| This article develops a dynamic micro-economic land use model to identify the cost-effective allocation of cropland for traditional row crops and perennial grasses and the mix of cellulosic feedstocks needed to meet pre-determined biofuel targets over the 2007-2022 period. Yields of perennial grasses are obtained from a biophysical model and together with county level data on costs of production for Illinois are used to examine the implications of these targets for crop and biofuel costs, greenhouse gas emissions, and nitrogen use. The economic viability of cellulosic feedstocks is found to depend on their yields per acre and the opportunity cost of land. The mix of viable cellulosic feedstocks varies spatially and temporally with corn stover and... |

| We analyze the design of water pricing rules emerging from farmers' lobbying and their implications for the size of the lobby, water use, profits and social welfare. The lobbying groups are the adopters of modern irrigation technology and the non-adopters. The pricing rules are designed to meet budget balance of water provision; we considered (i) a two-part tariff composed of a mandatory per-acre fee plus a volumetric charge and (ii) a nonlinear pricing schedule. Our results show that under either pricing schemes, farmers can organize and affect the outcome of the water schedule design. When only a volumetric fee is levied, the budget balance constraint prevents lobbies from influencing the design of the pricing scheme. In terms of expected welfare, 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... |

| An integrated watershed management framework that combines economic, hydrologic and GIS modeling is developed to study cost effective land retirement in multiple watersheds to achieve off-site sediment reduction goal. This integrated framework examines two alternative standards-a uniform standard under which each watershed is required to achieve the same sediment reduction goal and a non-uniform standard under which marginal cost of sediment abatement is equal across watersheds. Furthermore, for each standard, costs of abatement under two alternative rental instruments based on marginal cost of sediment abatement ($/ton) and uniform payments per acre ($/acre) are examined. Then the cost effectiveness of the four policy options (uniform standard with $/ton... |

| A micro-level model of farmer decision making is developed to examine the extent to which uncertainty about potential yields influences the value of site-specific technologies. The economic and environmental benefits of these technologies arise from two sources: information gathering and variable-rate nitrogen application is higher on fields with low average potential yields, high spatial variability, positively skewed potential yield distributions, responsive yield to nitrogen, and low uncertainty. Variable-rate application decreases nitrogen use by reducing the extent of overapplication. However, in the presence of uncertainty about potential yields, the incentives to overapply nitrogen irrespective of the method of application, uniform of variable... |

| EPA-sponsored voluntary pollution reduction programs (VPR) have gained increased prominence in U.S. environmental policy. However, as commitments to these programs are not enforceable by design, the empirical literature has mostly focused on studying the motives for their adoption and their efficacy in curbing pollution. This paper seeks (i) to shed light on the bi-directional links between participation in a VPR and adoption of firm-structured environmental management strategies (EMS), and (ii) the joint impact of VPRs and EMS adoption on the environmental performance of participant firms. Our econometric analysis reveals that participation in the 33/50 program, helped spur the adoption of Total Quality Environment Management (TQEM), which in turn had a... |

| We develop a stylized model of fuel markets in an open economy to analyze the impact of ethanol policy on social welfare and greenhouse gas (GHG) emissions. The policies considered here include the $0.51 per gallon blender’s subsidy for ethanol and the import tariff of $0.54 per gallon on sugarcane ethanol. Our analysis shows that the combined subsidy and tariff policy decreases welfare by about $3.6 billion relative to a non intervention policy. Furthermore, there are no GHG mitigation benefits since GHG emissions show a slight increase (0.08%) when both policies are in place. |

| This paper uses stylized analytical and numerical general equilibrium models to evaluate the welfare impacts of alternative policies for reducing nitrogen run-off from agricultural production in an open economy while recognizing the presence of distortionary agricultural support subsidies and factor income taxes. The alternative policies examined here are a nitrogen run-off tax, a nitrogen run-off reduction subsidy, a tax on the production of agricultural goods, a "two-part" instrument - a combination of the second and the third policies, and land retirement. The paper uses an analytical model to express the welfare impacts of each policy into several components and compares these components across alternative policies. From the analytical model the paper... |
