Competition (Encyclopedia of Psychology)
An adaptive strategy that pits one person's interests against another's.
Psychologists have long been in disagreement as to whether competition is a learned or a genetic component of human behavior. Perhaps what first comes to mind when thinking of competition is athletics. It would be a mistake, however, not to recognize the effect competition has in the areas of academics, work, and many other areas of contemporary life. This is especially true in the United States, where individual rigor and competition appear to be nationalistic qualities Americans cherish and praise. It has often been suggested that the American capitalist-driven society thrives because of the spirited competition for a limited amount of resources available.
Psychologically speaking, competition has been seen as an inevitable consequence of the psychoanalytic view of human drives and is a natural state of being. According to Sigmund Freud, humans are born screaming for attention and full of organic drives for fulfillment in various areas. Initially, according to this view, we compete for the attention of our parentseeking to attract it either from siblings or from the other parent. Thereafter, we are at the mercy of a battle between our base impulses for self-fulfillment and social and cultural mores which prohibit pure indulgence.

Competition (Encyclopedia of Business and Finance)
Competition is the battle between businesses to win consumer acceptance and loyalty. The free-enterprise system ensures that businesses make decisions about what to produce, how to produce it, and what price to charge for the product or service. Competition is a basic premise of the free-enterprise system because it is believed that having more than one business competing for the same consumers will cause the products and/or services to be provided at a better quality and a lower cost than if there were no competitors. In other words, competition should provide the consumers with the best value for their hard-earned dollar.
ASPECTS OF COMPETITION
To be successful in today's very competitive business world, it is important for businesses to be aware of what their competitors are doing and to find a way to compete by matching or improving on the competitors' product or service. For example, if Pepsi-Cola offers a new affeine-free soda, Coca-Cola may offer a new affeine-free soda with only one calorie. By offering an improvement on the competitor's product, Coca-Cola is trying to convince soft-drink consumers to buy the new coke product because it is an improvement on Pepsi's product.
While being aware of the competition and making a countermove is important, it is also very important to pay attention to changing consumer wants, needs, and values and to make the needed changes before the competition does. Doing research and development and being the first to provide a new product or service can give a company a competitive advantage in the marketplace. Once consumers purchase a product or service and are satisfied with it, they will typically purchase the same product again. Having a competitive advantage means that a company does something better than the competition. Having a competitive advantage might mean inventing a new product; providing the best quality, the lowest prices, or the best customer service; or having cutting-edge technology. To determine an area where a company might have a competitive advantage, a SWOT analysis is often done to identify the company's internal Strengths and Weaknesses and the external Opportunities and Threats. A SWOT analysis lets the company know in which area(s) it has a competitive advantage so it can concentrate on those areas in the production and marketing of its product(s) or service(s).
In addition to staying on top of changing consumer preferences, companies must constantly be looking for ways to cut costs and increase productivity. Companies must provide consumers with the best-quality product at the lowest cost while still making a profit if they are to be successful competitors in the long run. One way to remain competitive is through the use of technology. Technology can help speed up production processes through the use of robots or production lines, move information more accurately and more quickly through the use of computer systems, and assist in research and development proceedings.
Global competition has made gaining consumer acceptance an even tougher challenge for most businesses. Firms in other countries may be able to produce products and provide services at a lower cost than American businesses. In order to compete, American businesses must find other ways to win consumers. One way for businesses to accomplish this is through competitive differentiation. Competitive differentiation occurs when a firm somehow differentiates its product or service from that of competitors. Competitive differentiation may be an actual difference, such as a longer warranty or a lower price, but often the difference is only perceived. Difference in perception is usually accomplished through advertising, the purpose of which is to convince consumers that one company's product is different from another company's product. Common ways to differentiate a product or service include advertising a better-quality product, better service, better taste, or just a better image. Competitive differentiation is used extensively in the monopolistic form of competition, discussed below.
