Some Remarks on Vertically Integrated Sectors

JOINT PRODUCTION ANALYSIS IN A SRAFFIAN FRAMEWORK1

“…And Potestio ( 1980) has noted the analogous point about matrix [( B -A )-I B].I4 It may be added here that the same qualitative property holds good for matrix [( B -1A )-'A], where the real number 1 is nonnegative and less than the maximum growth factor. All these results of Steedman (1977b), Pasinetti (198Oa), Potestio (1980), and that just given are implicit in the work of Manara (1968) on the distinction between basics and non-basics in square joint production systems. Manara's mathematical argument will not be reported here but the interested reader will wish to consult Section 6 of his paper.…”
