He was a BA in Psychology and a PhD in Public Policy.
How much math did David Autor have?

I had very little formal math or stats training and generally colleagues at my top 30 ask me for econometric advice. But I'll note that I did struggle with coursework during the first year of my Ph.D., i.e. retook and barely passed my quals.

More than enough and probably more than you. Publish as much seminal work as he has and then you can talk about his math chops. Tool.
Not trying diss him. Just curious.

Pretty sure I asked about Autor not you.

He probably had calculus and maybe linear algebra. That's all the prep you need for economic research tbh.
Is this actually true, assuming the research isn't pure theory?
You don’t need real analysis for pure theory either... just a good knowledge of calculus.

To be fair, they teach you all you need for economic research during the first two years of any econ phd program.

Including how to write proofs for economic theory.

There are always exceptions to every rule.
did harvard econ sequence while at Kennedy
Actually I was Harvard Econ and HKS students are not allowed to take the econ sequence.
I can confirm this. Harvard 2010a through 2010d is reserved for (and only for) econ, busecon, and peg students. Harvard College students are allowed to take it subject to the permission of the instructor. But no other phd student can take these 4 classes, along with certain other econ department graduate classes.
The econ department does offer a watereddown version of 2010a and 2010b, called 2020a and 2020b. This is a requirement for ppol phds.
