Are commercial bank lending propensities useful in understanding small firm finance?

Abstract

We consider recent criticism by Berger et al. (J Bank Finance 31:11–33, 2007) of the use of commercial bank lending propensities (e.g., small business loans/total assets) as research tools. We use 2SLS cross sectional regressions with bank fixed effects to examine the relationship between small business lending and bank size. Our results indicate that the propensity to lend to small businesses declines as bank size increases, and the growth in small business lending does not keep pace with the growth in bank size. An increase in bank asset size from $1 billion to $100 billion reduces the ratio of small business loans to total loans and leases by 28 percentage points. Contrary to Berger and Black (2007) we find that most small business loans are made by small banks. For 1993 to 2006 as a whole, small banks (those under $1 billion) accounted for only 14.1% of total deposits and 9.7% of total banking assets, but they accounted for 28.4% of small business loans outstanding. This is consistent with the pattern shown by lending propensities. We conclude that these propensities remain very useful tools in research on small firm finance.
