The prisoner's dilemma is a paradox in decision analysis in which two individuals acting in their own self-interests do not produce the optimal outcome.A prime example of game theory, the prisoner's dilemma was developed in 1950 by RAND Corporation mathematicians Merrill Flood and Melvin Dresher during the Cold War (but later given its name by the game theorist Alvin Tucker). Some have speculated that the prisoner's dilemma was crafted to simulate strategic thinking between the U.S.A. and U.S.S.R. during the Cold War.Today, the prisoner's dilemma is a paradigmatic example of how strategic thinking between individuals can lead to suboptimal outcomes for both players.
Definition
The Prisoner's Dilemma is a paradox in decision analysis where two individuals acting in their own self-interest do not produce the optimal outcome. It is a classic example in game theory, illustrating how strategic thinking between individuals can lead to suboptimal results for both parties.
Origin
The Prisoner's Dilemma was developed by mathematicians Merrill Flood and Melvin Dresher at the RAND Corporation during the Cold War, and later named by game theorist Albert W. Tucker. It is speculated that the dilemma was designed to simulate the strategic thinking between the United States and the Soviet Union during the Cold War.
Categories and Features
The Prisoner's Dilemma can be categorized into single-play and repeated-play games. In a single-play game, participants make a decision only once, whereas in repeated-play games, participants make multiple decisions, which can lead to different strategies and outcomes. In single-play games, individuals tend to choose the strategy that benefits them the most, even if it leads to a suboptimal collective outcome. In repeated-play games, cooperation may emerge as a strategy, as participants can adjust their strategies based on the observed behavior of others.
Case Studies
A classic example is the arms race between the United States and the Soviet Union during the Cold War. Both sides sought to gain a security advantage by increasing their arsenals, leading to massive resource waste and heightened tensions. Another example is price wars between companies. Two companies might lower prices to gain market share, but this often results in reduced profits, ultimately harming both parties.
Common Issues
Investors often misunderstand the potential for cooperation in the Prisoner's Dilemma. While cooperation may be feasible in repeated-play games, it is often difficult to achieve in single-play games. Additionally, the Prisoner's Dilemma is not applicable to all decision-making scenarios, and understanding its scope is crucial.
