4. Game theory terminology Select the term that best describes each definition listed in the following table. Dominant Strategy Tit-for- tat Strategy Prisoners' Dilemma Nash Payoff Matrix Definition Equilibrium Collusion Game A case in which individually rational behavior leads to a jointly inefficient outcome A set of strategies (one for each player) in which each player's strategy is the best option for that player, given the chosen strategy of the player's opponents The event that occurs when agents in a game form an agreement about which strategies to implement A strategy in which a player cooperates until the other player defects and then defects until the other player cooperates again

7. Which of the following is not true of the “Battle of the Sexes" Game? a. The predicted outcome demonstrates how independent and rational play by players can quickly reach an agreement or a convergence of expectations concerning which strategy will be played by each player in equilibrium. b. The Battle of the Sexes Game can be used to depict a variety of situations where the players' interests do not precisely coincide, except for the fact that they both want to avoid the outcomes that would result from choosing different actions from one another. c. Players do not have a dominant strategy but playing “Boxing" say, is a best response to the other playing "Boxing" even if it doesn't give the player the payoff associated with his or her preferred alternative. d. Played only once, the outcome where each goes to their preferred venue cannot be Nash Equilibrium.

3) Recently, a major question in the news is why the Afghan army collapsed so quickly and unexpectedly in the face of the Taliban offensive. To help understand the situation, consider the following simplified model of the situation. Assume that there are two Afghan soldiers in the same unit. Each can stay and fight the Taliban or desert. If both stay and fight, they will win any battle against the Taliban, which each values at 100 utility. If either soldier deserts, the Taliban wins, which they each values at 0 utility. In addition, if only one soldier stays, that soldier will be killed by the Taliban, which he values at -1000 utility. In addition, the Taliban is offering a bounty to any soldier that deserts. ne soldier does not care about this, and would not take the bounty, while the other values the bounty at 50 utility. a. Draw the game based on this scenario. b. Find all pure strategy Nash equilibria c. Find the mixed strategy Nash equilibrium d. What does this game and the…
