Some struggle with medical issues - like insomnia - that make sleep hard. But for many of us, the quantity and quality of sleep come down to a matter of choice. Still, only a few enterprising economists have looked closely at this, and generally, those have assumed that we choose our hours of sleep optimally. -Sendhil Mullainathan Medical
Economists specialize in pointing out unpleasant trade-offs - a skill that is on full display in the health care debate. We want patients to receive the best care available. We also want consumers to pay less. And we don't want to bankrupt the government or private insurers. Something must give. -Sendhil Mullainathan Health
