Characteristics of Grain Elevators that Contract with Railroads
使用逻辑模型分析1983-85年间美国谷物升降机与铁路签订合同的特征，发现发货量、服务铁路数量和公司隶属关系显著影响合同获得概率。
Abstract The Staggers Rail Act of 1980 allowed contracts between railroads and shippers which have resulted in increased grain prices to some farmers while, at the same time, increasing competitive pressure on some local grain elevators. This study employs a logistic model designed for complex survey designs to identify characteristics of elevators that had railroad contracts during 1983–85. The total volume shipped from an elevator, number of railroads serving an elevator location, and affiliation with elevator firms serviced by more than one railroad company are found to contribute significantly to the probability of a grain elevator receiving a railroad contract.
