Econometrics is so complicated. It's not like a example i use as n where's john glen going to come down in this spacecraft if we change angle, and he's either there or he isn't. Maybe i'm wrong, but the idea that in let's take your of the work we've been talking about from the facebook data, you moved this person from a less connected community to a more connected community. On average, there going to gain 20 % you can't verify it. Do you feel like we're getting closer to the truthd and how comfident should we be it this are all I think it's a healthy skepticism.

Economist Raj Chetty of Harvard University talks about his work on economic mobility with EconTalk host Russ Roberts. The focus is on Chetty's recent co-authored study in Nature where he finds that poor people in America who are only connected to other poor people do dramatically worse financially than poor people who are connected to a wider array of economic classes. The discussion includes the policy implications of this result as well as a discussion of Chetty's earlier work on the American Dream and the challenge of Americans born in recent decades to do better financially than their parents.
