Anti-competitive practices

Anti-competitive practices are business or government practices that prevent or reduce competition in a market. Antitrust laws ensure businesses do not engage in competitive practices that harm other, usually smaller, businesses or consumers. These laws are formed to promote healthy competition within a free market by limiting the abuse of monopoly power. Competition allows companies to compete in order for products and services to improve; promote innovation; and provide more choices for consumers. In order to obtain greater profits, some large enterprises take advantage of market power to hinder survival of new entrants. Anti-competitive behavior can undermine the efficiency and fairness of the market, leaving consumers with little choice to obtain a reasonable quality of service.

Anti-competitive behavior refers to actions taken by a business or organization to limit, restrict or eliminate competition in a market, usually in order to gain an unfair advantage or dominate the market. These practices are often considered illegal or unethical and can harm consumers, other businesses and the broader economy. Anti-competitive behavior is used by business and governments to lessen competition within the markets so that monopolies and dominant firms can generate supernormal profit margins and deter competitors from the market. Therefore, it is heavily regulated and punishable by law in cases where it substantially affects the market.

Anti-competitive practices are commonly only deemed illegal when the practice results in a substantial dampening in competition, hence why for a firm to be punished for any form of anti-competitive behavior they generally need to be a monopoly or a dominant firm in a duopoly or oligopoly who has significant influence over the market.

Anti-competitive behavior can be grouped into two classifications. Horizontal restraints regard anti-competitive behavior that involves competitors at the same level of the supply chain. These practices include mergers, cartels, collusions, price-fixing, price discrimination and predatory pricing. On the other hand, the second category is vertical restraint which implements restraints against competitors due to anti-competitive practice between firms at different levels of the supply chain e.g. supplier-distributor relationships. These practices include exclusive dealing, refusal to deal/sell, resale price maintenance and more.

Horizontal integration can result in economies of scale, economies of density and be anti-competitive. When two companies with similar products or product characteristics merge horizontally, there is less competition. Horizontal mergers can also easily lead to a monopoly, reducing consumers' choices and indirectly harming consumers' interests.

Vertical integration can result in economies of scope and reduce the hold-up problem and be anti-competitive. In absence of perfect competition Chicago school of economics argues vertical integration may be pro-competitive by reducing double marginalization.

Unfair competition includes a number of areas of law involving acts by one competitor or group of competitors which harm another in the field, and which may give rise to criminal offenses and civil causes of action. The most common actions falling under the banner of unfair competition include:
