The Long-Run Effects of Teacher Collective Bargaining

We analyze how exposure to teacher collective bargaining affects long-run outcomes for students, exploiting the timing of state duty-to-bargain law passage in a cross-cohort difference-in-difference framework. Among men, exposure to a duty-to-bargain law in the first 10 years after passage depresses annual earnings by $2,134 (3.93 percent), decreases weekly hours worked by 0.42, and reduces employment and labor force participation. The earnings estimate implies that current duty-to-bargain laws reduce earnings by $213.8 billion annually. Effects grow with time since law passage, are largest among nonwhites, and are not evident for women. Duty-to-bargain laws reduce male noncognitive skills, supporting the labor market findings.
