Measuring Heterogeneous Preferences for Adaptation Strategies in Response to Sea Level Rise: Evidence from Miami- Dade County

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 inves-tigate residents' preference for three SLR ad-aptation strategies: building seawalls, replen-ishing the beach, and installing stormwater pumps in Miami -Dade County. We control the preference, scale, and alternative heteroge-neity 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 resi-dents' sociodemographics. Accounting for al-ternative heterogeneity also significantly im-proves model performance. (JEL Q51, Q54)
