Available estimates of the land use changes and greenhouse gas emissions of biofuels differ significantly across economic models. This paper focuses on the impacts of price-induced yield assumptions on U.S. corn ethanol results. These assumptions have dramatic impacts within the FAPRI modeling framework, but limited ones within the GTAP-BIO model. I show that these sensitivity to yield assumption results are not comparable because the ex ante land and production elasticities assumed in these two models are not comparable. The analysis reveals that the current focus solely on the value of the price-induced yield elasticity can be misleading.

    Using bio-fuels, such as bio-ethanol or bio-diesel in transportation, or biomass in power generation reduces CO2 emissions as the carbon is fixed by the plants from the atmosphere and saves the equivalent fossil fuel. The perennial rhizomatous C4 grass Miscanthus has one of the highest energy...
