Tiene como notas diferenciales respecto a la anterior edición: la reestructuración del esquema organizativo general para acercarlo a la cosmovisión de la disciplina que generalmente tienen los economistas y hacerlo compatible con otros esquemas académicos; la reducción y sustitución de descriptores y la introducción de nuevos conceptos o la nueva formulación de otros ya existentes.
