This is a really impressive talk! Focuses absolutely on the essential arguments and insights. And - depressingly rare for an economist - Andrew has really crafted this presentation. Thanks so much Taylor for this video series.

[@mystickarthikeyan]

Thank you very very very very much. Can't explain with words how useful this has been to me.

[@majsketchup]

You're saving my life right now. I've been stuck with my masters thesis and I couldn't find any good explanations in pervious literature on how this actually works in practically. Thank you so much for explaining this in a way that is comprehensible to mere mortals. Thanks, Taylor and thanks Andrew for coming up clutch.

[@AkashIssar]

Love the start of the video with Dr. Goodman-Bacon's start-up of this paper. :D Thanks Taylor :)

[@CJLee-jd2lh]

Thank you very much for sharing this. Andrew was a GREAT presenter, but also the questions at the end were really good, too. I've learend alot!

[@felixerpunkt1880]

great intuitive explanation. Thank you.

[@coolsteven2]

This was so well explained! Thank you for sharing.

[@ankitaghosh2574]

Thanks a ton for sharing this video series on developments in diff-in-diff. Treasure trove!!!

[@oldghaz]

Thank you for posting this. I wasn't able to attend for some reason, glad that I could catch up.

Hi professor how can I get data set to check for stata ?

[@BenOgorek]

Can anyone confirm that the "Partial out fixed effects" step at 12:17 only works when you've observed data for every unit at every time point (i.e., fully balanced)?

[@figowang8953]

I encountered this problem as well. The code "bacondecomp" in stata seems to only work for a strongly balanced dataset.

31:50 Why are states that switched before the data started having a high weight, and not a low weight? Also, it is bad to use already treated states as controls, right? So it would be a bad idea to include these states.

[@dr.kingschultz]

where are the R code videos?

[@c.comploj3775]

why do you monetize these videos where it is other people talking?

[@taylorwright3880]

The videos are not monetized.

@@taylorwright3880 Hmm, but there are ads. Maybe it is Google.
