Technology and farm performance: paths of productive efficiencies over time
研究了农民学习新技术时农场绩效的调整过程，发现仅靠自身经验学习，农民难以快速实现新技术的全部技术潜力。基于印度数据验证了初期效率低且差异大、随时间平均效率上升的假设。
Abstract The focus of this paper is the process of adjustment of farm performance to disequilibrium with new technology over time, which has been a subject of speculation till now. It shows that, left to learn from their own experience, farmers will be slow to realise the full technical potential of a new technology. Drawing on theories of intra‐firm diffusion, the hypotheses tested in this paper using data from India are: (1) initial overall farm performances are characterised by modest and widely varying technical and allocative efficiencies, and (2) over time, average efficiencies rise.
