In an op-ed for Project Syndicate, Initiative Co-Director Daron Acemoglu weighs in on recent debates regarding high-skilled immigration and the H-1B program. He argues that although high-skilled workers have been shown to bring skills, knowledge, and innovation, increasing their number would still have costs. Namely, the presence of high-skilled workers may shape the direction of innovation, impact the incentives faced by domestic education systems, and could harm source countries via brain drain.
