An international tax haven is usually a low-tax jurisdiction that seeks to attract investment by foreign investors. But, there are many state and local jurisdictions within federal systems that set zero tax rates on personal or corporate income, consumption, property, and wealth in an effort to...

If online transactions are tax-free, increased online shopping may lower tax rates as jurisdictions seek to reduce tax avoidance; but, if online firms remit taxes, online sales may put upward pressure on tax rates because the internet enforces destination-based taxes.

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...

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...
