Inward and Outward Migration under Shifting Legal-Democratic Regimes

This paper analyzes the two-way relationship between international migration and political regime change, highlighting a feedback loop in which political shifts shape migration flows, while migration itself reshapes political trajectories. Relying on a Difference-in-Differences (DiD) framework and a dataset combining migration flows, regime quality indicators (CHRI), and measures of international integration, we identify three central results.
First, substantial immigration into politically fragile democracies undermines institutional quality. The 2015 Syrian shock provides a particularly valuable exogenous case: a sudden, large-scale refugee inflow that bypassed domestic policy controls and provoked sharp political responses, allowing for clearer identification of immigration’s institutional effects. Second, democratic decline increases emigration, draining human capital and further weakening prospects for democratic recovery. Third, international integration—most notably through EU accession—conditions these dynamics, amplifying or dampening the outflow response to political change.
Taken together, these findings show that migration is not merely a symptom of political instability but also a driver of institutional transformation, simultaneously reinforcing and accelerating regime shifts toward illiberalism.
