Statement from Michael and Susan Pretti Parents of Alex Jeffrey Pretti “We are heartbroken but also very angry. Alex was a kindhearted soul who cared deeply for his family and friends and also the American veterans whom he cared for as an ICU nurse at the Minneapolis VA hospital. Alex wanted to make a difference in this world. Unfortunately, he will not be with us to see his impact. I do not throw around the ‘hero’ term lightly. However, his last thought and act was to protect a woman. The sickening lies told about our son by the administration are reprehensible and disgusting. Alex is clearly not holding a gun when attacked by Trump’s murdering and cowardly ICE thugs. He had his phone in his right hand and his empty left hand is raised above his head while trying to protect the woman ICE just pushed down, all while being pepper sprayed. Please get the truth out about our son. He was a good man. Thank you.

Kare 11 local news just read, in full, this statement from Michael and Susan Pretti, the parents of Alex Pretti.

"Please get the truth out about our son."

“Are you okay?”
“I’m not even mad at you, dude.”

Compared with their killers’ remarks:

“Boo hoo.”
“Fucking bitch.”

Protester in Minneapolis just before disappearing in gas: "Fuck you! Stop. Damn! I'm 70 years old and I'm fuckin' angry!"

One of my strongly-held beliefs is that this country will be far worse off if we end up with a dichotomy between an explicitly religious right and a self-consciously secular and even anti-religious left. To that end, I am heartened to see the number of clergy rising to action against ICE.

I don't know what her religious views were and of course that's not the point, but this is what actual Christian martyrdom looks like.

/2 In light of that, I am in awe and deep respect of the people who are still showing up to monitor the ICE Gestapo, protect and defend their neighbors, do whatever they can to hold ICE to account and call out their lawlessness. What incredible bravery.

Catholic Vice President Vance takes to social media to justify killing of Renee Good After the tragic shooting of Renee Good at the hands of ICE, the Catholic vice president of the United States took to social media to justify the killing.

Editorial in the National Catholic Reporter: "The vice president's comments justifying the death of Renee Good are a moral stain on the collective witness of our Catholic faith. His repeated attempts to blame Good for her own death are fundamentally incompatible with the Gospel."

Hey #econsky! I'm organizing a workshop at Brown this Spring in partnership with Eric Nielsen and Viviana Rodriguez.

The topic is educational measurement. Please submit a paper/extended abstract! We'd love to consider your work.

And please help us spread the word to folks who aren't on bluesky!

A pro-affordability, anti-Trump-corruption message unites the party. Every candidate can run on that, and every candidate can have their own take to fit that to their constituents. There's really no need to find fights to pick when the party agrees on more than it disagrees

@jessebruhn.bsky.social, Sai, and I are almost done with a paper that jointly estimates teacher VA and school VA. We're finding (in NC) school test effects of about .08 student SDs and that ~30% of that is due to variation in avg. teacher quality across schools.

This situation is so so sad. But I've finally remembered that doing something, however small it seems, is better than doing nothing. I set up a recurring donation and would encourage others to consider doing so as well.

Miami clergy raise concerns as Trump tours Florida's 'Alligator Alcatraz' - Catholic Review Most Americans agree on the need for good U.S. border security, but to hear politicians and civil authorities hurl insults and jokes at the expense of migrants as Florida opened its new "Alligator Alc...

Miami, FL Catholic priest Father Federico Capdepón: “To have this Alligator Alcatraz is a very sinful initiative — to say nobody can escape because the gators are around is very sinful.”

like the old joke about being a liberal when you're young and a conservative when you're old:

"if you didn't have trump derangement syndrome in the first admin, you have no heart; if you didn't have trump derangement syndrome in the second admin, you have no brain"

obviously this is terrible for democracy and the rule of law in America

but I'm also offended on behalf of the prisoner's dilemma

this from a representative at American Institutes for Research about DOGE/Trump cancelling IES contracts is spot on (& good on them for speaking out clearly about this)

Step 1: Don’t doom on the timeline.
Step 2: Don’t doom at all.
Step 3: Do things. Small things count.
Step 4: Repeat forever.

This is both exhausting and liberating.

It's not quite that, but I believe Bruce Sacerdote has a study using random adoption matching to get at it a bit.

"You either play hide and seek with me now, or pay for my psychologist in 5 years. Your choice daddy."

Isn't "fucking around at margins" more or less the definition of economics?

(Also, stop trying to guilt me to spend more time with my kids. They're good enough at that on their own, thank you very much.)

It's not just a question of "which matters more" from a causal inference sense but also "which can we use public policy to improve," no?

I've always wanted to meet the magical whiskey fairy. I'm ashamed to admit that I even started to doubt whether she actually existed, but you've given me hope Jesse.

I think a big part of it is that it's really hard to separate teacher effects from school effects, which you need to do if you really want to understand sorting. I'm working on a paper that tries to do that, in part to answer the sorting question, but it's a tricky empirical question.

4/ What makes me most excited about this work is that I think it can also be a useful building block for estimating effects in other complicated settings, such as averaging RCT and non-RCT estimates, RDs, judge IVs, etc.

So definitely let me know what you think of it, good or bad!

3/ Even more interesting, it turns out we can decompose the resulting posterior variance into that generated by traditional statistical uncertainty vs extrapolation uncertainty.

Much to my surprise, even in the huge Oregon Medicaid experience the statistical uncertainty seems to dominate.

2/ The basic idea is that by adding a Bayesian hierarchical model to traditional econometric models of selection, we can generate estimates/CIs of the ATE (or other estimands) that capture uncertainty in both the true values of the observed moments and uncertainty in how to extrapolate from these.

From LATE to ATE: A Bayesian approach We develop a Bayesian model that produces a posterior distribution of the marginal treatment effect (MTE) function. The method provides researchers wi…

1/ Want to estimate the average effect of a treatment rather than restricting your estimate to the compliers?

My paper just out in the Journal of Econometrics gives you another tool, with an R package available on GitHub!

Isn't it partly a question of what you hold fixed and what is considered random when thinking about inference? E.g. if the size of spillovers depends on who is grouped, then it depends on treatment assignment and so cluster? If not, then they're fixed and so you don't need to cluster?
