Outlook for Grain and Oilseed Export Shipments from the Upper Mississippi River Basin
应参议员要求，FAPRI评估了上密西西比河船闸系统升级问题，对比了美国陆军工程兵团与FAPRI、IFPRI的出口预测，为政策制定者提供决策参考。
In response to a request by Senator Tom Harkin, the Food and Agricultural Policy Research Institute (FAPRI) has evaluated a number of issues related to the lock and dam system on the Upper Mississippi and Illinois Rivers. One critical issue is how future demand for agricultural exports will affect the demand for river transportation services. This paper sketches a theoretical framework for economic decision-making regarding the upgrade of the lock and dam system of the Upper Mississippi River and then compares export projections underlying analyses by the U.S. Army Corps of Engineers (USACE) with recent projections by FAPRI and the International Food Policy Research Institute (IFPRI).
