Contributor(s): Professor Sendhil Mullainathan | Why does poverty persist? Why do successful people get things done at the last minute? A single psychology--the psychology of scarcity--connects these seemingly unconnected questions. The research in our book shows how scarcity creates its own mindset. Understanding this mindset sheds light on our personal problems as well as the broader social problem of poverty and what we can do about it.
