This is Freakonomics Radio on Marketplace.

Here's the host of Marketplace, Kyra's Doll.

Time now for a little bit of Freakonomics Radio that moment in the broadcast every couple

of weeks where we talk to Steven Dubner, the co-author of the books and the blog of the

Dubner, welcome back.

Thank you, Ky.

I want to talk to you about this economic buzzword these days, innovation.

Oh, yeah.

Seven, I mean, that's amazing.

That's, at least, 93 something percent for men.

That's ridiculous.

Well, 92 something, but, you know, I know math is not your strong answer.

I'm a math guy.
