The Leontief Input-Output Model can be described by the equation X = AX +D where X is the production matrix (total output), A is the input-output matrix and D is the consumer demand matrix. The calculation AX = X ¡ D is the internal use of the model. The production matrix can be solved by the formula: X = (I ¡A)¡1D: °
