Epstein (1998) demonstrates that in the demographic Prisoner's Dilemma game it is possible to sustain cooperation in a repeated game played on a finite grid, where agents are spatially distributed and of fixed strategy type ('cooperate' or 'defect'). We introduce a methodology to formalize the...

A distributed system model is studied, where individual agents play repeatedly against each other and change their strategies based upon previous play. It is shown how to model this environment in terms of continuous population densities of agent types. A complication arises because the...

The present paper considers the issue of High Frequency Trading (HFT) regulation. Rather than discussing macro-level effects of HFT that are still under debate (Sornette & Von der Becke, 2011) its analysis focuses on the issue of regulation from the perspective of HFT firms. Assuming that HFT...

Two pairs of two participants each interact repeatedly in two structurally independent but informationally linked Prisonerś Dilemma games. Neither pair receives feedback about past choices by their own partner but is fully informed about the choices by the other pair. Considering this as a...

Intelligence and personality significantly affect social outcomes of individuals. We study how and why these traits affect the outcome of groups, looking specifically at how these characteristics operate in repeated interactions providing opportunity for profitable cooperation. Our experimental...

Intelligence affects social outcomes of groups. A systematic study of the link is provided in an experiment where two groups of subjects with different levels of intelligence, but otherwise similar, play a repeated prisoner's dilemma. The initial cooperation rates are similar, it increases in...

Unlike previous attempts to implement cooperation in a prisoners' dilemma game with an infinite horizon in the laboratory, we focus on extended prisoners' dilemma games in which a second (pure strategy) equilibrium allows for voluntary cooperation in all but the last round. Our four main...

We study framing effects in repeated social dilemmas by comparing payoff-equivalent Give- and Take-framed public goods games under varying matching mechanisms (Partners or Strangers) and levels of feedback (Aggregate or Individual). In the Give-framed game, players contribute to a public good,...

This paper aims to analyze subjects' behavior in an experiment on evolutionary process of prisoners' dilemma game. The experiment has been designed by using sixteen one-shot prisoners' dilemma games with payoffs perturbation and random matching players under perfect information. The subjects of...

Option to leave is a double-edged sword in the repeated prisoner's dilemma paradigm. We first show that too much breakup is not necessary in subgame perfect equilibrium distribution. We demonstrate on examples of well-known cooperation inducing solutions that, once an invasion with mixed...
