Abstract

En este artículo presento algunos comentarios sobre la forma triangular del modelo de Leontief. Entre ellos, propongo una demostración alternativa de la equivalencia entre la existencia de una solución viable para el modelo y la condición de Hawkins y Simon (H-S). Además, expongo el peculiar significado económico de los coeficientes de la diagonal principal en la forma triangular de la matriz de Leontief, lo cual permite, entre otras cosas, apreciar la estrecha relación entre las condiciones económicas y las matemáticas en la solución del modelo. También identifico algunas proposiciones matemáticas equivalentes a (H-S) que poseen interés económico.
