Encyclopedia
Diego Gambetta is an Italian born social scientist
. He is a professor of sociology
at the University of Oxford
and an official fellow at Nuffield College. He is well known for his vivid and unconventional applications of economic theory and a rational choice approach to understanding a variety of social phenomena. He has made important analytical contributions to the concept of trust by using game theory and signalling theory
.
, where his doctoral supervisor was the late social statistician Cathie Marsh. He was first junior and then senior research fellow at King's College, Cambridge
, from 1984 to 1991. From 1995 until 2003 he was reader in sociology at the University of Oxford
and fellow of All Souls College. In 2003 he became professor of sociology and official fellow of Nuffield College. In 2000 he was elected a fellow of the British Academy
. He is also a Fellow of the European Academy of Sociology. He has held visiting positions at the University of Chicago, Columbia University, Sciences Po and Collége de France in Paris, and Stanford University.
Gambetta has a long lasting interest in trust. In 1987, when the concept was largely ignored in the social sciences, he published a ground breaking edited collection, with authors from all quarters of the social sciences (“Trust. Making and Breaking Cooperative Relations”). His subsequent work in this area, with the late economist Michael Bacharach, employs game theory
to provide a rigorous definition of trust, and signalling theory
to understand the nature of trust decisions. This work describes at once how trust can be threatened by “mimics” of signals of trustworthiness, and the general conditions under which signals of trustworthiness can be relied upon. Signalling theory, which emerged simultaneously in economics and biology in the early 1970s –asserts that the reliability of signals, in social interactions among humans and other animals, depends on whether the signals are supported by behaviour that would be too costly for (most) mimics to afford, while being affordable by genuine signallers.
After an imaginative application of the theory to how taxi drivers in dangerous cities decide whether to take on board hailers and callers on the basis of little information, Gambetta’s recent major work, “Codes of the Underworld. How Criminals Communicate” (published by Princeton University Press in 2009), applies signalling theory to analyze how credibility of communication is established in a world where trust is under multiple threats. Thomas Schelling
, the Nobel Prize
winning economist, among the first and few to write on the economics of organized crime, wrote that the book “illuminates a vast field of strategic communication where trust cannot be taken for granted. There is nothing comparable in print, and the book's interpretations will carry well beyond the field of conventional crime.” The book, listed by New Scientist as one of The best books of 2009, has been described by one reviewer as the product of a “brilliant economic naturalist.”
Gambetta’s work has, in recent years, extended to examining violent extremists. In 2005 he edited “Making Sense of Suicide Missions” (published by Oxford University Press), and he is now working with Steffen Hertog on a book on “Engineers of Jihad” for Princeton University Press.
In terms of direct intellectual influences on Gambetta’s work, in addition to Thomas Schelling, one may count Michael Bacharach, Partha Dasgupta, Jon Elster and Bernard Williams.

Analysis
In his book "The Sicilian Mafia: The Business of Private Protection" (published by Harvard University Press in 1993), he brings a new perspective on an extralegal institution like the Mafia by underscoring the market demand for protection that it satisfies and by showing how mafiosi’s apparently outlandish rituals and behaviours make organisational sense. His approach has had much influence on the study of mafia-like organisations around the world – it has been applied to cases in Russia, Hong Kong, Japan Bulgaria and Mainland China – and more generally on the study of extra-legal governance as well as Mafia Transplantation.Gambetta has a long lasting interest in trust. In 1987, when the concept was largely ignored in the social sciences, he published a ground breaking edited collection, with authors from all quarters of the social sciences (“Trust.
