Peer effects and the choice of adaptation strategies
利用埃塞俄比亚尼罗河流域农户的三年面板数据，研究发现同伴选择显著影响气候变化适应策略的采用，同伴使用某策略的比例每提高10个百分点，农户采用该策略的可能性增加7%至14%。
Abstract This paper analyzes the impact of peer choices on the decision to adapt to climate change in rural Ethiopia. Two IVs are employed (peer‐of‐peer choices and peer‐of‐peer information sources) in order to tackle the issue of endogeneity. Through the use of a 3‐year panel of farmers in the Nile Basin region, we find that peer choices positively affect the uptake of different adaptation strategies. A 10 percentage point increase in the share of peers using a specific strategy translates to an increase in the likelihood of adaptation between approximately 7% and 14%. This emphasizes the importance of social networks to achieve adaptation to climate change in sub‐Saharan Africa.
