The Determinants of Inter-Firm trust in Supplier-Automaker Relationships In the U.S., Japan, and Korea

Abstract

In this paper we examine the determinants of supplier trust in the buyer in 453supplier-automaker relationships in the U. S., Japan, and Korea. We define trust and derive a model of its determinants drawing upon (1) an embeddedness (relationship-based) perspective, (2) a processbased perspective, and an (3) economic (hostage-based) perspective. Our findings indicate strong support for the process-based perspective in all countries; embeddedness (e.g., length of relationship) was only important as a determinant of trust in Japan, and the hostage-based variable (stock ownership) was not important in any country. More specifically, we found that high supplier trust emerges when (1) automakers have developed supplier-selection routines that favor incumbents and which maintain a continuing (repeated) exchange relationship with the supplier, and (2) automakers have developed assistance-giving routines to help suppliers solve problems and improve. Although there were some differences across institutional environments, notably higher trust in Japan, the findings are quite robust across the institutional environments. Indeed, in a sample of U.S. suppliers selling to both U.S. and Japanese automakers in the United States, we found that Japanese automakers were more effective than U.S. automakers at building trusting relations with U.S. suppliers. The ability of Japanese automakers to build high levels of trust with suppliers in the United States suggests that the institutional environment may be less important than firm-level practices in the production of inter-organizational trust.
