Brazil uses taxes, subsidies, and blending mandates as policy instruments to manage its transportation fuel markets. Despite all the market stabilization efforts, the fuels sector has been very dynamic in recent years. In response to ethanol supply fluctuations, the ethanol blending rate is...

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...

Mathematical programming-based systems analysis is used to examine the consequences of alternative operation configuration for the agricultural operations within the Texas Department of Criminal Justice. Continuation versus elimination of the total operation as well as individual operating...

Policies to mitigate greenhouse gas emissions are likely to increase energy prices. Higher energy prices raise farmer costs for diesel and other fuels, irrigation water, farm chemicals, and grain drying. Simultaneously, renewable energy options become more attractive to agricultural producers....

Climate change may affect the use of pesticides and their associated environmental and human health impacts. This study employs and modifies a partial equilibrium model of the US agricultural sector to examine the effects of alternative regulations of the pesticide and greenhouse gas emission...

All agricultural sector models must deal with aggregation and calibration somehow. The aggregation problem involves treating a group of producers as if they all responded in the same way as a single representative unit. The calibration problem concerns making a model reproduce as closely as...

Pesticides used in agricultural production affect environmental quality and human health. These external costs can amplify due to climate change because pest pressure and optimal pesticide application rates vary with weather and climate conditions. This study uses mathematical programming to...
