Tyler Cowan interview of Raj Chetty

Here. An excerpt:
"COWEN: If I’m trying to model the Raj Chetty production function and I described it as such, it’s a multiplicative model, so there is getting the data, but that’s not the key point.

CHETTY: That’s not the key point.

COWEN: There’s then some conceptual advance that allows you to see the data can test something that other people hadn’t seen, and then there are numerous stages of execution, and then there’s also recruiting and managing the team. There’s a whole bunch of different steps, and you’re trying to do well at each of them and very few other people can do well at each and every one, and maybe that’s the way to think about your moat. Is that fair to say?

CHETTY: That is our strategy. I think the other thing that’s extremely important is, we spend a lot of time on trying to achieve clarity. There are ways to write papers in economics that are more accessible to the public and thereby have greater impact, and there are ways to write papers that are more technically oriented and narrow the set of readers."

P.S. I thought it was me who gave Raj his first computer. He seems to have forgotten. From an interview with his father, it was a Sinclair and he was three at that time.
