In Game Theory, the 'Prisoner's Dilemma' is a classic scenario that demonstrates why two completely rational individuals might not cooperate, even if it appears that it is in their best interest to do so, often leading to:
- A Pareto optimal outcome for both
- A suboptimal Nash Equilibrium where both parties end up worse off
- A zero-sum game with a clear winner and loser
- A perfectly competitive market structure
Answer: A suboptimal Nash Equilibrium where both parties end up worse off
The Prisoner's Dilemma illustrates the conflict between individual rationality and collective benefit. Because each player acts out of self-interest and fear of being exploited by the other, they both choose to defect (e.g., confessing to a crime or starting a price war). This results in a Nash Equilibrium that is strictly worse for both compared to if they had successfully cooperated.
