A basis model is used to empirically estimate the impact of ethanol production on the South Dakota com basis on the district and "State" levels. Monthly data is used to estimate basis as a function of futures price, supply, demand, storage, and transportation costs. The independent variables used are com futures prices, com production, com usage for ethanol production, com usage by cattle, Midwest No. 2 Diesel retail sales prices, storage availability, and unit train transportation The regression results show the impact on com basis varies by district from $0.04 to $0.27 per bushel, with a "State" impact of $0.24 in 2005. The impact from an additional 40 million gallon per year (MGY) ethanol plant ranges from $0.06 to $0.16 per bushel, with a "State" impact of$0.03. The impact from an additional 100 MGY ethanol plant ranges from $0.16 to $0.40 per bushel, with a "State" impact of $0.08.
