In recent years there has been a plethora of empirical papers by economists concerning the effects of academic rank in school or college on subsequent outcomes of students. We review this recent literature, describing the difficult identification and measurement issues, the assumptions and...

We study both endogenous and exogenous peer effects in worker productivity using an explicit network approach. We apply this method to data from an in-house call center of a multinational mobile network operator that include detailed information on individual performance. We find that a 10%...

We investigate whether restatements announced by economically related firms influence the contract terms a borrower receives from lenders. A restatement by a major customer firm increases the loan spread of a borrower by 11 basis points, on average. The contagion effects of customer restatements...

We introduce a novel use of genetic data for studying social influences on behavior: Using data from the National Longitudinal Study of Adolescent to Adult Health (Add Health), we deploy the distribution of genotypes in a given grade within a school to instrument the influence of peer smoking on...

We use unique data on employee decisions in the employee stock purchase plans (ESPPs) of U.S. public firms to measure the influence of networks on investment decisions. Comparing only employees within a firm during the same election window and controlling for a metro area fixed effect, we find...

This paper provides evidence of a novel facet of peer effects by showing how peer personality affects educational achievement. We exploit random assignment of students to university sections and find that students perform better in the presence of more persistent peers and more risk-averse...

In order to develop the skills and competences required in a professional environment, university students have to reflect on their own role in the learning process. The traditional methods of assessment do not assess reflective thinking, critical thinking, self-evaluation and peer evaluation....

Women have historically been underrepresented in science, technology, engineering and math (STEM) jobs. There are concerns that the persistence of this gap over time is in part due to path dependence and the historical lack of high-performing women in these fields. This paper uses administrative...

Obesity among children is an important public health concern, and social networks may play a role in students' habits that increase the likelihood of being overweight. We examine data from South Korean middle schools, where students are randomly assigned to classrooms, and exploit the variation...
