This study explains the emergence of the Sicilian mafia in the XIX century as the product of the interaction between natural resource abundance and weak institutions. We advance the hypothesis that the mafia emerged after the collapse of the Bourbon Kingdom in a context characterized by a severe...

This paper investigates to what extent youth alcohol consumption depends on consumption patterns by other household members and on social interactions outside the household. Exploiting the richness of the data, we explore the possibility of asymmetric social influences by gender and by age, the...

Alcohol consumption may be associated to a rich social life, but its abuse might be related to a poor social life. This paper investigates whether alcohol consumption is a socially enjoyed good (a complement of social relations) or a substitute for social relations. In particular, it explores...

Social sanctions may be a strong deterrent of crime. This paper presents a formal model that relates crime and social sanction to social interaction density. We empirically test the theoretical predictions using a provincial level panel dataset on dierent crimes in Italy between 1996 and 2003....

We investigate the effects of civic norms and associational networks on crime rates. Civic norms may attach guilt and shame to criminal behavior, thus increasing its opportunity cost. Associational networks may increase returns to noncriminal activities and raise detection probabilities, but...
