N. 839 - Gli effetti di shock fiscali incorporando le reazioni delle variabili di bilancio al debito pubblico in Italia

We study the effects of fiscal policy on macroeconomic developments in Italy over the period 1982-2010 with a Structural Vector Autoregression (SVAR) model. We include public debt and impose the government budget constraint in the estimation. In contrast with previous research we also include foreign demand, significantly improving estimation accuracy. We find that movements in debt induce stabilizing reactions in fiscal policy. In this context, expenditure and revenue shocks have significant effects on economic activity; these are stronger, as well as more precisely estimated and robust, for expenditure. Expenditure multipliers are higher when we exclude from our sample the initial years and, in particular, when we focus on the post-Maastricht period.
