The input-output calculation is an instrument for sectoral analysis and policy advice. With the input-output calculation, the economic structures of an economy can be examined and the effects of changes in wages, prices or demand on the economy as a whole or its sub-areas can be estimated in advance.
The sectoral consequences of economic control measures can also be recorded with this calculation method. It thus helps to answer important economic questions:
What is the economic importance of information and communication technology (ICT) goods in the economy as a whole?
How high are the job losses with falling construction investments?
What influence do more expensive oil imports have on the price development of certain industries or the overall economic price level itself?
The calculations are based on input-output tables, which provide a detailed insight into the direct but also indirect interrelationships between goods production and the flow of goods in the economy, including export and import.
