Looking for nonnegative solutions of a Leontief dynamic model.
In Section 2, the authors briefly review some useful terminology and results. In Section 3, using properties about nonnegative matrices they obtain sufficient conditions in order that the Leontief price model have nonnegative solutions, and then give many illustrative numerical examples. Finally, in Section 4, taking into account these results they draw some conclusions on the problem of nonnegativity of the solutions of the model.
