RT Journal Article SR Electronic T1 Employers’ Language Proficiency Requirements and Hiring of Immigrants JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 1223-13300R3 DO 10.3368/jhr.1223-13300R3 A1 Carlsson, Magnus A1 Eriksson, Stefan A1 Rooth, Dan-Olof YR 2026 UL http://jhr.uwpress.org/content/early/2026/01/07/jhr.1223-13300R3.abstract AB Labor markets in advanced economies have undergone substantial change due to globalization, technological improvements, and organizational changes, making language proficiency increasingly important even in less skilled jobs. Has this development led employers to shy away from hiring immigrants with limited host-country language skills? We shed light on this question by conducting a large-scale field experiment, where we introduce common second-language features in immigrants’ resumes. We also conduct employer surveys to interpret our experimental results. Our main finding is that language proficiency has a strong positive effect on being invited to a job interview, even in typical immigrant entry jobs.
