Rapid industrial growth in China coupled with economic reforms in the rural areas has created a growing demand for rural women's labor, though often at substantially lower wages than those earned by men employed in the same sector. An analysis of data collected in rural Guangdong province suggests that households may contribute to the observed male-female market wage differential through their influence in the formation of individuals' reservation wages. Under these circumstances, external employment opportunities, while no doubt serving to increase the household's overall level of income, may, on their own, be a less effective mechanism for raising the economic status of women. On the contrary, market wage signals may serve to reinforce, rather than to ameliorate, sex-based differences that arise within the household. (C) 1999 Elsevier Science Ltd. All rights reserved.
