Identifying Agglomeration Shadows: Long-run Evidence from Ancient Ports
écrit avec R. Hornbeck and G. Michaels
We examine "agglomeration shadows" that emerge around large cities, which discourage some economic activities in nearby areas. Identifying agglomeration shadows is complicated by endogenous city formation, however, and a "wave interference" that we show in simulations. We use the locations of ancient Mediterranean ports, which seeded modern cities, to estimate shadows cast on nearby areas. These patterns extend to modern city locations, more generally, and illustrate how encouraging growth in particular places can discourage growth of nearby areas.

News, emotions, and policy views on immigration
How do emotions affect policy views on immigration? How do they influence the way people process and respond to factual information? We address these questions by using a survey experiment in Italy, which randomly exposes around 7,000 participants either to (i) sensational news about immigrant crimes, (ii) statistical information about immigration, (iii) or to the combination of both. First, we find different effects of news depending on the emotional load of the reported crime: while the news of a rape against a young woman significantly increases the demand for anti-immigration policies, there is no impact of the news of a petty theft. Consistent with a causal role of emotions, we find that the rape news triggers a stronger emotional reaction than the theft news, while having the same effect on factual beliefs. Second, we document that information provision corrects factual beliefs, irrespective of whether participants are also exposed to the rape news. Yet, the exposure to the rape news strongly influences whether belief updating translates into change in policy views: when presented in isolation, information tends to reduce anti-immigration views; when combined with the rape news, the impact of the latter dominates and participants increase their anti-immigration views to the same extent as when exposed to the rape news only. This evidence suggests that, once negative emotions are triggered, having more accurate factual knowledge no longer matters for forming policy views on immigration.
