The MODERE, the Ministry of the Environment Irrigation Decision Model, is a simulation tool whichuses mathematical programming methods to reveal the implicit multiattribute objective function lyingbehind the observed cropping decision. The model takes different criteria such as profit...

Rapidly declining gasoline prices from their record high during the summer of 2008,while ethanol prices remained relatively high, made it difficult for many bio-fuel policymodelers to fully explain the impacts of U.S. bio-fuel policies on fuel prices. Using profit-maximizationmodels for...

The U.S. Geological Survey has determined that irrigation in Arkansas’ Delta is unsustainable. This study examines how irrigation restrictions would affect county net returns to cropproduction. It also considers the effect of planting less water-intensive bioenergycrops—switchgrass and...

We examined four evolution paths of the biofuel sector using a partial equilibrium worldagricultural sector model in CARD that includes the new RFS in the 2007 EISA, a two-wayrelationship between fossil energy and biofuel markets, and a new trend toward corn oilextraction in ethanol plants. At...

The paper discusses the appropriate functional form and estimation technique for a wildlife production function on the farm level. A random effect model was developed to capture the relationship between wildlife output, management practices, natural conditions and non-observed factors that cause...

Reduction in coffee consumption has required from coffee organizations the development ofmarketing techniques so as to creating value to their product as well as reaching consumer’s satisfaction. Thiswork aimed at identifying questions on coffee consumers’ desires, perceptions, preferences...

A positive mathematical programming model was constructed in this study to assess theeffect of three water pricing scenarios on Teboulba’s agricultural production systems.The effects of these scenarios were estimated for three groups of farmers from three irrigated districts. Results show that...
