The Measurement of Grain Barge Demand on Inland Waterways: A Study of the Mississippi River

Although the knowledge of grain barge demand is important to the barge industry, farmers and the authorities that manage the river lock system, few studies have addressed the demand of grain barge transportation on the Mississippi River. This paper estimates structural demand for grain barge transportation on the upper Mississippi River in order to improve understanding of forces impacting demand. Results suggest that there is an inelastic demand for grain barge transportation on the upper Mississippi in the short run while the price elasticity increases to 1.0 in the longer run. Foreign grain demand and domestic grain consumption also are found to influence grain barge demand. The winter season and floods affect demand negatively. Hausman's specification test shows the ordinary least square and two-stage least square estimates are statistically invariant. Competing and complementary transportation modes may affect upper Mississippi River grain barge demand, but the results for most modes are not found to be statistically significant in this study.
