We subsequently looked at a few of the images I have published, but none were deemed as cool as the Banff data🙃

Andrew Penner @andrewpenner.bsky.social · Aug 24

Kiddo was incredulous and excited when I noted that making pictures to help people understand the world better was my job, and said I could publish this. Kiddo then suggested a division of labor where they would bring me other tidbits like this for me to publish😍

A new article in AERJ observed the relationship between school choice policy and school segregation, finding that White and Asian families disproportionately used the choice system to avoid schools with large concentrations of Black students. journals.sagepub.com/doi/10.3102/...

School choice is both an important tool for school desegregation policy and an enabler of racial segregation. In this paper, we used a two-stage model of comple...

The Power of Attorney flourished when more Americans saw incarcerated people as more than their crimes.

Their career would be unthinkable today: Leaving prison under armed guards to play hundreds of concerts and record in major studios.

For me as a graduate student, @isa-rc28.bsky.social modeled the kind of large-scale, big team, data intensive, methodologically rigorous, theoretically meaningful research that I aspired to do, and so it was especially meaningful to have our work recognized by this award!

As @oliviergodechot.bsky.social notes, in some ways this could be seen as an example of "big" science:
coauthors: 29
years it took: 9
countries: 12
pages (w/ appendices): 111
observations: 1,164,687,821

But it can be summarized in one 5-word sentence: Top earners increasingly work together. PERIOD.

[email protected] @andrewpenner.bsky.social @emilykpenner.bsky.social's book argues for reclaiming absolute goods (vs positional goods) as the desired outcomes of public ed.

I've asked students to pick 2 domains to focus on & explain why. Truly moving responses. Will share when compiled.

Every jailhouse lawyer knows Dee Farmer’s name, even if they don’t know who she is.

What most of them don’t know is that the person who paved the road for them was a transgender woman who filed her suit from a federal prison cell, in an era when her gender identity was considered a mental illness.

In Prison, She Changed Constitutional Law. Meet the Trans Woman Behind the Case.

Farmer v. Brennan is one of the most cited Supreme Court cases of all time. Few people know just how revolutionary Dee Farmer was.

Immigrants in Europe and North America earn 18% less than natives – here’s why

Immigrants struggle to access higher-paying jobs, meaning their skills often go to waste.

Data from nine European and North American countries reveal that the disparity in earnings between immigrants and natives is largely a result of segregation of immigrant workers into lower-paying jobs...

Very excited for the latest paper from the international administrative data network I am a part of!

Led by @aresherman.bsky.social we show that 75% of pay differences between immigrants and native-born workers arise because of sorting into different jobs, with 25% due to unequal pay within jobs.

If you accept that non-citizens have no right to due process, you are accepting that citizens have no right to due process. All the government has to do is claim that you are not a citizen; without due process you have no chance to prove the contrary.
