Is There Really a Faculty Union Salary Premium?
Department or Administrative Unit
Studies of the effects of unions on collegiate faculty salaries are inconclusive. Some estimate a significant union premium, but such estimates suffer from endogeneity between unions and wages, non-random measurement error, and failure to adjust for local cost-of-living differences. By using data from the National Study of Postsecondary Faculty (NSOPF, 1988–2004) as well as other sources to identify institution-specific factors omitted from previous studies, the authors estimate significantly smaller union premia than those found by other researchers.
