Cross-border spill-overs from fiscal stimulus in a monetary union

We analyse domestic and cross-border effects of fiscal policy in a two-region business cycle model of a monetary union. Without relying on debt consolidation via spending reversals along the lines of Corsetti, Meier and Mueller (2010) and Corsetti and Mueller (2014) we show that a fiscal expansion by the core economies of the euro area is associated with crowding in of both core and periphery consumption. Interestingly, cross-border spill-over effects are larger the larger the share of credit constrained households in the periphery.