FORMS OF COMPETITION
Although each form has many aspects, not all of which can be considered here, competition can generally be classified into four main categories: perfect competition, monopolistic competition, oligopoly, and monopoly. (Table 1 summarizes the basic differences among these four types of competition.)
Perfect Competition Perfect competition (also known as pure competition) exists when a large number of sellers produce products or services that seem to be identical. These types of businesses are typically run on a small scale, and participants have no control over the selling price of their product because no one seller is large enough to dictate the price of the product. Instead, the price of the product is set by the market. There are many competitors in a perfect competition industry, and it is fairly easy to enter or leave the industry. While there are no ideal examples of perfect competition, agricultural products are considered to be the closest example in today's economy. The corn grown by one farmer is virtually identical to the corn grown by another farmer, and the current market controls the price the farmers receive for their crops. Perfect competition follows the law of supply and demand. If the price of a product is high, consumers will demand less of the product while the suppliers will want to supply more. If the price of a product is low, the consumers will demand more of the product, but the suppliers will be unwilling to sell much at such a low price. The equilibrium point is where the supply and the demand meet and determine the market price. For example, if the going market price for wheat is $5 a bushel and a farmer tries to sell wheat for $6 a bushel, no one will buy because they can get it for $5 a bushel from someone else. On the other hand, if a farmer offers to sell wheat for $4 a bushel, the crop will sell, but the farmer has lost money because the crop is worth $5 a bushel on the open market.
Monopolistic Competition Monopolistic competition exists when a large number of sellers produce a product or service that is perceived by consumers as being different from that of a competitor but is actually quite similar. This perception of difference is the result of product differentiation, which is the key to success in a monopolistic industry. Products can be differentiated based on price, quality, image, or some other feature, depending on the product. For example, there are many different brands of bath soap on the market today. Each brand of soap is similar because it is designed to get the user clean; however, each soap product tries to differentiate itself from the competition to attract consumers. One soap might claim that it leaves you with soft skin, while another soap might claim that it has a clean, fresh scent. Each participant in this market structure has some control over pricing, which means it can alter the selling price as long as consumers are still willing to buy its product at the new price. If one product costs twice as much as similar products on the market, chances are most consumers will avoid buying the more expensive product and buy the competitors' products instead. There can be few or many competitors (typically many) in a monopolistic industry, and it is somewhat difficult to enter or leave such an industry. Monopolistic products are typically found in retailing businesses. Some examples of monopolistic products and/or services are shampoo products, extermination services, oil changes, toothpaste, and fast-food restaurants.
Oligopoly An oligopoly (which is described more completely in another article) exists when there are few sellers in a certain industry. This occurs because a large investment is required to enter the industry, which makes it difficult to enter or leave. The businesses involved in an oligopoly type of industry are typically very large because they have the financial ability to make the needed investment. The type of products sold in an oligopoly can be similar or different, and each seller has some control over price. Examples of oligopolies include the automobile, airplane, and steel industries.
Monopoly A monopoly (which is described more completely in another article) exists when a single seller controls the supply of a good or service and prevents other businesses from entering the field. Being the only provider of a certain good or service gives the seller considerable control over price. Monopolies are prohibited by law in the United States; however, government-regulated
Types of Competition
|Characteristics||Perfect Competition||Monopolistic Competition||Oligopoly||Monopoly|
|Number of competitors||Many||Few to many||Very few||No direct competition|
|Ease of entry or exit from industry||Easy||Somewhat difficult||Difficult||Regulated by U.S. government|
|Similarity of goods/services offered by competing firms||Same||Seemingly different but may be quite similar||Similar or different||No directly competing products|
|Individual firm's control over price||None (set by the market)||Some||Some||Considerable (in true monopoly) Little (in regulated one)|

Competition (Encyclopedia of Science and Religion)
An important component of the neo-Darwinian theory of evolution, competition describes the theory that there is a struggle among organisms both of the same species (intraspecific) and between species (interspecific) for food, space, reproduction, and other requirements for existence. Through natural selection organisms develop adaptations to overcome or resist their own destruction in competition with the counter-adaptations developed by other organisms. These adaptations include physiological, chemical, and psychological traits. For example, organisms may evolve to become larger, more poisonous, or more aggressive. Such adaptations are not developed on the short timescale of individual lifetime but on the long evolutionary timescale of the species.

