This paper considers the general equilibrium relationship between exchange rates and global imbalances. It emphasizes that the exchange rate is not a primitive but an equilibrium price determined by the policy mix. It uses extensions of the two-country Obstfeld-Rogoff model to analyze the...

This paper investigates contagion effects. In a model with highly and lowly informed investors we show that a currency crisis in one country can trigger a crisis in another country. Portfolio losses of the highly informed investors in one country will force them to withdraw capital from the...
