  • Abstract: This paper evaluates the performance of the optimal monetary policy rule in the New Keynesian model. First, we take Blanchard and Gali (2008) as a baseline model, and compare the welfare loss between a classical Taylor rule (1993) and an optimal monetary policy rule (Woodford(2003)). Second, instead of assuming rational expectation in the baseline model, we introduce a heuristic forecasting rule that capturing animal spirit into the model that replacing forward looking expectations. Agents are divided into optimistic and pessimistic forecasters, and they are free to choose a forecasting rule according to the forecasting performance. We demonstrate the performance of the classical Taylor rule varies wildly across different models, while the welfare loss induced by the optimal rule are very stable. In addition, we check the robustness of the optimal monetary policy rule given the parameters that control the degree of animal spirit presented in the modified model. We conclude that the welfare loss is also stable given parameter uncertainty.
