NEW YORK – Most observers regard unconventional monetary policies such as quantitative easing (QE) as necessary to jump-start growth in today’s anemic economies. But questions about the effectiveness and risks of QE have begun to multiply as well. In particular, ten potential costs associated with such policies merit attention.
First, while a purely “Austrian” response (that is, austerity) to bursting asset and credit bubbles may lead to a depression, QE policies that postpone the necessary private- and public-sector deleveraging for too long may create an army of zombies: zombie financial institutions, zombie households and firms, and, in the end, zombie governments. So, somewhere between the Austrian and Keynesian extremes, QE needs to be phased out over time.
