This paper uses a New Keynesian framework to study the coordination of fiscal and monetary policies, in response to an inflation shock when the policymaker acts with commitment. We first show that, in the simplest New Keynesian model, fiscal policy plays no part in the optimal policy response,...

This paper studies a simple New-Keynesian model of fiscal and monetary policy coordination when the policymaker acts under commitment. With a New Keynesian Phillips curve it is optimal to control inflation only through the use of monetary policy. But, when price-setters use a Steinsson (2003)...

We use the time series of shifts in U.S. Federal tax liabilities constructed by Romer and Romer to estimate tax multipliers. Differently from the single-equation approach adopted by Romer and Romer, our estimation strategy (a Var that includes output, government spending and revenues, inflation...

We study the effects of changes in uncertainty about future fiscal policy on aggregate economic activity. Fiscal deficits and public debt have risen sharply in the wake of the financial crisis. While these developments make fiscal consolidation inevitable, there is considerable uncertainty about...

This paper shows how the richer frequency and variety of fiscal policy shocks available in an international sample can be analyzed recognizing the heterogeneity that exists across different countries. The main conclusion of our empirical analysis is that the question 'what is the fiscal policy...

The global recession of 2008-09 has revived interest in the international repercussions of domestic policy choices. This paper focuses on the case of fiscal stimulus, investigating cross-border spillovers from an increase in exhaustive government spending on the basis of a two-country business...

We examine debt-sensitive majority rules. According to such a rule, the higher a planned public debt, the higher the parliamentary majority required to approve it. In a two-period model we compare debt-sensitive majority rules with the simple majority rule when individuals differ regarding their...

The currently available empirical evidence shows remarkable differences between various estimates of the effects on U.S. output of an exogenous shift in Federal tax liabilities. Shocks identified via the narrative method imply a multiplier of about three over an horizon of three years. Tax...

The global financial crisis of 2008-09 has sent public debt on sharply higher trajectories. With the economic recovery gradually taking hold, the focus is now shifting to fiscal "exit" strategies. Medium-term consolidation efforts are likely to include not only tax increases but also sizeable...

We use a dynamic factor model to provide a semi-structural representation for 101 quarterly US macroeconomic series. We find that (i) the US economy is well described by a number of structural shocks between two and six. Focusing on the four-shock specification, we identify, using sign...
