The prisoner’s dilemma is a scenario in which two individuals are being interrogated regarding a potential crime they may have committed. If both individuals confess, they will each receive a 5-year prison sentence. If neither confesses, they will each receive a 3-year prison sentence. However, if one person confesses while the other remains silent, the confessor will only receive a 1-year sentence while the other person will receive a 10-year sentence. This scenario is often used to illustrate the benefits of cooperation over individual action. Another important concept to understand is “externality,” which refers to the impact of one person’s actions on others. This impact can be positive, such as when a neighbour improves their yard and enhances the overall appearance of the neighbourhood. Conversely, it can also be negative, such as when a factory pollutes the water and causes illness among the population.
The Prisoner’s Dilemma is a logic problem commonly used to illustrate the impact of cooperative behaviour. It involves two prisoners who are interrogated separately regarding their involvement in a crime. The potential outcomes are as follows: If both confess, they will each receive a 5-year sentence. If neither confesses, they will each receive a 3-year sentence. If one confesses while the other remains silent, the confessing prisoner will receive a 1-year sentence, while the silent prisoner will receive a 10-year sentence. This dilemma demonstrates that individuals may choose not to cooperate, even if it is in their best interest, due to the fear of trusting the other person and facing potential consequences. For instance, consider two competing companies in the same market. If they both agree to maintain high prices, they will both generate more profit. However, if one company decides to lower its prices, it will attract more customers and earn more profit than the other company. This creates a dilemma where both companies could benefit from cooperation, but they may lack sufficient trust in each other to do so. Another example is pollution. A factory may gain from producing goods, but the resulting pollution can harm the environment and nearby communities. This represents a negative externality, as the factory causes harm without compensating those affected. Conversely, a homeowner who beautifully landscapes their property may enhance the value of neighbouring homes. This is a positive externality, as the homeowner benefits others without receiving compensation.
