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.

We present a rigorous, yet elementary, demonstration of the existence of a unique Lindahl equilibrium under the assumptions that characterize the standard n-player public good model. Indeed, our approach, which exploits the aggregative structure of the public good model, lends itself to a...
