Application
Before a model is built, its structure has to be decided. eModeler helps economists design it from the national accounts, the Social Accounting Matrix and the policy questions the government needs answered.
What it is
Every economic model rests on design choices: which sectors to separate, how to group the rest, which accounts to represent and which indicators to produce. Getting these wrong means a model that cannot answer the questions it was built for — or that the data cannot support.
eModeler guides these choices. It starts from the national accounts and the Social Accounting Matrix, respects the sector aggregation available in official government data, and shapes the model around the indicators to monitor and the policies being tested.
How it works
01
The national accounts and the Social Accounting Matrix set out what the economy looks like and what data exist.
02
Sector aggregation follows what is available in official government data, so the model stays consistent with national statistics.
03
The indicators the government needs to monitor or test determine what the model must produce.
04
The structure is matched to the policies under consideration, so the finished model can answer the questions that matter.
What goes into the design
01
How each product is used — by production, investment, households, exports, government and changes in stocks — split into basic flows, margins and taxes, together with payments to labour, capital and land, production taxes and other costs.
02
Which economic activities to model separately. Official data may distinguish, for example, 26 activities — from agriculture, petroleum, gas and refining to the Suez Canal, tourism, financial services and government services.
03
How consumption is broken down — for example, 15 spending categories from food, housing and transport to health and education, including in-kind transfers such as ration cards and bread subsidies.
