One of the distinguished speakers at the NDTV world summit, Nobel laureate Paul Romer interacted with various government officials today to understand how the Narendra Modi Government is not just using technology to implement its welfare schemes but also to propel its growth story. The globally reputed economist was specifically curious about the popularity of UPI in the country, its inclusive nature and penetration, and the use of tech in financial inclusion programmes such as Jan Dhan yojna. Paul Romer won a Nobel Prize in economics in 2018 for his upbeat theory of growth, which shined a light on how ideas, rather than mere things, lead to economic expansion and human progress.
