Existence and uniqueness of solutions for Leontief's Input–Output Model, graph theory and sensitivity analysis
We provide a complete study of existence and uniqueness (uniqueness up to multiples in the case d=0) of non-negative and non-trivial solutions x for the linear system (I−A)x=d with A≥0,d≥0 (which, ...
