In this paper, we simulate the Brazilian agriculture and transportation fuel sectors using a price endogenous mathematical programming model to analyze the impacts of recent changes in fuel policies and strong demand in world sugar markets on producers’ supply responses, consumers’ driving...

An integrated watershed management framework that combines detailed spatial biophysical attributes of land with a hydrologic model and an economic model is developed to study the cost-effective enrollment of land in the Conservation Reserve Enhancement Program (CREP). Compared with previous...

This paper develops a dynamic micro-economic land use model that maximizes social welfare and internalizes externality from greenhouse gas emissions to obtain the optimal land use allocation for traditional row crops and bioenergy crops (corn stover, miscanthus and switchgrass), the mix of...

Biofuels have been promoted to achieve energy security and as a solution to mitigating climate change. This research presents a framework to examine the extent to which biofuel mandates and subsidies reduce gasoline consumption and their implications for the food and fuel prices. A dynamic,...

With the increasing research interests in biofuels, global implications of biofuels production have been generally examined either in a partial equilibrium (PE) or general equilibrium (GE) frameworks. Though both of these approaches have unique strengths, they also suffer from many limitations...

Irrigation, under conditions where water has a high opportunity cost, could be interruptible with water use, only occurring when water is plentiful. Pacific Northwest case studies indicate interruption can substantially lessen the opportunity cost of new irrigation developments, although not...
