The Impact of Agricultural Extension and Roads on Poverty and Consumption Growth in Fifteen Ethiopian Villages
研究埃塞俄比亚农村道路改善和农业推广服务对消费增长和贫困率的影响，发现至少一次推广访问使贫困率降低9.8个百分点，消费增长提高7.1个百分点；全天候道路使贫困率降低6.9个百分点，消费增长提高16.3个百分点。
Abstract This article investigates whether public investments that led to improvements in road quality and increased access to agricultural extension services led to faster consumption growth and lower rates of poverty in rural Ethiopia. Estimating an Instrumental Variables model using Generalized Methods of Moments and controlling for household fixed effects, we find evidence of positive impacts with meaningful magnitudes. Receiving at least one extension visit reduces headcount poverty by 9.8 percentage points and increases consumption growth by 7.1 percentage points. Access to all‐weather roads reduces poverty by 6.9 percentage points and increases consumption growth by 16.3 percentage points. These results are robust to changes in model specification and estimation methods.
