DO STATE EMPLOYMENT ELIGIBILITY VERIFICATION LAWS AFFECT JOB TURNOVER?

State laws requiring employers to verify workers' employment eligibility may reduce employment and earnings among unauthorized workers and make it difficult for them to switch jobs. Using data from the 2005–2014 Quarterly Workforce Indicators, we find evidence of a reduction in employment and job turnover among Hispanics as a whole in states that require all employers to verify employment eligibility. These adverse effects become larger as the share of likely unauthorized Hispanic workers falls. The drop in job turnover may be due to the laws trapping some Hispanic workers in their jobs. There is little effect on employment or job turnover among non‐Hispanic whites or blacks. There is no effect on average pay for all groups of workers. (JEL J15, J61, J68)     

On the determinants of optimal border enforcement

We extend the current immigration-enforcement literature by incorporating both the practice of people smuggling and a role for non-wage income into a two-country, dynamic general equilibrium model. We use the model economy to examine three questions. First, how does technological progress in the smuggling industry affect the level of migration and capital accumulation for a given level of enforcement? Second, do changes in border enforcement affect the level of migration, capital accumulation, and smuggling activity? Third, is the optimal level of enforcement sensitive to technological progress in the smuggling industry? We show that the government chooses to devote resources to border enforcement only if the deterrent effect on smugglers is large enough. Otherwise, it is not worth taxing host-country natives as the taxes paid will more than offset any income gain resulting from fewer migrants.
