We study optimized monetary and fiscal feedback policy rules. The setup is a New Keynesian DSGE model of a closed economy which is solved numerically using common parameter values and fiscal data from the euro area. Our aim is to welfare rank alternative tax-spending policy instruments used for shock stabilization and debt consolidation when, at the same time, the monetary authorities can follow a Taylor rule for the nominal interest rate.

We build a new Keynesian DSGE model consisting of two heterogeneous countries participating in a monetary union. We study how public debt consolidation in a country with high debt (like Italy) affects welfare in a country with solid public finances (like Germany). Our results show that debt consolidation in the high-debt country benefits the country with solid public finances over all time horizons. By constrast, in Italy, namely the country that takes the consolidation measures, such a policy is productive only in the medium and long term. Thus, although there is a conflict of national interests in shorter horizons, there is a common interest in the medium and long term. All this is with optimized feedback policy rules. By contrast, debt consolidation is welfare inferior to non-consolidation for both countries and all the time, if it is implemented in an ad hoc way, like an increase in income taxes. Therefore, the policy mix is important. Terms of use: Documents inJEL-Codes: E600, F300, H600.

This paper quantifies the welfare differences among a monetary union, flexible exchange rates (economic disintegration) and a monetary plus fiscal transfer union (higher economic integration). The vehicle of analysis is a medium-scale New Keynesian DSGE model consisting of two heterogeneous countries. The model is solved using data from Germany and Italy. Our solutions imply that a switch to flexible exchange rates and independent monetary policies would have negligible welfare implications. A similar result applies when we add interregional fiscal tranfers as insurance. By contrast, the addition of fiscal tranfers as redistribution has nontrivial implications and these depend crucially on whether such one-sided transfers trigger moral hazard behavior or not.

We build a dynamic general equilibrium model with heterogeneous households, namely Rich and Poor, and capitalskill complementarity structure in the production function, to study aggregate and distributional implications of fiscal consolidation policies when the government uses a rich set of spending and tax instruments. Fiscal policy is conducted through constrained optimized fiscal rules. Our results show that, in the long run, fiscal consolidation enhances both aggregate efficiency and equity; however, it may hurt Rich households depending on which fiscal instrument takes advantage of the fiscal space created. Along the transition, wage inequality significantly increases due to the capital skill complementarity structure of the production function. Specifically, this happens because debt consolidation crowds in capital and this favours Rich (skilled) households. On the other hand, the reduction in interest rates and government bonds lead to a decrease in Rich households income coming from capital and government bonds which eventually decrease income inequality. Finally, a rather novel finding is that the combination of asset and skill heterogeneity amplifies the increase in wage inequality in the early phase of fiscal consolidation.
