Money and debt in the structure of payments

Abstract

In Scott Freeman’s (1996) model, payment system arrangements based on intermediated debt that is settled with money achieve higher welfare than does direct money payment. In a simplified version of Freeman’s model, welfare can be further improved and efficiency achieved by a monetary authority participating in a secondary market for debt or by a private intermediary using a common clearinghouse device. The analysis clarifies that ordinary private agents can assume the role of central bank or clearinghouse; no artificial agent, posited solely to play that role and endowed with special capabilities for it, is necessary. The institutional features required for a central bank or a clearinghouse to achieve efficiency, particularly features related to central bank independence, are discussed informally.Payment systems
