The Determination of Optimum Buffer Stock Intervention Rules
在线性供需曲线且存在随机平移因素的情况下，结合缓冲库存成本，推导出使贸易伙伴联合预期净收益最大化的最优价格干预区间，该区间随供需弹性等市场条件变化。
It has been established for some time in the case of linear supply and demand curves that are subject to parallel stochastic shift factors that the joint welfare of trading partners measured as the sum of consumers' and producers' surpluses is increased by a reduction of price instability. This paper seeks to combine this result with information on the costs of buffer stock schemes to establish the optimum degree of price stabilization. The maximization of the partners' joint expected net benefit yields an optimum intervention price range that will vary with demand and supply elasticities, and other market conditions.
