In the wake of high gasoline prices, the ethanol industry is making the rounds in Washington, and they want you to believe that the Renewable Fuel Standard has lowered gasoline prices by up to $.89 per gallon. This would be remarkable, if it were true. The ethanol industry relies on a study produced by the Center for Agricultural and Rural Development at the University of Iowa. Here is the abstract:
This report updates the findings in Du and Hayes 2009 by extending the data to December 2010 and concludes that over the sample period from January 2000 to December 2010, the growth in ethanol production reduced wholesale gasoline prices by $0.25 per gallon on average. The Midwest region experienced the biggest impact, with a $0.39/gallon reduction, while the East Coast had the smallest impact at $0.16/gallon. Based on the data of 2010 only, the marginal impacts on gasoline prices are found to be substantially higher given the much higher ethanol production and crude oil prices. The average effect increases to $0.89/gallon and the regional impact ranges from $0.58/gallon in the East Coast to $1.37/gallon in the Midwest. In addition, we report on a related analysis that asks what would happen to US gasoline prices if ethanol production came to an immediate halt. Under a very wide range of parameters, the estimated gasoline price increase would be of historic proportions, ranging from 41% to 92%.
