What Global Imbalances? Saving Behavior Investment Behavior Portfolio Behavior

Global Imbalances in Connection with the Current Financial Crisis Global imbalances had little to do with the crisis, which was mainly caused by lax financial regulation on the part of the United States. Global Imbalances were the prime cause for the economic crisis as they depressed interest rates which incentivized investors to make risky investments. Global imbalances and lax financial regulation in the United States worked in concert to create the current financial crisis.

Evidence and Visual Aids

There is a sustained increase in the dispersion of current account balances worldwide starting in 1996, with a brief downturn in

The nature of global imbalances imbalances has changed through time. For instance, Japan was the main counterpart to U.S. deficits during the 1990s, and China took over this role with large surpluses in the early part of the 21 st century.

Savings Rate

Chinese Saving Statistics China –1981: 20% –1988: 30% –Present: remain at 40% GDP rate increased 10% yearly.

A Brief Summary Rising current account deficits in the United States particularly, with rising surpluses in China, the Middle East, and other Asian markets. Significant declines in household savings in the United States with an increase in household savings in developing countries.

An Argument for Positive Feedback Behavior Precipitating Crisis Rising U.S. deficits and surpluses in Asian countries and the Middle East spawned a savings glut in developing countries. Capital flowed to advanced countries. (primarily the U.S.) This caused interest rates to drop nearly worldwide. The drop in interest rates led to a boom in housing investment, and less household savings on average as U.S. investors moved to take advantage of the economic situation. Imbalances fed consumption which fed imbalances, and so a positive feedback loop was initiated.

How Imbalances Affect Crisis Imbalances in savings, investment, and portfolios led to a situation where real interest rates were driven down and assets increased in price. With easy sources of capital from surplus nations, and low interest rates, American households and investors were more willing to continue expanding consumption and the housing boom, as well as making riskier decisions in the instruments they used. All in all, imblances led to a unique combination of low interest rates, low inflation, housing appreciation, lax lending practices, credit expansion, and strong incentive towards high leverage. Eventually, interest rates in the United States had to adjust as the deficit moved to increasingly large amounts. As various investment instruments adjusted as well, investors found themselves looking at a decrease in asset prices and a simultaneous increase in the real interest rate.

What Can Be Done? The U.S. Government can reign in spending and lower the deficit, while the Chinese government brings its current account surplus into balance. Structural changes in Japan and Europe to break out of a low investment situation that relies on exports. Stimulation of Chinese domestic consumption.

Information Shocks and Macroeconomic Imbalance in the World Economy A discussion

3/25/10 1.Introduction 1.1Definition of the Imbalance of World Economy (1)Deficit or Surplus of BOP in a country (2)changes of Regional Economy (3)Waves of Global Economy For the time being, majority of economists and politician focus on the issue at a perspective of macroeconomic imbalance of one nation. That is to say, most of them define the imbalance of World Economy as (1).
