As the COVID-19 pandemic has shaped public policies and government finances, it has also influenced the topics that public finance economists are researching. Because the 2020 International Institute of Public Finance (IIPF) Congress featured papers that were submitted prior to the start of the...

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....

Taxes and cash transfers reduce income inequality more in France than elsewhere in the OECD, because of the large size of the flows involved. But the system is complex overall. Its effectiveness could be enhanced in many ways, for example so as to achieve the same amount of redistribution at...

In this paper we investigate the interplay between national rainy-day funds and supra-national transfers in a fiscal union. Given that the EU has established rules limiting deficits, national rainy-day funds could in theory provide a way for countries to obey the rules and use fiscal policy, yet...

The "Decentralization Theorem" (Oates, 1972) is central to the discussion of fiscal federalism. We revisit the role of consumption spillovers in evaluating the merits of (de)centralization. Unlike the general prediction, a higher degree of spillovers may reduce the difference in utility of...

Fiscal rules are controversial. They mitigate politicians' flexibility in responding to shocks and pursuing expansionary fiscal policy. They help, however, to handle politicians' commitment problem in fiscal policies. I portray the new and fast growing empirical literature in public economics...

I develop a political economy theory of dynamic fiscal competition via public spending and debt. With internationally mobile capital, strategic policies generate two cross-border externalities that voters in each country fail to internalize: (1) an increase in public spending that bolsters...

This paper critically surveys the growing literature on the policy choices of local governments. First, we identify various reasons for local government policy interactions, including fiscal competition, bidding for firms, yardstick competition, expenditure spillovers, and Tiebout sorting. We...
