We examine several discrete-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. Failing to do so may result in switching...

We examine several discrete-time versions of the Cox, Ingersoll and Ross (CIR) model for the term structure, in which the short rate is subject to discrete shifts. Our empirical analysis suggests that careful consideration of which parameters of the short-term interest rate equation that are...
