“…Extensions to this framework, which were specifically applied to tourism gravity models, evolved into more complex formulations (Morley et al, 2014) where flows between two countries are treated as "a function of a matrix of interrelated factors that includes the public and private sector structures supporting flows, diplomatic relations, and economic and noneconomic factors" (Prideaux, 2005: 781). Therefore, the latest empirical studies have adopted the augmented version of the gravity model combining a variety of factors such as real exchange rates (Khan et al, 2021), consumer price index (Altaf, 2021), temperature difference (Cró et al, 2021), colonial links (Cevik, 2020), political instability (Ibragimov et al, 2021), infectious diseases (Cevik, 2020), common border (Ibragimov et al, 2021;Groizard et al, 2021), and common language (Dropsy et al, 2020;Okafor et al, 2021). One of the most likely contemporary forces to influence international tourism flows is related to the source market´s level of digitalization development and access to digital platforms, as a factor that eases information asymmetry issues (Baggio and Baggio, 2013).…”
