In 2005 an earthquake in northern Pakistan led to a significant inflow of international relief groups. Four years later, trust in Europeans and Americans was markedly higher among those exposed to the earthquake and the relief that followed. These differences reflect the greater provision of foreign aid and foreigner presence in affected villages rather than preexisting population differences or a general impact of disasters on trust. We thus demonstrate large-scale, durable attitudinal change in a representative Muslim population. Trust in Westerners among Muslims is malleable and not a deeply rooted function of preferences or global (as opposed to local) policy and actions.

We study the impact of providing school report cards with test scores on subsequent test scores, prices, and enrollment in markets with multiple public and private providers. A randomly selected half of our sample villages (markets) received report cards. This increased test scores by 0.11 standard deviations, decreased private school fees by 17 percent, and increased primary enrollment by 4.5 percent. Heterogeneity in the treatment impact by initial school test scores is consistent with canonical models of asymmetric information. Information provision facilitates better comparisons across providers, and improves market efficiency and child welfare through higher test scores, higher enrollment, and lower fees.
