Does Credit Scoring Produce a Disparate Impact?
Abstract: The widespread use of credit scoring in the underwriting and pricing of mortgage and Consumer Credit has raised concerns that the use of these scores may unfairly disadvantage minority populations. A specific concern has been that the independent variables that comprise these models may have a disparate impact on these demographic groups. By "disparate impact" we mean that a variable's predictive power might arise not from its ability to predict future performance within any demographic group, but rather from acting as a surrogate for group membership.
