game-theory-prisoners-dilemma

Cooperation breaks down because defection is individually rational despite mutual cooperation yielding better collective outcomes. This prisoner's dilemma dynamic occurs when temptation to defect overrides shared incentives, requiring structural changes like transparency or enforcement to align individual and collective rationality.

Verify a prisoner's dilemma by checking three conditions: mutual cooperation dominates mutual defection, defection is individually rational regardless of the other party's choice, and real temptation to defect exists. The analysis confirms structural fit before prescribing incentive changes.

Game theory analysis distinguishes one-shot interactions where cooperation is impossible from repeated interactions where it is potentially stable. By assessing discounting logic and the shadow-of-the-future, it maps trigger conditions for defection and evaluates whether punishment is credible.

Fix collective underinvestment by applying structural prescriptions that change incentives so cooperation becomes individually rational. Approaches include repeating the game, increasing transparency, adjusting payoffs, reducing temptation, building shared identity, or adding enforcement mechanisms.

This cooperation analysis applies directly to price wars, subsidy races, and any scenario where everyone defects despite cooperation being collectively better. It diagnoses the incentive structure, maps payoffs, and produces ranked prescriptions to align individual incentives with collective action.

Do not use a prisoner's dilemma framework when the situation fails the three structural conditions: mutual cooperation dominance, defection as individually rational, and real temptation to defect. If these criteria are absent, the diagnosis will not match and prescriptions will not address the actual incentive problem.
