| This paper describes a global model for agriculture and bioenergy (GLOMAB) that incorporates biomass, biofuels and bioelectricity sectors into the GTAP-Energy model by expanding the global GTAP database, production and consumption structures. Biofuels are separated between first- generation (sugar ethanol, starch ethanol) and second- generation (cellulosic ethanol) biofuels and associated biomass feedstocks (maize, sugar cane, crop residues, woody biomass). Beside biofuels, the model also incorporates bioelectricity (as separate form conventional electricity) which competes for the same biomass feedstocks with cellulosic ethanol sector (agricultural residues, woody biomass). With this broad-based representation of the bioenergy system likely to prevail... |

| As the hunt for renewable energy sources from agriculture intensifies, many agricultural producers are contemplating what crops to grow in the foreseeable future. On the one hand, there are traditional food crops, such as soybean, corn, and wheat, which have recently enjoyed a spike in prices, primarily because of the seemingly ever-growing demands of the corn to ethanol industry. On the other hand, there are the lesser-known perennial energy crops, such as switchgrass. Although much information on various aspects of switchgrass production exists, this paper discusses the adaptation of existing production and processing information to Arkansas conditions as a potential alternative to crop production. |

| In light of the large volumes of pine killed in the Interior forests in British Columbia by the mountain pine beetle, many are keen to employ forest biomass as an energy source. To assess the feasibility of a wood biomass-fired power plant in the BC Interior it is necessary to know both how much physical biomass might be available over the life of a plant, but also its location because transportation costs are likely to be a major operating cost for any facility. To address these issues, we construct a mathematical programming model of fiber flows in the Quesnel Timber Supply Area of BC over a 25-year time horizon. The focus of the model is on minimizing the cost of supplying feedstock throughout space and time. Results indicate that over the life of the... |

| Activities that remove CO2 from the atmosphere and store it in forest and agricultural ecosystems can generate CO2-offset credits that can thus substitute for CO2 emissions reduction. Are biological CO2-uptake activities competitive with CO2 offsets from reduced fossil fuel use? In this paper, it is argued that transaction costs impose a formidable obstacle to direct substitution of carbon uptake offsets for emissions reduction in trading schemes, and that separate caps should be set for emissions reduction and sink-related activities. While a tax/subsidy scheme is preferred to emissions trading for incorporating biologically-generated CO2 offsets, contracts that focus on the activity and not the amount of carbon sequestered are most likely to lead to the... |

| A carbon tax would penalize carbon intensive fuels like gasoline and shift fuel consumption to less carbon intensive alternatives like biofuels. Since biofuel production competes for land with agriculture, a carbon tax could raise land rents, divert land towards fuel production, and raise agricultural prices. This paper analyzes the welfare effect of a carbon tax on fuel with gasoline and biofuel as available fuel choices, in the presence of a labor tax and biofuel subsidy. The second-best optimal carbon tax is also quantified. Findings show that when biofuels is part of the fuel mix, the carbon tax has a commodity price effect which arises from tax-induced changes in land rent. The commodity price effect could exacerbate or attenuate the tax interaction... |

| Increased use of alternative fuels and low commodity prices have contributed to the recent expansion of the U.S. ethanol industry. As with any competitive industry, some level of output price risk exists in the form of volatility; yet, no actively traded ethanol futures market exists to mitigate output price risk. This study reports estimated minimum variance cross-hedge ratios between Detroit spot cash ethanol and the New York Mercantile Exchange unleaded gasoline futures for 1-, 4-, 8-, 12-, 16-, 20-, 24-, and 28-week hedge horizons. The research suggests that a one-to-one cross-hedge ratio is not appropriate for some horizons. |
