Abstract
In this paper I address four questions concerning the quality of scientific economic papers. First, I validate the ex-ante procedure of computing the average impact of economic papers by comparing its results with the expost values. Second, I calibrate an estimator of papers normalised impact. Third, I compute the ranking variability of journals using a bootstrap procedure. Fourth, I test the statistical hypothesis that journals’ ranking did not changed over the time interval between 1980 and 2000. I concluded that this hypothesis is rejected only for the ‘Quarterly Journal of Economics’ and ‘Econometrica’, which saw their citation impact improved.
