- Consider a perfectly competitive market that was in a long-run equilibrium when a permanent increase in demand occurs. Which of the following will occur as a result? i. The existing firms will start to earn an economic profit. ii. New firms will be motivated to enter the market. iii. Some firms that cannot meet the new demand will exit the market. A) i and ii only B) ii and ii only C) i and iii D) ii only E) i, ii and iiIn perfect competition, why is a firm's marginal revenue curve also the demand curve for the firm's output?

Show Transcribed Text 3 Scenario 16-7 Consider the problem facing two firms, Yum Yum and Bertollini, in the frozen food market. Each firm has just come up with an idea for a new "frozen meal for two" which it would sell for $9. Assume that the marginal cost for each new product is a constant S2, and the only fixed cost is for advertising. Each company knows that if it spends $12 million on advertising it will get 1.5 million consumers to try its new product. Yum Yum has done market research which suggests that its product does not have any "staying" power in the market. Even though it could get 1.5 million consumers to buy the product once, it is unlikely that they will continue to buy the product in the future. Bertollini's market…13.
