“…Only three works offer explanatory or predictive theoretical contributions at this level of analysis (Hackett & Dilts, 2004a;Kim & Wagman, 2014;Theodorakopoulos et al, 2014) Nearly half of the studies at this level of analysis fall into the first category, "Describe, Classify, Compare," which consists of those that provide high-level or rich descriptions of ESOs, classify them into typologies, and/or compare forms. Examples of studies that primarily "describe" include: incubators (e.g., Carayannis & Von Zedtwitz, 2005;Hansen et al, 2000); accelerators (e.g., Adomdza, 2016); maker spaces (e.g., Browder et al, 2019); hubs (e.g., Bachmann, 2014;Littlewood & Kiyumbu, 2018); other related forms (e.g., Pollio (2019) study of a Startup Weekend or Nowak and Grantham (2000) discussion of virtual incubators). Generally, these works list the resources and services the ESO provides (office space, networking, legal or financial advice, direct or indirect funding, etc.…”
