Mehrotra et al. (2013) observe that family firms listed before 1971 in Japan and run by non-blood heirs outperform those run by blood heirs between 1962 and 2000. They claim that this is due to superior talent, evidenced in succession event studies. Because the authors do not share their data, we attempt replication and find qualitatively similar results. These depend critically on a dummy for predecessor talent, which MMSW base on successful entry into an elite university more than half a century earlier. When excluding this dummy, no significant differential remains. Our results are robust to changes in definition of succession, to adding businesses listed after 1970, and to including more recent data (2001-2015). An alternative explanation is that non-blood heirs are selected into and inherit superiorly performing businesses.
