Using the recent China Family Panel Studies, we are able to identify the subjects studied of both college (2-3 years) graduates and university (4-5 years) graduates. For the latter group, we can further distinguish universities by the tier of selectivity (i.e. Key and Ordinary Universities). We...

Using the recent China Family Panel Studies, we identify the subjects studied by college (2-3 years) graduates and university (4-5 years) graduates. For the university graduates, we can further distinguish universities by the tier of selectivity (i.e., Key and Ordinary Universities). We take...

In this paper, we propose a variable selection procedure based on the shrinkage estimation technique for a categorical varying-coefficient model. We apply the method to identify the relevant determinants for body mass index (BMI) from a large amount of potential factors proposed in the...

In this paper, we consider a partially linear panel data model with cross-sectional dependence and non-stationarity. Meanwhile, we allow fixed effects to be correlated with the regressors to capture unobservable heterogeneity. Under a general spatial error dependence structure, we then establish...

This paper considers a model with general regressors and unobservable factors. An estimator based on iterated principal components is proposed, which is shown to be not only asymptotically normal and oracle efficient, but under certain conditions also free of the otherwise so common asymptotic...
