A comparison of production technology using primal and dual approaches: The case of Dutch dairy farms
利用利润函数与生产函数之间的对偶性，开发了两个利润最大化农场模型，并采用荷兰奶牛场面板数据估计，发现两种模型计算的生产弹性和替代弹性无显著差异。
Two models of profit-maximising farms are developed using the duality that exists between the normalised profit function and the production function. Some production factors are fixed in the short term. The specification used is the translog form with variable intercepts. The equations are estimated with an incomplete panel using a SUR and 3SLS estimation method. The theoretical framework fits the data well. Assumptions often made about the production technology are tested. Linear homogeneity and Hicks' neutrality are rejected by both models. The production and substitution elasticities calculated by both models do not differ significantly. Therefore, using data from dairy farms in the Netherlands the dual models perform similarly.
