A committee of distinguished economists have selected the top 20 articles published in the AER over the last 100 years. Hayek's "Use of Knowledge" is listed, as is Alchian and Demsetz's "Production, Information Costs, and Economic Organization". Grossman and Stiglitz's paper on the impossibility of informationally efficient markets is listed, as is Krueger's political economy of rent-seeking.
What do you think the list signals about what is, and what isn't important in the modern evolution of economic thinking?
What articles from the AER would you nominate?
