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 of all these problems is that they're all about scarcity. We've all struggled with packing a suitcase with too many items and not enough time to do it. In Scarcity, two intellectual adventurers show us that this simple idea explains the most fundamental problems in all walks of life. 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.Sendhil Mullainathan is a Professor of Economics at Harvard, and a recipient of a MacArthur Foundation genius grant.
