To analyze U.S. consumers' brand choices for cheese purchases, we derive a set of discrete-choice models from dynamic utility maximization. ACNielsen Homescan Survey data on U.S. households is used to estimate a dynamic probit model for each of the top brands for cheddar, shredded, and sliced...

As one of the measures to smooth income, this paper focuses on the diversification of labor allocation across activities. A key feature of this paper is that it pays particular attention to differences in the covariance between weather risk and agricultural wages and between weather risk and...

During the 2004 food crisis in Niger, the weakness of the main production system, millet, to produce enough food to sustain short term crises, has been revealed. Questions arise how the Nigerian smallholder systems can be assisted by research and development policies to intensify production and...

This study evaluates the welfare implications of tariff reforms in the cereals sector of the SADC region. Applying the global simulation model (GSIM), a multi-country partial equilibrium model, to the cereals industries of thirteen SADC countries, the study computes price and welfare effects of...
