《JDE》| 农村道路基础设施和农业生产:来自印度的证据

摘要/关键词

摘要：

世界上有很大一部分贫困人口生活在偏远地区，这些地区的高成本和有限的交通限制了经济活动。本文分析了在一个大型农村道路建设计划下基础设施的改善对农业生产决策的影响。能够使用规划道路的偏远家庭可以实现作物品种多样化，采用现代农业技术，并增加劳动力的雇用。目前的证据表明，规划道路可以整合农村劳动力市场，提高了农业工人的流动性，从而使劳动密集型生产实践得以采用。这些发现强调了发展中国家偏远地区“最后一英里”连接的重要性。

Abstract：

We use a two-stage experiment to study how a short-term subsidy for a new product affects uptake, usage, and future demand for the same product (a new solar lamp). We use an auction design to gauge willingness-to-pay, and randomly vary the strike price across villages to create random variation in purchase prices and uptake across villages. Our main results are that subsidies do not adversely affect subsequent product use, but stimulate uptake. If subsidies depress future willingness-to-pay, then this effect is outweighed by additional learning about the benefits of the new product. The net effect is that short-term subsidies increase future willingness-to-pay. However; prices play an important allocative role, and lowering prices via subsidies encourages uptake by households with low use intensity. We do not find any evidence supporting social learning and anchoring beyond the initial sample of beneficiaries.
