For centuries, cities have been the beacon for economic prosperity. Drawn by the promise of economic, social and political opportunity, more than half the world’s population live in cities today. In India alone, 90 million people migrated from farms to cities in the last decade. The prospect of higher wages and better living standards is expected to draw 250 million more by 2030.
Urban success is based on economies of agglomeration -- where density increases the ease of moving goods, people, and ideas – increasing productivity. However, compared to other emerging economies, Indian cities do not appear to have captured gains from economic concentration. While the service sector and high-tech manufacturing have benefitted from agglomeration more than other sectors, overall urban productivity has not kept pace with India’s economic growth. In fact, the urban share of national employment has not increased between 1993 and 2006.
Are the costs of density overwhelming the benefits from clustering?
