This chapter investigates whether the institutional environment that the firms operate has an impact on their leverage choice. Namely, rule of law is used as an institutional variable. Considering that better implementation of rule of law impacts positively firms' export performance, total exports in each country are also used as the other main explanatory variable. The findings show that both institutional variables and exports negatively and significantly affect the leverage level. This implies that firms in favorable institutional environment tend to borrow less, which results with lower leverage. Moreover, this study finds that the COVID-19 pandemic period as an unprecedented shock to economies pushed the leverage levels higher. Regarding the implications of the findings, firms' capacity to access external finance especially during a significant crisis period depends on the institutional environment. Namely, the effective implementation of rule of law should be first priority for the policy makers.
