We examine the changes in the rewards to cognitive and non-cognitive skill during the time period 1992-2013. Using unique administrative data for Sweden, we document a secular increase in the returns to non-cognitive skill. This increase is particularly pronounced in the private sector, at the...

We study the intergenerational transmission of cognitive and non-cognitive abilities between parents and sons using population-wide enlistment data. Conscripts are evaluated at the same age and with comparable methods across cohorts, and we correct for measurement error bias in fathers' ability...

We study differential parental responses to variation in class size induced by a maximum class size rule in Swedish schools. In response to an increase in class size: (i) only high-income parents help their children more with homework; (ii) all parents are more likely to move their child to...

In Sweden, children typically start compulsary school the year they turn seven. Individuals born just before or just after the new year, have about the same date of birth but start school att different ages. We exploit this source of exogenous variation, to identify the effects of age at school...

This paper utilizes a policy change to estimate the effect of teacher density on student performance. We find that an increase in teacher density has a positive effect on student achievement. The baseline estimate – obtained by using the grade point average as the outcome variable – implies...

This paper evaluates the long-term effects of class size in primary school. We use rich administrative data from Sweden and exploit variation in class size created by a maximum class size rule. Smaller classes in the last three years of primary school (age 10 to 13) are not only beneficial for...
