Lets again consider the same two firms from the previous question. In this game, both firms have already entered the market and now decide what price to charge. For concreteness, suppose that there are 10 million customers, each of whom will buyfrom one of the two firms, and that each firm decides whether to charge $20 or $30 (with costs of zero). If both firms charge the same price, they will each sell to 5 million customers, but if one charges the low price ($20) and the other charges the highprice ($30), 8 million will buy from the low-price firm and 2 million will buy from the high-price firm.(a) Create a payoff matrix for this game.(b) Identify any dominant strategies for either of the two players.(C) Identify any Nash equilibrium in the game, using the best response analysis.(d) Is this a Prisoner's Dilemma situation?

Suppose Carlos and Deborah are playing a game in which both must simultaneously choose the action Left or Right. The payoff matrix that follows shows the payoff each person will earn as a function of both of their choices. For example, the lower-right cell shows that if Carlos chooses Right and Deborah chooses Right, Carlos will receive a payoff of 6 and Deborah will receive a payoff of 5. Deborah Left Right Carlos Left 8, 4 4, 5 Right 5, 4 6, 5 The only dominant strategy in this game is for to choose . The outcome reflecting the unique Nash equilibrium in this game is as follows: Carlos chooses and Deborah chooses .
Untied and Air ’R’ Us are the only two airlines operating flights between Collegeville and Bigtown. Each airline can charge either a high price or a low price for a ticket. The accompanying matrix shows their payoffs, in profits per seat (in dollars), for any choice that the two airlines can make. Suppose the two airlines play a one-shot game—that is, they interact only once and never again. What will be the Nash (noncooperative) equilibrium in this one-shot game? Explain why this is the likely outcome. Now suppose the two airlines play this game twice. Each airline then considers the future and decides on a “tit-for-tat” strategy, that is, it starts off charging the high price in the first period, and then in the second period it does whatever the other airline did in the previous period. If both play this…
Solving for dominant strategies and the Nash equilibrium Suppose Felix and Janet are playing a game in which both must simultaneously choose the action Left or Right. The payoff matrix that follows shows the payoff each person will earn as a function of both of their choices. For example, the lower-right cell shows that if Felix chooses Right and Janet chooses Right, Felix will receive a payoff of 3 and Janet will receive a payoff of 7. Attached the table The only dominant strategy in this game is for (Janet / Felix) to choose (Left / Right). The outcome reflecting the unique Nash equilibrium in this game is as follows: Felix chooses (Left / Right) and Janet chooses (Left / Right).
Suppose that two players are playing the following game. Player 1 can choose either Top or Bottom, and Player 2 can choose either Left or Right. The payoffs are given in the following table: Player 1 Player 2 Left Right Top 6 1 9 4 Bottom 2 4 5 3 where the number on the left is the payoff to Player 1, and the number on the right is the payoff to Player 2. D) What is Player 1’s maximin strategy?E) What is Player 2’s maximin strategy?F) If the game were played with Player 1 moving first and Player 2 moving second, using the backward induction method we went over in class, what strategy will each player choose?
Imagine that there are two snowboard manufacturers (FatSki and WideBoard) in the market. Each firm can either produce ten or twenty snowboards per day. The table below (see attached) shows the profit per snowboard for each firm that will result given the joint production decisions of these two firms. Draw the game payoff matrix for this situation. Does either player have a dominant strategy? If so, what is it? What is the Nash equilibrium solution and how many boards should each player produce each day? Since FatSki and WideBoard must play this game repeatedly (i.e. make production decisions every day), what strategy would you advise them to play in order to maximize their payoff over the long term?
Suppose there are only two firms that sell smartphones, Flashfone and Pictech. The payoff matrix that follows shows the profit (in millions of dollars) each company will earn, depending on whether it sets a high or low price for its phones. For example, the lower-left cell shows that if Flashfone prices low and Pictech prices high, Flashfone will earn a profit of $6 million and Pictech will earn a profit of $1 million. Assume this is a simultaneous game and that Flashfone and Pictech are both profit-maximizing firms.
Alice and Betsy are playing a game in which each can play either of two strategies, leave or stay. If both play the strategy leave, then each gets a payoff of $400. If both play the strategy stay, then each gets a payoff of $800. If one plays stay and the other plays leave, then the one who plays stay gets a payoff of $C and the one who plays leave gets a payoff of $D. When is the outcome where both play leave a Nash equilibrium? a) never, since 800 > 400 b) when 400 > C and D > 800 but not when 800 > D c) whenever 400 > C d) when D > C and C > 400 e) whenever d < 800
Suppose Carlos and Deborah are playing a game in which both must simultaneously choose the action Left or Right. The payoff matrix that follows shows the payoff each person will earn as a function of both of their choices. For example, the lower-right cell shows that if Carlos chooses Right and Deborah chooses Right, Carlos will receive a payoff of 7 and Deborah will receive a payoff of 6. The only dominant strategy in this game is for ____ to choose ____ . The outcome reflecting the unique Nash equilibrium in this game is as follows: Carlos chooses ____ and Deborah chooses ____ .
Two firms A and B compete on price. They can choose a low or high price. Firm A is smaller than firm B, and typically earn a lower payoff. For instance if both firms offer a low price firm A earns $400, and B $500, and if they both offer a high price Firm A earns just $400, while firm B earns $1,000. However, when Firm A offers a low price and B a high price firm A can gain an advantage and will earn $600, while B will earn $400. Finally, if the situation is reversed and B offers a low price and B a high price, B will steal the market and earn $1,500 while A will earn nothing. Please construct a payoff matrix for this situation Does Firm A have a dominant strategy?
Consider the following game, called matching pennies, which you are playing with a friend. Each of you has a penny hidden in your hand, facing either heads up or tails up. You know which way the penny is facing in your own hand. On the count of three, you simultaneously show your pennies to each other. If the face-up side of your coin matches your friends, you get to keep both pennies. If they do not match, your friend gets to keep both. a. Who are the players in this game? What are each player’s strategies? b. Construct a payoff matrix for this game. c. Does either player have a dominant strategy? Explain d. Is there a Nash equilibrium? Explain.
For the questions that ask you to draw the games, you can either draw them on the computer, or draw them by hand and then insert a picture. The table function in word works well for drawing these games, and was what I used. Part 1: Dominant and dominated strategies In the following games, identify any dominant or dominated strategies. Specify whether the strategy is strictly or weakly dominant/dominated. Then use dominant and/or dominated strategies to provide the solution to the game. Player 2 Player 1 Left Right Up 4, 1 2, 4 Down 1, 2 3, 3 Player 2 Player 1 Left Center Right Up 7, 3 8, 6 4, 9 Middle 1, 8 5, 7 3, 4 Down 2, 1 9, 5 6, 2 Player 2 Player 1 Left Center Right Up 2, 1 3, 6 7, 5 Middle 0, 8 7, 7 3, 5 Down 2, 2 4, 1 3, 1 Assume there is some deadly airborne disease.
