Using a sample of Chinese mutual funds, we empirically assess how managerial heterogeneity affects mutual fund performance. We find that funds with higher manager fixed effects outperform those with lower manager fixed effects by 2% per year. We also note that fund performance improves after managers with higher fixed effects are hired. The results are consistent with the notion that manager fixed effects are associated with managerial innate ability. Finally, we find that investors pay attention to managerial attributes beyond the traditional performance measures, providing supporting evidence for the rational explanation of convex flow‐performance sensitivity in the literature. 相似文献

This paper discusses the role of clusters and subcontracting as factors in the evolution of small and medium firms in Indonesia during the last quarter century. It is argued that a number of such firms have become successful exporters of rattan furniture, wood furniture and garments on the strength of subcontracting relationships with foreign investors and buyers as well as agglomeration economies achieved by clustering in selected locations. Examples are provided to show that clustered enterprises are more likely to be in the exports business and to adopt product and process innovations as compared to more dispersed firms. Public policy support for fostering subcontracting links and cluster formation is also discussed. 相似文献

In this paper, we propose a new model of adoption and repurchase due to upgrades driven by the utility of technology products that keep improving. The model is able to predict product life cycle patterns that could not be explained previously. Such patterns were used to challenge diffusion theory validity. Mathematically, the model is described as a nonlinear discrete system that depends on a small set of parameters. We investigate the dynamic properties of the nonlinear system using numerical stability analysis. We find domains in the parameters space in which the equilibrium point and the periodical orbits are stable. The domains correspond to population heterogeneity, tendency to upgrade, and the influence of industry response on market dynamics. We also implement our model to fit actual data of two real-world product life cycles with many irregularities and benchmark the results of our model vs. well-known models. 相似文献

In the microstructure literature, information asymmetry is an important determinant of market liquidity. The classic setting is that uninformed dedicated liquidity suppliers charge price concessions when incoming market orders are likely to be informationally motivated. In limit order book (LOB) markets, however, this relationship is less clear, as market participants can switch roles, and freely choose to immediately demand or patiently supply liquidity by submitting either market or limit orders. We study the importance of information asymmetry in LOBs based on a recent sample of 30 German Deutscher Aktienindex (DAX) stocks. We find that Hasbrouck's (1991) measure of trade informativeness Granger causes book liquidity, in particular that required to fill large market orders. Picking-off risk due to public news-induced volatility is more important for top-of-the book liquidity supply. In our multivariate analysis, we control for volatility, trading volume, trading intensity and order imbalance to isolate the effect of trade informativeness on book liquidity. 相似文献
