Hurricanes and Possible Intensity Increases: Effects on and Reactions from U.S. Agriculture
Provedor de dados: 31
Autores: Chen,   Chi-Chung; McCarl,   Bruce A.
Hurricanes have caused substantial damage in parts of the U.S. Damages are increasing, perhaps as part of a natural cycle or perhaps in part related to global warming. This paper examines the economic damages that hurricanes cause to U.S. agriculture, estimates the increased damage from an increase in hurricane frequency/intensity, and examines the way that sectoral reactions reduce damages. The simulation results show that hurricanes and associated adjustments cause widespread damage and redistribute agricultural welfare. We find that crop mix shifts of vulnerable crops from stricken to nonstricken regions significantly mitigate hurricane damages.

What does the introduction of energy crops mean for the crop mix and cellulosic ethanol plant location in Louisiana?
Provedor de dados: 31
Autores: Mark,   Tyler B.; Darby,   Paul M.; Salassi,   Michael E.
This paper examines the introduction of energy cane and switchgrass in the available crops for production in the Louisiana Sugarcane Belt. Employing an optimal crop mix model net returns over variable costs for each county is maximized.  Furthermore, this paper determines the optimal processing plant location based upon transportation of the biomass produced to one central location for processing.

Aggregation and Calibration of Agricultural Sector Models Through Crop Mix Restrictions and Marginal Profit Adjustments
Provedor de dados: 31
Autores: Wiborg,   Torben; McCarl,   Bruce A.; Rasmussen,   Svend; Schneider,   Uwe A.
All agricultural sector models must deal with aggregation and calibration somehow. The aggregation problem involves treating a group of producers as if they all responded in the same way as a single representative unit. The calibration problem concerns making a model reproduce as closely as possible an empirically observed set of decision maker actions. This paper shows how both calibration and aggregation are addressed through crop mix restrictions combined with marginal profit adjust-ments.
