Conditioning manager alphas on economic information: another look at the persistence of performance 总被引:11,自引:0,他引:11
This article presents evidence on persistence in the relativeinvestment performance of large, institutional equity managers.Similar to existing evidence for mutual funds, we find persistentperformance concentrated in the managers with poor prior-periodperformance measures. A conditional approach, using time-varyingmeasures of risk and abnormal performance, is better able todetect this persistence and to predict the future performanceof the funds than are traditional methods. 相似文献

The six largest U.S. airlines announced in the beginning of 1998 the formation of three domestic alliances, but the size and scope of these alliances spurred significant public interest concerns. GAO analysis suggests a rough equivalence between the domestic costs and benefits of alliances, yet the international competitive effects have not been considered. I argue that the national welfare merits of domestic airline alliances turn on positive international competitive effects. Empirical tests - run on comprehensive panel data covering the international airline markets among 21 nations over the 1983–1992 period - support domestic market concentration resulting in strategic international gains; hence, domestic airline alliances likely improve national welfare. 相似文献

Information Externalities,Neighborhood Characteristics and Home Mortgage Pricing and Underwriting 下载免费PDF全文
Theories of rational redlining suggest thinness in housing markets should lead to greater uncertainty in house price appraisals, increasing mortgage denial rates or pricing. Empirical tests found support for this theory in mortgage underwriting using 1990s data. Using 2006 data and bank‐specific regression models, we revisit this topic in light of two developments leading to the recent mortgage bubble: the widespread securitization that allowed banks to shift loan risk to investors and the advent of risk‐based pricing. Consistent with expectations, we find that information externalities have become economically very small and have shifted from underwriting to pricing decisions. 相似文献
