TheInfoList

A monopoly (from Greek el|μόνος|mónos|single, alone|label=none and el|πωλεῖν|pōleîn|to sell|label=none) exists when a specific person or enterprise is the only supplier of a particular commodity. This contrasts with a monopsony which relates to a single entity's control of a market to purchase a good or service, and with oligopoly and duopoly which consists of a few sellers dominating a market. Monopolies are thus characterized by a lack of economic competition to produce the good or service, a lack of viable substitute goods, and the possibility of a high monopoly price well above the seller's marginal cost that leads to a high monopoly profit. The verb ''monopolise'' or ''monopolize'' refers to the ''process'' by which a company gains the ability to raise prices or exclude competitors. In economics, a monopoly is a single seller. In law, a monopoly is a business entity that has significant market power, that is, the power to charge overly high prices, which is associated with a decrease in social surplus. Although monopolies may be big businesses, size is not a characteristic of a monopoly. A small business may still have the power to raise prices in a small industry (or market). A monopoly may also have monopsony control of a sector of a market. Likewise, a monopoly should be distinguished from a cartel (a form of oligopoly), in which several providers act together to coordinate services, prices or sale of goods. Monopolies, monopsonies and oligopolies are all situations in which one or a few entities have market power and therefore interact with their customers (monopoly or oligopoly), or suppliers (monopsony) in ways that distort the market. Monopolies can be established by a government, form naturally, or form by integration. In many jurisdictions, competition laws restrict monopolies due to government concerns over potential adverse effects. Holding a dominant position or a monopoly in a market is often not illegal in itself, however certain categories of behavior can be considered abusive and therefore incur legal sanctions when business is dominant. A government-granted monopoly or ''legal monopoly'', by contrast, is sanctioned by the state, often to provide an incentive to invest in a risky venture or enrich a domestic interest group. Patents, copyrights, and trademarks are sometimes used as examples of government-granted monopolies. The government may also reserve the venture for itself, thus forming a government monopoly, for example with a state-owned company. Monopolies may be naturally occurring due to limited competition because the industry is resource intensive and requires substantial costs to operate (e.g., certain railroad systems).

Market structures

In economics, the idea of monopolies is important in the study of management structures, which directly concerns normative aspects of economic competition, and provides the basis for topics such as industrial organization and economics of regulation. There are four basic types of market structures in traditional economic analysis: perfect competition, monopolistic competition, oligopoly and monopoly. A monopoly is a structure in which a single supplier produces and sells a given product or service. If there is a single seller in a certain market and there are no close substitutes for the product, then the market structure is that of a "pure monopoly". Sometimes, there are many sellers in an industry or there exist many close substitutes for the goods being produced, but nevertheless companies retain some market power. This is termed "monopolistic competition", whereas in an oligopoly, the companies interact strategically. In general, the main results from this theory compare the price-fixing methods across market structures, analyze the effect of a certain structure on welfare, and vary technological or demand assumptions in order to assess the consequences for an abstract model of society. Most economic textbooks follow the practice of carefully explaining the "perfect competition" model, mainly because this helps to understand departures from it (the so-called "imperfect competition" models). The boundaries of what constitutes a market and what does not are relevant distinctions to make in economic analysis. In a general equilibrium context, a good is a specific concept including geographical and time-related characteristics. Most studies of market structure relax a little their definition of a good, allowing for more flexibility in the identification of substitute goods.

Characteristics

A monopoly has these five characteristics: * ''Profit maximizer'': Maximizes profits. * ''Price maker'': Decides the price of the good or product to be sold, but does so by determining the quantity in order to demand the price desired by the firm. * ''High barriers to entry'': Other sellers are unable to enter the market of the monopoly. * ''Single seller'': In a monopoly, there is one seller of the good, who produces all the output. Therefore, the whole market is being served by a single company, and for practical purposes, the company is the same as the industry. * ''Price discrimination'': A monopolist can change the price or quantity of the product. They sell higher quantities at a lower price in a very elastic market, and sell lower quantities at a higher price in a less elastic market.

