The impact of quotas on the optimal adjustment of milk production at the farm level: a comment
评论Rasmussen和Nielsen（1985）关于配额导致牛奶产量减少的结论，指出除非牛舍容量受限，否则减少每头牛饲料只是次要调整，主要源于奶牛投入的不可分性，并考察了农场决策与行业短期均衡的联系。
In a recent article Rasmussen and Nielsen (1985) conclude that a quota-induced reduction in milk production occurs through a decrease in feed per cow and only if this is insufficient is there a reduction in the number of cows. Here it is shown that, in their model, unless the capacity of the stalls is a binding constraint, any reduction in feed per cow is of second-order importance and solely the result of the indivisibility of the cow input. Moreover, the connections between farm-level decisions and the short-run, industry equilibria implied by their model are examined.
