This study develops a model in which transformational leadership affects team coordination and performance through the conflict management approaches adopted by team members. Data were collected from three different sources in a lagged design from 108 teams in a large enterprise in China. Results support the reasoning that transformational leadership promotes team coordination and thereby team performance by encouraging teams to adopt a cooperative, as opposed to competitive, approach to conflict management. These results suggest that transformational leadership may help team members manage conflicts for their mutual benefit. This is an important mechanism through which transformational leadership enhances team coordination and, in turn, achieves higher team performance.  相似文献

In generalized autoregressive conditional heteroskedastic (GARCH) models, the standard identifiability assumption that the variance of the iid process is equal to 1 can be replaced by an alternative moment assumption. We show that, for estimating the original specification based on the standard identifiability assumption, efficiency gains can be expected from using a quasi-maximum likelihood (QML) estimator based on a non Gaussian density and a reparameterization based on an alternative identifiability assumption. A test allowing to determine whether a reparameterization is needed, that is, whether the more efficient QMLE is obtained with a non Gaussian density, is proposed.  相似文献

How Sensitive Is Investment to Cash Flow When Financing Is Frictionless?   总被引:18,自引:1,他引:17  
I analyze the sensitivity of a firm's investment to its own cash flow in the benchmark case where financing is frictionless. This sensitivity has been proposed as a measure of financing constraints in earlier studies. I find that the investment–cash flow sensitivities that obtain in the frictionless benchmark are very similar, both in magnitude and in patterns they exhibit, to those observed in the data. In particular, the sensitivity is higher for firms with high growth rates and low dividend payout ratios. Tobin's q is shown to be a more noisy measure of near-term investment plans for these firms.  相似文献

Die Bedeutung des Humankapitals für das künftige Wirtschaftswachstum ist allgemein anerkannt. Gleichzeitig sto?en steigende Studienanf?ngerzahlen auf knappe Bildungsbudgets in den Bundesl?ndern. Wie wird sich die Zahl der Studienanf?nger bis 2020 entwickeln? Wird es eine entsprechende Nachfrage nach Hochschulabsolventen geben? Welcher Kapazit?tsaufbau ist an den Hochschulen erforderlich und was wird er kosten?  相似文献

One of the rapidly growing areas in industrial marketing is the application of sales force automation (SFA) technologies to help improve the efficiency of the sales force task. What is often overlooked is that there are some potential negative effects related to SFA technologies that arise when these innovations are forcefully adopted on the individual salesperson. This study empirically examines the psychological and social antecedents of salespeople's resistance toward SFA technologies in South Korea. Unlike previous studies that only looked at adoption, this studies adds to the literature on SFA technologies by looking at resistance toward innovation in the post-adoption or intra-organizational diffusion stage. This study looks at the direct and indirect relationships between innovation resistance and some key constructs such as job satisfaction, job performance, self-efficacy, group-efficacy, innovativeness, and peer usage. This study represents also one of the very few empirical studies conducted on sales force behavior in South Korea and as such may offer some insights on sales force management in collectivist cultures.  相似文献

In the 1980s it became increasingly clear that the European Community market was still segmented by national borders because of non-tariff barriers to trade. A major objective of the Single Market Program in 1992 was to remove these barriers, thereby enforcing intra-union competition. In this paper, a panel of Swedish firm-level data is used to evaluate whether domestic market power has been curtailed as a consequence of the SMP and of the Swedish membership in the European Union in 1995. Evidence of increased competition emerges, as price-cost margins have declined in industries with high non-tariff barriers prior to 1992. JEL Classification Numbers: F15, L11, C33  相似文献

In this study, we consider Bayesian methods for the estimation of a sample selection model with spatially correlated disturbance terms. We design a set of Markov chain Monte Carlo algorithms based on the method of data augmentation. The natural parameterization for the covariance structure of our model involves an unidentified parameter that complicates posterior analysis. The unidentified parameter – the variance of the disturbance term in the selection equation – is handled in different ways in these algorithms to achieve identification for other parameters. The Bayesian estimator based on these algorithms can account for the selection bias and the full covariance structure implied by the spatial correlation. We illustrate the implementation of these algorithms through a simulation study and an empirical application.  相似文献
