Adoption Subsidies and the Environmental Impacts of Alternative Energy Crops, Center for Agricultural and Rural Development (CARD) Briefing Paper 07-BP 50, Iowa State University, March 2007 - The authors estimate the costs associated with converting land from production of traditional crops to switchgrass. The results indicate that farmers will convert to switchgrass production only with significant conversion subsidies.
The Long-Run Impact of Corn-Based Ethanol on the Grain, Oilseed, and Livestock Sectors: A preliminary assessment, Center for Agricultural and Rural Development (CARD) Briefing Paper 06-BP 49, Iowa State University, November 2006 - The ongoing growth of corn-based ethanol production raises some fundamental questions about what impact continued growth will have on U.S. and world agriculture. The authors estimate the long-run potential for ethanol production by calculating the corn price at which the incentive to expand ethanol production disappears.
Removal of U.S. Ethanol Domestic and Trade Distortions: Impact on U.S. and Brazilian ethanol markets, Center for Agricultural and Rural Development (CARD) Working Paper 06-WP 427, Iowa State University, October 2006 (revised) - Using a multi-market international ethanol model calibrated on 2005 market data and policies, the authors analyze the impact of trade liberalization and removal of the U.S. federal tax credit on U.S. and Brazilian ethanol markets. The removal of trade distortions and $0.51 per gallon tax credit to ethanol refiners induces a 16.5 percent increase in the world ethanol price.
