"I use a large merger to study the effects of a concentration on labor market outcomes. I find that concentration lowers wages, but the effects are different than prior estimates in the literature. I observe a larger reduction in wages of salespeople (low skill) than pharmacists (high skill). Two hypotheses can explain the results: (i) salespeople have strong preferences for jobs or accumulate some industry-specific human capital, and (ii) pharmacists are better organized into unions. Previous studies do not account for changes in labor force composition that are relevant after a merger, which could explain the difference in estimates. I show that changes in labor force composition within establishments are common in the economy over time. "
