Problem Statement

• Limited research available on the market for ethanol.

• To determine the effectiveness of current subsidies for ethanol, the economic structure of the fuel-blending market for ethanol is required.

Objectives• Investigate the impact market determinants

have on the ethanol market.

• Develop an econometric model of the fuel-blending market demand and supply for ethanol.

• Based on this econometric model, elasticities are calculated and implications for this highly subsidized market are discussed.

Alternative Fuel Legislation

• Alternative Motor Fuels Act (AMFA) of 1988

• Clean Air Act Amendments (CAAA) of 1990

• Energy Policy Act (EPACT) of 1992• Federal Ethanol Subsidy of $0.54 per

gallon• Additional State Subsidies

Ethanol• Ethanol is an alcohol-based, colorless liquid

fuel with a characteristic odor.• Currently, ethanol is used as a fuel additive

in gasoline.• In the U.S., corn is the predominant

feedstock in ethanol production.• Ethanol is produced through a process of

fermenting and distilling starch crops that have been converted into simple sugars.

Competition

Methyl Tertiary-Butyl Ether (MTBE)

• First synthesized in the early 1960s and commercial production began in 1979.

• Classified as a volatile organic compound (VOC).

• Produced by a chemical reaction between methanol and isobutylene.

Q = annual ethanol quantity soldPw = lagged price wedge (Peth – Pmtbe)Pg = annual grade-weighted wholesale price of gasolineV = annual number of registered vehicles by stateCAAA = Clean Air Act non-attainment dummy variableR = regional dummy variable

Data

• Data were collected from the Economic Research Service, the U.S. Department of Transportation, the Energy Information Administration, and the U.S. Environmental Protection Agency.

• The data set includes: 1988 to 2002 annual observations by state.

Market Implications• With fuel-marketing firms bearing the major

impact of any ethanol subsidy removal (91%), any reduction in the subsidy will negatively impact ethanol’s competitiveness over MTBE.

• A gradual phase-down of the subsidy will be dramatic for the industry.

• A 45% reduction in the ethanol subsidy will result in the elimination of the ethanol market.

Impacts

• If a state is designated in non-attainment, ethanol demand will increase by 14 million gallons.

• An elastic input demand for corn limits any bargaining leverage corn producers have in their attempts to influence market price.

• The increases in state ethanol subsidies over the last decade have not resulted in inducing a positive ethanol supply response.

Conclusions• The economic structure of the ethanol

market indicates ethanol agents are addicted to the federal tax exemption on ethanol blended fuels.

• The potential for demand expansion resides in structural shifts occurring from clean air and water regulations, health restrictions, renewable fuels, and global warming.
