IAMs have been and will remain the workhorse models for climate economics and policy analysis. The smaller ones tend to be good for cost-benefit analysis but they are less good on sectoral, regional and geographical differences. The larger ones tend to include all the complexities, but they tend to be less transparent. As is the case with all models, the answers will be driven by the judgements that the modeller makes in developing the model.
Key learning objectives:
What are Abatements Costs?
What does the last component of an IAM model include?
