In this study, we estimate production costs and elasticities of factor substitution for Zimbabwean smallholders, using a dual (cost function) approach with detailed data on prices paid and received by each of 65 farms across six survey sites over two years. We find that 95% of observed farm...

This study integrates biophysical simulation data with a farm household model of intertemporal optimization, to investigate changing crop-livestock management practices in the Sudano-Guinean zone of Mali. Over a 15-yr time horizon we find that free grazing on the commons remains more attractive...

This study investigates non-parametrically the optimizing behavior of a sample of 289 Kansas farms under profit-maximization and cost-minimization hypotheses. The study uses both deterministic and stochastic non-parametric tests. The deterministic results do not support strict adherence to...

This study's objectives were to determine factors influencing smallholder farmers' adoption of a stall-feeding management system for improved dairy cattle in semiarid Tanzania and other related technology packages. Heckman's two-stage procedure was used to determine factors influencing...
