In repeated normal-form games, simple penal codes (Abreu 1986, 1988) permit an elegant characterization of the set of subgame-perfect outcomes. We show that the logic of simple penal codes fails in repeated extensive-form games. We provide two examples illustrating that a subgame-perfect outcome...

International agreements to protect the global environment are typically difficult to reach. In principle they should be profitable for all players involved in the negotiation. Even when they are profitable, however, they are often unstable due to the incentive to free-ride (enjoying the clean...

We investigate the outcome of bargaining when a player’s pay-off from agreement is risky. We find that a risk-averse player typically increases his equilibrium receipts when his pay-off is made risky. This is because the presence of risk makes individuals behave 'more patiently' in bargaining....

We introduce strategic waiting in a global game setting with irreversible investment. Players can wait in order to make a better informed decision. We allow for cohort effects and discuss when they arise endogenously in technology adoption problems with positive contemporaneous network effects....

We use experiments to analyze what type of communication is most effective in achieving cooperation in a simple collusion game. Consistent with the existing literature on communication and collusion, even minimal communication leads to a short run increase in collusion. However, in a limited...

The theory of monotone comparative statics and supermodular games is presented as the appropriate tool to model complementarities. The approach, which has not yet been fully incorporated into the standard toolbox of researchers, makes the analysis intuitive and simple, helps in deriving new...

This Paper characterises the unique Markov equilibrium in the sequential move, finite horizon pricing duopoly with discounting. Simple, short cycles repeat until the last two periods. For discount factors above 0.75488, there are three-period reaction function cycles and below 0.75488,...

This paper studies how constraints on the timing of actions affect equilibrium in intertemporal coordination problems. We show that while the possibility of waiting longer for others'’ actions helps agents to coordinate in the good equilibrium, the option of delaying one’s' actions harms...

Probabilistic measures of a priori voting power are useful tools to asses actors' influence on collective decision-making either for the purpose of designing a voting organ or to model particular policy cases. This paper makes an attempt to reduce a dynamic voting process into a cooperative...
