Electoral Systems, Taxation and Immigration Policies: Which System Builds a Wall first? (with Massimo Morelli)
When exposed to similar migration flows, countries with different institutional systems may respond with different levels of openness. We study in particular the different responses determined by different electoral systems. We find that Winner Take All countries would tend to be more open than countries with PR when all other policies are kept constant, but, crucially, if we consider the endogenous differences in redistribution levels across systems, then the openness ranking may switch.
