🚨 New pub in @PLOSONE led by @gero5!
Physical therapy is an alternative to opioids for musculoskeletal pain
However, referral requirements may be a barrier
Physical therapy direct access laws were associated with fewer opioid prescriptions

Every time I open this report, I find a new methodological choice to marvel at.
If your model assumes sunshine and rainbows, your result will be sunshine and rainbows.

In their release of the Medicaid work requirements rule, CMS touts an ASPE report as evidence that work requirements increase employment. In fact, the report assumes “illustrative” impacts that are “not necessarily what is or will occur in the real world”. tinyurl.com/2czhrtcw

I find the Paris Saint-Germain construct, controlled by Qatar's sovereign wealth fund, deeply unsympathetic and problematic.
And yet, unlike Arsenal, these players play magnificent football. It is a joy to watch.
Can you separate art from the artist?

Our paper “Difference-in-Differences Designs: A Practitioner’s Guide” is now published in the Journal of Economic Literature. It took us a while but we are happy!
We put together a lot of material to make the paper useful in practice: psantanna.com/JEL-DiD/
Hope you like!

The time has come to raise the housing investment level in this country, just as we did in the 1960s and 1980s.
We have a new report out this morning laying out just how high housing production numbers need to go—and for how many years—to dig us out of the shortage.

loved every second of Bad Bunny. That message of inclusion and a celebration of cultures like Puerto Rico’s is just what America needs right now. Plus, his music just gets you in motion. 10/10

Whenever I meet people who have lived along the Northeast Corridor their whole lives I’m like you don’t know what it’s like out there. It’s bad

To put the horror at Brown in some additional context: Providence is exceedingly unused to gun violence. It is a city of almost 200,000 people with only *two* homicides this entire year, until tonight, down from 11 last year.

Brown University banned guns. Rhode Island has some of the strictest gun control in the nation (AWB, mag restriction, et al). Why didn’t the laws you support, the laws that make innocents completely defenseless, work?

I'm thrilled to see my work with Amy Finkelstein and Matthew Gentzkow coming out in @QJEHarvard! I've learned a lot from reading paper threads, and it's exciting to be able to contribute one of my own

If you're interested in understanding some of the actual economics regarding @JDVance's claim that illegal immigrants are benefiting from Medicaid funding - my paper with @ProfNoto and @talgross is useful.
We show hospitals are in fact a primary beneficiary of these programs.

Multi-brand firms can trap consumers in an illusion of competition, raising prices.
Consumers systematically underestimate brand co-ownership (thinking 9 rival firms compete when it’s really just 4 multi-brand firms).
More brands ≠more competition

Our paper on the economy-wide effects of common ownership is now available on the RESTUD website.
Happy but also a little sad to have closure on this project from which I learned so much!
