R enewable energy—especially biofuels—is a very hot topic in the United States and in many other countries around the world. Although governments have been promoting biofuels for a long time, the real boom began in 2005 and continues to the present. In this article I explore the history of biofuels, describe the current situation, examine alternative(More)
The biofuel industry has been rapidly growing around the world in recent years. Several papers have used general equilibrium models and addressed the economy-wide and environmental consequences of producing biofuels at a large scale. They mainly argue that since biofuels are mostly produced from agricultural sources, their effects are largely felt in(More)
I n the past, agricultural markets have been well integrated. Markets for different energy commodities, especially liquid energy products, also have been tightly linked. But agricultural markets and energy markets have not been closely correlated. Table 1 contains partial correlation coefficients between pairwise prices (both levels and first differences)(More)
With cellulosic energy production from biomass becoming popular in renewable energy research, agricultural producers may be called upon to plant and collect corn stover or harvest switchgrass to supply feedstocks to nearby facilities. Determining the production and transportation cost to the producer of corn stover or switchgrass and the amount available(More)
We evaluated several variants of a variable biofuel subsidy and compared them with the fixed subsidy and Renewable Fuel Standard. We used two different modeling approaches. First we used a partial equilibrium model encompassing crude oil, gasoline, ethanol, corn, and ethanol by-products. Second, we used a stochastic simulation model of a prototypical(More)
Keywords: bioenergy biofuel climate change computable general equilibrium forestry greenhouse gas (GHG) a b s t r a c t Renewable energy is an option for many countries simultaneously seeking to reduce dependence on imported petroleum and to reduce greenhouse gas (GHG) emissions that contribute to climate change. Forestry can play a role in environmental(More)
This study evaluates the economic feasibility and stochastic dominance rank of eight cellulosic biofuel production pathways (including gasification, pyrolysis, liquefaction, and fermentation) under technological and economic uncertainty. A techno-economic assessment based financial analysis is employed to derive net present values and breakeven prices for(More)
We develop a theoretical model to identify conditions under which price and income changes are most likely to change weight. Although it is intuitive that raising the price of high-calorie food will decrease consumption of such goods; it is not clear that such an outcome will actually reduce weight. Our empirical analysis demonstrates a case where a tax on(More)
