A new analysis released by the National Bureau of Economic Research (abstract available here ) tracks the changes among the five leading economics journals from 1970 to 2012. Among the trends over that time span:
- Annual submissions to the top-5 journals nearly doubled.
- The total number of articles published declined from 400 per year to 300 per year.
- One journal, American Economic Review, now accounts for 40 percent of publications among these five publications, up from 25 percent.
- Papers are on average three times longer.
