Business and economic competition in most countries is often limited or restricted. Competition often is subject to legal restrictions. For example, competition may be legally prohibited, as in the cases of a government monopoly or of a government-granted monopoly. Governments may institute tariffs, subsidies or other protectionist measures in order to prevent or reduce competition. Depending on the respective economic policy, pure competition is to a greater or lesser extent regulated by competition policy and competition law. Another component of these activities is the discovery process, with instances of higher government regulations typically leading to less competitive businesses being launched.
