| The events of 1999 highlight the importance of the need for identity preservation (IP) of products that result from genetic modification. In April of 1999, Archer Daniels Midland Co. and A. E. Staley Co. announced that they would not accept product that was not approved for export to the European Union. By the time the 1999 harvest arrived, decision makers in the grain marketing industry realized the nature of their business had dramatically changed in just one growing season. In particular, they needed to preserve the identity of all grains and oilseeds intended for European and Japanese markets. During the remainder of the 1999 growing season, consumer concern about the safety of genetically modified organisms (GMOs) increased. The need for IP represents... |

| Mathematical programming analysis has been quite effective for commercial farm planning in developed countries, but less so for subsistence farms in developing countries. In particular, it is difficult to reproduce the level of diversification observed on subsistence farms using a simple profit maximization framework. This paper proposes an alternative to the minimum consumption requirement approach for modeling subsistence farming households by treating consumption explicitly through a demand system motivated by Cobb-Douglas utility. A typical, linear programming-based production system is incorporated, allowing for the production of crops and livestock subject to constraints on resource availability. The approach successfully predicts consumption... |

| A 40-region nonlinear programming model of a cooperative livestock feed production and distribution system, including possibilities for on-farm processing, is used to compare system organization and performance given two pricing strategies. Use of one price regardless of location results I higher average costs to patrons than pricing products to reflect cost to each region. Transportation costs are increased using uniform pricing. Cost effects are small and may be offset by other benefits of uniform pricing. |

| Procedures are needed to evaluate the benefits of the provision of information. This paper shows how to apply a money metric definition of the value of information for this purpose. The application is to microeconomic input choices for agricultural production, and the information to be valued concerns the effect of fertilization on sorghum yield. In this paper application both output price and output level are stochastic, and the probability distribution of output is affected by the chosen level of fertilizer. |

| Public and private electric utilities are considering co-firing biomass with coal as a strategy to reduce the levels of CO2, SO2 and NO, in stack emissions, as well as a response to state legislative mandates requiring the use of renewable fuels. This analysis examines the conditions under which biomass co-firing is economically feasible for utilities and woody biomass producers and describes additional environmental and community benefits associated with biomass use. This paper presents a case study of woody biomass production and co-firing at the Northern Indiana Public Service Company (NIPSCO) Michigan City Unit No.12 power plant. A Salix (willow) production budget was created to assess the feasibility of plantation tree production to supply biomass to... |

| Three hog genotypes are simulated to determine how producer profits, economically optimal slaughter weights, and carcass component weights change under three pricing models. Live weight pricing pays more for the fatter barrows whereas a three component (separate payments for fat, lean, and byproducts) and six component (separate payments for major primal cuts, other lean, fat, and byproducts) pricing system pay more for the leaner gilts. Implications for selection of genetic stock and pricing system are presented. |
