Does inflation targeting really make a difference? Evaluating the treatment effect of inflation targeting in seven industrial countries

We evaluate the treatment effect of inflation targeting in seven industrial countries that adopted this policy in the 1990s. To address the self-selection problem of policy adoption, we make use of a variety of propensity score matching methods recently developed in the treatment effect literature. Our results show that inflation targeting has no significant effects on either inflation or inflation variability in these seven countries. Further evidence from long-term nominal interest rates and income velocity of money also supports the window-dressing view of inflation targeting.
