The analysis is based on an integrated climatic, agronomic and economic model of grain production in the midwestern region of the U.S. The model represents a typical farm and the objective is to select an optimum combination of cultivars for four crops (maize, soybean, wheat and sorghum)...

With a mandate, U.S. policy of ethanol tax credits designed to reduce oil consumption does the exact opposite. A tax credit is a direct gasoline consumption subsidy with no effect on the ethanol price and therefore does not help either corn or ethanol producers. To understand this, consider...

This paper proposes a trade restrictiveness indicator that explicitly incorporates environmental externalities. The index employs directional distance functions and use indicators (i.e. differences rather than ratios) modified to account for and evaluate efficiency changes in the face of...

We show how leakage differs, depending on the biofuel policy and market conditions. Carbon leakage is shown to have two components: a market leakage effect and an emissions savings effect. We also distinguish domestic and international leakage. International leakage is always positive, but...
