چکیده
Although sample selection bias is a frequent problem of applied research, there has been no generalization of sample selection models with binary dependent variables of interest to data with temporal error correlations. We suggest a generalized estimating equation (GEE) approach to panel data selection models, considering binary responses in both equations. We demonstrate the utility of this model by a simulation study and by analyzing highly unbalanced annual panel data taken from the German Socio-Economic Panel Study (SOEP) covering two decades of Green party support. ∗University of Hamburg, FB Psychology, Von-Melle-Park 5, 20146 Hamburg, Germany, email: [email protected] †German Institute for Economic Research (DIW Berlin), Mohrenstrasse 58, 10117 Berlin, Germany, email: [email protected]
