Good Provision

I develop a dynamic model with forward looking agents, and show that social pressure is effective in generating provision in a public good game: after a small group of agents start contributing to the public good, other agents decide to contribute as well due to a fear of being punished, and this generates contagion in the network. In contrast to earlier models in the literature, contagion happens fast, as part of the best response of fully rational individuals. The network topology has implications for whether contagion starts and the extent to which it spreads. I find conditions under which an agent decides to be the first to contribute in order to generate contagion in the network, as well as conditions for contribution due to a self-fulfilling fear of social pressure.

Good Provision

In this paper, we propose a game in which each player decides with whom to establish a costly connection and how much local public good is provided when benefits are shared among neighbors. We show that, when agents are homogeneous, Nash equilibrium networks are nested split graphs. Additionally, we show that the game is a potential game, even when we introduce heterogeneity along several dimensions. Using this result, we introduce stochastic best reply dynamics and show that this admits a unique and stationary steady state distribution expressed in terms of the potential function of the game. Hence, even if the set of Nash equilibria is potentially very large, the long run predictions are sharp.

AbstractI develop a model of inequality aversion and public goods that allows the marginal rate of substitution to be variable. As a theoretical foundation, utility function of the standard public goods model is nested in the Fehr-Schmidt model. An individual’s contribution function for a public good is derived by solving the problem of kinky preference and examining both interior and corner solutions. Results show that the derived contribution function is not monotonic with respect to the other individual’s provision. Thus, the model can be used to explain empirical evidence for the effect of social comparison on public-good provision.
