The entire distribution of number of authors has shifted steadily rightward. In the last two decades the fraction of older authors has almost quadrupled. The top journals are now publishing many fewer papers that represent pure theory, regardless of sub-field, somewhat less empirical work based on publicly available data sets, and many more empirical studies based on data assembled for the study by the author(s) or on laboratory or field experiments.
