In hiring decisions, universities explicitly reward focusing on a specific field. I model the use of research specialization (focusing) in hiring as a signal of ability. Without explicit reward for focusing, candidates who focus are more likely to be able. However, if job market rewards focusing, less able candidates who would otherwise be indifferent between focusing or not, start focusing, which leads to smaller likelihood of observing an able candidate among those who focus than among those who do not. Specialization works as an effective ability signal only when generation of good ideas is highly likely for all ability levels. 相似文献

Does network board capital matter? A study of innovative performance in strategic SME networks 总被引:1,自引:0,他引:1
This article examines the effects of network board capital (i.e., human capital and relational capital) on total, radical and incremental network innovative performance. Results from a five-year longitudinal study of network boards in 53 strategic networks suggest that a network board's diversity, education level, and interlocking directorates with other such networks affect network innovative performance. The degree of board diversity and interlocking directorates primarily influence incremental innovation, whereas education level influences radical innovation. The study finds that a network board's diversity of expertise and education level are important for improving all components of innovative performance (total, radical and incremental) in smaller networks. Managerial implications of these findings are discussed. 相似文献

We examine whether institutional investors are able to avoid future litigation. Our results show that institutions provide a fiduciary role by decreasing or eliminating their positions in sued firms well before litigation begins. We also find that institutional groups with high monitoring ability (independent investment advisors and mutual funds) are more proactive in their trading behavior than are institutions with low monitoring ability (banks, insurance companies, and unclassified institutions such as endowments, foundations, and self-managed pension funds). We find that percentage changes in institutional ownership are correlated with public information available more than two quarters before litigation. 相似文献

This article suggests a new approach to approximating moments for nonlinear DSGE models. This approach is fast and sufficiently accurate to estimate nonlinear DSGE models. A small financial DSGE model is repeatedly estimated by several modifications of the suggested approach. Approximations of the moments are close to the results of the large sample Monte Carlo estimation. The quality of parameter estimation using our suggested approach is close to the Central Difference Kalman Filter (CDKF); and our suggested approach is much faster. 相似文献

The time-shift asymmetric correlation analysis method is introduced for stock exchanges with different but non-overlapping trading hours to analyze the degree of global integration between stock markets of different countries and their influence on each other. Next-day correlation (NDC) and same-day correlation (SDC) coefficients are introduced. Correlations between major U.S. and Asia-Pacific stock market indices are analyzed. Most NDCs are statistically significant while most SDCs are insignificant. NDCs grow over time and the U.S. stock market plays a pacemaking role for the Asia-Pacific region. The correlation coefficients can be used as a measure of the degree of globalization for the corresponding countries. 相似文献

This study centers on the transformation of management and the consumer in the Soviet Union, Czechoslovakia, Hungary, and Poland. Carried out in collaboration with scholars in these countries, the study outlines the impact of the transformation to a market economy on managers and consumers, and discusses the adjustments which managers and consumers have been making in response to new economic realities. © 1992 John Wiley & Sons, Inc. 相似文献

This article examines the cross-sectional and time-series determinants of commercial mortgage credit spreads as well as the terms of the mortgages. Consistent with theory, our empirical evidence indicates that mortgages on property types that tend to be riskier and have greater investment flexibility exhibit higher spreads. The relationship between the loan-to-value (LTV) ratio and spreads is relatively weak, which is probably due to the endogeneity of the LTV choice. However, the average LTV ratio per lender has a strong positive relation with credit spreads, which is consistent with the idea that lenders specialize in mortgages with either high or low levels of risk, and that high LTV mortgages require substantially higher spreads. Finally, we observe that spreads widen and mortgage terms become stricter after periods of poor performance of the real estate markets and after periods of greater default rates of outstanding real estate loans. 相似文献

This article examines financial time series volatility forecasting performance. Different from other studies which either focus on combining individual realized measures or combining forecasting models, we consider both. Specifically, we construct nine important individual realized measures and consider combinations including the mean, the median and the geometric means as well as an optimal combination. We also apply a simple AR(1) model, an SV model with contemporaneous dependence, an HAR model and three linear combinations of these models. Using the robust forecasting evaluation measures including RMSE and QLIKE, our empirical evidence from both equity market indices and exchange rates suggests that combinations of both volatility measures and forecasting models improve the forecast performance significantly. 相似文献
