Definitions

Various conflicting definitions of "barrier to entry" have been put forth since the 1950s. This has caused there to be no clear consensus on which definition should be used. McAfee, Mialon, and Williams list seven common definitions in economic literature in chronological order including: In 1956, Joe S. Bain used the definition "an advantage of established sellers in an industry over potential entrant sellers, which is reflected in the extent to which established sellers can persistently raise their prices above competitive levels without attracting new firms to enter the industry." McAfee et al. criticized this as being tautological by putting the "consequences of the definition into the definition itself." In 1968,
George Stigler George Joseph Stigler (; January 17, 1911 – December 1, 1991) was an American economist. He was the 1982 laureate in Nobel Memorial Prize in Economic Sciences and is considered a key leader of the Chicago school of economics. Early life and ...
defined an entry barrier as "A cost of producing that must be borne by a firm which seeks to enter an industry but is not borne by firms already in the industry." McAfee et al. criticized the phrase "is not borne" as being confusing and incomplete by implying that only current costs need be considered. In 1979, Franklin M. Fisher gave the definition "anything that prevents entry when entry is socially beneficial." McAfee et al. criticized this along the same lines as Bain's definition. In 1994, Dennis Carlton and Jeffrey Perloff gave the definition, "anything that prevents an entrepreneur from instantaneously creating a new firm in a market." Carlton and Perloff then dismiss their own definition as impractical and instead use their own definition of a "long-term barrier to entry" which is defined very closely to the definition in the introduction. A primary barrier to entry is a cost that constitutes an economic barrier to entry on its own. An ancillary barrier to entry is a cost that does not constitute a barrier to entry by itself, but reinforces other barriers to entry if they are present. An antitrust barrier to entry is "a cost that delays entry and thereby reduces social welfare relative to immediate but equally costly entry". This contrasts with the concept of ''economic barrier to entry'' defined above, as it can delay entry into a market but does not result in any cost-advantage to incumbents in the market. All economic barriers to entry are antitrust barriers to entry, but the converse is not true.

in 2008 showed stated new entrants to an industry have the desire to gain market share, and often substantial resources. The seriousness of the threat of entry depends on the barriers present and on the reaction from existing competitors. The following shows the 6 main sources of barriers to entry: * Economies of scale * Product differentiation * Capital requirements * Cost disadvantages independent of size * Access to distribution channels * Government policy Furthermore, a potential new market entrants expectations about the reaction of the existing competitors within the industry will also be a contributing factor on their decision to enter the market. The company will likely have second thoughts if incumbents have previously lashed out at new entrants or if: * Incumbents possess substantial resources to fight back, such as excess cash and unused borrowing power. * Incumbents seem likely to cut prices because of a desire to keep market shares or because of industry wide excess capacity. * Industry growth is slow, affecting its ability to absorb the new arrival, likely causing the financial performance of all parties to decline.

s can make it difficult for other manufacturers to enter an industry. This is a particular problem if, prior to entry, the other firms in the market use intensive distribution strategies in order to restrict the access of potential entrants to distributors. In response, if access to existing distribution channels is too difficult, new entrants may create their own. For example, new low-cost airlines often encourage passengers to book online instead of through travel agents. *

s may represent a kind of entry barrier for a particular product or service if the market is dominated by one or a few well-known names. Incumbent firms may have an exclusive right to use the brand name, making it expensive or impossible for new entrants to license rights to names. *Capital requirements - Many industries require the investment of large financial resources to start a new business, which deters new entrants. For example, new airlines require millions of dollars for purchasing planes, staff training etc. In addition, new entrants often experience serious difficulties in raising funds for unrecoverable expenses, such as advertising and R&D. In the pharmaceutical industry, for instance, companies may invest heavily in research in order to develop Covid vaccines, then end up with disappointing results and lose all of their investment. * Restrictive practices – Established policies may protect existing players and restrict entry. For instance, air transport agreements may make it difficult for new airlines to obtain

Indeed, switching costs are often intentionally made high in order to discourage customers from changing suppliers and adopting the technological innovations provided by others. *

Contentious examples

The following examples are sometimes cited as barriers to entry, but don't fit all the commonly cited definitions of a barrier to entry. Many of these fit the definition of antitrust barriers to entry or ancillary economic barriers to entry. *
Economies of scale In microeconomics, economies of scale are the cost advantages that enterprises obtain due to their scale of operation, and are typically measured by the amount of output produced per unit of time. A decrease in cost per unit of output enables ...
– Cost advantages raise the stakes in a market, which can deter and delay entrants into the market. Bulk buying offers buyers larger negotiating power to get the lowest price and they take advantage on that. This makes scale economies an antitrust barrier to entry, but they can also be ancillary. The per-unit cost will be lower in scale economies due to the spread of fixed costs to larger volumes, technology efficiencies and better supplier terms, therefore new entrants join the industry either on a large scale or at a cost disadvantage. Cost advantages can sometimes be quickly reversed by advances in technology. For example, the development of

