Season 7, Episode 21

Economists have a hard time explaining why productivity growth has been shrinking. This week on Freakonomics Radio, Stephen J. Dubner examines one theory: that true innovation has gotten much harder – and much more expensive. So what should we do next?

Also, Freakonomics co-author Steve Levitt answers your questions about highway-merging, crime, real-estate agents, and being too smart for your own good.

To find out more, check out the podcasts from which this hour was drawn: “Are We Running Out of Ideas,” “How Can I Do the Most Social Good With $100? And Other FREAK-quently Asked Questions,” and “Can You Be Too Smart for Your Own Good? And Other FREAK-quently Asked Questions.”
