Toughness is a dichotomous variable driving the protection market toward monopoly

Evidence

But violence is not employed for enforcement purposes alone; competition among guarantors is perhaps the most common reason for its use. Protectors compete in terms of toughness: he who fights hardest not only eliminates his vanquished competitors but also advertises himself to customers as a reliably tough character. Several accounts in the literature describe how honor—better defined as the reputation for supplying credible protection—among mafiosi is a variable attribute which has nothing to do with birth (see Hess 1973; Arlacchi 1983). By winning violent contests, a mafioso increases his honor at the expense of potential or established competitors in what amounts to a zero-sum game (see Bonanno 1983: 127). Most accounts of intermafioso conflict depict its descriptive and phenomenological peculiarities but stop short of explaining exactly why it happens. In fact, the characteristics of the commodity mafiosi sell mean that whenever competition emerges, violence must follow almost automatically. If one of the structural features of protection is the ruthlessness of the supplier, then the logic of the commodity itself invites comparisons in terms of ruthlessness. The mafioso who hits hardest will be perceived as the most reliable protector. Toughness is a quality lacking in subtlety, for one either has it or does not. There is no coming in second best, only winning or losing. While the quality of most commodities is distributed over a continuous scale with products at every level, the ability to resort successfully to violence functions as a dichotomous variable: that is, within any given context one and only one supplier has what it takes, and if buyers cannot count on his services, they can never feel safe. Thus we see an additional reason why the protection market is monopolistic. — Diego Gambetta, The Sicilian Mafia The Business of…, 105

Categorization

• XREF: Directly extends my reading purpose: the dichotomous-violence logic explains why ONE supplier dominates — the private-enforcement monopoly that mirrors Milgrom’s single private judge. This is the micro-mechanism underneath Schelling’s credible-commitment account.
• DEEPTHINKING: The claim that toughness cannot be graded means the ‘protection’ commodity structurally forbids competitive equilibrium — a market where rational differentiation is impossible. The full argument (honor as variable-but-dichotomous reputation; zero-sum contests as advertising) resists one-line summary.
• DEFINE: Redefines mafia ‘honor’ as the reputation for supplying credible protection — usable, productive definitional content distinct from popular usage.
