“…Signalling theory helps us to associate the underlying difficulties of evaluating products and the relevance of some signals to efficient decision making. Some of these mechanisms that the consumer can use to infer the quality of the product or the performance of the store and that affect their satisfaction and trust are: the warranty (Emons, 1988; Tan, 1999; Biswas and Biswas, 2004), the company's reputation (Anderson and Weitz, 1992; Hawes and Lumpkin, 1986), advertising (Bagwell and Ramey, 1988; Nelson, 1974), the brand (Bart et al , 2005; Rao et al , 1999; Teas and Agarwal, 2000), the value for money relation (Rao et al , 1999), the web site's security and privacy policies (Bart et al , 2005; Belanger et al , 2002), price premium (Dawson et al , 2003), and detailed and objective information about the product (Fiore, 2002).…”
