This article reviews arguments in the literature for and against price-level targeting, focusing on its costs and benefits compared with inflation targeting. Benefits of price-level targeting include the effect on forward-looking inflation expectations; the ability to substitute for commitment by a central bank to its future policies; lessening forecast errors; better economic performance in response to real shocks because of lower wage indexation; and a reduction in the problem of the zero lower bound on nominal interest rates.

Ambler describes three new channels through which inflation affects economic welfare in New Keynesian models. These channels were absent from traditional analyses and may have caused researchers to underestimate the costs associated with variable inflation, even at relatively low levels of inflation. The article concludes with a preliminary assessment of the quantitative importance of the new channels and their significance for monetary policy.
