Written on the 50th anniversary of floating exchange rates, this paper deals with possible alternatives to a unipolar dollar-based system.

Many central banks whose exchange rate regimes are classified as flexible are reluctant to let the exchange rate fluctuate. This phenomenon is known as "fear of floating". We present a simple theory in which fear of floating emerges as an optimal policy outcome. The key feature of the model is...

We provide a liquidity-based theory for the dominant use of the US dollar as the unit of denomination in global debt contracts. Firms need to trade their revenue streams for the assets required to extinguish their debt obligations. When asset markets are illiquid, as modeled via endogenous...

The evolution of the IMS and IFS in the past several hundred years can be viewed through the lens of the Copernican heliocentric system developed over 500 years ago. We trace out the evolution across regimes of the IMS and IFS in terms of network representations of the Copernican system. We...

This paper considers policies of the industrialized countries, as they pertain to crises in emerging markets. These fall into three areas: (1) their own macroeconomic policies, which determine the global financial environment; (2) their role in responding to crises when they occur, particularly...

We review and analyze the monetary and financial policies of the Clinton administration with a focus on the strong dollar policy, the Mexican rescue, the response to the Asian crisis, and the debate over reform of the international financial architecture. While we consider the role of ideas,...

In our book, Global Capital Markets: Integration, Crisis, and Growth, we traced out the evolution of the international monetary system using the framework of the "international monetary trilemma": countries can enjoy at most two from the set {exchange-rate stability, open capital markets, and...
