Book excerpt: Ever since demonetization, Dr. Fr. John P J has been thinking about publishing a book. He tossed the idea to us about what it could be and how we could go for really formalizing it. It just seemed like a neat idea, and gave us a ton of latitude to take things in our own way and focused heavily on the conceptualization of the entire process that could provide useful information about the impact of Demonetization to a broad audience.
