Why, at the end of the 20th century, should capital markets have served to transfer resources from emerging markets to those which are more developed? Mr. Bernankes interpretationthat the global imbalances reflected a Savings Glut in the East fueled by fear of financial crisishas been challenged for neglecting dis-saving in the West. As we show, these contrasting perspectives can be combined in a stochastic two period, two bloc model: one bloc, the East, has a precautionary saving incentive due to future income uncertainty, while the other, the West, experiences a bubble and, because it smoothes consumption, runs a current account deficit. The tractable global model we use, which relaxes the conventional assumptions of a representative agent and unbiased expectations, shows how a significant resource transfer can be effected with relatively small changes in global interest rates.
