| Policy makers are searching for viable strategies to produce alternative energies; the agricultural sector can become an important supplier of renewable energy. The paper will develop the IFECO (integrated farm energy cogeneration) approach, a conceptual model of farm though as it were an "island economy"a a net energy exporter as the energy output exceeds the direct energy (cultivation, cropping, plant protection, transport, harvesting, storage) and indirect energy (fertilizer, pesticide, machinery, plantationforce, others) used in sunflower cultivation. IFECO is based on the cogeneration that is the production of different energies from a single agricultural commodity to achieve the three targets that make this project sustainable: i) economic... |

| This study evaluated the impacts of farm size and stochastic return variability on no-till (NT) rice profitability at the whole-farm level. Mixed integer programming was used to determine optimal machinery complements, fuel consumption, and machinery labor requirements for conventional till (CT) and NT rice-soybean farms of 1200, 2400, and 3600 acres in size. Crop yields, market prices, and prices for key production inputs were simulated to construct stochastic whole-farm net returns for each farm size under CT and NT management, and both first and second degree stochastic dominance analysis were used to rank cumulative distribution functions of whole-farm returns according to specified risk preferences. The results indicate NT farms exhibit second degree... |

| The Oklahoma Agricultural Bank Simulation Game (Ag Bank Sim) is a software based, experiential learning tool through which participants historically have learned key financial, economic, and banking lessons. The game offers a “real world” experience in which management decisions affect institutions interacting in a geographic market, enhancing understanding of the complex, competitive environment within which commercial banks operate. A new Internet version of the game has been developed, allowing participants to play Ag Bank Sim in a virtual environment. This poster highlights features of the game and reports results of pre and post tests of undergraduate students playing the game at Louisiana State University and Oklahoma State University in the spring... |

| The simulation of commodity prices has been undertaken using a myriad of techniques, with some omitting the cyclical component and others ignoring the presence of inter-temporal relationships expressed as autoregressive errors. This study examines the periodicity of cattle prices and the modeling of the cattle cycle for simulation purposes. The AIC criterion is used to determine lengths of various cycles to be included in a harmonic model, with a chained modeling approach providing the best representation of the cattle cycle. |

| The arable crop sector in Spain is highly dependent of the Community subsidies and account for 33% of total transfers received by the Community. Then, it is expected that the introduction of the Single Farm Payment (SFP) will drive important changes in the arable crop production in Spain. The quantitative assessment of the SFP impacts on the arable crop sector in Spain is the overall objective of this paper. To achieve this goal, an econometric, dynamic, multi-product and partial equilibrium commodity model has been built disaggregating between irrigated and non-irrigated land use for cereals called Spanish Econometric Simulation of Agricultural Policies (SESAP). Results indicated that the introduction of the SFP has only induced considerable changes... |
