We model countries' choice of greenhouse gas (GHG) emissions as a dynamic game. Emissions generate immediate benefits to the emitting country but also increase atmospheric GHG concentrations that negatively affect present and future welfare of all countries. Because there are no international...

This paper analyzes the setting of national patent policies in the global economy. In the standard model with free trade and social-welfare-maximizing governments à la Grossman and Lai (2004), cross-border positive policy externalities induce individual countries to select patent strengths that...

Recent international climate negotiations suggest that complete agreements are unlikely to materialize. Instead, partial cooperation between like-minded countries appears a more likely outcome. In this paper we analyze the effects of such partial cooperation between like-minded countries. In...

We examine international cooperation on technological development as a supplement to, or an alternative to, international cooperation on emission reductions. R&D should be increased beyond the non-cooperative level if (i) the technology level in one country is positively affected by R&D in other...

Most existing empirical evidence on the impact of profit taxation on multinational firm activity is based on cross-country data. One major drawback of such data is that countries differ not only with regard to taxes but along other dimensions which might be hard to capture by means of observable...

This paper argues that profit-shifting activities of multi-jurisdictional enterprises (MJE) are maintained under a tax system of consolidation and formula apportionment (FA). A theoretical model discusses how an MJE can exploit its impact on the definition of the consolidated group...

Thin capitalization rules have become an important element in the corporate tax systems of developed countries. This paper sets up a model where national and multinational firms choose tax-efficient financial structures and countries compete for multinational firms through statutory tax rates...

Recent empirical research documents a tendency of affiliates of multinational enterprises to bunch around zero reported profit. Setting up a model that allows for profitable and loss-making affiliates of multinationals, we show that profit shifting to a low-tax country as well as a loss-related,...

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...

Intellectual Property Rights (IPR) protect firms from imitation and are considered crucial to promote innovation and technological diffusion. This paper examines the impact of IPR on import sourcing decisions of multinationals. We consider a framework in which firms offshore production of an...
