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...

We consider a world in which countries apply optimal taxes on mobile capital and savings (like in Bucovetsky and Wilson, 1991). Firms and savers may underreport income in order to avoid or evade taxation. We show that, even in the presence of underreporting, the equilibrium under tax competition...

In its Public Consultation Document, the OECD discusses the introduction of effective minimum taxes on multinational firm profits (the so-called GLOBE: "global anti-base erosion" proposal). In this paper, we make three distinct contributions. First, we discuss the policy rationale for the...

The Inclusive Framework of the OECD/G20 currently discusses the internationally coordinated introduction of effective minimum taxes on multinational firm profits. This so-called GLOBE (global anti-base erosion) proposal is inspired by the GILTI and BEAT regimes of the 2017 US tax reform. It...

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...

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,...

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...
