Jenny Jans

Welcome! I am a researcher at the Swedish Institute for Social Research at Stockholm University. I completed my Ph.D. in Economics from Uppsala University in 2017. My research interests broadly covers health, environmental, and labor economics and is primarily empirically oriented. Much of my current work is focused on the impact of poor environmental quality and the relationship between the environment, health, and human capital formation.

I am part of the Heavy Metal Project where we study the effects of exposure to toxic heavy metals on long-term human capital development and labor market outcomes.

Air Pollution and Health at Birth - Evidence from Sweden

This paper studies the effect of air pollution on infant health in Sweden. Combining register data on birth outcomes and family characteristics with pollution data, I estimate the effect of particulate matter (PM10) on several birth outcomes that previously have been shown to be predictive of future outcomes. The results suggest that pollution adversely affects infant health (birth weight and gestational length). Moreover, quantile estimates suggests that the effects are larger in the lower tail of the health distribution. The effect is stronger both among children from low income households and among children born to mothers who smoke. I also find suggestive evidence of non-linearities in the relationship between PM10 and health at birth.

Economic Status, Air Quality, and Child Health: Evidence from Inversion Episodes with Per Johansson and J Peter Nilsson

Journal of Health Economics, Vol.61. September 2018 (Older version: IZA Discussion paper 7929, January 2014 )

Normally, the temperature decreases with altitude, allowing air pollutants to rise and disperse. During inversion episodes, warmer air at higher altitude traps air pollutants at the ground. By merging vertical temperature profile data from NASA with pollution monitors and health care records, we show that inversions increase the PM10 levels by 25% and children’s respiratory health problems by 5.5%. Low-income children are particularly affected, and differences in baseline health seem to be a key mediating factor behind the effect of pollution on the SES health gap. Policies that improve dissemination of information on inversion status may hence improve child health, either through private action or via policies that curb emissions during inversion episodes.


Parental Leave Benefits, Household Labor Supply, and Children’s Long-run Outcomes with Rita Ginja and Arizo Karimi

Journal of Labor Economics, Vol. 38. No. 1, January 2020

We study how parental leave benefit levels affect household labor supply, family income, and child outcomes, exploiting the speed premium (SP) in the Swedish leave system. The SP grants mothers higher benefits for a subsequent child without reestablishing eligibility through market work if two births occur within a prespecified interval. We use the spacing eligibility cutoffs in a regression discontinuity framework and find that the SP improves educational outcomes of the older child but not those of the younger. Impacts are likely driven by increased maternal time and the quality of maternal time relative to the counterfactual mode of care.
