Because the the absence of competition, monopolies tend to earn far-ranging economic profits. These earnings should attract vigorous competition as defined in Perfect Competition, and yet, because of one details characteristic the monopoly, they carry out not. Barriers come entry room the legal, technological, or market forces that discourage or stop potential rivals from entering a market. Barriers to entry can variety from the simple and conveniently surmountable, such together the cost of renting retail space, come the very restrictive. Because that example, there are a finite variety of radio frequencies accessible for broadcasting. Once the rights to every one of them have been purchased, no new competitors can get in the market.

You are watching: Patents and copyrights were established by the government to reduce oligopoly and monopoly power.

In some cases, obstacles to entrance may lead to monopoly. In various other cases, they might limit competition come a couple of firms. Barriers may block entry even if the for sure or firms at this time in the sector are earning profits. Thus, in markets with far-ranging barriers come entry, that is not true that abnormally high profits will attract new firms, and that this entry of new firms will eventually reason the price to decrease so that enduring firms earn only a common level of profit in the lengthy run.

There space two types of monopoly, based upon the types of obstacles to entry they exploit. One is natural monopoly, whereby the barriers to entry room something other than legitimate prohibition. The other is legal monopoly, where laws prohibit (or severely limit) competition.

Natural Monopoly

Economies that scale can combine with the size of the market to limit competition. (This design template was presented in Cost and Industry Structure). Number 1 gift a long-run average price curve because that the plane manufacturing industry. The shows economic situations of range up to an output of 8,000 planes every year and a price that P0, then continuous returns to range from 8,000 to 20,000 planes every year, and also diseconomies of scale at a quantity of production better than 20,000 planes every year.

Now consider the market demand curve in the diagram, i m sorry intersects the long-run average cost (LRAC) curve at an output level that 6,000 planes every year and also at a price P1, which is higher than P0. In this situation, the market has room for just one producer. If a 2nd firm make the efforts to enter the market at a smaller sized size, speak by producing a quantity of 4,000 planes, climate its average expenses will be higher than the existing firm, and it will certainly be unable to compete. If the second firm do the efforts to enter the market at a larger size, like 8,000 planes per year, then it could produce in ~ a lower average cost—but it might not market all 8,000 planes the it produced because of insufficient need in the market.

Figure 1. economic situations of Scale and also Natural Monopoly. In this market, the demand curve intersects the long-run average price (LRAC) curve in ~ its downward-sloping part. A natural monopoly occurs as soon as the quantity demanded is less than the minimum amount it takes come be in ~ the bottom the the long-run average price curve.

This situation, when economic situations of range are big relative come the amount demanded in the market, is called a organic monopoly. Herbal monopolies regularly arise in markets where the marginal expense of adding secondary customer is really low, as soon as the fixed prices of the all at once system space in place. As soon as the key water pipes space laid through a neighborhood, the marginal price of providing water company to another home is fairly low. Once electrical power lines are mounted through a neighborhood, the marginal cost of providing extr electrical organization to one more home is really low. It would certainly be costly and also duplicative because that a 2nd water agency to enter the market and also invest in a whole 2nd set of main water pipes, or for a second electricity agency to go into the market and invest in a whole new set of electrical wires. These markets offer an example where, since of economies of scale, one producer deserve to serve the entire market an ext efficiently 보다 a variety of smaller producers that would must make duplicate physical resources investments.

A natural monopoly can likewise arise in smaller sized local industries for assets that are an overwhelming to transport. Because that example, cement manufacturing exhibits economies of scale, and also the amount of cement inquiry in a local area might not it is in much bigger than what a solitary plant deserve to produce. Moreover, the costs of carrying cement end land space high, and also so a cement plant in one area without accessibility to water transportation might be a herbal monopoly.

Control of a physical Resource

Another kind of natural monopoly occurs once a firm has regulate of a scarce physics resource. In the U.S. Economy, one historical instance of this pattern occurred when ALCOA—the Aluminum agency of America—controlled most of the supply of bauxite, a key mineral offered in making aluminum. Ago in the 1930s, when ALCOA controlled most that the bauxite, various other firms were simply unable to produce enough aluminum to compete.

As an additional example, the bulk of global diamond manufacturing is regulated by DeBeers, a multi-national agency that has actually mining and production operations in south Africa, Botswana, Namibia, and also Canada. It likewise has exploration tasks on four continents, if directing a worldwide distribution network the rough cut diamonds. Despite in current years they have actually experienced growing competition, their impact on the unstable diamond industry is quiet considerable.

Legal Monopoly

For part products, the government erects obstacles to entry by prohibiting or limiting competition. Under U.S. Law, no organization however the U.S. Postal company is legally enabled to provide first-class mail. Numerous states or cities have actually laws or regulations that enable households a choice of only one electrical company, one water company, and one company to choose up the garbage. Most legal monopolies are taken into consideration utilities—products crucial for everyday life—that room socially advantageous to have. Together a consequence, the government permits producers to come to be regulated monopolies, to insure that an ideal amount of these commodities is listed to consumers. Additionally, legal monopolies are regularly subject to economies of scale, so it provides sense to permit only one provider.

Promoting Innovation

A trademark is an identifying symbol or name for a specific good, choose Chiquita bananas, Chevrolet cars, or the Nike “swoosh” that appears on shoes and athletic gear. Around 1.9 million trademarks room registered v the U.S. Government. A firm can renew a trademark over and over again, as lengthy as it continues to be in energetic use.

Government limitations on competition provided to be even more common in the joined States. For many of the twenty century, only one call company—AT&T—was legally permitted to administer local and also long distance service. Indigenous the 1930s to the 1970s, one collection of federal regulations restricted which destinations airlines could pick to paris to and also what fares they can charge; another collection of regulations limited the interest prices that banks could salary to depositors; yet one more specified what trucking firms might charge customers.

What commodities are taken into consideration utilities depends, in part, top top the easily accessible technology. Fifty years ago, local and also long distance telephone company was noted over wires. It did no make lot sense to have actually multiple companies building multiple solution of wiring across towns and across the country. AT&T shed its syndicate on lengthy distance business when the an innovation for giving phone service adjusted from wires come microwave and satellite transmission, so that multiple firms might use the very same transmission mechanism. The very same thing occurred to local service, particularly in current years, with the development in cellular phone systems.

The combination of renovations in manufacturing technologies and a general sense that the sectors could provide services adequately led to a wave of deregulation, starting in the so late 1970s and also continuing right into the 1990s. This wave removed or diminished government restrictions on the that company that could enter, the prices that could be charged, and the amounts that might be created in countless industries, consisting of telecommunications, airlines, trucking, banking, and electricity.

Around the world, indigenous Europe to Latin America come Africa and also Asia, many governments continue to control and also limit compete in what those governments perceive come be vital industries, consisting of airlines, banks, steel companies, oil companies, and also telephone companies.
