AN EVALUATION OF SELECTED DECISION MODELS: A CASE OF CROP CHOICE IN NORTHERN THAILAND AgEcon
Vieth, Gary R.; Suppapanya, Pramote.
This research examines the predictability of a profit maximization model, an expected value-variance utility maximization (E-V) model, and two versions of the target-MOTAD model for modeling risky agricultural production decisions. Model solutions were translated into expected value and variance of farm income for analysis. Direct comparison and chi-square analysis of actual and predicted expected income distributions were used in the analyses. It was concluded that the utility maximization and cash-cost target-MOTAD models predicted distributions of farm income better than the variable-cost target-MOTAD and profit maximization models.
Tipo: Journal Article Palavras-chave: Decision models; Expected utility maximization; Farm income; Profit maximization; Target-MOTAD; Crop Production/Industries.

AN ANALYSIS OF THE IMPACT OF ENERGY PRICE ESCALATIONS DURING THE 1970S ON HAWAII BEEF PRODUCTION AND PRICES AgEcon
Roberts, Roland K.; Vieth, Gary R.; Nolan, James C., Jr..
A quarterly econometric model of the Hawaii beef production sector is estimated. Energy prices influence the model through Hawaii beef and feed prices which are a function of Mainland-to-Hawaii freight rates. Energy prices also influence the decision of whether to allocate feeder animals to feedlots or pasture. Through simulation, it was found that rapidly increasing energy prices after 1973 resulted in a 22 percent reduction in total Hawaii beef production. The composition of production also changed toward more grain fed and less grass fed beef. Given these results, other state and national beef modelers might find it useful to include energy prices in their models.
Tipo: Journal Article Palavras-chave: Livestock Production/Industries; Resource /Energy Economics and Policy.
