It’s Not About Conspiracy Theorizing, It’s About Effectiveness

February 13, 2015

Yesterday Paul Krugman took some pot shots at an op-ed that Paul Ryan and I wrote nearly five years ago—an op-ed that was critical of quantitative easing. Here’s why Krugman missed his mark and the QE critics are correct.
