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....

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,...

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...

Very little has been observed regarding household decisions around margin use. Using the 2021 wave of the National Financial Capability Study (NFCS), this study investigates margin use as both a debt and an investment decision. Using probit analysis and observing correlations, relationships...

The Chinese government promises to reach the carbon emission peak by 2030 and achieve the carbon neutrality by 2060. Renewable energy development is important for achieving this target. Local governments' behaviors and attitudes might be influenced by neighbors. Therefore, this study uses...

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 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...

Using millions of siblings in the U.S., we detail three findings that quantify whether siblings influence one another to vote in national elections. First, and descriptively, younger siblings are 10 percentage points (50 percent) more likely to vote in their first eligible election when their...

This paper investigates the existence and moderating mechanisms of the peer effect in mergers and acquisitions for green innovation (GIM&As). Using Chinese GIM&A data from 2010 to 2023, we find that there is peer effect in GIM&As. In other words, a firm's GIM&A decisions will be affected by its...

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...

Using the universe of high school and college admissions data in Croatia, we geocoded nearly half a million students' residential addresses to investigate how their college and major choices are influenced by older neighbors and peers. Using an RDD to exploit time and program variation in...

The first edition of this guidance was published in 2020. It was created by experts from across the EU, with valuable input from the European Commission, the United Nations High Commissioner for Refugees and the European Council on Refugees and Exiles. The development was facilitated and...

How does polarization - as measured by mistreatment of political rivals - spread? In an online experiment, participants choose between splitting financial resources equally or discriminating against a member of the opposing political party. We vary the information subjects receive about others'...

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...

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...

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...

Adolescents' educational choices are shaped by their peers. Using administrative data covering the entire population of Italian middle school students, we show that exposure to high-achieving male peers in math reduces the likelihood that girls choose a scientific high school track. To...

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 study the impact of classroom rank on children's learning using a unique experiment from Ecuador. Within each school, students were randomly assigned to classrooms in every grade between kindergarten and 6th grade. Students with the same ability can have different classroom ranks because of...
