In these two contexts, relationship marketing is interested not only in classic underlying parameters of economic exchanges, but also takes into account non-economic characteristics, especially trust and commitment, seen as important characteristics in social exchange-based relationships (Grönroos, 1997, p. 407). Because of this, the commitment-trust theory (Morgan & Hunt, 1994) has become one of the fundamental theories within the relationship marketing paradigm, where trust and commitment are seen as mediators to the antecedents and determinants of buyer-supplier relationship performance (Morgan & Hunt, 1994). This has been empirically cross-validated particularly in B2B marketing settings (e.g. Friman et al., 2002) and buyer-supplier alliances (Yang et al., 2008).
