Notes: Lines show the predicted change in earnings for a 1 percentage-point increase in unionization. The sample is restricted to nonunion, full-time workers in the private sector ages 16 to 64. Wages are measured in 2013 dollars. See the text and Methodological Appendix for details on the analysis.
