Abstract
This dissertation studies the welfare and production effects of immigration and international trade, and how the two effects interact in the globalized economy. In Chapter I, Xing Guo and I study how the U.S. restrictions on skilled immigration affect the Canadian economy and the welfare of American workers. In 2017, there was a policy that tightened the eligibility criteria for U.S. visas and was immediately followed by a trend break in the number of skilled immigrant admissions to Canada. We use quasi-experimental variation introduced by this policy over time and across immigrant groups, along with U.S. and Canadian visa application data, to show that Canadian applications in 2018 were 30% larger than without the restrictions. We then study how the restrictions affected Canadian firms using comprehensive Canadian administrative databases containing the universe of employer-employee-linked records, immigration records, and international trade data. We find that the restrictions increased firms’ production, exports, and employment of Canadian workers. Finally, we study the policy’s impact on American workers by incorporating immigration policy into a multi-sector international trade model. With international trade, the increase in immigration to other countries due to the restrictions affects American wages through U.S. exports and consumption prices. We calibrate the model using our novel data and reduced-form estimates. We find that the welfare gains for American workers targeted for protection by the 2017 policy are up to 25% larger in a closed economy than in an open economy with the observed trade levels. In Chapter II, Nicolas Morales and I use a detailed establishment-level dataset from Germany to document that large firms allocate a higher proportion of their wage bill to immigrants compared to small firms. We study both analytically and quantitatively the importance of this heterogeneity across firms in the effects of immigration on the welfare of native-born workers. To achieve this, we set up and estimate a model of international trade and immigration where heterogeneous firms choose their immigrant share. Two new adjustment mechanisms arise when firms have heterogeneous immigrant shares. First, native workers reallocate across firms towards firms that are less immigrant-intensive, which mitigates the competition effect between immigrants and natives in the labor market. Second, the gains are largely concentrated among the largest and most productive employers, which induces an additional aggregate productivity gain. We find that our model with no heterogeneity in immigrant share across firms underestimates the native workers’ welfare gains by 11%. In chapter III, Alberto Cavallo, Javier Cravino, Andres Drenik and I study how the price of remote work is determined in a globalized labor market using data from a large web-based job platform, where workers from around the world compete for remote jobs. Despite the global nature of the platform, we find that remote wages are higher for workers in regions with higher income per capita. This correlation is not accounted for by differences in workers’ observable characteristics, occupations, or differences in the employers’ locations. Instead, data on wage histories indicate that remote wages are partly determined by the conditions that workers face in their local labor markets. We also show that remote wages expressed in local currency move strongly with the dollar exchange rate of the worker’s country and are highly sensitive to foreign competition. Finally, we identify occupations at high risk of being offshored based on the prevalence of cross-border contracts.
