While interest in social determinants of individual behavior has led to a rich theoretical literature and many efforts to measure these influences, a mature “social econometrics ” has yet to emerge. This chapter provides a critical overview of the identification of social interactions. We consider linear and discrete choice models as well as social networks structures. We also consider experimental and quasi-experimental methods. In addition to describing the state of the identification literature, we indicate areas where additional research is especially needed and suggest some directions that appear to be especially promising.
Criminal networks: Who is the key player
- CEPR Discussion Paper
"... We develop a key-player model by allowing for link formation so that when a person is removed from a network the other individuals can form new links while still optimally providing crime effort. We then put our model to the test, using data on adolescent delinquents in the United States, and provid ..."

We develop a key-player model by allowing for link formation so that when a person is removed from a network the other individuals can form new links while still optimally providing crime effort. We then put our model to the test, using data on adolescent delinquents in the United States, and provide new results regarding the identification of peer effects. This is done by a structural estimation and simulation of our model. Compared to a policy that removes randomly delinquents from the network, a key player policy engenders a crime reduction that can be as large as 35 percent. We discuss how to implement the key-player policy in the real world, primarily within criminal networks, but also within financial, R&D, development, political and tax-evasion networks.
Peer Effects on Undergraduate Business Student Performance

We evaluate the endogenous peer influence of students in one U.S. public University College of Business. In particular, we measure the peer effect on student grades. This study utilises an exclusion restriction approach similar to De Giorgi et al. (2010) to estimate the endogenous peer effect. Our results support the finding that a student’s classroom performance has a significant effect on their peers. Overall, our results suggest a negative peer effect. However, we find that the direction and magnitude of the peer effect is sensitive to the student’s own average ability and that of their peers.

In this paper, we exploit a rich longitudinal data set to explore the forces that, during high school, shape the development of aspirations to attend univer-sity and achieve academic success. We then investigate how these aspirations, along with grades and other variables, impact educational outcomes such as going to university and graduating. It turns out that parental expectations and peer factors have direct and indirect effects on educational outcomes through their impact on both grades and aspirations. Policy measures that enlighten parents about the value of education may positively modify educa-tional outcomes. Résumé Cet article profite d’une riche base de données longitudinales qui permet d’explorer les influences qui, au cours des études secondaires, poussent les étudiants à aspirer à une formation universitaire et à atteindre ainsi une forme de réussite académique. Nous étudions ensuite comment ces aspirations, les notes obtenues, ainsi que d’autres variables, exercent une influence sur l’éducation, comme les études universitaires et l’obtention d’un diplôme.

Using the exact home addresses and the complete high school application records, I esti-mate neighborhood impact on high school choices in the New York city. The identification of neighborhood interaction effects rely on variation across census blocks within block groups. With the assumption that blocks within a block group are formed roughly randomly with respect to household attributes, I find that students residing in the same census block are more likely to to rank same schools. The estimated effects are stronger among students with homogenous ethic and academic backgrounds. For a robustness check, I take advantage of the location coordinates at individual level to rank students ’ neighbors by distance and com-pare the choice similarity between closest versus next closest neighbors. This distance rank approach further confirms the existence of social interactions. It finds that social interaction effects decay quickly over distance and immediate neighbors have greatest impact on school choice. Further, I study the nonlinear social effects across students of different achievement levels and find that low achiever are more likely to rely on the neighborhood interactions when making choices.
