Major issues and challenges encountered in modeling and analyzing agricultural and trade policy reforms are reviewed. We focus on the modeling approach and pay special attention to the type and scope of the models, the calibration of a realistic baseline scenario, the representation of the...

We analyze the impact of trade liberalization, removal of production subsidies, and elimination of consumption distortions in world sugar markets using a partial-equilibrium international sugar model calibrated on 2002 market data and current policies. The removal of trade distortions alone...

Major changes in the use of US sweeteners have occurred since 1970, in both the amount and composition. Increased consumption of caloric sweeteners, especially in beverages, has been linked to excess energy intake and lower-quality diets. We examine how US farm policies (specifically...

We introduce a world fertilizers model that is capable of producing fertilizer demand projections by crop, by country, by macronutrients, and by year. For each crop, the most relevant countries in terms of production, consumption, or trade are explicitly modeled. The remaining countries are...

We investigate factors affecting the duration of eating and food preparation among adults in single decision-maker households. Eating time is differentiated into primary and secondary eating time and further differentiated by location: at home vs. away from home. We construct a simple...

Past studies that examine the impact of ethanol mandates on fuel prices make the assumption that ethanol and gasoline are perfect substitutes because they are both sources of energy in transportation fuels. These studies, however, have been of limited use in informing current policy debates...

We compute the fertilizer use in corn, cotton, soybeans, and rapeseed in the period from 1990 to 2010 for a set of selected countries. In each case, we present the consumption of nitrogen, phosphate, and potash by crop and by year, reporting both the fertilizer application rates (in kilograms...

This paper models producers' interdependent incentives to participate in a voluntary livestock disease control program. Under strategic complementarity among participation decisions, after a slow start momentum can build such that market premium for participation and participation rate increase...
