I was wondering if anyone had any particular recommendations on materials to read or mess around with. Obviously it’s a fast-moving field, but anything you feel is a good source for new information, new tools, or even a great intro to parts of the field people may not have had their hands on would be much appreciated.
In my case, I recall enjoying much of “Mostly Harmless Econometrics” as part of the readings I ended up doing on causal inference. Causal inference is hard to do, typically requires very careful experimental design, and tends to use a lot of the “unglamorous” methods, but when you need those techniques, you really need them.
