| This study provides a framework to value investment strategies to mitigate possible agro-terrorism occurrences in the food supply chain and to determine where these investments would reduce the most risk. This framework is applied to two food sectors that could be at risk: milk and green onions. Stochastic optimization is used to determine the costs and risk premiums of alternative tracking strategies. The real options method along with a portfolio of options, also referred to as the "tomato garden" framework, is used to determine where and when alternative intervention strategies should be implemented to reduce the most risk. Finally, policy implications are derived on the cost-risk tradeoffs, probability of attacks, and containment efforts if there... |

| An important characteristic in the malting barley market is the multitude of quality variables which affect the value of particular samples. The purpose of this study was to estimate implicit (or hedonic) prices for selected quality factors. An econometric model was used to analyze factors affecting the variability in malting barley prices, and to estimate implicit prices for plumpness and protein. The results indicate that a change may be evolving in the price determination process for malting barley. In particular, the feed grains sector has had increasingly less effect on malting barley prices in recent years. |

| One of the impacts of higher prices along with greater volatility in futures, basis and spreads is that there is pressure for greater use of cash contracts for grain. There is a wide array of cash contracts with varying terms that pose major strategic alternatives for buyers and the marketing system, particularly as buyers seek to use contracting as an element of risk mitigation. Durum is a crop where many of these issues and challenges are apparent. Durum is more risky than competing crops with greater price, yield and quality risk. And in contrast to competing crops, futures do not exist, cross hedging is poor and forward contracting has been used minimally. There are three purposes of this article: Provide a survey of contract terms used in grain... |

| Development and organization of procurement strategies have escalated in importance with maturity of the food processing industry, as well as with the prospect of greater choice attributable to variety development and information technology. Conventional alternatives for procurement range from spot purchases with specifications for easily measurable characteristics, to varying forms of strategies with pre-commitment. In the case of grains these choices are complicated by two factors. First, there is intrinsic uncertainty associated with end-use qualities that are not easily measurable. Second, grain prices and therefore procurement costs vary spatially due to competing market regions. Thus, shifting origins may involve higher cost due to having to bid... |

| A common and noteworthy application of auctions and bidding is that of tendering for imports, used for both price determination and the allocation of purchases among sellers. In this study we develop a model to evaluate bidding strategies and competition and apply it to Egyptian oilseeds imports. Generally, bids could be explained with a relatively high degree of confidence using accessible data. In addition, there appear to be groups of bidders characterized by differences in their bid functions. These statistical results were used to determine optimal bids and evaluate the effects of several critical variables. The results are particularly interesting for understanding sellers' bidding strategies and competition among rivals, as well as impacts of... |

| The costs of delays for shipping commodities on the Mississippi River are important and adversely impact growth in shipments. Lock and dam expansion requires substantial capital investment and an extended time period to complete. This study analyzes delay costs and the competitive position of grain shipments on the Mississippi River system. A spatial optimization model of the world grain trade was developed. Results indicated that without expansion in barge capacity, delay costs in 2020 would increase on each reach, with some up to $1.08/mt. Expansion results in reduced delay costs. Barge demand is also impacted by rail capacity. Finally, expanding the locks would result in a re-allocation of shipments among modes, reaches, and ports,... |

| Development of genetically modified crops is challenging the functions of the grain marketing system with many participants arguing for Identity Preservation (IP) systems prior to release of GM varieties. In this study, a stochastic optimization model was developed to determine optimal testing strategies. The model chooses the optimal testing strategy that maximizes utility (minimizes disutility) of additional system costs due to testing and rejection and allows estimation of the risk premium required for sellers to undertake a dual marketing system with GM/Non-GM segregations over the current Non-GM system. Elements of costs (testing costs, rejection costs, and risk premium) were estimated for a base model representing a grain export chain. The model... |

| Ethanol is one of the fastest growing industries in the U.S. agricultural sector. This study estimates factors that impact location decisions by new ethanol plants using logistic regression analysis and spatial correlation techniques. The results indicate that location decisions are impacted by the agricultural characteristics of a county, competition, and state-level subsidies. Spatial competition is particularly important. Existence of a competing ethanol plant reduces the likelihood of making a positive location decision and this impact decreases with distance. Finally, state-level subsidies were significant and a very important variable impacting ethanol location decisions. |

| In this study, the strategic impacts of input-output price relationships on end-users' demands for futures and/or options are analyzed. An analytical model is developed based on mean-variance utility and extended to account for the impact of output prices and the inclusion of both futures and/or call options in the portfolio. This study makes several contributions to the literature on risk management in agriculture. First, its focus is on end-users and captures their unique characteristics. Second, it explicitly captures the correlation between input-output prices on hedging strategies. Finally, it incorporates options into a portfolio model. The analytic model was applied to the bread baking industry, an important agribusiness processor, which is... |

| Increased concerns over the quality of wheat in domestic and export markets has focused attention on the consistency of wheat quality. This study utilized three measures to examine the effect of variability in characteristics on the milling value of wheat. Distributions and correlations for wheat quality characteristics were estimated from U.S. wheat export data from 1985-1997. Effects of variability of wheat characteristics on the value of wheat to the miller for each of the three measures were estimated using a simulation model. U.S. No. 1 exports of Hard Red Spring (HRS) had higher value to millers on each of the three measures (net wheat, millable wheat index, and value added in milling) than did exports of No. 2 or better (OB). However, the value... |
