the oligopolists earn the highest profit by cooperating and behaving like a monopolist.

Explanation:

Oligopoly is a market structure where there are few number of firms and, none of the firms can prevent the others from having an influence. Oligopolies can be as a result of various kinds of collusion which has reduced competition and led to higher prices for the consumers.

With few sellers, oligopolists are usually aware of the deeds of the others. An oligopoly maximizes profit as they are price setters and barriers to entry are very high. The barriers to entry include patents, economies of scale, access to expensive technology, government licenses, and strategic actions by the firms designed to prevent new firms.

Oligopolies can therefore retain long run abnormal profits like a monopolist as the high barriers prevent firms from entering market to capture the excess profits.
