Identification, Part 4: Differences-in-differences / Natural Experiment

[@mikecheng6010]

Man this is one of the best explanations I see on this topic. My professors at UChicago just assumed people with no econometric background to be able to delve into harder topics without thorough explanations on the shallower ones. I really wish you can do a video or two on MLE/GMM/BLP etc..

[@ethanwaggoner9395]

HAHA I'm taking SSI, I am a Uchicago student myself. It's crazy that we literally go to the best economics school in the country and yet the best explanation I've heard on this topic is from someone on KZbin

Your explanation is really good..keep it up..it helps a lot.

[@julianduggan342]

Mapping the coefficients onto the chart that way is so useful -- thank you!

[@StephanieHughesDesign]

As an undergrad BA Econ. grad they never taught me Econometric D in D. This is stellar. Thanks Prof. Ashley.

[@alexhoward9031]

thank you so much! this was very helpful!

[@sun-riseshetty556]

Nice..

[@empiricistsacademy7181]

Nice intuitive and visual explanation of diff-in-diff. I noticed at 3:00 you say that main variable of interest is beta3. That should say parameter instead of variable since we don't observe beta3.

[@zhenghan5335]

To be honest, I think that is not the very standard DID estimation. But the logic behind the standard one is similar to this.

[@carterbrown2334]

this is helpful, thanks!

[@user-wr3tm2xl1t]

[@tsehayzeleke9743]

helo Ashley it was helpful thank you!!!!!!!!!!!!!!

[@nickgeary7919]

Thank you lots!

[@neerusingh5480]

Really very helpful. Can you also make one video on regression slops and what max or min value they must accept.or below some value shows that data is not consistent.

[@mocowang4971]

life saver!!! Thank you! Will you do some deeper videos for identification strategy?

[@iidtxbc]

Are they dummy variables with a value of 0 or 1 in the regression?

[@fungkiediharja8162]

very good video

[@ibrahimacoulibaly5199]

Although DiD may be useful to establish a causal effect, some of the DiD assumptions, such as the exclusion restriction is more controversial than independence assumption. The researcher should be more aware when use or explain DiD. Good Job!

[@kidannguse-vu1in]

How was doing in a SPSS?

[@yassminbachar3099]

if two slave trades are compared in relation to the current women participation in labor, would that be a natural experiment?

[@thomasbauer3742]

Hi Ashley, thank you for your videos. Really well done! I have two questions: 1) Does this also work if the slope changes as well (not only the intercept)? 2) More technical: How do you treat time here? If I am looking at monthly numbers from 09/2015 to 08/2017. Is 09.2015=1, 10/2015=2 etc? Thank you in advance!

[@umairghouri7122]

Thank you

[@alicew.1560]

Hey, great video, thanks a lot! I have a question: I have a treatment and a control group and at a specific date, there was a new legislation which affected the treatment group. So what time before and after do I have to chose? A year before/after, a month before/after or the day before/after the date of the new bill? Thanks!

[@stefyuthechosenone1458]

Jokes apart, your explanations are really appreciated and help a lot ! I mean a lot ! May we know you better like what is your background and the class you are teaching ? You can keep secret your phone number to the rest of the world. It will be our first secret ! P.S. : I am not joking at all when I was asking for your number by the way, all else are jokes !

[@eniolaolaniran656]

Thank you for your effort and good tutorials Please do you have an email? It will be good to discuss something with you. If you do not mind. Thank so much
