Good teachers don't just raise the achievement of students they teach. They also shape the teachers of tomorrow.
Standard estimates of teacher impact ignore these intergenerational spillovers. Thread on new work led by @danilok.bsky.social.

7/7 Check the paper, it is open access!
The goal was to provide a comparative analysis of stratification/segregation in the most descriptive and reader-friendly way possible, hopefully interesting for a broad audience. Personal experience: it is a big challenge.
6/7 Implications for equity.
Expanding access and reducing financial barriers may be insufficient if resources remain concentrated in institutions that disproportionately enroll affluent students.
5/7 Research matters, but mainly in the public sector.
In public sector, disparities are linked to universities’ research intensities. In the private sector, high-income niches generate higher resources regardless of research. (Figure shows the SES resource gap controlling for different factors.)
2/7 How unequal are university resources?
Despite having high income inequality, Brazil and Chile show moderate resource stratification by international standards. Brazil’s Gini index is 0.35 and Chile’s is 0.28, below the U.S., Italy, the UK, Sweden, and others.
3/7 Student segregation is much higher in Chile.
The dissimilarity index is 0.42 in Chile vs. 0.25 in Brazil. In Chile, high-income students (top 20%) make up around 80% of the enrollment of the most segregated universities.
1/7 🚨 New paper out in @sociusjournal.bsky.social !
I study how the unequal distribution of financial resources across universities in Brazil and Chile overlaps with the unequal distribution of students from different SES background.

4/7 + link between resources and segregation
Universities enrolling more high-income students spend more per student, especially in the public sectors. This contrasts with school funding systems allocating more resources to schools with more low-income students.
Wealthy universities enjoy advantages in accessing resources, disproportionately benefiting high-income students who are overrepresented in these institutions. ...
