Question

Use the following scenario to answer the following questions:

In 2011, three firms (Firm A, Firm B, and Firm C) were selling cellular phone service for a price of $40 per month in Playa del Carmen, Mexico. Each firm serviced 100 cell phone customers; thus, all firms together serviced a total of 300 customers. Assume marginal cost is $0 (zero) for all firms and thus total revenue is equal to total profit. In 2012, Firms A and B each continued to service 100 customers, but Firm C now serviced 150 customers; thus, all firms together serviced a total of 350 customers. All firms now charge $30 per month.

Assume that there is an oligopoly consisting of firms of different sizes. If a small firm increases output by 25 percent, the price effect realized by the small firm will be ________. If a large firm increases output by 25 percent, the price effect realized by the large firm will be ________.
