Session Overview
 |
So far, we have only analyzed one type of oligopoly. However, even when there are a small number of firms in a market, they can behave in a variety of different ways. We can compare the outcomes from these different types of competition to the competitive market. In this lecture, we learn more about different models of oligopoly. Bertrand price competition can be applied to pricing cereal. Image courtesy of ElCapitan on Flickr. |
Keywords: Cournot competition; cooperative competition; cartels; mergers; Bertrand competition.
