金融理论界对规模溢价与价值溢价现象的困惑与争论由来已久,对上述现象的理论解释可以归纳为传统范式与行为范式。前者认为,溢价是对高风险的补偿,后者则认为,溢价源是对过度反应的纠正。为了弄清溢价形成的真正原因,本文对1993——2003年中国深沪A股进行了实证分析,研究发现:中国A股市场存在规模与价值溢价现象,但上述两种范式的解释均存在一定的局限性。本文借鉴展望理论的参照依赖原理,提出相对盈利的概念,并对溢价现象予以新的解释。 相似文献

Credit derivatives pricing models before Basel III ignored losses in market value stemming from higher probability of counterparty default. We propose a general credit derivatives pricing model to evaluate a Credit Default Swap (CDS) with counterparty risk, including the Credit Valuation Adjustment (CVA) in order to optimize the economic capital allocation. We work from the model proposed by Luciano (2003, Working Paper, International Center of Economic Research) and the general pricing representation established by Sorensen and Bollier (Financial Analysts Journal 1994;50(3):23–33) to provide a model close to the market practice, easy to implement and fitting with Basel III framework. We approach the dependence between counterparty risk and that of the reference entity with a technical tool: the copula, in particular, the mixture one that combines common “extreme” copulas. We study the CDS's vulnerability in extreme dependence cases. By varying Spearman's rho, the mixture copula covers a broad spectrum of dependence and ensures closed form prices. We end up with an application on real market data. 相似文献

This paper clarifies the factors influencing customers' perceptions of premium service and superiority for high-value-added domestic airline services in Japan, and explains how these perceptions impact customer loyalty.To gather data for the analysis of consumers' perceptions, a questionnaire survey of 515 respondents who use high-value-added domestic airline services was conducted. These respondents' data were analyzed using structural equation modeling.The most valuable finding is the distinction between the perceptions of premium service and superiority, both of which strongly influence customer loyalty. This finding has two important implications. First, staff correspondence has a strong influence on customer loyalty – not directly, but through customers' perceptions of premium service and superiority. Second, perceptions of premium service and superiority influence customer loyalty separately. This finding may assist in the development of innovative high-value-added services. 相似文献

Worldwide premium private labels (PPLs) are a new and rapidly growing phenomenon. However to date, little is known about consumers' perceptions of these newer entrants relative to other brand types. Therefore it is difficult for marketers to understand the opportunities and threats created by this new generation of brands. This study examines the ways in which consumers categorise PPLs compared to more traditional value private labels (VPLs) and national brands (NBs) on the three dimensions of quality, value for money and trust. The data includes seven packaged goods categories in three countries, the United States, the United Kingdom, and Australia. The findings show that PPLs sit on a separate island, in between VPLs and NBs in consumer memory. While consumers generally view PPLs as a separate subgroup of brands, PPL are connected to other subgroups in that they are perceived to have the value characteristics of VPLs but quality characteristics of NBs. Finally, consumers with past experience with VPLs have a stronger ability to categorise PLs into distinct brand tiers. 相似文献

In premium auctions, the highest losing bidder receives a reward from the seller. This paper studies the private value English premium auction (EPA) for different risk attitudes of bidders. We explicitly derive the symmetric equilibrium for bidders with CARA utilities and conduct an experimental study to test the theoretical predictions. In our experiment, subjects are sorted into risk-averse and risk-loving groups. We find that revenues in the EPA are significantly higher when bidders are risk loving rather than risk averse. These results are partly consistent with theory and confirm the general view that bidders' risk preferences constitute an important factor that affects bidding behavior and consequently also the seller's expected revenue. However, individual subjects rarely follow the equilibrium strategy and revenue in our experiment is lower than in the symmetric equilibrium. 相似文献

This article reviews the empirical evidence for equity returns, bond returns, and the equity premium in the German capital market for the period from 1870 to 1995. Taken together, the studies reviewed provide convincing evidence that over longer investment periods, average equity returns have been higher than average bond returns. These excess returns, however, have been highly volatile and negative in many years, illustrating the higher risk of equity investments. Moreover, market timing had a major positive or negative impact on overall returns. Despite the historical evidence of a substantial equity premium there is still little equity investment by German households. 相似文献

近年来,我国并购市场如火如荼,越来越多的企业选择通过并购来实现自己的战略目标,迅速占据市场地位,进入新兴行业。在并购交易热潮下,高溢价似乎也成为并购重组的"标配",高溢价并购屡见不鲜。可是企业支付高溢价换来的是否为优质资产,其是否能给企业带来价值的提升,这些都是值得研究的议题。因此,文章基于我国并购交易市场,研究了国内上市公司并购溢价的绩效反应。运用相关性分析、多元回归分析等研究方法探讨了并购支付溢价对并购绩效的影响。最后,根据实证研究结果阐述本文的结论,给出相应的建议。研究结果表明:并购溢价在一定程度上代表了并购后协同效应的大小,支付的溢价越高表明预期达成的协同效应越大,企业后期的绩效表现会越好。 相似文献

试析我国金融资产收益变动对寿险保费的影响 总被引:1,自引:0,他引:1
在金融资产选择理论框架下,利用时间序列研究了金融资产长期、短期波动对寿险保费的主要影响。并从居民投资角度建立了寿险与部分金融资产间的ECM模型,结果发现:储蓄增长对保费短期贡献大于长期贡献,加息会在短期内刺激保费增加但长期内有抑制作用;国债和股票受结构性因素影响未表现出与寿险保费有长期均衡关系。寿险公司在短期内应把部分储蓄转化为保费;在长期内应拓展新营销渠道,加快寿险产品和保障型产品的开发。 相似文献

Accurate estimation of the equity premium (the expected difference between the returns to a well-diversified stock market portfolio and a riskfree asset) is of central importance in many applications of finance theory including project appraisal and portfolio selection. The standard approach is to take the average observed excess returns to the market over some recent time period (sometimes referred to as the ex post equity premium) and apply this as an unbiased estimate of the ex ante equity premium. The paper reviews the problems associated with such an approach and contrasts it with alternative theoretical techniques. 相似文献

Fam和French(1993)提出的三因子模型,已经被国外很多学者证明能较好的解释股票的收益率差异.本文正是在其理论基础上,采用了类似的验证方法来检验中国的股票市场是否能用三因子模型解释,结果发现在大部分行业,它也同样能适用于中国的股票市场. 相似文献
