The purpose of this paper is to analyse whether fiscal policies can alleviate the effects of the zero lower bound (ZLB) on interest rates and if they should be coordinated internationally. The analysis is carried out using EAGLE, a DSGE model of the global economy. We consider that the fiscal shocks are temporary and that fscal policy retains full credibility at all times. In this setup we find significant non-linearities in a ZLB situation that amplify theeffects of fiscal shocks compared to the non-ZLB case. International coordination is helpful but does not play a major role in the results.
