We document a decline in the dollar share of international reserves since the turn of the century. This decline reflects active portfolio diversification by central bank reserve managers; it is not a byproduct of changes in exchange rates and interest rates, of reserve accumulation by a small...

We present new evidence on the currency composition of foreign exchange reserves in the 1920s and 1930s. Contrary to the presumption that the pound sterling continued to dominate the U.S. dollar in central bank reserves until after World War II, we show that the dollar first overtook sterling in...

Alexander Swoboda is one of the originators of the bipolar view that capital mobility creates pressure for countries to abandon intermediate exchange rate arrangements in favor of greater flexibility and harder pegs. This paper takes another look at the evidence for this hypothesis using two...

This paper provides an historical perspective on reserve currency competition and on the prospects of the dollar as an international currency. It questions the conventional wisdom that competition for reserve-currency status is a winner-take-all game, showing that several currencies have often...

An influential school of thought views the current international monetary and financial system as Bretton Woods reborn. Today, like 40 years ago, the international system is composed of a core, which has the exorbitant privilege of issuing the currency used as international reserves, and a...

We use time-series methods to estimate a simple aggregate-supply aggregate-demand model in order to analyze the comparative performance of fixed- and flexible-exchange-rate systems and test competing hypotheses designed to explain shifts between exchange-rate regimes. The paper provides a...

This paper reports evidence on the characteristics of fixed and flexible exchange rate regimes. It contrasts experience under three interwar exchange rate regimes: the free float of the early 1920s, the fixed rates of 1927-31, and the managed float of the early 1930s. A number of important...
