What is Input-Output?
The Input-Output framework of the European System of Accounts (ESA 1995) consists of three types of tables:
- Supply Tables,
- Use Tables and
- Symmetric Input-Output Tables.
The Tables provide a complete picture of the flows of goods and services (products) in the economy for a given year. They detail the relationship between producers and consumers and the interdependencies of industries.
Supply and Use Tables are constructed directly from survey and other data sources. The Supply Table provides estimates of the output of a large number of differentiated products by each industry and the Use Table provides estimates of the inputs (of goods and services) used by each industry to produce their own output.
The Supply and Use Tables are the basic building blocks; all other Input-Output analyses are derived from them.
Symmetric Tables (a.k.a. the Analytical Tables) represent the modelling aspect of the Input-Output framework. The Scottish Government produces annual Industry by Industry, Product by Product and Leontief Inverse Analytical Tables.
