Oligopoly Question, help!?

Question

can collusion be sustained in the long run in an oligopolist market?

Answer 1

There are several factors involved here, including each firm's ability to commit to the oligopolistic agreement, their patience (future discounting factor), and, ultimately, their number. In fact, the more firms, the less likely the collusion to sustain. If you simply need a "yes" or "no" answer, then "yes", under proper conditions it may be sustained.
