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...

This paper provides evidence on the long run relationship between European settlers presence and education levels in Algeria. To correct for endogenous sorting of settlers (and natives) into regions I rely on the fact that proximity to the Mediteranean coast determined the timing of conquest and...

This paper provides new estimates of the medium and long-term impacts of Head Start on the health and behavioral problems of its participants. We identify these impacts using discontinuities in the probability of participation induced by program eligibility rules. Our strategy allows us to...

This paper investigates whether unconditional cash transfers can keep refugee children in school and out of work. We raise this question in the unique context of Turkey, which hosts the world's largest refugee population (including 3.6 million Syrians). Refugees in Turkey are supported by the...

This paper investigates the use of self-funded commitment contracts to support individuals in achieving their goals of increased physical activity. We compare the effect of soft (non-incentivised) commitment contracts with hard (incentivised) contracts using a randomised experiment with 1629...

Previous research shows that taste is one of the most important factors in determining food choices, and that food choices may be affected by "nudging". We analyze how taste, as determined by meal attributes, and nudging affects consumption of a healthy labeled meal. Our analysis is based on a...

In vitro fertilization (IVF) has allowed women to delay birth and pursue a career, but it massively increasesthe risk of twin birth. We investigate the extent to which having twins hampers women's careers after birth. To do this, we leverage a single embryo transfer (SET) mandate for IVF...

New institutional economics and organizational theories suggest that the choice of institutional arrangements in service provision should be based on the goods characteristics of the services to be provided. The success of any system whether decentralized public sector or private and...

In this paper, we study the short-run effect of salary receipt on mortality among Swedish public sector employees. By using data on variation in paydays across work-places, we completely control for mortality patterns related to, for example, public holidays and other special days or events...

Despite the fact that Cesarean section (C-section) is the most commonly performed surgery in a number of industrialized countries, little is known about the long-term consequences for the mothers and children involved. In this study, I use a sample of high-risk births—namely, breech births, in...
