Research Discussion Paper – RDP 2008-10 Solving Linear Rational Expectations Models with Predictable Structural Changes


Standard solution methods for linear stochastic models with rational expectations presuppose a time-invariant structure as well as an environment in which shocks are unanticipated. Consequently, credible announcements that entail future changes of the structure cannot be handled by standard solution methods. This paper develops the solution for linear stochastic rational expectations models in the face of a finite sequence of anticipated structural changes. These events encompass anticipated changes to the structural parameters and anticipated additive shocks. We apply the solution technique to some examples of practical relevance to monetary policy.
