ABSTRACT Using plot-level data from Ethiopia, this study aims to examine the determinants and impact of alternative teff production technologies on the productivity and profitability of smallholder teff producers. The study employed a multinomial endogenous switching regression (MESR) model that accounts for selection bias due to observable and unobservable factors. The authors’ results show that technology adoption has a positive association with education, farm size, extension visits, community meetings and asset ownership. On the contrary, distance to input and output markets have a negative and significant effect on the adoption of alternative teff production technologies. The MESR model results reveal that, while full technology adoption is the most productive and profitable option, adopting any of the alternative technologies also substantially improves the productivity and profitability of smallholder teff producers. The results also suggest that row-planting technology has a positive impact on the productivity and profitability of smallholder teff producers only when it is adopted with improved seed technology.

替代画眉草生产技术的采用和事后影响：来自埃塞俄比亚的微观证据

摘要 本研究使用埃塞俄比亚的地块级数据，旨在研究替代画眉草生产技术对小规模画眉草生产者生产力和盈利能力的决定因素和影响。该研究采用多项内生转换回归 (MESR) 模型，该模型解释了由于可观察和不可观察因素导致的选择偏差。作者的结果表明，技术采用与教育、农场规模、推广访问、社区会议和资产所有权呈正相关。相反，与输入和输出市场的距离对采用替代画眉草生产技术具有负面和显着的影响。MESR 模型结果表明，虽然全面采用技术是最高效和最有利可图的选择，采用任何替代技术也大大提高了小规模画眉草生产者的生产力和盈利能力。结果还表明，只有在采用改进的种子技术时，行种植技术才能对小规模画眉草生产者的生产力和盈利能力产生积极影响。
