As someone who cried today as I belted the national anthem, after the game, in 2014, and 2018. I don’t want to hear any hate on Luis Diaz or anyone else. The team left it all out there and reminded us all what it was like to believe. Te amo Colombia.
All of this FIFA corruption for Balogun to have one of the worst performances I’ve ever seen. FIFA must bs regretting their decision to bring on this controversy for this

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.

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/

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.

ALL THE LATIN AMERICAN COUNTRIES BEING MENTIONED BY BAD BUNNY IN THE HALFTIME SHOW. #SuperBowl

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

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.
