In this provocative book based on cutting-edge research, Sendhil Mullainathan and Eldar Shafir show that scarcity creates a distinct psychology for everyone struggling to manage with less than they need.

Busy people fail to manage their time efficiently for the same reasons the poor and those maxed out on credit cards fail to manage their money. The dynamics of scarcity reveal why dieters find it hard to resist temptation, why students and busy executives mismanage their time, and why the same sugarcane farmers are smarter after harvest than before.

Once we start thinking in terms of scarcity, the problems of modern life come into sharper focus, and Scarcity reveals not only how it leads us astray but also how individuals and organizations can better manage scarcity for greater satisfaction and success.

Traditional public finance provides a powerful framework for policy analysis, but it relies on a model of human behavior that the new science of behavioral economics increasingly calls into question. In Policy and Choice economists William Congdon, Jeffrey Kling, and Sendhil Mullainathan argue that public finance not only can incorporate many lessons of behavioral economics but also can serve as a solid foundation from which to apply insights from psychology to questions of economic policy.

The authors revisit the core questions of public finance, armed with a richer perspective on human behavior. They do not merely apply findings from psychology to specific economic problems; instead, they explore how psychological factors actually reshape core concepts in public finance such as moral hazard, deadweight loss, and incentives.

Part one sets the stage for integrating behavioral economics into public finance by interpreting the evidence from psychology and developing a framework for applying it to questions in public finance. In part two, the authors apply that framework to specific topics in public finance, including social insurance, externalities and public goods, income support and redistribution, and taxation.

In doing so, the authors build a unified analytical approach that encompasses both traditional policy levers, such as taxes and subsidies, and more psychologically informed instruments. The net result of this innovative approach is a fully behavioral public finance, an integration of psychology and the economics of the public sector that is explicit, systematic, rigorous, and realistic.
