Social closure, surnames and crime

Abstract

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 shows that, all else equal, communities with a history of social closure have lower crime rates and higher tax evasion rates than more open communities. The effect of social closure is likely to be causal, it is relevant in magnitude, statistically significant, and robust to changes in the set of included controls, in the specific measures of dependent and independent variables, in the specification of the regression equation, and in the possible sample splits. Our findings are consistent with the idea that social closure strengthens social sancions and social control, thus leading to more cooperative outcomes in local interactions, but it reduces cooperation on a larger scale.

Kinship, Fractionalization and Corruption

“…26 One further implication of our theory that our current data does not allow us to test is that local crime, in which neighbors are targets, should be less common in regions with high consanguinity rates. Buonanno and Vanin (2015) provide related evidence consistent with our findings and with this hypothesis as well. Using the distribution of surname frequencies from Italian phonebooks, they show that municipalities with more surname concentration (i.e.…”

Profiling Crime in Pakistan: An Aggregated and Disaggregated Socioeconomic Analysis

“…As the population density increases the competition among people over basic needs and economic opportunities thus evoke the crimes. Moreover, higher population growth can make it difficult for the administration to provide all the facilities as well as social security to mass of population leads to increase in illegal activities (Buonanno and Vanin, 2017;Ishak and Bani, 2017;Jendryke and McClure, 2019;Mellgren, Pauwels, and Levander, 2010;Umair, 2019).…”

Earthquake Hazard and Civic Capital

“…In line with previous literature, we focus on several dimensions of pro-social behavior conducive to the accumulation of civic capital (Putnam, 1993). Specifically, we consider: (i) the presence of an organ donation association, to assess the purely altruistic component of prosociality (Guiso et al, 2011); (ii) a measure of tax compliance as a proxy of individual willingness to free ride on contribution to a public good (Buonanno and Vanin, 2017); and (iii) the density of Catholic churches as a reflection of the religious-driven component of civic capital (Sinding Bentzen, 2019;Paldam and Paldam, 2017). As our measures of civic capital may be affected by other variables that are also correlated with earthquake hazard, we add a rich set of control variables to our estimates, including climatic, geographic, and historical information about each municipality.…”

“…This data allows us to build a measure of local fiscal compliance (Tax compliance). That is, for each municipality, the share of households paying the annual licensing fee (Buonanno and Vanin, 2017;Buonanno et al, 2019), as reported by the Italian national public broadcasting company (RAI -Radiotelevisione Italiana). This information is a valid proxy of fiscal compliance for several reasons.…”
