THE INFLUENCE OF THRIFT COMPETITION ON BANK BUSINESS LOAN RATES

This article assesses the competitive influence of thrift institutions on the pricing of commercial loans made by commercial banks. Using detailed survey information on the rates that individual banks charge for various types of commercial loans, we attempt to determine which of various proposed weightings of thrift institutions, when incorporated in measures of market concentration, best explains loan rates. After considering several weighting schemes, including those designed to approximate current regulatory practice in analyzing the competitive impact of proposed bank mergers, we find that in all but one of the cases examined, the use of a positive weight for thrift institutions explains bank loan rates, if anything, more poorly than does a weighting of zero for such institutions.
