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 proposes a theory of the relationship between prohibitions and temptation. In presence of self-control problems, moral values may increase individual material welfare (and utility) by serving as a self-commitment device. The model investigates the relationship between morality and...

This research attempts to explain the large differences in the early diffusion of the mafia across different areas of Sicily. We advance the hypothesis that, after the demise of Sicilian feudalism, the lack of publicly provided property-right protection from widespread banditry favored the...

This paper investigates the relationship between mafia and politics by focusing on the market for votes. It exploits the fact that in the early 1990s the Italian party system collapsed, new parties emerged and mafia families had to look for new political allies. It presents evidence, based on...

This paper studies the effect of social closure on crime and tax evasion rates using disaggregated data for Italian municipalities. It measures the degree of social openness of a community by the diversity of its surname distribution, which reflects the history of migration and inbreeding. It...

Beyond direct damages, terrorism creates fear and insecurity, potentially reducing support for democratic institutions if these are deemed inadequate to tackle the threat, and increasing support for military governments. To investigate this possibility, we use data from Pakistan, a country that...

An argument against the legalization of the cannabis market is that such a policy would increase crime. Exploiting the recent staggered legalization enacted by the states of Washington (end of 2012) and Oregon (end of 2014) we show, combining difference-in-differences and spatial regression...

We provide first-pass evidence that the legalization of the cannabis market across US states may be inducing a crime drop. Exploiting the recent staggered legalization enacted by the adjacent states of Washington (end of 2012) and Oregon (end of 2014) we find, combining county-level...

We propose a theory studying temptation in presence of both externally and internally sanctioned prohibitions. Moral values that (internally) sanction prohibited actions and their desire may increase utility by reducing self-control costs, thereby serving as partial commitment devices. We apply...
