What is CGE?

CGE offers a flexible and robust framework to quantify and explain how the economy evolves in response to those changes. Today, it has become an analytical tool widely used to inform on a large number economic issues.

CGE stands for computable general equilibrium. It is one of the most rigorous quantitative analytical tools for evaluating economy-wide impacts of economic policy reforms.

It is a class of economic models, largely built on neoclassical assumptions, hence the name general equilibrium.

For example:

How would the New Zealand economy respond to a fiscal stimulus?

What would be the impact on the economy if exports from the primary sector are doubled (MPI goals)?
