The proposed method offers a way of avoiding the assumption that the central bank can count on private-sector expectations coinciding precisely with whatever it plans to do, while at the same time also avoiding the equally unpalatable assumption that the central bank can precisely model private-sector learning and optimize in reliance upon a precise law of motion for expectations. The main qualitative conclusions of the rational-expectations analysis of optimal policy carry over to the weaker assumption of near-rational expectations. It is found that commitment continues to be important for optimal policy, that the optimal long-run inflation target is unaffected by the degree of potential distortion of beliefs, and that optimal policy is even more history-dependent than if rational expectations are assumed.
