In microeconomics, management, and international political economy, vertical integration is an arrangement in which the supply chain of a company is integrated and owned by that company. Usually each member of the supply chain produces a different product or (market-specific) service, and the products combine to satisfy a common need. It is contrasted with horizontal integration, wherein a company produces several items that are related to one another. Vertical integration has also described management styles that bring large portions of the supply chain not only under a common ownership but also into one corporation (as in the 1920s when the Ford River Rouge Complex began making much of its own steel rather than buying it from suppliers).
Vertical integration and expansion is desired because it secures supplies needed by the firm to produce its product and the market needed to sell the product. Vertical integration and expansion can become undesirable when its actions become anti-competitive and impede free competition in an open marketplace. Vertical integration is one method of avoiding the hold-up problem. A monopoly produced through vertical integration is called a vertical monopoly.
Vertical integration is often closely associated with vertical expansion which, in economics, is the growth of a business enterprise through the acquisition of companies that produce the intermediate goods needed by the business or help market and distribute its product. Such expansion is desired because it secures the supplies needed by the firm to produce its product and the market needed to sell the product. Such expansion can become undesirable when its actions become anti-competitive and impede free competition in an open marketplace.
The result is a more efficient business with lower costs and more profits. On the undesirable side, when vertical expansion leads toward monopolistic control of a product or service then regulative action may be required to rectify anti-competitive behavior. Related to vertical expansion is lateral expansion, which is the growth of a business enterprise through the acquisition of similar firms, in the hope of achieving economies of scale.
Vertical expansion is also known as a vertical acquisition. Vertical expansion or acquisitions can also be used to increase sales and to gain market power. The acquisition of DirecTV by News Corporation is an example of forwarding vertical expansion or acquisition. DirecTV is a satellite TV company through which News Corporation can distribute more of its media content: news, movies, and television shows. The acquisition of NBC by Comcast is an example of backward vertical integration. For example, in the United States, protecting the public from communications monopolies that can be built in this way is one of the missions of the Federal Communications Commission.
Scholar's findings suggest that a reduction in inefficiencies caused by the market vertical value chains including downstream prices, double mark-up can be negated with vertical integration. Application in more complex environments can help firms overcome market failures. (markets with high transaction costs or assets specificities) Scholars also identified potential risks and boundaries which may occur under vertical integration. This includes the potential competitor, the enhancements to horizontal collusion, development of barriers to entry. However, it is still debated over if vertical integration expected efficiencies can lead to competitive harm to the market. Some conclude that in many cases that the efficiencies outweigh the potential risks.
Contrary to horizontal integration, which is a consolidation of many firms that handle the same part of the production process, vertical integration is typified by one firm engaged in different parts of production (e.g., growing raw materials, manufacturing, transporting, marketing, and/or retailing). Vertical integration is the degree to which a firm owns its upstream suppliers and its downstream buyers. The differences depend on where the firm is placed in the order of the supply chain.
There are three varieties of vertical integration: backward (upstream) vertical integration, forward (downstream) vertical integration, and balanced (both upstream and downstream) vertical integration.
Disintermediation is a form of vertical integration when purchasing departments take over the former role of wholesalers to source products.
Problems that can stem from vertical integration can include large capital investments needed to set up and buy factories and maintain efficient profits. Rapid technology development can increase integration difficulties and further increase costs. The requirement of different business skills venturing into new portions of the supply chain can be challenging for the firm. Implementation of vertical integration can yield increased profit margins or eliminate the leverage that other firms or buyers may have over the firm.
There are internal and external society-wide gains and losses stemming from vertical integration, which vary according to the state of technology in the industries involved, roughly corresponding to the stages of the industry lifecycle.[clarification needed] Static technology represents the simplest case, where the gains and losses have been studied extensively. A vertically integrated company usually fails when transactions within the market are too risky or the contracts to support these risks are too costly to administer, such as frequent transactions and a small number of buyers and sellers.
During a hunting trip American explorer and scientist Clarence Birdseye discovered the beneficial effects of "quick-freezing". For example, fish caught a few days previously that were kept in ice remained in perfect condition.
In 1924, Clarence Birdseye patented the "Birdseye Plate Froster" and established the General Seafood Corporation. In 1929, Birdseye's company and the patent were bought by Postum Cereals and Goldman Sachs Trading Corporation. It was later known as General Foods. They kept the Birdseye name, which was split into two words (Birds eye) for use as a trademark. Birdseye was paid $20 million for the patents and $2 million for the assets.
