“…So far, the empirical evidence at the macro-level regarding the emergence of network externalities in telecommunication markets is poor; hence, the research gap--in terms of empirical evidence-is easily traceable. Some past evidence may be found in Chen et al (2019), Tucker (2019, Kumar et al (2021), Ojala and Lyytinen (2022), Prasetio (2022), Weiergraeber (2022), Cosnita-Langlais andRasch (2023) or Xu et al (2023); however, in any of these works, we find evidence associated with network effects as a driver of mobile cellular telephony diffusion on telecommunication markets. The existing empirical evidence strictly related to the process of mobile cellular telephony diffusion in the context of network effects on the macro-level is relatively outdated, since it may be traced in the works of, for example, JOCM 36,5 Arroyo-Barrig€ uete et al (2010), Baraldi (2012), Kiiski and Pohjola (2002), Arroyo-Barrig€ uete et al (2010), Grajek (2010), Grajek and Kretschmer (2012), and Lechman (2017Lechman ( , 2018Lechman ( , 2019.…”
