We study the link between a country's institutional quality in tax collection and its optimal corporate tax policies in a model of heterogeneous multinationals that can shift income using both debt and transfer prices. Countries with weak institutional quality can be made worse off adopting...

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 study develops theory and discusses implications of inflexibility in tax-motivated income shifting. We show that inflexibility to adjust income-shifting strategies within a tax year in response to losses implies that income-shifting incentives are based on the expected rather than the...

Many countries have introduced patent box regimes in recent years, offering a reduced tax rate to businesses for their IP-related income. Patent boxes are supposed to increase innovative activity, but they are also suspected to aim at attracting inward profit shifting from multinational firms....

This paper studies how corporate tax hikes transmit across countries through multinationals’ internal networks of subsidiaries. We build a parsimonious multicountry model to underscore two opposing spillover effects: While tax competition between countries generates positive investment...

We study how harmonization of corporate tax systems affects the stability of international cartels. We show that tax base harmonization reinforces collusive agreements, while harmonization of corporate tax rates may destabilize or stabilize cartels. We also find that bilateral and full...

This paper presents a theory model that simultaneously accounts for the financing decisions and ownership structure in affiliates of multinational firms. We find that affiliates of multinationals have higher internal and overall debt ratios and lower rental rates of physical capital than...

Multinational companies can exploit the tax advantage of debt more aggressively than national companies by shifting debt from affiliates in low tax countries to affiliates in high tax countries. Previous papers have either omitted internal debt or external debt from the analysis. We are the...

We demonstrate that the choice of the transfer price and its effect on intra-firm trade and investment depends on the probability of detection and thus on the measure, on which tax authorities base their audit. A policy implication of the paper is that it should be preferable to condition audits...

This paper studies the market and welfare effects of two main tax reforms - the Corporate Business Income Tax (CBIT) and the Allowance for Corporate Equity tax (ACE). Using an imperfect-competition model for a small open economy, it is shown that the well-known neutrality property of ACE does...
