IS THE GHOSH MODEL INTERESTING?*
评估了Ghosh模型的价值，指出其在处理数量与价格时存在局限，无法分离价格与数量，且其价值模型方程实为实物模型方程，成本推动任务可由Leontief模型对偶更简单自然地完成。
ABSTRACT The overall value of the Ghosh model is appraised. Its treatment of quantities and prices is scrutinized by examining the variant with data in quantities and prices, and the variant with data in value and price indexes. The methodology involves returning to the accounting equations and shows that: (i) the Ghosh model offers solutions of limited interest, being incapable of providing prices or price indexes separately from quantities; (ii) what is taken to be the equation of Ghosh's value model is actually that of Ghosh's physical model; (iii) the Ghosh model may serve for cost‐push exercises, but the dual of the Leontief model performs the same task in a much simpler and more natural way; and (iv) Cronin's mixed models do not actually mix Leontief and Ghosh hypotheses.
