@Andrew_Semenza But of course, our intuition says that the technology played a key role in the process of learning Similarly, working for a defense co has the intuitive feel of playing a role in the process of killing people, even if the counterfactual is more deaths

@Andrew_Semenza Imagine a new technology that teaches a child to read. But in the absence of the technology, the child’s parents would have taught them to read anyways The (simple) counterfactual theory seems to say the program isn’t responsible for the child knowing how to read

don't really understand the usual moral arguments against working for defense companies. over the past couple decades, it's my sense that improvements in munitions targeting has saved excess casualties on balance (1st order). Is the claim something 2nd order? Or am I mistaken

@sharlappalachia I liked this! I identify a lot w the relationship between your relationship w your parents and them buying you things, especially for me when it comes to their upbringing in scarcity

at least it's on the record in the dissent

On Louisiana v. Callais, a total loss for statistics understanders and win for people who love """controls"""

@TheZvi this is incredible and thought-provoking, thank you for writing this

@sharlappalachia perhaps I should also watch lol

We launch @indevmag with a piece from @PaulFNiehaus on what GiveDirectly’s use of evidence (and a mildly spicy footnote on Paul’s take on microcredit): indevelopmentmag.com/money-for-noth…

@BorelliEcon @JohnRuf6 @BerkeleyHaas @FisherUCB @MSFTResearch Thank you!!

@willwang21 @JohnRuf6 @BerkeleyHaas @FisherUCB @MSFTResearch Congrats. And welcome!

Excited to say I’m moving to the West Coast to start a PhD with the real estate + urban economics group @BerkeleyHaas @FisherUCB this fall! grateful to all of my mentors @MSFTResearch for sticking with me and teaching me everything I know about econ :)

@pasta_nachos this is really cool!

Been a little while since I made a new Chicago misuse of land post and that's because I've been training a segmentation model to draw the polygons for me! go to my public GitHub repo if you want to try it out yourself, and I've got details below:

@abhishekn @BerkeleyHaas @FisherUCB @MSFTResearch Thank you!! Excited to be at Haas

@willwang21 @BerkeleyHaas @FisherUCB @MSFTResearch Welcome!!

@sharlappalachia Well imo the first part is better so…

@sharlappalachia I thought it was good but not extraordinary, very adept but left me feeling like something was lacking

@cmmnknowledge @BerkeleyHaas @FisherUCB @MSFTResearch thank you!! hoping the core is survivable

@willwang21 @BerkeleyHaas @FisherUCB @MSFTResearch congrats!!! and welcome to berkeley!

@gaizweb @BerkeleyHaas @FisherUCB @MSFTResearch Thank you!!

@odavis_ @tysonbrody I'm really skeptical of the exclusion restriction here, Craigslist plausibly has many economic effects than just newspaper closures

@tysonbrody Craisgslist exposure is one of the shocks they use here to show local newspaper deaths raise municipal borrowing rates sciencedirect.com/science/articl…

Wow, a 2025 study found you could connect Craigslist entering a city with a decline in local newspaper staffing, leading to a decline in politics coverage, which in turn led to a decline in readership, which they connect to more partisan voting and extreme candidates.

@asteriskmgzn Are there any more details on what types of pitches you’re looking for related to work?

neeeed someone to do an encouragement design IV analysis of the treatment effect instead
