As the G-7 Leaders gather in Ise-Shima, Japan, on May 26-27, the still fragile global economy is on their minds.  They would like a road map to address stagnant growth. Their approach should be to talk less about currency wars and more about fiscal policy.Fiscal policy vs. monetary policyUnder the conditions that have prevailed in most major countries over the last ten years, we have reason to think that fiscal policy is a more powerful tool for affecting the level of economic activity, as compared to monetary policy.

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.

     Two decades ago, many thought the lesson of the 1980s had been that Japan’s variant of capitalism was the best model, that other countries around the world should and would follow it.   The Japanese model quickly lost its luster in the 1990s.        One decade ago, many thought that the lesson of the 1990s had been that the US variant of capitalism was the best model, that other countries should and would follow.   The American model in turn lost its attractiveness in the decade of the 2000s.
