Testing descriptive social norm-nudges to increase flood preparedness among homeowners}, volume = {8}, journal = {Behavioural Public Policy}, number = {1}, publisher = {Cambridge University Press}, address = {Cambridge}, issn = {2398-0648}, doi = {https://doi.org/10.1017/bpp.2021.17}, pages = {121 -- 153}, year = {2021}, abstract = {Nudges based on social norms (norm-nudges) can be compelling behavioral interventions compared with traditional interventions such as taxes and regulations, but they do not work in all circumstances. We tested two empirical norm-nudge frames in an online experiment on taking measures for flood preparedness with large samples of homeowners (N = 1805) in two European countries, to evaluate the possible interactions between norm-nudge effectiveness, individual characteristics, and intercultural differences. We contrasted these norm-nudge treatments with a control and norm-focusing treatment by asking respondents to express their beliefs about what other respondents would do before making a decision relevant to their own payoff. We find no evidence of a treatment effect, suggesting that our social norm-nudges do not affect flood preparedness in the context of a flood risk investment game.}, language = {en} }
