A note on reserve requirements and monetary control with a flexible deposit rate

This paper examines the relationship between reserve ratios and monetary control when deposit rates are flexible in the short run. For a total reserves operating target, it is shown that an increase in the deposit reserve ration may raise the variance of a monetary aggregate. Under an interest rate operating target, it is also shown that the deposit reserve ratio affects both the expected value and the variance of a monetary aggregate. These findings for the two alternative operating targets differ sharply from previous results which were based on the assumption of fixed deposit rates.
