The World Bank claims to have become the defender of women's rights, urging national governments to 'invest more in women in order to reduce gender inequality and boost economic development'. Through its Women in Development Programme (WID), adopted throughout the developing world, the Bank defines the ground rules on gender policy. A market oriented approach is prescribed, with a monetary value attached to gender equality: women's programmes are to be framed in relation to the opportunity cost and efficiency of women's rights.
