Games in Economic Development examines the roots of poverty and prosperity through the lens of elementary game theory, illustrating how patterns of human interaction can lead to vicious cycles of poverty as well as virtuous cycles of prosperity. The book shows how both social norms and carefully designed institutions can help shape the "rules of the game," making better outcomes in a game possible for everyone involved. The book is entertaining to read, intended for a broad audience, and can be accessed with little background in development economics or game theory. Its chapters explore games in natural resource use; education; coping with risk; borrowing and lending; technology adoption; governance and corruption; civil conflict; international trade; and the importance of networks, religion, and identity, illustrating concepts with numerous anecdotes from recent world events. An appendix explaining basic ideas in game theory used in the book is provided for interested readers.
