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...

We use a regime-switching model to examine how exchange rate volatilities influence the failure of uncovered interest parity (UIP). Main findings are as follows. First, exchange rate returns are significantly influenced by regime switches in the relationship between the returns and interest rate...
