He is clearly pro-union (which is fine), and his research to debunk Chetty et al. clearly play into the unions’ preference which is the status quo, do not distinguish superstar teachers from lousy teachers–all are equal.

I always have more trouble buying results that are aligned with the author’s personal views. But this is the norm in economics, I’m afraid. Part of it is surely that authors are drawn to study questions that mean a lot to them, personally.
