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....

We investigate the effects of fiscal policy surprises for US data, using vector autoregressions. We overcome the difficulties that changes in fiscal policy may manifest themselves in variables other than fiscal variables first and that fiscal variables may respond ‘automatically’ to business...

Does fiscal consolidation lead to social unrest? Using cross-country evidence for the period 1919 to 2008, we examine the extent to which societies become unstable after budget cuts. The results show a clear correlation between fiscal retrenchment and instability. We test if the relationship...

This paper analyses the spectacular fiscal adjustment currently occurring in Italy. In 1990, the Italian General Government showed the second largest primary deficit-to-GDP ratio in Europe; in 1997 it is expected to have the largest primary surplus-to-GDP ratio, with a 3% overall deficit-to-GDP...

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...

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...

Underdevelopment is thought to be about lack of investment, and many political economy theories can account for this. Yet, there has been much investment in developing countries. The problem has been that investment growth has not led to output growth. We therefore need to explain not simply...

What are the cyclical properties of US state and local government fiscal policy? The budget surplus of local and, in particular, state governments is procyclical, smoothing disposable income and consumption of state residents. This happens over both short- and medium-term horizons. Procyclical...

We develop a model of human capital formation with endogenous labour supply and heterogeneous agents to explore the optimal level of education subsidies along with the optimal progressive schedule of the labour income tax and optimal capital income taxes. Subsidies on education ensure efficiency...
