Response of Irish creamery milk supply to price changes
研究了爱尔兰奶油厂牛奶供应对牛奶相对价格变化的反应，发现加入欧共体后价格反应更大，且技术效应虽为正但不显著。
Precis: This article investigates the responsiveness of creamery milk supply to changes in the price of milk relative to agricultural materials. A basic model, which includes milk and livestock price variables and a Gini co-efficient of cow concentration (a proxy for technological change) is modified to test pre- and post-EEC response differences. The effects of the milk price variables are isolated using the method of principal components. Price responsiveness was higher in the post- than pre-EEC period with largest responses shown after a two to three year lag. The technology effect although positive was not significant.
