This paper studies adaptive learning in the class of weighted network games. This class of games includes applications like research and development within interlinked firms, crime within social networks, the economics of pollution, and defense expenditures within allied nations. We show that...

This paper analyzes the private provision of public goods where consumers interact within a fixed network structure and may benefit only from their direct neighbors’ provisions. We present a proof for existence and uniqueness of a Nash equilibrium with general best-reply functions. Our...

We study a situation where, as a consequence of private information, agents do not have the incentive to invest in a public good if they are unable to have prior discussion with their partners. We show that in a voluntary contribution mechanism with cheap talk, any finite message space does not...

How can we maximize the common good? This is a central organizing question of public policy design, across political parties and ideologies. The answer typically involves the provisioning of public goods such as fresh air, national defense, and knowledge. Public goods are costly to produce but...

We study a public goods game with heterogeneous agents who care about their own payoff as well as of the player who receives the lowest payoff. The weight on own payoff varies across players, and is private information. We first develop a theoretical model and then test the predictions of our...

We examine a voluntary participation game in public good provision in which each agent has a demand level for the public good. The agent's demand level is the minimum level of the public good from which she can receive a positive benefit. In this game, there exists a subgame perfect Nash...

We consider a (pure) public goods provision problem with voluntary participation in a quasi-linear economy. We propose a new hybrid solution concept, the free-riding-proof core (FRP-Core), which endogenously determines a contribution group, public goods provision level, and how to share the...

We present a natural environment that sustains full cooperation in one-shot social dilemmas among a finite number of self-interested agents. Players sequentially decide whether to contribute to a public good. They do not know their position in the sequence, but observe the actions of some...

We modify the provision point mechanism by introducing reward money, which is distributed among the contributors in proportion to their contributions only when the provision point is not reached. In equilibrium, the provision point is always reached as competition for reward money and preference...

In this paper I analyze a dynamic moral hazard problem in teams with imperfect monitoring in continuous time. In the model, players are working together to achieve a breakthrough in a project while facing a deadline. The effort needed to achieve such a breakthrough is unknown but players have a...
