Abstract In this paper we consider not necessarily symmetric co-positive as well as semi-monotoneQ-matrices and give a set of sufficient conditions for such matrices to beR 0-matrices. We give several examples to show the sharpness of our results. Construction of these examples is based on the following elementary proposition: IfA is a square matrix of ordern whose first two rows are identical and bothA 11 andA 22 areQ-matrices whereA ii stands for the principal submatrix ofA obtained by deleting rowi and columni fromA, thenA is aQ-matrix.
