Medical care represents an important component of workers' compensation benefits with the potential to improve health and post-injury labor outcomes, but little is known about the relationship between medical care spending and the labor outcomes of injured workers. We exploit the 2003--2004 California workers' compensation reforms which reduced medical spending disproportionately for workers incurring low back injuries. We link administrative claims data to earnings records for injured workers and their uninjured coworkers. We find that workers with low back injuries experienced a 7.6 percent post-reform decline in medical care, and an 8.1 percent drop in post-injury earnings relative to other injured workers.

We document variation in working conditions in the United States, present estimates of how workers value these conditions, and assess the impact of working conditions on estimates of wage inequality. We conduct a series of stated-preference experiments to estimate workers’ willingness to pay for a broad set of working conditions, which we validate with actual job choices. We find that working conditions vary substantially, play a significant role in job choice, and are central components of the compensation received by workers. We find that accounting for differences in preferences for working conditions often exacerbates wage differentials and intensifies measures of wage inequality.
