Abstract

Abstract Transport corridors can generate both wider economic benefits (WEBs) and costs through their effects on diverse development outcomes. To advance understanding of how corridors could generate WEBs, this paper undertakes a quantitative review and meta‐analysis of the literature that estimates the impacts of large transport infrastructure projects. The analysis finds that characteristics of individual studies and the design of the transport infrastructure influence estimated benefits. It also shows that, on average, while corridor interventions tend to benefit economic welfare and equity, they often detrimentally impact the environment. To mitigate trade‐offs, policymakers can consider using complementary interventions.
