Network effects

Ever since my first class on social network analysis, I have been both fascinated and intimidated by network effect models. Studying how these models have developed in the last decade, I became interested in writing an accessible review of the key challenges for identifying peer effects as well as conducting a simulation study to compare the different approaches.

Thanks to Weihua An for providing me with the opportunity to contribute to such a review in the Annual Review of Sociology, which can be found here. An extended review that examines some of the peer effect models in greater detail, which I have written as a precursor of the ARS paper, can be found here.

Further, together with Wicia Fang, I am currently examining several peer effect models by means of a statistical simulation to understand their relative performance in the presence of varying degrees of measurement error and confounding (network endogeneity and contextual confounding).

I will use the insights from these two projects to find the optimal research design for the cross-SES friendship project.
