We study the long-run effects of contact with individuals from other regions in early adulthood on preferences, beliefs and national identity. We combine a natural experiment, the random assignment of male conscripts to different locations throughout Spain, with tailored survey data. Being...

We investigate how the intensity of Ramadan affects educational outcomes by exploiting spatio-temporal variation in annual fasting hours. Longer fasting hours are related to increases in student performance in a panel of TIMMS test scores (1995-2019) across Muslim countries but not other...
