We use a novel experimental design to reliably elicit subjects’ strategies in an infinitely repeated prisoner’s dilemma experiment with perfect monitoring. We find that three simple strategies repre‑ sent the majority of the chosen strategies: Always Defect, Tit‑for‑Tat, and Grim. In addition, we identify how the strategies systematically vary with the parameters of the game. Finally, we use the elicited strategies to test the ability to recover strategies using statistical methods based on…

The Impact of Monitoring in Infinitely Repeated Games: Perfect, Public, and Private
TLDR
It is found that the subjects sustain cooperation in every treatment, but that their strategies differ across the three treatments, and that the strategies under imperfect monitoring are both more complex and more lenient than those under perfect monitoring.
It’S Payback Time: New Insights on Cooperation in the Repeated Prisoners’ Dilemma

Forgiveness is an Adaptation in Iterated Prisoner's Dilemma with Memory
TLDR
The findings show that forgetting and forgiving defectors is the supreme memory management strategy in a competitive, heterogeneous environment, and is just the opposite for homogeneous and heterogeneous ones, opposing the existing literature in IPD.
Predicting Cooperation with Learning Models∗
We use simulations of a simple learning model to predict cooperation rates in the experimental play of the indefinitely repeated prisoner’s dilemma. We suppose that learning and the game parameters

TLDR
Out of 60 ex ante plausible specifications, the selected model uses the six strategies described in Dal Bo and Frechette (2018), and allows the distribution of trembles to vary by strategy.
Cooperation in Indefinite Games: Evidence from Red Queen Games
We test whether the length of an indefinite horizon, or that the horizon is indefinite as opposed to finite, affects cooperation in repeated 3x3 Red Queen Games. With our participant population, and
Direct reciprocity between individuals that use different strategy spaces
In repeated interactions, players can use strategies that respond to the outcome of previous rounds. Much of the existing literature on direct reciprocity assumes that all competing individuals use
Strategy revision opportunities and collusion
This paper studies whether and how strategy revision opportunities affect levels of collusion in indefinitely repeated two-player games. Consistent with standard theory, we find that such

A usual criticism of the theory of infinitely repeated games is that it does not provide sharp predictions since there may be a multiplicity of equilibria. To address this issue, we present
