It is laudable for policy makers to shun fiscal profligacy and aim for self-reliance on the part of the private sector. But every several decades, the private sector loses its self- control in a bubble and sustains heavy financial injuries when the bubble bursts. That forces the private sector to pay down debt in spite of zero interest rates, triggering a deflationary spiral. At such times and at such times only, the government must borrow and spend the private sector’s excess savings, not only because monetary policy is impotent at such times but also because the government cannot tell the private sector not to repair its balance sheet.
Although anyone can push for fiscal consolidation in the form of higher taxes and lower spending, whether such efforts actually succeed in reducing the budget deficit is another matter entirely. When the private sector is both willing and able to borrow money, fiscal consolidation efforts by the government will lead to a smaller deficit and higher growth as resources are released to the more efficient private sector. But when the financial health of the private sector is so impaired that it is forced to deleverage even with interest rates at zero, a premature withdrawal of fiscal stimulus will both increase the deficit and weaken the economy. Key differences between the textbook world and the world of balance sheet recessions are summarized in Exhibit 17.
With massive private sector deleveraging continuing in the U.S. and in many other countries in spite of historically low interest rates, this is no time to embark on fiscal consolidation. Such measures must wait until it is certain the private sector has finished deleveraging and is ready to borrow and spend the savings that would be left un-borrowed by the government under an austerity program.
