Problems:<br />

1. Because there are only a few firms in an oligopoly market, each firm produces a significant<br />

quantity of output. Thus, each firm’s production decision affects market price, and the other<br />

firms in the industry. This is mutual interdependence. Each firm’s actions affect the other firms.<br />

2. Even if a cartel is legal, it will prove difficult to maintain because of:<br />

(1) Noncartel competition<br />

(2) The tendency of cartel members to “cheat” on the agreement<br />
