Antitrust regulation is the law a government introduces to balance the share of economic power in business by ensuring healthy competition. Antitrust laws protect consumers from predatory business operations. In addition, they maintain fair competition in an economy.

Many countries have extensive laws to protect consumers and control how businesses operate. Some of the behaviors targeted by the antitrust laws include:

Mergers and Acquisitions. A merger is an action of two firms of approximately the same size coming together and operating as one business entity even though they are separately owned and run. On the other hand, an acquisition is where a firm takes over another firm and establishes itself as the new owner. In case an anticipated merger or acquisition will affect market competition negatively, the regulatory institution will prevent the merger or acquisition or provide other alternatives, such as selling a portion of the business to remedy the situation.

Price Collusion. Price collusion is a criminal offense where several companies conspire to keep the prices of certain goods high to make huge profits and hence reduce competition.

Price Discrimination. Price discrimination is a selling strategy where consumers are charged different prices for the same goods. The selling price, in this instance, is guided by what a seller thinks would be agreeable to their customer. Pure price discrimination occurs when a seller delivers products and services at the maximum price that the customer is willing to pay. Price discrimination jeopardizes fair competition.

Exclusive Dealings and Refusal to Deal. Exclusive dealings refer to cases where companies choose who to do business with and refuse to deal with other business entities. For instance, exclusive dealing may include the prevention of a supplier from selling to other buyers.

On the other hand, refusal to deal mainly occurs among monopolies who use their market dominance to choose their business partners.

Engaging in Predatory Pricing. Predatory pricing is a criminal offense of lowering prices of goods and services to lessen competition. Consequently, predatory pricing infringes the antitrust laws and breeds a monopoly market.

Anticompetitive Behavior by Dominant Companies in a Market. Some of the anti-competitive tricks dominant firms practice include abuse of dominance power. They do this by exclusively dealing with certain suppliers and retailers. For instance, Intel Corporation has been accused of abuse of its dominance by exclusively dealing with certain computer manufacturers and retailers.

In reaction to anti-competitive behaviors, the regulatory institutions may impose monetary sanctions. Alternatively, they may require the firms involved to change business, for example, adopt a change in marketing techniques. In a worst-case scenario, some countries, such as Germany and Denmark, may imprison an individual involved in a cartel.
