This paper gives an overview of the types of models available for analysing possible futures of the global economy. It then focuses on dynamic intertemporal general equilibrium models and describes how these models are used for both projections and scenario analysis. Some lessons from recent history both theoretical and practical are used to demonstrate the usefulness of the models.
[On the Global Climate Action Summit] I think that this summit’s been very useful. It’s a demonstration of activism, it’s a demonstration of will, it’s a demonstration of engagement by all sorts of sub-national players, and I think that’s all been tremendously useful. But, it doesn’t fill the gap of the absence of the United States at a national level. The US federal government can drive action all around the entire country, not just state-by-state.
