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...

Private pension provision faces the challenging task of providing stable income streams during retirement. The challenge has increased markedly in the last decades due to volatile financial markets, falling interest rates and the withdrawal of employers and external insurers as risk bearers of...

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...

Inspired by the current debate over the future of the monetary union in Europe, this paper provides a simple model for the determination of the conditions of survival of the common good, which requires the creation of an effective fiscal union. We highlight the importance of institutional design...

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 develops a theory characterizing the effects of fiscal policy on unemployment over the business cycle. The theory is based on a model of equilibrium unemployment in which jobs are rationed in recessions. Fiscal policy in the form of government spending on public-sector jobs reduces...

This research revisits the cyclicality of fiscal policies. To identify and estimate more precisely the magnitude of a causal effect of cyclical income on government spending, we employ annual rainfall data as an instrument for national income in the context of sub-Saharan countries. Our results...

As governments around the world contemplate slashing budget deficits, the "expansionary fiscal consolidation hypothesis" is back in vogue. I argue that, as a statement about the short run, it should be taken with caution. Alesina and Perotti (1995) and Alesina and Ardagna (2010) (AAP) show that...
