“…This is since interdependence between countries can be a result of sociopolitical phenomena such as historically shared ties or levels of interactions, or other network structure (Beck et al 2006;Ertur & Koch, 2011). Spatial econometrics studies using non-geographical spatial matrix are gaining attention recently, such as Qu et al (2021), Amidi & Majidi (2020), and Ho et al (2018Ho et al ( , 2013)using trade-related matrices; Baysoy & Altug (2021), Ahmad, (2019), Ganau (2017), Ahmad & Hall, (2017), Arbia et al (2010) institutional proximity matrices; Zhang et al (2020), Caragliu & Nijkamp (2016) On the back of this development, this paper formally employs spatial econometrics analysis to investigate the effects of FD and institutions on the growth process of the countries under study, and this constitute the paper's first contribution to the existing FD-growth literature. Secondly, apart from using the conventional geographical-based spatial dependence, this paper extends the measure to institutional proximity concept, apparently rarely explored in the FD-growth analysis.…”
