Session Overview

We have already learned about the operation of two very different types of markets: perfectly competitive markets and monopolists. However, most markets don’t fall into either category. For example, think of the market for soda - both Pepsi and Coke are major producers, and they dominate the market. This type of market structure is known as an oligopoly, and it is the subject of this lecture.
