Is Prisoner’s Dilemma Nash equilibrium?

In this game, two criminals are arrested and each is held in solitary confinement with no means of communicating with the other. … The Nash equilibrium in this example is for both players to betray each other.

What does Prisoner’s Dilemma have to do with oligopoly?

The prisoner’s dilemma is a type of game that illustrates why cooperation is difficult to maintain for oligopolists even when it is mutually beneficial. In this game, the dominant strategy of each actor is to defect. However, acting in self-interest leads to a sub-optimal collective outcome.
