There was a concern that US buyers might not be highly involved in international sourcing. In fact, 157 surveys were returned stating that the survey subject was not applicable because the respondent’s firm did not purchase from non-US suppliers. Further, in order to elicit valid responses of the perceptions of both members of the dyad, each purchasing manager was asked to forward the survey to a supplier with whom s/he had ‘close and frequent contact.’ The findings from the present study can thus not be generalized to all types of relationships between US purchasing managers and their non-US suppliers. Further, it is possible that US purchasing managers evaluate and select international suppliers, in part, for their adherence to ethical practices. Thus, again, readers should use caution when generalizing the findings beyond the dyad level.
