Tennis is so funny because you’ll wait all week to play just to double-fault 15 times

I’m starting a new substack. My focus will be, as always, on K12 education, but I'll also explore how the education system interacts with our economic system and our earth system. Please help me spread the word. It will always be free. matthewakraft.substack.com/p/introducin...

Agreed it’s likely underpowered. But the pattern is still interesting: the point estimate is fairly large and negative. Plus the 5 pp employment dip in years 5-7. To me, the consistent negative result suggests some sort of labor market substitution that isn’t outweighed by the degrees T group earns

That’s easy to do in Stata, you just need to access an invisible, cryptically-named matrix that requires learning a different programming language to view

Anyone else not a fan of Overleaf's new editor tab system?

Good luck on the market! I’m in a similar phase and have similar feelings. It’s humbling to reflect on the process and difficult not to fixate on the anxiety of what might be next

An excellent circle graph showing occupations of Black and white people in Georgia

Today, I signed an Executive Order temporarily repealing bedtimes in the City of New York so that kids of all ages can watch our team in the NBA Finals. As Mayor, you’re forced to make many difficult decisions. This was not one of them. Go Knicks.

Probably better to start them with Frisch-Waugh-Lovell to build up some intuition

I’m always astonished to look at other countries that manage to have country-wide curricula and standardized assessments… in some Latin American countries you can even access student-level data for these things publicly!

I actually can’t believe the Knicks are in the finals 🥲

Sometimes working on an RCT outside the U.S. feels too far afield from my work with state longitudinal datasets, but it also comes with some perks!

Really interesting piece. While a fair number of ed policy folks have tossed around the idea of bringing back ed reform, I don’t see the political will for a project like this at the moment. Something - perhaps not unlike A Nation at Risk - will need to happen first

I think Lankford et al. (2002) has some really strong descriptive tables: journals.sagepub.com/doi/10.3102/... I find the one below really powerful: Teachers who switch schools within a district tend to move to similar schools, while those who switch districts move to more advantaged schools

Table from a study of teacher transfers in New York City (1993–1998) comparing characteristics of “sending” vs. “receiving” schools. Columns show within-district and between-district moves, each with sending school, receiving school, and the difference.
Within districts, differences are small (e.g., slightly lower poverty and nonwhite share in receiving schools, minimal class size change). Between districts, differences are large: teachers move to schools with far lower poverty (−0.468), fewer nonwhite students (−0.482), fewer English learners (−0.091), smaller class sizes (about 5.8 fewer students), and higher salaries (about $4k–$7k more). Most between-district differences are statistically significant.

Extreme emphasis on internal validity strikes me as the most plausible explanation

Amen - folks put a lot of weight on the results from some elite institutions that surely had little variation in GPA across matriculates
