Die finanzwissenschaftliche Theorie hat lange Zeit die Auffassung unterstützt, dass ausländische wie inländische Einkommen besteuert werden sollten (Anrechnungsverfahren). Mittlerweile haben viele empirische Studien ergeben, dass es gesamtwirtschaftlich effizienter sei, ausländische...

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 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...

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...

In this paper, we consider optimal tax enforcement policy in the presence of profit shifting towards tax havens. We show that, under separate accounting, tax enforcement levels may be too high due to negative fiscal externalities. In contrast, under formula apportionment, tax enforcement is...

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...

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...