Competition (Encyclopedia of Business)
The notion of competition is very widely used in economics in general and in microeconomics in particular. Competition is also considered the basis for capitalist or free market economies. In standard usage of the term, competition may also imply certain virtues. Markets are the heart and soul of a capitalist economy, and varying degrees of competition lead to different market structures, with differing implications for the outcomes of the market place. This entry will discuss the following market structures that result from the successively declining degrees of competition in the market for a particular commodity. These elements are perfect competition, monopolistic competition, oligopoly, and monopoly. Based on the differing outcomes of different market structures, economists consider some market structures more desirable, from the point of view of the society, than others.
CHARACTERISTICS OF A MARKET STRUCTURE
Each of the above mentioned market structures describes a particular organization of a market in which certain key characteristics differ. The characteristics are: (a) number of firms in the market, (b) control over the price of the relevant product, (c) type of the product sold in the market, (d) barriers to new firms entering the market, and (e) existence of nonprice competition in the market. Each of these characteristics is briefly discussed below.
NUMBER OF FIRMS IN THE MARKET.
The number of firms in the market supplying the particular product under consideration forms an important basis for classifying market structures. The number of firms in an industry, according to economists, determines the extent of competition in the industry. Both in perfect competition and monopolistic competition, there are large numbers of firms or suppliers. Each of these firms supplies only a small portion of the total output for the industry. In oligopoly, there are only a few (presumably more than two) suppliers of the product. When there are only two sellers of the product, the market structure is often called duopoly. Monopoly is the extreme case where there is only one seller of the product in the market.
CONTROL OVER PRODUCT PRICE.
The extent to which an individual firm exercises control over the price of the product it sells is another important characteristic of a market structure. Under perfect competition, an individual firm has no control over the price of the product it sells. A firm under monopolistic competition or oligopoly has some control over the price of the product it sells. Finally, a monopoly firm is deemed to have considerable control over the price of its product.
TYPE OF THE PRODUCT SOLD IN THE MARKET.
The extent to which products of different firms in the industry can be differentiated is also a characteristic that is used in classifying market structures. Under perfect competition, all firms in the industry sell identical products. In other words, no firm can differentiate its product from those of other firms in the industry. There is some product differentiation under monopolistic competitionhe firms in the industry are assumed to produce somewhat different products. Under an oligopolistic market structure, firms may produce differentiated or identical products. Finally, in the case of a monopoly, product differentiation is not truly an issue, as there is only one firmhere are no other firms from whom it should differentiate its product.
BARRIERS TO NEW FIRMS ENTERING THE MARKET.
The difficulty or ease with which new firms can enter the market for a product is also a characteristic of market structures. New firms can enter market structures classified as perfect competition or monopolistic competition relatively easily. In these cases, barriers to entry are considered low, as only a small investment may be required to enter the market. In oligopoly, barriers to entry is considered very highuge amounts of investment, determined by the very nature of the product and the production process, are needed to enter these markets. Once again, monopoly constitutes the extreme case where the entry of new firms is blocked, usually by law. If for whatever reasons, new firms are allowed to enter a monopolistic market structure, it can no longer be termed a monopoly.
EXISTENCE OF NON-PRICE COMPETITION.
Market structures also differ to the extent that firms in industry compete with each other on the basis of non-price factors, such as, differences in product characteristics and advertising. There is no non-price competition under perfect competition. Firms under monopolistic competition make considerable use of instruments of non-price competition. Oligopolistic firms also make heavy use of non-price competition, Finally, while a monopolist also utilizes instruments of non-price competition, such as advertising, these are not designed to compete with other firms, as there are no other firms in the monopolist's industry.
