Estimating a complete matrix of demand elasticities for feed components using pseudo data: A case study of Dutch compound livestock feeds
通过线性规划模型模拟配合饲料制造商的成本最小化行为，并拟合平滑成本函数，估计了荷兰饲料原料需求的完整自价格和交叉价格弹性矩阵。
A complete set of direct- and cross-price elasticities of demand for livestock feed ingredients in the Netherlands is estimated using a relatively new approach. Cost minimizing behaviour of compound feed manufacturers is modelled in a linear programming formulation. That formulation is then approximated by fitting a smooth cost function to optimal solutions over a sample of different feed ingredient prices. Elasticities are then evaluated along the smooth curve.
