An Economic Evaluation of a Multimodal Transportation System: Grain Transportation in Eastern Washington


Multimodal systems offer efficiencies from complementary and competitive interactions. This study uses a least cost spatial equilibrium model to determine how alternative policies and firm decisions affect the performance of a multimodal grain transportation system. The analysis finds this system is extremely competitive and much of the competitive structure comes from intermodal movement via truck-barge. It also found that the operating structure of the shipping firm utilizing the system directly affects the performance.
