During much of the last decade, U.S. fiscal policy has been procyclical, that is, destabilizing. We wasted the opportunity of the 2003-07 expansion by running large budget deficits. As a result, in 2010, Washington now feels constrained by inherited debts to withdraw fiscal stimulus at a time when unemployment is still high. Fiscal policy in the UK and other European countries has been even more destabilizing over the last decade. Governments decide to expand when the economy is strong and then contract when it is weak, thereby exacerbating the business cycle.
