In this paper the role of information asymmetries between regions and a centralized authority is analyzed. In a model with inter-regional externalities due to capital mobility and a source-based tax instrument, we first derive conditions for which the optimum can be implemented by an adequately...

We examine the efficiency properties of labor taxation. A spatial model of an economy is introduced whose key feature is a new approach to restricted labor mobility. We characterize the efficient allocation of labor and properties of a decentralized equilibrium. An efficient allocation of labor...

This paper examines information sharing between governments in an optimaltaxation framework. We present a taxonomy of alternative systems of international capital-income taxation and characterize the choice of tax rates and information exchange. The model reproduces the conclusion of the...

The EU Commission is advocating a common consolidated tax base for the corporate income tax, accompanied by a revenue sharing mechanism based on formula apportionment. We analyse tax competition in such a regime, focussing on the interaction between the definition of the tax base and the...

We analyze tax competition between large and asymmetric countries and derive conditions under which countries assist foreign authorities in collecting tax revenues via information exchange. It turns out that voluntary exchange of information is a Nash equilibrium between asymmetric countries,...
