Endogenous financial innovation and the demand for money
This paper embeds two key ideas about the nature of financial innovation taken from the empirical literature into a familiar equilibrium monetary model. It provides formal support for several alternative econometric specifications for money demand that attempt to capture the effects of financial innovation and demonstrates that a popular theoretical model of money demand, when suitably modified, can account for some unusual monetary dynamics found in the data. Thus, it helps to establish both the theoretical relevance of recent empirical work and the empirical relevance of recent theoretical ...

Money and finance in a model of costly commitment
Journal Article
Acceptability, means of payment, and media of exchange
This essay explains the use of fiat money, or why intrinsically useless objects are accepted as payment in transactions. People accept a particular object as a means of payment because others do: social conventions matter more than the intrinsic characteristics of the object itself. Not everything can become a fiat money, though. If an object is especially costly to hold, for example, it will not be accepted as a means of payment. This explanation of fiat money is illustrated in a simple theoretical economic model. ; This essay was originally published in The New Palgrave Dictionary of Money ...

Money, inflation, and output under fiat and commodity standards
This study examines the behavior of money, inflation, and output under fiat and commodity standards to better understand how changes in monetary policy affect economic activity. Using long-term historical data for 15 countries, the study finds that the growth rates of various monetary aggregates are more highly correlated with inflation and with each other under fiat standards than under commodity standards. Money growth, inflation, and output growth are also higher under fiat standards. In contrast, the study does not find that money growth is more highly correlated with output growth under ...

A model of commodity money, with applications to Gresham's Law and the debasement puzzle
We develop a model of commodity money and use it to analyze the following two questions motivated by issues in monetary history: What are the conditions under which Gresham's Law holds? And, what are the mechanics of a debasement (lowering the metallic content of coins)? The model contains light and heavy coins, imperfect information, and prices determined via bilateral bargaining. There are equilibria with neither, both, or only one type of coin in circulation. When both circulate, coins may trade by weight or by tale. We discuss the extent to which Gresham's Law holds in the various cases. ...

A unified framework for monetary theory and policy analysis
Search-theoretic models of monetary exchange are based on explicit descriptions of the frictions that make money essential. However, tractable versions usually have strong assumptions that make them ill suited for discussing some policy questions, especially those concerning changes in the money supply. Hence, most policy analysis uses reduced-form models. The authors propose a framework, designed to help bridge this gap, that is based explicitly on microeconomic frictions, but allows for interesting macroeconomic policy analyses. At the same time, the model is analytically tractable and ...

The big problem of small change
Western Europe was plagued with currency shortages from the 14th century, at which a 'standard formula' had been devised to cure the problem. We use a cash-in-advance model of commodity money to define a currency shortage, show that they could develop and persist under commodity money regime, and analyze the role played by each ingredient in the standard formula. A companion paper documents the evolution of monetary theory, monetary experiments and minting technology over the course of six hundred years.
