In this paper, the authors use the variance across siblings in school characteristics to estimate the effects of school inputs on wages. The analysis uses sibling pairs from the National Longitudinal Surveys of Labor Market Experience of Young Men and Young Women. They find that teachers' salary, expenditures per pupil, and a composite index of school quality indicators have a substantial positive effect on the wages of high school graduates.
