Title: What has mattered to economics since 1970
Description: "We compile the list of articles published in major refereed economics journals during the last 35 years that have received more than 500 citations.  We document major shifts in the mode of contribution and in the importance of different sub-fields: Theory loses out to empirical work, and micro and macro give way to growth and development in the 1990s.  While we do not witness any decline in the primacy of production in the United States over the period, the concentration of institutions within the U.S.  hosting and training authors of the highly-cited articles has declined substantially"--National Bureau of Economic Research web site.
