Presenting data on all full-length articles published in the three top general economics journals for one year in each of the 1960s through 2010s, I analyze how patterns of co-authorship, age structure and methodology have changed, and what the possible causes of these changes may have been.

A new paper by Daniel Hammermesh. He examines the QJE, AER and JPE.

Authors are getting older. And now just 87.4% male dominated instead of 95.3%!



And apparently we are getting more empirical but less likely to use existing data (in spite of the Internet!).
