We examine the pathways by which several dimensions of gender inequality affect fertility and growth in a model with nonunitary households.This approach allows for a corner regime with maximum fertility, the absence of women from the labor market, and gender inequality in education. Policies to ease countries out of the corner regime are promoting mothers' survival and curbing infant mortality, while reducing the social and institutional gender gap (SIGG) is useless. In the interior regime, parents consider the impact of their children's education on their future marital bargaining power, and reducing the SIGG lowers fertility and fosters growth.
