Local sales tax rates influence the location of retail activity. This paper develops a theory and empirical identification strategy for studying sales tax competition with “multiple federations,” as exemplified by multiple counties each containing several cities. In addition to strategic...

By extending the standard model of commodity tax competition (Kanbur and Keen 1993) to include urban spatial structure (agglomeration) and online commerce, one can better analyze strategic tax-policy interactions among neighboring localities. Consumers buy different types of commodities, sold...

This paper analyzes the effect of wealth taxation on mobility and the consequences for tax revenue and wealth inequality. We exploit the unique decentralization of the Spanish wealth tax system in 2011—after which all regions levied positive tax rates except for Madrid—using linked...

This paper analyzes the effect of decentralized wealth taxation on mobility and the consequences for tax revenue and wealth inequality. Using linked administrative data, we exploit the decentralization of the Spanish wealth tax -- after which all regions except Madrid levied positive tax rates....

"Lines" in the tax system are demarcations of goods into different tax rate categories; tax rates may change discontinuously at a line. Geographic borders are a specific example of a line in the tax system. Using the example of geographic borders, I demonstrate how the permeability of the line...

We examine the effects of differences in income tax rates on commuting times within multi-state MSAs. Our theoretical model introduces a border into a model of an urban area and shows that differences in average tax rates distort commute times and interstate commutes. Empirically examining...

The standard partial equilibrium formula for pass-through substantially mismeasures incidence in the presence of demand or supply interdependencies. We study general equilibrium tax incidence in a perfectly competitive, multiproduct setting. If only one product is taxed, the general equilibrium...
