The role of ethnic immigrant networks in facilitating international trade is a well-established phenomenon in the literature. However, it is less clear whether this relationship extends to illegal trade and unauthorized immigrants. In this paper, we tackle this question by focusing on the case...

Greek-letter student social groups, better known as fraternities and sororities, are a ubiquitous feature on many American higher education campuses. These organizations, especially fraternities, have a reputation for encouraging unruly and improper behavior among both members and non-members....

Recent years have seen a rise in mass shooting incidents in the United States. While direct victims and their families undoubtedly suffer the most serious consequence of mass shootings, little is known on whether mass shootings have negative impacts beyond those immediately exposed to the...

In this paper, I assess the causal effects of judicial administration on a sample of Italian criminal firms in the period 2004-2016, to shed light on the dynamic path of the firm's performance from pre-seizure to the post-entry judicial administration phase. By using exogenous enforcement law...
