The Russian invasion of Ukraine disrupted grain flows from that region. As a result of the invasion, Ukraine has evolved from a country with some of the lowest logistical costs in the world to having the highest logistical cost. This paperÕs purpose is to analyze the effects of the Russian invasion on the logistical functions and the costs for corn exports from Ukraine and its competitors using an optimized Monte Carlo simulation model. Most important are the effects of the radical increase in shipping costs from Ukraine, reduced port capacity and export supplies.

Forward pricing and allocation mechanisms for rail transportation serve critical functions for the grain-marketing system. We examine the effects of shipping costs on the origin and export basis using a panel simultaneous-equations model. Results indicate that the origin and export basis are determined simultaneously, with each one affected by the dynamic variability of shipping costs. On average, a $1 increase for the shipping costs decreases the origin basis by $0.19 and increases the export basis by $0.82/bu of soybeans. The interaction between shipping cost and exports on the export basis impacts both marketing and trading strategies in the grain-marketing system.

We estimate the expenditure, price, and Engel parameters for the major U.S. caloric sweeteners (sugar, high-fructose corn syrup [HFCS], and glucose), for the 1975–2013 period using the quadratic almost ideal demand system (QUAIDS). The estimated parameters are then used to compute expenditure elasticities and both uncompensated and compensated price elasticities. We find that consumer expenditures are positively elastic for both sugar and HFCS but not for glucose. The own-price elasticity of demand for sugar is less elastic compared to those of HFCS and glucose. Our results will help design an effective U.S. sweetener tax policy.
