A computable general equilibrium model was made to study how climate and trade policies affect the economy. This model looks at how prices in different markets connect and how people spend their money, showing the big picture of how policies can impact the whole economy, not just specific parts. By using this model, experts can see how policy changes can affect resources and people's incomes all across the economy. This type of model is commonly used to see how climate and trade policies affect the economy as a whole.
