The agricultural value of El Nino-Southern Oscillation (ENSO) phase knowledge is measured in a value-of-information framework using economic models. We examine the value of considering the full distribution of ENSO phase strength effects as opposed to average ENSO phase strength effects, as well as the implications of considering ENSO impacts on the rest of the world (ROW). A stochastic U.S. agricultural sector model linked with a global trade model is used to assess the value of ENSO phase information. When the full distribution of ENSO phase strength is considered, the value of phase information increases twofold with respect to the average ENSO effects. |

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... |

Consumers’ consumption patterns could be affected by food safety information, however, it is more important to consider where the food safety issue occurs. If the food safety issue happens in other countries, in other words, it outbreaks out of the target market, negative information may be beneficial; in contrast, if the food safety issue occurs within the market, results may consistent with previous studies. Based on this assumption, this paper reinvestigates the impacts of AI media coverage and BSE cases on the demand of meat in U.S. market. Estimated results provide supports for our assumption, i.e., AI information has positive effect on poultry and turkey demands in short term, and BSE affect beef demand negatively. |

Systematic approaches to validation of linear programming models are discussed for prescriptive and predictive applications to economic problems. Specific references are made to a general linear programming formulation, however, the approaches are applicable to mathematical programming applications in general. Detailed procedures are outlined for validating various aspects of model performance given complete or partial sets of observed, real world values of variables. Alternative evaluation criteria are presented along with procedures for correcting validation problems. |

Economic feasibility of Texas Blacklands corn production in relation to sorghum, wheat, and cotton is studied. Biophysical simulation generated yield data are integrated with an economic decision model using quadratic programming. Given the various scenarios analyzed, corn is economically feasible for the Blacklands. A crop mix of half corn and half cotton production is selected under risk neutrality with wheat entering if risk aversion is present. Corn and grain sorghum production are highly substitutable. Profit effects attributed to changing corn planting dates are more pronounced than profit changes resulting from altering corn population or maturity class. |

With the increasing research interests in biofuels, global implications of biofuels production have been generally examined either in a partial equilibrium (PE) or general equilibrium (GE) frameworks. Though both of these approaches have unique strengths, they also suffer from many limitations due to complexity of addressing all the relevant aspects of biofuels. In this paper we have exploited the strengths of both PE and GE approaches for analyzing the economic and environmental implications of the U.S. policies on corn-ethanol and biodiesel production. In this study, we utilize the Forest and Agricultural Sector Optimization Model (FASOMGHG: Adams et al. 1996, 2005; Beach et al. 2009), a non-linear programming, PE model for the United States. We also use... |

Agriculture may help mitigate climate change risks by reducing net greenhouse gas (GHG) emissions (McCarl and Schneider, 2000). One way of doing this is that agriculture may provide substitute products that can replace fossil fuel intensive products or production processes. One such possibility involves providing feedstocks for conversion into consumable forms of energy, where the feedstocks are agriculturally produced products, crop residues, wastes, or processing byproducts. Such items may be used to generate bioenergy encompassing the possibilities where feedstocks are used: • to fuel electrical power plants; • as inputs into processes making liquid transportation fuels e.g., ethanol or biodiesel. Employing agriculturally produced products in such a way... |
