 Moreover, the positive returns to capital are found to be completely concentrated among enterprises owned by men, a fact that cannot be explained by differences in the entrepreneurs' characteristics, but rather suggests that capital given to female entrepreneurs is more likely to be consumed or misinvested by other household members.In further work on this issue, they randomly offer both existing and potential female microentrepreneurs either the ILO's Start-and-Improve Your Business (SIYB) programme or a combination of SIYB training and a cash grant, then finding that the training only has an impact on business profitability for new entrepreneurs and that the impact of the combined support dissipates in the second year.In a comprehensive review of research on business trainings in developing countries, McKenzie and Woodruff conclude that business trainings generally have only modest impacts on existing firms, partly because firm owners' application of the taught practices is often limited, though trainings seem to help prospective entrepreneurs launch start-ups faster and better.
