This paper measures the technical, allocative, and economic efficiencies of farmers within and outside the Extension Package Program (EPP) in high and low potential agro-ecological zones in eastern Ethiopia. Within-group farmer efficiencies are analyzed relative to respective technologies to...

This study employed a Tobit model to examine factors that influence the adoption and intensity of utilisation of improved maize varieties in the West Shoa Zone in the central highlands of Ethiopia. The estimated results indicate that level of education, household labour, farm size, extension...

This paper applied an extended total factor productivity analysis to compare the resource use efficiency of alternative cropping systems in eastern Ethiopia. The results indicated considerable variation in resource use efficiency among cropping systems. Intercropping of sorghum with pulses in...

The productive efficiencies of traditional and hybrid maize producers in eastern Ethiopia are derived using an efficiency decomposition technique that we extend to account for scale effects. The paper illustrates the sensitivity of the conventional approach to scale effects. The results revealed...
