The impact of quotas on the optimal adjustment of milk production at the farm level
构建了一个经济模型，研究面临牛奶交付配额的单个农场如何最优调整生产，发现短期和中期应同时减少饲料投入和奶牛数量，长期则仅减少奶牛数量。
An economic model is developed for the optimal adjustment of milk production on an individual farm faced with a delivery quota. The model is based on the general neoclassical theory of production, taking into account the complicated relations between the production of milk and beef. The application of the model is illustrated by some examples with varying assumptions. The results show that in the short- and medium-term the adjustment should take place by a simultaneous reduction in the feed input and in the number of cows in the herd. As expected, the long-run adjustment should take place only by a reduction in the number of cows.
