The paper discusses distribution effects of extortion racket systems which are quite frequent in several countries and sometimes are responsible for an unexpectedly high proportion of the regional gross domestic product. The model presented here takes a system perspective, leaving individual decision making processes for further publications. It represents consumers, enterprises, criminals and the state and tries to determine under which conditions extortion racket systems come into being, survive, and can be successfully fought.

    This is justified by the fact that it is not uncommon in Italy that negative effects of criminal activities are compensated by payments from a funds of confiscated mafia assets. See Legge 181/2008, Art. 2 comma 7, Gazetta Ufficiale n. 268, 15/11/2008, according to which at least one third of all confiscated assets are transferred to two funds, the solidarity fund for extortion victims and the solidarity fund for victims of other mafia type crimes.
