A number of economists, psychologists, and neuroscientists are using imaging studies to peek at the brain in action — trying to better understand why we make some of the choices we do.

Polaroid went from ubiquity to obsolescence as digital photography replaced the print. But as early as the 1960s, Polaroid had been doing research into digital imaging. Did mistaken assumptions keep the company from making the transition to the digital world?

Richard Thaler outlines how principles from behavioral economics can help policymakers — and managers — achieve better outcomes.
