Computable General Equilibrium (CGE) is an economic model used to analyze how changes in economic policy or other economic factors will affect the overall economic system. CGE models are used to understand how economic policies like taxes, subsidies, and tariffs affect the market, how government policies affect consumer spending, and how changes in the economy affect different parts of the population. CGE models are based on the idea that the economy is a dynamic system of interconnected markets, and that changes in one part of the system can have ripple effects in other parts. CGE models are often used to examine the macroeconomic effects of policy changes, but they can also be used to analyze the impacts of changes in other factors such as technology, consumer preferences, and the environment.
