This paper reviews the theoretical and empirical foundations of peer and network effects, aiming to bridge insights from both literatures. We first analyze the microfoundations of peer effects through linear-quadratic network games, linking equilibrium behavior to network centrality and...

Innovation drives China's high-quality economic development, with corporate R&D investment being key to innovation. Using data from Chinese A-share non-financial listed firms (2010-2022), this study defines peer firms using a four-dimensional dynamic matching method of "year-industry-ownership...

Sick leave in physically demanding warehouse logistics poses persistent challenges for employee well-being, operational performance, and sustainable work participation. This study investigates how warehouse employees and supervisors understand drivers of absence and presence, and which workplace...

AI-driven systems are rapidly moving from decision support to directing human behavior through rules, recommendations, and compliance requests. This shift expands everyday human-AI interaction and raises the possibility that AI may function as an authority figure. However, the behavioral...

This paper studies whether alternative integration-policy framings affect cooperation in ethnically diverse groups. We conduct a lab-in-the-field experiment with 390 adolescents in mixed classrooms in Italy. Within each class, students were randomly assigned to small groups that received either...

This paper measures parents' beliefs about school and peer quality, how information about each affects school choices and student outcomes, and how social interactions mediate these effects. Parents underestimate school quality and overestimate peer quality. Crossrandomized school and peer...

We interpret the increased polarization in Western societies over global economic issues as an interaction of economic forces and shifts in a society's social identity equilibrium. We combine social identity theory with standard small open economy model of international trade to study the effect...

This paper studies trust, reciprocity, and bargaining using a large-scale online experiment conducted in six Latin American countries. Participants played trust and ultimatum games under randomly assigned conditions in which the gender of their counterpart was either disclosed or withheld. On...

This paper examines the impact of neighbourhood social interactions on a household's ability to produce their child's scholastic achievement. A time-varying stochastic frontier model and a spatial Durbin model are used to estimate endogenous and contextual neighbourhood effects on household...

Students' university experience includes both academic and non-academic outcomes, which are shaped by the educational environment in which students interact. We refer to this environment as university climate and measure it along three dimensions: conformity to masculinity-related attitudes and...

Working remotely during the pandemic changed workplace culture for millions of employees and managers, fueling a desire for more flexible work arrangements. About 75 percent of companies now support hybrid work, meaning managers often oversee workers both in and out of the office. Two...

This study evaluates a randomized trial in Côte d’Ivoire, implemented by the Africa Gender Innovation Lab (GIL), which tested whether varying the content and recipient of SMS reminders can increase enrollment among young people who had pre-registered for a skills training program. Messages...

The transition to neighborhood-scale district heating in the Netherlands frequently stalls due to the challenge of achieving a collective agreement among individual homeowners. To explore the micro-dynamics of this collective action problem, this paper introduces an agent-based model that...

Trust in others is essential for the well-functioning of societies. While economists often study its longer-term determinants - such as cultural norms and historical shocks - shortterm fluctuation may be equally critical, particularly during pivotal moments (e.g, elections) or periods requiring...

AI-driven systems are rapidly moving from decision support to directing human behavior through rules, recommendations, and compliance requests. This shift expands everyday human-AI interaction and raises the possibility that AI may function as an authority figure. However, the behavioral...

This paper studies whether alternative integration-policy framings affect cooperation in ethnically diverse groups. We conduct a lab-in-the-field experiment with 390 adolescents in mixed classrooms in Italy. Within each class, students were randomly assigned to small groups that received either...

We establish a new approach to the modeling of cooperation, and we formulate a new solution concept for cooperative games. We do this by constructing a game of cooperation between individuals who exhibit distaste for relative deprivation, RD, in the sense that they experience stress when their...

Do earthquakes strengthen social cohesion or undermine it? While some theories suggest they strengthen social bonds, others suggest they lead to social disintegration. We add to the limited causal evidence on this phenomenon using the 2012 Northern Italy earthquake, and exploit a unique dataset...

This paper examines peer mental health's influence on adolescents' wellbeing, academic performance, and behavior. Using friends-of-friends as an instrument, I find that a one standard deviation increase in friends' mental unwellness is associated with a 0.67 standard deviation increase in one's...

Communication is well known to increase cooperation rates in social dilemma situations, but the exact mechanisms behind this have been questioned and discussed. This study examines the impact of communication on public good provisioning in an artefactual field experiment conducted with 216...

We use the medical specialties of physician-patients with advanced cancer to study the role of knowledge versus networks in treatment choices and patient survival by matching comparable patients with doctors and admission periods to control unobserved doctor quality. Physician-patients are less...

This paper studies the causal impact of social ties and network structure on helping behavior in organizations. We introduce and experimentally study a game called the 'helping game,' where individuals unilaterally decide whether to incur a cost to help other team members when helping is a...

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...

The literature on political socialization highlights the importance of parents and friends, but it is rare to find studies analyzing these socializing agents in the same model. In contrast, friends are often limited to one or a few friends that may not account for the actual effect of friends....
