This article estimates a partially linear model that permits non-linearities of unspecified form in the school quality-earnings relationship. It examines the joint effect of teacher education and pupil-teacher ratios on 1990 earnings using NLSY data. It finds some evidence of non-linearities in this relationship, and that teacher education has a positive effect on log wages at some points in the pupil-teacher ratio support.
