Influence Networks and Public Goods

We consider a model of social interactions in which agents are assumed to acquire information from others through a certain sampling process that generates an influence network. These networks comprise a wide array of options depending on the level of correlation assumed between agents' in and out degree. We study the provision of public goods in influence networks and show that the equilibrium (of the corresponding best-shot game) always exists and it is unique. We derive further insights for this problem by performing a comparative statics analysis.
