News, fiscal rules and the Keynesian multiplier in a DSGE model

Abstract

We extend the standard Smets-Wouters (2007) medium-sized DSGE model to analyse the effects of news and the Keynesian multiplier. News is modelled in a novel way compared to the literature, as revisions of expectations regarding future fundamentals. News-driven expectations changes augment both the consumption Euler equation and a fiscal rule, which is a secondary innovation of the paper. This news channel significantly improves the model fit to data. We calculate the fiscal multipliers which appear more Keynesian (with a higher effect on output and a positive effect on consumption, more persistent) than argued in much preceding literature.
