This document summarizes a technical report on the impact of India's 2016 demonetization. It provides background on the demonetization, noting that ₹500 and ₹1000 notes made up 86% of cash in circulation. The author's objectives are to study past demonetizations, understand their outcomes, and analyze demonetization's effects and costs/benefits in India. Several studies are reviewed that model demonetization's impacts on GDP, markets, and inflation. Most countries that demonetized struggled with growth declines, but a few like the US and UK recovered after. The success of India's effort depends on behavioral factors and appropriate policy responses.
