Climate Shocks, Cyclones, and Economic Growth: Bridging the Micro-Macro Gap -- by Laura Bakkensen, Lint Barrage

Empirical analyses of the impacts of climatic shocks on growth, while critical for policy, have found seemingly disparate results and are seldom incorporated into macroeconomic climate-economy models. This paper seeks to bridge this micro-macro gap through the case of tropical cyclones. We first present a stochastic endogenous growth model that can reconcile previous empirical findings. We then empirically estimate the impacts of cyclones on the structural determinants of growth (total factor productivity, depreciation, fatalities), instead of growth itself, facilitating direct inclusion into the seminal DICE climate-economy model. Cyclone damages are estimated to increase the social cost of carbon by 10-15%.
