Market responses to legislative reforms often mitigate the expected gains that reformers promise in legislation. Contemporaries hailed workers' compensation as a boon to workers because it raised the amount of postaccident compensation paid to injured workers. Despite the large gains to workers, employers often supported the legislation. Analysis of several wage samples from the early 1900s shows that employers were able to pass a significant part of the added costs of higher postaccident compensation on to some workers in the form of reductions in wages. The size of the wage offsets, however, was smaller for union workers.

This paper investigates the link between the trend in the returns to education and foreign competition in concentrated industries. We argue that the impact of foreign competition on the relative wages of less skilled workers depends on the market structure of the industry penetrated. The empirical evidence indicates that employment changes in a small group of trade-impacted concentrated industries can explain not only part of the aggregate rise in wage inequality in the United States, but also some of the differences in the trends in wage inequality across metropolitan areas.
