We present a simple mechanism that can be implemented in a simple experiment. In a modified trust game, the allocator can offer to pay the investor to cooperate. The mechanism is successful at implementing efficient outcomes: participants manage to achieve an efficient outcome, when this is...

Abstract While most scholars agree that prosocial motivations have replaced monetary incentives in open online communities, they often argue that these other-regarding motivations are based on exogenous preferences, and are the prerogative of the contributors. With the help of the French...

Cartels are inherently instable. Each cartelist is best off if it breaks the cartel, while the remaining firms remain loyal. If firms interact only once, if products are homogenous, if firms compete in price, and if marginal cost is constant, theory even predicts that strategic interaction...

Providing public goods is hard, because providers are best off free-riding. Is it even harder if one group's public good is a public bad for another group or, conversely, gives the latter a windfall profit? We experimentally study public goods provision embedded in a social context and find that...

In this paper we consider the problem of sharing water from a river among a group of agents (countries, cities, firms) located along the river. The benefit of each agent depends on the amount of water consumed by the agent. An allocation of the water among the agents is efficient when it...

In this paper, we investigate the optimal taxation policy in a differential oligopoly game where the competing firms share the access to a productive renewable resource. We show that, in a linear Feedback Nash Equilibrium of the game, a linear Markov tax, imposed on the output, and specified as...

This paper develops a mechanism to correct production externalities between several parties, such as externalities motivating environmental policy between countries, using asset ownership. Efficiency can be obtained if each party retains less than the full share of their own gain from resource...

We consider a simple dynamic model of environmental taxation that exhibits time inconsistency. There are two categories of firms, Believers, who take the tax announcements made by the Regulator to face value, and Non-Believers, who perfectly anticipate the Regulator's decisions, albeit at a...
