An empirical assessment of the U.S. Phillips curve over time
Vlekke, Marente; Koopman, Siem Jan; Mellens, Martin C. - 2021
We assess the stability of the unemployment gap parameter using linear dynamic Phillips curve models for the United States. In this study, we allow the unemployment gap parameter to be time-varying such that we can monitor the importance of the Phillips curve over time. We consider different...
