The effect of information sources on technology adoption and modification decisions
研究贝宁南部农民对改良玉米储存技术的采纳与改进决策，发现通过推广人员和其他农民获取信息的两个群体在决策上存在差异。
Abstract This article focuses on adoption and modification decisions on improved maize storage technologies in southern Benin. Modification implies changing a technology to adapt to farmers' circumstances. A sample selection framework is used to account for selectivity bias as some farmers were not aware of the new technologies. Using this framework, the study investigates the effect of alternative information sources on adoption and modification decisions. Farmers are either informed by extension agents or by other farmers. The empirical results show that there are differences in adoption and modification decisions between these two groups.
