Effects of Improving Transportation Infrastructure on Competitiveness in World Grain Markets

Abstract South America has emerged as a major competitor of the United States in world grain markets. Spatial models of the international corn and soybean economies are used to evaluate the effect of recent and expected improvements in transportation infrastructure in South America on competitiveness in world grain markets. Results suggest these improvements yield noteworthy gains in South America with producer revenues increasing over

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

Argentina and Brazil have emerged as major U.S. competitors in world grain markets. The effect of recent and planned transportation infrastructure improvements on their international competitiveness is to be determined. Existing and planned transportation system improvements in South America that increase transportation and logistical efficiency on export-grain corridors are identified, and with the use of spatial models of the international corn and soybean economies, the effect of the enhanced transportation efficiency on international competitiveness is evaluated. Results show that the transportation system improvements yield noteworthy gains in South America, with producer revenues increasing by more than
