An Evolutionary Game-Theoretic Perspective on the Prisoner’s Dilemma

Öz

The Prisoner’s Dilemma is the canonical model in microeconomics for the tension between individual rationality and collective welfare. Standard game-theoretic analysis predicts that mutual defection is the unique Nash equilibrium, despite being Pareto-dominated by mutual cooperation. This study revisits the Prisoner’s Dilemma through the lens of evolutionary game theory, in which strategy frequencies in a population evolve according to differential payoffs. We derive the replicator equation for the one-shot game and show analytically that the all-defectors state is the unique asymptotically stable equilibrium and the unique evolutionarily stable strategy. We then extend the analysis to the infinitely repeated game with continuation probability , contrasting the reactive strategy Tit-for-Tat (TFT) with Always Defect (ALLD). We derive the critical continuation probability  above which TFT becomes an ESS within the restricted two-strategy space (that is, resists invasion by ALLD), the bistable replicator dynamics that emerge in that regime, and a closed-form expression for the unstable interior equilibrium  that separates the two basins of attraction. The bifurcation structure is interpreted economically as a precise formalisation of Axelrod’s “shadow of the future.” All results are derived from first principles and illustrated with numerical examples.
