How Much are American Drivers Willing to Pay for Ethanol?

New AAEA member research on E85 versus E10 gasolines

The Renewable Fuel Stanard (RFS) is a program, set by federal law in 2005, which mandates that motor fuels sold in the United States contain minimum amounts of renewable fuels. The objectives of the program are to reduce greenhouse gas emissions, support the farm sector, and reduce the United States dependence on oil imports. Increasing amounts of renewable fuels have been blended into transportation fuel every year.

According to the Environmental Protection Agency, E85 fuel is a blend of gasoline and denatured ethanol containing up to 85% ethanol, making it the highest ethanol fuel blend available in the market. E10, on the other hand, is a low-level blend composed of no more than 10% ethanol. With these two fuel blends at opposite ends of the spectrum, how much are motorists really willing to pay for E85 compared to E10?

This is the question that Sebastien Pouliot from Iowa State University, Kenneth Liao from Farmingdale State College, and Bruce Babcock from the University of California, Riverside, wanted to answer in their research “Estimating Willingness to Pay for E85 in the United States Using an Intercept Survey of Flex Motorists."

Their research published in the American Journal of Agricultural Economics is available now and opened to the public for a limited time. If you are interested in setting up an interview with Sebastien Pouliot, please contact Allison Scheetz in the AAEA Business Office.
