In order to investigate whether such impulse responses change over the course of the business cycle or over time, this paper uses TVP-VARs for US and Canadian data. For the US, we find interesting differences between the most recent recession and earlier recessions and expansions. In particular, we find the immediate effect of a negative shock on both infl‡ow and outfl‡ow hazards to be larger in 2008 than in earlier times. Furthermore, the effect of this shock takes longer to decay. For Canada, we find less evidence of time-variation in impulse responses.
