“…Another potential mechanism for ECE programs' persistent effects revolves around the notion of institutional-gateway processes defined as "certain kinds of interactions with institutions at critical moments in the life course [that] put constraints on individuals' outcomes far into the future" (Bailey et al, 2020, p.72). Institutional gateway processes like financial aid application tutorials, SAT test preparation, or grade retention, while not necessarily coupled with skill formation, can nonetheless play a role in the mechanisms supporting long-run impacts, by inducing favorable changes in subsequent developmental environments (e.g., Bettinger et al, 2012;Buchmann et al, 2010;Eren et al, 2022;Hurwitz et al, 2017;Manacorda, 2012).…”
