英文文献摘要：
This paper assesses the impact of the milk income loss contract program on U.S. dairy producers. The Milk Income Loss Contact (MILC) program was created through the 2002 farm bill, which financially compensates dairy producers when domestic milk prices fall below a predetermined Boston Class I trigger price. MILC payments were made to eligible dairy producers/farms on a per cwt basis at a rate equal to 45 percent of the difference between the trigger price of $16.94 and the Boston Class I milk price. In the analysis, the 20 major milk-producing states were analyzed to determine if MILC payments caused a milk supply response to be different across these states. By dividing the U.S. into states, this will give a better understanding of production decisions based on the availability of inputs. To test the hypothesis, milk production was regressed against each state's All Milk price, MILC payments, production trends, the milk-feed price ratio, and average productivity per dairy farm in each state. Data were collected over an 10-year period (1995-2004), and MILC variable was used as a dummy variable in the model. The a priori expectations suggest that, in certain states, MILC payments will dampen the state's milk supply response to low milk prices. However, results may also help explain why a state increased or decreased milk production after the implementation of the MILC program. Of the 20-states, those dairies located in the west and southwest regions of the U.S. experienced the largest increases of production during the selected eight years. OLS regression results obtained from the individual state models report mixed results and generally failed to support the hypothesis that MILC did alter the response of monthly milk production to All Milk prices.
牛奶收入损失联系(MILC)项目是通过2002年的农场法案创建的，该法案规定，当国内牛奶价格低于预先确定的波士顿一级牛奶价格时，牛奶生产商将得到经济补偿。MILC支付给符合条件的乳品生产商/农场的费用是每cwt价格16.94美元的触发价格与波士顿一级牛奶价格之间的差额的45%。在分析中，对20个主要产奶州进行了分析，以确定MILC支付是否会导致这些州的牛奶供应反应不同。通过将美国划分为各州，这将更好地理解基于投入可用性的生产决策。为了验证这一假设，我们对每个州的所有牛奶价格、MILC支付、生产趋势、牛奶饲料价格比率和每个州每个奶牛场的平均生产率进行回归分析。数据收集时间跨度为10年(1995-2004年)，MILC变量作为模型中的虚拟变量。先验预期表明，在某些州，MILC的支付将抑制该州的牛奶供应对低牛奶价格的反应。然而，研究结果也可以帮助解释为什么一个州在实施MILC计划后牛奶产量增加或减少。在这20个州中，那些位于美国西部和西南部地区的奶牛场在选定的8年中经历了最大的产量增长。从单个状态模型得到的OLS回归结果报告了混合的结果，并且通常不能支持MILC确实改变了每月牛奶产量对所有牛奶价格的反应的假设。
