This paper proposes new ℓ1-penalized quantile regression estimators for panel data, which explicitly allows for … the techniques to two empirical studies. First, the new method is applied to the estimation of labor supply elasticities …

A panel data set covering 145 countries between 1960 and 2010 has been investigated closely by using models of … determinants, dependent on one or both status variables in a local estimation. Afterwards, the well-known Solow (1956) model serves …

We investigate a nonparametric panel model with heterogeneous regression functions. In a variety of applications, it is …

estimation with panel data illustrates the results. …This paper considers identification and estimation of ceteris paribus effects of continuous regressors in nonseparable … panel models with time homogeneity. The effects of interest are derivatives of the average and quantile structural functions …
