The Golden Quadrilateral Highway Project and Urban/Rural Manufacturing in India
This study investigates the impact of the Golden Quadrilateral highway project on the urban and rural growth of Indian manufacturing. The Golden Quadrilateral project upgraded the quality and width of 5,846 km of roads in India. The study uses a difference-in-difference estimation strategy to compare non-nodal districts based on their distance from the highway system. For the organized portion of the manufacturing sector, the Golden Quadrilateral project led to improvements in both urban and rural areas of non-nodal districts located 0-10 km from the Golden Quadrilateral.