/Demand-side benefits of scale – When a good or service has a value that increases on average for every additional customer, this exerts a similar antitrust and ancillary barrier to that of economies of scale. Customers are more willing to buy crucial products from larger companies than newcomers. It increases the difficulty of entering the industry or reduces the initial profit margins for new entrants. * Government regulations – Government regulations are rules having the force of law, prescribed by a superior or competent authority, relating to the actions of those under the authority's control. Licences, for example, may be required when entering a specific field, particularly in industries that are heavily protected by the government. As a result, the field is dominated by government-owned firms (e.g energy), or existing players are protected in the market (e.g Taxi service or TV). The regulations themselves may set the barriers for not letting others to enter a market, or requirements for licenses and permits may raise the level of investment required, creating an antitrust barrier to entry. However, sometimes government regulations may make entry easier, such as AIR-21 which requires airports to make facilities available to access by all carriers. *

The Market Power Theory of Advertising
'' Economics Glossary – Terms Beginning with M. Accessed June 19, 2008.
Here, established firms' use of advertising creates a consumer perceived difference in its brand from other brands to a degree that consumers see its brand as a slightly different product. Since the brand is seen as a slightly different product, products from existing or potential competitors cannot be perfectly substituted in place of the established firm's brand. This makes it hard for new competitors to gain consumer acceptance. It reflected by brand promoting and the increase of customer loyalties. * Capital –

s, which can increase the strength of barriers to entry. Sunk costs may also lead to monopoly profits, improper resource allocation and low efficiency. For capital-intensive industries, entrants will also need much more financial capital. * Uncertainty – When a market actor has various options with overlapping possible profits, choosing any one of them has an opportunity cost. This cost might be reduced by waiting until conditions are clearer, which can result in an ancillary antitrust barrier. * Incumbency advantages independent of scale – Incumbents often have advantages over newcomers, including proprietary technology, know-how, favorable access to raw materials, favorable geographic locations, established brand reputation and learning curve cost advantages.

, require a large upfront investment in technology which will deter potential entrants. The existing firms in the market may also use efficient investments in research and development to increase technological economies of scale, and boost industry development, which work against entrants who lack the funding and resources to enter the market. However, critics also point out that entry barriers can reduce the efficiency of R&D because firms have no incentive to efficiently invest in innovation. * Customer loyalty – Large incumbent firms may have existing customers loyal to established products. As a result, the presence of established strong brands within a market can be a barrier to entry. * Control of

can hinder entrants, who may be unable to set their prices as low as incumbents. As a result, industries with high barriers to entry often contain a monopoly or oligopoly with dominant power in terms of price. This dominance allows them to charge a higher price or, if other firms join the market, to use their market power and cash flow to lower prices, beating out the new competition. * Technology and technological change - Technological change, often seen in high technology sectors, can have a tremendous impact on economies of scale. * Market concentration - Market concentration, though it usually has only a minor effect, can still work against new entrants. * Seller concentration - Seller concentration can have a major effect on new entrants, making it difficult for them to enter the market, contributing further to seller concentration. * Divisionalization - Typically in highly profitable oligopolistic industries, it is cheaper for an incumbent to establish a new department than it would be for new entrants. * Selling expenses - A change in demand function may be endogenous to market entry due to sales efforts. * Incumbent's expected reaction to market entry - If incumbent firms expect new entrants to represent a threat, and are capable of preventing market entry, they may take action to prevent new entrants from competing. * Possession of strategic raw materials - An ability to access strategic raw materials provides advantages for the accessing companies, such as an absolute cost advantage.

Market structure

A structural barrier to entry is a cost incurred by new entrants to a market that is caused by inherent industry conditions, such as upfront capital investment, economies of scale and network effects. For example, the cost to develop a factory and obtain the initial capital required for manufacturing can be seen as a structural barrier to entry. A strategic barrier to entry is a cost incurred by new entrants that is artificially created or enhanced by existing firms. This could take the form of exclusive contracts, whether supply or demand-side, or through price manipulation in non-competitive markets. A market with

can allow for medium barriers to entry. Because the enterprises can earn their short-term revenue through innovation and marketing new products to push the price higher than average costs and marginal costs, barriers to entry can be made higher. However, due to the low cost of the information in monopolistic competition, the barrier of entry is lower than in oligopolies or monopolies as new entrants come. An
