Bowling Alone, Drinking Together

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 whether the answer changes between use and abuse, beer, wine and spirits, youth and adults, controlling or not for family influence and unobserved heterogeneity, and for various forms of social relations. Controlling for a great number of covariates and allowing for non linear and identity-specific family interaction effects, we find that alcohol consumption is a socially enjoyed good.Social relations, Social interaction, Family, Alcohol consumption, Binge drinking

”Thou shalt not covet ...”: Prohibitions, Temptation and Moral Values

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 the model to crime and study the conditions under which agents would optimally adhere to moral values of honesty. Incentives to be moral are non- monotonic in the crime premium. Larger external punishments increase temptation and demand for morality, so that external and internal sanctions are complements. The model helps rationalizing stylized facts that proved difficult to explain with available theories.Prohibitions, Temptation, Self-Control, Moral Values, Crime

Competition, Reputation and Compliance

This paper displays a linear demand oligopoly model, in which firms endogenously decide whether to enter the market and whether to specialize on high or low quality products, and then repeatedly interact to sell experience goods. It shows that the intuition that low and rising prices grant compliance with quality promises extends to this setting, provided that high quality is sufficiently important to buyers

On the historical and geographic origins of the Sicilian mafia

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 development of a florid market for private protection and the emergence of a cartel of protection providers: the mafia. This would especially be the case in those areas (prevalently concentrated in the Western part of the island) characterized by the production and commercialization of sulphur and citrus fruits, Sicily's most valuable export goods whose international demand was soaring at the time. We test this hypothesis combining data on the early incidence of mafia across Sicilian municipalities and on the distribution of sulphur reserves, land suitability for the cultivation of citrus fruits, distance from the main commercial ports, and a variety of other geographical controls. Our empirical findings provide support for the proposed hypothesis documenting, in particular, a significant impact of sulphur extraction, terrain ruggedness, and distance from Palermo's port on mafia's early diffusion.Organized crime, Mafia, Private protection, Persistence, Trade shocks, Sulfur, Citrus fruits

Social Closure, Surnames and Crime

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

Government Information Transparency

This paper studies a model of announcements by a privately informed government about the future state of the economic activity in an economy subject to recurrent shocks and with distortions due to income taxation. Although transparent communication would ex ante be desirable, we find that even a benevolent government may ex-post be non-informative, in an attempt to countervail the tax distortion with a "second best" compensating distortion in information. This result provides a rationale for independent national statistical offices, committed to truthful communication. We also find that whether inequality in income distribution favors or harms government transparency depends on labor supply elasticity.Government announcements, Cheap talk, Asymmetric in- formation, Inequality

Participation, growth and social poverty: social capital in a homogeneous society

We introduce social capital accumulation into a neoclassical model, showing how it differs from physical and human capital accumulation. We take the view that social capital is crucial to the enjoyment of socially provided goods and that it is mainly accumulated by means of participation to social activities. Under-investment in social capital maylead a growing economy to fall into a social poverty trap. We argue that this risk is particularly relevant for advanced societies.Social capital; self-protection choices; social poverty traps

Economic Growth and Social Poverty: The Evolution of Social Participation

We develop an evolutionary model of growth in which agents choose how to allocate their time between private and social activities. We argue that a shift from social to private activities may foster market-based growth, but also generate social poverty. Within a formal framework that merges a game theoretic analysis of the evolution of social participation with a model of dynamic accumulation of its effects on social environment (i.e., of social capital accumulation), we show that growth and well-being may evolve in opposite directions (a plausible outcome for advanced and affluent societies).Time Allocation, Social Capital, Relational Goods

Social capital accumulation and the evolution of social partecipation

We study the co-evolution of social participation and social capital accumulation, taking the view that the former contributes to the latter, and both contribute to the enjoyment of relational goods Within this framework, we show that a process of substitution of private for social activities (observable in some advanced, affluent economies), might be self-reinforcing and lead to a Pareto-dominated steady state. We find some scope for policy intervention, but we also acknowledge its difficulty.Social Capita; Well-being; Time Allocation

Organized Crime and Electoral Outcomes in Sicily

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 disaggregated data from the Italian region of Sicily, that between 1994 and 2008 Silvio Berlusconi’s party, Forza Italia, obtained higher vote shares in municipalities plagued by mafia. The result is robust to the use of different measures of mafia presence, both contemporary and historical, to the inclusion of different sets of controls and to spatial analysis. Instrumenting mafia’s presence by determinants of its early diffusion in the late XIX century suggests that the correlation reflects a causal link, which would be coherent with mafia’s choice to back Forza Italia in exchange for favorable policies
