Expanding the National Flood Insurance Program to allow policyholders to purchase optional erosion coverage eliminate coverage disputes when erosion and flood both contribute to a loss, and provide affordable national erosion coverage. We examine the household welfare effect of multi-peril hazard insurance coverage by coupling information on NFIP policy in force with a survey data for a sample of coastal households in the US southeast. Our results indicate that the value of multi-peril hazard insurance is substantially higher for households who live in the coastal zone. We also test effect of risk perception (subjective risk assessment) on individuals’ decision to purchase multi-peril hazard insurance and find that higher risk perception lead to higher probability of purchasing multi-peril insurance coverage and increases the mean willingness to pay for insurance
