“…If endogenous, this free-float adjustment will invalidate random index assignment (see Appendix A of Schmidt and Fahlenbrach, 2017). Indeed, Wei and Young (2017) show that there exist important ex-ante differences prior to index reconstitution between the ownership structure of firms with low index weights in the Russell 1000 and firms with high index weights in the Russell 2000. 20 do not use sharp RDD.…”

“…There is currently a debate about how to use an RDD for causal inference with Russell index reconstitutions (e.g., Appel et al, 2016a,b;Schmidt and Fahlenbrach, 2017;Crane et al, 2016;Young, 2018;Wei and Young, 2017). Issues include: (a) the bandwidth choice, (b) which investors are assumed to be affected (e.g., mutual funds that specifically index Russell vs. quasiindexers), and (c) the fact that the proprietary May end market cap that Russell uses to assign index membership (the forcing variable) is not observable to researchers.…”

“…To resolve the endogeneity concern, we employ a regression discontinuity (RD) design with Russell indexes. Recent papers, however, point out some endogeneity concerns and challenges for the identification strategy due to Russell's policy that determines index memberships and weights (Crane et al, 2016;Appel et al, 2018;GloBner, 2018;Wei and Young, 2018). After membership is determined by the end-of-May market capitalization, stocks within indexes are adjusted to include only those shares available to the public, referred to as "free float."…”

“…This creates some endogeneity issues for the identification strategy. See, for example, Appel et al (2016Appel et al ( , 2018, Crane et al (2016), GloBner (2018), and Wei and Young (2018).…”
