“…Firstly, past studies on power in supply chains have focused on its 2 influence on resource allocation (Pulles et al, 2014); power asymmetry (Nyaga et al, 2013); 3 commitment (Zhao et al, 2008); relationship strength (Maloni and Benton, 2000); and 4 performance (Crook and Combs, 2007;Molnár et al, 2010). With a few exceptions such as 5 Molnár et al (2010) and Kühne et al (2013), the majority of these studies collect and analyze 6 data from one side of a relationship dyad using a focal firm approach. Analyzing a supply 7 chain at firm or dyadic levels limits understanding the underlying dynamics of the entire 8 supply chain relationships (Molnár et al, 2010;Wu et al, 2010;Kühne et al, 2013;9 Touboulic et al, 2014).…”
