Abstract
Information campaigns that aim to encourage pro-environment activities are a widely popular policy instrument. In addition to closing the information gap related to target behaviours, such interventions can potentially change the beliefs that individuals hold about the appropriateness of these behaviours. This is particularly likely in the context of environment behaviours because of the normative nature of interventions, where a ‘correct’ behaviour is often encouraged. We look at whether individuals respond to information campaigns in the environmental domain because of their informational value or because they expect the campaign to change the social norm around these behaviours, and want to adhere to these new norms. We aim to separately identify these two channels through a field experiment.
