Regulating Labor Immigration: The Effects of Lifting Labor Market Testing

Labor market testing (LMT) requires firms to demonstrate there are no local work-ers available before hiring an immigrant. We examine the effect of removing LMT requirements for non-EU workers in Finland utilizing regional and temporal vari-ation in occupations exempted from LMT. We combine individual and firm-level administrative data with hand-collected information on local changes in labor market testing rules and apply a staggered difference-in-differences research design. We find that removing the LMT requirement increases the inflow of non-EU workers to treated occupation-region cells. This is mainly driven by non-EU individuals already in Finland. Five years post-treatment, the negative earnings effect is 2 % at the occupation-region level and 4% for incumbent workers at the individual level, more pronounced in low-wage and service-oriented occupations and among older workers. In low-paying occupations, the earnings effect is largely attributable to decreased working hours and to a suppressed wage drift for stayers. However, we also observe a positive employment effect at the individual level for workers in the upper segment of the wage distribution. At the firm level, LMT removal increases the number of non-EU employees while having no effect on profitability.
