@btshapir they should have some f****ng introspection !!!

[Alec Stapp @AlecStapp]

GLP-1 drugs are the ultimate validation of the techno-solutionist approach to society's most challenging problems.

The obesity crisis seemed liked it would just get worse and worse forever. Scolding from public health officials didn't work. Proposals to completely overhaul our food systems were dead on arrival.

Instead, we invented a weekly shot (based on Gila monster venom!) that fixes obesity directly.

And now, thanks to the economic incentives in our biomedical industry, we have follow-on drugs that will be cheaper, even more effective, and easier to administer (by taking a pill instead of a shot).

Policymakers should be focused on figuring out how we can get more breakthrough drugs like GLP-1s (and faster). They also should think hard about which slopulist ideas might inadvertently kill the goose that lays the golden eggs.

YES!

I'll just add that the system *can* work this way *right now* without reform. An editor just must be willing to try and the referees need to say yes.

And in my experience trying this exact thing, it's hard to get the referees to agree to have their words made public...

The approach is easily scalable across categories because it does not require category-specific inputs (contrary to characteristics-based approaches). We make our code publicly available here: https://t.co/1pPBbRSEzI [4/4]

... and consistently predicts substitution patterns in real-world data across 40 product categories.

Our approach enables demand estimation even when researchers lack data on product attributes or when consumers value hard-to-quantify attributes such as visual design. [3/4]

I have a new paper. We look at ~all stats articles in political science post-2010 & show that 94% have abstracts that claim to reject a null. Only 2% present only null results. This is hard to explain unless the research process has a filter that only lets rejections through.

[Alex Imas @alexolegimas]

Remember when Milton Friedman would go around and explain basic economic principles clearly and broadly to the public? We need more of that.

Otherwise we're left with public intellectuals who talk about economics for *decades* without knowing even the basics.

@R_Thaler doing great work pushing back, but wow.

Lawsuit ads warn viewers about alleged risks of specific prescription drugs and encourage them to join potential lawsuits. In my paper, now available online at Management Science, I study how such drug injury ads affect drug use and health outcomes.

The Class Gap in Career Progression: Evidence from US Academia

Class is rarely a focus of research or DEI in elite US occupations.

Evidence suggests it should be: we find a large class gap in at least one occupation - tenure-track academia...🧵
