Measuring Heterogeneous Preferences for Adaptation Strategies in Response to Sea Level Rise: Evidence from Miami-Dade County
通过在线选择实验，研究了迈阿密-戴德县居民对三种海平面上升适应策略（建造海堤、补充海滩、安装雨水泵）的偏好，发现居民偏好额外的适应策略而非现状，且偏好与人口特征相关。
Despite mounting threats from rising sea levels, adaptation to sea level rise (SLR) is often challenged by limited funding and understanding of residents’ preferences. Using an online choice experiment, we investigate residents’ preference for three SLR adaptation strategies: building seawalls, replenishing the beach, and installing stormwater pumps in Miami-Dade County. We control the preference, scale, and alternative heterogeneity using generalized multinomial logit models with error components. Results show that residents prefer additional adaptation strategies to the status quo, and valuations of adaptation attributes are correlated with residents’ sociodemographics. Accounting for alternative heterogeneity also significantly improves model performance.
