The labour market return to permanent residency

Many temporary foreign worker programs issue "closed" visas that effectively tie workers to a single employer, restricting worker mobility and weakening bargaining power. We study the labor market return to temporary foreign workers (TFWs) gaining permanent residency (PR), which loosens this mobility restriction. Using administrative data linking matched employer-employee data in Canada to temporary and permanent visa records from 2004-2014 along with an eventstudy design, we find that gaining PR leads to a sharp, immediate, and persistent increase in the job switching rate of 21.7 percentage points and an increase in earnings of 5.7 percent three years after PR. Workers also sort into high-wage firms after gaining PR, and the increase in the firm pay premium is roughly 56 percent of the total earnings gain. We find larger earnings gains for job switchers across industries, low-skilled workers, and workers from low-income countries. To guide and interpret our reduced-form results, we develop a search-and-matching model featuring heterogeneous workers and firms. Permanent residents and native-born workers search for jobs in the same labor market and engage in on-the-job search, while TFWs search separately within a segmented labor market and do not receive outside wage offers. We calibrate the model to match our reduced-form results, and we use it to simulate the long-run effects of PR and consider two counterfactual policies: (1) increasing the cost to firms of posting a TFW vacancy and (2) allowing TFWs to switch employers freely under "open" visas. We evaluate how these policies affect output, wages, profits, and overall social welfare.
