Educating girls quite possibly produces a higher rate of return than any other investment(投
资)available in the developing world．Women’s education may be an unusual field for experts On economy(经济)，but improving women’s contribution to development is actually as much all economic as a social business．And economics provides an explanation for why so many girls are
deprived of an education．
Parents in low-income countries fail to invest in their daughters because they do not expect them to make all economic contribution to the family：girls grow up only to marry into somebody
else’s family and bear children．Girls are thus seen as less valuable than boys and are kept at home to do housework while their brothers are sent to school．Ignoring women’s education is therefore in a bad circle．
An educated mother, on the other hand, has greater earning abilities outside the home and faces an entirely different set of choices．She is likely to have fewer but healthier children and can insist on the development of all her children, making sure that her daughters are given a fair chance．The education of her daughters then makes it much more likely that the next generation of girls，as well as of boys，will be educated and healthy．The bad circle is thus changed into a good
circle．
Educating women has great social benefits and great economic advantages as well．Most obviously, there is the direct effect of education on the wages of female workers．Wages rise by 10 to 20 per cent for each additional year of schooling．Such big returns are impressive by the standard of other available investments，but they are just the beginning．Educating women also has a significant effect on health practices, including family planning．
