Abstract: | Household flood risk mitigation is an important component of Integrated Flood Risk Management. Voluntary household decisions about whether or not to structurally mitigate or insure can directly and indirectly influence vulnerability to the flooding of a community. Serious games can augment existing data collection methods in the flood risk context by operating in the space in between stated and revealed preference, through observing decisions as opposed to asking abstract hypothetical questions, while allowing for complete control over experimental conditions. We look to answer the question of which individual and contextual factors contribute to the decision to mitigate against floods. We gather household decision-making data using a serious game role-play experiment named the Decision Game. Participants spent about 20 minutes making decisions about where to live and how to distribute limited income, given geographical information, including flood risk, about the city. We use a generalized linear mixed modelling approach to analyze the data. Among other findings, we see that experiencing an in-game flood had a strong positive effect, compared to a much weaker effect of a participant having experienced a real-life flood; our key observation is that incentivizing flood risk mitigation should be done quickly following a flood event. We find that real-life low-income individuals were no less likely to implement in-game mitigation measures than their higher-income counterparts, suggesting that subsidies to address an income barrier may be an effective method of encouraging low-income household mitigation. We apply the model to a case study of Calgary, Alberta finding that the insurance market could maintain cross-subsidization after a flood, making insuring higher risk areas more feasible. Moreover, we find that Calgarian policymakers should be encouraged to limit subsidy coverage to high-risk areas to avoid inefficient use of funds in low-risk areas which were projected to have the clear majority of program uptake. |
