Abstract This paper contributes to the literature on fiscal multipliers by estimating the effects of changes in revenue and in five groups of expenditures: public investment, social benefits, subsidies, personnel expenses, and other expenditures. We find that the strongest effects arise from shocks on public investments and social benefits, with both having a positive correlation with the sign of the shock. Increases in revenues, on the other hand, have statistically significant negative effects only in the short-run. The paper estimates the effects on GDP, primary balance, and public indebtedness of different fiscal consolidation scenarios. Results indicate that it is possible to combine reductions in the public indebtedness-to-GDP ratio with increases in GDP with a rebalancing of fiscal policy towards public investment and social spending and away from subsidies.
