| This study explores the interactions of groundwater extraction, quality, and greenhouse-gas (GHG) emissions within a productive agricultural region. Two conceptual models are proposed. In the first, GHG emissions are managed at the local level, and an efficient level of abatement is solved for endogenously to the system. Here, regional management of GHG emissions offers an alternative policy tool for managing quantity/quality by internalizing the costs of a common externality associated with both groundwater extraction and nitrogen fertilizer application. A simple numerical simulation is used to illustrate the potential groundwater co-benefits of managing agricultural GHG emissions within the system. The second model reflects the reality that GHG... |

| Because of public health concerns, regulators are considering requiring post-harvest treatment of halfshell and shucked oysters by wholesalers and processors. Two recently developed post-harvest treatment technologies may actually reduce the costs of producing shucked oysters, but would increase the costs of halfshell oysters. An interregional model of the wholesale oyster industry is developed to estimate the effects of treatment requirements on prices, output, and employment. If post-harvest treatment is required for all Gulf oysters, price increases are estimated to be less than 20% and, in some cases, prices decrease. Results indicate producer and consumer losses in the halfshell market are partially or more than offset by gains in the shucked market. |

| We use the Agricultural Sector Model to analyze the economic potential of soil carbon sequestration as one of several agricultural greenhouse gas emission mitigation strategies, including afforestation. For low incentives on carbon emission savings, agricultural soil carbon sequestration is the most cost-efficient strategy. As incentive levels increase above $50 per ton of carbon equivalent, afforestation and biofuel production become the key strategies, while the role of soil carbon diminishes. If saturating sinks are discounted based on their net present value, the competitive economic equilibrium among agricultural mitigation strategies shifts away from soil carbon sequestration and afforestation and toward more biofuel production. Regardless of the... |

| Many agricultural commodities have industry-funded generic promotion and/or research ("checkoff") programs designed to improve the economic performance of producers. To determine the effectiveness of these programs, the net benefits to producers attributable to activities funded by the checkoff must be separated from those due to other factors influencing commodity markets. One such factor that is very important in many agricultural commodity markets is the effect of government programs. However, studies evaluating the returns to checkoff programs often do not explicitly discuss the impact of pre-existing distortions caused by federal farm programs. Because the distortions caused by farm programs can be quite large, this omission can lead to... |
