Summers on Quantitative Easing
Larry is skeptical
There is also an oddity in this renewed emphasis on quantitative easing. The essential aim of such policies is to shorten the debt held by the public or issued by the consolidated public sector comprising both the government and central bank. Any rational chief financial officer in the private sector would see this as a moment to extend debt maturities and lock in low rates – exactly the opposite of what central banks are doing. In the U.S. Treasury, for example, discussions of debt-management policy have had exactly this emphasis. But the Treasury does not alone control the maturity of debt when the central bank is active in all debt markets.
