Thematic Guide to Integrated Assessment Modeling




The CONNECTICUT Model (Yohe and Wallace 1995) is a global model that combines elements of the probabilistic-scenario model of Nordhaus and Yohe (1983) and the DICE model (Nordhaus 1994). The model includes exogenously determined estimates of population and technological change while capital stock, fossil and nonfossil fuel consumption, and economic growth are determined endogenously. Uncertainties in key parameters are explicitly handled. The model has been used to assess optimal policy paths under the assumption that future revelation of non-market damages associated with a specified (but presently unknown) atmospheric-concentration threshold will motivate policy-makers to enact measures to ensure that the threshold is not passed.
