Welfare Comparisons of U.S. Dairy Policies with and without Mandatory Supply Control
用动态计量模型模拟强制供给控制对均衡价格、数量、生产者与消费者福利及政府成本的影响，发现该政策虽消除价格支持成本，但生产者获益以消费者和加工商受损为代价。
Abstract The existence of costly dairy surpluses has led some policy makers to argue in favor of mandatory supply controls as an alternative to existing dairy policy. A dynamic econometric model is used to simulate the changes in equilibrium prices, quantities, producer and consumer welfare, and government costs that would occur if mandatory controls were adopted. The results show that while such a change in policy would eliminate the costs associated with current price supports, the benefits accruing to producers would be achieved at the expense of consumers and processors.
