In this paper we perform a statistical evaluation of whether it is worthwhile, in economic terms, to resist to extortion demands by the mafia, from the point of view of firms operating in an area dominated by criminal organizations. We use a unique collected and matched database on firm characteristics on the city of Palermo, highly controlled by the mafia racket. The underlined idea is that the claimed resistance has (direct and indirect) costs and benefits, so that a rational firm should take this decision according its economic expectations on the future profits (in addition to potential ethic considerations). It means that the economic policy messages of this experience can be linked to make more profitable the racket resistance (as a signal sent to the market). Our evidences based on multilevel discrete choice models show that this decision is strongly influenced by socio-economic characteristics of the district, type of activity involved and other factors.
