英文文献摘要：
Farm milk prices in the United States fluctuated throughout the 2000-2009 decade. Dairy farmers, industry pundits, and policymakers all reacted with much alarm. One point of concern has been the response of retail prices to farm price volatility. This study investigates farm-to-retail price transmission for two major dairy products – whole milk and Cheddar cheese – in the 2000s. Results show that price shocks at the farm gate were transmitted asymmetrically to retail. However, in order to best identify the nature of the transmission process, it is important to fit alternative model specifications.

从2000年到2009年，美国的牛奶价格一直在波动。奶农、行业专家和政策制定者都对此大为震惊。令人担忧的一点是零售价格对农产品价格波动的反应。这项研究调查了21世纪初，全脂牛奶和切达奶酪这两种主要乳制品从农场到零售市场的价格传导。结果表明，农场大门处的价格冲击不对称地传递给零售业。然而，为了最好地确定传输过程的性质，适应替代模型规范是很重要的。
