We really appreciate @Jess_Hoel for letting me test this material out on her students, and @SandyDarity, @TrevonDLogan and others for great feedback and support!

When we've tried this curriculum with our students, we've gotten some really good discussions. If any of you think you might want to try out these lectures, don't hesitate to reach out! we'd also love to feature examples on our website:

Last, we present an example of a real-world scenario that can be understood using this model. In the paper, we talk about the Tulsa Race Massacre, but we've created a website with other examples. I've taught this using the sale of the Crenshaw Mall in Los Angeles.

We use simple welfare diagrams to show the cost to individual employers and the benefit to employers collectively from discriminating, and use game theory to discuss when employers may act collectively. We have a more complex (but messier) version here:

"Stratification Econ" notes that, even if discrimination is costly for any particular employer, it can lower collective labor costs by suppressing the wages of marginalized workers. So if employers act in their *collective* best interest, they may choose to discriminate.

Most undergrad econ of discrimination starts by assuming that employers who discriminate pay more for labor by not hiring the cheapest worker available. Since firms that don't discriminate have lower costs, competitive pressure should push discriminators out of the market.

Our paper presents an approach to teaching the core ideas of "Stratification Economics" using simple welfare analysis and game theory. The intention is that it can slot into an intro or intermediate class right after discussion of standard discrimination models.

Very pleased to see my work with Mary Lopez published today in the Journal of Economic Education, presenting a strategy to broaden discussion of discrimination in introductory economics: https://t.co/7OsuIiQJq8

Early view from JPAM: "The long-run effects of temporary protection from deportation" by @JorgenHarris (@Occidental) & @RJerch (@UW_AAE) https://t.co/JgD5tQKxki

That even a limited policy allows recipients to improve their economic position highlights how difficult it is to live without documentation. Thank you Rhiannon for being a wonderful coauthor, @smithtjosh and the @cgousu for supporting the work, and @JPAM_DC for publishing it!

TPS is very limited--recipients can legally work and live in the US for 18 months at a time, but there's no pathway to permanent legal status. There's no guarantee that TPS will be extended from year to year, so recipients live with the treat of deportation.

Salvadoran immigrants received Temporary Protected Status after a series of earthquakes in 2001. Likely-undocumented Salvadorans and Guatemalans had similar levels of income prior to 2001, but Salvadorans earned higher incomes for 20 years after getting TPS.

Very nice writeup of a project that Seva Rodnyansky and I have been working on for a few years. This came from collaborations with local groups that wanted to understand policing in their communities, and with five fantastic undergrads. https://t.co/vzQBM9m2Sz

And, thank you to my wonderful coauthors, Eleonora Patacchini and Marco Battaglini! @m_battaglini

Thank you to the Faculti team for the chance to talk about my work! It was a lot of fun doing this interview. To my legion of followers: this is a rare opportunity to hear me go on and on about my work--you don't want to miss it :)

Wow what an interesting paper! I bet the authors are extremely intelligent.

❓ Does working closely w/ ppl from underrepresented backgrounds change attitudes of ppl from majority backgrounds? @m_battaglini @JorgenHarris @EleonoraPatacc2 look at Federate Appellate Courts to answer this Q. Read their research summary ➡️ https://t.co/29FQzGu8iO @EconUCL

Pleased to announce that my work on the relationship between children's safety and parents' approach to discipline is out at the Review of Black Political Economy. This was my first research idea, 10 years ago! https://t.co/pTE5klywPS

Letting everyone earn driver's licenses regardless of immigration status makes everyone safer on the road. We just released @AmuedoDorantes and @EDziadula's new research here at @cgousu! https://t.co/yRR5xXb2Ci

It's so gratifying to have this work out in the world. Thankyou @RJerch for being an amazing coauthor, and thank you to Josh and the CGO for helping us get this out there!
