Knife-edge stability is a common property of dynamic monetary models assuming perfect foresight or rational expectations. These models can be closed with the assumption that the economy's equilibrium lies on the unique convergent path (the saddlepath). While this empirically plausible assumption...

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 US current account deficit has been persistently large and has brought the country's ratio of foreign debt to GDP to 20%, a figure that is high by historical standards. This paper argues that while US solvency is not a near-term constraint on ongoing deficits, the sheer size of the US...

We develop an analytically tractable two-country model that marries a full account of global macroeconomic dynamics to a supply framework based on monopolistic competition and sticky nominal prices. The model offers simple and intuitive predictions about exchange rates and current accounts that...

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 nearly 6% of GDP, the potential collapse of the dollar becomes considerably larger (more than 50% larger) than our previous estimates...
