ABSTRACT

Cedar Rapids, IA, offers a unique case study in planning for increased resilience. In 2008, Cedar Rapids experienced severe flooding. Rather than simply rebuilding, the city of Cedar Rapids began to invest in a resilient flood control system and in the revitalization of its Downtown neighborhood. This paper develops a Computable General Equilibrium (CGE) model for the regional economy of Cedar Rapids to quantify ‘resilience dividends’: net co-benefits of investing in increased resilience. A resilience dividend includes benefits to the community even if another disaster does not occur. We build a CGE model of Cedar Rapids at two different time periods: one in 2007, before the flooding, and one in 2015, after the flooding and initial investment in resilience. We show that a positive economic shock to the economy results in larger co-benefits for key economic indicators in 2015 than in 2007. Our approach illustrates how co-benefits are distributed throughout the economy.

摘要

爱荷华州锡达拉皮兹提供了一个独特的案例研究，用于规划提高弹性。2008 年，锡达拉皮兹遭遇了严重的洪水。锡达拉皮兹市不是简单地重建，而是开始投资于弹性防洪系统和市中心社区的振兴。本文为锡达拉皮兹的区域经济开发了一个可计算的一般均衡 (CGE) 模型，以量化“弹性红利”：投资于增加弹性的净协同收益。即使没有发生另一场灾难，复原力红利也包括对社区的好处。我们在两个不同的时间段建立了 Cedar Rapids 的 CGE 模型：一个是在 2007 年，洪水之前，另一个是在 2015 年，在洪水和初始弹性投资之后。
