In small groups, norm enforcement is achieved through mutual punishment and reward. In large societies, norms are enforced by specialists such as government officials. However, not every public cause is overseen by states, for instance those organized at the international level. This paper shows...

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....

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...

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...

If the equilibrium generated by a matching mechanism is to be the desired Pareto optimal outcome, it is necessary for every player to be at an interior solution at that equilibrium. Using the aggregative game approach developed by Cornes and Hartley (2003, 2007), this paper analyzes the...

Matching mechanisms are widely regarded as providing a promising way to cure the public good underprovision problem, but the Pareto optimal interior matching equilibrium emerges only under very special conditions. However, we show that public good underprovision is normally avoided.
