We use the 2006 Qu'ebec paternity leave reform to replicate Dahl et al., 2014 who estimate the peer effects of paternity leave taking among male co-workers. The Qu'ebec reform of the paternity leave system closely resembles the Norwegian 1993 reform they analyze. Using high-quality...

We study the effect of having high socioeconomic status (SES) peers on pupils' wellbeing, absence rate, and academic performance in elementary school. We compare pupils in the same school who started school in different years and, consequently, were exposed to different shares of high-SES peers....

In the 1960s and 1970s elite studies formed an integral part of the research agenda on newly independent African states. Commentators sought to predict the likely political and economic paths of independent African states based on the social backgrounds and political orientations of existing...

We use the National Longitudinal Study of Adolescent to Adult Health to explore how high school peers’ grit, a personality trait characterized by perseverance and passion, influences long-term outcomes approximately 15 years after high school. Exploiting random variation within schools across...

We study how poorly-behaved children affect learning and other outcomes of their peers using data from a unique experiment in Ecuador. Within each school, students were randomly assigned to classrooms in every grade for seven consecutive grades, between kindergarten and 6th grade. Children with...

Standard economic models view labour supply decisions as individual utility maximisation balancing the trade-off between income and leisure. In contrast, we focus on the social context as a central determinant and analyse how colleagues' working hours shape individual working hours preferences....

We examine teachers’ perceptions toward top performing students and their role model influence on others in an online survey-based experiment. We randomly expose teachers to profiles of top performing students and inquire whether they consider the profiled top performers to be influential role...

Economic theory predicts that dishonesty thrives in secrecy. Yet, team-based decisions are ubiquitous in public policy-making. How does teamwork influence the tendency for selfdealings when public servants – both honest and corrupt – must work together to make decisions under the veil of...

We examine teachers’ perceptions toward top performing students and their role model influence on others in an online survey-based experiment. We randomly expose teachers to profiles of top performing students and inquire whether they consider the profiled top performers to be influential role...

Peer evaluation tournaments are common in academia, the arts, and corporate environments. They make use of the expert knowledge that academics or team members have in assessing their peers’ performance. However, rampant opportunities for cheating may throw a wrench in the process unless,...

This study analyses income dynamics and economic vulnerability in the Republic of Moldova between 2019 and 2023, using data on income and expenditures from the Household Budget Survey conducted by the National Bureau of Statistics. The findings reveal significant socio-demographic disparities,...

This study uses sociometric data to show that social connections in the classroom shape the diffusion of the negative externalities on cognitive achievement generated by abused and neglected peers. We find the strongest negative effects for students who are socially closest to the abused and...

Relying on a reform that increased parental leave generosity, we estimate workplace peer effects in the use of leave, with a focus on fathers. Coworker fathers are more likely to take parental leave when exposed to a higher share of peer fathers, who are exogenously affected by the reform. This...

We investigate how group identity affects belief updating about moral norms. Using a Belief Updating task, we found that individuals follow a cautious version of Bayesian updating. Group identity itself does not directly affect belief updating. However, when given an information signal about the...

Social interactions affect individual behavior in a variety of ways, but their effects on expectation formation are less well understood. We design a large-scale global survey experiment among renowned experts working in 135 countries to study whether peer effects impact expectations about the...

We exploit the 1990-2000 inflow of Yugoslav refugees to Geneva to examine two understudied yet policy-relevant integration mechanisms for refugee pupils: language support classes, provided prior to integration into regular classes, and sorting based on academic ability within regular classes. We...

Situated atop condominium buildings, 'top floor units' (TFU) offer unparalleled views and privacy, courtesy of accessible roofs. This paper empirically examines this status symbol and finds that: (1) TFUs interact with the macroeconomy differently from ordinary units, (2) when considering the...

An enduring question in education is whether team-based peer learning methods help improve learning outcomes among students. We randomly assign around 10,000 middle school students in Karnataka, India, to alternative peer learning treatments in Math and English that vary the intensity of...

Attending kindergarten (KG) has been shown to have persistent benefits, but the peer effects of KG remain largely unexplored. We fill this gap in the literature by using nationally representative panel data on a cohort of middle-school students (grade 7) in China. We demonstrate that when peers...

How do disruptive peers shape academic and career paths? We examine this question by leveraging the random assignment of students to classrooms in Greece and identifying the effects of peer disruptiveness on academic performance and career paths. Using suspension hours as a measure of...

Workers learn on the job from both repetition and peers. Less understood is how specific types of experience and peer characteristics affect on-the-job learning. This likely differs by context (e.g., occupation, tasks, or roles). Absent such knowledge, it is unclear how to optimally assign...

Using a laboratory experiment, we study the evolution of economic networks in the context of fragmented social identity. We create societies in which members can initiate and delete links to others, and then earn payoffs from a public goods game played within their network. We manipulate whether...

We introduce a novel concept, group image concerns, showing that individuals change their behavior and are willing to incur personal costs to cultivate a positive image of their groups. We develop an experimental method to identify and quantify group image concerns, and conduct a series of...
