This paper develops a learning model of cultural change to investigate why women's labor force participation (LFP) and attitudes toward women's work both changed dramatically. In the model, women's beliefs about the long-run payoff from working evolve endogenously via an intergenerational learning process. This process generically generates the data's S-shaped LFP curve and introduces a novel role for wage changes via their effect on the speed of intergenerational learning. The calibrated model does a good job of replicating the evolution of female LFP in the United States over the last 120 years and finds that the new role for wages was quantitatively significant.