Sources of monopoly power

Monopolies derive their market power from barriers to entry – circumstances that prevent or greatly impede a potential competitor's ability to compete in a market. There are three major types of barriers to entry: economic, legal and deliberate. * ''Economic barriers'': Economic barriers include economies of scale, capital requirements, cost advantages and technological superiority. * ''Economies of scale'': Decreasing unit costs for larger volumes of production. Decreasing costs coupled with large initial costs, If for example the industry is large enough to support one company of minimum efficient scale then other companies entering the industry will operate at a size that is less than MES, and so cannot produce at an average cost that is competitive with the dominant company. And if the long-term average cost of the dominant company is constantly decreasing, then that company will continue to have the least cost method to provide a good or service. * ''Capital requirements'': Production processes that require large investments of capital, perhaps in the form of large research and development costs or substantial sunk costs, limit the number of companies in an industry: this is an example of economies of scale. * ''Technological superiority'': A monopoly may be better able to acquire, integrate and use the best possible technology in producing its goods while entrants either do not have the expertise or are unable to meet the large fixed costs (see above) needed for the most efficient technology. Thus one large company can often produce goods cheaper than several small companies. * ''No substitute goods'': A monopoly sells a good for which there is no close substitute. The absence of substitutes makes the demand for that good relatively inelastic, enabling monopolies to extract positive profits. * ''Control of natural resources'': A prime source of monopoly power is the control of resources (such as raw materials) that are critical to the production of a final good. * ''Network externalities'': The use of a product by a person can affect the value of that product to other people. This is the network effect. There is a direct relationship between the proportion of people using a product and the demand for that product. In other words, the more people who are using a product, the greater the probability that another individual will start to use the product. This reflects fads, fashion trends, social networks etc. It also can play a crucial role in the development or acquisition of market power. The most famous current example is the market dominance of the Microsoft office suite and operating system in personal computers. * ''Legal barriers'': Legal rights can provide opportunity to monopolise the market in a good. Intellectual property rights, including patents and copyrights, give a monopolist exclusive control of the production and selling of certain goods. Property rights may give a company exclusive control of the materials necessary to produce a good. * Advertising: Advertising is most important to sell the product because of the single user, they have to do it their own. * ''Manipulation'': A company wanting to monopolise a market may engage in various types of deliberate action to exclude competitors or eliminate competition. Such actions include collusion, lobbying governmental authorities, and force (see anti-competitive practices). In addition to barriers to entry and competition, barriers to exit may be a source of market power. Barriers to exit are market conditions that make it difficult or expensive for a company to end its involvement with a market. High liquidation costs are a primary barrier to exiting. Market exit and shutdown are sometimes separate events. The decision whether to shut down or operate is not affected by exit barriers. A company will shut down if price falls below minimum average variable costs.

