The influence of the large scale mechanization of ware potato growing upon supply responsiveness in The Netherlands (1955–1978)
研究了荷兰商品马铃薯种植的大规模机械化如何影响供给反应，发现机械化显著降低了供给弹性，且产品价格比毛利润更适合作为解释变量。
This article brings together the findings of an investigation into the influence of large scale mechanization on the supply response of ware potatoes in The Netherlands (1955–1978). For this purpose the considered period has been divided into two sub-periods: the period before the introduction of the mechanization (1955–1965) and the period within which this mechanization started (1965–1978). A theoretical supply response model has been developed. The estimation results of this model with respect to the two sub-periods indicate that mechanization sharply reduced the supply responsiveness. The results did not support the hypothesis that the gross margin should be preferred to the product price as an explanatory variable.
