Abstract
We study the effects of decentralized wealth taxation on mobility and the effectiveness
of tax coordination at mitigating tax competition. We exploit the reintroduction of the
Spanish wealth tax, after which all regions except Madrid levied positive tax rates. We
find the mobility responses to wealth taxes are within the range of prior estimates with
respect to income taxes. However, wealth tax mobility responses generate losses to
personal income tax revenues that are six times larger than the direct losses to wealth
taxes. Madrid could achieve higher total regional revenues by agreeing to a harmonized
positive tax rate.
