Code for: The Impact of Unions on the Wage Distribution: Evidence from Higher Education

We estimate the impact of unionization on the wage
distribution of Canadian university faculty using longitudinal administrative
data on salaries and exploiting the staggered rollout of unionization across
institutions. We find that unionization compressed salaries: wages at the
bottom of the unconditional distribution increased by roughly 10 percent while
wages at the top were unaffected. Our evidence suggests that these
distributional impacts were driven by the introduction of contractual salary
floors. We also estimate little impact of unionization on faculty employment.
Instead, our results suggest that the increase in universities’ wage bills was
financed by an increase in student enrollment.
