An examination of market efficiency around hurricanes
Authors:Reinhold P Lamb
Institution:Belk College of Business Administration University of North Carolina at Charlotte
Abstract:Hurricane Andrew produced more than $21.5 billion in property damage in Florida and Louisiana. Hurricane Hugo caused about $7 billion in damage in North and South Carolina. Although both hurricanes were large, the magnitudes of their destruction and the geographic concentrations of their paths were markedly different. This study finds that Hugo and Andrew produced substantially different market reactions on property and casualty (P&C) firms. The industry was generally unaffected by Hugo, regardless of whether or not firms had exposure in the Carolinas. Andrew, on the other hand, generated a significant negative impact on firms with exposure in Florida or Louisiana. Other firms were not effected by Andrew. These observations indicate that the market demonstrated an ability to discriminate by the magnitude of hurricane and by P&C firms based on their degree of loss exposure.
