Inflation targeting is currently popular with central banks. Is this popularity justified? I investigate this question by comparing a speed limit policy and inflation targeting with a Lucas-type Phillips curve capturing output gap persistence. If the output gap is at least moderately persistent, a speed limit policy can: (1) partly eliminate the state-contingent inflation bias, and (2) reduce inflation variability at no output gap variability cost.
