BOOTSTRAPPING IN VECTOR AUTOREGRESSIONS: AN APPLICATION TO THE PORK SECTOR AgEcon
Susanto, Dwi; Zapata, Hector O.; Cramer, Gail L..
Standard bootstrap method is used to generate confidence intervals (CIs) of impulse response functions of VAR and SVAR models in the pork sector. In the VAR model, the bootstrap method does not produce significant different results from Monte Carlo simulations. In the SVAR analysis, on the other hand, the bootstrap CIs are significantly different from Monte Carlo CIs after a six period forecast intervals. This suggests that the choice of method used to measure reliability of IRFs is not trivial. Furthermore, bootstrap CIs in SVAR model seem to be more stable than MC CIs, which tend to be wider in the longer horizons.

DOUBLE-HURDLE MODEL WITH BIVARIATE NORMAL ERRORS: AN APPLICATION TO U.S. RICE DEMAND AgEcon
Gao, Xiaoming; Wailes, Eric J.; Cramer, Gail L..
Per capita rice consumption in the U.S. has doubled over the past decade. The effects of social and demographic variables on the household's rice consumption decisions are analyzed along with income and price variables. A double-hurdle model is used to solve simultaneously the consumer decisions whether to purchase rice and how much. The joint decision hypothesis is tested and accepted. The non-normal distribution of error terms may be responsible for possible bias in the empirical test of the joint decision hypothesis. The hyperbolic sine transformation is used to correct the problem in this study prior to testing the joint decision hypothesis.
Tipo: Journal Article Palavras-chave: Double hurdle; Non-normal error distribution; Rice demand; Crop Production/Industries; Demand and Price Analysis.

IMPACT OF PESTICIDE REGULATORY POLICIES ON U.S. RICE PRODUCTION AgEcon
Guru, Manjula V.; Wailes, Eric J.; Cramer, Gail L..
This paper examines the costs and benefits of pesticide regulations on US rice production. Benefit - cost analysis of FIFRA (The Federal Insecticide, Fungicide, and Rodenticide Act) has been done taking into consideration the externality costs associated with the Endangered Species Act and the Worker Protection Standard, for which compliance under FIFRA has become mandatory since 1990.

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.
