I propose a model where agents choose to conduct their business using two payment instruments, money and bilateral credit. A friction in the timing of transactions rationalizes the use of both instruments and makes it optimal for agents to use money as a means of settlement for credit. Money and credit complement each other. With anticipated inflation, complementarity implies that the credit to money ratio decreases with inflation.
