Mayer, Jochen; Riphahn, Regina T. (1998): Fertility Assimilation of Immigrants: A Varying Coefficient Count Data Model. Sonderforschungsbereich 386, Discussion Paper 140




This study presents the first econometric application of the Poisson varying coefficient (PVC) model. This count data model is applied to investigate immigrant fertility adjustment after migration. Data on completed fertility are taken from the 1996 wave of the German Socioeconomic Panel (GSOEP). We find evidence in favor of the assimilation model according to which immigrant fertility converges to native levels over time. Other determinants of completed fertility are marital history and female human capital, well in accordance with theoretical predictions.
