Working Paper: Fiscal tools at the zero lower bound
The paper analyses the effectiveness of fiscal tools at the zero lower bound (ZLB) in a non-linear New Keynesian DSGE model. Although the government spending multiplier increases at the ZLB, its size depends strongly on rational expectations to the liquidity trap length. In light of this finding, market expectations in the beginning of 2009 might indicate that expectations to the American Recovery and Reinvestment Act were too optimistic.
