Economic Benefits of Rural Feeder Roads: Evidence from Ethiopia
研究估计了埃塞俄比亚农村家庭对支线道路的支付意愿，通过比较不同偏远程度家庭的经济行为，发现碎石路的内部收益率在12%到35%之间，表明即使在不利条件下，农村支线道路也可能有较高回报。
We estimate households’ willingness-to-pay for rural feeder roads in Ethiopia. Using purposefully collected data, we compare the economic behaviour of households by remoteness to estimate the benefits of access to feeder roads. Although we cannot definitively assert a causal relationship, we cautiously estimate that gravel roads have internal rates of return of 12–35 per cent. These results suggest that rural feeder roads may have relatively high rates of return even in unfavourable settings where (a) small-scale farmers have low levels of marketed agricultural surplus, (b) non-farm earning opportunities are negligible, and (c) motorised transport services are not guaranteed.
