About me

I am a professor of Economics at SOFI, Stockholm University. My research interests include labor economics, currently with a special focus on disability (study 6, 7 and 9) and public meals (study 1 and 10).  I also study discrimination, health economics and economics of education.

  • Disability, gender, and hiring discrimination

    Article
    2025. Vegar Bjørnshagen, Dan-Olof Rooth, Elisabeth Ugreninov.

    This article examines disability discrimination in the hiring process and explores variation in how the intersection of disability and gender shapes employers’ hiring behavior. We use data from a field experiment in which 2,048 job applications with randomly assigned information about disability were sent to Swedish employers with vacancies. Nondisabled applicants received 33% more callbacks than similarly qualified wheelchair users despite applying for jobs for which the impairment should not interfere with performance. The results indicate no heterogeneity in disability discrimination against men and women on average across occupations or by occupational gender segregation. However, discrimination rates differ considerably among occupations, varying from no evidence of disability discrimination to discrimination against both disabled men and disabled women as well as cases in which disability discrimination is found only against women or only against men. The results indicate that discrimination based on disability, and the intersection between disability and gender, is highly occupation specific.

  • Employers' Language Proficiency Requirements and Hiring of Immigrants

    Report
    2025. Magnus Carlsson, Stefan Eriksson, Dan-Olof Rooth.

    Labor markets in advanced economies have undergone substantial change due to globalization, technological improvements, and organizational changes, making language proficiency increasingly important even in less skilled jobs. Has this development led employers to shy away from hiring immigrants with limited host-country language skills? We shed light on this question by conducting a large-scale field experiment, where we introduce common second-language features in immigrants’ resumes. We also conduct employer surveys to interpret our experimental results. Our main finding is that language proficiency has a strong positive effect on being invited to a job interview, even in typical immigrant entry jobs.

  • Work from Home and Disability Employment

    Report
    2025. Nicholas Bloom, Gordon B Dahl, Rooth Dan-Olof.

    There has been a dramatic rise in disability employment in the US since the pandemic, a pattern mirrored in other countries as well. A similar increase is not found for any other major gender, race, age or education demographic. At the same time, work from home has risen four-fold. This paper asks whether the two are causally related. Analyzing CPS and ACS microdata, we find the increase in disability employment is concentrated in occupations with high levels of working from home. Controlling for compositional changes and labor market tightness, we estimate that a 1 percentage point increase in work from home increases full-time employment by 1.1% for individuals with a physical disability. A back of the envelope calculation reveals that the post pandemic increase in working from home explains 80% of the rise in full-time employment. Wage data suggests that WFH increased the supply of workers with a disability, likely by reducing commuting costs and enabling better control of working conditions.

  • Intergenerational and Sibling Spillovers in High School Majors

    Article
    2024. Gordon B. Dahl, Dan-Olof Rooth, Anders Stenberg.

    This paper estimates family spillovers in high school major choice in Sweden, where admission to oversubscribed majors is determined based on GPA. Using a regression discontinuity design, we find large sibling and intergenerational spillovers that depend on the sex mix of a dyad. Same-sex siblings copy one another, while younger brothers recoil from an older sister's choices. Fathers and mothers influence sons but not their daughters, except when a mother majors in the male-dominated program of engineering. Back-of-the-envelope calculations reveal that these within-family spillovers have sizable implications for the sex composition of majors.

  • Weight, attractiveness, and gender when hiring

    Article
    2024. Catarina Goulão, Juan Antonio Lacomba, Francisco Lagos, Dan-Olof Rooth.

    Being overweight or obese is associated with lower employment and earnings, possibly arising from employer discrimination. A few studies have used field experiments to show that obese job applicants are, in fact, discriminated against in the hiring process. However, whether overweight job applicants also face employer discrimination is still an open question. To this end, we have designed a correspondence testing experiment in which fictitious applications are sent to real job openings across twelve different occupations in the Spanish labor market. We compare the callback rate for applications with a facial photo of a normal weight person to the one for applications with a photo of the same person manipulated into looking overweight.Applications with a photo of the weight-manipulated male receive significantly fewer callbacks for a job interview compared to normal weight, and this differential treatment is especially pronounced in female dominated occupations. For women, we find the opposite result. Weightmanipulated female applications receive slightly more callbacks, especially in female dominated occupations. Our experimental design allows us to disentangle whether employers act on attractiveness or weight when hiring. For men, the weight manipulation effect is explained by an attractiveness premium, while for women we find evidence of an attractiveness penalty, as well as a weight penalty, in explaining the effect.

An Evaluation of Higher Vocational Education

This project aims to provide the first comprehensive economics evaluation of Higher Vocational Education (Yrkeshögskolan). Four separate studies test if HVE influences participant’s labor earnings, participant’s likelihood of employment, occupational or geographical mobility, and the marginal participant’s labor earnings.

Newly arrived refugees’ labor market integration

A study of measures in the establishment mission and how these affect employers’ recruitment decisions. The integration of refugees into the regular labor market takes a very long time. After eight years in Sweden, only about half are employed. The objective of the project is to study refugees' path towards employment the first years after arrival.

Long term causal effects of upper secondary school program

This project aims at evaluating long term causal effects of educational contents on voter turnout and health outcomes, as well as to analyze the determinants of educational choices. Educational contents is an underdeveloped area of research although it is widely assumed to affect a number of outcomes.
