credence attributes. Results reveal that both, higher income and socially aware consumers are on average willing to pay higher premiums for the antibiotic-free attribute, but not for other two social attributes. Also, the group of higher income consumers is highly heterogeneous in their preferences, whereas socially aware consumers tend to be more homogeneous in their preferences.  相似文献

This is the first paper to consider a mixed oligopoly in which a public Stackelberg leader competes with both domestic and foreign private firms. The welfare maximising leader is shown to always produce less than under previous Cournot conjectures. Introducing leadership also alters previous public pricing rules resulting in prices that may be either greater than or less than marginal cost depending on the relative number of domestic firms. Furthermore, entry of a foreign firm will increase welfare only when the relative number of domestic firms is small, but that share is shown to be larger than has been indicated without leadership. Unlike previous models, the influence on public profit of a foreign acquisition is ambiguous and is related to the relative number of domestic firms. Finally, the consequences of privatisation are shown, for the first time, to depend on the relative number of domestic firms.  相似文献
