In terms of implementation and provision of success of economic policies, it is an important issue that the resulting shocks in macro variables caused from a variety of reasons are temporary or permanent. The comprehension that increases policy makers’ credibility and also mediates the formation of expectations management on economic units causes a more stable economic process when this comprehension perceives the response rate given to the shocks in macro variables. This study searches the persistence of inflation for 11 EU countries and Turkey reaches the following evidence; for Germany, Italy and Portugal, an inflation existing after a shock converges fast to its own average value, the inflation series related to these countries is stationary and inflation persistence has remained at a low-level for these countries. When the Lucas criticism is considered, inflation returns to it’s own average level rapidly and the inflation persistence is in a low level for Germany, Austria, Finland, France, Netherland and Italy.
