This study examines companies with two classes of shares that entitle their holders to identical cash flow and voting rights but that are available to mutually exclusive sets of investors: A shares to domestic investors and B shares to foreign investors. Price differences between A and B shares are higher in firms with a greater disparity in the disclosures that they make to domestic and foreign investors. This association is more pronounced when the cost (benefit) of information transfer is higher (lower). The results suggest that disclosure disparity creates meaningful differences in investors' average information precision across A and B shares and thus influences the cross-sectional variation in price differences.  相似文献

The subject of design and technology was introduced to the curriculum for high schools in China 10 years ago. However, the teaching and learning of this subject have become difficult for both teachers and students because there is a lack of qualified teachers with design background to deliver this subject in a way to stimulate the learning interests of the students. This paper presents a research that is aimed at improving this situation by integrating the teaching and learning of design and technology within a computational environment as part of social networks sites. The purpose is to enable the collaboration among the students and interaction between teachers and students. In this research, a series of investigations were conducted, by following through several taught subjects in design and technology in prominent high schools in China. Based on these investigations, a theoretical framework for web-based design learning and teaching system in the style of social networking is developed, implemented and tested, emphasizing three features of design: innovation, collaboration, and interaction. This framework has been tested among high school students and teachers in a high school in Nanjing. It identified and validated necessary techniques and design features required to make an education-related social networking site effective and affective for the students and teachers. The results of this research indicated that social networking sites have significantly positive values in design education, especially for the collaboration and interaction on the subject of design and technology.  相似文献

This paper investigates the effect of including the customer loan approval process to the estimation of loan performance and explores the influence of sample selection bias in predicting the probability of default. The bootstrap variable reduction technique is applied to reduce the variable dimension for a large data-set drawn from a major UK retail bank. The results show a statistically significant correlation between the loan approval and performance processes. We further demonstrate an economically significant improvement in forecasting performance when taking into account sample selection bias. We conclude that financial institutions can obtain benefits by correcting for sample selection bias in their credit scoring models.  相似文献

While the beneficial impacts of supplier and customer integration are generally acknowledged, very few empirical research studies have examined how an organization can achieve better product performance through product innovation enhanced by such integration. This paper thus examines the impact of key supplier and customer integration processes (i.e., information sharing and product codevelopment with supplier and customer, respectively) on product innovation as well as their impact on product performance. It contributes to existing literature by asking how such integration activities affect product innovation and performance in both direct and indirect ways. After surveying 251 manufacturers in Hong Kong, this study tested the relationships among information sharing, product codevelopment, product innovativeness, and performance with three control variables (i.e., company size, type of industry, and market certainty). Structural equation modeling with correlation and t‐tests was used to test the hypothesized research model. The findings indicate a direct, positive relationship between supplier and customer integration and product performance. In particular, this study verifies that sharing information with suppliers and product codevelopment with customers directly improves product performance. In addition, this study empirically examines the indirect effects of supplier and customer integration processes on product performance, mediated by innovation. This has seldom been attempted in previous research. The empirical findings show that product codevelopment with suppliers improves performance, mediated by innovation. However, the sampled firms cannot improve their product innovation by sharing information with their current customers and suppliers as well as codeveloping new products with the customers. If the adoption of supplier and customer integration is not cost free, the findings of this study may suggest firms work on particular supplier and customer integration processes (i.e., product codevelopment with suppliers) to improve their product innovation. The study also suggests that companies codevelop new products only with new customers and lead users instead of current ones for product innovation. For managers, this study has demonstrated that both information sharing and product codevelopment affect performance directly and indirectly. Managers should put more emphasis on these key processes, especially when linked with product innovation. Managers should consider involving their suppliers and customers in the early stages of design. Information sharing with suppliers is also important in product development. As suggested by this study, extensive effort on supplier and customer integration should be made to directly augment current product performance and product innovation at the same time.  相似文献

国际组织在一定程度上是全球治理中的自主行为体,它能自主确定全球问题的应对之道。在国际组织的行政与管理机构中,来自组织等级制度的行政权威与来自专门知识的专业权威构成了一对矛盾关系。根据占据主导地位的权威类型,国际组织的行政模式可以被划分为行政权威主导与专业权威主导两种模式。这两种模式在部门决策自主性、对正式程序的依赖度、招募人员的偏好以及与外部环境的关系处理上存在很大差异。利用这一分析框架,作者以世界卫生组织中全球艾滋病计划从建立到被裁撤的过程为例,具体探讨了行政模式如何影响国际组织对治理路径的选择。在专业权威主导的行政模式下,世界卫生组织将尊重人权作为应对艾滋病问题的核心,制定并推行了一套强调对成员国内部政治社会事务进行干预的治理方案。随着行政权威占据主导,世界卫生组织没有维持先前的治理路径,退回到了单纯依赖医学手段的技术性治理路径上。  相似文献
