This paper develops a model of tax competition with three countries, which initially form a union where countries refrain from using different tax rates in different sectors of the economy. We study the impact of one country leaving the union. We show that the introduction of discriminatory...

We analyze tax competition between two countries of unequal size trying to attract a foreign-owned monopolist. When regional governments have only a lump-sum profit tax (subsidy) at their disposal, but face exogenous and identical transport costs for imports, then both countries will always...

This paper analyzes measures that limit firms' profit shifting activities in a model that incorporates heterogeneous firm productivity and monopolistic competition. Such measures, e.g. thin capitalization rules, have become increasingly widespread as governments have reacted to growing profit...

This paper analyses tax competition between a unionised and a non-unionised country for the location of an outside firm. We show that unionisation offers an extra incentive for the government to attract a foreign competitor to a concentrated domestic market, in order to affect the behaviour of...

This paper studies tax policy interaction among local governments for both mobile and immobile tax bases. We exploit exogenous changes in the local tax setting of German municipalities due to participation in state debt reduction programs to learn about the size, scope and nature of strategic...

This survey summarizes the state and development of European tax policy, in particular discussing the harmonization progress in direct as well as indirect taxes. Based on an overview over the theoretical and empirical literature on tax competition, we further ask whether increased tax...

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,...

How do countries compete for mobile tax base when they lack precise information on how tax rates affect the tax base? We present a multi-period version of a classic tax competition model in which countries set source-based taxes under incomplete information on the tax base elasticity. This...

Heterogeneous firm productivity seems to provide an argument for governments to pursue 'pick-the-winner' strategies by subsidizing highly productive firms more, or taxing them less, than their less productive counterparts. We appraise this argument by studying the optimal choice of effective tax...

Many countries have introduced patent box regimes in recent years, offering a reduced tax rate to businesses for their IP-related income. In this paper, we analyze the effects of patent box regimes when countries can simultaneously use patent boxes and R&D subsidies to promote innovation. We...
