Asymmetric information and a theory of compensating balances

This paper derives an economic justification for the existence of compensating balance requirements using an equilibrium model of asymmetric information. Because bank profitability depends upon the probability distribution of a borrower's future cash requirements, and assuming this distribution is known by the borrower but not by the bank, compensating balance requirements can be used by the bank as a screen to distinguish among borrowers. Compensating balances are shown to exist without invoking assumptions of monopoly banks or non-maximizing behavior, and these balances need not be explained as a method of indirect payment for bank services.
