Recent crises in emerging markets have been heavily driven by balance-sheet or net-worth effects. Episodes in countries as far-flung as Indonesia and Argentina have shown that exchange rate adjustments that would normally help to restore balance can be destabilizing, even catastrophic, for countries whose debts are denominated in foreign currencies. Many economists instinctually assume that developing countries allow their foreign debts to be denominated in dollars, yen, or euros because they simply don't know better. Presenting evidence that even emerging markets with strong policies and institutions experience this problem, Other People's Money recognizes that the situation must be attributed to more than ignorance.
