Suppose we have two ice cream sellers, Blue Cool Ice Cream and Red Mango Ice Cream, deciding where to locate along a 1 kilometer long linear beach. Beachgoers are uniformly spread out everywhere along the beach. They do not like walking, and they view the ice cream from the two sellers as homogenous goods. Because of this, they will always buy from the nearest seller. The sellers cannot choose their price, only the location.
A strategy for a player in this game is a distance between 0m and 1000m, which represents where the player will locate. For example, a distance of 0m is a strategy.
The payoffs are the percentages of the market that each seller captures (depending on their two strategies). For example, if Blue Cool chooses 0m and Red Mango chooses 1000m, their payoffs are 50% and 50%. If the two sellers locate at exactly the same spot, they share the market and get 50% each.
Suppose each player can only choose from 11 locations: 0m, 100m, 200m, 300m, 400m, 500m, 600m, 700m, 800m, 900m, 1000m. Is 0m a dominated strategy for Blue Cool?

- A small community has 10 people, each of whom has a wealth of $3,000. Each individual must choose whether to contribute $300 or $0 to the support of public entertainment for their community. The money value of the benefit that a person gets from this public entertainment is one half of the total amount of money contributed by all individuals in the community. This game has a Nash equilibrium in which 5 people contribute $300 and for public entertainment and 5 people contribute nothing. This game has a dominant strategy equilibrium in which nobody contributes anything for public entertainment. This game has no Nash equilibrium in pure strategies, but has a Nash equilibrium in mixed strategies. This game has a dominant strategy equilibrium in which all 10 citizens contribute $300 to support public entertainment. This game has two Nash equilibria, one in which everybody contributes $300 and one in which no- body contributes $300.arrow_forwardA Nash equilibrium is where one player maximizes his/her payoff and the other doesn’t is where each player maximizes his/her own payoff given the action of the other player is where both players are maximizing their total payoff is a unique prediction of the likely outcome of a gamearrow_forwardFelix and Jocelyn are arrested and charged with armed robbery. The police interview both suspects separately about their involvement in the crime. Each suspect has to make a decision. They can betray the other suspect by confessing that they both committed the crime, or they can cooperate with the other suspect by remaining silent. The table shows the sentences that Felix and Jocelyn will receive given their choices. Use the table to answer the question. What will be the dominant strategy outcome for Felix and Jocelyn? They both get 12 years. O They both get 10 years. Felix gets 5 years, and Jocelyn gets 15 years. Jocelyn gets 5 years, and Felix gets 15 years.

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...

They can choose between two options: going to a soccer game or watching a football game. Alice prefers football and Julia prefers the football game, but they both prefer being together over being apart. If they both choose to attend a soccer game then Julia receives a payoff of 2 and Alice a payoff of 1. If they both choose to attend a football game, then Julia receive a payoff of 1 and Alice a payoff of 2. If one chooses a football game and the other a soccer game then they both receive a payoff of O. The payout matrix below illustrates these payoffs. Which of the following statements are true: I. There is a dominant strategy II. A nash equilibrium exists where Alice attends a football game and Julia attends a soccer game III. A nash equilibrium exists where both friends attend a soccer game IV. Both attending a football game is a stable outcome. Alice Soccer Football Julia Soccer Football…arrow_forward
- Microsoft and a smaller rival often have to select from one of two competing technologies, A and B. The rival always prefers to select the same technology as Microsoft (because compatibility is important), while Microsoft always wants to select a different technology from its rival. If the two companies select different technologies, Microsoft's payoff is 2 units of utility, while the small rival suffers a loss of utility of 1. If the two companies select the same technology, Microsoft suffers a loss of utility of 1 while the rival gains 1 units of utility. Using the given information, fill in the payoffs for each cell in the matrix, assuming that each company chooses its technology simultaneously. Microsoft Technology A Technology B Microsoft Rival: Microsoft Technology A Rival: Rival Microsoft Rival: Microsoft Technology B Rival: True or False: There is an equilibrium for this game in pure strategies.

Both stores must choose whether to charge a high price ($30) or a low price (s13) for the new Miley Cyrus CD. These price strategies with corresponding profits are depicted in the payoff matrix to the right. Target's profits are in red and Wal-Mart's are in blue. Target Target's dominant strategy is to pick a price of S Price = $30 Price = $13 $7,000 $2.500 Price = $30 S7,000 $15,000 Wal - Mart $15.000 $5,000 Price = $13 $2,500 $5,000 Wal-Mart's dominant strategy is to pick a price of $ The new equilibrium market wage will be and the new equilibrium market employment level will be higher unchanged lower higher lower unchangedarrow_forwardIn the game shown below, Player 1 can move Up or Down, and Player 2 can move Left or Right. The players must move at the same time without knowledge of the other player’s move. The first payoff is for the row player (Player 1) and the second payoff is for the column player (Player 2). Solve each game using game theoretic logic. Player 2 Player 1 Left Right Up 7, 7 2, 9 Down 9, 2 1, 3arrow_forward
- In the accompanying game, firms 1 and 2 must independently decide whether to charge high or low prices.

If they vote in favor of a raise, then they lose some public support, costing them each$1,500 per year. The salary increase passes if two or more politicians vote in favor of it.

Cameron goes first, and the players take turns choosing either 1 or 2. In each turn, they add the new number to a running total. The player who brings the total to exactly 10 wins the game. a) If both Cameron and Luke play optimally, who will win the game? Does the game have a first-mover advantage or a second-mover advantage? b) Suppose the game is modified to ”Race to 11” (i.e, the player who reaches 11 first wins). Who will win the game if both players play their optimal strategies? What if the game is ”Race to 12”? Does the result change? c) Consider the general version of the game called ”Race to n,” where n is a positive integer greater than 0. What are the conditions on n such that the game has a first mover advantage? What are the conditions on n such that the game has a second mover advantage?arrow_forward
