🔄 Vierdimensionale Input-Output-Modelle

The sub-topic Four-dimensional input-output models covers input-output models that map the interdependencies between both commodities and sectors. The corresponding calculation tool consists of five parts:

-General four-dimensional model

-Hierarchical structure (different modeling approaches involving commodity and sector structures on the input and output sides)

-Partial input-output tables (split into two commodity groups)

-Make-use matrices (a practical approach for constructing a commodity-based static input-output model)

-Derivation of the physical interdependency balance from a four-dimensional input-output model

The Documents & Materials section contains a mathematical description of the calculation tool and a collection of exercises.
