A cartel is a group of independent market participants who collude with each other in order to improve their profits and dominate the market. Cartels are usually associations in the same sphere of business, and thus an alliance of rivals. Most jurisdictions consider it anti-competitive behavior and have outlawed such practices. Cartel behavior includes price fixing, bid rigging, and reductions in output. The doctrine in economics that analyzes cartels is cartel theory. Cartels are distinguished from other forms of collusion or anti-competitive organization such as corporate mergers. Etymology The word cartel comes from the Italian word cartello, which means a "leaf of paper" or "placard", and is itself derived from the Latin charta meaning "card". The Italian word became cartel in Middle French, which was borrowed into English. In English, the word was originally used for a written agreement between warring nations to regulate the treatment and exchange of prisoners from the 1690s onward. From 1899 onwards, the usage of the word became generalized as to mean any intergovernmental agreement between rival nations. The use of the English word cartel to describe an economic group rather than international agreements was derived much later in the 1800s from the German Kartell, which also has its origins in the French cartel. It was first used between German railway companies in 1846 to describe tariff- and technical standardization efforts. The first time the word was referred to describe a kind of restriction of competition was by the Austro-Hungarian political scientist Lorenz von Stein, who wrote on tariff cartels: History Cartels have existed since ancient times. Guilds in the European Middle Ages, associations of craftsmen or merchants of the same trade, have been regarded as cartel-like. Tightly organized sales cartels existed in the mining industry of the late Middle Ages, like the 1301 salt syndicate in France and Naples, or the Alaun cartel of 1470 between the Papal State and Naples. Both unions had common sales organizations for overall production called the Societas Communis Vendicionis ('Common Sales Society'). Laissez-faire (liberal) economic conditions dominated Europe and North America in the 18th and 19th centuries. Around 1870, cartels first appeared in industries formerly under free-market conditions. Although cartels existed in all economically developed countries, the core area of cartel activities was in central Europe. The German Empire and Austria-Hungary were nicknamed the "lands of the cartels". Cartels were also widespread in the United States during the
