with the idiosyncratic error terms. We propose a two-step profile GMM estimation procedure to estimate the parameters of …-norm-regularization (NNR) based profile GMM procedure. In the second step, via an iterative procedure, we conduct post-NNR profile GMM … estimation of the slope coefficient, factors, and factor loadings, with an improved convergence rate for the estimate of the …
