In this issue of the journal, Ibtissem Kaabi analyzes the effectiveness of the audit committee of the board of directors during the COVID-19 pandemic in French firms. Their findings are consistent with the higher activity of the board during this period being positively related to the effectiveness of the audit committee. In the second article of this issue, Ihsanul Ikhwan, Mohamed Asmy Mohd Thas Thaker, and Hassanudin Mohd Thas Thaker also focus their analysis on the COVID-19 pandemic, analyzing the technical efficiency of Indonesian government-owned banks. They detect the most efficient banks and the overall tendency of efficiency during this complicated period. It would be very relevant to understand how these issues are when firms belong to business groups.
