Machine Learning Enabled Computable General Equilibrium (CGE) - Salt Lake City

Machine Learning Enabled Computable General Equilibrium (CGE) - Salt Lake City#

Description

The “Machine Learning Enabled Computable General Equilibrium (CGE) - Salt Lake City” analysis merges advanced machine learning with traditional CGE models to offer unprecedented insights into the economic impacts of disaster scenarios on Salt Lake City. Trained on a comprehensive dataset of numerous simulated disasters and their economic effects, this hybrid approach excels in predicting the intricate dynamics of the city’s economy under various crises.

A computable general equilibrium (CGE) model is based on fundamental economic principles. A CGE model uses multiple data sources to reflect the interactions of households, firms, and relevant government entities as they contribute to economic activity. The model is based on (1) utility-maximizing households that supply labor and capital, using the proceeds to pay for goods and services (both locally produced and imported) and taxes; (2) the production sector, with perfectly competitive, profit-maximizing firms using intermediate inputs, capital, land, and labor to produce goods and services for both domestic consumption and export; (3) the government sector that collects taxes and uses tax revenues in order to finance the provision of public services; and (4) the rest of the world.

The output of this analysis are CSV files with domestic supply, gross income, before- and post-disaster factor demand and household count.
