Scientific inquiry is increasing our knowledge of plant and animal genomics. The ability to specify heterogeneous production processes, to sort agricultural inputs by genotype, or to guide breeding programs to satisfy specific markets based on genetic expression may potentially increase producer and consumer benefits. This research develops a decision analysis framework to assess the expected value of genetic information. Expected returns are evaluated both in the presence of, and without, genetic trait information. Potential gains in the value of information can be quantified as research unravels the linkages between genetics and crop and animal performance and quality. An application to cattle feeding indicates potential gains to developing markets... |

Agriculture operates in an uncertain environment. Yields, prices, and resource usage can change dramatically from year to year. However, most analyses of the agricultural sector, at least those using mathematical programming methods, assume decision making is based on average yields, ignoring yield variability. This study examines how explicit consideration of stochastic yield outcomes influence a sector analysis. We develop a model that can be used for stochastic sector analysis. We extend the risk framework developed by Hazell and others to incorporate discrete yield outcomes as well as consumption activities dependent upon yield outcomes. An empirical application addresses a comparison between sector analysis with and without considerations of the... |

The purpose of this report is to assess the role of agriculture in the North Dakota economy. This analysis is both statewide and regional in perspective (data are provided for each of the state's eight planning regions). Key indicators used in the analysis include sales for final demand (i.e., sales to out-of-state markets), gross business volume (gross receipts), gross state product (value added), and direct employment for each economic sector. The analysis reveals that, although its role in the North Dakota economy has been reduced in a relative sense, agriculture remains a cornerstone of the state economy and remains the largest goods and services exporting sector. While agriculture accounts for smaller shares of state sales for final demand, gross... |

Teaching efficiency is investigated for the nine departments in the College of Agriculture, Food Systems, and Natural Resources at North Dakota State University. Using Data Envelopment Analysis, departments are compared to their College peers in converting teaching faculty and teaching funds into three teaching outputs: student credit hours generated, undergraduate majors, and graduate students. Most departments are efficient in the technical conversion of inputs to outputs under variable returns to scale. Scale effects are evident, indicating some departments consistently extract higher average productivity from inputs in servicing undergraduate majors, graduate students, and in generating student credit hours. |

Nevada ranks third in the world in gold production. In order to operate the massive open pit gold mines, the State of Nevada granted mining companies a temporary permit to pump groundwater from near the open pits and dispose of it. Certain instream flows have nearly doubled relative to average historical flows in recent years. Following pit closure, surface flows will likely decline from historical levels. This study measures the impacts of these changing water supplies on downstream agricultural and recreational users. We argue that the creation of temporary changes in water rights for the downstream users would likely mitigate future losses both groups are expected to experience. |

Markets for agricultural products may be inefficient when signals do not adequately reflect product characteristics important to market participants. Although preferences can be explicitly stated through price premiums or characteristic values can be determined via hedonic methods, the problem is compounded when product quality information is costly to obtain. Bundling of quality traits by variety can serve to signal product quality. A procedure is developed in this paper to derive the value of different varieties in meeting buyer demands. An application to the hard red spring market wheat both validates the ability of the procedure to distinguish among varieties, as well as provides empirical support to the existence of Akerlof's lemon market in the... |

Ranch production and marketing decisions occur sequentially over time as uncertainty regarding future events is resolved. The model developed in this paper explicitly considers the sequential nature of ranch decision making in determining optimal strategies for calf retention and production. A number of optimal decisions are reported for each period, conditional upon the state of nature and expected future events at that decision node. Solutions are found to be dependent on observed and expected output prices. |

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... |

Bid prices were elicited for standard-label cookies, muffins, and potato chips and those identified as not including genetically modified (GM) ingredients using an experimental auction. Including a statement that the product did not include GM ingredients increased bids over those offered for standard-label products. Providing negative-biased information about the impact of GM crops on the environment increased the risk participants associated with GM foods, and positive-biased information decreased perceived risk. Overall, providing impact information, whether positive- or negative-biased, increased bids for products presumed GM. The influence of information bias on bids varied among selected participant groups, supporting the presence of uniquely... |

One of the most uncertain resources for a western beef cattle ranch is the availability of reliable spring forage. The impact on ranch equity position and income variability of investments in crested wheatgrass seedings designed to stabilize spring forage supplies is examined. Expected ending net worth under stochastic forage production and cattle prices is maximized subject to secondary safety-first objectives. Seedings increase expected ending net worth and increase annual net ranch incomes after plant establishment. |
