1. Many people consider political advertising (campaign advertisements) to be a classic example of a prisoners' dilemma. (a) Using examples from a recent political campaign with which you are familiar, explain whether this is the case. Write down an example payoff matrix for this case. 2. Answer all parts of this question. (a) Find all allocations that are Pareto efficient in the Prisoners' dilemma game. Does moving from an allocation where both players defect to an allocation where one defects and the other cooperate feature a Pareto improvement?

5. The Stag Hunt is a famous coordination game where two hunters must work together to hunt a stag but each one has the option to go solo and hunt a hare. The following payoff matrix depicts such a game: a. b. Hunter A Stag Hare Stag 5,5 4,0 Hunter B Hare 0,4 4,4 List any pure strategy Nash equilibria if they exist. Does the game have a mixed strategy Nash equilibrium? If so, solve for it.
Describe the Nash equilibrium/a and the mutually-preferred outcome. Finally, consider how people are sometimes able to resolve this social dilemma in the real world. Clearly explain how this method is successful in moving the players to a socially optimal outcome.
Question 2. Two students are working together to submit their Microeconomics mid-semester group coursework. Each student i can put in the effort x; that costs c(x;), in which x; E [0, 1]. This gives each student the utility of u(x1, x2). Formu- late this situation as a strategic game.
rituo? A. Identify the pure-strategy Nash equilibrium/a in the game below, and identify the Pareto efficient strategy combinations. (You may simply state these, you do not need to show how you derived your answer.) B. Identify the mixed-strategy equilibrium to the game. Show your work. You may use the equations from the "generic" 2X2 game if you wish. Doing it the long way is fine, however. C. State the payoff for each player in the mixed-strategy equilibrium. Is the mixed-strategy combination Pareto efficient? Player 1 U D 20 Player 2 L (10,15) (1,5) R (0,6) (1,6)

John and Jane usually vote against each other’s party in the SSC elections resulting to negating or offsetting their votes. If they vote for their party of choice, each of them gains four units of utility (and lose four units of utility from a vote against their party of choice). However, it costs each of them two units of utility for the hassle of actually voting during the SSC elections. A. Diagram a game in which John and Jane choose whether to vote or not to vote.

Two supermarkets face the following possibilities. Superstore Advertise Don’t Advertise Megastore Advertise $95, $80 $305, $55 Don’t Advertise $65, $285 $165, $115 47. A Nash equilibrium is Group of answer choices for Megastore to advertise and for Superstore to advertise. for Megastore to advertise and for Superstore not to advertise for Megastore not to advertise and for Superstore to advertise. for Megastore not to advertise and for Superstore not to advertise. There is no Nas equilibrium in this rivalry game.
1. Consider a game of chicken: two players approach a narrow bridge with room only for one, and each chooses either to go through and hope the other guy backs off (call this action H, for "hawk"), or backs off to let the other go through (call this action D, for "dove"). If both players are normal, then each gets a payoff of -1 from a collision (i.e. if both choose H), 1 if they choose H against D, 0 if they choose D (regardless of what the other player chooses). Now perturb the game as follows: there is a chance p > 0 that P2 is a “violent type", who gets 1 from playing H regardless of Pl's action, and -1 from playing D, again regardless of P1's action. (a) Illustrate the game tree corresponding to the Harsanyi transformation of this game (i.e. the dynamic game of imperfect information in which nature moves first). (b) Illustrate the extended game (i.e. the normal form game corresponding to your game tree in part (a)). (c) Find all values of p for which there is a BNE in which P1…

However, it costs each of them two units of utility for the hassle of actually voting during the SSC elections. A. Diagram a game in which John and Jane choose whether to vote or not to vote. B. Suppose John and Jane is in agreement not to vote during the election. 1.) Would such an agreement improve utility? Justify your answer. 2.) Would such an agreement be an equilibrium? Justify your answer.
