When private agents learn a new policy rule, an optimal simple Taylor rule for disinflation differs substantially from that under full information. The central bank can reduce target inflation without much difficulty, but adjusting reaction coefficients on lagged inflation and output is more costly. Temporarily explosive dynamics emerge when there is substantial disagreement between perceived and actual feedback parameters, making the transition highly volatile. The bank copes by choosing reaction coefficients close to the private sector׳s prior mode, thereby sacrificing long-term performance in exchange for achieving lower transitional volatility.
