Recently, increasing researchers from a variety of business disciplines are finding that trust can lower transaction costs, facilitate inter-organizational relationships, and enhance manager-subordinate relationships. At the same time, we see a growing trend toward globalization in establishing alliances, managing and hiring employees, and entering new markets. These trends suggest a need to view the influence of between buyer-supplier relationship on concept of trust from the perspective of national culture. Drawing on theories from several disciplines, we developed a framework that identifies and describes five cognitive trust-building processes that help explain how trust develops in business contexts. We include a series of research propositions demonstrating how national culture influence buyer-supplier relationship on the trust-building processes, and we discuss implications for theory and practice.
