This dissertation focuses on describing and explaining business cycle dynamics. Motivated by the extraordinary strong economic downturn in 2008/2009, it emphasis the importance of modeling nonlinearities. This thesis should be regarded as a contribution to applied econometrics and can be...

This paper estimates the interaction between monetary- and fiscal policy using a structural VAR model with time-varying parameters. For demand and supply shocks, the two policies are estimated to be complementary, while for monetary and fiscal policies shocks the two policies act as substitutes....

I introduce a factor structure on the parameters of a Bayesian TVP-VAR to reduce the dimension of the model's state space. To further limit the scope of over-fitting the estimation of the factor loadings uses a new generation of shrinkage priors. A Monte Carlo study illustrates the ability of...
