At this point, there is very little difference between aversion to inflation in countries that target and countries that do not target inflation. Taken together, the basic data, the time series tests, and the cross-section tests indicate that inflation targeting has seemed to succeed.
Inflation has dropped materially in the three countries with the longest experience with the regime, and all inflation targeting countries are still content with inflation targeting, in some cases eight to ten years after its adoption. Measures of inflation persistence also have dropped.
