摘要

本文利用 Facebook 社交连接指数（Social Connectedness Index，SCI）构建的社交网络邻接矩阵，研究了社交学习是否促进了气候风险感知的更新，从而为气候适应提供信息。我们发现，飓风哈维和艾尔玛引发的地区性洪水增加了全国范围内的洪水保险保单，其程度与各县与洪水地区的社交网络邻近程度相当，同时气候风险认知也得到了相应的更新。社会学习使洪水淹没的县在 3 年内增加了 25 万份保单，未淹没的县增加了 8.1 万份保单。我们发现了突出效应的证据，但不支持逆向选择或过度保险。

Social learning about climate risks

With a social network adjacency matrix constructed from the Facebook Social Connectedness Index (SCI), this paper examines whether social learning facilitates climate risk perception updates to inform climate adaptation. We find that Hurricanes Harvey and Irma-induced regional flooding increased flood insurance policies nationwide to the extent of each county's social network proximity to the flooded areas, with a corresponding update in climate risk perception. Social learning resulted in an additional 250,000 policies in flooded counties and 81,000 policies in unflooded counties over 3 years. We find evidence of the salience effect but no support for adverse selection or over-insurance.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
