The input-output model (Leontief model) was used to analyse the economic impact of PSE activities. By using it, the impact of PSE's activities was calculated in three categories:
- Generated added value
- Remuneration
- Employment.
For each of the categories listed, the impact of PSE was shown in three dimensions:
- Direct effect – resulting from PSE's core business,
- Indirect effect – generated among suppliers and entities from related industries,
- Induced effect – further growth generated due to household revenue growth.
In this year's report, similarly to the previous year, in addition to the impact of operations, the impact of capital expenditures (CAPEX) was calculated. Investment demand is the component of final demand in the economy that provides the momentum for global output. Using Leontief's model, input-output multipliers were calculated to show how an increase in final demand translates into an increase in global output.
