Case studies of cartels and recent theory suggest that repeated communication is key for stable cooperation in environments where signals about others' actions are noisy. However, empirically the exact role of communication is not well understood. We study cooperation under different monitoring...

We design a transboundary public goods (TPG) game, in which participants have simultaneous interaction within and between groups. We design the TPG game under an infinitely repeated situation in order to explore the types of strategies that participants employ in infinitely repeated games. We...

This paper studies a novel setting in game theory: a player may learn new actions over time by observing the opponent's play. We investigate the impact of such learning behavior in the context of finitely repeated games. In contrast to related literature such as Kreps et al. (1982), we provide a...

The traditional mechanism of finding Nash equilibria presumes that economic actors are capable of performing computations which even computers would take far too long to perform. A decentralized and parallel process of interactions between simple economic actors is presented as a more plausible...

We experimentally explore indefinitely repeated contests. Theory predicts more cooperation, in the form of lower expenditures, in indefinitely repeated contests with a longer expected time horizon, and our data support this prediction, although this result attenuates with contest experience....

Case studies of cartels and recent theory suggest that communication promotes cooperation under imperfect monitoring, where actions can only be observed with noise. We report the results of a laboratory experiment designed to answer the question how much communication is needed to sustain...

Greve and Okuno-Fujiwara (2009) studies the Voluntarily Separable Repeated Prisoner's Dilemma (VSRPD); a random matching game where an agent voluntarily chooses whether to terminate his/her current partnership or not. Based on the VSRPD, we consider the hybrid society, in which some agents are...

Reanalyzing 12 experiments on the repeated prisoner's dilemma (PD), we robustly observe three distinct subject types: defectors, cautious cooperators and strong cooperators. The strategies used by these types are surprisingly stable across experiments and uncorrelated with treatment parameters,...

This paper investigates the way in which adaptive players behave in the long run in finitely repeated games. Each player assigns subjective payoff assessments to his own actions and chooses the action which has the highest assessment at each of his information sets. After receiving payoffs,...

This paper uses a laboratory experiment to study beliefs and their relationship to action and strategy choices in finitely and indefinitely repeated prisoners' dilemma games. We find subjects' beliefs about the other player's action are accurate despite some systematic deviations corresponding...
