More on Baking Structure and Performance: The Evidence from Texas

Published online by Cambridge University Press:  19 October 2009

Extract

A substantial amount of scholarly effort in recent years has been devoted to the determination of the relationship between banking structure and performance. In general, the results of these studies indicate that banking structure affects both the price and quantity of banking services, but, for practical policy purposes, the impact of banking structure is quite small. Yet, the results of these studies have been inconclusive and contradictory to a substantial degree.

5 If such aggregation is included in a study of banking structure and performance and if appropriate variables are not included to account for the differences in these banks, an inherent bias may exist toward finding a relationship between banking structure and performance.

6 To evaluate the importance of bias introduced into the results by intercorrelation of the independent variables, a careful analysis of the correlation matrix was made. The amount of intercorrelation among the independent variables was, in general, quite small. The largest single correlation coefficient among any of the independent variables was between average bank size and the ratio of business to total loans (0.54 in 1966), while most single correlation coefficients were substantially lower.

7 Conceptually, an important determinant of loan rates would be some index of money market and capital market rates as a measure of the opportunity cost of loanable funds. However, these rates become parameters when attempting to explain variations in loan rates among banks in a single state.

8 Kaufman's equation explaining variations in loan rates among Iowa counties explained between 20.0 and 31.4 per cent of the total variation in bank rates for the 2 years, 1959 and 1960.

9 The failure of the loan composition variables to prove statistically significant is quite surprising, both for a priori reasons and since Taylor's study of banks in the Southeast finds them to be highly significant. (Taylor, “Average Interest Charges,” p. 795.) A comparison of the simple correlation coefficients between the composition variables for similar loan categories and the loan rate revealed only minor differences in the correlation coefficients determined by Taylor's study and ours. However, other than a bank-size variable, Taylor's regressions did not include arguments for either structural or demand factors. This suggests that his loan composition variables may have served to some extent as proxies for banking structure and/or demand for bank loans. It is particularly interesting to note that when the four loan mix variables in the present study are regressed by themselves against the effective loan rate, the ratio of consumer loans to total loans proves significant at the 0.05 level in both 1966 and 1967. The addition of average bank size to this reduced regression format does not change the result vis-a-vis the loan composition arguments, although average bank size becomes significant at the 0.05 level in 1966 and at the 0.01 level in 1967.

11 The relationship may be nonrecursive, however, reflecting the potential dependence of costs on the loan-deposit ratio.
