Berry and Parasuraman (1991) suggest that, in the services marketing area, relationships are built on the
basis of mutual commitment. Following the literature, Keh and Xie (2009) define customer commitment as an
exchange partner's willingness to maintain an important enduring relationship.
Previous studies mainly investigate the seller’s commitment with its buyers and conclude that firms
would benefit from strong commitment with their buyers (Dwyer et al., 1987). Commitment has been studied as a predictor of seller’s profit potential with its buyers (Hunt et al., 2006; Barry, 2004). Commitment is used as a
measure for performance (Brown et al., 1995).
