推导了同质雌性畜群库存管理的市场均衡动态,发现短期供给对永久需求变化呈向后弯曲,对暂时需求变化则上升,解释了生猪和肉牛库存周期。
Abstract Market equilibrium dynamics of herd inventory management are derived for homogenous female populations. Short‐run supply is backward bending in response to permanent changes in demand and is rising in response to transitory changes in demand. Increasing inventories are associated with high and falling prices and decreasing inventories with low and rising prices, but there is no market instability in this. These unusual intertemporal substitution effects follow from both rational expectations and appropriately formulated cobweb models and go part of the way toward explaining hog and cattle inventory cycles.
