  • We study the influence of social messages encouraging the use of a Corona Tracing App, varying whether there is a message and if so, at what cost it came. Does this affect messaging behavior and norm expectations in receivers? The data show that willingness to invest in sending social messages increases in receivers. In contrast, norms remain largely robust. App-use and vaccine decisions of Corona patients are considered normatively relevant. This is reflected in norms regarding triage and sharing costs of Corona treatment. Yet social messages do not affect these norm expectations.
