Production function studies have used the education of the head of the
household or thtr average education of farm workers to assess the con
tribution of schooling to farm efficiency. In this paper I critically
examine the information content of these measures, by developing a tea
m production model which suggests separate education measures to appro
ximate labor quality and managerial skills. Empirical analyses based o
n Chinese farm household data show that thr new measures are statistic
ally superior to the existing alternatives. There is evidence of centr
alized decision malting on the farms where the highest schooling contr
ibutes the most to production efficiency.
