Billions of dollars are allocated every year to university research. Increased specialisation and international integration of research and researchers has sharply raised the need for comparisons of performance across fields, institutions and individual researchers. However, there is still no...

We study to what degree authors who publish in the five most prestigious journals in economics have previously published there and in which world region they are based. Al­though still high, the concentration of U.S.-based and previously published top-five authors has decreased. This trend is...

This paper presents a meta-analysis of the "cluster literature" contained in scientific journals from 1969 to 2007. Thanks to an original database we study the evolution of a stream of literature which focuses on a research object which is both a theoretical puzzle and an empirical widespread...

A meta-analysis (MA) aggregates estimated effects from many studies to calculate a single, overall effect. There is no one, generally accepted procedure for how to do this. Several estimators are commonly used, though little is known about their relative performance. A complication arises when...

Journals favor rejection of the null hypothesis. This selection upon tests may distort the behavior of researchers. Using 50,000 tests published between 2005 and 2011 in the AER, JPE, and QJE, we identify a residual in the distribution of tests that cannot be explained by selection. The...

This study uses Monte Carlo analysis to investigate the performances of five different meta-analysis (MA) estimators: the Fixed Effects (FE) estimator, the Weighted Least Squares (WLS) estimator, the Random Effects (RE) estimator, the Precision Effect Test (PET) estimator, and the Precision...
