Community traumatic events such as mass shootings, terrorist attacks, and natural or man-made disasters have the potential to disrupt student learning in numerous ways. For example, these events can reduce instructional time by causing teacher and student absences, school closures, and...

This paper uses variation in victimization probabilities between individuals living in the same community to shed new light on the costs of crime. I use panel data from the Mexican Family Life Survey for 2002 and 2005 and look at the impact of within-community differences in victimization risk...

This paper uses microdata from Brazilian natality and mortality vital statistics between 2000 and 2010 to estimate the impact of in-utero exposure to local violence – measured by homicide rates - on birth outcomes. The estimates show that exposure to violence during the first trimester of...
