Quantifications of the overall effects of Circular migration schemes on home countries are scant. This research paper draws upon a global integrated assessment model in order to provide some quantification of the possible effects of different types of circular migration patterns and compares them with traditional permanent migration. In the simulations for four countries (Sierra Leone, Ghana, Vietnam and Moldova), research results suggest circular migration programmes yield better outcomes than permanent migration due to the productivity gains induced in the home countries by returning migrants.
