Sendhil Mullainathan, the 'most interesting young economist in the world', and Eldar Shafir, the 'most brilliant psychologist' of his generation, explain the hidden problem behind everything with Scarcity

Why can we never seem to keep on top of our workload, social diary or chores? Why does poverty persist around the world? Why do successful people do things at the last minute in a sudden rush of energy? Here, economist Sendhil Mullainathan and psychologist Eldar Shafir reveal that the hidden side behind all these problems is that they're all about scarcity. Using the new science of scarcity, they explain why obesity is rampant; why people find it difficult to sleep when most sleep deprived; and why the lonely find it so hard to make friends. Scarcity will change the way you think about both the little everyday tasks and the big issues of global urgency.

'Scarcity is a captivating book, overflowing with new ideas, fantastic stories, and simple suggestions that just might change the way you live' - Steven D. Levitt, coauthor of Freakonomics
