Separating Gender Composition Effect from Peer Effects in Education

Peer Effects in Sexual Initiation: Separating Demand from Supply∗

Most work on social interactions studies a single, composite effect of interactions within a group. Yet in the case of sexual initiation, there are two distinct social mechanisms— peer-group norms and partner availability—with separate effects and different potential interventions. Here I develop an equilibrium search and matching model for first sexual encounters that specifies distinct roles ...

Separating Disambiguation from Composition in Distributional Semantics

Most compositional-distributional models of meaning are based on ambiguous vector representations, where all the senses of a word are fused into the same vector. This paper provides evidence that the addition of a vector disambiguation step prior to the actual composition would be beneficial to the whole process, producing better composite representations. Furthermore, we relate this issue with...

Peer Effects in Sexual Initiation: Separating Demand and Supply Mechanisms

Most work on social interactions studies a single, composite effect of interactions within a group. Yet in the case of sexual initiation there are two distinct social mechanisms— peer-group norms and partner availability—with separate effects and different potential interventions. Here I develop an equilibrium search and matching model for first sexual partners that specifies distinct roles for...

Peer Effects and Social Networks in Education

Peer Effects and Social Networks in Education This paper studies whether structural properties of friendship networks affect individual outcomes in education. We first develop a model that shows that, at the Nash equilibrium, the outcome of each individual embedded in a network is proportional to her Katz-Bonacich centrality measure. This measure takes into account both direct and indirect frie...
