内容摘要:This paper considers the estimation of panel data models with interactive fixed effects where the idiosyncratic errors are subject to conditional quantile restrictions. I propose a two-step estimator for the coefficient of the observed regressors that is easy to implement in practice. In the first step, the principal component analysis is applied to the cross-sectional averages of the regressors to estimate the latent factors. In the second step, the smoothed quantile regression is used to estimate the coefficient of the observed regressors and the factor loadings jointly. The consistency and asymptotic normality of the estimator are established under large N, T asymptotics. It is found that the asymptotic distribution of the estimator suffers from asymptotic biases, and I show how to correct the biases using both analytical and split-panel jackknife bias corrections. Simulation studies confirm that the proposed es- timator performs well with moderate sample sizes.
