Tax policy in general and international income tax policy in particular has long been a subject of discussion and argument by tax philosophers, economists, and lawyers. Theories have often been introduced to support the establishment of new tax systems, to justify existing ones, or to call for...

Today we live in a globalizing economy: national open markets are steadily developing towards a global market. Within the European Union, the internal market without internal frontiers has been established. However, the fiscal sovereignty of nation states remains limited to economic activities...

Switzerland is a prime location for both domestically owned as well as foreign-owned multinational enterprises (MNEs). In this paper, we review the literature on MNE activity with respect to its main fundamental (non-policy) drivers, the non-fiscal consequences of MNEs for various economic...

This paper examines location choices of multinational enterprises (MNEs). We particularly focus on the consequences of double taxation treaties (DTTs) and corporate profit taxes on the probability to choose a location. DTTs have become a key policy instrument used by countries to regulate...

What are the macroeconomic implications of re-allocating taxing rights away from source countries (where goods are produced) to market countries (where goods are consumed) and introducing minimum rates in international profit taxation? We assess this question in a dynamic macroeconomic model...

This policy note summarises the main findings of our recent research on the effects of labour and corporate taxation on international trade, and discusses their policy implications. The first major finding is that labour taxes do not seem to affect imports, while their effect on exports is...

How did the rise of multinational enterprises (MNEs) put pressure on the prevailing international corporate tax framework? MNEs, and firms with market power, are not new phenomena, nor is the corporate income tax, which dates to the early 20th century. This prompts the question, what is...

How countries tax the profits of multinational enterprises has become hopelessly outdated. The recent OECD/G20 Base Erosion and Profit Shifting Project has left the existing international corporate taxation framework essentially intact. Perhaps it is time to consider a truly fundamental reform...

What happens when sovereign governments coordinate their tax policies? This is an important research topic in government and economics. We focus on implications of re-allocating taxing rights away from source countries (where goods are produced) to market countries (where goods are consumed) and...

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...
