This paper uses the British Household Panel Survey to present the first estimates of the housework-wage relationship in Britain. Controlling for permanent unobserved heterogeneity, we find that housework has a negative impact on the wages of men and women, both married and single, who work full-time. Among women working part-time, only single women suffer a housework penalty. The housework penalty is uniform across occupations within full-time jobs but some part-time jobs appear to be more compatible with housework than others. We find tentative evidence that the housework penalty is larger when there are children present.