Monopoly versus competitive markets

While monopoly and perfect competition mark the extremes of market structuresPng (1999), p. 268. there is some similarity. The cost functions are the same. Both monopolies and perfectly competitive (PC) companies minimize cost and maximize profit. The shutdown decisions are the same. Both are assumed to have perfectly competitive factors markets. There are distinctions, some of the most important distinctions are as follows: * ''Marginal revenue and price'': In a perfectly competitive market, price equals marginal cost. In a monopolistic market, however, price is set above marginal cost. * ''Product differentiation'': There is no product differentiation in a perfectly competitive market. Every product is perfectly homogeneous and a perfect substitute for any other. With a monopoly, there is great to absolute product differentiation in the sense that there is no available substitute for a monopolized good. The monopolist is the sole supplier of the good in question. A customer either buys from the monopolizing entity on its terms or does without. * ''Number of competitors'': PC markets are populated by an infinite number of buyers and sellers. A monopoly involves a single seller. * ''Barriers to entry'': Barriers to entry are factors and circumstances that prevent entry into market by would-be competitors and limit new companies from operating and expanding within the market. PC markets have free entry and exit. There are no barriers to entry, or exit competition. Monopolies have relatively high barriers to entry. The barriers must be strong enough to prevent or discourage any potential competitor from entering the market * ''Elasticity of demand'': The price elasticity of demand is the percentage change of demand caused by a one percent change of relative price. A successful monopoly would have a relatively inelastic demand curve. A low coefficient of elasticity is indicative of effective barriers to entry. A PC company has a perfectly elastic demand curve. The coefficient of elasticity for a perfectly competitive demand curve is infinite. * ''Excess profits'': Excess or positive profits are profit more than the normal expected return on investment. A PC company can make excess profits in the short term but excess profits attract competitors, which can enter the market freely and decrease prices, eventually reducing excess profits to zero. A monopoly can preserve excess profits because barriers to entry prevent competitors from entering the market. * ''Profit maximization'': A PC company maximizes profits by producing such that price equals marginal costs. A monopoly maximises profits by producing where marginal revenue equals marginal costs. The rules are not equivalent. The demand curve for a PC company is perfectly elastic – flat. The demand curve is identical to the average revenue curve and the price line. Since the average revenue curve is constant the marginal revenue curve is also constant and equals the demand curve, Average revenue is the same as price (AR = TR/Q = P x Q/Q = P). Thus the price line is also identical to the demand curve. In sum, D = AR = MR = P. * ''P-Max quantity, price and profit'': If a monopolist obtains control of a formerly perfectly competitive industry, the monopolist would increase prices, reduce production, and realise positive economic profits. * ''Supply curve'': in a perfectly competitive market there is a well defined supply function with a one-to-one relationship between price and quantity supplied. In a monopolistic market no such supply relationship exists. A monopolist cannot trace a short-term supply curve because for a given price there is not a unique quantity supplied. As Pindyck and Rubenfeld note, a change in demand "can lead to changes in prices with no change in output, changes in output with no change in price or both". Monopolies produce where marginal revenue equals marginal costs. For a specific demand curve the supply "curve" would be the price-quantity combination at the point where marginal revenue equals marginal cost. If the demand curve shifted the marginal revenue curve would shift as well and a new equilibrium and supply "point" would be established. The locus of these points would not be a supply curve in any conventional sense. The most significant distinction between a PC company and a monopoly is that the monopoly has a downward-sloping demand curve rather than the "perceived" perfectly elastic curve of the PC company. Practically all the variations mentioned above relate to this fact. If there is a downward-sloping demand curve then by necessity there is a distinct marginal revenue curve. The implications of this fact are best made manifest with a linear demand curve. Assume that the inverse demand curve is of the form x = a − by. Then the total revenue curve is TR = ay − by2 and the marginal revenue curve is thus MR = a − 2by. From this several things are evident. First, the marginal revenue curve has the same y intercept as the inverse demand curve. Second, the slope of the marginal revenue curve is twice that of the inverse demand curve. Third, the x intercept of the marginal revenue curve is half that of the inverse demand curve. What is not quite so evident is that the marginal revenue curve is below the inverse demand curve at all points. Since all companies maximise profits by equating MR and MC it must be the case that at the profit-maximizing quantity MR and MC are less than price, which further implies that a monopoly produces less quantity at a higher price than if the market were perfectly competitive. The fact that a monopoly has a downward-sloping demand curve means that the relationship between total revenue and output for a monopoly is much different than that of competitive companies.Frank (2009), p. 377. Total revenue equals price times quantity. A competitive company has a perfectly elastic demand curve meaning that total revenue is proportional to output. Thus the total revenue curve for a competitive company is a ray with a slope equal to the market price. A competitive company can sell all the output it desires at the market price. For a monopoly to increase sales it must reduce price. Thus the total revenue curve for a monopoly is a parabola that begins at the origin and reaches a maximum value then continuously decreases until total revenue is again zero. Total revenue has its maximum value when the slope of the total revenue function is zero. The slope of the total revenue function is marginal revenue. So the revenue maximizing quantity and price occur when MR = 0. For example, assume that the monopoly's demand function is P = 50 − 2Q. The total revenue function would be TR = 50Q − 2Q2 and marginal revenue would be 50 − 4Q. Setting marginal revenue equal to zero we have : $50-4Q=0$ : $-4Q=-50$ : $Q = 12.5$ So the revenue maximizing quantity for the monopoly is 12.5 units and the revenue maximizing price is 25. A company with a monopoly does not experience price pressure from competitors, although it may experience pricing pressure from potential competition. If a company increases prices too much, then others may enter the market if they are able to provide the same good, or a substitute, at a lesser price. The idea that monopolies in markets with easy entry need not be regulated against is known as the "revolution in monopoly theory". A monopolist can extract only one premium, and getting into complementary markets does not pay. That is, the total profits a monopolist could earn if it sought to leverage its monopoly in one market by monopolizing a complementary market are equal to the extra profits it could earn anyway by charging more for the monopoly product itself. However, the one monopoly profit theorem is not true if customers in the monopoly good are stranded or poorly informed, or if the tied good has high fixed costs. A pure monopoly has the same economic rationality of perfectly competitive companies, i.e. to optimise a profit function given some constraints. By the assumptions of increasing marginal costs, exogenous inputs' prices, and control concentrated on a single agent or entrepreneur, the optimal decision is to equate the marginal cost and marginal revenue of production. Nonetheless, a pure monopoly can – unlike a competitive company – alter the market price for its own convenience: a decrease of production results in a higher price. In the economics' jargon, it is said that pure monopolies have "a downward-sloping demand". An important consequence of such behaviour is that typically a monopoly selects a higher price and lesser quantity of output than a price-taking company; again, less is available at a higher price.

Inverse elasticity rule

A monopoly chooses that price that maximizes the difference between total revenue and total cost. The basic markup rule (as measured by the Lerner index) can be expressed as $\frac = \frac$, where $E_d$ is the price elasticity of demand the firm faces.Tirole, p. 66. The markup rules indicate that the ratio between profit margin and the price is inversely proportional to the price elasticity of demand. The implication of the rule is that the more elastic the demand for the product the less pricing power the monopoly has.

