This study investigates the impact of a family law reform in Ethiopia that raises the age of marriage entry for females (among other aspects of the law) on the nutritional intake of the children of affected women. Using the difference-in-differences and event-study strategies, the result suggests that exposure to the reform led to a significant increase in dietary diversity (14 percent increase relative to the mean) and a significant increase in the likelihood of consuming fruits and vegetables, fruits and vegetables rich in vitamin A, green leafy vegetables, and animal-source foods. The effect does not appear to be due to changes in women's economic engagement, such as their agency and outside options. Instead, it seems to imply that the implementation of the reform affects women's social status in terms of their decision-making power over sexual and marital relations.
