Bimetallism disappeared as a monetary regime in the 1870s. Flandreau (1996) clearly demonstrates that French bimetallism would have been able to withstand the German de-monetization of silver. Could it have withstood if many other countries in the world moved to the gold standard following in...

Previous studies of entry under New York's free banking law of 1838 have generated conflicting results. This article shows that different measures of entry lead to different conclusions about the competitive effects of the law. Measured by the entry of new banks, New York's free banking law led...

We propose a simple model of the international monetary system. We study the world supply and demand for reserve assets denominated in different currencies under a variety of scenarios: a Hegemon vs. a multipolar world; abundant vs. scarce reserve assets; a gold exchange standard vs. a floating...

Can competition among privately issued fiat currencies such as Bitcoin or Ethereum work? Only sometimes. To show this, we build a model of competition among privately issued fiat currencies. We modify the current workhorse of monetary economics, the Lagos-Wright environment, by including...

The paper explores optimizing models of small open economies that hold foreign money balances. Particular attention is paid to the impact of foreign inflation on the real exchange rate and other real variables. At first, an environment in which foreign money is the only traded asset is explored....

This paper is concerned with the reasons why some currencies, such as the pound sterling and the U.S. dollar, have come to serve as "vehicles" for exchanges of other currencies. It develops a three-country model of payments equilibrium with transaction costs, and shows how one currency can...

The literature has not being able to identify clear-cut real effects of exchange-rate regimes on output growth. Similarly, no definitive view emerges from the literature in regard to the effects of open capital markets on macroeconomic performance. The paper attributes the failure of the...

Exchange rate policies depend on portfolio choices, and portfolio choices depend on anticipated exchange rate policies. This opens the door to multiple equilibria in policy regimes. We construct a model in which agents optimally choose to denominate their assets and liabilities either in...

This paper discusses major analytical aspects of dollarization and their practical implications. We develop a simple model to stress that dollarization implies the loss of independent monetary policy and of seigniorage, yet the significance of such losses can only be evaluated in conjunction...

What is the optimal number of currencies in the world? Common currencies affect trading costs and, thereby, the amounts of trade, output, and consumption. From the perspective of monetary policy, the adoption of another country's currency trades off the benefits of commitment to price stability...