Market power

Market power is the ability to increase the product's price above marginal cost without losing all customers. Perfectly competitive (PC) companies have zero market power when it comes to setting prices. All companies of a PC market are price takers. The price is set by the interaction of demand and supply at the market or aggregate level. Individual companies simply take the price determined by the market and produce that quantity of output that maximizes the company's profits. If a PC company attempted to increase prices above the market level all its customers would abandon the company and purchase at the market price from other companies. A monopoly has considerable although not unlimited market power. A monopoly has the power to set prices or quantities although not both. A monopoly is a price maker. The monopoly is the market and prices are set by the monopolist based on their circumstances and not the interaction of demand and supply. The two primary factors determining monopoly market power are the company's demand curve and its cost structure. Market power is the ability to affect the terms and conditions of exchange so that the price of a product is set by a single company (price is not imposed by the market as in perfect competition). Although a monopoly's market power is great it is still limited by the demand side of the market. A monopoly has a negatively sloped demand curve, not a perfectly inelastic curve. Consequently, any price increase will result in the loss of some customers.

Price discrimination

Example

Assume that by a uniform pricing system the monopolist would sell five units at a price of $10 per unit. Assume that his marginal cost is$5 per unit. Total revenue would be $50, total costs would be$25 and profits would be $25. If the monopolist practiced price discrimination he would sell the first unit for$50 the second unit for $40 and so on. Total revenue would be$150, his total cost would be $25 and his profit would be$125.00.Lovell (2004), p. 266. Several things are worth noting. The monopolist acquires all the consumer surplus and eliminates practically all the deadweight loss because he is willing to sell to anyone who is willing to pay at least the marginal cost. Thus the price discrimination promotes efficiency. Secondly, by the pricing scheme price = average revenue and equals marginal revenue. That is the monopolist behaving like a perfectly competitive company.Frank (2008), p. 394. Thirdly, the discriminating monopolist produces a larger quantity than the monopolist operating by a uniform pricing scheme.Frank (2008), p. 266.

Classifying customers

Successful price discrimination requires that companies separate consumers according to their willingness to buy. Determining a customer's willingness to buy a good is difficult. Asking consumers directly is fruitless: consumers don't know, and to the extent they do they are reluctant to share that information with marketers. The two main methods for determining willingness to buy are observation of personal characteristics and consumer actions. As noted information about where a person lives (postal codes), how the person dresses, what kind of car he or she drives, occupation, and income and spending patterns can be helpful in classifying.

Monopoly and efficiency

According to the standard model, in which a monopolist sets a single price for all consumers, the monopolist will sell a lesser quantity of goods at a higher price than would companies by perfect competition. Because the monopolist ultimately forgoes transactions with consumers who value the product or service more than its price, monopoly pricing creates a deadweight loss referring to potential gains that went neither to the monopolist nor to consumers. Deadweight loss is the cost to society because the market isn't in equilibrium, it is inefficient. Given the presence of this deadweight loss, the combined surplus (or wealth) for the monopolist and consumers is necessarily less than the total surplus obtained by consumers by perfect competition. Where efficiency is defined by the total gains from trade, the monopoly setting is less efficient than perfect competition. It is often argued that monopolies tend to become less efficient and less innovative over time, becoming "complacent", because they do not have to be efficient or innovative to compete in the marketplace. Sometimes this very loss of psychological efficiency can increase a potential competitor's value enough to overcome market entry barriers, or provide incentive for research and investment into new alternatives. The theory of contestable markets argues that in some circumstances (private) monopolies are forced to behave ''as if'' there were competition because of the risk of losing their monopoly to new entrants. This is likely to happen when a market's barriers to entry are low. It might also be because of the availability in the longer term of substitutes in other markets. For example, a canal monopoly, while worth a great deal during the late 18th century United Kingdom, was worth much less during the late 19th century because of the introduction of railways as a substitute. Contrary to common misconception, monopolists do not try to sell items for the highest possible price, nor do they try to maximize profit per unit, but rather they try to maximize total profit.

Natural monopoly

A natural monopoly is an organization that experiences increasing returns to scale over the relevant range of output and relatively high fixed costs. A natural monopoly occurs where the average cost of production "declines throughout the relevant range of product demand". The relevant range of product demand is where the average cost curve is below the demand curve. When this situation occurs, it is always more efficient for one large company to supply the market than multiple smaller companies; in fact, absent government intervention in such markets, will naturally evolve into a monopoly. Often, a natural monopoly is the outcome of an initial rivalry between several competitors. An early market entrant that takes advantage of the cost structure and can expand rapidly can exclude smaller companies from entering and can drive or buy out other companies. A natural monopoly suffers from the same inefficiencies as any other monopoly. Left to its own devices, a profit-seeking natural monopoly will produce where marginal revenue equals marginal costs. Regulation of natural monopolies is problematic. Fragmenting such monopolies is by definition inefficient. The most frequently used methods dealing with natural monopolies are government regulations and public ownership. Government regulation generally consists of regulatory commissions charged with the principal duty of setting prices. To reduce prices and increase output, regulators often use average cost pricing. By average cost pricing, the price and quantity are determined by the intersection of the average cost curve and the demand curve.Samuelson and Marks (2003), p. 100. This pricing scheme eliminates any positive economic profits since price equals average cost. Average-cost pricing is not perfect. Regulators must estimate average costs. Companies have a reduced incentive to lower costs. Regulation of this type has not been limited to natural monopolies. Average-cost pricing does also have some disadvantages. By setting price equal to the intersection of the demand curve and the average total cost curve, the firm's output is allocatively inefficient as the price is less than the marginal cost (which is the output quantity for a perfectly competitive and allocatively efficient market). In 1848, J.S. Mill was the first individual to describe monopolies with the adjective "natural". He used it interchangeably with "practical". At the time, Mill gave the following examples of natural or practical monopolies: gas supply, water supply, roads, canals, and railways. In his ''Social Economics'', Friedrich von Wieser demonstrated his view of the postal service as a natural monopoly: "In the face of uchsingle-unit administration, the principle of competition becomes utterly abortive. The parallel network of another postal organization, beside the one already functioning, would be economically absurd; enormous amounts of money for plant and management would have to be expended for no purpose whatever."

