This paper analyses the formation of international environmental agreements (IEAs) under uncertainty, focusing on the role of learning and risk aversion. It bridges two strands of literature: one focused on the role learning for the success of IEA formation when countries are risk neutral and...

The ultimatum game is a sequential-move bargaining game in which a “giver” offers a “taker” a share of a monetary pie. The predicted subgame perfect equilibrium is for rational givers to offer the smallest possible share, and for rational takers to accept. Experimental trials conducted...

For a fixed game and a type structure that admits a common prior, Action Independence states that the conditional beliefs induced by the common prior do not depend on the player's own strategy. It has been conjectured that Action Independence can be behaviorally characterized by means of a...

We study the long-run behavior of an economy where agents who are heterogeneous with respect to risk attitudes can either earn a certain income or enter a risky rent seeking contest. In contrast with standard evolutionary game theory, we distinguish between utility and material payoffs, and...

It is commonly assumed that friendship should generally benefit agents' ability to tacitly coordinate with others. However, this has never been tested on two "opposite poles" of coordination, namely, games of strategic complements and substitutes. We present an experimental study in which...
