We construct a model of technology adoption with agents differing on two dimensions: their cognitive ability and their receptiveness to advice. While cognitive ability unambiguously speeds adoption, receptiveness to advice may speed adoption for individuals with low cognitive ability, but slow adoption for individuals with high cognitive ability. We conduct economic experiments measuring US farmers' cognitive ability and receptiveness to advice and examine how these characteristics impact their speed of adoption of genetically modified (GM) corn seeds. The empirical analysis shows that early adopters are those who are both quite able cognitively and not receptive to advice.
我们构建了一个技术采用模型，其中的主体在两个维度上存在差异：他们的认知能力和对建议的接受程度。虽然认知能力无疑会加速采用过程，但对建议的接受程度对于认知能力低的个体可能会加速采用，而对于认知能力高的个体则可能会减缓采用。我们进行了经济实验，测量美国农民的认知能力和对建议的接受程度，并研究这些特征如何影响他们采用转基因玉米种子的速度。实证分析表明，早期采用者是那些认知能力相当强且不接受建议的人。
