The impact of firm size on bank debt use

I use a sample of US firms to examine the determinants of the concentration of bank debt in total debt. The results indicate that the factors vary by size of the firm. A small- to medium-sized firm has a high concentration of bank debt when it has a low level of discretionary spending. In contrast, a large firm has a high concentration of bank debt when it is difficult for outsiders to observe. The results support the Diamond [J Polit Econ 99 (1991) 689] reputation view that a firm faces different debt choices as it grows. When evaluating bank regulations, policymakers should consider the importance of the reputation-building services, which a bank provides to businesses.
