Question 1
A special kind of imperfectly competitive market that has only two firms is called
◦ a natural monopoly.
◦ an incidental monopoly.
◦ a dublet.
◦ a two-tier competitive structure.
◦ a duopoly.
Question 2
Consider the three largest cell-phone service providers in Canada - Bell, Telus, and Rogers. If we observe that all three companies increase their monthly service fees simultaneously, we might conclude that
◦ they are perfect competitors and they are unable to set the price.
◦ they are creating entry barriers to prevent entry by new firms.
◦ they are engaged in predatory pricing.
◦ these firms have monopolized the industry.
◦ there is tacit collusion among these firms.
