The use of factor-augmented panel regressions has become very popular in recent years. Existing methods for such regressions require that the common factors are strong, an assumption that is likely to be mistaken in practice. Motivated by this, the current article offers an analysis of the effect of weak, semi-weak, and semi-strong factors on two of the most popular estimators for factor-augmented regressions, namely, principal components (PC) and common correlated effects (CCE). 相似文献

We conduct an experiment with professional internal auditors and evaluate their performance and objectivity, measured as the extent to which they truthfully report the performance of other participants in a real-effort task. In line with our hypotheses, we find that incentive-based compensation increases dishonest behavior: competitive incentives lead to under-reporting of other participants' performance, while collective incentives lead to over-reporting of performance. We replicate these results with a student sample. In addition, we find that moving from an environment with objective performance evaluation toward a peer evaluation scheme reduces performance among internal auditors, but not among students.(JEL C93, M42, M52) 相似文献

Meta-analysis using multilevel models with an application to the study of class size effects 总被引:1,自引:0,他引:1
Harvey Goldstein Min Yang Rumana Omar Rebecca Turner & Simon Thompson 《Journal of the Royal Statistical Society. Series C, Applied statistics》2000,49(3):399-412
Meta-analysis is formulated as a special case of a multilevel (hierarchical data) model in which the highest level is that of the study and the lowest level that of an observation on an individual respondent. Studies can be combined within a single model where the responses occur at different levels of the data hierarchy and efficient estimates are obtained. An example is given from studies of class sizes and achievement in schools, where study data are available at the aggregate level in terms of overall mean values for classes of different sizes, and also at the student level. 相似文献

This paper contributes to the existing literature by evaluating the effects of age and tenure on careers and productivity within an internal labor market. We use the administrative personnel records of a long balanced panel of blue-collar workers from a manufacturing firm in Germany with a distinct classification of wage groups and unique information on workers’ productivity in form of suggestions for productivity improvement. Using robust locally weighted regression, our main findings suggest that the probability of promotion is highest for younger workers and early in the career. Older workers are less likely to be promoted. The likelihood of making a rewarded suggestion is inversely u-shaped with respect to tenure and age. Furthermore, workers’ ability and firm-specific human capital determine the workers’ careers and productivity. 相似文献

Modelling the effect of pupil mobility on school differences in educational achievement 总被引:1,自引:1,他引:0
Harvey Goldstein Simon Burgess Brendon McConnell 《Journal of the Royal Statistical Society. Series A, (Statistics in Society)》2007,170(4):941-954
Summary. The recently introduced national pupil database in England allows the tracking of every child through the compulsory phases of the state education system. The data from key stage 2 for three local education authorities are studied, following cohorts of pupils through their schooling. The mobility of pupils among schools is studied in detail by using multiple-membership multilevel models that include prior achievement and other predictors and the results are compared with traditional 'value-added' approaches that ignore pupil mobility. The analysis also includes a cross-classification of junior and infant schools attended. The results suggest that some existing conclusions about schooling effects may need to be revised. 相似文献