Government-granted monopoly

A government-granted monopoly (also called a "''de jure'' monopoly") is a form of ''coercive monopoly'', in which a government grants exclusive privilege to a private individual or company to be the sole provider of a commodity. Monopoly may be granted explicitly, as when potential competitors are excluded from the market by a specific law, or implicitly, such as when the requirements of an administrative regulation can only be fulfilled by a single market player, or through some other legal or procedural mechanism, such as patents, trademarks, and copyright.

Monopolist shutdown rule

A monopolist should shut down when price is less than average variable cost for every output level – in other words where the demand curve is entirely below the average variable cost curve. Under these circumstances at the profit maximum level of output (MR = MC) average revenue would be less than average variable costs and the monopolists would be better off shutting down in the short term.

Breaking up monopolies

In an unregulated market, monopolies can potentially be ended by new competition, breakaway businesses, or consumers seeking alternatives. In a regulated market, a government will often either regulate the monopoly, convert it into a publicly owned monopoly environment, or forcibly fragment it (see Antitrust law and trust busting). Public utilities, often being naturally efficient with only one operator and therefore less susceptible to efficient breakup, are often strongly regulated or publicly owned. American Telephone & Telegraph (AT&T) and Standard Oil are often cited as examples of the breakup of a private monopoly by government. The Bell System, later AT&T, was protected from competition first by the Kingsbury Commitment, and later by a series of agreements between AT&T and the Federal Government. In 1984, decades after having been granted monopoly power by force of law, AT&T was broken up into various components, MCI, Sprint, who were able to compete effectively in the long-distance phone market. These breakups are due to the presence of deadweight loss and inefficiency in a monopolistic market, causing the Government to intervene on behalf of consumers and society in order to incite competition. While the sentiment among regulators and judges has generally recommended that breakups are not as remedies for antitrust enforcement, recent scholarship has found that this hostility to breakups by administrators is largely unwarranted. In fact, some scholars have argued breakups, even if incorrectly targeted, could arguably still encourage collaboration, innovation, and efficiency.

Law

The law regulating dominance in the European Union is governed by Article 102 of the ''Treaty on the Functioning of the European Union'' which aims at enhancing the consumer's welfare and also the efficiency of allocation of resources by protecting competition on the downstream market. The existence of a very high market share does not always mean consumers are paying excessive prices since the threat of new entrants to the market can restrain a high-market-share company's price increases. Competition law does not make merely having a monopoly illegal, but rather abusing the power a monopoly may confer, for instance through exclusionary practices (i.e. pricing high just because it is the only one around.) It may also be noted that it is illegal to try to obtain a monopoly, by practices of buying out the competition, or equal practices. If one occurs naturally, such as a competitor going out of business, or lack of competition, it is not illegal until such time as the monopoly holder abuses the power.

Establishing dominance

First it is necessary to determine whether a company is dominant, or whether it behaves "to an appreciable extent independently of its competitors, customers and ultimately of its consumer". Establishing dominance is a two-stage test. The first thing to consider is market definition which is one of the crucial factors of the test. It includes relevant product market and relevant geographic market.

Relevant product market

As the definition of the market is of a matter of interchangeability, if the goods or services are regarded as interchangeable then they are within the same product market. For example, in the case of ''United Brands v Commission'', it was argued in this case that bananas and other fresh fruit were in the same product market and later on dominance was found because the special features of the banana made it could only be interchangeable with other fresh fruits in a limited extent and other and is only exposed to their competition in a way that is hardly perceptible. The demand substitutability of the goods and services will help in defining the product market and it can be access by the ‘hypothetical monopolist’ test or the ‘SSNIP’ test .

