The hedonic pricing approach is used to examine whether homeowners and/or renters alter their subjective assessments of earthquake risks after massive earthquakes. Using nation-wide household panel data coupled with earthquake hazard information and records of observed earthquakes, we find that there are some modifications of individuals' assessments of earthquake risk in both cases. We have carefully taken into consideration the bias stemming from the use of objective risk variables as a proxy for individual risk assessments. Our results suggest that the price discount from locating within a quake-prone area is significantly larger soon after earthquake events than beforehand. We argue that the most likely interpretation for this result is that households tend to underestimate earthquake risk if there has not been a recent occurrence.

A theoretical framework and empirical evidence are presented to show the connection between community uniform rating and cross-subsidies in earthquake insurance policy in Japan.Cross-subsidies are defined as the difference between a fair actuarial premium and the community uniform rate. The estimation result shows that the uniform community rating may unintentionally cross-subsidize inhabitants in high risk areas at the expense of inhabitants in low risk areas. Our simulation results indicate that replacing the current community rating with the fair actuarial premium would increase the overall subscription rate for earthquake insurance by about 3.7 percentage point, and that the increase is particularly prominent in relatively less risky areas. We propose modifying the Japanese earthquake insurance system by adopting a more refined risk rating system that more closely reflects regional differences in earthquake risk.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
