In this paper we investigate whether a relaxation in seniority rules (the last-in-first-out-principle) had any effect on firms' employment behaviour. Seniority rules exist in several countries and, like Sweden, most European countries have a more lenient employment protection for firms below a...

We examine the relationship between unemployment benefits and unemployment using Swedish regional data. To estimate the effect of an increase in unemployment insurance (UI) on unemployment we exploit the ceiling on UI benefits. The benefit ceiling, coupled with the fact that there are regional...

We utilize a large-scale randomized social experiment to identify how coworkers affect each other's effort as measured by work absence. The experiment altered the work absence incentives for half of all employees living in Göteborg, Sweden. Using administrative data we are able to recover the...

The matching method for treatment evaluation does not balance selective unobserved differences between treated and non-treated. We derive a simple correction term if there is an instrument that shifts the treatment probability to zero in specific cases. Policies with eligibility restrictions,...

This paper examines if the probability of leaving unemployment changes for unemployed parents with young children when childcare is available. To investigate this, I use the heterogeneity among Swedish municipalities before the implementation of a 2001 Swedish childcare reform making it...

In observational studies, the estimation of a treatment effect on an outcome of interest is often done by controlling on a set of pre-treatment characteristics (covariates). This yields an unbiased estimator of the treatment effect when the assumption of unconfoundedness holds, that is, there...

Since the mid-20th century many OECD countries have discarded their previous selective schools systems, in which students early on were separated between academic and vocational tracks, in favor of more comprehensive schools. The effects of these reforms have generally been difficult to evaluate...

This paper investigates the consequences of a series of Swedish policy changes beginning in 1989 where different regions started subsidizing the birth control pill. The reforms were significant and applied to all types of oral contraceptives. My identification strategy takes advantage of the...

Swedish elementary school children stopped receiving written end of year report cards following a grading reform in 1982. Gradual implementation of the reform creates an opportunity to investigate the effects of being graded on adult educational attainments and earnings for children in the...

This study examines the extent to which wage-earning workers are simultaneously self-employed, a phenomenon not thoroughly investigated in earlier studies. We use matched employee-employer databases to present a detailed investigation of self-employment patterns within the post industrial...
