Chapter 13, Problem 7DQ

Suppose a single firm produces all of the output in a contestable market. The market inverse demand function is P = 250 -4Q, and the firm’s cost function is C(Q) = 8Q. Determine the firm’s equilibrium price and corresponding profits.Price: $    Profits: $

Suppose a single firm produces all of the output in a contestable market. Analysts determine that the market inverse demand function is P = 200 -2Q, and the firm’s cost function is C(Q) = 8Q. Determine the firm’s equilibrium price and corresponding profits.   Price: $   Profits: $

Suppose a single firm produces all of the output in a contestable market. Analysts determine that the market inverse demand function is P = 400 -4Q, and the firm’s cost function is C(Q) = 16Q. Determine the firm’s equilibrium price and corresponding profits.Price: $   Profits: $

The four-firm concentration ratios for industries X and Y are 81 percent and 74 percent, respectively, while the corresponding Herfindahl-Hirschman indexes are 3,100 and 1,600. The Dansby-Willig performance index for industry X is 0.7, while that for industry Y is 0.55. Based on this information, which would lead to the greater increase in social welfare: a slight increase in industry X’s output or a slight increase in industry Y’s output?

Choose the most appropriate answer. 1.1 Read the following extract and answer question 1.1, 1.2. Evidence of dominationBoth the Competition Commission and Icasa found, in their inquiries, that Vodacom and MTN are dominantacross the supply chain. Their dominance is even more entrenched by the spectrum-sharing deals that they haveentered into with Cell C, Liquid Intelligent Technologies and Rain. Cell C is wholly reliant on MTN and Vodacomto provide mobile services, and Liquid and Rain are disincentivised from competing aggressively in the mobilemarket due to the lucrative deals they have struck to provide capacity to either Vodacom or MTN, or both. Thishas limited their ability to compete independently – leaving Telkom as the only entity in the position to be able tochallenge the “cosy” market structure head-on.Source: https://techcentral.co.za/mcleod-is-wrong-about-telkom/110373/Accessed: 19/08/21 The economic argument being expressed in this extract is that of __________ and has the…
