There is a significant controversy among academics and policy-makers about whether policies matter for economic growth. Recently, Acemoglu et al. (2003) and Easterly (2004) have presented empirical evidence against the commonly held view that policies play an important role in the process of...

Should rational agents take into consideration government policy announcements? A skilled agent (an econometrician) could set up a model to combine the following two pieces of information in order to anticipate the future course of fiscal policy in real-time: (i) the ex-ante path of policy as...

Motivated the European debt crisis, we construct a tractable theory of sovereign debt and structural reforms under limited commitment. The government of a sovereign country which has fallen into a recession of an uncertain duration issues one-period debt and can renege on its obligations by...

Despite intense scrutiny estimates of the government spending multiplier remain highly uncertain with values ranging from 0.5 to 2. While a fiscal consolidation is generally assumed to have the same (mirror-image) effect as a fiscal expansion, we show that relaxing this assumption is crucial to...

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...

This paper estimates the dynamic effects of changes in taxes in the United States. We distinguish between the effects of changes in personal and corporate income taxes using a new narrative account of federal tax liability changes in these two tax components. We develop an estimator in which...

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...

We examine the impact of fiscal policy interventions in an environment where the short term nominal interest rate is at the zero bound. In the basic New Keynesian model in which the monetary authority operates a Taylor rule, globally multiple equilibria arise, some of which display all the...

We study the effects of government spending by using a structural, large dimensional, dynamic factor model. We find that the government spending shock is non-fundamental for the variables commonly used in the structural VAR literature, so that its impulse response functions cannot be...
