In the real world, all of these variations are broadly covered by the concept of monopoly. The concern is that a monopoly will take advantage of its position to force consumers to pay prices that are higher than equilibrium. Many economists challenge the theoretical validity of general equilibrium economics because of the highly unrealistic assumptions made in perfect competition models.
Some of these criticisms also extend to its modern adaptation, dynamic stochastic general equilibrium. Milton Friedman , Joseph Schumpeter , Mark Hendrickson, and other economists have suggested that the only monopolies that cause market failure are government-protected.
A political or legal monopoly , on the other hand, can charge monopoly prices because the state has erected barriers against competition.
This form of monopoly was the basis of the mercantilist economic system in the 16th and 17th centuries. Modern examples of such monopolies exist to some extent in the utilities and education sectors.

Ultimately, the consumer can benefit from these innovations. If monopolies didn't make such huge amounts of money, then who would want to make the next revolutionary product?
Human beings are rational. It only makes sense to innovate and develop if there is an appropriate reward at the end of it. Why it is a market failure. Monopoly diagram and deadweight loss.

Save money. Neo-classical economic theory provides a model for us to examine the behavior of economic agents. Neo-classical economic theory was what you learned in "Econ ," and what you applied in your courses in "Environmental Economics. Conditions for a Perfectly Competitive Market. Neo-classical economic theory maintains that certain conditions should exist in order for a market economy to be an efficient allocator of resources.
When these conditions exist, this constitutes what is called the so-called "perfectly--or purely--competitive market. The theory maintains that market economy best provides what the people want, in the amounts demanded and at the lowest cost.
A perfectly competitive market is defined as one in which "the impersonal forces of supply and demand, of prices and costs, determine and achieve the optimal allocation of resources and distribution of income; producers and consumers act in their own self-interest. In order to have perfectly competitive markets, a number of ideal conditions must exist. Among these ideal conditions are:.
No monopolies one seller or monopsonies one buyer who can single-handedly influence the market. Furthermore, each of the many economic agents acts in their own self-interest, in an atmosphere of anonymous rivalry, not animosity. Producers aim to max profits; consumers max satisfaction thru their consumption. In seeking their own self interest, the agents cause the market to allocate resources efficiently, thus improving the lot of all.
A classic quote: the "invisible hand" in Adam Smith's Wealth of Nations : "each person is led if by an invisible hand to promote an end which was no part of his intention I have never known much good done by those who affected to trade for the public good. Thus, if all other things about a product are equal except price, consumers are indifferent to any motivation other than prices. This forces efficiency because producers must try to produce at the lowest cost and offer goods for sale at the lowest price.
People are not influenced by non-price competition. Resources are employed at their highest and best use unemployment of resources is transient, rarely permanent. If the market no longer demands buggy whips, then the market will no longer produce them. All the buggy whip resources will gravitate to where the demand is perhaps for computers?
As wage rates fall in one area, qualified people tend to gravitate, on the margin, to where the higher salaries are. They make informed decisions from the head, not the heart.
They have knowledge of prices, costs, trends, expectations now and into the future. And everyone has the same knowledge available; no "Information asymmetries. Perfect competition provides a benchmark of economic performance. But if one or more of these conditions is severely violated, we are said to have "a market failure.
A great deal of effort by economists has gone into quantifying and analyzing the effects of market failure conditions and the effects on society. The general field of study is called "welfare economics. It has to do with the overall economic well-being of the people.
Five Instances of Market Failure. Public goods: Pure public goods are defined by 2 essential characteristics:. Nonexcludable - A good is said to be nonexcludable when individuals cannot reasonably be excluded from consuming it. There is asymmetric information — the monopolist may know more than the consumer and can exploit this knowledge to its own advantage.
Monopolies may be productively inefficient because there are no direct competitors a monopolist has no incentive to reduce average costs to a minimum, with the result that they are likely to be productively inefficient. Monopolies may also be allocatively inefficient — it is not necessary for the monopolist to set price equal to the marginal cost of supply.
Consumers cannot compare prices for a monopolist as there are no other close suppliers. This means that price can be set well above marginal cost. E ven accounting for the extra profits derived by a monopolist , which can be put back into the economy when profits are distributed to shareholders, there is a net loss of welfare to the community.
Welfare loss is the loss of community benefit, in terms of consumer and producer surplus, that occurs when a market is supplied by a monopolist rather than a large number of competitive firms. Monopolists may employ fewer people than in more competitive markets.
Employment is largely determined by output — the more output a firm produces the more labour it will require. As output is lower for a monopolist it can also be assumed that employment will also be lower.
If the firm exploits its monopoly power and grow large it can also exploit economies of large scale. This means that it can produce at low cost and pass these savings on to the consumer. However, there would be little incentive to do this and the savings made might be used to increase profits or raise barriers to entry for future rivals. Monopolists can also be dynamically efficient — once protected from competition monopolies may undertake product or process innovation to derive higher profits, and in so doing become dynamically efficient.
It can be argued that only firms with monopoly power will be in the position to be able to innovate effectively. Because of barriers to entry, a monopolist can protect its inventions and innovations from theft or copying. Natural monopolies include gas, rail and electricity supply.
