This paper examines whether methodological deficiencies in the literature on discrimination in small business credit markets have a significant impact on the estimation of discrimination and provides a preliminary investigation into the causes of discrimination in these markets. The authors find substantial, statistically significant evidence of discrimination in loan approval against black-owned and Hispanic-owned businesses in 1998 with additional control variables, with a variety of different specifications, and with a simultaneous model of the application and loan-denial decisions.
