Evaluating Transport Infrastructure Projects in Low Data Environments: An Application to Nigeria
提出一种在数据受限环境下评估交通基础设施项目的方法,以尼日利亚为例,估算运输成本、道路改善对经济活动的影响,并模拟投资优先级排序。
Transport infrastructure consumes a large fraction of the development assistance envelope. Yet procedures for evaluating transport infrastructure projects are typically ad-hoc. This paper proposes an approach to assess the differential impacts of alternative investment proposals in data constrained environments where conducting reliable impact analyses is difficult. We first demonstrate a technique for estimating the cost of transporting products to markets. We then estimate the impact of improving the road network on economic activity. Finally, we perform simulations to demonstrate a methodology for prioritising alternative investments. The analysis demonstrates a pragmatic, though rigorous, approach for assessing transport infrastructure benefits.
