Climate Change Impacts in Computable General Equilibrium Models: An Overview

17.08.2009 | HWWI Research Paper | von Sebastian Döll

This paper gives an overview about existing Computable General Equilibrium (CGE) models dealing with climate impacts focusing on damage calculations and adaptation modelling. Empirical CGE models are used in a broad field of policy analysis. With respect to climate change applications have been focused on the calculation of climate damages and the mitigation of these damages. Facing the non-preventable damages from climate change that occur already in the next decades adaptation is becoming a more important issue in the actual discussion. To our knowledge a model with explicit adaptation at the local level that includes socio-economic effects is missing. Such a regional model can analyse welfare effects where adaptation is implemented and therefore is important for political decision making.
