| 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... |

| This paper extends an integrated framework that combines economic, environmental and GIS modeling to evaluate the cost effectiveness of land retirement programs. The modeling framework is applied to the Lower Sangamon Watershed in Cass County of Illinois to examine the economic costs and environmental benefits of three land retirement scenarios: land actually enrolled in the Illinois CREP, land selected by a land rental cap mechanism and land identified by a least cost model. We find that land retirement in the watershed successfully achieved the program goal of 20% sediment abatement. However, in achieving the same level of sediment abatement, the costs of actual land retirement are 1.3 times and 2.1 times of those in a land rental cap mechanism and a... |

| 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 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... |

| 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... |

| An integrated watershed management framework that combines detailed spatial biophysical attributes of land with a hydrologic model and an economic model is developed to study the cost-effective enrollment of land in the Conservation Reserve Enhancement Program (CREP). Compared with previous related studies that assumed exogenous sediment deposition coefficients related only to site specific characteristics, this research explicitly considers endogenous sediment deposition coefficients, that are determined by landuse decisions made by all land parcels in the run-off path, in determining land rental offers. The modeling framework is applied to one of the eligible watersheds, Court Creek, in Illinois. We find that the optimal targeting of land enrollment is... |

| Biofuels have been promoted to achieve energy security and as a solution to mitigating climate change. This research presents a framework to examine the extent to which biofuel mandates and subsidies reduce gasoline consumption and their implications for the food and fuel prices. A dynamic, multi-market equilibrium model, Biofuel and Environmental Policy Analysis Model (BEPAM), is used to estimate the effects of these policies on cropland usage between food crops and fuel crops and food and fuel prices, and to analyze the incentives provided by alternative policies for the mix of biofuels from corn and various cellulosic feedstocks that are economically viable over the 2007-2022 period. The provision of biofuel subsidies that accompany the mandate under... |

| This paper develops an endogenous growth model which links pollution to ineffective input-use, which can be reduced through conservation capital investment. It derives the conditions under which individual preferences for environmental quality and private investment in conservation capital can lead to non-decreasing environmental quality and balanced growth in an unregulated and in a regulated regime. In the absence of regulation, balanced growth can lead to improvement in environmental quality as long as the rate of growth is low. The extent to which the growth rate is low depends upon preference for environmental quality, interest and discount rates, productivity of conservation capital, and price of the polluting input. Under an emissions tax regime,... |
