Efosa Ojomo and Karen Dillon, co-authors with Clayton Christensen on The Prosperity Paradox: How Innovation Can Lift Nations Out of Poverty, discuss the story behind their newly-released book, what it's like to collaborate with Clay, and the substance of The Prosperity Paradox, in which they address the question, "Where does true and lasting prosperity come from?" With an eye towards low income countries, the conversation touches on different types of innovation, non-consumption, push versus pull strategies, a new way of thinking about infrastructure, business model development, and their framework for economic growth based on market-creation innovation and entrepreneurship.
