- Two firms operating in the same market must decide between charging a high price or a low price. The Payoffs are as below. Firm A's profit is listed before the comma, B's profit after the comma. Firm B Firm A Low Price High Price Low Price 16, 17 7, 28 High Price 28, 7 22, 22 If each firm tries to choose a price that is optimal, regardless of the other firm's price, what is the Nash equilibrium? Does either firm have a dominant strategy?prove that the following strategy profile is a Nash equilibrium:For any 0 < x ≤1, player 1 offers x to player 2, player 2 accepts any offer greater than orequal to x and rejects any offer smaller than x.Is this strategy profile a subgame perfect equilibrium as well? Briefly explain why.Imagine a small town with three car repair shops competing for a limited number of customers. Explain why the three shops working together to keep their prices high is unlikely to be a Nash equilibrium.
- What is game theory? How does it relate to strategic decision making? What do the phrases dominant strategy and Nash Equilibrium mean as they apply to game theory?The town of Grayling has 10 thousand residents who produce fish from fish farms and lakes. Each person who works on a fish farm produces 2 fish per day. Each person who fishes in a lake produces 10-X fish per day where X is the number of people (in thousands) who fish in the lakes. If every individual who fishes a lake is charged a tax of T fish, what value of T causes the Nash Equilibrium behavior to produce the largest possible number of fish for the town as a whole? (You can assume that the 'taxes' collected are shared among all of the residents)Mr. and Mrs. Ward typically vote oppositely in elections and so their votes "cancel each other out." They each gain 24 units of utility from a vote for their positions (and lose 24 units of utility from a vote against their positions). However, the bother of actually voting costs each 12 units of utility. The following matrix summarizes the strategies for both Mr. Ward and Mrs. Ward. Mr. Ward Vote Vote Mrs. Ward Mr. Ward: -12, Mrs. Ward: -12 Don't Vote Mr. Ward: -24, Mrs. Ward: 12 The Nash equilibrium for this game is for Mr. Ward to payoff of Don't Vote Mr. Ward: 12, Mrs. Ward: -24 Mr. Ward: 0, Mrs. Ward: 0 units of utility and Mrs. Ward receives a payoff of and for Mrs. Ward to units of utility. Under this outcome, Mr. Ward receives a
- Which of the following best describes Nash equilibrium? a) A situation where one player dominates the others b) A situation where each player's strategy is optimal given the strategies of the others c) A situation where all players cooperate perfectly d) A situation where players change strategies constantlyIn a game of chicken, two drivers are heading towards each other on a collision course. The first one to swerve is considered the "chicken" and loses. What is the Nash equilibrium in this game? a) Both drivers swerve b) Neither driver swerves c) One driver swerves while the other doesn't d) It depends on the specificConsider the following simultaneous games. List all pure equilibrium.
- There is a city, which looks like chopped isosceles triangle, as shown below. Citizens live uniformly distributed all over the city. Two ice-cream vendors, A and B, must independently set up stores in the city. Each citizen buys from the vendor closest to their location and when equidistant from both vendors they choose by coin toss. Each vendor’s aim is to maximize the expected number of customers. A choice of location by the two vendors is a Nash equilibrium if no vendor can do better by deviating unilaterally. Does this game have a Nash equilibrium? If so, describe it. If not, explain why notTwo 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.You suspect that you are a price leader in the market. Moreover, you are considering expanding your operations. H.R. Shovenstuff will observe your moves and then follow, but he is more secretive so you will not know whether to price high or low after his pricing decision has been made. Using the following game tree, solve for the Nash equilibrium. High Price Shovenstuff High Price Low Price You High Price (2,1) (6,2) Invest Low Price Invest, High Price, High Price O Invest, Low Price, High Price Invest, Low Price, Low Price O Don't Invest, High Price, High Price Don't Invest, Low Price, High Price LOW Price (2,4) You High Price (4,4) Don't Invest High Price Low Price Shovenstuff Low Price You High Price (8,1) (2.6) Low Price (2,1)
