Total Demand Calculation
This Description function is used to mark the start of processing of the calculations of all demands and impacts.
It comprises the following functions:
Trigger Iterative Demand Calculation
This Join function is used to combine the View functions Iterate Over Demand Vector and Iterate Over Extended Demand Vector. This setup enables the calculation of all demands by only running this function.
Approximate Output Value
This Join function is used to aggregate outputs from tier 1, 2, ..., N that are stored in the Tier Demand Vector Model Table. The result is grouped by country/region, sector, impact type, data year, and scenario.
Approximate Extended Output Value
This Join function is used to aggregate outputs from tier 1, 2, ..., N that are stored in the Extended Tier Demand Vector Model Table. The result is grouped by country/region, sector, impact type, data year, and scenario.
Derive Induced Impact
This Join function is used to derive induced impacts from the results of the Approximate Output Value and the Approximate Extended Output Value functions. According to input-output analysis, the total impact of a company is a compilation of direct, indirect, and induced impacts generated in the economy as a result of the company’s activities. More specifically, if there is an increase in final demand of the company (for example, an increase in sales of the final goods), the direct impact would be the company’s increase in their outputs to meet the increased demand. Indirect impact is the change in demand on a company’s supply chain. Induced impact measures the effects of income being spent, as the household incomes throughout the economy change in response to the direct and indirect impacts (for example, increased employment).
In this sample content, induced impact is calculated before direct and indirect impacts by deducting the result of the Approximate Output Value function, which quantifies the direct and indirect impacts of corporate activities along the upstream value chain, from the result of the Approximate Extended Output Value function, which quantifies the sum of direct, indirect, and induced impacts.
