On the consistency of commodity-based technology in the Make-Use model : a new interpretation.

Most national accounting systems are based on the Make-Use model. Two hypotheses are traditionally made featuring either industry-based (IBT) or commodity-based (CBT) technologies. IBT corresponds to a consistent demand-driven model: its solution can be explained as a circuit or in probabilistic terms, even in the rectangular case. CBT obliges to compute an inverse matrix which is impossible when rectangular, fails to indicate how a commodity is distributed throughout industries and precludes interpretation of CBT as a circuit or in probabilistic terms. CBT should be interpreted as supply-driven to recover its coherence as a circuit even in the rectangular case.
