This paper aims to examine the impact of geopolitical risk (GPR), threats (GPT) and acts (GPA) on returns and volatilities of regional climate change stocks under different market conditions, employing quantile regressions. Our main results suggest that climate change stock returns positively (negatively) respond to GPR in bullish (bearish) market states, however the effect is not uniform across the regions. The volatilities mainly show a positive response to geopolitical tensions; geopolitical acts appear to have a more pronounced impact on volatilities than geopolitical threats. We further find that GPR leads to higher volatility during the Russia-Ukraine war, creating heightened uncertainty. Overall, the results reveal that geopolitical risks have an asymmetric and heterogenous impact on climate change stocks. The results provide significant insights and implications for financial market participants and policy makers.
本文旨在探讨在不同市场条件下,地缘政治风险(GPR)、威胁(GPT)和行为(GPA)对区域气候变化股票收益和波动性的影响,采用分位数回归方法。我们的主要结果表明,在牛市和熊市状态下,气候变化股票收益对 GPR 呈正向(负向)响应,但这种影响在不同地区并不一致。波动性主要对地缘政治紧张局势呈正向响应;地缘政治行为对波动性的影响似乎比地缘政治威胁更为显著。我们还发现,在俄乌战争期间,GPR 导致波动性上升,增加了不确定性。总体而言,研究结果表明,地缘政治风险对气候变化股票产生了非对称和异质的影响。研究结果为金融市场参与者和政策制定者提供了重要的见解和启示。
