When providing public goods through voluntary contributions, a donor may introduce unilateral matching in order to reduce underprovision of the public good and thus inefficiency. By itself, however, matching benefits the donor but harms the recipient. We apply Cornes and Hartley's aggregative...

This paper explores the outcome of an international environmental agreement when the governments are elected by their citizens. It also considers a voter's incentives for supporting candidates who are less green than she is. In the extreme case of 'global' pollution, the elected politicians pay...

In many empirically relevant situations agents in different groups are affected by the provision of a public characteristic in divergent ways: While for one group it represents a public good, it is a public bad for another group. Applying Cornes' and Hartley's (2007) Aggregative Game Approach,...

Using the aggregative game approach as developed by Cornes and Hartley (2003, 2007) this paper analyzes the conditions under which matching mechanisms in a public good economy lead to interior matching equilibria in which all agents make strictly positive flat contributions to the public good....

Matching mechanisms are regarded as an important instrument to bring about Pareto optimal allocations in a public good economy and to cure the underprovision problem associated with private provision of public goods. The desired Pareto optimal interior matching equilibrium, however, emerges only...
