Really excited to share that both my better half (@bfoxwilliams) and I were selected as 2024-25 @RussellSageFdn Visiting Scholars. Looking forward to joining such an impressive group of scholars.

@JohnRuf6 @VincentGeloso @joefrancis505 I’ll let you have the last word, but I don’t find your latter statement to even remotely be true. If you don’t believe that an equal amount of fuckery is possible with RD, IV, D-i-D, etc. then I have a bridge in Brooklyn to sell you. Lol
English
@MWillJr @VincentGeloso I mean for specific pointed critiques there's a lot flying around like @joefrancis505's recent post.
My point here is more sociological insofar that it's easier to use this technique "sloppily" and wriggle your way around peer review.
English
I think scm just has massive "human in the loop" problems that takes a incredible level of faith in the researchers that is rare to see in practice. Similar to IV papers and to a lesser extent DID.
Vincent Geloso@VincentGeloso
I replied here. But the simple story is that people dont lile case studies which is fair. But SCM improved case studies massively. Opening the door to major clarifications and also possible remedies (jacknife test, donor pool rotations, SDID, etc.). All issues that apply to all other methods (SUTVA per eg) apply here too. Haters probable motivate their hate by reasonable cases of bad papers (I have six in mind and @ez_angus can name names too) but they’re about execution, setting etc. Nothint about the method per se
English
@JohnRuf6 @VincentGeloso I’m failing to see the specific econometric critique that you’re making against SCM other than if you performed it sloppily it’s not useful—which is true for many other estimators as well.

@VincentGeloso @MWillJr And if that's all it brings to the table then I should treat it about the same as eyeballing, which is to say not convincing.

My paper "Work Hours Mismatch" with @MartaLachowska @raffaelesaggio and Steve Woodbury is now in print at Econometrica.

@VincentGeloso @JohnRuf6 Yea I’m with Vincent here. Not seeing how researcher “degrees of freedom” differ across (say) SCM and D-i-D.
English
@JohnRuf6 Researcher degrees of freedom-problem is applicable to all methods! I agree

So proud to celebrate my father @metrics52 at his Festschrift -- a gathering of people and presentations in honor of his career and legacy. He has influenced so many: generations of Angrists and a rockstar student family tree. An impressive array of causal effects!

If you weren't there for the dark ages of:
• Chris Duhon
• Howard Eisley
• Glen Rice
• Shandon Anderson
• Clarence Weatherspoon
• Malik Rose
• Jared Jeffries
• Renaldo Balkman
Then today’s success doesn’t mean as much to you. We really survived the shit of the shit.

@mattyglesias Outside of “staying away from identity politics,” I am not entirely sure that there is a plan.

The question as ever is what will Democrats do to welcome voters disillusioned with Trump but who didn’t like the Biden administration and felt Harris was too much continuity with a policy program they rejected.
.@GregTSargent
Little by little, Trump is shrinking MAGA down to its molten core. *Alienating noncollege/rural whites *and* Latinos/young *Forcing disloyal Rs out of GOP *Demanding Rs fund ballroom *Insisting Rs defend 1/6 slush fund *Wrecking economy with tariffs/war newrepublic.com/article/210855…

@CPTheFanchise “Swarming and warming.” I dunno bro.
Let’s go Knicks!

I have largely avoided posting on this app for a long time. How is everyone doing?
English
@CoachMcCartan You’re right. He should have dragged the franchise into a public, political campaign rally featuring the most corrupt administration in U.S. history first. Oh wait….
English
Wrong order of operations here on Carter’s part, but I’m glad they worked it out.
Abdul Carter@1NCRDB1
Me & JD6 are good! We spoke earlier as Men. Yall can keep yall narratives.

@Noahpinion I see your “the Black-White racial conflict is petering out as both groups age and decline” and raise you a gutting of the Voting Rights Act.
English
The Black-White racial conflict is petering out as both groups age and decline. The new battle is right-wing working-class Latinos versus elite South Asian Islamoleftists

Wesley Yang@wesyang
The great irony that undergirds both the Great Awokening and Trumpism is that the conundrum of affirmative action has now simply been replaced by the browning of America. The black underclass, the astroturfed civil rights elite, have both been demographically overtaken by a Hispanic working class and the tribunes of Mamdani-ism for whom Palestine and not Selma is the lodestar of the omnicause.
English
@mattyglesias They made the Mandalorian and Grogu movie the first Star Wars movie on the big screen since The Rise of Skywalker. They have run this franchise into the ground.
Also, Maul was great but I would be OK not seeing another story between episodes 3 and 4 in my lifetime…
English
Ten years ago, it would have been inconceivable to me for the release of a new Star Wars feature film to be this little of a big deal.
The Last Jedi / Rise of Skywalker fiasco destroyed a staggering amount of cultural and economic value.
English
@CarlBanksGIII @JEVos17 Carl, you are one of the most thoughtful Giants legends of all-time. Is it more so that you don’t care or don’t care to share your opinion (which I respect)? It’s hard for me not to care when the Voting Rights Act has been gutted and federal agents took American lives last year.
English
@RalphVacchiano Ralph, “politics are divisive” works for minimum wage debates. The immoral actions of this administration are common knowledge. Dart endorsed these actions as soon as he stepped on stage and invoked the franchise at a campaign rally. He deserves unilateral blame as a team leader.
English
... Politics today are divisive. Jaxson Dart publicly taking a side comes with consequences. Same with Abdul Carter's reaction. You can already see how divisive it is amongst fans. It'll be the same amongst players.
The coach has to stop it before it becomes a problem.
English
This is a reasonable assessment of the Jaxson Dart-Abdul Carter stuff. In the end, what happens on the field will matter the most inside the locker room.
But don't underestimate how much this will test the culture John Harbaugh is trying to build. ...
Benjamin Watson@BenjaminSWatson
The football impact of Jaxson Dart’s decision to introduce POTUS depends on the health of the Giant’s organization culture. The locker room is like any other workplace. Employees have different religious and political affiliations. However, in the league there is an openness and willingness to engage with those who think differently. Success on the field is often the direct result of trust and transparency between the lines and beyond. Every team member has the right to believe what they want and support who they want and a responsibility to do so in a way that honors their convictions and respects the other members. Whether it was Trump or Biden a healthy culture is transparent enough to be unfazed by the outside noise and committed enough to address any concerns internally. - Harbaugh’s first culture test. For those who didn’t want to read all that: Dart’s decision was his. Some teammates will question others will support but delivering the ball on time and converting 3rd down is more important. They know him, we don’t.
English
@BrandonTierney So Dart gets to participate in a *public campaign rally*, but Carter is not equally entitled to make his disdain for this *political* event known? Sounds like it’s first amendment rights for some athletes and “shut up and dribble” for others….
English
@geneclemons They make it really hard not to believe that there are two sets of rules for Black and White athletes:
- White athletes get first amendment rights in the form of public campaign rallies;
- Black athletes get first amendment rights in the form of “shut up and dribble.”
English
Lawrence Tynes is completely tone deaf right here. He's doing what he claims Carter is doing except Carter has every right to be dumbfounded by the actions he addressed. This is not something he saw in the lockerroom and brought to the public, this was done for the world to see.
Lawrence Tynes@lt4kicks
The locker room is a sacred place because it brings together everyone from all walks of life and beliefs for one common goal. Calling a teammate out publicly for his political views and to get attention is nasty work.
