In this paper we ask whether recent claims that the US government should switch from the tax credit system to the exemption system are justified. We study corporate taxation in a model where international capital flows are either greenfield investment projects or acquisitions of existing firms,...

In this paper, we analyze tax competition in a model where investor firms have the choice between two types of investment, greenfield investment and mergers and acquisitions. We show that the coexistence of these two types of investment intensifies tax competition in comparison to the case where...

A widespread objection to the introduction of consumption tax systems claims that this would lead to high tax revenue losses. This paper investigates the revenue effects of a consumption tax reform in Germany. Our results suggest that the revenue losses would be surprisingly low. We find a...

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...

In this comment, we argue that — even in the model used by Hines — full deductibility of costs under the exemption system is incompatible with nationally optimal tax policy. We derive an optimality rule which suggests that cost apportionment rules are efficient. Our findings also imply that...

This paper analyses tax competition and tax coordination in a model where capital flows occur in the form of mergers and acquisitions, rather than greenfield investment. In this framework, we show that differences in residence based taxes do not necessarily distort international ownership...

This note provides a novel argument why countries may have incentives to allow for some profit shifting to low-tax jurisdictions. The reason is that a tightening of transfer pricing policies by high-tax countries may lead to more aggressive tax rate competition by low-tax countries.

Das bestehende Steuersystem wird häufig als ein Grund für die anhaltende Investitions- und Wachstumsschwäche in Deutschland angesehen. Daher wird insbesondere von Seiten deutscher Wirtschaftswissenschaftler eine konsumorientierte Umgestaltung des Steuersystems gefordert. Hingegen weisen...

Kapitalmarktorientierte Unternehmen in Deutschland orientieren sich in zunehmendem Maße an der Konzernsteuerquote. Diese unterscheidet sich in wesentlichen Aspekten von den in der Forschung gängigen Maßen der e¤ektiven Besteuerung, die auf dem neoklassischen Investitionsmodell basieren. Dies...
