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 …

This study analyzed the nonlinear impacts of education, particularly higher education, on
economic growth in the ASEAN-5 countries (ie, Thailand, Indonesia, Malaysia, Singapore …

The aim of this study is to investigate the relationship between green technology R&D
investment and corporate performance (ROA) of 44 Beijing-listed energy companies from …

We consider estimation and inference for a regression coefficient in panels with interactive
fixed effects (ie, with a factor structure). We show that previously developed estimators and …

The analysis of energy use not only sheds light on lightening the increasing pressures from
energy systems but also improves the flexibility and reliability of power systems. As the …

Revolutionary agricultural structural reforms in the supply chain and cutting-edge
institutional mechanisms are pivotal in catalyzing a quantum leap in food production …

This paper addresses statistical inference for high-dimensional threshold regression
parameters. I establish oracle inequalities for the scaled LASSO estimator proposed by Lee …

This paper introduces a factor-augmented forecasting regression model in the presence of
threshold effects. We consider least squares estimation of the regression parameters and …

This paper introduces unit-specific heterogeneity in panel data threshold regression. Both
slope coefficients and threshold parameters are allowed to vary by unit. The heterogeneous …

This paper develops a new simple method to simultaneously test the threshold effect and the
correlation between unobserved individual effects and covariates in a panel ordered …
