Thanks, Josh. Amazing work that certainly changed the social sciences.

[@donharris8846]

Thank you for this contribution. This will certainly positively impact Academia, but more importantly, real world policy in the future

Great work! Please upload more videos.

I didn’t understand the concept exactly but sounds revolutionary.

Amazing thanks!

I am so confused, enrollment in exam schools boosts scores. So even if their increased enrollment, means the number enrolled in charter schools suffer, ACT scores shouldn't fall... What am I missing?

[@gailiuspraninskas3211]

In the Chicago example, enrollment in exam schools does not boost scores -- see 13:21. At the enrollment cutoff, ACT Math scores fall. What follows is that exam schools attract better applicants (as measured by peer baseline scores), but they do not result in better ACT scores. Angrist goes on to argue that the mechanism behind this is a sort-of displacement effect out of charter schools, which actually do improve exam scores.

@@gailiuspraninskas3211 Plus, u also just demonstrated his presentation skills be sorely lacking. In fact, his not emphasizing exam schools r similar 2 public schools, smacks of a lack of courage. Since he clearly took time to denigrate the latter... Geeze, can't even trust a Nobel laureate these days!!

I didn’t quite understand why baseline math scores lose their importance in predicting qualification rates near the cutoff. I understand the example in the case of potential Nobel prize winners as just-winners and just-not-winners converge to become similar in a small bandwidth around cutoff. But 75th and 25th percentile baseline math scores remain far apart even near the discontinuity. I would be grateful if someone could shed some light on this.

[@jackrsmusic]

The maths score one is the exactly the same principle. I think you're confused because they showed that graphic of the wide range of maths scores 75th vs 25th. But the RD only looks at the cut off, of students with similar grades but who just get into the school or just don't.

[@mkkkk1643]

do you mean that he used math score as the cutoff? and shrinking bandwidth implies a narrower range of math scores percentile?@@jackrsmusic

👏👏👏👏

[@IsadoreJohnson]

This applied econometric work is REALLY cool. It's a shame that the academic environment seems lifeless and appearing to be not worth getting involved in.

Scott McQuate is the Truth! Thanks for the video(*_*)

[@hakayma7560]

few views but anyway, what I understood that thanks to our -new technology-, we can make progressive changes that were almost impossible to have on a wider scale in the past like the 80s ) thanks

[@user-le7ny8bq1l]

LoL I thought angriest Nobel speech ever.

[@user-sw8nu7zx5t]

Saw your video about child labor and free trade and all I have to say to you is what's nine plus ten.

my brain is fried

[@irsyadhawari]

I've watched this many times but still don't understand.

[@toomanymarys7355]

He totally dropped the high income group when examining exam school enrollment effects. That's because I'd bet hard money that low income ACT scores plummeted while high remained unchanged or improved. Just like he glossed over the negative affect KIP had on higher achieving white kids--it helped the low achievers but depressed the top and shifted the curve left. It is not politically acceptable to say that kids of different backgrounds and aptitudes (not an identical group, of course) succeed under different educational models.
