$11. Anne and Bruce would like to rent a movie, but they can't decide what kind of movie to get: Anne wants to rent a comedy, and Bruce wants to watch a drama. They decide to choose randomly by playing "Evens or Odds." On the count of three, each of them shows one or two fingers. If the sum is even, Anne wins and they rent the comedy; if the sum is odd, Bruce wins and they rent the drama. Each of them earns a payoff of 1 for winning and 0 for losing "Evens or Odds." (a) Draw the game table for "Evens or Odds." (b) Demonstrate that this game has no Nash equilibrium in pure strategies.

David wants to auction a painting, and there are two potential buyers. The value for eachbuyer is either 0 or 10, each value equally likely. Suppose he offers to sell the object for $6, and the two buyers simultaneously accept or reject. If exactly one buyer accepts, the object sold to that person for $6. If both accept, the object is allocated randomly to the buyers, also for $6. If neither accepts, the object is allocated randomly to the bidders for $0. (a) Identify the type space and strategy space for each buyer. (b) Show that there is an equilibrium in which buyers with value 10 always accept. (c) Show that there is an equilibrium in which buyers with value 10 always reject.
Consider the following sequential game. Wally first chooses L or H. Having observed Wally's choice, Elizabeth chooses between A and F. The payoffs are as follows. If Wally chose L and Elizabeth chose A, the payoffs are 30 to Wally and 20 to Elizabeth. If Wally chose L and Elizabeth F, the payoffs are 40 to Wally and 10 and to Elizabeth. If Wally decides to opt for H and Elizabeth A, the payoffs are 10 and 2 to Wally and Elizabeth, respectively. Finally, if Wally opts for H and Elizabeth F, the payoffs are 35 toWally and 5 to Elizabeth. What is the outcome in the subgame perfect equilibrium of this game? (L,F) (H,A) (H,F) and (L,F) (L,A) and (H,F) (H,F)
Consider the following game. There are two payers, Player 1 and Player 2. Player 1 chooses a row (10, 20, or 30), and Player 2 chooses a column (10/20/30). Payoffs are in the cells of the table, with those on the left going to Player 1 and those on the right going to player 2. For example, a payoff 100/200 would mean Player 1 receives 100 and Player 2 receives 200.What is [are] the Nash Equilibrium [Equilibria] of this game?A) (10/10) and (20/20)B) (30/30)C) (10/20) and (20/10)D) (20/20)E) (30/30)
In Las Vegas, roulette is played on a wheel with 38 slots, of which 18 are black, 18 are red, and 2 are green (zero and double-zero). Your friend impulsively takes all $361 out of his pocket and bets it on black, which pays 1 for 1. This means that if the ball lands on one of the 18 black slots, he ends up with $722, and if it doesn't, he ends up with nothing. Once the croupier releases the ball, your friend panics; it turns out that the $361 he bet was literally all the money he has. While he is risk-averse - his utility function is u(x) =, where x is his roulette payoff - you are effectively risk neutral over such small stakes. a. When the ball is still spinning, what is the expected profit for the casino? b. When the ball is still spinning, what is the expected value of your friend's wealth? c. When the ball is still spinning, what is your friend's certainty equivalent (i.e., how much money would he accept with certainty to walk away from his bet). Say you propose the following…

Sam and Sarah are thinking about getting married. However if either of them cheats on the other, they would get a payoff of 10, while the other person gets zero. If neither cheat, they stay with each other and get a payoff of 7 each and if both cheat, the relationship falls apart and each get a payoff of 1. What is the Nash equilibrium of this game? a. Cheat, Cheat b. Not cheat, Not cheat Sam cheats, Sarah doesn't Sarah cheats, Sam doesn't
Suppose that Jason and Chad each are thinking of opening up a diet coke stand on the fourth floor of this building. Suppose that potential customers are evenly spaced on a distance that is normalized to 1. Customers will buy a diet coke from whichever stand requires the least walking. If they are the same distance the customer will flip a coin. This is depicted below. 1/4 1/2 3/4 If Jason is currently at 3/4, what is Chad's best response? a. Just left of 3/4 b. 1/2 c. Just right of 3/4 d. Just left of 1/2
Consider a one-time game involving a penalty kick in football/soccer. There are two players: kicker and goalkeeper. The kicker has two possible actions: kick left or right. The goalkeeper also has two possible actions: guess left or right. The kicker and goalkeeper move simultaneously. If the kicker and goalkeeper choose the same direction, the goalkeeper "wins" and the payoffs are (0,1). If the kicker and goalkeeper choose different directions, the kicker wins and the payoffs are (1,0). (a) Is there a pure strategy equilibrium in this game? Explain. (b) Derive and explain the mixed strategy equilibrium for this game.
Problem 3. Val and Earl are at work on a very hot afternoon. There is a job waiting for them. It takes only one person to do the job. The one who does it must crawl through a mucky culvert to connect a pipe. Once the pipe is connected, they can both go to a comfortable tavern for a beer. The game tree is shown below, where at the terminal nodes, the top number is Val's payoff and the bottom number is Earl's payoff. Val Do it Stall V 5 E 10 Earl Do it Stall 9 Val 4 Do it Stall 38 Earl Do it Stall 7 Val Do it Stall Earl 110 Do it Leave it 5 0 X X At the beginning of play, Earl is working on another job, but Val could do the job and if he does it right away, they can both go out for beer. Val could choose to stall, waiting for Earl to come back. If Val decides to stall, then when Earl gets back, he could do the job, or he could stall. If Earl chooses to stall, Val could either do the job, or stall again, and so on... If Val and Earl both stall until Earl's final decision node at the end…
Two roommates John and Joe are playing a simultaneous game of cleaning the apartment. If neither of them clean, the apartment gets filthy and both get a utility of 2. If John cleans and Joe doesn’t, John gets a utility of 1 and Joe gets a utility of 4. If Joe cleans and John doesn’t, Joe gets a utility of 1 and John gets a utility of 4 and if both clean up the apartment, they each get a utility of 3.What is the Nash equilibrium of this game? Group of answer choices Joe cleans, John doesn’t John cleans, Joe doesn’t Both of them clean the apartment Neither of them clean the apartment
Consider the following story: Charlie finds two fifty-pence pieces on the floor. His friend Dylan is standing next to him when he finds them. Chris can offer Dylan nothing at all, one of the fifty-pence pieces, or both. Dylan observes the offer made by Charlie, and can either accept the offer (in which case they each receive the split specified by Charlie) or reject the offer.If he rejects the offer, each player gets nothing at all (because Charlie is embarassed and throws the moneyaway).(a) Formulate this interaction as an extensive-form game. To keep things simple, players’ payoff is equal to their monetary gain.(b) List all histories of the game. Split these into terminal and non-terminal histories.(c) What are the strategies available to Charlie? What are the strategies available to Dylan? Draw the strategic-form game.(d) Find the pure-strategy Nash equilibria of this game.(e) What do you think will happen?
