The complex dynamics of smallholder technology adoption: the case of SRI in Madagascar
研究了马达加斯加小农户在金融市场和土地市场不完善环境下,对高产低外部投入水稻技术的采纳、扩大和放弃决策,发现季节性流动性约束阻碍贫困农户采纳,而学习效应(来自推广人员和其他农户)显著影响决策。
Abstract This article explores the dynamics of smallholder technology adoption, with particular reference to a high‐yielding, low external input rice production method in Madagascar. We present a simple model of technology adoption by farm households in an environment of incomplete financial and land markets. We then use a probit model and symmetrically censored least squares estimation of a dynamic tobit model to analyze the decisions to adopt, expand, and disadopt the method. We find that seasonal liquidity constraints discourage adoption by poorer farmers. Learning effects—both from extension agents and from other farmers—exert significant influence over adoption decisions.
