For whatever it is worth, there are recent rankings of economists
. The rankings examines economists from 1969 to 2000. There are four UCLA Ph.D.'s noted on the list: Ross Levine, Guido Tabellini, Bob Topel, and myself. Personally, I am honored to even be roughly on the same list as these three guys. Based on that ranking in terms of total academic journal output adjusted for quality of the journals I am ranked during that period of time as 26th (obviously I didn't get my Ph.D. until 1984 so that works to lower my rating relative to older economists, still I am surprisingly ahead of older well-known economists such as Robert Barro (Harvard), Ed Lazear (Stanford), and Peter Diamond (MIT) (see Table 8)). In terms of raw number of equivalent size pages in academic journals, I am 4th among all economists worldwide. Based upon citations during the 1969 to 2000 period I am 86th (putting me slightly ahead of older people such as John Roberts (Stanford), Ben Bernanke (Princeton, now head of the Federal Reserve), and Oliver Hart (MIT) (see Table 9)).
Thanks to Butch Browning for bringing this to my attention.
