Recent empirical work shows evidence for higher valuation of firms in countries with a better legal environment. We investigate whether differences in the quality of firm‐level corporate governance also help to explain firm performance in a cross‐section of companies within a single jurisdiction. Constructing a broad corporate governance rating (CGR) for German public firms, we document a positive relationship between governance practices and firm valuation. There is also evidence that expected stock returns are negatively correlated with firm‐level corporate governance, if dividend yields are used as proxies for the cost of capital. An investment strategy that bought high‐CGR firms and shorted low‐CGR firms earned abnormal returns of around 12% on an annual basis during the sample period. 相似文献

This article reviews the service management and marketing literature on managing people with a particular emphasis on managerial relevance. This review explores the market and financial results of managing people effectively, emphasizing that it is probably harder to duplicate high-performing human assets than any other corporate resource. The challenges inherent in boundary-spanning frontline jobs are discussed, including role conflict and emotional labor. Next, recommended human resources (HR) strategies and practices related to recruitment, training, empowerment, service delivery teams, and employee motivation are reviewed. The literature review concludes with a section on service culture, climate, and leadership. Each section is complemented with further research suggestions that emerged from interviews with eight academic and practitioner experts. The last section outlines six themes for new research opportunities with high potential managerial relevance; they relate to (1) the financial impact of HR practices and strategies, (2) motivating service employees, (3) training, (4) emotional labor, (5) dealing with rude customers, and (6) the impact of technology on managing service employees. 相似文献

We consider kernel density estimation for univariate distributions. The question of interest is as follows: given that the data analyst has some background knowledge on the modality of the data (for instance, ‘data of this type are usually bimodal’), what is the adequate bandwidth to choose? We answer this question by extending Silverman's idea of ‘normal‐reference’ to that of ‘reference to a Gaussian mixture’. The concept is illustrated in the light of real data examples. 相似文献

This paper introduces monopolistically competitive financial intermediaries into the New Keynesian DSGE setting. Modelling bank market power explicitly contributes to understanding two empirical facts: (i) The short-run transmission of changes in money market rates to bank retail rates is far from complete and heterogeneous. (ii) Stiffer competition among commercial banks implies that loan rates correlate more tightly with the policy rate. In my model, the degree of monopolistic competition in the banking sector has a sizeable impact on the pass-through of changes in the policy rate. In particular, a more competitive market for bank credit amplifies the efficiency of monetary policy. 相似文献

Every successful communication process requires a certain degree of self-disclosure. However, both in real life and on social network sites like Facebook, self-disclosure does not imply a total sacrifice of privacy. People rather tend to disclose one part of the self while keeping another one protected. In doing so, it is less important where the protective line is drawn, but that a line is drawn at all. This basic principle of conditional self-disclosure can be applied in diverse strategies. An online survey among German Facebook users (n = 684) examined this assumption. Items for a scale of subjective privacy regulation were derived from Burgoon’s four dimensions of privacy. Based on user’s varying emphasis on these privacy dimensions, seven different types of privacy management could be distinguished. Among these, six different strategies of conditional self-disclosure were observed (?chatty“, ?blogging“, ?networking“, ?sorting“, ?passive“, and ?inexperienced“). Only ?careless“ users did not follow our expectations, attaching none of the measured protective conditions to their self-disclosure. 相似文献
