A Note on Concentration and Checking Account Prices
评估了银行研究中用代理变量代替实际支票账户价格的做法，比较了三种常用代理变量与154家德克萨斯银行实际价格。
ABSTRACT A recent survey ( Rhoades, 1977b ) of StructureConductPerformance studies in banking lists twelve studies of the effect of concentration on checkingaccount prices. All twelve rely on proxies for price instead of actual price. Here we evaluate this practice by comparing the three most widely used proxies with the prices actually charged by a sample of 154 Texas banks.
