The Wage Impact Of Teachers Unions: A Meta‐Analysis

Abstract

The literature examining the impact of teachers unions on education is very large and diverse. We meta‐analyze the literature on the wage impacts of teachers unions to try to draw out general findings, the importance of empirical model specification, and samples. A key finding of this study is that the average wage impact estimated by the included papers is modest, around 2%–4.5%. Our findings also suggest that the quality of an empirical strategy significantly affects the size of the estimated impact. We find that teachers union wage impacts have varied over time. The largest impacts appear to be following the rapid expansion of teacher unionism in the 1970s. Finally, we gain new insight into the goals of teachers unions by using the increased statistical power of meta‐analytic techniques to show that unions increase the wages of new teachers and not just senior teachers.
