“…By 2010, more than 50 industries displayed high levels of global concentration, where high concentration is defined as more than 50 per cent of the market being controlled by the top four players (Carr and Collis, 2011). Global concentration is evident in a variety of industries, including airlines (Ramón-Rodríguez et al , 2011), wind turbines (Lema et al , 2011), automobiles (Van Biesebroeck and Hashmi, 2007), steel (Giarratani et al , 2013), electronics (Sturgeon and Kawakami, 2010), beer (Hoenen and Hansen, 2013), telecommunications (Nolan et al , 2008) and agricultural seeds (Howard, 2009). In the emerging internet-based industries, global concentrations appear to be extraordinarily high, as evidenced by the market positions held by companies such as Google, Facebook, Amazon, Apple and LinkedIn.…”
