Let ci be the constant marginal and average cost for firm i (so that firms may have different marginal costs). Suppose demand is given by P=1-Q. Calculate the Nash equilibrium quantities assuming there are two firms in a Cournot market. Also compute market output, market price, firm profits, industry prof- its, consumer surplus, and total welfare. Represent the Nash equilibrium on a best-response function diagram. Show how a reduction in firm 1’s cost would change the equilibrium. Draw a representative isoprofit for firm 1.
O Macmillan Learning McLaren and Red Bull are competing for the Formula One Constructors' Championship and are deciding whether to increase their spending on their aerodynamic (aero) development. The matrix displays the payoffs to the team that result from each possible choice. Note that, due to other factors, the payoffs are not symmetrical. Assume that each team's goal is to earn as many points as possible. a. Does McLaren have a dominant strategy? If so, what is it? O Yes. Their dominant strategy is to leave aero development spending unchanged. O Yes. Their dominant strategy is to increase aero development spending. O No, they do not have a dominant strategy. b. Does Red Bull have a dominant strategy? If so, what is it? O Yes. Their dominant strategy is to increase aero development spending. Yes. Their dominant strategy is to leave aero Red Bull Raise spending Do not change spending McLaren Increase spending Do not change spending McLaren earns 142 points McLaren earns 360 points…
Which of the following accurately describes a player's strictly dominant strategy? O It is a strategy that is better than all the player's other strategies, no matter what the other players do. There is always at least one player who has one in every game.. O It is the strategy a player uses in the Nash equilibrium of a game. Since a Nash equilibrium always exists, players always have a strictly dominant strategy. O It is a strategy that is better than all the player's other strategies, no matter what the other players do. A player may or may not have one. O It is a strategy that is better than all the player's other strategies, no matter what the other players do. Every player has a dominant strategy in every game.. O It is the strategy a player uses in the Nash equilibrium of a game. Since a Nash equilibrium may not exist, players may not always have a strictly dominant strategy.
5. To advertise or not to advertise Suppose that Expresso and Beantown are the only two firms that sell coffee. The following payoff matrix shows the profit (in millions of dollars) each company will earn depending on whether or not it advertises: Beantown Advertise Doesn't Advertise Advertise 9, 9 15, 3 Expresso Doesn't Advertise 3, 15 11, 11 For example, the upper right cell shows that if Expresso advertises and Beantown doesn't advertise, Expresso will make a profit of $15 million, and Beantown will make a profit of $3 million. Assume this is a simultaneous game and that Expresso and Beantown are both profit-maximizing firms. If Expresso decides to advertise, it will earn a profit of $ million if Beantown advertises and a profit of $ million if Beantown does not advertise. If Expresso decides not to advertise, it will earn a profit of $ million if Beantown advertises and a profit of $ million if Beantown does not advertise. If Beantown advertises, Expresso makes a higher profit if…
in this game table, Pepsi's payout is on the left and Sam's Choice's is on the ight. Is the Nash equilibrium a prisoner's dilemma? Pepsi High Low Sam's Choice High 110, 20 60, 10 Low 80, 40 70, 30 O No, it is not because both firms played their dominant strategies. O Yes, it is because the combined payoff for the two firms is lower than another outcome. O Yes, it is because at least one of the firms ends up with the lowest possible payoff. O No, it is not because at least one firm has achieved its highest possible payoff.
Little Kona is a small coffee company that is considering entering a market dominated by Big Brew. Each company's profit depends on whether Little Kona enters and whether Big Brew sets a high price or a low price: Little Kona True True or False: Only Little Kona has a dominant strategy in this game. False Big Brew High Price Low Price Enter $2 million, $3 million $2 million, $1 million Don't Enter 50, 58 million $0, $3 million Which of the following outcomes represent a Nash equilibrium in this case? Check all that apply. Big Brew maintains a high price and Little Kona does not enter. Big Brew maintains a low price and Little Kona does not enter.

Big Brew threatens Little Kona by saying, "If you enter, we're going to set a low price, so you had better stay out." Thin True or False: Little Kona should believe the threat.
