Beyond the EKC: Economic development and environmental degradation in the US
使用小波分位数相关方法分析美国1992-2022年数据，发现经济发展与环境退化之间存在短期负相关和长期正相关的复杂关系，不支持环境库兹涅茨曲线假说。
The paper explores the impact of economic development on environmental degradation in the United States of America (US) using a Wavelet Quantile Correlation (WQC) methodology proposed by Kumar and Padakandla (2022) . The span covers the period 1992M1-2022M12. The analysis does not confirm the Environmental Kuznets Curve (EKC) hypothesis in the US, offering short-term and long-term perspectives of the ‘economic development - environmental degradation’ nexus as a novelty. The core findings show a strong link between economic development and environmental degradation in the US, with short-term patterns exhibiting a negative sign in inverted-S and S shapes. Long-term patterns, however, display a positive sign in S and inverted-S shapes. These results remain robust across different gas types but with a time-delay effects due to molecular differences and their respective impacts on climate and environmental health .
