Rama was the keynote speaker at CPRsouth2. She was fascinating. A person who looks at the bottom of pyramid without a special emphasis on ICTs; relying on data, but applying real thinking to the data rather than just parrot the data. End result was that I bought her book and read it end-to-end (something I rarely do these days). She mentions in several places that the SEC D&E consumers are willing to spend more money than expected on education, health and transport.
