We conduct a large scale RCT to investigate peer effects in computer assisted learning (CAL). Identification of peer effects relies on three levels of randomization. It is already known that CAL improves math test scores in Chinese rural schools. We find that paired treatment improves the...

We use idiosyncratic variation in gender composition across cohorts within Norwegian lower-secondary schools to analyze the impact of female peers on students' grades and choices of STEM subjects. We find that more female peers in lower secondary increases girls' probability of choosing...

Prior research suggests that class membership is higher in opt-out models than in opt-in models. One of the main concerns with an opt-out model is that it causes a tension with the principle of party autonomy (litigant autonomy). This study explores this tension as well as whether an opt out...

Social interactions with peers during learning have a significant impact on university students' academic achievement. As social ties are voluntary, an empirical estimation of peer effects is exposed to a potential endogeneity problem. To overcome this issue, we propose to define the peer group...

This paper extends the standard work effort model by allowing workers to interact through networks. We investigate experimentally whether peer performances and peer contextual effects influence individual performances. Two types of network are considered. Participants in Recursive networks are...

The influence of peers could play an important role in the take up of social programs. However, estimating peer effects has proven challenging given the problems of reflection, correlated unobservables, and endogenous group membership. We overcome these identification issues in the context of...

Recent evidence has suggested that popularity during high school is linked with wages during mid-life using the Wisconsin Longitudinal Study. The results were shown to be robust to a large set of individual-level heterogeneity included completed schooling, cognitive ability, and personality...

This study investigates whether exposure to peer depression in adolescence affects own depression in adulthood. We find a significant long-term depression peer effect for females but not for males in a sample of U.S. adolescents who are followed into adulthood. An increase of one standard...

Applying a “co-coverage” concept to the Dow Jones Newswire articles, we propose to identify each firm's news-based peers (NBPs) and thereby construct a time-varying firm-centric grouping aimed to augment existing industry classification schemes. The advantage of NBP-augmented schemes over...

In this paper, I study the peer effects in corruption, or more specifically, how sharing hometown or college ties with other officials who have been investigated for corruption affects an official's likelihood of being investigated for corruption himself. In specifications including fixed...
