Preliminary–please do not cite without permission In the US, women tend to have lower levels of financial literacy than men. This is consistent with a household division of labor in which men manage finances. However, women also tend to outlive their husbands, so they will eventually need to take over this task. Using a new survey of older couples, I find that women acquire additional financial literacy as they approach widowhood. At an estimated increase of 0.04 standard deviations per year approaching widowhood, 80 % of women in my sample would catch up with their husbands prior to the expected onset of widowhood. I also demonstrate that these findings are due to actual increases by women and are not merely an artifact of cognitive decline among older men. These results are consistent with a model in which the household division of labor breaks down when a spouse dies. The model shows that women have an incentive both to delay acquiring financial knowledge and also to begin learning before widowhood.
