| Abstract: | This paper outlines a new technique, which makes optimal control in a stochastic minimum variance framework computationally feasible. The new approach is then used to evaluate gains to policy coordination in the context of a macroeconometric model for the G-3. More specifically, we consider policy responses to a temporary price shock in a single country and in multi-country cases. The results show that coordination brings about a striking improvement in the overall control of inflation and a reduction in output costs. |
