Theorists and empirical researchers in marketing and other fields suggest that fairness is important in developing buyerseller relationships. However, the construct of fairness is still opaque and relatively under-developed. Researchers still do not adequately understand the connection between service fairness and trust. Hence the purpose of this study is to provide a more developed social exchange model which examines the differential effects of different fairness dimensions on trustworthiness, customers’ trust, and other behavioural outcomes i.e. word-of-mouth and loyalty. Data were collected from consumers of financial services and analysed using confirmatory factor analysis and structural equation modelling. Findings of the study will go a long way in helping service providers in building fairness in the business model and nurturing relationship quality amongst consumers and fuelling positive word-of-mouth, and loyalty.