We now turn to discussing each of the four market forms mentioned at the beginning, in light of the preceding characteristics used to classify market structures. The discussion that follows also provides additional details about the four market structures.
Perfect competition is an idealized version of market structure that provides a foundation for understanding how markets work in a capitalist economy. The other market structures can also be understood better when perfect competition is used as a standard of reference. Even so, perfect competition is not ordinarily well understood by the general public. For example, when business people speak of intense competition in the market for a product, they are, in all likelihood, referring to rival suppliers, about whom they have quite a bit of information. However, when economists refer to perfect competition, they are particularly referring to the impersonal nature of this market structure. The impersonality of the market organization is due to the existence of a large number of suppliers of the producthere are so many suppliers in the industry that no firm views another supplier as a competitor. Thus, the competition under perfect competition is impersonal.
To understand the nature of competition under the perfectly competitive market form, one should briefly examine the three conditions that are necessary before a market structure is considered "perfectly competitive." These are: homogeneity of the product sold in the industry, existence of many buyers and sellers, and perfect mobility of resources or factors of production. Homogeneity of product means that the product sold by any one seller in the market is identical to the product sold by any other supplier. The homogeneity of product has an important implication for the market: if products of different sellers are identical, buyers do not care who they buy from, so long as the price is also the same. While the first condition of a perfect market sounds extreme, it is, in fact, met in markets for many products. Wheat and corn are good examples. Wheat and corn produced by different farmers is essentially the same, and can thus be considered identical.
The second condition, existence of many buyers and sellers, again leads to an important outcome. When there is a large number of buyers or sellers, each individual buyer or seller is so small relative to the entire market that he or she does not have any power to influence the price of the product under consideration. As a result, whether a person is a buyer or a seller, he or she must accept the market price. All buyers and sellers in the market are effectively price takers, not price makers. The market as a whole establishes product prices, and individual buyers or sellers simply decide how much to buy or sell at the given market price. The third condition, perfect mobility of resources, requires that all factors of production (resources used in the production process) can be readily switched from one use to another. Furthermore, it is required that all buyers, sellers, and owners of resources have full knowledge of all relevant technological and economic data. The implication of the third condition is that resources move to the most profitable industry.
No industry in the world (now or in the past) satisfies all three conditions stipulated above fully. Thus, no industry in the world can be considered perfectly competitive in the strictest sense of the term. However, there are token examples of industries that come quite close to being a perfectly competitive market. Some markets for agricultural commodities, while not meeting all three conditions, come reasonably close to being characterized as perfectly competitive markets. The market for wheat, for example, can be considered a reasonable approximation. The wheat market is characterized by an almost homogenous product, and it has a large number of buyers and sellers. It thus satisfies the first two conditions fairly well. However, it is difficult to assert that resources employed in the wheat industry are perfectly mobile.
Despite the fact that no industry is truly perfectly competitive, it is still worthwhile to study perfect competition as a market structure. Conclusions derived from the study of the idealized version of perfect competition are often helpful in explaining behavior in the real world.
THE ECONOMICS OF PERFECT COMPETITION.
The study of the idealized version of perfect competition leads to some important conclusions regarding solutions to key economic problems, such as quantity of the relevant product produced, price charged, the mechanism of adjustment in the industry.
As mentioned earlier, under perfect competition, an individual supplier of the product has to take the market price as given. Given this price, the supplier determines how much to produce and sell. The quantity he or she decides to produce is the quantity that maximizes profit for the firm (more technically, where marginal cost of producing the product equals the market price of the product). The total production of all firms in the industry determines the market supply of the product under consideration. This market supply of the product, in conjunction with the total demand for the product by all consumers, determines the market price. Thus, while an individual buyer or seller is a price taker, the collective decisions affect the market price. Since the consumers of the product receive a price that is equal to the cost of production (on the margin), it is argued that consumers are treated fairly under perfect competition.
