Yet, many consumers have misconceptions about the environmental impacts of their diets and lack knowledge on how to prepare sustainable meals. This study uses a mixed-methods approach to develop four information nudges and to test their impact on dietary choices among a representative sample of Dutch consumers. A 2 2 between-subjects design crossing type of information (procedural versus declarative) with type of impacts (health versus environmental) is applied. The environmental impact is measured in terms of CO2 emissions, land use and water use. We find that pre-intervention knowledge about sustainable or healthy diets is related to the sustainability of participants' dietary choices. Procedural knowledge on how to prepare a healthier meal has the greatest potential to influence dietary behavior, in particular for participants without prior self-reported dietary restrictions.}, language = {en} } @article{MolBotzenBlasch2020, author = {Mol, Jantsje M. and Botzen, Wouter and Blasch, Julia}, title = {Behavioral motivations for self-insurance under different disaster risk insurance schemes}, volume = {2020}, journal = {Journal of Economic Behavior \& Organization}, number = {180}, publisher = {Elsevier}, address = {Amsterdam}, issn = {0167-2681}, doi = {https://doi.org/10.1016/j.jebo.2018.12.007}, pages = {967 -- 991}, year = {2020}, language = {en} } @article{MolBotzenBlaschetal.2020, author = {Mol, Jantsje M. and Botzen, Wouter and Blasch, Julia and de Moel, Hans}, title = {Insights into Flood Risk Misperceptions of Homeowners in the Dutch River Delta}, volume = {40}, journal = {Risk Analysis}, number = {7}, publisher = {Wiley-Blackwell}, address = {Oxford}, issn = {1539-6924}, doi = {https://doi.org/10.1111/risa.13479}, pages = {1450 -- 1468}, year = {2020}, abstract = {Flooding is one of the most significant natural disasters worldwide. Nevertheless, voluntary take-up of individual damage reduction measures is low. A potential explanation is that flood risk perceptions of individual homeowners are below objective estimates of flood risk, which may imply that they underestimate the flood risk and the damage that can be avoided by damage reduction measures. The aim of this article is to assess possible flood risk misperceptions of floodplain residents in the Netherlands, and to offer insights into factors that are related with under- or overestimation of perceived flood risk. We analyzed survey data of 1,848 homeowners in the Dutch river delta and examine how perceptions of flood probability and damage relate to objective risk assessments, such as safety standards of dikes, as well as heuristics, including the availability heuristic and the affect heuristic. Results show that many Dutch floodplain inhabitants significantly overestimate the probability, but underestimate the maximum expected water level of a flood. We further observe that many respondents apply the availability heuristic.}, language = {en} } @article{MolBotzenBlaschetal.2021, author = {Mol, Jantsje M. and Botzen, Wouter and Blasch, Julia and Kranzler, Elissa C. and Kunreuther, Howard C.}, title = {All by myself?

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} }
