Labour, profitability and gender impacts of adopting row planting in Ethiopia
通过随机对照试验，发现埃塞俄比亚的条播技术虽增加劳动投入，但未提高产量，导致劳动生产率下降且无显著盈利效果，解释了推广受限的原因。
Improved technologies are increasingly promoted to farmers in sub-Saharan Africa to address low agricultural productivity. There is, however, a lack of evidence on how adoption affects farmers' labour use, gender roles and profitability. This paper analyses the farm level impacts of the recently introduced row planting technology in teff production in Ethiopia. Using a randomised controlled trial, we show that row planting significantly increases the total labour requirement and allocation but not teff yields, resulting in a substantial drop in labour productivity. There is no significant profitability effect at the farm level, seemingly explaining the limited success in upscaling the programme.
