An investigation of the female-male wage gap during the industrial rev
olution in Britain. During the industrial revolution women's wages wer
e substantially lower than men's. This article documents the wage gap
and shows that in most cases it can be explained without reference to
wage discrimination. First, the wage data we have overestimate the wag
e gap; correcting for biases due to measurement error reduces the size
of the wage gap. Second, because differences in productivity were sub
stantial, the corrected wage gap is consistent with these.
