This article challenges the conventional wisdom that price level targeting necessarily increases the volatility of inflation and economic activity. It shows that the optimal policy under commitment for a society that cares only about the variability of output and inflation involves only a limited degree of base drift. The result crucially depends on the importance of forward-looking behaviour and on the credibility of the commitments. The case for price level targeting is strengthened when the possibility of a binding lower bound on nominal interest rates is considered. This may be increasingly relevant in a low inflation environment. This justifies renewed interest on price level targets in the context of thinking through how to prevent and respond to deflationary risks.
