The experiment found evidence in the fact that the direct manipulation of the policy maker's identity has an effect in the policy outcome. More specifically, they found significant results in policy decisions when there is reservation for women in local government. 
Under reservation policy there is more investment in public goods that are linked to women's preferences and less in those linked to men's preferences. The authors also make sure that this differences in the policy outcome are due to the gender of the policy maker and not because another reasons, such as a greater concern of women about general interests, as the literature suggests. 
This paper is important, according to the authors, because reservations for women are increasingly being implemented at various levels of government also in other countries, such as Morocco, and, even at the lowest level of a decentralized government, all mechanisms that affect politician's identities may affect policy decisions.
