Data on EU economies show no correlation between low-skilled immigration and the skill premium. We rationalise this evidence in a model where firms face search and screening costs. Low-skilled immigration diminishes the relative benefit of screening skilled workers, leading to a decline in their relative ability within the firm and an undetermined impact on the skill premium. On region-sector and firm level data from 2008 to 2013, we find that low-skilled immigration in Italian regions has reduced skill intensity without affecting the skill premium. Using proxies for workers’ ability and screening activity, we provide supporting evidence for the theorised mechanisms.
