Note and comment. On Sraffa's price system
利用希克斯的存量与流量均衡区分，重新解读斯拉法的《用商品生产商品》，将其价格体系描述为独立于流量均衡的存量均衡，有助于理解斯拉法著作中的难点并看清古典与新古典方法的根本差异。
This paper offers a novel interpretation of Sraffa's Production of Commodities (1960) by making use of the distinction between stock and flow equilibria drawn by Hicks in Capital and Growth (1965). Sraffa's price system is described as an economy-wide stock equilibrium - defined and analysed independently of the conditions of flow (supply and demand) equilibrium. The merits of this interpretation are twofold: first, it allows certain elements of Sraffa's book which have perplexed some readers to be more readily understood; and, second, it allows one to see more clearly the fundamental differences in method of the modern classical and neoclassical approaches to economics.
