تثبیت قوانین تیلور زمانی که شوک عرضه دارای یک ریشه واحد است

This paper studies the implication of unit root supply shocks for the Taylor rule. I find that, when supply shocks have a unit root, if a central bank wishes to guarantee the stationarity of inflation, then their interest rate reaction function should not respond to the output gap. Once the stationarity of inflation is guaranteed by the output-gap-response parameter, the “Taylor principle” can be applied for warranting determinacy of the dynamics.
