In the previous lectures, we began to learn about firms' decisions in a competitive market where there are a large number of firms. However, different markets have different characteristics, and in some markets there may be only one or a few firms. In this lecture, we begin to learn about the operations of a monopoly market, where only one firm is producing a given good.
The game Monopoly is named after the economic concept, in which one firm dominates an entire market. Image courtesy of William Boncher on Flickr.
Keywords: Monopoly; marginal revenue; marginal cost; profit maximization; shutdown rule; market power; price discrimination.
