This paper is a user' guide to a set of Guss procedures developed at the Bank of Canada for estimating regime-switching models. The procedure can estimate relatively quickly a wide variety of switching models and so should prove useful to the applied researchers. Sample program listings are...

Our paper uses simulation methods to examine the size and power of regime-switching tests for bubbles. We find that even with several hundred observations, the tests show sometimes considerable size distortion. This distortion makes the tests conservative; they understate the significance of the...

This paper analyzes the quality of VAR-based procedures for estimating the response of the economy to a shock. We focus on two key issues. First, do VAR-based confidence intervals accurately reflect the actual degree of sampling uncertainty associated with impulse response functions? Second,...

We investigate what happens to hours worked after a positive shock to technology, using the aggregate technology series computed in Basu, Fernald and Kimball (1999). We conclude that hours worked rise after such a shock

We provide empirical evidence that a positive shock to technology drives per capita hours worked, consumption, investment, average productivity and output up. This evidence contrasts sharply with the results reported in a large and growing literature that argues, on the basis of aggregate data,...

This paper derives analytical gradients for a broad class of regime-switching models with Markovian state-transition probabilities. Such models are usually estimated by maximum likelihood methods, which require the derivatives of the likelihood function with respect to the parameter vector....
