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...

This Paper studies how economic integration affects transfer pricing, tax policy and welfare, when multinationals are taxed either according to formula apportionment (FA) or separate accounting (SA). It is shown that economic integration induces multinationals to lower their transfer prices...

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...

Many countries have introduced patent box regimes in recent years, offering a reduced tax rate to businesses for their IP-related income. In this paper, we analyze the effects of patent box regimes when countries can simultaneously use patent boxes and R&D subsidies to promote innovation. We...

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...

The paper analyzes the effects of a regionally coordinated profit tax in a model with three active countries, one of which is not part of the union, and a globally mobile firm. We show that regional tax coordination can lead to two types of welfare gains. First, for investments that would take...
