We conduct a field experiment to study information transmission from children to their parents. We aim to promote the usage of an alcohol-based hand sanitizer, by teaching children its benefits and then test whether (i) information has been transmitted and (ii) information has an impact on the decision to purchase the hand gel. Moreover, in addition to a lecture on the benefits of the hand gel, our intervention implements a hands-on experience where children actually use the hand gel. We show that the average treatment effect of our intervention is positive on parents’ information, thus information is transmitted. Moreover, we use an instrumental variable approach to show that higher information implies a higher probability to purchase more hand gel.
