Acreage Response Under Canada's Western Grains Stabilization Program
估计了加拿大草原地区的总种植面积供给模型，假设农民基于每公顷收益的预期和方差做短期决策，并纳入西部谷物稳定计划的结构模型，发现该计划在1976-1990年间使种植面积小幅增加。
Abstract An aggregate acreage supply model for the Canadian prairies is estimated assuming that farmers base short‐run acreage decisions on the ex ante rational expectation and variance of per‐hectare revenue. To account for the effects of government intervention, a structural model of the Western Grains Stabilization Program is incorporated into the estimation framework. Results indicate the Program contributed to modest increases in cropped acreage between 1976 and 1990.
