Interjurisdictional competition over mobile tax bases is an easily understood mechanism, but actual tax-base elasticities are difficult to estimate. Political pressure for reducing tax rates could therefore be based on erroneous estimates of the mobility of tax bases. We show that tax...

We propose a new strategy to identify the existence of interjurisdictional tax competition and to estimate its spatial reach. Our strategy rests on differences between desired tax levels, determined by culture-specific preferences, and equilibrium tax levels, determined by interjurisdictional...

We study taxation externalities in federations of benevolent governments. Where different hierarchical government levels tax the same base, one can observe two types of externalities: a horizontal externality, working among governments of the same level and leading to tax rates that are too low...

We study the impact of tax competition on equilibrium taxes and welfare, focusing on the jurisdictional fragmentation of federations. In a representative-agent model of fiscal federalism, fragmentation among jurisdictions with benevolent tax-setting authorities unambiguously reduces welfare. If,...

Most cities enjoy some autonomy over how they tax their residents, and that autonomy is typically exercised by multiple municipal governments within a given city. In this chapter, we document patterns of city-level taxation across countries, and we review the literature on a number of salient...

The identification of strategic interactions among local governments is typically plagued by endogeneity problems. This paper proposes a quasi-experimental strategy to identify independent personal income tax setting by Swiss municipalities making use of the multi-tier federal system. State...

We propose a difference-in-differences strategy to identify the existence of interjurisdictional tax competition, and to estimate its spatial reach. Our strategy rests on differences between desired tax levels, determined by culture-specific preferences, and equilibrium tax levels, determined by...

Fiscal federalism concerns the division of policy responsibilities among different levels of government. Many current economic and policy developments, such as globalization, environmental crises and rising inequality, may not appear to be favorable to fiscal federalism, yet countries are...
