摘要：

Public provision of environmental information is becoming prevalent worldwide to promote public awareness of environmental risks to protect health, but there is a lack of causal evidence on its effectiveness. This study examines how the provision of air quality information affects the behaviors, wellbeing, and academic performance of students in China. We conduct a large-scale experiment which randomly selects students in Chinese schools into multiple information interventions. The interventions include information on ambient air pollution and its impacts, advisories on defensive measures against air pollution and the potential effects. We find significant increases in defensive measures among students due to the advisories, particularly for the adoption of air purifiers in response to the adverse impact of air pollution on test scores. Remarkably, air purifier adoption further improves the mental health and test scores of students. The results provide novel and useful insights into information provision, risk perceptions and behaviors, and highlight the importance of tailored behavioral advisories in ensuring the effectiveness of information programs on air pollution and beyond.
