Global poverty is one of the world’s most vexing problems. For decades, we’ve assumed smart, well-intentioned people will eventually be able to change the economic trajectory of poor countries. From education to healthcare, infrastructure to eradicating corruption, too many solutions rely on trial and error. Essentially, the plan is often to identify areas that need help, flood them with resources, and hope to see change over time. But hope is not an effective strategy.

Clayton M. Christensen and his co-authors reveal a paradox at the heart of our approach to solving poverty. While noble, our current solutions are not producing consistent results, and in some cases, have exacerbated the problem. At least twenty countries that have received billions of dollars’ worth of aid are poorer now.

Applying the rigorous and theory-driven analysis he is known for, Christensen suggests a better way. The right kind of innovation not only builds companies—but also builds countries. The Prosperity Paradox identifies the limits of common economic development models, which tend to be top-down efforts, and offers a new framework for economic growth based on entrepreneurship and market-creating innovation. Christensen, Ojomo, and Dillon use successful examples from America’s own economic development, including Ford, Eastman Kodak, and Singer Sewing Machines, and shows how similar models have worked in other regions such as Japan, South Korea, Nigeria, Rwanda, India, Argentina, and Mexico.
