We built a trajectories-based model of intergenerational mobility using PSID data, analyzing how parental income and family structure across childhood shape adult income. Using an ordered multinomial probability model with functional covariates, we captured the timing of effects while flexibly accounting for high-dimensional factors.

Traditional measures of intergenerational mobility often rely on static or average indicators, obscuring when during childhood parental income and family structure matter most. Our approach allows us to test the timing of these effects and explore whether family resources and stability operate as substitutes or complements in shaping long-term outcomes.

Our findings show that both parental income and two-parent family structure have the strongest influence during middle childhood and adolescence, and that they reinforce each other as complements. These results highlight the need for coordinated policy interventions that address both financial resources and family stability at critical developmental stages, with the goal of maximizing upward mobility.

We developed a nonparametric model to study intergenerational income mobility, allowing for nonlinearities and interactions among factors like race, education, and parental age. Using PSID data, we analyzed how these dynamics affect children’s economic outcomes.

Standard models often overlook complex interactions in mobility. Our approach captures how race and parental education shape opportunities, offering a more nuanced understanding of barriers to economic mobility.

Our findings reveal how interactions between parental income, race, and education create mobility bottlenecks, providing insights for policies aimed at reducing economic inequality and promoting upward mobility.
