JUE insight: Infrastructure and Finance: Evidence from India’s GQ highway network

Abstract

We use data from Reserve Bank of India to study the impact of India’s Golden Quadrilateral (GQ) highway project on finance-dependent activity. Loan volumes increase by 20%–30% in districts along GQ and are stronger in industries more dependent upon external finance. Loan growth begins with increases in average branch size and in places with more pre-GQ loan activity. New branch openings come later, consistent with short-run adjustment costs to expanding branch networks. These patterns are not evident in placebo tests using delayed investments in NS-EW highways. Results suggest the depth of initial financial infrastructure shapes how infrastructure investments impact localities.
