We estimate the impact of the 2012 removal of the Canadian Wheat Board's (CWB) single‐desk on the spatial pattern of durum wheat acres in Western Canada. We analyze changes in durum seeded acres with a panel regression and Census Agricultural Region data from 2004 to 2016. Our results indicate that removal of the CWB single‐desk had a significant impact on total durum production in Western Canada. In addition, we find that the spatial distribution of durum wheat acres shifted away from marginal durum‐growing areas and toward drier areas, an increase in specialization that arguably improved the efficiency of resource allocation.

国家贸易放松管制和硬粒小麦生产

我们估算了2012年撤除加拿大小麦委员会（CWB）单一办公桌对加拿大西部硬质小麦种植面积的影响。我们使用面板回归和2004年至2016年人口普查农业区的数据分析了硬粒小麦播种面积的变化。我们的结果表明，拆除CWB单工位对加拿大西部硬粒小麦的总产量有重大影响。此外，我们发现硬质小麦种植面积的空间分布从硬质硬质小麦种植区转移到较干燥的地区，专业化程度的提高可以说提高了资源分配的效率。
