Several countries practice a system where laymen, who lack legal education, participate in the judicial decision making. Yet, little is known about their potential influence on the court rulings. In Sweden lay judges (namndeman) are affiliated with the political parties and appointed in...

Although economic circumstances have been argued to be a major determining factor of attitudes to redistribution, there is little well identified evidence at the individual level. Utilizing a unique dataset, with detailed individual information, provides new and convincing evidence on the link...

Students in East-Asian countries consistently score in the top in international assessments. One possible explanation for this success is their use of 'Lesson study' to enhance teaching practices, but evidence on its effectiveness is still scant. We evaluate a national teacher development...

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 exploits exogenous variation in the price of child care stemming from a major child care price reform, to estimate the effects of child care costs on parents’ labour supply. The reform introduced a cap on the price that local governments could charge parents, and lead to...

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...

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...

In many countries welfare services that traditionally have been provided by the public sector are increasingly being contracted out to private providers. But are private contractors better at providing these services? We use a randomized experiment to empirically assess the effectiveness of...

Using a Difference-in-Differences approach we evaluate the effects of a 10 percentage points reduction in the payroll tax introduced in 2002 for firms in the northern part of Sweden. We find no employment effects for existing firms and can rule out that a 1 percentage point payroll tax reduction...

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...
