Technology and farm performance: paths of productive efficiencies over time
研究了农民在采用新技术后，如何通过自身学习逐步调整农场绩效，发现仅靠经验学习会使技术潜力释放缓慢，基于印度数据的检验显示初期效率低且差异大，随时间推移平均效率上升。
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.