In addition, the total output produced under perfect competition is larger than, for example, under monopoly. To understand this, we should look at the mechanics of maximizing profit, the guiding force behind a supplier's output decision. In order to maximize profits, a supplier has to look at cost and revenue. Usually, it is assumed that a supplier's marginal cost (the cost of producing an additional unit of the product under consideration) rises ultimately. The producer then, in making the output decision, must compare the cost of producing an additional unit of the product with the revenue the sale of that additional unit (called the marginal revenue) brings to the firm. So long as the marginal revenue from the sale exceeds the marginal cost, there is a gain from producing that additional unithe unit adds more to revenue (proceeds) than to costs. The supplier will continue producing while the process is profitable (i.e., it increases profits or reduces loss). The firm will stop production where marginal revenue equals marginal costhis output level maximizes profits (or minimizes loss). In the case of a perfectly competitive firm, the market price for the product is also the marginal revenue. Since the firm is a price taker and supplies an insignificant portion of the total market supply of the product, it can sell as many units of the product as it desires at the going price. We will later show that this is not the case with a monopolist, for example. A monopolist stops production of the product before reaching the point where marginal cost of the product equals the market price of the product.
THE DESIRABILITY OF PERFECT COMPETITION.
Perfect competition is considered desirable for society for at least two reasons. First, the price charged to individuals equals the marginal cost of production to each firm. In other words, one can say sellers charge buyers a reasonable or fair price. Second, in general, output produced under a perfectly competitive market structure is larger than other market organizations. Thus, perfect competition becomes desirable also for the amount of the product supplied to consumers as a whole.
These are two reasons why a capitalist society adores the virtues of perfect competition. In fact, to maintain a reasonable amount of competition in a market is generally considered a goal of government regulatory policies. No single firm dominates the market under perfect competition; this parallels the status of an individual citizen in a democracy, a widely practiced form of government in capitalist countries.
As pointed out above, industries in the real world rarely satisfy the stringent conditions necessary to qualify as perfectly competitive market structures. The world in which we live is invariably characterized by competition of lesser degrees than stipulated by perfect competition. Many industries that we often deal with have market structures that are monopolistic competition or oligopoly. Apparel retail stores (with many stores and differentiated products) provide an example of monopolistic competition.
MAJOR CHARACTERISTICS OF MONOPOLISTIC COMPETITION.
As in the case of perfect competition, monopolistic competition is characterized by the existence of many sellers. Usually, if an industry has 50 or more firms (producing products that are close substitutes of each other), it is said to have a large number of firms. However, the number of firms must be large enough that each firm in the industry can expect its actions go unnoticed by rival firms.
Unlike perfect competition, the sellers under monopolistic competition differentiate competitive product. In other words, the products of these firms are not considered identical. It is, in fact, immaterial whether these products are actually different or simply perceived to be so. So long as consumers treat them as different products, they satisfy one of the characteristics of monopolistic competition. This product differentiation is considered a key attribute of monopolistic competition. In many U.S. markets, producers practice product differentiation by altering the physical composition, using special packaging, or simply claiming to have superior products based on brand images and/or advertising. Toothpastes and toilet papers are examples of differentiated products.
In addition to the existence of a large number of firms and product differentiation, relative ease of entry into the industry is considered another important requirement of a monopolistically competitive market organization. Also, there should be no collusion among firms in the industry, like price fixing or agreements regarding the market shares of individual companies. With the large number of firms that monopolistic competition requires, collusion is generally difficult, though not impossible.
The above mentioned characteristics of monopolistic competition basically yield a market form that is very competitive, but probably not to the extent of perfect competition.
THE ECONOMICS OF MONOPOLISTIC COMPETITION.
