Integrating engineering outputs from natural disaster models into a dynamic spatial computable general equilibrium model of Centerville

A dynamic spatial computable general equilibrium (DSCGE) model is constructed that describes how engineering and economic models can be integrated to assess the economic, demographic, and fiscal impacts of disasters. This paper has two objectives. First, we introduce the DSCGE model and describe how it is calibrated specifically for Centerville. Second, to demonstrate the analytic flexibility of the DSCGE platform, we present economy-wide prompt effects from simulations involving spatially circumscribed shocks to Centerville's building portfolio and transportation infrastructure, and then detail dynamic economy-wide effects from simulations involving combinations of infrastructure damage and adjustments to the economic behavior of agents. We conclude with a discussion of the technical challenges ahead.