Relevant geographic market

It is necessary to define it because some goods can only be supplied within a narrow area due to technical, practical or legal reasons and this may help to indicate which undertakings impose a competitive constraint on the other undertakings in question. Since some goods are too expensive to transport where it might not be economic to sell them to distant markets in relation to their value, therefore the cost of transporting is a crucial factor here. Other factors might be legal controls which restricts an undertaking in a Member States from exporting goods or services to another. Market definition may be difficult to measure but is important because if it is defined too broadly, the undertaking may be more likely to be found dominant and if it is defined too narrowly, the less likely that it will be found dominant.

Market shares

As with collusive conduct, market shares are determined with reference to the particular market in which the company and product in question is sold. It does not in itself determine whether an undertaking is dominant but work as an indicator of the states of the existing competition within the market. The Herfindahl-Hirschman Index (HHI) is sometimes used to assess how competitive an industry is. It sums up the squares of the individual market shares of all of the competitors within the market. The lower the total, the less concentrated the market and the higher the total, the more concentrated the market.Whish R and others, ''Competition Law'' (8th Edition, OUP 2015) In the US, the merger guidelines state that a post-merger HHI below 1000 is viewed as not concentrated while HHIs above that will provoke further review. By European Union law, very large market shares raise a presumption that a company is dominant, which may be rebuttable. A market share of 100% may be very rare but it is still possible to be found and in fact it has been identified in some cases, for instance the ''AAMS v Commission'' case. Undertakings possessing market share that is lower than 100% but over 90% had also been found dominant, for example, Microsoft v Commission case. In the AKZO v Commission case, the undertaking is presumed to be dominant if it has a market share of 50%. There are also findings of dominance that are below a market share of 50%, for instance, United Brands v Commission, it only possessed a market share of 40% to 45% and still to be found dominant with other factors. The lowest yet market share of a company considered "dominant" in the EU was 39.7%.If a company has a dominant position, then there is a special responsibility not to allow its conduct to impair competition on the common market however these will all falls away if it is not dominant. When considering whether an undertaking is dominant, it involves a combination of factors. Each of them cannot be taken separately as if they are, they will not be as determinative as they are when they are combined together.Guidance on Article 102 Enforcement Priorities 009/ref> Also, in cases where an undertaking has previously been found dominant, it is still necessary to redefine the market and make a whole new analysis of the conditions of competition based on the available evidence at the appropriate time.

Other related factors

According to the Guidance, there are three more issues that must be examined. They are actual competitors that relates to the market position of the dominant undertaking and its competitors, potential competitors that concerns the expansion and entry and lastly the countervailing buyer power. * Actual Competitors Market share may be a valuable source of information regarding the market structure and the market position when it comes to accessing it. The dynamics of the market and the extent to which the goods and services differentiated are relevant in this area. * Potential Competitors It concerns with the competition that would come from other undertakings which are not yet operating in the market but will enter it in the future. So, market shares may not be useful in accessing the competitive pressure that is exerted on an undertaking in this area. The potential entry by new firms and expansions by an undertaking must be taken into account, therefore the barriers to entry and barriers to expansion is an important factor here. * Countervailing buyer power Competitive constraints may not always come from actual or potential competitors. Sometimes, it may also come from powerful customers who have sufficient bargaining strength which come from its size or its commercial significance for a dominant firm.

Types of abuses

There are three main types of abuses which are exploitative abuse, exclusionary abuse and single market abuse. * Exploitative abuse It arises when a monopolist has such significant market power that it can restrict its output while increasing the price above the competitive level without losing customers. This type is less concerned by the Commission than other types. * Exclusionary abuse This is most concerned about by the Commissions because it is capable of causing long- term consumer damage and is more likely to prevent the development of competition. An example of it is exclusive dealing agreements. * Single market abuse It arises when a dominant undertaking carrying out excess pricing which would not only have an exploitative effect but also prevent parallel imports and limits intra- brand competition.

Examples of abuses

* Limiting supply * Predatory pricing or undercutting * Price discrimination * Refusal to deal and exclusive dealing * Tying (commerce) and product bundling Despite wide agreement that the above constitute abusive practices, there is some debate about whether there needs to be a causal connection between the dominant position of a company and its actual abusive conduct. Furthermore, there has been some consideration of what happens when a company merely attempts to abuse its dominant position. To provide a more specific example, economic and philosophical scholar Adam Smith cites that trade to the East India Company has, for the most part, been subjected to an exclusive company such as that of the English or Dutch. Monopolies such as these are generally established against the nation in which they arose out of. The profound economist goes on to state how there are two types of monopolies. The first type of monopoly is one which tends to always attract to the particular trade where the monopoly was conceived, a greater proportion of the stock of the society than what would go to that trade originally. The second type of monopoly tends to occasionally attract stock towards the particular trade where it was conceived, and sometimes repel it from that trade depending on varying circumstances. Rich countries tended to repel while poorer countries were attracted to this. For example, The Dutch company would dispose of any excess goods not taken to the market in order to preserve their monopoly while the English sold more goods for better prices. Both of these tendencies were extremely destructive as can be seen in Adam Smith's writings.

