A Dynamic Decision Model of Technology Adoption under Uncertainty: Case of Herbicide-Resistant Rice AgEcon
Annou, Mamane Malam; Wailes, Eric J.; Thomsen, Michael R..
Herbicide-resistant (HR) rice technology is a potential tool for control of red rice in commercial rice production. Using an ex ante mathematical programming framework, this research presents an empirical analysis of HR rice technology adoption under uncertainty. The analysis accounts for stochastic germination of red rice and sheath blight to model a profit maximization problem of crop rotation among HR rice, regular rice, and soybeans. The results demonstrate that risk attitudes and technology efficiency determine adoption rates and optimal rotation patterns.

IMPLICATIONS OF RICE BIOTECHNOLOGY ON OPTIMAL RICE CROP ROTATION IN THE MISSISSIPPI RIVER DELTA REGION AgEcon
Annou, Mamane Malam; Thomsen, Michael R.; Hansen, James M.; Wailes, Eric J.; Cramer, Gail L..
Availability of new herbicide-resistant biotech rice varieties may affect traditional rice rotation practices to control red rice and enhance yields. This research evaluates the adoption of biotech rice and its effects on the current practice of crop rotation in the Mississippi River Delta region. The optimal utilization of biotech rice rotation is analyzed using a nonlinear mathematical programming model with mixed integers. Optimal rotation was found to be sensitive to the technology fee, relative prices received by farmers, the effectiveness of red rice control, and a sheath blight penalty on yield for continuous rice production.

Market Impacts of Adopting Herbicide-Resistant Rice in the Southern United States AgEcon
Fuller, Frank H.; Annou, Mamane Malam; Wailes, Eric J..
Herbicide-resistant (HR) rice varieties offer U.S. rice producers a powerful tool for control of red rice infestations. However, improved weed control can shorten crop rotations and boost yields, resulting in expanded rice production and lower domestic market prices. Declining market returns diminish the benefits of HR rice adoption and substantially reduce net returns for nonadopters. More competitive prices increase U.S. rice exports, causing a slight decline in world rice prices. The dependence of the rice marketing loan program on world prices prevents loan deficiency payments from adequately offsetting producers’ market revenue losses. U.S. consumers gain from lower rice prices.
