New Publication – Education and Health: Long-Run Effects of Peers, Tracking and Years

New publication: “Education and health: long-run effects of peers, tracking and years” by Martin Karlsson, together with Martin Fischer (Karolinska Institute), Ulf Gerdtham (Lund University), Gawain Heckley (Lund University), Gustav Kjellsson (University of Gothenburg) and Therese Nilsson (Lund University) is published in Economic Policy.


We investigate two parallel school reforms in Sweden to assess the long-run health effects of education. One reform only increased years of schooling, while the other increased years of schooling but also removed tracking leading to a more mixed socioeconomic peer group. By differencing the effects of the parallel reforms we separate the effect of de-tracking and peers from that of more schooling. We find that the pure years of schooling reform reduced mortality and improved current health. Differencing the effects of the reforms shows significant differences in the estimated impacts, suggesting that de-tracking and subsequent peer effects resulted in worse health.
