Abstract

This paper explores optimal biofuel subsidies in a general equilibrium trade model. The focus is on the production of biofuels such as corn-based ethanol, which diverts corn from use as food. In the small-country case, when a Pigouvian tax on conventional fuels is in place, the optimal biofuel subsidy is zero. When the tax on crude is not available as a policy option, however, a second-best biofuel subsidy may or may not be positive, depending on the input elasticity of substitution in energy production. In the large-country case, a biofuel subsidy spurs global demand for food and confers a terms-of-trade benefit to the food-exporting nation. In the absence of beggar-thy-neighbor trade policy tools, the twin objectives of pollution reduction and term-of-trade improvement justify a combination of crude tax and biofuel subsidy for the food exporter. If the food importer also uses a biofuel subsidy (or tax), we have a Johnson (1953) type Nash equilibrium augmented by pollution considerations. If biofuel subsidies reduce global crude use, then in a Nash equilibrium, the food-exporting nation must use a subsidy, while a food-importing nation will impose a subsidy if and only if the pollution-reduction effect dominates the terms-of-trade effect.
