Recent studies of US elite exam schools have yielded the startling conclusion that such schools improve neither educational achievement nor longer-term educational outcomes. Is the same true for exam schools elsewhere? The system in Turkey is ideal for investigating this question. There,...

Productivity varies greatly among farmers and the source of that variation is not fully understood. Using a unique Indian household survey, we estimate peer effects on agricultural revenue. Results show that 60% of farmers' revenue is explained by peers. Input expenditures and land allocation to...

Peer effects arise in situations where workers observe each others' work activity. In this paper we disentangle the effect of observing a peer from that of being observed by a peer, by setting up a real effort experiment in which we manipulate the observability of performance. In particular, we...

While the current empirical literature on peer group effects in schools highlights that credible causal peer effects cannot be estimated unless parental sorting is taken into account, the present paper highlights that causal peer effects might be conditional on the learning environment in which...

Social preferences and social influence effects ("peer effects") are well documented, but little is known about how peers shape social preferences. Settings where social preferences matter are often situations where peer effects are likely too. In a gift-exchange experiment with independent...

Using an originally constructed dataset that follows 30,000 Italian individuals from high school to the labor market, we analyze whether the gender composition of peers in high school affected their choice of college major, their academic performance and their labor market income. We exploit the...

Do the people around us influence our personality? To answer this question, we conduct an experiment with 543 university students who we randomly assign to study groups. Our results show that students become more similar to their peers along several dimensions. Students with more competitive...

This paper examines how exposure to students identified as gifted (IQ ≥ 130) affects achievement in secondary school, enrollment in post-compulsory education, and occupational choices. By using student-level administrative data on achievement combined with psychological examination records, we...

Charitable fundraisers frequently announce giving by others, and research shows that this can increase donations. However, this mechanism may not put information about peers to the most efficient use if it is costly to inform individuals who are indifferent to peer actions or causes some...

We study whether mothers' labor supply is shaped by the gender role attitudes of their peers. Using detailed information on a sample of UK mothers with dependent children, we find that having peers with gender-egalitarian norms leads mothers to be more likely to have a paid job and to have a...
