Exogenously given reputational information is known to improve cooperation. This paper experimentally studies how people create such information through reporting of partner's action choices, and whether the endogenous monitoring helps sustain cooperation, in an indefinitely repeated prisoner's...

We extend public goods game and design transboundary public goods game which players receive more information from the local group, and marginal return per capital (MPCR) is heterogeneous across local groups that high MPCR among local groups and low MPCR among counter groups. We experimentally...

We experimentally analyze the effect of endogenous group formation on the type of sanctioning institutions emerging in a society. We allocate subjects to one of two groups. Subjects play a repeated public goods game and vote on the sanctioning system (formal or informal) to be implemented in...

We study how the objective of the contributions affects the willingness to contribute to real-life public goods. We conducted three treatments of a fundraising experiment among religious Jewish students in which the contributions were assigned to finance sustainable supplies and the ongoing...

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...

We experimentally examine the efficacy of a novel pre-play institution introduced by Calcagno et al. (2014) in a well-known coordination game—the minimum-effort game—in which coordination failures are a robust and persistent phenomenon. This new institution allows agents to communicate while...

This paper proposes a new communication protocol in coordination games with binary actions and Pareto-ranked equilibria, which comes from an option to delay. In the first period, players choose between committing to the risk-dominant (safe) action in the game or delaying their choices until a...

A large literature in behavioral economics has emphasized in the last decades the role of individual differences in social preferences (such as trust and altruism) and in influencing behavior in strategic environments. Here we emphasize the role of attention and working memory, and show that...

In dynamic environments where the strategic setting evolves across time, the specific rule governing the transitions can substantially alter the incentives agents face. This is particularly true when history‐dependent strategies are used. In a laboratory study, we examine whether subjects...
