| Variety release decisions involve a number of tradeoffs, usually between grower and end-user characteristics as well as significant uncertainties about agronomic, quality, and economic variables. In this study, methodologies were developed to value tradeoffs for grower and end-user characteristics for wheat. The models capture effects of variability in agronomic, quality, and economic variables. The models were applied for three experimental varieties which have since been released and for two hypothetical varieties. Results indicate two of the experimental varieties provide improvements in grower and end-use value over most of the incumbents. Comparison of a risk adjusted portfolio model consisting of characteristics of end-use and grower values... |

| Eighty-nine percent of American households were food secure throughout the entire year in 2005, meaning that they had access, at all times, to enough food for an active, healthy life for all household members. The remaining households were food insecure at least some time during that year. The prevalence of food insecurity declined from 11.9 percent of households in 2004 to 11.0 percent in 2005, while the prevalence of very low food security remained unchanged at 3.9 percent. This report, based on data from the December 2005 food security survey, provides the most recent statistics on the food security of U.S. households, as well as on how much they spent for food and the extent to which food-insecure households participated in Federal and community food... |

| This study focuses on the economics of segregating U.S. non-biotech corn and soybeans for shipments to Japan, the primary export market for U.S. non-biotech grains and oilseeds, as a case study. The purposes of this paper are two-fold: 1) to estimate price premiums that buyers in both the U.S. domestic and Japanese export markets were willing to pay for non-biotech corn and soybeans for the 2000-2002 crops; and 2) to examine who bears the cost of segregation. |

| One of the major trade policy problems identified by U.S. interests, including grower groups, traders, and policymakers, is that of pricing transparency. This has been a gnawing issue generally related to the pricing practices of competitor exporting countries with state trading enterprises (STEs). The transparency problem generally refers to the inability to observe rivals' terms of trade (including price, quality, credit, etc.) and is normally associated with commercial exporters competing against STE rivals. The perception being the less transparent competitors (STEs) would have a strategic advantage. A game theory model of bidding competition was developed to simulate the effects of information asymmetry amongst rivals. A Bayes-Nash equilibrium... |

| Fusarium Head Blight (FHB), commonly known as scab, has been a severe problem for wheat and barley producers since 1993. This study provides an update of economic losses suffered by wheat and barley producers in scab-affected regions in the United States. Emphasis is placed on estimating direct and secondary economic impacts of yield and price losses suffered by wheat and barley producers from 1998 to 2000. Nine states are included in the analysis for three wheat classes. Three of the nine states were also used for the analysis of malting and feed barley. The cumulative direct economic losses from FHB in hard red spring (HRS) wheat, soft red winter (SRW) wheat, durum wheat, and barley is estimated at $870 million from 1998 through 2000. The combined... |

| This article presents a mathematical programming model of wheat cleaning and blending decisions at a country elevator. Simulations are performed to illustrate the sensitivity of cleaning to selected variables, including the value of screenings, transportation costs, and market discounts for excess dockage. In addition, the model is used to assess the impact of including dockage in the grade standards for wheat. |

| Analytical models were developed in this paper to evaluate cost/risk tradeoffs of three alternative procurement strategies in the case of hard red spring (HRS) wheat. Results indicate a naive strategy has the lowest expected cost, but a high probability of not conforming to end-use requirements. Two alternative specifications for the constant share strategy result in higher probabilities of meeting requirements, but at higher costs. The opportunistic strategy results in a higher probability of meeting requirements than either of the other two alternative strategies at a comparable cost. |

| The regional demand for feed grains is not directly observable. This study uses a programming model to derive a demand schedule for feed barley. The model is applied to a major barley producing region (North Dakota and Minnesota) and an important feed deficit region (California). Direct and cross-price elasticities are evaluated, and sensitivity analysis shows the potential impact of improved barley varieties on regional demand. |
