Modeling the Environmental and Socio-Economic Impacts of Biofuels

This paper provides a general overview of the social, environmental, and economical issues related to biofuels and a review of economic modeling of biofuels. The increasing importance of biofuels is driven primarily by government policies since currently available biofuels are generally not economically viable in the absence of fiscal incentives or high oil prices. Also the environmental impacts of biofuels as an alternative to fossil fuels are quite ambiguous. The literature review of the most recent economic models dealing with biofuels and their economic impacts provides a distinction between structural and reduced form models. The discussion of structural models centers primarily on computable general equilibrium models. The review of reduced models is structured toward the time series analysis approach to the dependencies between prices of biofuels, prices of agricultural commodities used for the biofuel production and prices of the fossil fuels. -- Biofuels ; Ethanol ; Biodiesel ; Prices ; Time-series
