In November 2016, India’s prime minister announced that all bills over 500 rupees were demonetized in an attempt to fight corruption. As a result, 86% of India’s currency disappeared overnight! Harvard’s Gabriel Chodorow-Reich and his coauthors took advantage of this sudden natural experiment to examine the role of money in modern economies.
Different districts of India took different approaches to demonetization-some replaced the currency quickly while others took longer. But studying the various effects was difficult because of a lack of reliable data.
By using employment surveys-simply measuring whether people are working-and satellite-based night light activity-measuring how much light is being generated in a particular location-Chodorow-Reich and his team were able to compare economic outcomes across regions with a high degree of accuracy.
This video is based on the following paper: Cash and the Economy: Evidence from India's Demonetization by Gabriel Chodorow-Reich, Gita Gopinath, Prachi Mishra, and Abhinav Naraynan. scholar.harvard.edu/chodorow-...
