In their books Freakonomics and SuperFreakonomics, Steven D. Levitt and Stephen J. Dubner use the tools of economics to explore real-world behavior. They tell stories about cheating schoolteachers, self-dealing real-estate agents, and crack-selling mama’s boys. WNYC is now bringing those Freakonomics stories — and plenty of new ones — to the radio, with Dubner as host. Just like the books, Freakonomics Radio explores “the hidden side of everything.” It tells you things you always thought you knew but didn’t, and things you never thought you wanted to know, but do.
