Two recent papers (Gonçalves and Carvalho, 2009; and Brito, 2010) hold contradictory views regarding the role of inflation targeting during periods of disinflation. The first paper claims that inflation targeting reduces sacrifice ratios — i.e., the ratio of output losses to the change in trend inflation — during disinflations; the second paper refutes this result. We show here that inflation targeting only matters if disinflations are slow. The credibility gains of a fast disinflation make inflation targeting irrelevant for reducing the output-inflation trade-off.
