Should I Stay or Should I Go? The Impact of Natural Disasters and Regulation on U.S. Property Insurers’ Supply Decisions

In this article, we identify the main factors that drive insurers’ willingness to offer coverage in catastrophe‐prone property insurance lines. We compare insurers’ supply decisions in personal and commercial lines, with an emphasis on insurers’ responses in the aftermath of natural disasters. Our empirical results suggest important policy implications with regard to improving the availability of insurance against catastrophic threats. Concerning the impact of regulatory constraints, we present empirical evidence that certain regulatory responses may unintentionally impede insurers’ willingness to provide coverage against natural disasters.
