Brand trust is defined in this literature as the willingness of consumers to rely on the power of the brand to realise its stated purpose, and brand affect defined as a brand's ability to draw out a positive emotional arousal in the consumers as a result of its use ([11] Chaudhuri and Holbrook, 2001). Three variants of brand trust are hypothesised by [41] Sheppard and Tuchinsky (1996), on the basis of its content or cognitive antecedents, namely: calculus-based trust, knowledge-based-trust and identification based-trust. Knowledge-based trust is self-explanatory. "Calculus-based" describes a form most commonly encountered in the work environment, which is based on a calculation of the probable effects of perceived rewards and deterrents on the behaviour of the third party. "Identification-based" is most common in personal life, and defines the situation in which the two parties have internalised each other's expectations and intentions to the extent that they do not need to calculate probable outcomes. Regarded as the highest form of trust, it can be developed in the business context, where it may build into the co-creation of joint products or goals, and commitment to company's shared values. [18] Dwyer et al. (1987) have similarly theorised that company's shared values contribute to the development of commitment and trust, while [35] Morgan and Hunt (1994) proposed that they are a direct precursor of trust. [14] Delgado-Ballester and Munuera-Alemán (2001) also found evidence that involvement with the owner-brand influences and moderates brand trust.
