The New Open Economy Macroeconomics has allowed economists to tackle classical problems with new tools, while also generating new ideas and questions. In their attempts to make the new models capture empirical regularities, researchers have entertained a variety of assumptions about the...

The exchange-rate regime is often seen as constrained by the monetary policy trilemma, which imposes a stark trade-off among exchange stability, monetary independence, and capital market openness. Yet the trilemma has not gone without challenge. Some (e.g., Calvo and Reinhart 2001, 2002) argue...

It is well known that if international linkages are relatively small, the potential gains to international monetary policy coordination are typically quite limited. What if, however, goods and financial markets are tightly linked? Is it then problematic if countries unilaterally design their...

We show that the when one takes into account the global equilibrium ramifications of an unwinding of the US current account deficit, currently running at more than 6% of GDP, the potential collapse of the dollar becomes considerably larger than our previous estimates (Obstfeld and Rogoff 2000a)...

The interwar period was marked by the end of the classical gold standard regime and new levels of macroeconomic disorder in the world economy. The interwar disorder often is linked to policies inconsistent with the constraint of the open-economy trilemmathe inability of policymakers...

This lecture presents a broad overview of postwar analytical thinking on international macroeconomics, culminating in a more detailed discussion of very recent progress. Along the way, it reviews important empirical evidence that has inspired alternative modeling approaches, as well as...

The discomfort a government suffers from speculation against its currency determines the strategic incentives of speculators and the scope for multiple currency-market equilibria. After describing an illustrative model in which high unemployment may cause an exchange rate crisis with...
