This document examines the relationship between financial development and intergenerational education mobility across countries. It introduces several indices to measure different components of intergenerational mobility, including a structural mobility index (MS) that measures the distance between parental and offspring distributions of education levels, and an exchange mobility index (MEa) that measures positional changes in education levels across generations. Using data on years of education for parents and offspring in 39 countries, the study finds that financial development is positively related to structural mobility as measured by MS, following an inverted U-shape, but is not significantly related to exchange mobility as measured by MEa.
