We examine several continuous-time term structure models in which the short rate is subject both to continuous changes and to discrete shifts. Several regime-switching term structure models are developed, with regime-dependence in various combinations of their drift and diffusion parameters. We...

We examine several continuous-time term-structure models, in which the short rate is subject to discrete shifts. Our empirical analysis suggests that inquiring which parameters of the short-term interest rate equation are allowed to switch is crucial, as failing to do so may result in switching...
