Panel data in environmental economics: Econometric issues and applications to IPAT models
讨论了环境经济学中IPAT模型等面板数据分析面临的非平稳性和截面相关等计量问题,指出标准方法可能导致有偏估计和错误推断,并提供了实用指南。
This paper addresses econometric challenges arising in panel data analyses related to IPAT (environmental Impact of Population, Affluence and Technology) models and other applications typically characterized by a large-N and large-T structure. This poses specific econometric complexities due to nonstationarity and cross-sectional error correlation, potentially affecting consistent estimation and valid inference. We provide a concise overview of these complications and how to deal with these with appropriate tests and models. Moreover, we apply these insights to empirical examples based on the IPAT identity, offering insights into the robustness of previous findings. Our results suggest that using standard panel techniques can lead to biased estimates, incorrect inference, and invalid model adequacy tests. This can potentially lead to flawed policy conclusions. We provide practical guidance to practitioners for navigating these econometric issues.
