We study the optimal combination of corporate tax rate and tax base in a model of a small open economy with heterogeneous firms. We show that it is optimal for the small country's government to effectively subsidize capital inputs by granting a tax allowance in excess of the true costs of...

This paper analyzes a model of corporate tax competition with repeated interaction and with strategic use of profit shifting within multinationals. We show that international tax coordination is more likely to prevail if the degree of asymmetry in terms of productivity differences between...

This paper estimates the size and macroeconomic effects of base erosion and profit shifting (BEPS) using a computable general equilibrium model designed for corporate taxation and multinationals. Our central estimate of the impact of BEPS on corporate tax losses for the EU amounts to €36...

This paper investigates the consequences of a series of alternative international tax designs on the strategy of a multinational enterprise regarding the cross border distribution of its investment and the choice of its financing behavior. We start with a world where no international tax rules...

In 2018, the European Council and the UK and Spanish governments each proposed to introduce a Digital Services Tax (DST), to be levied on the revenue of large digital platform companies earned from advertising, online intermediation, and/or the transmission of data. We offer a rationalization of...

In this paper, I use difference-in-differences regressions to measure how the debt tax shield affects the capital structure of a company. By comparing the financial leverage of treatment and control companies before and after the introduction of an equity tax shield, I infer the impact of the...

We present a new model of tax induced transfer pricing as an alternative to the oft-used concealment model. Inspired by interviews with practitioners, we consider a large multinational firm which is audited by the tax authority in the high-tax location. When this country adjusts the transfer...

We analyze the optimal tax choices of a revenue-maximizing government that levies taxes from firms of which the true degree of mobility is ex ante unknown. Differential tax treatment of immobile and mobile firms is ruled out, but the government may learn from the firms’ location responses to...
