“…Where overlap was reviewed positively, papers most often recognized more than one benefit. Of the 34 papers that identified benefits of regulatory overlap, 21 listed two or more of the different Tier 3 codes (see, e.g., Gersen, 2013; Naso et al, 2020; Weaver, 2014) with 10 papers including over three or more codes (see, e.g., Aagaard, 2011; Buzbee, 2017; Duranske, 2017) and one paper was coded with seven different identified benefits (Babcock, 2012). Interestingly, many of these papers also argued that regulatory overlap could be a problem.…”
