“…cohorts born 1952-75 (e.g., Hertz, 2007Lee and Solon, 2009) or later (Chetty et al, 2014), a finding that is surprising given the concurrent increase in income inequality, the theoretical link between inequality and mobility, and the observation that gaps in parental inputs have increased (Blanden, Doepke and Stuhler, 2022). However, Davis and Mazumder (2022) find that mobility declined sharply for cohorts born 1957-64, in comparison with those born 1942-53, and Justman and Stiassnie (2021 find declining mobility when extending the time frame considered by Hertz (2007) and Lee and Solon (2009) to more recent years.…”
