High- and low-wage occupations are expanding rapidly relative to middle-wage occupations in both the U.S. and the E.U. We study the reallocation of workers from middle-skill occupations towards the tails of the occupational skill distribution by analyzing changes in age structure within and...

We juxtapose the effects of trade and technology on employment in U.S. local labor markets between 1990 and 2007. Labor markets whose initial industry composition exposes them to rising Chinese import competition experience significant falls in employment, particularly in manufacturing and among...

This paper investigates how job creation and destruction behavior varies by employer size in the U.S. manufacturing sector during the period 1972 to 1988. The paper also evaluates the empirical basis for conventional claims about the job-creating prowess of small businesses. The chief findings...

Employment rates in Puerto Rico range from 55 to 65 percent of U.S. rates during the past thirty years. This huge employment shortfall holds for men and women, cuts across all education groups, and is deeper for persons without a college degree. The shortfall is concentrated in the private...

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...

Theory predicts that mandated employment protections may reduce productivity by distorting production choices. Firms facing (non-Coasean) worker dismissal costs will curtail hiring below efficient levels and retain unproductive workers, both of which should affect productivity. These theoretical...

The U.S. temporary help services (THS) industry grew at 11 percent annually between 1979 to 1995, five times more rapidly than non-farm employment. Contemporaneously, courts in 46 states adopted exceptions to the common law doctrine of employment at will that limit employers' discretion to...

Many theoretical models of labor market search imply a tight link between worker flows (hires and separations) and job gains and losses at the employer level. Partly motivated by these theories, we exploit establishment-level data from U.S. sources to study the relationship between worker flows...
