Although International Quality Standards 9000 certification is one of the most popular quality assurance systems in the world, its contribution to a firm's value is still a controversial issue. This project re-examines this issue by using stock market reactions to the announcements of the award of certification made by a sample of Hong Kong listed companies, as a proxy for its contribution to a firm's value. The results suggest that on average certification increased a firm's value. However, most of this value increase was incorporated into stock prices before formal announcements were published in newspapers. In addition, the contribution of certification to value was greater in smaller firms than in larger ones. This can be attributed to fewer stock traders and professional analysts following smaller firms.  相似文献

This paper proposes the research framework that locus of control enhances entrepreneurship through the mediating mechanisms of increased social capital in interpersonal networks and improved human capital in personal development. We adopted structural equation modeling to examine the research hypothesis. The research participants comprised managers from 14 enterprises in China; a total of 1002 valid questionnaires were collected. The results revealed that social and human capital mediate the effect that internal locus of control exerts on entrepreneurship. This study provides the following research contributions: first, the findings address the gaps in previous studies regarding the effect that a single dimension (i.e. personality traits) produces on entrepreneurship. Second, by employing the social exchange and human capital theories, we integrated interpersonal and individual perspectives into the research framework to explore factors affecting entrepreneurship, identifying that social and human capital are key-mediating mechanisms through which locus of control influences entrepreneurship.  相似文献

This study suggests an integrative transfer of training model and examines the influence of pre-training performance on the relationship between work environment variables and transfer-related variables. Structural equation modeling was conducted with data collected from 365 Korean employees of a large general insurance firm. They were all participants in a leadership development program. The results of multi-group analyses revealed that the influence of work environment variables on transfer-related variables was moderated by employees' pre-training performance. The findings of the study imply that a more elaborate training transfer model that considers performance not just as an outcome variable, but also as an antecedent variable is required. Also, it is proposed that different strategies should be applied to promote transfer of training based on the employee's level of pre-training performance.  相似文献

We examine the proposition that firms with disproportionately more analysts herding in their coverage, as measured by a larger herding index value, have higher crash risk. Our findings are consistent with the main proposition. The results suggest that information production, rather than monitoring, is the primary mechanism behind the positive relation between herding and crash risk. Our conclusion is robust to different measures of crash risk, crash risk windows, herding measures, subsamples, and instrumental estimation. In addition, using post‐earnings announcement drift, we report that analyst herding slows down bad news transmission in the market. Our findings extend the literature by documenting that analyst herding plays a role in enhancing crash risk. Analyst herding has economic consequences on the covered firms. We offer support for the concern in the literature regarding analyst herding and market fluctuations.  相似文献

Based on a sample of 62 multinationals, this paper examines the impact of global diversification strategy on corporate profit performance by integrating the product and the international market dimensions of diversification. The results suggest that the corporate profit performance impact of related and unrelated diversification varies contingent upon the extent of a firm's international market diversification. One important lesson of this work is that both business strategy researchers and managers should review corporate diversification as having distinct yet interactive strategic dimensions—product and international market—and they would do well to recognize both the different and the joint effect of these dimensions on corporate profit performance.  相似文献

We exploit a unique setting of accounting regulation change to examine how accounting information quality affects the well-documented accrual anomaly. We show a significant reduction in the negative return predictability of accruals among UK companies with poorer accounting information quality following the introduction of Financial Reporting Standard No. 3: Reporting Financial Performance (FRS3). While the functional fixation hypothesis attributes the mispricing of accruals to the judgemental error of end-users of information, our findings suggest that the supply side of information also plays a crucial role. Our results provide evidence that regulatory interventions seeking to improve accounting information quality can reduce the mispricing of securities in the capital market.  相似文献

Using trade size from the Trade and Quote (TAQ) data set as a proxy for individual versus institutional trading, this paper finds that the effects of trading of these two types of investors on initial public offering (IPO) returns on the first trading day depend on the hotness of the IPO. My regression results reveal that IPOs’ open-to-close returns are positively related to small trade participation, small trade purchases, and small trade order imbalance in the hot IPO sample, but not in the cold and neutral IPO samples. In addition, the aftermarket prices of cold and neutral IPOs are primarily driven by the trading of institutional investors, who are less likely to be driven by sentiment.  相似文献

We investigate what stock return synchronicity reflects in terms of price informativeness by examining its effect on the pricing of seasoned equity offerings (SEOs). Based on 5,087 SEOs from 1984 to 2007, we find a significantly negative relation between stock return synchronicity (estimated as the logit transformation of the R-squared statistic from a two-factor regression) and SEO discounts (the percentage differences between pre-offer day closing prices and offer prices). The negative relation is strongest when there is no analyst coverage, and it declines as analyst coverage increases. This shows that stock price is more informative when stock return synchronicity is higher and also that information asymmetry can be mitigated by analyst coverage. We further decompose stock return synchronicity into the market comovement and industry comovement components and find that both components are equally important in affecting SEO discounts.  相似文献

土地整治功能分区及其整治方向研究   总被引:1,自引:0,他引:1  
[目的]土地整治的目标开始由注重"新增耕地"向注重"区域功能"转变,土地整治内涵由此得到延伸。同时,也迫切需要推进以提升区域功能为导向的土地整治分区研究。[方法]文章针对我国土地整治分区管理的需求,基于我国地理环境的背景差异及地域功能的定位、土地整治内涵的演变,运用要素加权叠加法、空间聚类分析法和专家经验判断法与区划对比分析法等开展土地整治功能分区。[结果]该文构建并提出了以功能导向为核心的土地整治分区体系和方案,将我国土地整治按地域功能划分为:(1)以生态修复、保护和建设为主的生态功能保育区,(2)以基本农田建设、农地开发整理、提高区域耕地的生产能力为主的粮食安全保障功能区,(3)以城乡用地统筹整治、城市用地内部挖掘为主的经济发展支持功能区,(4)以划定保护区、保护性建设为主的景观文化维护功能区等4种类型区,进一步结合东北平原区、华北平原区、黄土高原区等12个地理空间单元,组合为61个土地整治功能一级分区。在此基础上,评价一级功能区内各县域单元土地整治功能,识别出景观文化维护功能、粮食安全保障功能、生态建设功能、生态保护功能、城镇发展优化功能和城镇发展集聚功能,续分土地整治功能二级分区即各县域的土地整治功能。[结论]基于功能导向的土地整治分区反映了区域功能及其关系对土地整治分区的引导作用,为分区管控和引导提供了科学依据,这对提升区域功能和加强土地利用功能的联系和互动起到重要的作用。  相似文献

This paper examines the potential benefits of international investment in the Asia-Pacific capital markets. Using the viewpoints of U.S., Hong Kong and Japanese investors, the study shows that the returns from international investment within the region are more dependent upon the state of exchange rate changes. For the Hong Kong investors, despite the adopted pegged-rate between the Hong Kong dollar and U.S. dollar, the pattern of exchange returns from investing in the region resembles that of Japan rather than that of the U.S.  相似文献
