Structural change, typically induced by policy regime shifts, is a common feature of dynamic economic models. We show that structural change can be used constructively to improve the identification of structural parameters that are stable over time. A leading example is models that are immune to...

Limited-information identification-robust methods on the indexation and price rigidity parameters of the new Keynesian Phillips curve yield very wide confidence intervals. Full-information methods impose more restrictions on the reduced-form dynamics, and thus make more efficient use of the...