Historical monopolies

Origin

The term "monopoly" first appears in Aristotle's ''Politics''. Aristotle describes Thales of Miletus's cornering of the market in olive presses as a monopoly (''μονοπώλιον''). Another early reference to the concept of “monopoly” in a commercial sense appears in tractate Demai of the Mishna (2nd century C.E.), regarding the purchasing of agricultural goods from a dealer who has a monopoly on the produce (chapter 5; 4). The meaning and understanding of the English word 'monopoly' has changed over the years.

Monopolies of resources

Salt

Vending of common salt (sodium chloride) was historically a natural monopoly. Until recently, a combination of strong sunshine and low humidity or an extension of peat marshes was necessary for producing salt from the sea, the most plentiful source. Changing sea levels periodically caused salt "famines" and communities were forced to depend upon those who controlled the scarce inland mines and salt springs, which were often in hostile areas (e.g. the Sahara desert) requiring well-organised security for transport, storage, and distribution. The Salt Commission was a legal monopoly in China. Formed in 758, the Commission controlled salt production and sales in order to raise tax revenue for the Tang Dynasty. The "Gabelle" was a notoriously high tax levied upon salt in the Kingdom of France. The much-hated levy had a role in the beginning of the French Revolution, when strict legal controls specified who was allowed to sell and distribute salt. First instituted in 1286, the Gabelle was not permanently abolished until 1945.

Coal

Robin Gollan argues in ''The Coalminers of New South Wales'' that anti-competitive practices developed in the coal industry of Australia's Newcastle as a result of the business cycle. The monopoly was generated by formal meetings of the local management of coal companies agreeing to fix a minimum price for sale at dock. This collusion was known as "The Vend". The Vend ended and was reformed repeatedly during the late 19th century, ending by recession in the business cycle. "The Vend" was able to maintain its monopoly due to trade union assistance, and material advantages (primarily coal geography). During the early 20th century, as a result of comparable monopolistic practices in the Australian coastal shipping business, the Vend developed as an informal and illegal collusion between the steamship owners and the coal industry, eventually resulting in the High Court case Adelaide Steamship Co. Ltd v. R. & AG.

Petroleum

Standard Oil was an American oil producing, transporting, refining, and marketing company. Established in 1870, it became the largest oil refiner in the world. John D. Rockefeller was a founder, chairman and major shareholder. The company was an innovator in the development of the business trust. The Standard Oil trust streamlined production and logistics, lowered costs, and undercut competitors. "Trust-busting" critics accused Standard Oil of using aggressive pricing to destroy competitors and form a monopoly that threatened consumers. Its controversial history as one of the world's first and largest multinational corporations ended in 1911, when the United States Supreme Court ruled that Standard was an illegal monopoly. The Standard Oil trust was dissolved into 33 smaller companies; two of its surviving "child" companies are ExxonMobil and the Chevron Corporation.

Steel

U.S. Steel has been accused of being a monopoly. J. P. Morgan and Elbert H. Gary founded U.S. Steel in 1901 by combining Andrew Carnegie's Carnegie Steel Company with Gary's Federal Steel Company and William Henry "Judge" Moore's National Steel Company. At one time, U.S. Steel was the largest steel producer and largest corporation in the world. In its first full year of operation, U.S. Steel made 67 percent of all the steel produced in the United States. However, U.S. Steel's share of the expanding market slipped to 50 percent by 1911, and antitrust prosecution that year failed.

