This paper shows that children are significantly less likely to enter the academic track if they come from a low socio-economic status family. A low-intensity mentoring program can improve long-run education outcomes of disadvantaged children and reduce inequality of opportunity.

Enduring competitive pressure not only changes young people's behaviour, but also their personality: they become less prosocial. New paper @fabiankosse.bsky.social et al. @jeeanews.bsky.social #prosociality

A preferential college admission programme in #Chile increased enrolment in selective colleges but reduced pre-college academic effort and test scores due to student misunderstanding.

Graph showing the effect of PACE on admissions and on enrolment or graduation over time.

Preferential college admission is gaining traction worldwide as a means to address inequality in higher education, drawing greater attention to the design of such policies. This column analyses a programme for disadvantaged high schools in Chile that offers guaranteed college admission to top-performing students. The programme increased enrolment in selective colleges but reduced pre-college academic effort and test scores as students incorrectly believed college admission was guaranteed. Addressing students’ misunderstandings could mitigate the negative incentive effects while preserving the policy’s enrolment benefits.

Enduring competition makes people less cooperative. A 2-year competition in schools made students less prosocial (less willing to help or cooperate). Even 4 years later, the effect was still there, suggesting it changed their personality traits, not just their short-term behavior

Johannes Abeler, Armin Falk, and I are thrilled that The Economic Journal accepted our paper titled ‘Malleability of Preferences for Honesty.’ It explores how the social environment influences lying. Huge thanks for a fast and productive referee process! 🥳
