| A watershed based model, the Soil and Water Assessment Tool (SWAT), along with transfer coefficients is used to assess alternative principles of allocating nutrient load reduction in the Raccoon River watershed in central Iowa. Four principles are examined for their cost-effectiveness and impacts on water quality: absolute equity, equity based on ability, critical area targeting, and geographic proximity. Based on SWAT simulation results, transfer coefficients are calculated for the effects of nitrogen application reduction. We find both critical area targeting and downstream focus (an example of geographic proximity) can be more expensive than equal allocation, a manifestation of absolute equity. Unless abatement costs are quite heterogeneous across the... |

| We examine the social efficiency of alternative intertemporal permit trading regimes. Banking with a 1-to-1 ratio and with a non-unitary intertemporal trading ratio (ITR) are compared with each other and with the no-banking permit trading regime. The more industry-wide shocks vary, and/or the more they are negatively correlated across time, the more efficient is a bankable permit regime. When the slope of the benefit function is greater than the slope of the damage function, banking with ITR=1+r is more efficient than a no-banking regime. Banking with ITR=1 can be more efficient than a no-banking regime. However, whether ITR=1 or ITR=1+r is better depends on the covariance structure of the shocks and the benefit and damage functions. |

| Land use changes to sequester carbon also provide "co-benefits," some of which (for example, water quality) have attracted at least as much attention as carbon storage. The non-separability of these co-benefits presents a challenge for policy design. If carbon markets are employed, then social efficiency will depend on how we take into account co-benefits, that is, externalities, in such markets. If carbon sequestration is incorporated into conservation programs, then the weight given to carbon sequestration relative to its co-benefits will partly shape these programs. Using the Conservation Reserve Program (CRP) as an example, we show that CRP has been sequestering carbon, which was not an intended objective of the program. We also demonstrate that more... |

| In this paper, we study the social efficiency of private carbon markets that include trading in agricultural soil carbon sequestration when there are significant co-benefits (positive environmental externalities) associated with the practices that sequester carbon. Likewise, we investigate the efficiency of government run conservation programs that are designed to promote a broad array of environmental attributes (both carbon sequestration and its co-benefits) for the supply of carbon. Finally, policy design and efficiency issues associated with the potential interplay between a private carbon market and a government conservation program are studied. Empirical analyses for an area that represents a significant potential source of carbon sequestration and... |

| We investigate the value of carbon sequestration in a dynamic model, demonstrating that it is only a fraction of the value of emission abatement unless the sequestration, the natural decay rate of carbon and the discount rate. We also show that to optimally reduce the carbon stock, sinks should be utilized as early as possible. Further, we propose and assess three mechanisms to efficiently introduce sequestration into a carbon permit trading market, a pay-as-you-go system. We show that, although the three mechanisms may not be equally feasible to implement, they are all efficient. |

| As Congress develops new farm legislation, some are lobbying for a new partnership between U.S. taxpayers and farmers. In exchange for an annual transfer of $10 to $20 billion from taxpayers to agriculture, farmers would do much more to enhance environmental quality. An attractive feature of a new partnership is that paying for an improved environment provides a clear and justifiable rationale for farm program payments, something that is lacking under current farm programs. By changing management practices and land use, farmers can provide cleaner water, cleaner air, better wildlife habitat, lower net greenhouse gas emissions, and improved long-run soil quality. Private profit maximizers largely ignore the value of these environmental goods. Hence, the... |

| This study investigates the carbon sequestration potential and co-benefits from policies aimed at retiring agricultural land in the Upper Mississippi River Basin, a large, heavily agricultural area. We extend the empirical measurement of co-benefits from the previous focus on environmental benefits to include economic transfers. These transfers have often been mentioned as a co-benefit, but little empirical work measuring the potential magnitude of these transfers has previously been undertaken. We compare and contrast five targeting schemes, each based on maximizing different physical environmental measures, including carbon sequestration, soil erosion, nitrogen runoff, nitrogen leaching, as well as the area enrolled in the program. In each case, the... |

| This paper analyzes the efficient design of green payments. Green payments can generate environmental benefits and support farmers' income. We extend a standard adverse selection model by incorporating dual policy goals into the design of green payments: conservation and income support. We also introduce heterogeneity into conservation efficiency type. The results of our dual-goal model and the standard adverse selection model are significantly different. The differences arise from two aspects. First, since farmers may receive green payments for conservation, or income support, or both, the incentive structure in the standard adverse selection model can be significantly altered. Second, information rent is no longer just a cost to induce truthful... |

| As the United States begins to move towards putting an economic value on reducing greenhouse gas (GHG) emissions, the need for improved accounting standards becomes acute. Lifecycle analysis (LCA), which involves the systematic collection and interpretation of material flow in all relevant processes of a product, has become the accepted procedure to use to determine greenhouse gas emissions of products ranging from transportation fuels, to building materials, to food production (Farrell et al., 2006; Hill et al., 2006; Owen, 2004). The basic motivation of LCA is that, to conduct a fair assessment of the environmental impacts of a product, it is necessary to take into account all of the processes throughout the product’s lifespan, including the extraction... |
