Understanding how ESG-focused airlines reduce the impact of the COVID-19 pandemic on stock returns.

Incorporating environmental-social-governance (ESG) into a company's operations is an innovation strategy for contemporary businesses and a countermeasure for airline companies under COVID-19's influence. This research employs an autoregressive jump intensity trend (ARJI-trend) model to analyze the effects of COVID-19 and ESG ratings on the stock performance of the U.S. airline industry. We find that the ARJI-trend model captures the short- and long-run impacts of COVID-19 and ESG on stock return dynamics. Moreover, short-run stock return volatility converges to the original equilibrium level faster when a company has a higher ESG score, implying that promoting ESG does offer a defense mechanism to airline companies and that ESG performance is suitable for integration into business operational goals. The results lay the groundwork for understanding how an ESG focus might help airline companies to suffer less of an economic/financial impact during crises such as the COVID-19 pandemic.
