Ma3.
You operate in a duopoly in which you and a rival must simultaneously decide what price to charge for the same homogeneous product. Assume each you and your rival can choose a “low price” or a “high price”. If you each charge a low price, you each earn zero profits. If you each charge a high price, you each earn profits of $3 million. If you charge different prices, the one charging the high price loses $5 million and the one charging the low price makes $5 million.
What is the Nash equilibrium for the non-repeated version of this game?
Now suppose the game is infinitely repeated. If the interest rate is 10%, can you do better than you could in the non-repeated version of this game? If your answer is “yes”, provide the players’ strategies and any other conditions that must hold.
Question 2 [JP.14.3.19]
Consider a duopoly where the market demand is described by the equation: P = 150- Q. The marginal
cost for each firm is $60.
lo.] If the firms compete simultaneously with output, what is each firm's profit-maximizing output, the market
quantity, and the price each firm charges?
(b.) What is the economic profit eamed by each firm (from question [a]}
[c.) If Firm 1 is a leader in output, what is each firm's profit-maximizing output, the market quantity, and the
price each firm charges?
[d.] What is the economic profit earned by each firm (from question [c])?
Consider an oligopolistic market with 5 identical firms that choose their profit-maximizing quantities simultaneously. Suppose each firm has constant
marginal costs of $123 per unit and the market elasticity of demand is - 1.08.
What is the change in the prevailing market price if one additional firm joins the market? Assume that the potential entrant is identical to the incumbent
firms.

- What did Harvard economist Edward Chamberlin say about the observation that a monopolistically competitive firm's average cost of production exceeds its minimum average total cost? Select one: O a. Chamberlin argued that this belief is incorrect. In his view, monopolistically competitive firms do not produce at a cost above their minimum average total costs. O b. Chamberlin argued that these higher costs represent the wastefulness of this market structure. O c. In Chamberlin's view, this is evidence that monopolistic competition uses society's resources inefficiently and in a fashion that merits government intervention. O d. According to Chamberlin, this cost difference represents the value consumers place on variety and having more choice.arrow_forwardThe graph below shows a duopolistic market.

- Which of the following most accurately explains a general distinction between oligopolists that advertise and those that do not? O Unlike nonadvertising oligopolists, advertising ones allocate resources inefficiently, charge a higher price, and restrict output so that price exceeds average cost. O Advertising oligopolists decrease the price to increase sales, whereas nonadvertising ones increase prices to increase profits. O Advertising oligopolists compete using product differentiation instead of price reductions, whereas nonadvertising firms collude to form a cartel to maximize joint profits. O Advertising oligopolists set prices and output quotas to maximize joint profits, whereas nonadvertising ones use product differentiation.arrow_forwardQuestion 2 AnimoSpace Support ?
