Specification of trade in intermediate by-products in aggregate models of supply: A case study
研究了在总线性规划模型中，中间副产品价格外生设定如何导致最终产品供给估计偏差，并以西德奶牛场模型为例，比较了三种犊牛贸易设定对牛奶供给估计的影响。
The exogenous determination of prices of intermediate by-products in aggregate linear programming models results in biased supply estimates of the final products. In this article the effects on estimated levels and marginal changes in milk supply of three alternative specifications of trade in calves are investigated using a representative farm model of West German dairy production.
