The New Yorker:

In 2016, the highest-paid employee of the State of California was Jim Mora, the head coach of U.C.L.A.’s football team. (He has since been fired.) That year, Mora pulled in $3.58 million. Coming in second, with a salary of $2.93 million, was Cuonzo Martin, at the time the head coach of the men’s basketball team at the University of California, Berkeley. Victor Khalil, the chief dentist at the Department of State Hospitals, made six hundred and eighty-six thousand dollars; Anne Neville, the director of the California Research Bureau, earned a hundred and thirty-five thousand dollars; and John Smith, a seasonal clerk at the Franchise Tax Board, earned twelve thousand nine hundred dollars.

I learned all this from a database maintained by the Sacramento Bee. The database, which is open to the public, is searchable by name and by department, and contains precise salary information for the more than three hundred thousand people who work for California. Today, most state employees probably know about the database. But that wasn’t the case when it was first created, in 2008. This made possible an experiment.

The experiment, conducted by four economists, was designed to test rival theories of inequity. According to one theory, the so-called rational-updating model, people assess their salaries in terms of opportunities. If they discover that they are being paid less than their co-workers, they will “update” their projections about future earnings and conclude that their prospects of a raise are good. Conversely, people who learn that they earn more than their co-workers will be discouraged by that news. They’ll update their expectations in the opposite direction.
