This course focuses on the economics of international migration. In the first part of the class we will analyze the impact of immigration on destination countries. We will consider several economic channels, which include the labor market, the welfare state (fiscal effects), price effects and the impacts of immigration on trade and FDI flows. We will also investigate the non-economic effects of immigration, from a cultural, crime and political point of view. In the second part of the class we will examine the determinants of international migration. Among them, we will single out migration policies of destination countries. We will develop a political-economy model of migration policy and investigate its components, in particular public opinion on migration and the role of interest groups. We will also investigate the impact of immigration on election outcomes.
