The effects of network groups on minority employee turnover intentions

Companies in the United States are concerned with retaining minority employees to maintain or increase the diversity of their workforce. Here we assess the value of one approach companies have used to retain minority employees: “network” groups. Based on data obtained from a large company with extensive network groups, this study compares the turnover intentions of minority employees who have joined one of the company's network groups to those who have not joined one of the company's network groups. The data show that employee network groups can be useful in helping companies retain managerial‐level minority employees. Extensive recommendations are provided to help organizations maximize the effectiveness of network groups. © 2002 Wiley Periodicals, Inc.

Stock market volatility,the news,and monetary policy

The dynamic relationship linking the volatility of equity prices with “the news” and the expected path for monetary policy is investigated. Previous results that link the impact of the news about real activity to changes in current and future interest rates are employed in developing a positive link between changes in volatility and the news. Empirically, our results uncover a positive and statistically significant response of the CBOE volatility index, VIX, to unanticipated changes in employment, but not to inflation. Hence, agents' expectations for the policy response to news have an important influence on the expected volatility of stock prices. (JEL E44, E52)     

解读会计信息产权

会计信息外部性的存在带来会计信息供求的冲突,解决此冲突的规则就是会计信息产权。会计信息产权需要界定才能发挥其应有的效能,会计信息产权的界定取决于对企业所有权分享、管制和道德等因素,企业所有权分享下的会计信息产权界定是初始的界定,无法完成初始界定时可采用管制方式进行强权界定,道德是会计信息产权界定不可缺少的因素。国企改革所滋生的各种问题的根源在于会计信息产权畸形性,欲抑制其畸形,正确处理国企所有权的分享问题的同时,建立“共同治理”的机制和“相机治理”机制是必不可少的。     

A generalized theorem of the maximum

Summary This paper generalizes the Theorem of the Maximum (Berge [2]) to allow for discontinuous changes in the domain and the objective function. It also provides a geometrical version of the (generalized) theorem.This research was supported in part by National Science Foundation Grant SES-86-19012.
