The entry of married women into the labor force is one of the most notable economic phenomena of the twentieth century. We argue that medical progress played a critical role in this process. Improved maternal health alleviated the adverse effects of pregnancy and childbirth on women's ability to...

This paper investigates the effects of female labor supply on the wage structure. To identify variation in female labor supply, we exploit the military mobilization for World War II, which drew many women into the workforce as males exited civilian employment. The extent of mobilization was not...

This paper seeks to explain the greater hours worked by Americans compared to Germans in terms of forward-looking labor supply responses to differences in earnings inequality between the countries. We argue that workers choose current hours of work to gain promotions and advance in the...

Coal mining is a dangerous occupation where safety is an important output. Fatalities and disasters may change future accident costs at or near a mine. We use this variation to understand the tradeoffs between mineral output and safety. We find that government inspections and penalties increase...

We study how provider choice in workers' compensation cases affects costs and outcomes. When employees choose the provider, costs are higher and return-to-work outcomes are worse, while physical recovery is the same although satisfaction with medical care is higher. The higher costs and worse...
