Husbands’ and wives’ risk preferences and improved maize adoption in Tanzania
研究利用坦桑尼亚夫妇的实验风险偏好数据，发现妻子风险厌恶和丈夫损失厌恶与改良玉米品种采用负相关，而小概率高估倾向的影响因性别而异，提示技术推广应同时针对男女。
Abstract Research on technology adoption typically assumes that the preferences of a single individual—the household head—determine household‐level decisions. This study uses experimentally derived prospect theory‐based risk preferences from couples in Tanzania to test whether men's and women's risk preferences, which often diverge, influence the adoption of improved maize varieties. We find that women's risk aversion and men's loss aversion are negatively correlated with improved variety use. The tendency of men to overweight small probabilities is negatively associated with adoption, whereas the tendency of women to do so is positively associated. These findings suggest that technology adoption research should look beyond the preferences of the household head, and that technology promoters should consider targeting both men and women in their education and dissemination efforts.
