Maurice Potron is an important precursor of the study of linear models of production and, in particular, of input-output analysis. We show that, contrary to Abraham-Frois and Lendjel's interpretation which we consider as unfaithful to Potron's model, there is a clear connection between his...

An input-output (IO) system which is capable of producing any semi-positive net product by an adequate choice of the activity levels of its processes satisfies the 'adjustment' property. We analyze under which conditions the adjustment property holds for IO systems in which some produced goods...
