The Migration Trade-off — Labour Markets and Borders

Three-round policy simulation set in two fictional twin economies (Costaria and Boravia). Participants compute the four standard welfare effects of a migration flow (aggregate output, native wages, migrant welfare, remittances), assign explicit welfare weights across stakeholders, layer in second-order effects (fiscal balance, housing, brain drain, integration), and design a defensible migration policy from eight archetypes — required to defend it on its weakest panel, not just its strongest.
