This study documents a positive relation between managerial ability and the use of short-term debt. This finding is robust to various specifications, including a difference-in-difference approach based on CEO turnovers. Able managers' preferences for short-term debt are amplified for firms with greater growth opportunities and are attenuated by firms' refinancing risk. Additional analyses shed light on the implications of high-ability managers' strategic use of short-term debt. Overall, the results presented in this study demonstrate that managers' innate ability plays a critical role in shaping corporate debt maturity structure.
