I'm on the #EconJobMarket! I study how policies and childhood environments shape outcomes of low-income & vulnerable kids.
In my JMP, I study the effects of allowing youth who would have aged out of foster care at 18 to stay until 21—offering support their peers not in foster care get from parents.

Chicago Pope, notorious for asking tough questions in seminars.
The Prime Minister faced yet another setback this week as the ongoing scandal over two-way fixed effects produced two more estimators for Canadians to learn. ‘You’re telling me these regressions produced negative weights and the Liberals knew nothing?!” the Conservative Party leader tweeted Sunday
I need the “Campaign in prose. Govern in econometrics.” t-shirt.

does there exist any helpful document out there that is like "a checklist of things every experienced researcher checks their tables and figures for to see if something is off?" I'm thinking of items such as "do N's change across regression model specifications and if so why?"

Random Stata tip, mostly for future me. If you want to add /// to the end of many lines at once (this comes up for me when copying SQL queries from other code editors or code that uses a ; delimiter), you can find & replace, check the regular expression option do:
find:

replace:
" ///\0"
