Léa MARCHAL, Giulia SABBADINI, Immigrant Workers, Firm Export Performance and Import Competition – Submitted.
Abstract: This paper investigates whether the employment of immigrant workers affects the performance of firms in their export markets when they are facing an increase in import competition. Exploiting the surge of Chinese imports following its accession to the World Trade Organization and using a sample of French manufacturing exporters from 2002 to 2015, we find that an increase in the growth rate of Chinese imports in a market has a negative effect on both the survival probability of firms and the growth rate of sales on that market. This negative effect on firm performance is mitigated by the employment of immigrant workers.

Amandine AUBRY, Jérôme HÉRICOURT, Léa MARCHAL, Clément NEDONCELLE, Does Immigration Affect Wages? A Meta-Analysis – Submitted.
Abstract: Does immigration deter native wages? No decisive answer has been provided until now. We provide an up-to-date meta-analysis of the literature investigating this topical question, based on 2,146 estimates from 64 studies published between 1972 and 2019. We confirm the average effect of immigration on native wages is negative and close to zero. This average effect hides a large heterogeneity across studies. Variation across estimates can be explained by the presence of structural heterogeneity such as the country of analysis, whereas little variance can be attributed to heterogeneity in research designs. Finally, on top of these structural determinants, we estimate a strong,robust, and negative effect of publishing in leading academic journals.

Léa MARCHAL, Guzmán OURENS, Giulia SABBADINI, When Immigrants Meet Exporters: A Reassessment of the Immigrant Wage Gap – In progress.
Abstract: We use French employer-employee data for the manufacturing sector from 2005 to 2012 to reassess the wage gap between native and foreign workers. In line with previous evidence, we find that immigrants earn less than natives and that exporters pay higher wages. New in this literature, we find that the nativity wage gap varies with the export intensity of the firm and the occupational group of the worker within the firm. We present a model with heterogeneous firms and workers to show that our findings are consistent with white-collar immigrant workers capturing an informational rent, as they provide exporters with valuable information to access foreign markets. We provide empirical evidence for this mechanism by analysing how the nativity wage gap varies with the complexity of firm export activity and with the group of origin of the immigrant workers.
