Monopoly Diragram

A monopoly is a profit maximising firm that produces at MC = MR. A monopoly is able to profit maximise in the short- run and long-run due to the high barriers to entry within the industry.

 

Benefits of Monopolies

Economies of scale

A monopoly can benefit from economies of scale. This allows the monopoly to become more efficient and earn more profits. In some cases monopolies will also pass on costs reductions to consumers by lowering prices.

Investment

A monopoly earns enough profits to allow it to reinvest a percentage of its profits to become more efficient.

Research & Development

Large firms are able to spend money on research and development for a long period of time.

Innovation

A monopoly has the knowledge, expertise and finance to innovate successfully.

Disadvantages of Monopolies

Less choice for consumers

A monopoly dominates the market leaving consumers with less choice due to a lack of competition.

Higher prices

A lack of competition with high barriers to entry allows firms to charge high prices to maximise profits.

X-inefficient

Due to a lack of competition monopolies can become inefficient. They have no incentive to become efficient as they will still have consumer demand.

Other forms of Monopoly

Pure Monopoly

A pure monopoly exists when only one firm exits in the market.

Duopoly

A duopoly exists when two firms dominate the market.
