Abstract

This paper studies the impact of disaster experiences on communities' engagement in risk mitigation actions, focusing on flooding in the United States. We measure risk mitigation actions using communities' scores in the Community Rating System, an incentive program that scores flood preparedness and mitigation activities and rewards communities with flood insurance premium discounts. Leveraging a panel of communities from 1998 to 2019, we find a significant increase in risk mitigation activities following flood events, in both participation rates and intensity of actions. The effects continue to increase up to 10 years. Communities with greater capacity, particularly those in urban areas, exhibit a much stronger response. The findings highlight the adaptive capacity of communities but also raise several concerns regarding the inefficiency of disaster-driven responses and inequitable outcomes across communities.

减轻风险行动中的社区对洪水的反应:来自社区评级系统的证据
本文研究了灾害经历对社区参与风险缓解行动的影响,重点是美国的洪水。我们使用社区评分系统中的社区评分来衡量风险缓解行动,这是一个奖励计划,对洪水准备和缓解活动进行评分,并以洪水保险保费折扣奖励社区。利用1998年至2019年的社区小组,我们发现洪水事件后的风险缓解活动在参与率和行动强度方面都有显着增加。其影响持续增加至10年。能力较强的社区,特别是城市地区的社区,反应要强烈得多。研究结果强调了社区的适应能力,但也提出了一些关于灾害驱动的反应效率低下和社区间不公平结果的担忧。
