Abstract: Based on longitudinal PSID data, this article examines the trajectory of intergenerational mobility in the United States over the past three decades by employing a time-varying mixed copula model as outlined by Yang et al. (2022). Our findings reveal a gradual decline in intergenerational mobility, particularly in terms of permanent incomes, between parents and children over time. This heightened income inequality persists across various racial and regional demographics, although subgroup analyses unveil some heterogeneous patterns in the paths of intergenerational mobility.
