We study the production efficiency of teff in Ethiopia. Using a large cross-section of teff plots, we find that teff output could be increased by approximately 25 percent with the available inputs and technology through investments directed to improved gender-sensitive extension service and infrastructure development. The magnitude of technical inefficiency is robust to alternative functional form and various variable specifications. Community discussion groups and distance to the nearest agricultural co-operative are further shown to have a significant effect on technical efficiency. We conclude the paper by discussing the potential policy implications of our findings.
