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...

A programming model is used to assess the welfare effects of regional and practice specifications contained in New York State's Draft Conservation Reserve Enhancement Program (CREP) proposal. Net social benefits are nearly 75% lower than options that explicitly account for opportunity costs of...

In Afghanistan, where 80% of the population is rural, irrigated agriculture is important for satisfying subsistence needs. While most of the irrigated agriculture is fed by diversion canal systems which tap surface flows, legal and physical water infrastructure in the region is generally poor. A...

This study makes use of linear programming methodology to design a minimum cost diet for the Central Ugandan region. We used a set of constraints on recommended levels of daily nutrient intake, recommended proportions of groups of foods, as well as preferences and food availability in Central...

This study extends and refines a previous model and provides estimates of the economic value of water shortages from shortfalls in Mexican deliveries to the U.S. In the process, we identify and evaluate a range of crop choices, appropriate irrigation technology use, water source substitution,...

When the lignocellulosic biofuels industry reaches maturity and many types of biomass sources become economically viable, management of multiple feedstock supplies – that vary in their yields, density (tons per unit area), harvest window, storage and seasonal costs, storage losses, transport...
