Regime Switching in VAR and DSGE Models: Theory and Applications


Regime switches are ubiquitous in economic data and can no longer be ignored in policy discussions. In a world with sometimes abrupt changes in uncertainty, breakdowns of economic structures and policy shifs (e.g unconventional policies), agents have to take into account the possibility of such events reoccurring.

This course will provide you with the necessary tools to analyse regime switches in economics.