Diamonds

De Beers settled charges of price fixing in the diamond trade in the 2000s. De Beers is well known for its monopoloid practices throughout the 20th century, whereby it used its dominant position to manipulate the international diamond market. The company used several methods to exercise this control over the market. Firstly, it convinced independent producers to join its single channel monopoly, it flooded the market with diamonds similar to those of producers who refused to join the cartel, and lastly, it purchased and stockpiled diamonds produced by other manufacturers in order to control prices through limiting supply. In 2000, the De Beers business model changed due to factors such as the decision by producers in Russia, Canada and Australia to distribute diamonds outside the De Beers channel, as well as rising awareness of blood diamonds that forced De Beers to "avoid the risk of bad publicity" by limiting sales to its own mined products. De Beers' market share by value fell from as high as 90% in the 1980s to less than 40% in 2012, having resulted in a more fragmented diamond market with more transparency and greater liquidity. In November 2011 the Oppenheimer family announced its intention to sell the entirety of its 40% stake in De Beers to Anglo American plc thereby increasing Anglo American's ownership of the company to 85%.0The transaction was worth £3.2 billion ($5.1 billion) in cash and ended the Oppenheimer dynasty's 80-year ownership of De Beers. Utilities A public utility (or simply "utility") is an organization or company that maintains the infrastructure for a public service or provides a set of services for public consumption. Common examples of utilities are electricity, natural gas, water, sewage, cable television, and telephone. In the United States, public utilities are often natural monopolies because the infrastructure required to produce and deliver a product such as electricity or water is very expensive to build and maintain. Western Union was criticized as a "price gouging" monopoly in the late 19th century. American Telephone & Telegraph was a telecommunications giant. AT&T was broken up in 1984. In the case of Telecom New Zealand, local loop unbundling was enforced by central government. Telkom is a semi-privatised, part state-owned South African telecommunications company. Deutsche Telekom is a former state monopoly, still partially state owned. Deutsche Telekom currently monopolizes high-speed VDSL broadband network.Kevin J. O'Brien IHT.com Regulators in Europe fight for independence, ''International Herald Tribune'', November 9, 2008, Accessed November 14, 2008. The Long Island Power Authority (LIPA) provided electric service to over 1.1 million customers in Nassau and Suffolk counties of New York, and the Rockaway Peninsula in Queens. The Comcast Corporation is the largest mass media and communications company in the world by revenue.IfM – Comcast/NBCUniversal, LLC Mediadb.eu (2013-11-15). Retrieved on 2013-12-09. It is the largest cable company and home Internet service provider in the United States, and the nation's third largest home telephone service provider. Comcast has a monopoly in Boston, Philadelphia, and many other small towns across the US. Transportation The United Aircraft and Transport Corporation was an aircraft manufacturer holding company that was forced to divest itself of airlines in 1934. Iarnród Éireann, the Irish Railway authority, is a current monopoly as Ireland does not have the size for more companies. The Long Island Rail Road (LIRR) was founded in 1834, and since the mid-1800s has provided train service between Long Island and New York City. In the 1870s, LIRR became the sole railroad in that area through a series of acquisitions and consolidations. In 2013, the LIRR's commuter rail system is the busiest commuter railroad in North America, serving nearly 335,000 passengers daily. Foreign trade Dutch East India Company was created as a legal trading monopoly in 1602. The ''Vereenigde Oost-Indische Compagnie'' enjoyed huge profits from its spice monopoly through most of the 17th century. The British East India Company was created as a legal trading monopoly in 1600. The East India Company was formed for pursuing trade with the East Indies but ended up trading mainly with the Indian subcontinent, North-West Frontier Province, and Balochistan. The Company traded in basic commodities, which included cotton, silk, indigo dye, salt, saltpetre, tea and opium. Professional sports Major League Baseball survived U.S. antitrust litigation in 1922, though its special status is still in dispute as of 2009. The National Football League survived antitrust lawsuit in the 1960s but was convicted of being an illegal monopoly in the 1980s. Other examples of monopolies * Microsoft has been the defendant in multiple antitrust suits on strategy ''embrace, extend and extinguish''. They settled antitrust litigation in the U.S. in 2001. In 2004 Microsoft was fined 493 million euros by the European Commission which was upheld for the most part by the Court of First Instance of the European Communities in 2007. The fine was US$1.35 billion in 2008 for noncompliance with the 2004 rule. * Monsanto has been sued by competitors for antitrust and monopolistic practices. They have between 70% and 100% of the commercial GMO seed market in a small number of crops. * AAFES has a monopoly on retail sales at overseas U.S. military installations. * The State retail alcohol monopolies of Norway (Vinmonopolet), Sweden (Systembolaget), Finland (Alko), Iceland (Vínbúð), Ontario (LCBO), Quebéc (SAQ), British Columbia (Liquor Distribution Branch), among others. * The Walt Disney Company is one of the largest mass media and entertainment conglomerates in the world, and has acquired huge amounts of assets, companies and corporations - both national and international. The 2019 purchase of the majority of 20th Century Fox's assets sparked controversy.

Countering monopolies

According to professor Milton Friedman, laws against monopolies cause more harm than good, but unnecessary monopolies should be countered by removing tariffs and other regulation that upholds monopolies. However, professor Steve H. Hanke believes that although private monopolies are more efficient than public ones, often by a factor of two, sometimes private natural monopolies, such as local water distribution, should be regulated (not prohibited) by, e.g., price auctions. Thomas DiLorenzo asserts, however, that during the early days of utility companies where there was little regulation, there were no natural monopolies and there was competition. Only when companies realized that they could gain power through government did monopolies begin to form. Baten, Bianchi and Moser find historical evidence that monopolies which are protected by patent laws may have adverse effects on the creation of innovation in an economy. They argue that under certain circumstances, compulsory licensing – which allows governments to license patents without the consent of patent-owners – may be effective in promoting invention by increasing the threat of competition in fields with low pre-existing levels of competition.
