The Role of Colleges in Intergenerational Mobility

The fraction of students who come from families in the bottom income quintile and reach the top quintile differs substantially across colleges because low-income access varies significantly, even among colleges with similar earnings outcomes, according to a new study by Raj Chetty, John N. Friedman, Emmanuel Saez, Nicholas Turner, and Danny Yagan. Children from low- and high-income families have similar earnings outcomes conditional on the college attended, indicating that current low-income students are not mismatched at selective colleges.

Juvenile Punishment, High School Graduation
and Adult Crime: Evidence from Judge Harshness

Incarceration as a juvenile has no impact on an individual’s likelihood of committing violent crime in the futur, but it lowers the propensity to commit property crime, according to a study by Ozkan Eren and Naci Mocan. Juvenile incarceration increases the propensity of being convicted for a drug offense in adulthood, but this effect is largely driven by time spent in prison as a juvenile.
