Because there is a small number of large firms, these need to take careful notice of each other`s actions. This may lead to firms tocollude avoiding unexpected outcomes, maximizing industry profits. However, there is strong price rigidity where prices tend to change much less than in more competitive markets.
Collusive andNon-collusive Oligopoly
Collusive oligopoly: exists when the firms in an oligopolistic market collude to charge the same prices for their products, acting as a monopoly. Try to keep prices stable in orderfor the situation of monopoly will remain.
