“…Another strand of research has focused on extrinsic quality cues, where price, geographical origin and brand name predominate (Barrena & Sánchez, 2009;Bower, Saadat, & Whitten, 2003;McEachern & Schröeder, 2004). The set of factors used for food quality evaluation has recently grown to include food safety, traceability, the type of livestock production system, animal welfare and organic production methods (Bardaji, Iráizoz, & Rapún, 2009;Bernués, Olaizola, & Corcoran, 2003;Caswell, 2001;Henson & Northen, 2000;Loureiro & Umberger, 2007;McEachern & Schröeder, 2004;Verbeke, 2001). These intrinsic and extrinsic product attributes have also been shown to play an important role in determining consumers' preference structures, intent to purchase and, more specifically, willingness to pay (WTP) a premium for various product characteristics (Killinger, Calkins, Umberger, Feuz, & Eskridge, 2004a;Killinger, Calkins, Umberger, Feuz, & Eskridge, 2004b;Tonsor, Schroeder, Fox, & Biere, 2005).…”
