Access to Markets and the Benefits of Rural Roads
利用尼泊尔数据，通过农田价值与市场距离的关系估算农村道路项目的家庭收益，发现道路能带来可观收益且多数流向贫困家庭，但不足以显著降低收入不平等。
Roads play a central role in rural development, yet little is known about the size and distribution of benefits from such investments. This paper develops a method for estimating household-level benefits from road projects using the relationship between the value of farmland and its distance to agricultural markets. The empirical analysis, using data from Nepal, suggests that providing extensive road access to markets would confer substantial benefits on average, much of these going to poor households. However, the benefits would not be large enough or targeted efficiently enough to appreciably reduce income inequality in the population.
