An indexed unit of account is a money analogue, used to express prices; the unit's" purchasing power is defined by an index. Indexed units of account are not true money in that" they are not used as a medium of exchange. The first successful indexed unit of account Unidad de Fomento (UF) has...

We present an infinite horizon model with capital in which fiat money and barter are two competing means of payment. Fiat money has value because barter is limited by the extent of a double coincidence of wants. The pattern of exchange generally involves both money and barter. We find that the...

This paper reports an empirical test of a price dispersion equation, using data on the U.S. after World War II. The equation, derived elsewhere from aversion of the partial information-localized market models, relates price dispersion to the magnitude of changes in the aggregate disturbances. In...

A price dispersion equation is tested with data from the German hyper-inflation. The equation is derived from a version of Lucas' (1973) and Barro's (1976) partial information-localized market models. In this extension, different excess demand elasticities across commodities imply a testable...

We formulate a generalization of the traditional medium-of-exchange function of money in contexts where there is imperfect competition in the intermediation of credit, settlement, or payment services used to conduct transactions. We find that the option to settle transactions directly with money...

Over time, there has been a tendency for political jurisdictions and residents to converge on a single currency. Monopoly over seigniorage is a source of political power and a valuable lifeline when sovereignty is threatened. Moreover a uniform currency, insofar as it is free of counterparty and...

It is difficult for private agents to produce money that circulates at par with no questions asked. We study two cases of privately-produced money: pre-Civil War U.S. private banknotes and modern stablecoins. Private monies are introduced when there are no better alternatives, but they initially...

This paper studies why the General Theory had so much impact on the economics profession through the 1960s, why that impact began to wane in the 1970s, and why many economic policymakers cling to many of the tenets of the General Theory. We discuss three key elements along these lines, including...

Treasury bills and other near-money assets provide owners with liquidity service benefits that are reflected in prices in the form of a liquidity premium. I relate time variation in this liquidity premium to changes in the opportunity cost of money: The liquidity service benefits of near-money...

We develop a theory that rationalizes the use of a dominant unit of account in an economy. Agents enter into non-contingent contracts with a variety of business partners. Trade unfolds sequentially in credit chains and is subject to random matching. By using a dominant unit of account, agents...
