This paper analyzes the effect that the imminent reform of the EU sugar beet regime will have on United Kingdom (UK) sugar beet farms. Specifically, we estimate a multi-product cost function to analyze the effect the changes on the sugar beet price support and quota will have on the crop allocation of sugar beet farms and their aggregate use of inputs. Based on these estimates we discuss the implications that changes in the crop patterns may have on farm environmental variables such as soil loss and groundwater pollution.
