A cartel is a group of formally independent producers whose goal it is to fix prices, to limit supply and to limit competition. Cartels are prohibited by antitrust laws in most countries; however, they continue to exist nationally and internationally, formally and informally. Note that a single entity that holds a monopoly by this definition cannot be a cartel, though it may be guilty of abusing said monopoly in other ways. As such, it is inaccurate to describe (for example) Microsoft or AT&T as cartels. Cartels usually occur in oligopolies, where there are a small number of sellers.
Price fixing is often practiced internationally. When the agreement to control price is sanctioned by a multilateral treaty or protected by national sovereignty, no antitrust actions may be initiated. Examples of such price fixing include oil whose price is partly controlled by the supply by OPEC countries. Also international airline tickets have prices fixed by agreement with the IATA, a practice for which there is a specific exception in antitrust law.
International price fixing by private entities can be prosecuted under the antitrust laws of more than 100 countries. Examples of prosecuted international cartels are lysine, citric acid, graphite electrodes, and bulk vitamins.
OPEC: As its name suggests, OPEC is organised by sovereign states. It cannot be held to antitrust enforcement in other jurisdictions by virtue of the doctrine of state immunity under public international law. However, members of the group do frequently break rank to increase production quotas.
Many trade organizations, especially in industries dominated by only a few major companies, have been accused of being fronts for cartels:
Some, usually critics of labor unions, claim exactly the same applies to trade unions, which allegedly act like cartels (being a group of producers) with similar benefits and drawbacks.
An example of a new international cartel is the one created by the members of the Asian Racing Federation and documented in the Good Neighbour Policy signed on September 1, 2003.
