Migration today presents challenges as well as opportunities. Few decisions can change livelihoods as much as the choice to relocate. The department’s work aims to answer questions in migration research that are at the frontier of scientific knowledge: How do individuals weigh the costs and benefits of migration? While it is commonly assumed that rising income levels initially increase the likelihood of migration, we examine how improved entrepreneurial prospects and employment opportunities resulting from training programs or infrastructure development affect the decision to migrate. At the same time, we examine the structural effects that migration have on regions and countries from which people migrate.
