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...

A general theory is developed to analyze the efficiency and income distribution effects of a biofuel consumer tax exemption and the interaction effects with a price contingent farm subsidy. Using U.S. policy as an example, ethanol prices rise above the gasoline price by the amount of the tax...