Birds Eye was one of the pioneers in the frozen food industry. During these times, there was not a well-developed infrastructure to produce and sell frozen foods. Hence Birds Eye developed its own system by using vertical integration. Members of the supply chain, such as farmers and small food retailers, couldn't afford the high cost of equipment, so Birdseye provided it to them.
Until now, Birds Eye has faded slowly because they have fixed costs associated with vertical integration, such as property, plants, and equipment that cannot be reduced significantly when production needs decrease. The Birds Eye company used vertical integration to create a larger organization structure with more levels of command. This produced a slower information processing rate, with the side effect of making the company so slow that it couldn't react quickly. Birds Eye didn't take advantage of the growth of supermarkets until ten years after the competition did. The already-developed infrastructure did not allow Birdseye to quickly react to market changes.
In order to increase profits and gain more market share, Alibaba, a China-based company, has implemented vertical integration deepening its company holdings to more than the e-commerce platform. Alibaba has built its leadership in the market by gradually acquiring complementary companies in a variety of industries including delivery and payments.
One of the earliest, largest and most famous examples of vertical integration was the Carnegie Steel company. The company controlled not only the mills where the steel was made, but also the mines where the iron ore was extracted, the coal mines that supplied the coal, the ships that transported the iron ore and the railroads that transported the coal to the factory, the coke ovens where the coal was coked, etc. The company focused heavily on developing talent internally from the bottom up, rather than importing it from other companies.[full citation needed] Later, Carnegie established an institute of higher learning to teach the steel processes to the next generation.
Oil companies, both multinational (such as ExxonMobil, Royal Dutch Shell, ConocoPhillips or BP) and national (e.g., Petronas) often adopt a vertically integrated structure, meaning that they are active along the entire supply chain from locating deposits, drilling and extracting crude oil, transporting it around the world, refining it into petroleum products such as petrol/gasoline, to distributing the fuel to company-owned retail stations, for sale to consumers. Standard Oil is a famous example of both horizontal and vertical integration, combining extraction, transport, refinement, wholesale distribution, and retail sales at company-owned gas stations.
Telephone companies in most of the 20th century, especially the largest (the Bell System) were integrated, making their own telephones, telephone cables, telephone exchange equipment and other supplies.
Apple Inc. is one the key figure in a successful vertically integrated business model. Apple Inc. centered its business strategy on its own development of integrated hardware and software. Present-day Apple Inc. produces and designs most of the products in-house and does not allow its own hardware and operating system to be licensed out. This strategic decision has allowed Apple Inc. to apply its company vision to its products. This differentiates itself from other companies by becoming a company focused on quality products. They have further pursued vertical integration through its product distribution by placing its stores in major cities. 
From the early 1920s through the early 1950s, the American motion picture had evolved into an industry controlled by a few companies, a condition known as a "mature oligopoly", as it was led by eight major film studios, the most powerful of which were the "Big Five" studios: MGM, Warner Brothers, 20th Century Fox, Paramount Pictures, and RKO. These studios were fully integrated, not only producing and distributing films, but also operating their own movie theaters; the "Little Three", Universal Studios, Columbia Pictures, and United Artists, produced and distributed feature films but did not own theaters.
The issue of vertical integration (also known as common ownership) has been the main focus of policy makers because of the possibility of anti-competitive behaviors affiliated with market influence. For example, in United States v. Paramount Pictures, Inc., the Supreme Court ordered the five vertically integrated studios to sell off their theater chains and all trade practices were prohibited (United States v. Paramount Pictures, Inc., 1948). The prevalence of vertical integration wholly predetermined the relationships between both studios and networks[clarification needed] and modified criteria in financing. Networks began arranging content initiated by commonly owned studios and stipulated a portion of the syndication revenues in order for a show to gain a spot on the schedule if it was produced by a studio without common ownership. In response, the studios fundamentally changed the way they made movies and did business. Lacking the financial resources and contract talent they once controlled, the studios now relied on independent producers supplying some portion of the budget in exchange for distribution rights.
