Monopoly profit is an inflated level of profit due to the monopolistic practices of an enterprise.
[Bradley R. Chiller, "Essentials of Economics", New York: McGraw-Hill, Inc., 1991.]
Basic classical and neoclassical theory
Traditional economics state that in a competitive market, no firm can command elevated premiums for the price of goods and services as a result of sufficient competition. In contrast, insufficient competition can provide a producer with disproportionate pricing power. Withholding production to drive prices higher produces additional profit, which is called ''monopoly profits''.
[Roger LeRoy Miller, ''Intermediate Microeconomics: Theory Issues Applications'', Third Edition, New York: McGraw-Hill, Inc, 1982.]
According to
classical and
neoclassical economic thought, firms in a perfectly competitive market are price takers because no firm can charge a price that is different from the
equilibrium price
In economics, economic equilibrium is a situation in which the economic forces of supply and demand are balanced, meaning that economic variables will no longer change.
Market equilibrium in this case is a condition where a market price is esta ...
set within the entire industry's perfectly competitive market.
[Tirole, Jean, ''The Theory of Industrial Organization'', Cambridge, Massachusetts: The MIT Press, 1988.] Since a competitive market has many competing firms, a customer can buy
widgets from any of the competing firms.
[Edwin Mansfield, "Micro-Economics Theory and Applications, 3rd Edition", New York and London: W.W. Norton and Company, 1979.][John Black, ''Oxford Dictionary of Economics'', New York: Oxford University Press, 2003.] Because of this tight competition, competing firms in a market each have their own horizontal
demand curve
A demand curve is a graph depicting the inverse demand function, a relationship between the price of a certain commodity (the ''y''-axis) and the quantity of that commodity that is demanded at that price (the ''x''-axis). Demand curves can be us ...
that is fixed at a single price established by market equilibrium for the entire industry as a whole.
Each firm in a competitive market has buyers for its product as long as the firm charges "no more than" the single price.
Since firms cannot control the activities of other firms that produce the same widget sold within the market, a firm that charges a price that is higher than the industry's market equilibrium price would lose business; customers would respond by buying their widgets from other competing firms that charge the lower market equilibrium price,
which makes deviation from the market equilibrium price impossible.
Perfect competition is commonly characterized by an idealized situation in which all firms within the industry produce exact comparable goods that are
perfect substitutes.
With the exception of
commodity markets
A commodity market is a market that trades in the primary economic sector rather than manufactured products. The primary sector includes agricultural products, energy products, and metals. Soft commodities may be perishable and harvested, w ...
, this idealized situation does not typically exist in many actual markets,
but in many cases, there exist similar products that are
easily interchangeable because they are close
substitutes (for example, butter and margarine).
[Henderson, James M., and Richard E. Quandt, "Micro Economic Theory, A Mathematical Approach. 3rd Edition", New York: McGraw-Hill Book Company, 1980. Glenview, Illinois: Scott, Foresmand and Company, 1988.] A significant rise in a product's price tends to cause customers to switch from this good to a lower priced close substitute.
[Roger LeRoy Miller, "Intermediate Microeconomics Theory Issues Applications, Third Edition", New York: McGraw-Hill, Inc, 1982.
See Reference to "Price Elasticity" as it relates to "substitutability", as well as the "Marginal Rate of Technical Substitution"] In some cases, firms that produce differing but similar goods have similar production processes, which makes it relatively easy for one-good firms to
switch
In electrical engineering, a switch is an electrical component that can disconnect or connect the conducting path in an electrical circuit, interrupting the electric current or diverting it from one conductor to another. The most common type o ...
their manufacturing processes to produce a different but similar good.
This would be the case when the cost of changing the firm's manufacturing process to produce the similar good can be somewhat immaterial in relationship to the firm's overall profit and cost.
Since consumers tend to replace goods whose prices are high with cheaper close substitutes, and the existence of close substitutes whose manufacturing processes are similar allows a firm producing a low-priced good to easily switch over to producing the other higher priced good, the competition model accurately explains why the existence of different similar goods form competitive forces that deny any single firm the ability to establish a monopoly in their product.
This effect is observable in a high profit and production cost industry, such as the car industry, and other industries facing competition from imports.

By contrast, the lack of competition in a market ensures the firm (monopoly) has a downward sloping demand curve.
Although raising prices causes the monopoly to lose some business, some sales can be made at higher prices.
Although monopolists are constrained by consumer demand, they are not "price takers" because they can influence price through their production decisions.
The monopolist can either have a ''target level of output'' that will ensure the monopoly price as the given consumer demand in the industry's market reacts to the fixed and limited market supply, or it can set a fixed monopoly price at the onset and adjust

occur at the final output level chosen.
At each price, the firm must accept the level of output as determined by the market's consumer demand, and every output quantity is identified with a price that is determined by the market's consumer demand. The price and output are co-determined by consumer demand and the firm's
production cost structure.
A firm with monopoly power sets a monopoly price that maximizes the monopoly profit.
The most profitable price for the monopoly occurs when output level ensures the

,
economic agents form new firms in the industry to obtain at least a portion of the existing economic profit.
As new firms enter the industry, they increase the supply of the product available in the market, and they are forced to charge a lower price to entice consumers to buy the additional supply they are supplying as competition.
Since consumers flock toward the lowest price (in search of a bargain), older firms within the industry may lose their existing customers to the new firms entering the industry, and are forced to lower their prices to match the prices set by the new firms.
New firms continue to enter the industry until the price of the product is lowered to the point that it is the same as the average economic cost of producing the product, and economic profit disappears.
When this happens, economic agents outside of the industry find no advantage to entering the industry, supply of the product stops increasing, and the price charged for the product stabilizes.
Normally, a firm that introduces a brand new product can initially secure a monopoly for a short while.
At this stage, the initial price the consumer must pay for the product is high, and the demand for, as well as the availability of the product in the market, will be limited. As time passes, when the profitability of the product is well established, the number of firms that produce this product will increase until the available product supply becomes relatively large, and the product's price shrinks down to the level of the average economic cost of producing the product.
When this occurs, all monopoly associated with producing and selling the product disappears, and the initial monopoly turns into a (perfectly) competitive industry.
When consumers have complete information about the prices available in the market and the quality of the products sold by the various firms, there cannot be a persistent monopolistic situation in the absence of barriers to entry and collusion.
[Steven M. Sheffrin, "Rational Expectations", New York: Cambridge University Press, 1987. John Black, "Oxford Dictionary of Economics", New York: Oxford University Press, 2003.] Various barriers to entry include patent rights
and the monopolization of a natural resource needed to produce a product.

If firms in an industry collude they can also limit production to restrict supply, and ensure the price of the product remains high enough to ensure all of the firms in the industry achieve an economic profit.
If a government feels it is impractical to have a competitive market, it sometimes tries to regulate the monopoly by controlling the price the monopoly charges for its product.
The old AT&T monopoly, which existed before the courts
ordered its breakup and tried to force competition in the market, had to get government approval to raise its prices.
The government examined the monopoly's costs and determined if the monopoly should be allowed to raise its price; if the government felt that the cost did not justify a higher price, it rejected the monopoly's application. Although a regulated monopoly will not have a monopoly profit that is high as it would be in an unregulated situation, it still can have an economic profit that is still above what a competitive firm has in a truly competitive market.
