Who leaves and when? : selective outmigration of immigrants from Germany

This paper provides new evidence on the outmigration behaviour of foreign-born immigrants. Our analysis is based on data from the German Socio-Economic Panel covering the period 1984 to 2010. A unique feature of our paper is the use of new data from panel-drop out studies, which allows us to identify outmigration. As statistical technique, we employ penalized spline smoothing in the context of a Poisson-type Generalized Additive Mixed Model (GAMM), which enables us to incorporate bivariate interaction effects. For Non-Turkish immigrants we find a u-shaped pattern between human capital endowment and outmigration. For Turkish immigrants, outmigration is characterized by a positive self-selection with respect to skill intensifying the initial negative selection process. In addition to this, family characteristics have strong effects on emigration decisions. Finally, our results highlight substantial variation in outmigration behaviour during the life cycle. -- Emigration ; Self-selection ; German Socio-Economic Panel ; Generalized Additive Mixed Models ; Penalized Splines
