We evaluate the impact of the Washington State Attorney General's enforcement campaign against employee no-poaching clauses in franchising contracts, which unfolded from 2018 through early 2020. Implementing a staggered difference-in-differences research design using Burning Glass Technologies...

Using data on the near-universe of online US job vacancies collected by Burning Glass Technologies in 2016, we calculate labor market concentration using the Herfindahl-Hirschman index (HHI) for each commuting zone by 6-digit SOC occupation. The average market has an HHI of 3,953, or the...

The relationship between competition and innovation is difficult to disentangle, as exogenous variation in market structure is rare. The 1952 breakup of Germany's leading chemical company, IG Farben, represents such a disruption. After the Second World War, the Allies occupying Germany imposed...

A product market is concentrated when a few firms dominate the market. Similarly, a labor market is concentrated when a few firms dominate hiring in the market. Using data from the leading employment website CareerBuilder.com, we calculate labor market concentration for over 8,000...

This chapter reviews the literature on employment and labor law. The goal of the review is to understand why every jurisdiction in the world has extensive employment law, particularly employment protection law, while most economic analysis of the law suggests that less employment protection...

Graduating from a school during a time of adverse economic conditions has a persistent, harmful effect on workers' subsequent employment opportunities. An analysis of panel data from OECD countries during the 1960-2010 periods reveals that a worker who experiences a one-percentage-point higher...

This chapter investigates the impact of the imposition of sanctions for employing illegal migrants on the welfare of native laborers. In response to such sanctions, managers in a firm may be reassigned from the supervision of production to the verification of the legality of the firm's labor...

How does enforcement of labor regulations shape the labor market effects of trade? To tackle this question, we exploit the Brazilian trade liberalization episode and exogenous variation in the intensity of both the trade shock and enforcement across local labor markets. Regions with stricter...

The existing literature investigating the labor market impact of immigration assumes, implicitly or explicitly, that the law or labor regulation is exogenous to immigration. To test this assumption, we build a novel workers' protection measure based on 36 labor law variables that capture labor...

Drawing upon data from the largest cross-country study of labor market concentration to date, this paper analyzes the level of concentration of labor input markets in Europe and North America and provides a comparative perspective on employers' monopsony power. It explores the characteristics of...
