Shifts in the employment outcomes among Mexican migrants to the United States, 1976–2009

Although studies have examined the impact of U.S. immigration policy shifts in the 1980s and 1990s on the employment outcomes of migrants, scholars have paid less attention to how the federal government's shifting approach to worksite enforcement has transformed the conditions in which Mexican migrants work. Consistent with previous research, we find a worsening of conditions for both unauthorized and legal Mexican migrants in the years following the passage of the Immigration Reform and Control Act (IRCA) and that unauthorized status is associated with more unfavorable workplace conditions relative to legal immigrants. However, in the first decade of the 21st century, we also find that unauthorized immigrants’ employment outcomes more closely resemble those of legal immigrants now than in the past, suggesting a dramatic shift in the ways that employers treat unauthorized immigrants on the job. This convergence between authorized and unauthorized migrants is consistent with federal policies and practices related to workplace enforcement.
