“The upside of QE is limited. The money simply won’t go to where it’s needed, and the wealth effects are too small. The downside is a risk of global volatility, a currency war, and a global financial market that is increasingly fragmented and distorted. If the U.S. wins the battle of competitive devaluation, it may prove to be a pyrrhic victory, as our gains come at the expense of others—including those to whom we hope to export.”