As in the case of perfect competition, a firm under monopolistic competition decides about the quantity of the product produced on the basis of the profit maximization principlet produces the quantity that maximizes the firm's profit. Also, conditions of profit maximization remain the samehe firm stops production where marginal revenue equals marginal cost of production. But unlike perfect competition, a firm under monopolistic competition has some control over the price it charges, as the firm differentiates its products from those of others. However, this price making power of a monopolistically competitive firm is rather small, since there are a large number of other firms in the industry with somewhat similar products. Remember that a perfectly competitive firm has no price making powerach firm is a price taker, as it produces a product identical to those produced by a large number of other firms in the industry.
An important consequence of the price making power of a monopolistically competitive firm is that when such a firm reduces price, it can attract customers buying other "brands" of the product. The opposite is also true when the firm increases the price it charges for its product. Because of this, price charged for a product is different from the marginal revenue for the product (marginal revenue refers to the increase in total revenue as a result of selling one more unit of the product under consideration). To understand this, consider, for example, that a firm reduces the price for its product. The firm must now sell all units at this lower price. Because the lower price applies to all units sold, not just the last or the marginal unit, price for the product is higher than the marginal revenue at each level of sale. It should be noted that as there are a large number of firms under monopolistic competition, individual firms in the industry are not appreciably affected by a particular firm's behavior.
As mentioned above, a monopolistically competitive firm stops production where marginal revenue equals marginal cost of productionhe output level that maximizes its profits (often called the equilibrium output for the firm).
THE DESIRABILITY OF MONOPOLISTIC COMPETITION.
Aforementioned profit maximizing behavior of a monopolistically competitive firm implies that now the price associated with the product (at the equilibrium or the profit maximizing output) is higher than marginal cost (which equals marginal revenue). Thus, the production under monopolistic competition does not take place to the point where price equals marginal cost of production. Remember that, with increased production, price charged (which is higher than marginal revenue at every level of output) is successively falling while the marginal cost of production is rising. Therefore, if a monopolistically competitive firm were to stop production where price is equal to marginal cost (a condition met under a perfectly competitive market structure), output produced would be greater than when it stops production where marginal revenue equals marginal cost (its profit maximizing output). The net result of the profit maximizing decisions of monopolistically competitive firms is that price charged under monopolistic competition is higher than under perfect competition. In addition, quantity of the commodity produced under monopolistic competition is simultaneously lower. Thus, both on the basis of price charged and output produced, monopolistic competition is less socially desirable than perfect competition.
Oligopoly is a fairly common market organization. In the United States, both the steel and auto industries (with three or so large firms) provide good examples of oligopolistic market structures.
MAJOR CHARACTERISTICS OF OLIGOPOLY.
An important characteristic of an oligopolistic market structure is the interdependence of firms in the industry. The interdependence, actual or perceived, arises from the small number of firms in the industry. However, unlike monopolistic competition, if an oligopolistic firm changes its price or output, it has perceptible effects on the sales and profits of its competitors in the industry. Thus, an oligopolist firm always considers the reactions of its rivals in formulating its pricing or output decisions.
There are huge, though not insurmountable, barriers to entering an oligopolistic market. These barriers can involve large financial requirements, availability of raw materials, access to the relevant technology, or simply patent rights of the firms currently in the industry. Several industries in the United States provide good examples of oligopolistic market structures with obvious barriers to entry. The U.S. auto industry provides an example of a market where financial barriers to entry exist. In order to efficiently operate an automobile plant, one needs upward of half a billion dollars of initial investment. The steel industry in the United States, on the other hand, provides an example of an oligopoly where barriers to entry have been created by the ownership of raw materials needed for producing the product. In this industry, a few huge firms own most of the available iron ore, a necessary raw material for steel production.
An oligopolistic industry is also typically characterized by economies of scale. Economies of scale in production imply that as the level of production rises the cost per unit of product falls for the use of any plant (generally, up to a point). Thus, economies of scale lead to an obvious advantage for a large producer. Once again, the automobile industry provides an example of a market structure where firms experience economies of scale. It should be noted that there may exist economies of scale in promotion just as there exist economies of scale in production. In the automobile industry, the promotion cost per unit of product falls as sales increase since promotion costs rise less than proportionately to sales.
