The CSERGE Model

The CSERGE (Center for Social and Economic Research into the Global Environment) Model, currently under development at the University College of London, is a global dynamic non-linear optimization model designed to determine the optimal level of greenhouse gas emissions reductions from abatement cost and damage functions (Maddison 1994a; 1994b). The marginal cost of emissions reductions (obtained from the shadow price) are a resultant of the model, which can be used to assess the desirability of alternative policies to reduce emissions. Uncertainty is treated in the model through the use of two point probability distributions on population, labor productivity, abatement costs, damages, and climate.

The CSERGE model was used in two recent studies. One compares the costs and benefits resulting from a policy to slow climate change (Maddison 1994b). The other looks not only at the cost-effectiveness of greenhouse gas emissions reduction policies, but also at the economic value of sulfur emissions due to their associated cooling effects (Maddison 1994a).
