In this paper we show that when applying for small business loans in the U.S., Black, White and Hispanic owned businesses are treated differently from each other. In particular, the manner in which banks use other information about the firm (such as credit rating) differs across these groups. We argue that these differences are consistent with race based statistical discrimination.
We develop a simple theoretical model that shows that the effect of signals on loan approval rating can differ when banks believe there is an underlying difference in riskiness between two groups (all else equal). Some of the obvious signals are standard credentials such as the company financials. However, the banks may also be tempted to use other information such as the race of the owner. When the financials are average, the information about race can have a significant effect on the anticipated probability that the loan will be repaid. When the financials are tremendous (or abysmal), race should be less informative and should have very little effect on the anticipated probability of repayment. Companies that are statistically discriminated against based on race should see their approval rating increase more rapidly as their financials improve. That is for firms who have faced statistical discrimination and have good financials; an increase in the quality of the financials should have a greater effect on the bank’s anticipation of repayment than for firms that were already seen as better risks. Other types of discrimination, such as taste based discrimination, should not have this effect. We also test this theory using publicly available data from the Federal Reserve’s Survey of Small Business Finances (2003 and 1998), finding results that support our hypotheses.
