This study aims to explore the non-linear renewables and carbon emission efficiency (CEE)
nexus to optimize the energy transition path. Taking 32 developed countries that have …

How to improve environmental quality and achieve human development remains major
sustainability issues, particularly in the MENA region (the Middle East and North Africa) …

We study discrete panel data methods where unobserved heterogeneity is revealed in a first
step, in environments where population heterogeneity is not discrete. We focus on two‐step …

In this paper, we study the least squares (LS) estimator in a linear panel regression model
with unknown number of factors appearing as interactive fixed effects. Assuming that the …

We analyze linear panel regression models with interactive fixed effects and predetermined
regressors, for example lagged-dependent variables. The first-order asymptotic theory of the …

This paper studies panel data models with interactive fixed effects where the regressors are
allowed to be correlated with the idiosyncratic error terms. We propose a two-step profile …

We consider the problem of determining the number of factors and selecting the proper
regressors in linear dynamic panel data models with interactive fixed effects. Based on the …

This paper provides estimation and inference methods for conditional average treatment
effects (CATE) characterized by a high‐dimensional parameter in both homogeneous cross …

We study linear panel regression models in which the unobserved error term is an unknown
smooth function of two-way unobserved fixed effects. In standard additive or interactive fixed …

This paper develops a new minimum distance quantile regression (MD-QR) estimator for
panel data models with fixed effects. The proposed estimator is efficient in the class of …
