Monopolies, are they all bad?

The term monopoly carries many bad connotations, but are they all bad?

Next time you get a bus during the middle of the day in Dublin, be thankful for monopolies. Dublin Bus are a government sanctioned monopoly. Having the monopoly means no competition, which can be bad, but the Government can ensure that the monopolist provide certain services which the Government deem socially beneficial which include providing bus services on routes and at times which are non profit making. In general monopolies do not produce at the lowest point on their average cost curve and are not as efficient as they could be if they were in a competitive market.

How and why do monopolies exist?

There are a number of ways for monopolies to exist, each of the following types of monopoly have sufficient barriers to entry such that no firm can successfully enter the market and compete in a meaningful way.
We already saw Government sanctioned. The government provide one license to one company (Government run or not) to provide a service, they do not allow another service provider.

If a company have total control of a primary resource which is used in the production of a good, they can monopolize the market by being the sole producer. This is also true if a company hold a Patent or Copyright on a good or service, this is a legal document allowing no company to provide the same product or service, this is to protect a companies investment in research and development.

If a company is sufficiently large it can keep others out of the market due to Economies of Scale, as they can make it impossible to compete with them without a huge investment beyond the capability of any competing organisation. If a company has Technological Superiority or skills that are not possible to match or recreate, they can make it impossible to compete with them, in a similar way to the way Barcelona play football, many can try and copy their style but without players like Messi, Iniesta, Xavi and Fabregas, it is not possible to do it with the same success.

Can Monopolists charge what they want and sell as many as they like?

Monopolists can charge as much as they want or they can set the number of goods they will make available for sale, but they cannot do both. If a monopolists sets a price, then they hand control over to the market to decide how many items they will sell. The same is true when the monopolists sets the quantity available, they will sell this quantity at the price set by the market.

Disadvantages of Monopolies

• Monopolists normally do not produce at the lowest point of AC, so they are potentially wasteful.
• Monopolies earning S N P show that consumers are being exploited. 
• No choice of products/services. 
• Lazy suppliers, no incentive to be innovative as consumers have no choice. 
• Monopolists can sometimes be inefficient as they control price or quantity supplied.
• Monopolists can practice price discrimination and further exploit customers
