This paper shows that results obtained in the Sraffian literature on joint production are relevant for input—output economists working in the tradition of Leontief. We concentrate upon the 'adjustment' property, i.e. the ability of a system to cope with any variation in final demand. We...

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...
