Are parents' decisions to invest in green equity funds influenced by their daughters? According to the recent literature on female socialization, parenting a daughter is expected to have a positive impact on parents' investment in green equity funds. Based on an original survey among 2,288 French investors, we validate the female socialization in a retail investment context. Raising a daughter increases the likelihood of investing in green equity funds by about 3.87 percent on average. Consistent with the female socialization hypothesis, this effect only stands for male parent investors, when daughters are still in the household and is not significant for separated fathers. Moreover, the amount invested is also significantly influenced by being a parent of a daughter. Our results support the need to better consider the influence of family members in investment in household finance decision-making and the side effects of education on environmental issues.
