A few weeks back, I posted on a WB report on doing business in South Asia. Someone had commented on the post asking for more information on bottom-of-the-pyramid markets. The World Bank has a new publication out estimating that the size of the bottom-of-the-pyramid market is around $5 trillion. It’s an interesting report, looking  at various sectors, including health, ICT, water, energy, and transportation among other. Read the whole report here.
