Andrew Goodman-Bacon “Difference-in-Differences with Variation in Treatment Timing”

[@danbrown3848]

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.

I had spent so much time on reading the GB paper and yet could not understand it. Now after watching this video for one hour, I understood what this paper was all about. Thank you sooooo much!😀😀😀

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

Notation and discussion at 4:33 is not ideal. It´s confusing the parameter beta with it´s estimator (maybe estimate) "beta hat".

[@c.comploj3775]

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.

[@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.

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

[@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.

[@c.comploj3775]

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