Certain media conglomerates may, in a similar manner, own television broadcasters (either over-the-air or on cable), production companies that produce content for their networks, and also own the services that distribute their content to viewers (such as television and internet service providers). AT&T, Bell Canada, Comcast, Sky plc, and Rogers Communications are vertically integrated in such a manner—operating media subsidiaries (such as WarnerMedia, Bell Media, NBCUniversal, and Rogers Media), and provide "triple play" services of television, internet, and phone service in some markets (such as Bell Satellite TV/Bell Internet, Rogers Cable, Xfinity, and Sky's satellite TV and internet services). Additionally, Bell and Rogers own wireless providers, Bell Mobility and Rogers Wireless, while Comcast is partnered with Verizon Wireless for an Xfinity-branded MVNO. Similarly, Sony has media holdings through its Sony Pictures division, including film and television content, as well as television channels, but is also a manufacturer of consumer electronics that can be used to play content from itself and others, including televisions, phones, and PlayStation video game consoles. AT&T is the first ever vertical integration where a mobile phone company and a film studio company are under same umbrella.

Vertical integration through production and marketing contracts have also become the dominant model for livestock production. Currently, 90% of poultry, 69% of hogs, and 29% of cattle are contractually produced through vertical integration. The USDA supports vertical integration because it has increased food productivity. However, "... contractors receive a large share of farm receipts, formerly assumed to go to the operator's family".
Under production contracts, growers raise animals owned by integrators. Farm contracts contain detailed conditions for growers, who are paid based on how efficiently they use feed, provided by the integrator, to raise the animals. The contract dictates how to construct the facilities, how to feed, house, and medicate the animals, and how to handle manure and dispose of carcasses. Generally, the contract also shields the integrator from liability. Jim Hightower, in his book, Eat Your Heart Out, discusses this liability role enacted by large food companies. He finds that in many cases of agricultural vertical integration, the integrator (food company) denies the farmer the right of entrepreneurship. This means that the farmer can only sell under and to the integrator. These restrictions on specified growth, Hightower argues, strips the selling and producing power of the farmer. The producer is ultimately limited by the established standards of the integrator. Yet, at the same time, the integrator still keeps the responsibility connected to the farmer. Hightower sees this as ownership without reliability.
Under marketing contracts, growers agree in advance to sell their animals to integrators under an agreed price system. Generally, these contracts shield the integrator from liability for the grower's actions and the only negotiable item is a price.
In the United States new automobiles can not be sold at dealerships owned by the same company that produced them but are protected by state franchise laws.
EssilorLuxottica, the company that merged with Essilor and Luxottica, occupies up to 30% of the global market share as well as representing billions of pairs of lenses and frames sold annually. Before the merger, Luxottica also owned 80% of the market share of companies that produce corrective and protective eyewear as well as owning many retailers, optical departments at Target and Sears, and key eye insurance groups, such as EyeMed, many of which are already part of the now merged company.
In the United States, major vertical mergers have included CVS Health's purchase of Aetna, and Cigna's purchase of Express Scripts.
Amazon.com has been criticized for being anti-competitive as both an owner and participant of its dominant online marketplace. In office products, Sycamore Partners owns both Staples, Inc., a major retailer, and Essendant, a dominant wholesaler.
Before a wave of deregulation at the end of 20th century, most electric utilities were vertically integrated and provided electric generation, transmission, distribution, and sales. These were not just conglomerates with a common accounting department: there was just one profit center in sales, and costs of transmission and distribution were not separated. Partial deregulation in the US in 1978 (PURPA) forced the utilities to buy electricity outside if the rates were competitive; this gave rise to independent power producers. The other deviation from the vertical integration model were local distribution companies in some towns and regions. In the US 250 vertically integrated companies provided 85% of electrical generation.
In economic theory, vertical integration has been studied in the literature on incomplete contracts that was developed by Oliver Hart and his coauthors. Consider a seller of an intermediate product that is used by a buyer to produce a final product. The intermediate product can only be produced with the help of specific physical assets (e.g., machines, buildings). Should the buyer own the assets (vertical integration) or should the seller own the assets (non-integration)? Suppose that today the parties have to make relationship-specific investments. Since today complete contracts cannot be written, the two parties will negotiate tomorrow about how to divide the returns of the investments. Since the owner is in a better bargaining position, he will have stronger incentives to invest. Hence, whether vertical integration is desirable or not depends on whose investments are more important. Hart's theory has been extended by several authors. For instance, DeMeza and Lockwood (1998) have studied different bargaining games, while Schmitz (2006) has introduced asymmetric information into the incomplete contracting setup. In these extended models, vertical integration can sometimes be optimal even if only the seller has to make an investment decision.
