Introduction to the Database in a CGE Model (2 minute read)
View
The database of a CGE model has two components. One is the Social Accounting Matrix, or
SAM. The SAM describes all the
transactions in an economy at a point in time, usually a year. It displays these data in a logical format,
with rows and columns showing how transactions among agents and other accounts link all parts of the economy in a circular flow of income and spending.
The second part of a CGE database is the set of elasticity parameters that describe the responsiveness of producers and consumers to changes in their income or prices.
