Constrained public goods in networks

This paper analyses the private provision of public goods where agents interact within a fixed network structure and may benefit only from their direct neighbours' provisions. We generalise the public goods in the networks model of Bramoulle and Kranton [J. Econ. Theory 135 (2007), pp. 478-494] to allow for constrained provision. In so doing, we characterise Nash equilibria with no intermediate contributors.
