We report results from an incentivized laboratory experiment to provide controlled evidence on the causal effects of alcohol consumption on risk preferences, time perception and altruism. Our design allows disentangling the pharmacological effects of alcohol intoxication from those mediated by...

Behind my reciprocation of a friend's gift may lie both instrumental reasons (I expect further future gifts) and `communicative' reasons (I want to establish or confirm a friendship per se). In a theory of rational individual action, such `communicative' reasons can be incorporated as an...

We develop a simple model of short- and long-term unemployment to study how labour market institutions interact with labour market conditions and personal characteristics of the unemployed. We analyze how the decision to exit unemployment and to mitigate human capital degradation by retraining...

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...

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...

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...

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 the 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...

In this paper, we investigate how government transparency depends on economic distortions. We first consider an abstract class of economies in which a benevolent policy maker is privately informed about the exogenous state of the economy and contemplates whether to release this information. Our...
