We provide novel evidence that technological news and uncertainty shocks, identified one at a time using VAR models as in the literature, are correlated; that is, they are not truly structural. We then proceed by proposing an identification scheme to disentangle the effects of news and financial...

the variation in the GDP in Canada. My findings suggest that TFP news shock is the key driver of GDP in the medium run and … it creates significant positive co-movements among the aggregate variables at business cycle frequencies. Demand shock … dominates in the short run, however, its hard to pin down the exact source of the shock. The findings are robust to alternative …
