Abstract: Italy’s anti-Mafia legislation allows confiscated Mafia properties to be converted into educational, cultural, and welfare facilities where local NGOs offer various social activities specifically targeting youth and other vulnerable groups. This study provides the first causal estimation of how exposure to these repurposed spaces affects students’ dropout rates by changing their attitudes toward educational and criminal pathways. Using school-level geo-referenced data from 2015 to 2022 and exploiting the staggered timing of property reuse, I investigate changes in local dropout rates. Results reveal a significant reduction in dropout rates of approximately 34% relative to the mean for students near repurposed properties. I show that these facilities reshape students’ beliefs, reducing the appeal of Mafia networks while increasing the value of formal education. The effects are not explained by gentrification, additional educational support, or civic engagement levels.

Abstract: Policies expanding police discretionary authority are widespread and politically contested, yet their effects on police behaviour, institutional trust, and political preferences remain poorly understood. We study Britain’s 2014 Anti-Social Behaviour, Crime and Policing Act, which authorised local councils to implement Public Space Protection Orders (PSPOs), prohibiting broadly defined anti-social activities and expanding officer discretion in designated areas. Using the first comprehensive dataset on PSPO implementation across London census tracts (2016–2024), linked to crime records, stop-and-search data, and electoral outcomes, we exploit PSPOs’ staggered adoption to identify causal effects. These policies increase unproductive police stop-and-search activity, disproportionately targeting non-white residents. Reported anti-social behaviour and other crimes remain unaffected. These findings suggest that vaguely defined discretionary enforcement tools can generate racially unequal policing without delivering the public order benefits that justify their adoption.

Abstract: Violence is often viewed as an intrinsic feature of illicit markets, driven by competition, disputes, and predation. We argue that the connection between violence and markets is not exclusive to illicit markets and that in the absence of strong institutions these factors exist ubiquitously. Using an estimator of spatial concentration, we document the empirical relationship between violence and markets in the 14th century. We then employ a large language model to analyze the coroner’s accounts of the era’s homicides, finding that many of these incidents were driven by avoidable business-related disputes. Employing a novel difference-in-differences estimator for spatial concentration, we proceed to causally identify the impacts of the introduction of London’s first professional police force in the 19th century on this concentration. We find that the police force’s introduction led to a 54% reduction in the degree of concentration of violence around marketplaces. Our findings suggest that it is not the nature of the commodities being sold in illicit markets that drives violence, but is rather the absense of formal institutions of enforcement and dispute resolution

Abstract: Mafia groups have been developing their power and local control over Sicily since the 19th century by enforcing an alternative institutional system with its own laws. In this paper, we test the historical effect of the Mafia on the legal judiciary as an alternative mechanism of conflict resolution. Under an IV approach, we find that the presence of the Mafia reduces the number of lawyers and the number of civil sentences at the tribunal level.
