In a seminal contribution, Romer and Romer (2010) introduce a new dataset of exogenous tax changes and estimate a tax multiplier at 3 years of about -3. These results have been criticized as implausibly large. In this paper, I argue that on theoretical grounds the discretionary component of...

How much additional tax revenue can the government generate by increasing labor income taxes? In this paper we provide a quantitative answer to this question, and study the importance of the progressivity of the tax schedule for the ability of the government to generate tax revenues. We develop...

The 2008 financial crisis is the worst economic crisis since the Great Depression of 1929. It has been characterised by a housing bubble in a context of rapid credit expansion, high risk-taking and exacerbated financial leverage, leading to deleveraging and credit crunch when the bubble burst....

This Paper computes welfare-maximizing monetary and tax policy feedback rules, in a calibrated dynamic general equilibrium model with sticky prices. The government makes exogenous final good purchases, levies a proportional income tax, and issues nominal one-period bonds. A quadratic...

We examine the cross-country dispersion in fiscal outcomes during 2007-2009. In principle, international differences in fiscal policy may be related to differences in optimal fiscal positions, funding constraints, political economy factors and fiscal control problems. We find that the decline in...

Observed fiscal policy varies greatly across time and countries. How can we explain this variation? This paper surveys the recent literature that has tried to answer this question. We adopt a unified approach in portraying public policy as the equilibrium outcome of an explicitly specified...

We analyse different forms of international debt mutualisation in a simple framework with a political distortion and (partial) default under adverse economic circumstances. One form is a debt repayment guarantee, which can be "unlimited" or "limited", i.e. only be invoked when the guarantee...

Cross-country evidence on inflation and inequality suggests that they are positively correlated. I explore the hypothesis that this correlation is the outcome of a distributional conflict underlying the determination of fiscal policy.
