Effects of disruptive peers in endogenous social networks
Quantitative Economics, Volume 17, Issue 1, Page 92-134, January 2026.This study uses sociometric data to show that social connections in the classroom shape the diffusion of the negative externalities on cognitive achievement generated by abused and neglected peers. We find the strongest negative effects for students who are socially closest to the abused and neglected peer. The fade‐out rate of the negative externality

Skill formation and the trouble with child noncognitive skill measures
Quantitative Economics, Volume 17, Issue 1, Page 135-172, January 2026.This paper develops a framework to address issues of contamination in parent‐reported measures of child noncognitive skills. We estimate a dynamic model in which child and parental skills evolve jointly and leverage information provided by teachers and interviewers to deal with contamination of parent‐reported measures.
