The costs of disinflation are explored using the Board's new sticky-price rational expectations macroeconometric model of the U. S. economy, FRB/US. The model nests both model consistent and restricted-information rational' expectations. Monetary policy is governed by interest-rate reaction functions of which two are considered: the well-known Taylor rule and another rule that is more aggressive and richer in its specification, estimated using data for the last fifteen years. Agents are required to learn of shifts of the inflation target using linear updating rules. The simulated costs of disinflation are compared with other estimates of sacrifice ratios. | Finance And Economics Discussion Series by Antulio Bomfim, Paperback | Indigo Chapters
