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 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...

We exploit the 2017 US tax reform to learn about the tax-competitiveness of US multinational corporations (MNCs) relative to their international peers. Matching on the propensity score, we compare pairs of similar US and European firms listed on the S&P500 or StoxxEurope600 in a...

We address the role of labor cost differentials for national tax policies. Using a simple theoretical framework with two countries competing for a mobile firm, we show that in a bidding race for FDI, it is optimal for governments to compensate firms for international labor cost differentials....

If conventional instruments of strategic trade policy are unavailable, the system of foreign profit taxation and transfer price guidelines may serve as surrogate policy instruments. In this paper, I consider a model where firms from two countries compete with each other on a third market. I...

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 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...

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...

Multinational firms are known to shift profits and countries are known to compete over shifty profits. Two major principles for corporate taxation are Separate Accounting (SA) and Formula Apportionment (FA). These two principles have very different qualities when it comes to preventing profit...

We develop a positive model of multinational firm behavior and analyze a firm’s incentive to transfer an intellectual property (IP) right of uncertain value offshore ex ante, i.e. before its success or failure is realized. With an asymmetric treatment of losses in the home country, the...
