The trickle-down effect of trust in business-to-business relationships: How can a supplier ensure cooperation from multiple customers?

Although several interfirm cooperation studies have expanded the unit of analysis from dyads to triads (networks), there is scant literature focusing on whether and how a supplier’s relationship with a customer influences its relationships with other customers. Individual relationship dyads are not isolated but interact with one another. Particularly, mutual trust in a supplier–customer relationship dyad may influence other customers’ cooperative behavior. This cross-dyadic influence is called the “trickle-down effect of trust.” A hypothesis for the mechanism by which this effect occurs was generated, focusing on the customers’ demand information offerings as a cooperative behavior. The results of an empirical analysis indicate that (1) a supplier’s mutual trust with its primary customer encourages nonprimary customers to offer their demand information to the supplier and (2) the quality of information from customers helps the supplier to make their new product more meaningful.
