model indexation regulates the sources of inflation persistence. When indexation is zero, the inflation gap is purely … forward- looking and inflation persistence depends only on the level of trend inflation, while full indexation makes the … inflation gap persistent and it eliminates the effects of trend inflation. We show that in the former case the optimal policy is …

In the Eurozone price stickiness differs among countries. I explore its consequences on the optimal rate of inflation … in a two-country model. On the one hand, with local currencies an inflation tax is partly imposed on the foreign country … optimal inflation is positive, ii) in a monetary union the first motive is absent and the optimal inflation is negative and …

If inflation expectations become firmly anchored at the inflation target even when average inflation deviates from the … target, the long-run Phillips curve becomes non-vertical.

The analysis is motivated by the disinflation performance of many inflation … episode price-setting firms' expect inflation to be highly persistent and opt for backward-looking indexation.

-run trade-offs between output and inflation: lower trend inflation flattens the Phillips curve and decreases steady-state output … by increasing markups. We show that the aggregator reduces both the steady-state welfare cost of higher trend inflation … and the inflation-related weight in a model-based welfare function for higher trend inflation. Consequently, optimal trend …
