Concerns about energy security, reduced dependence on exhaustible fossil fuels and climate change have led to significant policy support for biofuels, particularly for cellulosic biofuels. The Biomass Crop Assistance Program and volumetric tax credits for biofuels seek to supplement the...

This paper develops a conceptual framework and a numerical simulation model of the fuel and agricultural sectors in the US to analyze the effects of the existing Renewable Fuels Standard (RFS) that mandates the blending of specific volumes of low carbon biofuels with liquid fossil fuels and a...

This paper examines the changes in land use in the U.S. likely to be induced by biofuel and climate policies and the implications of these policies for GHG emissions over the 2007-2022 period. The policies considered here include a modified Renewable Fuel Standard (RFS) by itself as well as...

Using a unique county-level panel on crop yields and daily weather dataset over the past decade, we estimate the impact of climate change on corn and soybean yields in China. Our results suggest the existence of nonlinear and asymmetric relationships between corn and soybean yields and climate...
