As bankers’ pay, at least for the fortunate ones at Goldman and JPMorgan, returns to pre-crisis heights, a paper by Thomas Philippon and Ariell Reshef is becoming everyone’s favorite citation. The paper, “Wages and Human Capital in the U.S. Financial Industry: 1909-2006,” got a first wave of attention from Paul Krugman, Martin Wolf, and Gillian Tett back in April (see Philippon’s web page for links). It’s also the subject of Justin Fox’s column in Time; see Fox’s blog for links to other discussions. (I also cited the paper in my ramblings provoked by Calvin Trillin.) The earlier references were mainly for Philippon and Reshef’s finding that pay in the financial sector correlated strongly and negatively with the degree of regulation — pay was higher in both the 1920 and in the post-1980 period, and lower under the stricter regulatory system created during the Great Depression. More recent references, including Fox’s column, have focused on the idea that people in finance are overpaid.
Since most articles have just focused on the headlines, I’m sure Philippon and Reshef are going to be misquoted all over the Internet. For example, at least two articles focus on a figure of “30% to 50% of financial-sector pay” in ways that are not quite correct. So I’ll try to lay out what they actually say.
