A convexity property of the two-by-two model of production

It is shown that the rental of the ith primary factor in terms of the jth product is a convex function of the relative price of the jth commodity if and only if the weighted elasticity of factor substitution is greater in whichever industry employs the ith factor relatively intensively the weights being the shares of the ith factor in the total costs of the two industries.     

次贷危机中的中国:看到危险,更要看到机会

美国次贷危机正在演变成全球经济危机,这是全球经济结构失衡以及金融监管不能适应金融模式创新导致的一次真正的全球化时代的金融危机.其对中国而言,既是危机,也是机遇.全球经济危机无疑会对中国经济产生强烈的冲击,但在全球化时代,中国已经积累相当的经济实力,只要宏观政策应对得当,就可以将危机转化为中国崛起的机遇.     

金融机构的政府救助与监管声誉:一个理论框架和现实解释

在金融市场上,政府监管的声誉反映了对金融机构的威慑力,针对金融机构的违规破产,政府不合理的救助行为会极大损害其监管声誉,降低威慑力,同时金融机构道德风险的产生和违规概率加大会造成政府救助成本的进一步增加和社会总财富的持续减少。本文通过简化的KM RW模型分析了这一过程,并认为这一现象实质上反映了中国金融市场秩序和法律秩序深层次的矛盾冲突,应当积极建立承诺可信的规范的监管秩序。     

Total Factor Productivity Growth in U.S. Commercial Banking for 1935–1991: A Latent Variable Approach Using the Kalman Filter

This paper studies total factor productivity (TFP) in U.S. commercial banking for 1935–1991. TFP can contain a procyclical bias when some input factors are not freely variable, causing their shadow and market prices to differ. We correct this bias in TFP by decomposing it into its latent stochastic trend and cyclical components by employing the Kalman filter. Using the FDIC's annual aggregate data on U.S. insured commercial banks, we report that the stochastic trend has been positive during 1935–1991, with an average annual growth rate of 2.27%, and that it exhibits a decaying time path. We attribute the positive TFP growth to technical change.     

Moderating effects of the fit between service tangibilization and organizational performance

As the significance of service industry grows, its relationship to overall economic growth and organizational performance (OP) has also become an issue of prominence. Tangibilization is widely known as one of the means of overcoming the weaknesses of service intangibility and improving OP. This research explores the relationship between service tangibilization and OP. Furthermore, the moderating effect of the fit between service tangibilization and OP will also be discussed in the business context. Specifically, the Korean natural gas industry is selected to test the developed hypotheses. The managers who have experience with managing a service business in either the wholesale or retail sector of this industry were surveyed. The results imply that there exists a significant relationship between service tangibilization and OP, with the mental fit positively strengthening some of the relationships between these two constructs. It can be inferred from this that it is important for companies in the natural gas industry to attain the right fit of mental tangibilization in order to effectively deploy service tangibilization and maximize their OP.     

Tiger Woods,Nike, and I are (not) best friends: how brand's sports sponsorship in social-media impacts brand consumer's congruity and relationship quality

This study examines the effects of brand's sports sponsorship in social media on brand consumer's congruity and brand relationship quality. The study included a survey of targeting consumers whose ages range between early twenties and late forties; data from 322 respondents were collected. The results are as follows. First, brand's sports sponsorship in social-media activities relating to sports brands has significant effects on brand consumer's congruity. Second, this congruity significantly influences brand relationship quality. Third, male consumers, who have previously purchased products and services associated with a sports brand, perceive the sponsor's brand image more positively when they are exposed to the sponsor's brand's sports sponsorship in social-media activities, compared to those consumers having no previous purchases of the sponsored brand. Lastly, consumers in their forties with prior experience consuming the sponsor's brand products are most affected by the level of self-congruity with the sports brand compared to younger or older consumers.
