Review Chapter 15, Table 15.4, Prisoner Dilemma. Suppose the game starts with both Jesse and Frank planning to “Stay Mum” in the lower right cell. Discuss how each player would evaluate the situation and decide whether to change decisions. If each player makes decisions to minimize the penalty, in which cell will this game end? Is there a Nash equilibrium?
Briefly explain the differences between the equilibrium concepts we discussed in game theory. What do we need to assume about people’s decision making to find equilibria?

- In business, sports, politics, and many other fields there are probably countless situations akin to the prisoner's dilemma where players acting in their own self-interest do not produce an ideal outcome. Likewise, some player dynamics also illustrate other game theory concepts like a game of chicken, credible threats/commitments, and other similar concepts.
