We analyze the long-term impacts of large-scale expansion of biofuels on land-usechange, food supply and prices, and the overall economy in various countries or regions using amulti-country, multi-sector global computable general equilibrium model augmented with an explicitland-use module and...

We employ an open economy general equilibrium model to investigate the effects of governmentenergy policy, with an emphasis on corn-based ethanol, on the U.S. economy. The modelspecification incorporates world and domestic markets, assumes pollution costs from fuelconsumption, and allows...

Significant government support for biofuels has led to rapid growth in U.S. ethanol production andresearch to develop more advanced biofuels. In this paper we construct a general equilibrium, openeconomy model that captures the rationale typically invoked to justify government intervention in...

We quantify the emergence of biofuel markets and its impact on U.S. and world agriculturefor the coming decade using the multi-market, multi-commodity international FAPRI (Food andAgricultural Policy Research Institute) model. The model incorporates the trade-offs betweenbiofuel, feed, and food...
