We propose a model in which money performs an essential role in the process of exchange, despite the presence of a multilateral clearing house that collects resources from and distributes them to anonymous agents. Money improves the functioning of the clearing house, simultaneously keeping the incentives to contribute and guaranteeing the fine-tuning of allocations.
The paper was presented under the title “A quasi-Walrasian model of money” at several departmental seminars and conferences, including the 2013 Chicago Fed Summer Workshop on Money, Banking, Payments and Finance, and the IV Workshop on Institutions, Individual Behavior and Economic Outcomes, Alghero, Sardinia. We thank Randall Wright for suggesting the interpretation of limited enforcement as finite memory and seminar participants for comments.
