New Publication – The long-term effects of long terms

New Publication: “The Long-Term Effects of Long Terms – Compulsory Schooling Reforms in Sweden” by Martin Karlsson, together with Martin Fischer (Karolinska Institute), Therese Nilsson (Lund University) and Nina Schwarz (University of Duisburg-Essen) is published in the Journal of the European Economic Association.


We evaluate the impact on earnings, pensions, and further labor market outcomes of two parallel educational reforms increasing instructional time in Swedish primary school. The reforms extended the annual term length and years of compulsory schooling by comparable amounts. We find striking differences in the effects of the two reforms: at 5% the returns to the term length extension were sizeable and benefited broad ranges of the population. The compulsory schooling extension had small (2%) albeit significant effects, which were possibly driven by an increase in post-compulsory schooling. Both reforms led to increased sorting into occupations with heavy reliance on basic skills and the term extension reduced the gender gap in employment and earnings.
