In this ebook on 'Healthcare for the Bottom of the Pyramid' (BOP) there are four insightful research chapters related to different aspects of healthcare management at the BOP. Two chapters are based on BOP consumers in India, one on BOP in Mexico, and the fourth on a social enterprise in Argentina. The four chapters complement each other very well and form a comprehensive package on healthcare delivery and policy making for poor healthcare consumers in developing and under-developed markets around the world. We hope the ebook would be of value to policymakers, healthcare marketers, as well as those involved in social marketing.
