This paper explores how economic uncertainty affects firms' climate change exposure. We use an extensive sample from 24 countries from 2002 to 2021. Employing a novel measure of firm-level climate change exposure developed by Sautner et al. (2023b), we empirically demonstrate that prior to the Paris Agreement in 2015, economic uncertainty leads to a decrease in climate change disclosures. However, after the Paris Agreement, our findings reveal a positive association between economic uncertainty and climate change exposure. The positive disclosure effect is primarily driven by higher climate-related opportunities and regulatory exposures. Our findings are robust when we employ alternative definitions for economic uncertainty, alternative samples, additional firm-level and country-level control variables, and alternative methodologies. We find that institutional and foreign ownership positively moderates the association between economic uncertainty and climate change exposure after the Paris Agreement. Further analysis investigates the moderating impact of country-level environmental performance indicators. We present novel empirical evidence suggesting that firms operating in countries with less climate vulnerability, higher readiness, more stringent environmental policies, superior climate protection performance, and higher environmental litigation risk tend to have higher climate change exposure in uncertain times.
本文探讨经济不确定性如何影响企业的气候变化风险敞口。我们使用了2002年至2021年来自24个国家的大量样本。采用Sautner等人(2023b)开发的一种新的企业层面气候变化风险敞口衡量方法,我们通过实证证明,在2015年《巴黎协定》之前,经济不确定性导致气候变化披露减少。然而,在《巴黎协定》之后,我们的研究结果显示经济不确定性与气候变化风险敞口之间存在正相关关系。积极的披露效应主要由更高的气候相关机遇和监管风险驱动。当我们采用经济不确定性的替代定义、替代样本、额外的企业层面和国家层面控制变量以及替代方法时,我们的研究结果依然稳健。我们发现,机构所有权和外资所有权在《巴黎协定》之后正向调节经济不确定性与气候变化风险敞口之间的关联。进一步的分析考察了国家层面环境绩效指标的调节作用。我们提供了新的实证证据,表明在气候脆弱性较低、准备程度较高、环境政策更严格、气候保护绩效更好以及环境诉讼风险较高的国家运营的企业,在不确定时期往往具有更高的气候变化风险敞口。