ECONOMICS AND DESIRABILITY OF OLIGOPOLY.
There is no single theoretical framework that provides answers to output and pricing decisions under an oligopolistic market structure. Analyses exist only for special sets of circumstances. For example, if an oligopolistic firm cuts its price, it is met with price reductions by competing firms; however, if it raises the price of its product, rivals do not match the price increase. For this reason, prices may remain stable in an oligopolistic industry for a prolonged period of time.
It is hard to make concrete statements regarding price charged and quantity produced under oligopoly. However, from the point of view of the society, one can say that an oligopolistic market structure provides a fair degree of competition in the market place if the oligopolists in the market do not collude. Collusion occurs if firms in the industry agree to set price and/or quantity. In the United States, there are laws that make collusion illegal.
Monopoly can be considered the opposite of perfect competition. It is a market form in which there is only one seller. While at first glance a monopoly may appear to be a rare market structure, it is not so. Several industries in the United State have monopolies. Some utility companies provide examples of a monopolist.
CAUSES AND CHARACTERISTICS OF MONOPOLY.
There are many factors that give rise to a monopoly. For example, in the United States the inventor of an item has the exclusive right to produce that product for 17 years. Thus, a monopoly can exist in an industry because a patent was obtained for a product by its inventor. The United Shoe Machinery Company held such a monopoly in certain important shoe making equipment until 1954, when the monopoly was broken under the antitrust laws. A monopoly can also arise if a company owns the entire supply of a necessary material needed to produce a product. The Aluminum Company of America exercised such power until 1945, when its monopoly was also broken under provisions of the antitrust laws. A monopoly can be legally created by a government agency when it sells a market franchise a particular product or service. Often a monopoly so established is also regulated by the appropriate government agency. Provision of local telephone service in the United States provides an example of such a monopoly. Finally, a monopoly may arise due to declining cost of production for a particular product. In such a case the average cost of production falls and reaches a minimum at an output level that is sufficient to satisfy the entire market. In such an industry, rival firms will be eliminated until only the strongest firm (now the monopolist) is left in the market. This is often called a case of natural monopoly. A good example of a natural monopoly is the electricity industry. The electric power industry reaps benefits of economies of scale and yields decreasing average cost. A natural monopoly is usually regulated by the government.
THE ECONOMICS OF MONOPOLY.
Generally speaking, price and output decisions of a monopolist are similar to those of a monopolistically competitive firm, with the major distinction of a large number of firms under monopolistic competition and only one firm under monopoly. Thus, one may technically say that there is no competition under monopoly. This is not strictly true, as even a monopolist is threatened by indirect and potential competition. Like monopolistic competition, a monopolistic firm also maximizes its profits by producing up to the point where marginal revenue equals marginal cost. As the monopolist is a price maker and can increase the amount of sales by lowering the price, a monopolist does not lure consumers away from rivals, rather he or she induces them to buy more. Nevertheless, at any output level, the price charged by a monopolist is higher than the marginal revenue. As a result, a monopolist also does not produce to the point where price equals marginal cost (a condition met under a perfectly competitive market structure).
DESIRABILITY OF MONOPOLY.
An industry characterized by a monopolistic market structure produces less output and charges higher prices than under perfect competition (and presumably under monopolistic competition). Thus, on the basis of price charged and quantity produced, a monopoly is less desirable socially. However, a natural monopoly is generally considered desirable if the monopolist's price behavior can be regulated.
Industry in the real world is rarely characterized by perfect competition. In certain circumstances, society has to tolerate monopoly (say, the case of a natural monopoly or a monopoly due to patent rights). However, the idea of competition is very deeply ingrained in society. So long as there is a reasonable degree of competition (as in the case of monopolistic competition or oligopoly), society feels reasonably secure with respect to the working of its markets.
