Many federal tax systems employ formula apportionment to allocate the taxable profits of large businesses to the federal subunits, where the subunits' specific tax rates are then applied. The formulas - such as the one recently proposed by the EU Commission and the one agreed upon by the...

There is ample evidence that internal capital markets incur efficiency costs for multinational enterprises (MNEs). This paper analyzes whether tax avoidance behavior interacts with the costs of running an internal capital market and how policies of competing governments respond to it. We show...

This paper explores the effects of tax provisions aimed at restricting multinationals' tax planning on foreign direct investment (FDI). Using a unique dataset which allows us to observe the worldwide activities of a large panel of multinational firms, we test how limitations of interest tax...

The increasing use of intellectual property as a means to shift profits to low-tax jurisdictions or jurisdictions with so-called "patent boxes" is a major challenge for the corporate tax base of medium- and high-tax countries. Extending a standard tax competition model for capital-enhancing...

This paper analyzes corporate tax-related policies and the difference between them in developed and developing countries. I show that the relationship between financial development and corporate income tax rates as well as the tax administrations' effectiveness follows a U-shaped pattern, a...

The Global Minimum Tax (GMT) is applied only to firms above a certain size threshold, permitting countries to set differential tax rates for small and large firms. We analyse tax competition between a tax haven and a non-haven country for heterogeneous multinationals to evaluate the effects of...

In 2009, the United Kingdom abolished the taxation of profits earned abroad and introduced a territorial tax system. Under the territorial system, firms have strong incentives to shift profits abroad. Using a difference-in-differences research design, we show that profits of UK subsidiaries in...

We study the choice between source-based and destination-based corporate taxes in a two-country model, allowing multinational firms to use transfer pricing to allocate profits across tax jurisdictions. We show that source-based taxation is a Nash equilibrium for tax revenue maximizing...

This paper analyzes tax competition when welfare maximizing jurisdictions levy source-based corporate taxes and multinational enterprises choose tax-efficient capital-to-debt ratios. Under separate accounting, multinationals shift debt from low-tax to high-tax countries. The Nash equilibrium of...

Almost 140 countries have agreed to reallocate the rights to tax international corporate profits and to introduce minimum tax rates. The agreed plan is the product of pragmatism and a search for consensus, but ambitious. It includes steps towards unitary taxation to be established by a...
