We develop a two-region model where the decentralized provision of spillover goods can be financed by means of taxes or user fees. In order to enforce the fees regions have to invest in exclusion. We show that a decentralized solution tends to be inefficient. There will be over-investment in...

This paper examines information sharing between governments in an optimal taxation 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 private provision of public goods suffers from two potential types of efficiency failures: non-optimal output levels of the public good (quantity problem) and an inefficient mix of contributors and non-contributors (sorting problem). Embedding the provision game into a contest that rewards...

We analyze if and how multi-prize Tullock contests can be used to guarantee efficient contributions to a public good when agents are heterogenous both with respect to the costs of production of the public good and with respect to the utility from its consumption. With two types of individuals,...

Usually, groups increase their productivity by the specialization of their group members. In these cases, group output is no longer simply a sum of individual outputs. We analyze contests with group-specific public goods that allow for different degrees of complementarity between group members'...
