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...

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 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 compares how cash and in-kind transfers affect local prices. Both types of transfers increase the demand for normal goods, but only in-kind transfers also increase supply. Hence, in-kind transfers should lead to lower prices than cash transfers, which helps consumers at the expense of...

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...

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...

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...

The quality of the money stock declined during the banking crises of the early 1930s. Bank deposits did not serve as a secure short- term store of purchasing power for use in an emergency as well as they had previously, and during the periods of restricted deposits in late 1932 and early 1933,...

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...
