英文文献：Co-operatives in Oligopolistic Industries: The Western Canadian Fertilizer Industry
英文文献作者：Fulton, Murray
英文文献摘要：
This paper examines the impact of co-operatives on oligopolistic industries. The theoretical analysis suggests that the existence of a co-operative in the fertilizer industry can improve efficiency. In reality, however, the existing co-operative appears to behave more like a profit maximizing firm, resulting in continued market imperfections.
