The case of the undying debt
The French government currently honors a very unusual debt contract: an annuity that was issued in 1738 and currently yields ?1.20 per year. I tell the story of this unique debt, which serves as an anecdotal but symbolic summary of French public finances since the 18th century.

What’s a penny (or a nickel) really worth?
On December 14, 2006, the United States Mint announced new regulations to limit the melting and exportation of pennies and nickels. The goal is to prevent a shortage of small change in circulation. This article looks at the problem in historical context and suggests solutions.

The evolution of small change
Western Europe was plagued with currency shortages from the 14th to the 19th century, at which time a `standard formula' had been devised to cure the problem. We document the evolution of mon- etary theory, policy experiments and minting tech- nology over the course of six hundred years. In a companion paper, we use a cash-in-advance model of commodity money to provide an analytical frame- work for the problem of small change.

The debasement puzzle: an essay on medieval monetary policy
This paper establishes the stylized fact that medieval debasements were accompanied by unusually large minting volumes and revenues. This fact is a puzzle under the commonly held view that metallic coins are commodity money and exchange by weight. An existing explanation is that debased coins were used to reduce the real burden of nominally denominated debts. This explanation is logically flawed: nothing prevents agents from renegotiating contracts and avoid incurring minting costs. The paper also establishes other facts about monetary mutations, which altogether pose a challenge to monetary ...

Money, Banking, and Old-School Historical Economics
We review developments in the history of money, banking, and financial intermediation over the last twenty years. We focus on studies of financial development, including the role of regulation and the history of central banking. We also review the literature of banking and financial crises. This area has been largely unaffected by the so-called new econometric methods that seek to prove causality in reduced form settings. We discuss why historical macroeconomics is less amenable to such methods, discuss the underlying concepts of causality, and emphasize that models remain the backbone of our ...

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 model of bimetallism
Bimetallism has been the subject of considerable debate: Was it a viable monetary system? Was it a desirable system? In our model, the (exogenous and stochastic) amount of each metal can be split between monetary uses to satisfy a cash-in-advance constraint, and nonmonetary uses in which the stock of uncoined metal yields utility. The ratio of the monies in the cash-in-advance constraint is endogenous. Bimetallism is feasible: we find a continuum of steady states (in the certainty case) indexed by the constant exchange rate of the monies; we also prove existence for a range of fixed exchange ...

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.
