Instructor: Sean Kennedy

Depending on the industry a company enters into, it may face - or be - a monopoly. In this lesson, we will compare the characteristics of a monopoly, oligopoly, and monopolistic competition, and provide examples.

Types of Monopolies

Have you ever wondered why a company doesn't just enter into a market with little to no competition? Unfortunately, it is not that easy. Various industries operate with different levels of competition. The decisions a company makes often have to do with the amount of competition it has. Being competitive is essential to being successful. When operating a business, it is critical to know how many competitors you have, and how your industry works. For instance, if you want to get into the liquor industry it would be essential to know there is a lot of competition, and the pricing of your products has to align with competitors' pricing. If you were to operate in a niche market or vertical market, there is less competition involved because it is a specialized product or service.


If you want your business to have complete control over the market, you would want to have a monopoly. A monopoly has pricing power in the market and no competition because of a high barrier to entry. When there is a high barrier to entry, there are high start-up costs or other obstacles that make it more difficult for competitors to enter into the market.

A monopoly can charge others high prices because there are no other companies offering similar products or services. I know, you are thinking how fair is that? It's not very fair, but unfortunately, companies often have no choice but to get products from a monopolistic company. Depending on the industry there could be regulations to help control a monopoly's pricing of products.

Let's say Joe moves to a new neighborhood. He wants cable but there's only one cable company serving the area. It's a monopoly because it sets the price to be whatever it wants; there is no competition because a new business would have to set up all that infrastructure first (high cost of entry). While the cable company may charge high prices, Joe has no other option if he want to receive multiple channels.


A oligopoly is a market that has few suppliers, and the companies that operate in it face little competition because of the high barriers to entry. Unlike a monopoly, these companies do not have complete control over their pricing. They have to keep track of competitors' pricing and adjust their prices accordingly. The fixed costs for entering into the industry are high which is why it's hard for companies to come into the market and be successful.

Joe wants to set up landline phone service; there are only three companies to pick from. This is an oligopoly because there's some competition among them, but not a lot. It's easier for a new company to enter the market in this case because there's a lower barrier to entry; most homes are already wired for landline phone service, so some of that infrastructure is already there.
