Central banking in an age of digital currencies is a fast-developing topic in monetary economics. Algorithmic digital currencies such as bitcoin appear to be viable competitors to central bank fiat currency, and their presence in the marketplace may pressure central banks to pursue tighter...

The strong monetary policy actions undertaken by advanced economies' central banks have led to complaints of “currency wars” by some emerging market economies, and to widespread demands for more macroeconomic policy coordination. This paper revisits these issues. It concludes that, while...

We analyze a two-country economy with complete markets, featuring two national currencies as well as a global (crypto)currency. If the global currency is used in both countries, the national nominal interest rates must be equal and the exchange rate between the national currencies is a risk-...

This paper explores the consequences of extremely low real interest rates in a world with integrated but heterogenous capital markets and nominal rigidities. We establish four main results: (i) Liquidity traps spread to the rest of the world through the current account, which we illustrate with...

The "Federalist financial revolution" may have jump-started the U.S. economy into modern growth, but the Free Banking System (1837-1862) did not play a direct role in sustaining it. Despite lowering entry barriers and extending banking into developing regions, we find in county-level data that...

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...

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...

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...

It is generally very difficult to measure the effects of a currency depreciation on a country%u2019s balance sheet and financing costs given the endogenous properties of the exchange rate. History provides at least one natural experiment to test whether an exogenous exchange rate depreciation...

This paper investigates Rodrik’s political-economy trilemma: policy makers face a trade-off of choosing two out of three policy goals or governance styles, namely, (hyper-) globalization, national sovereignty, and democracy. We develop a set of indexes that measure the extent of attainment of...
