Inequality and Migration

International migration is on the rise. In a period of less than 50 years, the stock of migrants has been multiplied by more than 3. This general phenomenon of massive movements of people nevertheless conceals quite an heterogeneous picture in terms of sending and receiving countries. In this lecture by Prof. Michel Beine, starting from the idea that every move starts with plans, we provide new explanation of that heterogeneity using data from the Gallup World Survey. We argue that these data contain useful information to predict future migration flows. We show that the data can shed some light on the way individuals perceive their own but also the foreign country.
