Outline
The “savings glut” hypothesis
“I will argue that over the past decade a combination of diverse forces has created a significant increase in the global supply of saving - a global saving glut - which helps to explain both the increase in the U.S. current account deficit and the relatively low level of long-term real interest rates in the world today.(…) the developing and emerging-market countries that brought their current accounts into surplus did so to reduce their foreign debts, stabilize their currencies, and reduce the risk of financial crisis(..) Because investment by businesses in equipment and structures has been relatively low in recent years (…) much of the recent capital inflow into the developed world has shown up in higher rates of home construction and in higher home prices. Higher home prices in turn have encouraged households to increase their consumption” Bernanke (2005)

The Conceptual Framework
Accounting Identity of Financial Balances

In 2008 the identity was roughly like this: 1.1% of GDP -6.0% of GDP = -4.9% of GDPThird quarter 2009 the identity was roughly like this: 7.9% of GDP –10.9% of GDP = -3.0% of GDP

Global Rebalancing is Necessary
Policies to correct imbalances
• Revaluation of the currencies of surplus countries will be effective in reducing both global and U.S. domestic imbalances
• Such revaluation will require concerted actions of Central banks, particularly in East Asia
• Energy policies can reduce the impact of oil price changes on the U.S. trade balance, and the U.S. oil trade deficit
If these fail then . . .
“Unpopular” Policies may become necessary
Under WTO rules (Article 12), external imbalances can be addressed through “protectionist-type” measures - non-selective import tariffs- import certificates (Buffet proposal)- import certificates (Levy Institute version)The more effective resolution can probably be achieved only via an international agreement that would change the international pattern of aggregate demand, combined with a change in relative prices. Together, these measures would ensure that trade is generally balanced at full employment.
