It may be restricted to specific uses or by-pass governments altogether, it may be tied to imports of goods and services from donor countries that limit its effect on the domestic economy, and significant amounts of donor funds could serve as a disincentive for governments to increase the effectiveness of their tax systems for mobilizing domestic resources. Current institutions of global economic governance are characterized by unequal power relationships that determine the space within which national governments can act, and not all players have an equal voice.141 Indeed, most existing institutions of global governance—for instance, the IMF, the World Bank, the G20, the United Nations and the World Trade Organization—exhibit clear power dynamics.142 Women's representation in the top decisionmaking bodies of these governance institutions is at best low and in some cases negligible (see Figure 4.8). Representation of women is, of course, no guarantee that issues of gender equality will be taken up in policy discussions and decision-making processes.
