The (fiscal) dividend of infrastructure: Roads and revenues in Rwanda
研究显示卢旺达道路升级显著提升当地税收，主要源于企业进入和土地增值，五年内地方收入翻倍以上。
This paper shows that infrastructure investments enhance local tax outcomes. Drawing on a novel dataset combining information on the location and timing of all road upgrades in Rwanda with 12 years of administrative tax and census records, we estimate large and significant increases in tax revenues in municipalities near upgraded roads. These effects are driven by firm entry as well as land value appreciation, captured through taxes on rental income at the local level. Finally, we show that while the additional revenues do not fully recover the central government’s initial investment, local municipalities’ revenues more than double within five years following the upgrades.
