Economists describe the Sicilian Mafia as a business that sells protection and trust
Members of the Sicilian Mafia never called it the Mafia. Insiders used Cosa Nostra, our thing, and the popular label probably spread after an 1863 Palermo stage hit. The sociologist Diego Gambetta later argued it works like a cartel of private protection firms, thriving wherever the state fails to enforce contracts.
The organisation grew up in mid-nineteenth-century Sicily as a way of controlling land and farming, then spread into politics, construction and finance by the mid-twentieth century, and later into drug trafficking and money laundering. Its basic unit is the family, or cosca, which claims a town, village or city district as its turf. Members style themselves men of honour. Emigration carried the model abroad, most notably to the United States, where the American Mafia took shape.
The word itself is slippery. In nineteenth-century Sicilian, mafiusu suggested swagger and boldness in a man, while the feminine form meant an attractive woman; some have proposed Arabic roots dating from the island's time as an emirate. A popular play about a Palermo prison gang, staged in 1863, featured a boss, an initiation and a code of silence without ever using the word, and a police prefect's report put mafia on paper in 1865. Joseph Valachi told a US Senate panel in 1963 that American members spoke of cosa nostra; in 1984 Tommaso Buscetta told the magistrate Giovanni Falcone that Sicilians used the same term.
Scholars long disagreed about whether it was an organisation at all. Leopoldo Franchetti called it an industry of violence in 1876. The ethnographer Giuseppe Pitrè and the sicilianismo movement treated it as an attitude of fierce self-worth rather than a structure, and field researchers such as Henner Hess and Anton Blok largely followed that line into the early 1980s. Falcone's investigations and Pino Arlacchi's 1983 study of mafia enterprise showed structured, business-minded groups.
Gambetta's 1993 analysis explains the demand. Where people distrust one another and courts are slow, mafiosi act as guarantors of deals, especially between criminals who cannot turn to the law. Yet protected clients gain an incentive to cheat the unprotected, so overall distrust rises and transaction costs climb. Gambetta's remedies were economic: move drugs and cigarettes out of the black market, open up public contracting and make votes harder to buy. It is also distinct from Calabria's 'Ndrangheta and the Camorra of Campania.
