Traffic flows in the U.S. have been affected by the substantial increase and, as of January 2009, decrease in biofuel production and use. This paper considers a framework to study the effect on grain transportation flows of the 2005 Energy Act and subsequent legislation, which mandated higher production levels of biofuels, e.g. ethanol and biodiesels. Future research will incorporate changes due to the recent economic slowdown. |

A model with omitted resource constraints is suggested as an alternative to a risk aversion model for explaining economic behavior. This paper uses two standard mathematical programming models to further explore this issue. One model is a standard profit maximization linear programming model and the other is a risk averse quadratic programming model with part of the constraints deleted. Theoretical investigation of these models demonstrates that risk aversion can substitute for omitted resource constraints. A small empirical model is then solved under both formulations. With resource constraints deleted, positive risk aversion is necessary to obtain a similar enterprise organization as under profit maximization with complete constraints. These two... |

We employ a game-theoretic principal agent framework to analyze the individual farmer and governmental behavior pre- and post-animal disease outbreak. We examine the gap between the privately optimal and socially optimal levels of ex ante biosecurity investment and then investigate how a well-designed differentiated compensation scheme can close this gap. Our results also show that the privately optimal investment is generally lower than the first best socially optimal level, and a well-designed differentiated compensation scheme conditional on ex ante biosecurity investment can induce private preventive investment at least greater than the second best socially optimal level when the government face constraints, or even increase approaching the first best... |

In this paper, two AI mitigation strategies are examined, quarantine and vaccination. Meanwhile, associated welfare changes are evaluated by using FASOM. Results found that changes of total national welfare of U.S are insignificant with or without vaccination. Once comes to livestock producers, impacts become significant although magnitudes are small. For example, under 20% demand shocks, vaccination strategy dominates no vaccination at the production, market and national level. However, vaccination has no advantage when there is no demand shifts. |

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. |

Panel models with random effects are used to estimate how climate influences in-stream surface water supply, municipal water demand, crop yields and irrigation water use. The results are added into TEXRIVERSIM, a state wide economic, hydrological, environmental and inter-basin water transfer (IBTs) investment model, through the objective function and hydrological constraints. A climate change related scenario analysis from the Global Circulation Models (GCMs)--Hadley, Canadian, BCCR and NCAR with SRES scenarios A1B, B1, and A2 indicates that inter-basin water transfers not only greatly relax water scarcity problems for major cities and industrial counties, but also create growth opportunity for Houston. However, while destination basins receive 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. |

A dry year irrigation suspension has been proposed as a way of reallocating water when aquifer levels are low for the Texas Edwards Aquifer. Under this program, farmers would be paid to suspend irrigation to allow more spring flow or nonagricultural pumping. When irrigation is suspended in the east, springflow response is markedly larger than when suspended in the western portions of the aquifer. Most acreage participates when a $90 per acre payment is offered before the cropping season. Considerably higher payments are needed and less water saved for a suspension program instituted during the cropping season. |

A multiperiod regional mathematical programming model is used to evaluate the potential economic impacts of global climatic change on the southern U.S. forestry sector. Scenarios for forest biological response to climate change are developed for small and large changes in forest growth rates. Resulting changes in timber supply have economic impacts on producers and consumers in forest products markets, both nationally and regionally. Conclusions include outer dimensions of global climate change impacts and potential effects of smaller biological responses on the forestry sector both nationally and in the U.S. South. Relative impacts are found to be larger for producers than for consumers, and southern producers experience relatively greater changes in... |
