Abstract
This study examines the impact of the COVID-19 pandemic on the time-varying systematic risk (beta) of 20 international airlines. Utilizing daily data from 2014 to 2023, time-varying betas are estimated through the BEKK-GARCH framework. To assess the asymmetric influence of the pandemic on airline be...
