| The control of agricultural nonpoint source pollution is emerging as a priority of state and national pollution control programs. Best management practices (BMPs) are often proposed as a method of control. Many BMPs are perceived by farmers as having economic disadvantages when compared to conventional management systems. In the absence of tougher environmental restrictions on farmer behavior and complete observability of individual farmer actions, it may be necessary to provide economic incentives to encourage farmer adoption of BMPs within environmentally sensitive watersheds. This study investigates the use of a group incentive contract to encourage adoption of BMPs. The idea behind the group incentive contract is to compensate farmers for actual... |

| The paper demonstrates a group incentive program to encourage farmer adoption of best management practices. It is demonstrated that the best management practices may not actually reduce farm profits but may increase farm profits and reduce environmental pollution. This may bring about a win-win situation for sponsor, the farmer participating in the program, and the society as a whole. The results show that the farmers subjective beliefs about response of corn yields and profits to nitrogen application differ from the simulated responses which in turn results in the willingness-to-Accept for adoption best management practices significantly higher than the expected program payments. The program could be implemented as an educational effort to... |

| An option to mitigating flood damages in the Red River Basin is the concept of using hundreds or thousands of ‘micro-basin’ storage areas comprised of roads and adjacent lands to retain a sufficient volume of water over a reasonable period in the spring to lower the flood crest heights on streams and rivers throughout the basin. This concept has been referred to as the Waffle. The present value of costs and benefits of implementing, maintaining, and operating the Waffle were estimated for a 50-year period. Costs included land enrollment expenses, landowner payments, infrastructure modifications and installations, and maintenance and administrative overhead. Data relating river crest heights with probability of flood occurrence and expected damages to... |

| Co-products of processing agricultural commodities are often marketed through private transaction rather than through public markets or those in which public transaction information is recorded or available. The resulting lack of historical price information prohibits the use of positive time series techniques to estimate demand. Demand estimates for co-products are of value to both livestock producers, who obtain them for use in livestock rations, and processors, who must sell or otherwise dispose of them. Linear programming has long been used, first by researchers and later as a mainstream tool for nutritionists and producers, to formulate least cost livestock rations. Here it is used as a normative technique to estimate step function demand... |

| Many value-added practices cannot be observed by feeder cattle buyers. Third-party verification can decrease market inefficiency associated with this asymmetric information. We evaluate the effectiveness of a verification program, the Oklahoma Quality Beef Network, in increasing received prices. We estimate the value of verification, weaning, vaccinating, certification and phenotypic traits of feeder cattle at Oklahoma auctions. Results indicate that the OQBN program adds $2.39 to $5.74/cwt. Vaccinating calves adds $1.44/cwt, and weaning calves adds $2.05/cwt. Differential values for lot size, average weight, hide color, frame size, conditioning, Brahman influence, gender and other characteristics are also reported. |

| Switchgrass, a warm-season perennial grass, native to the region, has received considerable interest for its potential role as a dedicated feedstock for cellulosic-based bio-fuels. This research examined the farm-gate price needed for switchgrass to provide per-acre net returns equal to those obtained from traditional crops in south central North Dakota. Future production costs for switchgrass and net returns from traditional crops were estimated for three soil productivity classes and also were developed to reflect the historical revenue and cost patterns associated with producers who are typically more or less profitable (i.e., average net return per acre) than regional averages. Prices were calculated using an annualized equivalent analysis of... |

| We examine the efficiency of current flood risk allocation and the use of flood easements as a means of reallocating flood risk and reducing total flood damages in large river floodplains. Changes in agricultural floodplain land use and levels of crop insurance coverage as the risk of flooding changes are simulated using mathematical programming. The net benefits of flood easements to a portion of the Lagrange Reach of the Illinois River region are then simulated. Our results indicate that flood easements may provide positive net benefits. This positive result stems primarily from the decreased risk of flooding for non-inundated agricultural levee districts, rather than from reduced municipal flood damages. Our results are robust to changes in the... |

| The purpose of this study was to forecast grain and oilseed shipments through the Mississippi River system and to analyze impacts of delay costs. The focus is on the world grain trade and expected changes in response to a multitude of evolving competitive pressures and structural changes. The model is a spatial optimization model of the world grain trade. Important parameters are forecasted and used to evaluate changes in flows through specific logistical channels. Projected import demands are based on consumption functions estimated using income and population and accounting for intercountry differences in consumption dependent on economic development. Each of the competing supply regions and countries were represented by yields, area potential that... |

| Grain quality is typically measured via several attributes. As these attributes vary across shipments and time, grain quality can be described using multivariate probability or frequency distributions. These distributions are important in modeling blending opportunities inherent in various grain shipments. For computational reasons, it is usually necessary to represent these distributions with a small set of discrete points and probabilities. In this analysis, we suggest a representation method based on Gaussian quadrature. This approach maintains the blending opportunities available by preserving moments of the distribution. The Gaussian quadrature method is compared to a more commonly used representation in a barley blending model. |

| A group incentive program to encourage farmer adoption of best management practices is simulated for a typical watershed in central Illinois. The incentive payments, program costs and environmental impacts of the program are simulated. The results show that the best management practices may not actually reduce farm profits but may increase farm profits and reduce environmental pollution. The sponsor in most cases may not have to pay anything under the incentive contract. This may bring about a win-win situation for the sponsor, the farmer participating in the program, and society as a whole. The program could be implemented as an educational effort to demonstrate the benefits of sound management practices. |
