摘要: The overall value of the Ghosh model is appraised. Its treatment quantities and prices scrutinized by examining variant with data in prices, price indexes. methodology involves returning to accounting equations shows that: (i) offers solutions limited interest, being incapable providing or indexes separately from quantities; (ii) what taken be equation Ghosh's actually that physical model; (iii) may serve for cost-push exercises, but dual Leontief performs same task a much simpler more natural way; (iv) Cronin's mixed models do not mix hypotheses.
