TL;DR: In this article, a non-linear input-output system is constructed on the basis of neoclassical production technologies, and four results are reported: (i) there exists a unique solution to the developed input output system; (ii) every real square matrix can be the Jacobi matrix of the function relating gross outputs to net outputs; (iii) if the system has a solution at a final demand vector, there is a solution near it; and (iv) when the final demand for a commodity increases, its price never decreases.
