Forward looking measures like the well-known effective marginal tax rate developed by King and Fullerton (1984) are often criticized for not taking into account the complexity of the tax law. This paper derives a method of evaluating this kind of measure and of quantifying the bias resulting...

The standard tax theory result that investment should not be distorted is based on the assumption that profits are locally bound. In this paper we analyze the optimal tax policy when firms are internationally mobile. We show that the optimal policy response to increasing firm mobility may be...

The paper surveys some main results in the theory of capital income taxation in the open economy; reviews recent trends in international taxation, and discusses alternative blueprints for fundamental capital income tax reform from the perspective of an open economy faced with growing mobility of...

The recent international agreement on a minimum effective corporate tax rate marks a profound change in global tax arrangements. The appropriate level of that minimum, however, has been, and remains, extremely contentious. This paper explores the strategic responses to a minimum tax,...

This paper analyzes to which extent foreign plant ownership involves lower tax payments than domestic plant ownership. We employ a model of endogenous foreign subsidiary ownership to derive a set of empirically testable hypotheses about the differential taxation of foreign- and...

This article compares an ACE system with a CBIT system in an open economy. Using a realoption approach we show that, if a firm can decide when to invest, a tradeoff is found. According to traditional wisdom, a high-income firm investing in an ACE system faces a heavier tax burden at each...

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...

The EU Commission is advocating a common consolidated tax base for the corporate income tax, accompanied by a revenue sharing mechanism based on formula apportionment. We analyse tax competition in such a regime, focussing on the interaction between the definition of the tax base and the...

This paper studies the effects of globalization on the ability of governments to generate tax revenues for the financing of national welfare states. In this context, it summarizes the theoretical predictions of various economic models of tax competition between countries and discusses the role...

This paper deals with the effects of tax rate uncertainty on risk-neutral and risk-averse investment behavior. We analyze effects of stochastic tax rates on both real and financial investment. It emerges that under risk neutrality as well as under risk aversion, increased tax rate uncertainty...
