The U.S. political-economic system gives evidence of a phenomenon known as “instrument instability.” Policy makers at the Federal Reserve and the White House are attempting to use highly imperfect monetary and fiscal policies to stabilize the national economy. The result, however, has been ever-more desperate swings in economic policies in the attempt to prevent recessions that cannot be fully eliminated.

President Barack Obama’s economic team is now calling for an unprecedented stimulus of large budget deficits and zero interest rates to counteract the recession. These policies may work in the short term but they threaten to produce still greater crises within a few years. Our recovery will be faster if short-term policies are put within a medium-term framework in which the budget credibly comes back to balance and interest rates come back to moderate sustainable levels.

We need to avoid reckless short-term swings in policy. Massive deficits and zero interest rates might temporarily perk up spending but at the risk of a collapsing currency, loss of confidence in the government and growing anxieties about the government’s ability to pay its debts. That outcome could frustrate rather than speed the recovery of private consumption and investment. Deficit spending in a recession makes sense, but the deficits should remain limited (less than 5 percent of GNP) and our interest rates should be kept far enough above zero to avoid wild future swings.

In short, although the sharp downturn will unavoidably last another year or even two, we will not need zero interest rates and mega-deficits to avoid a depression or even to bring about a recovery. In fact, the long-term, sustainable recovery will be accelerated by a policy framework in which the budget credibly returns to balance over several years, the government meets its critical responsibilities in social services, infrastructure and regulation, and the Fed avoids dangerous swings in interest rates that actually contribute to the booms and busts we seek to avoid
