In a monetary union, the interaction between several governments and a single central bank is plagued by several sources of deficit bias, including common pool problems. Each government has strong preferences over local spending and taxation but suffers only part of the costs of union-wide...

We extend the literature on local income tax competition by allowing for inter-jurisdictional spillovers and imperfect rivalry in consumption of a publicly provided good. Comparing decentralized second-best results of a theoretical model with an efficient benchmark, we identify three...

In fiscal interaction, a policy is evolutionarily stable if, once adopted by all governments, jurisdictions that deviate from it fare worse than those that stick to it. Evolutionary stability is the appropriate solution concept for models of imitative learning (policy mimicking). We show that...

In the wake of the euro area crisis, the debate on instruments to deepen economic integration among its members has intensified, among others putting forward a fiscal stabilization capacity for EMU members. Contributions made so far to further this idea have mostly concentrated on the...

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...

Does regional decentralization threaten the commitment to regional equality in government outcomes? We attempt to shed light on this question by drawing on unique evidence from the largest European unitary states to have engaged in countrywide health system decentralization: Italy and Spain. We...

This paper develops a theoretical explanation why it may be optimal for higher-level governments to pay categorical block grants or closed-ended matching grants to local governments. We consider a federation with two types of local governments which differ in the cost of providing public goods....

This paper examines capital tax competition in the presence of an interstate transfer policy without federal commitment. Lack of commitment implies that tax policy is chosen prior to federal transfers. The paper s main result is that ex-post federal policy internalizes horizontal fiscal...
