Uncertainty about the precise quantitative effect of policy is endemic in economics. In a classic paper, Brainard showed that in the face of multiplier uncertainty in a static model that optimal policy is relatively conservative. I extend this work to a dynamic model and show in general that gradual adjustment is optimal and in the most simple case derive the classic partial adjustment model as the optimal response to shocks.
