The Determinants of Bank Rates in Local Consumer Lending Markets: Comparing Market and Institution‐Level Results

Abstract

Most previous studies of banking markets have given little attention to the potential competitive discipline provided by credit unions on consumer loan rates. After presenting a theoretical framework for understanding the impact credit unions should be expected to have, this article analyzes two pooled cross‐section time‐series samples—56 U.S. markets over the 1992‐1998 period and 81 banks (within those markets) over the same period—with the focus on explaining bank rates for two types of consumer loans. Results confirm the previously observed role of market structure and strongly point to a significant role for credit unions in disciplining the exercise of market power by banks. At the institution level, where the impact of bank size, market share, and holding company status can be analyzed, the evidence supports both market power and scale economy rationales for bank loan pricing and hints at a multimarket contact influence.
